Asus P8P67

The P8P67 motherboard is a motherboard that fits people who are willing to make small sacrifices, but are not willing to sacrifice overall performance of that component. In a lot of ways, the P8P67 motherboard is nearly identical to its bigger brother the P8P67 EVO motherboard (Review HERE), with only having a few minor differences separating these two motherboards apart. The P8P67 motherboards still retains Asus’ core features, DIGI+VRM (You can read more about it HERE), Asus very own TPU/EPU microprocessors (Please visit this link HERE), also Asus’ very own AI Suite II, not to forget that the P8P67 motherboard still can be overclocked just as high as its bigger brother the P8P67 EVO motherboard. So what are the differences between these two motherboards, well to start off with the visual differences, the P8P67 motherboard only uses 1 Ethernet port vs 2 on the EVO motherboard, the P8P67 motherboard does not have onboard on/off buttons. The P8P67 motherboard does not use the Warning LED system like that on the EVO motherboard, and for the final major difference between the two motherboards, (P8P67, P8P67 EVO) is that the EVO motherboard has 3 full PCI-E VGA ports, while the P8P67 motherboard only has 2 full sized PCI-E ports. So in the reality of things, there is not much of a difference between these two motherboards, visually speaking of coarse.

Which leaves the DGC to figure out what exactly is the true difference between the P8P67 and the P8P67 EVO motherboards. And, if there are any major differences between these two motherboards, will it be a major difference? The only way we can find out is for us to dive in, and start cranking.

Packaging

Starting off on the packaging of the Asus P8P67 motherboard, similar to the Asus P8P67 EVO motherboard, Asus does give us plenty of information about this motherboard and what its key features are, as well as informs the user that this is indeed a B3 chipset revision.

Once again Asus does do a pretty good job on ensuring that their motherboards are well protected from the rigors of shipping.

Lets take a quick look at what comes bundled with the P8P67 motherboard. Not much in the way of a lot of added extras, but enough to get us moving in the right direction for our computers. Asus includes 2 users manuals, driver disk (which is inside one of the manuals), a rear IO port cover (For the paste few years Asus been using this type of shielding on the Rear IO cover, Asus calls this their Q Shield, this shield helps reduce the amount of EMI (Electro Magnetic Interference) from reaching the motherboard. Asus also pads this rear IO shield to add a nice touch to help minimize cuts and bruises when we install our motherboards into the chassis) , 4 SATA cables (2 are SATA 3 Gb/S, 2 are SATA 6Gb/s), a rear USB 2 expansion port with an eSATA port, and finally we get a USB standoff header, and a front IO stand off header.

Time for me to do the overview of this motherboard.

This time I decided to start off on the EPU switch and the Mem Ok button area. Just like the EVO motherboard, this motherboard  fully supports Asus’ very own TPU/EPU capabilities; as well as, Mem Ok. The Mem Ok button is for if and when we might have a memory incompatibility with this motherboard, we press this button while our computer is turned off, and the motherboard will cycle through various timings, frequencies, and voltages in hopes to get you up and running quickly.

This is what Asus has to say about the EPU switch and the Mem Ok button located here:

EPU:

This switch initializes a quick OC. This is focused at first time builders or builders with no OC knowledge. All the user needs to do is flip the switch and it will overclock the CPU. A 2500K will approx reach 4.3GHz and a 2600K will approx reach 4.4GHz. This OC is designed to be used with the stock cooler or aftermarket heastinks. In addition it maintains using offset voltage option for voltage delivery ensuring an efficient way of supplying voltage under an overclock configuration.

Mem Ok:

This is a special hardware IC that interfaces with the Turbo V Controller IC on the board. Through this controller and button users can help to eliminate issues with memory.

In either a situation of memory causing a post issue, boot issue, degraded dimm performance or mis match dim configuration mem ok can attempt resolve the issue via adjustments to the DRAM frequency, timings and voltage. Through these adjustments the memory parameters are adjusted to allow for a potentially successful boot. In addition some users use it as a semi clear cmos. This is due to the fact it will reset frequency parameters but not clear the entire bios and other non frequency related adjustments ( SATA operation, disabled devices, fan settings etc ).

Zooming out from the EPU switch and the Mem Ok button, we get to see the memory DIMMs. Due to the nature of the 2600K 1155 socket CPUs, we can only use a Dual channel memory, so there are only four memory DIMMs available. Right below the memory DIMMs, is the main 24 pin power plug, then just off to the left of the main 24 power plug, we get to see the included USB 3.0 front IO header. Jumping to the far right hand side of the motherboard (edge of it) we can see fan header #1 which is located by the corner, and fan header #2 is located about a third way up the motherboard.

I just found this out about the Asus P8P67 motherboard, is about the memory DIMMs themselves. Normally if and when I do need to run just one stick of memory, I just got into the habit of placing it in the first and third memory DIMM, Asus has giving us the flexibility of being able to use any of the four memory DIMMs with either 1 stick of memory, or two sticks of memory. We are no longer confined to having to place the memory in a specific ports like we had to do previously. this is called Memory Auto Banking Booting.

Making our way over to the PCH area. This motherboard also support 4 SATA 3Gb/s HDDs, as well as 4 SATA 6Gb/s HDDs. The Lt Blue SATA ports are the SATA 3 Gb/s HDD hook ups (Native), the Grey SATA ports are the SATA 6 Gb/s HDD hook ups (Native), and the darker blue SATA ports are the Marvel controlled SATA 6 Gb/s HDD hook ups. Moving to our left, we can make out the front IO on/off header on the corner of the motherboard, followed by a COM header (Did I just say a COM port? scratches head and looks at picture again, this time more closely, Yep that is a COM header, interesting……) Right above the COM header, are the three included front USB 2.0 headers. If we look just to the right of the COM header is where fan header # 3 is located. The TPU microprocessor is located in the same exact spot as it did on the P8P67 EVO motherboard, nestled right in between the PCH heatsink and the fan header.

Lets see how the PCi/PCI-E expansion ports are laid out shall we. We are going to start from the right and work our way left. The first expansion port we see is a PCI-E x1 port, followed by a full PCI-E VGA x16 port, we get another PCI-E x1 port, this port will be rendered useless after you put in a video card into the full PCI-E x16 VGA port. Similar to the P8P67 EVO motherboard Asus placed a PCI port right behind the second full PCI-E x16 VGA port, (this is not your average everyday VGA expansion port, read below for more information), after the secondary PCI-E VGA port we get two more PCI expansion ports. Looking at the far left edge of the motherboard, starting from the included TPU switch, we get a 1394 Firewire Front IO header, then right above this header is the front IO audio header.

The Black Secondary PCI-E VGA port, will not split the PCI-E lanes that come from the primary PCI-E VGA port. Due to the nature of the 2600K, and the P67 chipset, there are only 16 PCI-E lanes available for the VGA cards, if you use one video card, that video card would get the full x16 PCI-E lanes. If we decided to use a second video card, then the x16 PCI-E lanes would be split (or shared) between the two video cards. The P8P67 motherboard does not split or share the same PCI-E lanes from the primary PCI-E VGA port, this PCI-E VGA port (again the black one) only has a x4 PCI-E lanes available to it, but there is a catch to this. I found this out the hard way, the black PCI-E VGA port defaults at running with an x1 PCI-E port. To enable the x4 PCI-E lane capability, we have to enable that in the EFI BIOS, but if you enable the x4 PCI-E capability on the black PCI-E port, you will borrow the PCI-E lanes from the first, and second PCI-E x1 ports; as well as, the USB 3.0 front IO header. I use a Creative X-FI PCI-E x1 sound card, at first I thought that the black PCI-E port was a x8 VGA port, but when I was installing drivers for my fresh Windows 7 install, I went to go check and see if my two 6970 video cards were running in Crossfire; they were not. I looked in the manual, and it stated that this secondary VGA PCI-E port only uses an x1 or a x4. So I rebooted the computer, entered the EFI BIOS, set the secondary VGA PCI-E port from an x1 to a x4 (keep in mind that the Creative sound card is in the first PCI-E x1 port). After doing this I rebooted the computer, and now I lost all sound from my Creative X-FI sound card. Well at least I got my crossfire to enable on the 6970 video cards. After fumbling through the manual once again, I found out that the black PCI-E (secondary VGA PCI-E port) shares/borrows the same PCI-E lanes from the listed above components.

This is what Asus has to say about the TPU switch

This switch initializes a quick OC. This is focused at first time builders or builders with no OC knowledge. All the user needs to do is flip the switch and it will overclock the CPU. A 2500K will approx reach 4.3GHz and a 2600K will approx reach 4.4GHz. This OC is designed to be used with the stock cooler or aftermarket heastinks. In addition it maintains using offset voltage option for voltage delivery ensuring an efficient way of supplying voltage under an overclock configuration.

An up-close shot of the TPU switch that Asus uses on this motherboard.

Looking at the area around the CPU socket. The CPU socket area is fairly clear of any large obstacles, so we should not have any major issues on being able to use large CPU coolers. Similar to the P8P67 EVO motherboard, the upper right CPU mounting bolt hole, that is right next to the 2 VRM heatsinks (in picture upper right) sits a bit close. This is not enough of a major problem, just needs to be mentioned.

Now time for me to wrap things up with the overview of this motherboard. Taking a look at the rear IO ports of the P8P67 motherboard. Starting from our left, then working our way to the right, up first are the everyday standard 2 PS2 port headers, since most keyboards and mice are USB nowadays, I would have preferred to have seen a single PS2 port with 2 USB headers here (personal preference). Moving to the right, this time Asus did not include two audio optical outputs, they opted out only for one audio optical port. Up next is the BT GO (allows us to connect to this computer remotely with our phones, or BT devices, this is a rather cool feature) with 2 USB 2.0 ports. Up next is just a 2 USB 2.0 USB header, then we get a 1394 Firewire with 2 more USB 2.0 ports on the same header. Moving on further to our right, we get a single Ethernet port with 2 USB 3.0 ports header, then finally we get to the 8 channel onboard analog audio ports. The one thing I would like to have seen included, is a rear Clear CMOS button.

Extra Pictures

EFI BIOS

This is what the EFI BIOS looks like under the AI Tweaker tab in the EFI BIOS. Looking at these SS (screen shots), we can see that the 2600K CPU uses a 100 BCLK, we do not have a QPI voltage adjustment for the new 2600K CPU. So consequently we are somewhat limited on our BCLK adjustments. The BCLK does not adjust by whole numbers, 1,2,3, instead the BCLK adjustment uses a more fine tuned adjustments of 0.1, 0.2, 0.3. Both the Advanced and the EZ EFI BIOS portions, have an “auto overclocking”, capability, in the advanced EFI BIOS, this is named the OC Tuner, by pressing the OK option, the EFI BIOS will reboot the computer, and cycle the computer for the best possible overclock. In this case the OC Tuner gave me a roughly a 4.5 GHz overclock on the 2600K CPU. The Asus P8P67 motherboards, do not overclock the CPU by the base CPU multiplier (been there, tried that), we can only use the turbo multiplier of the 2600K CPU.

Asus always gives us two different ways we can adjust the CPU voltage, we can either use a standard voltage setting (where we set the actual voltage the CPU) will use, or we can use the over voltage setting (Offset). I highly recommend using the over voltage setting (or offset voltage control).

I will be comparing the Asus P8P67 EVO motherboard up against a Core i5 750 1156 socket CPU with a Gigabyte P55A-UD4P motherboard, and a Core i7 970 CPU on an Asus Rampage II Extreme X58 based motherboard. All motherboards will be using their default CPU clock speeds with turbo enabled for the comparisons only. I will be including an overclocked Asus P8P67 paired up with an Intel Core i7 2600K 1155 CPU (Sandy Bridge) motherboard, this will only be used as a reference only, so you can get an idea of the level of performance you could possibly get if you choose to overclock this motherboard/CPU combination. A fresh Windows 7 64 bit install was performed prior to any official testing, the results will be based off of an average of 3 runs per benchmark to ensure that I did not get any erroneous readings, and to make sure my results are accurate as possible. For the memory frequencies, I allowed each of the tested motherboards to determine the actual speed of the memory after I loaded up the BIOS defaults, in this case the Core i5 750 CPU used the memory frequency of 1333 MHz with a 7-7-7-20 timings, the Core i7 970 used a 1600MHz with 8-8-8-24, and the Core i7 2600K used 1600 8-8-8-24 timings on both tested motherboards, the P8P67 EVO, and the P8P67 motherboard. Your results may and will vary greatly from my own.

For the Graphics testing, I will be doing something a bit different. I will not be including the Core i7 970, or the Core i5 750 CPUs in on the fun. I will be comparing the P8P67 motherboard with only the P8P67 EVO motherboard in both a Crossfire configuration, and in a single video card configuration. I want to see if having a x4 limitation on the secondary video card will hurt performance when being compared to a motherboard that uses a x8 x8 multi GPU configuration. Considering that both of these motherboards are fairly equal to one another, this would make an opportune moment to conduct this “Highly Scientific Experiment”, OK well not exactly “Highly Scientific”, but close enough for the government. If you want a comparison on what the difference between the Core i5 750 CPU, Core i7 970 and a Core i7 2600K please feel free to look at this review HERE, also you can look at this article where I compared a Core i7 970, Core i5 750, and a Core i7 930 both stock clock speeds and overclocked speeds HERE.

Overclocking

Overclocking the P8P67 motherboard went a whole lot more smoother then what it did on the P8P67 EVO motherboard. Of course I had some practice with the EVO motherboard prior to moving to the P8P67 motherboard, so naturally overclocking will go a lot smoother. This time I did not try and see if I could do a 200 BCLK/FSB overclock, because I already knew that was going to be a fight I was not going to win, but I still wanted to use the highest possible BCLK/FSB I could get away with. The way I approached this new way of overclocking, I turned off Turbo, and then set the CPU base multiplier to a mere 20 (this will eliminate any CPU related overclocking), I manually adjusted all of the voltages to their stock setting, and added a notch or two for good measures. Now I started upping the BCLK by 1 (the new EFI BIOS does the BCLK in increments of 0.1) and rebooted the computer and entered Windows to do some stability testing. I kept going till I started having instability issues and then backed the BCLK by 1. So this new BCLK I was at stable was at a 105 BCLK, not bad considering. Since I already knew what the CPU required as far as volts for a 4.9 GHz overclock I typed in the numbers, rebooted and started my stability testing. Then rebooted, reentered the EFI BIOS, and trimmed the voltages down a bit. Pretty simple overclocking this time around.

I did allow the P8P67 motherboard to do an “Auto Overclock”, in the Advanced EFI BIOS for me, just to see if it will give me the same overclock as the P8P67 motherboard did. The auto overclock gave me the same exact results as the EVO motherboard gave me of a 4.5 GHz.

Default Settings that were used

Overclocked Settings

Results

Higher = Better

Starting off with SiSoft Arithmetic testing, it appears the Asus P8P67 motherboard is slightly out performing its bigger bother the P8P67 EVO. I do not think it is enough to be concerned with, SiSoft likes to vary from one benchmark to the next.

Higher = Better

Moving on to the Multimedia portion of testing, The Asus P8P67 motherboard is again performing slightly above the P8P67 EVO. Well at least its nice to see that an affordable motherboard can keep up with a top end motherboard.

Higher = Better

The Memory Bandwidth testing is confirming that the Asus P8P67 is right on par on performance with its bigger brother P8P67 EVO.

Lower = Better Measured in ns

The P8P67 motherboard is definitely giving us some rather consistent performance .

Higher = Better

Starting on the AIDA 64 benchmarks, the P8P67 motherboard is still able to keep up with the P8P67 EVO motherboard.

Lower = Better Measured in ns

Similar to SiSoft memory, the P8P67 motherboard manages to keep giving us consistent performance, and this motherboard shows no signs of letting up.

Higher = Better

I will let the charts speak for themselves, as they say a picture is worth a thousand words.

Measured in Seconds Lower = Better

Turning our attention over to the real world benchmarks, the P8P67 motherboard still out performs its bigger brother, the P8P67 EVO motherboard.

Measured in Seconds Lower = Better

The P8P67 motherboard still keeps its relentless beating to the P8P67 EVO motherboard.

Measured in Seconds Lower = Better

Speechless.

Higher = Better

Well kiddies, what did we learn from all of these tests and charts? That even though the P8P67 motherboard may lack in some features, it sure in hell does not lack in punch. And this little motherboard can, and is more then capable of slugging it out with the best of them.

The Games

This portion of testing is only done with an Asus P8P67 EVO motherboard that is capable of running a 8×8 dual VGA PCI-E lanes, vs the P8P67 motherboard that can only use a 16×4 configuration dual VGA PCI-E lanes. I want to see if there is a truly a difference; these results may surprise you.

Higher = Better

Starting off, one of the most widely used video benchmark out there today, 3DMark11 has become a standard for which we all use to gauge our computers video performance with. For the most part, I cannot tell the difference between the level of performance between the Asus P8P67 motherboard and the P8P67 EVO motherboard, while my two 6970 video cards are in Crossfire mode. Now lets move on to our next test 3DMark Vantage.

Higher = Better

Now we start to see the difference between the P8P67 motherboard and the P8P67 EVO motherboard. Looking at the Crossfire numbers, the EVO motherboard is giving a bit more performance because of the 8×8 PCI-E VGA lanes distribution. Time to move on to Unigine Heaven.

Measured in FPS Higher = Better

Now this is what I expected to see, Nothing wrong with the P8P67 motherboard, just the limited bandwidth on the secondary VGA port is starting to weigh heavily on the performance of the 2 6970 video cards while they are in Crossfire mode. The single video card mode is looking great, in fact the P8P67 motherboard is still showing its supremacy.

Measured in FPS Higher = Better

Ouch, this has got to hurt. The P8P67 motherboard gives us some rather impressive numbers on the single video card configuration. But the limited x4 PCI-E lanes to the secondary 6970 video card is still killing my overall performance.

Measured in FPS Higher = Better

Interesting results, during the 1920 x 1080 resolution testing in crossfire mode, both motherboards performed identical to one another. But, once I kicked up the resolution to a staggering 5760 x 1080, we start to feel the performance crunch of the x16 x4 PCI-E lanes limitation of the P8P67 motherboard.

Ending Thoughts

So what is truly the difference between the P8P67 motherboard to its bigger brother the P8P67 EVO motherboard besides the visual differences? Well if we go off of the CPU performance between these two motherboards, nothing. The P8P67 motherboard clearly was able to keep up with the EVO motherboard in both performance, and in overclock-ability. the only true differences between these two motherboards is the fact that the P8P67 EVO motherboard fully supports an 8×8 PCI-E lanes to both of my 6970 video cards while they were in Crossfire mode, where the P8P67 motherboard uses a different PCI-E lane distribution of a x16 x4 to the Crossfired 6970 video cards. Despite the limitation of the x16 x4 PCI-E lane distribution, the P8P67 motherboard still managed to put up some rather respectable numbers during my Crossfire testing. While some games may feel the crunch of the limited nature of the secondary PCI-E lanes of x4, there will be games that won’t. So your results will vary greatly from one game to another.

The only thing I did not care too much about the usage of the secondary PCI-E port, was once I enabled this port to a x4 configuration, I lost the use of my PCI-E Creative X-FI Fatality Titanium sound card, because it shares (or borrows) these PCI-E lanes from the two single PCI-E x1 ports and the front IO USB 3.0 header (USB 3/4). I feel that Asus could have split the PCI-E lanes evenly across both VGA PCI-E ports.

For more information on our Rating system please visit this post HERE. The P8P67 motherboard did exactly what was stated on both the box, and what was printed in the manual. Looking around the internet this motherboard goes on or around the 140 USD mark, which will fit anyone who is on a tighter budget who needs to have a motherboard that is slimmed down on some of the features, but does not sacrifice on performance. With the pricing of this motherboard, and the core features that Asus keeps in play on this motherboard, even I can overlook the small things.

I give the P8P67 motherboard a well respected and earned:

9 out of Ten and the:
