ASUS P8P67 EVO Conclusion

ASUS P8P67 EVO Details

While not the first motherboard manufacturer to go digital, ASUS incorporates a fully digital power voltage regulator module on all of their P8P67-series motherboards. This new Digital VRM controller is a programmable micro-processor capable of accurately matching multiple PWM signals without power transfer loss. The switch from analog to digital power regulation makes the ASUS P8P67-series motherboard more energy efficient because it reduces total power dissipation, and as a byproduct the components do not create excess heat. With ASUS DIGI+ VRM users can choose between an auto Spread Spectrum mode where the VRM frequency is varied dynamically, resulting in lower interference (dBuV) and higher system stability.

With DIGI+ VRM configured with Fixed Frequency Mode, the motherboard allows for greater overclocking potential as the frequency increases towards 500k Hz (in precise 10k Hz increments). The precision power management allows for longer lasting electronics, better component durability, and a more controlled overclocking environment. Gone are the days when 1.50V meant that your hardware actually received +/- 0.025 volts (or worse), now the requested voltage setting correctly delivers exactly the right amount of power assigned. This becomes especially handy with ASUS Probe II (an AI Suite II component), which allows users to specify exact operating limits for their projects.


Intel neglected to add SuperSpeed USB-3.0 as a natively-supported option to their 6-series motherboards, but ASUS was quick to include support this appropriately-named technology. Demonstrated at the 2010 CES and now sold on retail shelves, file transfer tests proved an impressive 5Gbps signaling rate was possible. Although USB-3.0 devices don't compete with the third-generation SATA 6Gb/s interface in terms of operational file transfers, SuperSpeed USB easily beats bandwidth performance from the older second-generation SATA-3Gb/s controllers. This is precisely why ASUS has incorporated the NEC D720200F1 SuperSpeed USB-3.0 chip on their P8P67 series motherboards.

Another proprietary innovation to the Intel P67-Express platform is the ASUS DIP2 (Dual Intelligent Processors) feature, which integrates two independent control units onto the motherboard. ASUS TPU (TurboV Processing Unit) relieves parts of process-intensive tasks from the CPU and increases overall performance, while ASUS EPU (Energy Processing Unit) reduces power drain from all system components. Each of these features has its own physical switch on the motherboard, but may also be controlled via ASUS AI Suite II software or enabled in the BIOS.

The ASUS TurboV Processing Unit is designed to manage the Sandy Bridge processor, DDR3 system memory, integrated graphics (H67), and various component voltages. There are very few technical details available about the TPU microprocessor, other than what the chip is labeled with: TPU KB37200F. The ASUS EPU chip is labeled DIGI+ VRM EPU ASP1000C-12 (by CHiL Semiconductor Corporation), and although the specifications are a mystery its function is well known. The ASUS P8P67-series Energy Processing Unit actively manages the power phases, and hands off necessary commands to the EPU driver which coordinates functions with ASUS Smart Doctor II to adjust operating frequency and voltage according to the load applied.


All ASUS P8P67-series motherboards offer four DDR3 DIMMs, which support two sets of dual-channel system memory. Installing incompatible memory may cause boot failure, causing the DRAM_LED to light continuously near the MemOK! button. MemOK! determines failsafe settings and improves the chances of system boot-up when they might not be otherwise possible. By holding down this button until the DRAM_LED begins blinking, ASUS MemOK! will begin automatic memory compatibility tuning to help increase the chances of a successful motherboard boot up.

ASUS surrounds the CPU socket with two anodized blue aluminum heatsinks: one to the rear of the motherboard and another directly above the socket. The surface on each heatsink is shaped to cover the tall VRM's (EMC RS1KU A1040), and several low-profile electronics (5030AL/7030AL). There are twelve (vCore) DIGI+ VRM phases plus two (vDRAM/QPI) on the ASUS P8P67 EVO, P8P67 PRO, and P8P67 motherboards, however the ASUS P8P67 Deluxe receives 16+2 and the P8P67 LE model must make do with only 4+1. Although ASUS does not use highly-conductive Polymerized capacitors, the Japanese manufactured SMD solid state capacitors containing a solid organic polymer and lower equivalent series resistance (ESR) will likely outlast the useful life of any ASUS P8P67-series motherboard.


There are a few unsung heroes hiding behind the scenes. The faux-Northbridge heatsink conceals a tiny ICS 9DB403DGLF (Integrated Device Technology) PCI-Express Intel DB400 four-output differential buffer. This cool-running component measure only 9.7mm long by 4.4mm wide and consumes a mere 3.3 volts, which makes the large aluminum heatsink (and heat-pipe cooling) very superfluous. The Intel P67-Express chip rests beneath a much less impressive heatsink, but heat output is rather minimal. The Nuvoton Technology NCT6776F Super I/O chip monitors several critical parameters in PC hardware, including power supply voltages, fan speeds and temperatures.

By default, the integrated PCI-Express controller on all Intel Core i3/i5/i7 Sandy Bridge processors offer 16 shared PCI-Express 2.0 graphics lanes. Intel's P67-Express chip adds another 8 shared PCI-Express lanes, which are used for all other motherboard functions. The ASUS P8P67 EVO can route all 16 lanes from the CPU to any one of three PCIEX16 graphics slots on the motherboard, or it can split them up depending on the number of video cards installed. One video card will get 16 lanes, two cards will get 8 lanes each, and three cards will yield 8/8/4 lane while disabling USB 3.0. The third PCIEX16 slot runs at x1 mode by default for system resource optimization, and shares bandwidth with the PCIe x1_1 slot, PCIe x1_2 slot, ESATA3G & PESATA3G and USB3_34. The ASUS P8P67 Deluxe, EVO, and PRO allow both AMD CrossFireX and NVIDIA SLI configurations while the P8P67 and P8P67 LE enabled CrossFireX only.


Intel's P67 chipset introduces two native SATA 6Gb/s ports for the first time, a feature previously implemented by add-on chip manufacturers. These new ports (colored gray) are a part of the P67-Express chip, and no longer reside on the ICH Southbridge. Intel's SATA revision 3.x storage controller allows performance enthusiasts to enjoy faster top-end bandwidth speeds from capable Solid State Drive storage devices, and supports RAID-0/1/5/10 functionality. ASUS adds an additional two SATA 6Gb/s ports (colored dark blue) by using the Marvell 88SE9120 controller with RAID-1/0 support. Four SATA 3.0 GBB/s ports (colored light blue) are supplied by the P67 chipset and support RAID-0, 1, 5, and 10.

Although not included as a hardware function, the ASUS HyperDuo software creates hybrid storage drive functionality by combining HDD and SSD on P8P67-series motherboards. Additionally, the orientation of all eight SATA ports utilize transverse-mount connections to stem cables outward to the side of the motherboard. This layout works extremely well for all modern video cards, especially those that measure 9.5" or longer that occupy multiple expansion slots.



# No base clock O/CBernardP 2011-01-06 11:44
Very Interesting review, mostly for what more it reveals about Sandy Bridge compromises. You are the first review I see that spells out clearly that base clock can't be overclocked on the K-series CPUs.

But does it matter? With all the clock management feature implemented by Intel, The CPU will almost always be downclocked, or, if under load, be in one state of Turbo or another.

It's hard to imagine a situation where all 4 cores would be running at their nominal base clock.

From previous info about SB, I was thinking that k-Series CPU would allow control over both the base clock and Turbo clocks.

I'm looking forward to see what AMD will do with base and turbo overclocking on Bulldozer.

# Excellent WorkRobert 2011-01-08 12:03
Very complete and comprehensive work, thanks for this. It's surprising to me that the new SB CPUs seem to leave the X58/i7-9xx CPUs so far behind in most benchmarks. Given the relative pricing between the two, the SBs look like a great deal.

One small typo on page 8, in the X58 Test Platform info, the CPU is listed as: "Processor: 2.80GHz Intel Core i7-950 Bloomfield/Nehalem BX80601950". The i7-950 is spec'd by Intel as 3.0GHz, while the i7-930 is 2.80GHz.

The wrong frequency for the 950 was my fault...thanks for pointing it out! It's been updated to the correct 3.06Ghz.

# Mr.David Glasgow 2012-12-26 15:45
Just would like to say I'm not happy that Asus have dropped all support updates for P8P67 EVO MOTHERBOARD I wanted to update my board to allow for Ivy-bridge but thats not happening any-time soon. If anyone can send me a link to I would be grateful.

I just wish to drop in a 3770K into the socket. more to the point.

I cannot find the update on the Asus website.. I have looked twice, plenty of old updates, with no new updates.! the only way is to buy a cheap Z77 Motherboard something like the ASUS Z77 LX-2 which is under 100 quid on Amazon UK. Be better off with a Z77 Board anyways. future proofing, for more i5 CPU's and i7 CPU's.

You must not have looked very hard on the ASUS web site, as the P8P67 EVO's latest BIOS (version 3602, posted Nov. 28), supports all Ivy Bridge CPUs.

Go here: the "Download" tab, and then the "BIOS" link.

To: David Ramsey, thanks for pointing out something I have overlooked, It would have been nicer without the sarcasm. don't you think, like its Xmas "You must not have looked very hard" thats the bit you could have left out shows your immaturity. Thanks all the same, David.!!

# RE: without the sarcasmDavid Ramsey 2012-12-26 16:50
I wouldn't have been sarcastic had you not made a point of accusing ASUS of having "dropped all support" for a product they in fact continue to support. The P8P67 series has been out of production for over a year and ASUS updated the BIOS for it only last month. ASUS makes no money continuing to support a discontinued product; that they routinely do so is why they enjoy the reputation they have among enthusiasts. You need to be more careful when you make accusations like this.

# Do you work for ASUS nope.!!David Glasgow 2012-12-26 16:55
FREEDOM OF SPEECH:, I live in the UK where we have certain liberties, like the freedom of speech, freedom to self expression, the rights to preserve ones point of view, so please don't hit me up, with crap, you don't even work for Asus, or you wouldn't even be on this thread. Even if you did work for Asus you would never speak to a customer (twice) in the way you have spoke to me, you sound more like a Sony Fanboy. "for crying out loud" its your whole attitude mate, it stinks of a 12yr old child, I'm quite good at sizing folks up too, so come at me again like a troll, I will just laugh you off...

# The Asus Z77 Pro BoardsDavid Glasgow 2012-12-26 17:27
Are the Asus Z77 Pro Boards or Deluxe Boards, faster than the Asus P8P67 EVO boards, I have the spare cash and my P67 Evo is close to 2 years old now, well not far away. I only ever Buy asus because of the clever headers for the front case panel. (Which is a nice less fiddly feature).

Not many other manufactures provide the PC front Panel case header Plugs inside the box that makes wiring up the Power, HD, LED, and USB very simple just saves about 20 mins of time messing around.

Thanks to all who contribute, many thanks in Advance... Dave.

# RE: The Asus Z77 Pro BoardsDavid Ramsey 2012-12-26 17:45
I have tested ASUS P67, Z68, and Z77 motherboards. The processor performance is identical on all of them. However, you will see improvements in other areas: for example, the Intel native USB 3.0 performance on Z77 motherboards is typically better than the third party USB 3.0 performance on P68/Z68 motherboards (it depends to some extent on what USB transfer mode you're using).

Apropos of nothing, some of the newer MSI board also include front panel header blocks.

# USB 3.0 performance on Z77David Glasgow 2012-12-26 21:34
I think because as you quite rightly say the Performance is better on the USB 3.0 and perhaps even USB 2.0 as well... if it also means better GPU Performance via PCI-E 3.0 which is far more bandwidth than I presently have - then I will upgrade to the Asus P8PZ77-V-Pro Board @ 140 which seems better value than the other more expensive boards. What's your opinion on the Deluxe Board Z77. I've had a look and its 30 more than the Pro, but cannot see where I would take advantage, as the Asus Z77 Pro has all I need including Extra USB 3.0 / an external plate that comes with the board. any-ways happy new year to you both. (for doing the editorial). Adios...

# RE: USB 3.0 performance on Z77David Ramsey 2012-12-27 04:59
Honestly, the only reason to go for the Z77 boards over your existing P67 board is the extra features provided by the Z77 chipset and whatever fun stuff ASUS has added. The CPU and GPU performance will be identical.

Yeah, the newer motherboards have PCI-E 3.0, but since no graphics card comes close to saturating an x16 PCI-E 2.0 slot, the extra bandwidth doesn't buy you any better GPU performance.

Z77 gets you stuff like Intel Smart Response technology (SSD caching) and other things. Check out some of our Z77 reviews for the details. Again, though, if you're looking for better CPU and GPU performance, the only way to get that is to buy faster CPUs and GPUs.

# Thanks for all yourb Help David & OlinDavid Glasgow 2012-12-27 06:20
David & Olin thanks for all your help I've decided to stick with my present ASUS EVO board and buy a 2700K drop it in while the Price has now dropped in the sales to 199.00 which is fantastic.on one website. I think also I will dig deep and go for the intel 330 SSD 180 GB or Crucial M4 256GB. Like My Evo board you guys reviewed is a decent board and is far from obsolete. I have not a need to buy a GPU as I have a MSI GTX560-Ti I CAN RECYCLE.Though if I had the money I would go for the new GTX660-Ti it can be bought at a latter date. Thanks Guys for your help.
