ASUS P8P67 EVO Conclusion

ASUS P8P67 EVO Overclocking

The Intel P67 Express chipset brings major changes to the overclocking process. Here are the bullet points:

  • Overclocking by increasing the base clock is no longer an option.
  • Overclocking by increasing the CPU's base multiplier is no longer an option.
  • According to Intel, the P67 Express chipset is the only Cougar Point chipset that supports processor core overclocking at all.

Overclocking by raising the motherboard's base clock is now all but impossible. On the ASUS P8P67 EVO motherboard, the highest increase to the 100MHz base clock that I could get to run through stress testing was...103MHz. This limited overclocking ability is apparently because the P67's base clock is used to derive almost every other clock in the system, including the SATA and USB clocks. While having a single clock be the base for every other clock in the system probably means cheaper, more reliable motherboards, it removes an overclocking mechanism enthusiasts have used for many years.

Intel compensates for this by giving all Sandy Bridge processors unlocked multipliers: K-series processors get "fully unlocked" multipliers with no limits, while non-K series processors are "limited unlocked" CPUs that can only have their multipliers increased by a maximum of 4. All Sandy Bridge processors have fully unlocked video cores, RAM multipliers, and power settings. Notice, however, that you can only use and overclock the integrated graphics core on a motherboard with the H67 Express chipset, and only overclock CPU cores, power, and memory ratios on a motherboard based on the P67 Express chipset.

Overclocking Sandy Bridge CPUs is different in another way, too. While everyone has their own overclocking techniques, I generally like to disable "turbo" features and run all processor cores as fast as I can under stress by raising the base multiplier. Well, you can't do this with the Intel Core i7-2600K: in fact, you can't increase the base multiplier at all! I suspect this limitation is built into either the processor or the P67 chipset. Your only option is to increase the multiplier that will be used by Turbo Boost, and you can set individual multipliers to be used when 1, 2, 3, or all 4 cores are in use. Thus, if you disable Turbo Boost technology, you can't overclock the processor at all.

This image shows the "AI Tweaker" section of the ASUS P8P67 EVO BIOS. The base clock frequency is set to 102Mhz in this screen shot, and the "Turbo Ratio" selection is set to "By All Cores...", which means the multiplier specified below will be used when any or all of the CPU cores are in Turbo Boost. This mode also allows you to adjust the multiplier using ASUS' "Turbo V EVO" utility on the fly in Windows; alternatively, you can select to adjust the mutliplier used when 1, 2, 3, or all 4 cores are separately active, but this can only be set in the BIOS. With a base clock of 103Mhz and a multiplier of 46, the Turbo Boost clock speed for all cores was 4.738Ghz. The CPU voltage for this overclock was 1.225 volts, although it's shown as 1.152V in this CPUID screen shot. Intel aggressively throttles both the CPU clock and voltage whenever possible.

I did try ASUS' Turbo V EVO auto-overclocking feature. Set to "Extreme", it eventually settled on a base clock of 104.6Mhz with a multiplier of 43, for a final clock speed of 4.497Ghz. The auto-overclocking utility apparently will not attempt to adjust the core voltage, which limits the overclocks it can reach. Still, it achieved a nice overclock with virtually no effort. But to wring the maximum performance out of this processor and motherboard, you'd need to spend some time (probably days) finding the highest possible multiplier for the number of cores in use (1, 2, 3, or 4).

# 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: ##asus.com/Motherboards/Intel_Socket_1155/P8P67_EVO/#download

...click 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...

Thank-you Olin, Merry Xmas... for sorting the matter out I was never looking a Beef with no one, all of a sudden this guy, I don't even know nor doesn't even work for Asus, hits me up with "Hard Talk"... as if he was 'God and he happens to be above me', which is certainly not in the spirit of this forum, nor the spirit of Xmas... I consider the matter closed, Thanks Olin.

# 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.
