If you're sure you'll never want to overclock or use dual graphics cards, then yes it's a perfectly reasonable option.

Oh. No amount of overclocking is possible on the H67? Wow then it's basic as gently caress and while cheap it's probably overpriced anyway.

No amount of CPU overclocking, anyways. It's pretty much perfect for OEM builders of consumer and business desktops though.

How far have people gotten their 2500Ks in terms of OCs?

I'm running at 4.65GHz at 1.35 Vcore via a CoolerMaster Ultra 212+ on the el-cheapo Gigabyte P67A-UD3. It boots into Windows at 5 GHz on 1.4 Vcore, but crashes immediately afterwards. I don't think it's safe to bump the Vcore any higher, sigh.

This is the exact combination of CPU, mobo and Heatsink I just ordered, with approximately the results I was hoping for.


This fellow seems to think that the cpu has a bit more leeway as far as voltage goes, though I don't think I'd ever go to 1.5V.
http://www.overclock.net/intel-cpus/908782-sneak-peak-my-sandy-bridge-overclocking.html

But 1.4 should be plenty safe 24/7 by the sounds of it. Have you managed to get a bit under 5 GHz stable on 1.4V?


Also, what kind of temperatures are you getting?

I will go back to water-cooling if my particular CPU can sit around 5GHz stable @ <= 1.425V or so. That's just too much e-peen to give up.

How does the P67 UD3 compare to the UD4?

I read UD3 doesn't seem to be ideal for sli/crossfire and doesn't overclock as well as an UD4. Does this means anything for the "enthusiast" who will just do some mild overclocking? What do you consider would be the 2500k sweet spot between the two?

It isn't ideal for SLI since one of the PCI-e slots is x16 and the other only x4 (whereas the video card needs x8 minimum, or x16 ideally).

Where did you read it doesn't overclock as well?

You should be a-ok, Windows 7 (and Vista) are hilariously tolerant of hardware changes. Might just have to reactivate. My Vista installed lived through 3 different chipsets before I upgraded to Win7. (650i, 680i, P45)

@Paino - terrible for SLI since they didn't split the lanes from the CPU. I dislike Gigabyte, but that board seems to be a solid choice for single-GPU, no deluxe-features needed type computing.

Thought so. My idea is to put a gtx 570 in it and then, in a poor attempt at future proofing, buying a second one for the SLI when it gets cheaper. However this implies overclocking the cpu a bit, buying an additional fan, upgrading to a better, at least 850w PSU.

Does this even make sense or I'd be wasting money?

I've board swapped a few dozen Windows 7 systems, at worst I've had a blue screen on bootup, one reboot later it switches to default drivers and it was running again. I don't know about BIOS to EFI but I can't imagine it would matter as they just need to run the boot loader.

What resolution do you game at? If you plan to do SLI in the future, definitely get a board that will amenable to it (i.e. 2 x8 Gen 2 lanes split off the CPU).

1920x1080, but I want ultra details everywhere and consistently high FPS. I wonder if, by putting a gtx570 in a lower pci slot and buying a P67 UD4 plus an 800-850w PSU, I'd already be set for a second 570 in, say, 1-2 years to keep the rig in solid shape.

Obviously I'm not on a tight budget but I still would like some value for my money: again, does the above make sense?

Yes; you are increasing multi and therefore increasing clock frequency, and if you bump VCore for stability, you are sucking down more power (P = IV).

The power-saving features will still function (probably), i.e. SpeedStep and such, but yeah, you're drawing more power.

Right now, I have:

4.75 GHz (101.1 BCLK * 47)
VCore 1.37V in BIOS, 1.358 actual idle, 1.31 load
QPI/Vtt 1.14V
System Agent 1.155V
PLL 1.88V

Temps at 100% 60 C measured by the motherboard utility, 61/68/68/69 C measured by CoreTemp.

Stable on OCCT for 2 hours now. If this stays stable, gonna try for 4.8 GHz at 1.38V. Not going to go higher than 1.385 V in the bios (which should equate to 1.375 V actual idle and 1.33 V load).

Sigh... my dreams of 5.0 GHz... dashed. Oh well, not going to complain. It was $280 total at MC for the CPU + Mobo. This, plus the 2 5870s I got a month ago for $300 total, should last me a while.

The only real complaint I have about the Gigabyte P67A-UD3 is that the PCIE slots are split 16x/4x, which is not optimal for Crossfile. But according to http://www.techpowerup.com/reviews/AMD/HD_5870_PCI-Express_Scaling/25.html , at 2560x1600, 8x/8x gives 98%/98% percent relative performance, while 16x/4x gives 100%/95%. I guess 4x PCIE 2.0 is good enough.

I don't know how it works on Sandy Bridge, but with C2Ds and such it clocks down to some pre-set multiplier values. Since the FSB would be overclocked, your lowest power state would be running faster, because now you would end up with some multiplier times a higher frontside bus clock.

I would think on SNB since mults are entirely unlocked, your lowest power state would remain the same regardless.

Now-former CEO Dirk Meyer has resigned in what the company is a calling a "mutual agreement" between him and the Board of Directors. Interim CEO will be CFO Thomas Seifert, who has asked not to be considered as a candidate for the next chief. A search committee for the next CEO is currently being led by Board Chairman Bruce Claflin. The circumstances behind Meyer's departure remain a mystery, but something tells us they can't be as ridiculous as the last major CEO resignation we saw around these parts.

They got it wrong with the original article. It enables QuickSync when the integrated graphics card is not being used. It explicitly does not work with P67 chipsets:

The Article posted:

The news would be better if this software could tap into the Sandy Bridge IGP on a P67 board, but Lucid tells us that's not possible. (An earlier version of this story suggested P67 support was possible. Apologies for the error.)

Basically, Lucid is just copying the framebuffer from the discrete GPU into the integrated SNB GPU, and then having it pipe it out from there. If the chipset doesn't enable the integrated GPU, it's not possible to use it in this fashion.

I've been framed!
Ugh, what a hectic upgrade to a Core i5 2500K and Asus P8P67 Pro. After upgrading, I started the computer back up, and Windows 7 x64 still worked. A little later, I put the computer into hibernate mode, and when I later turned it back on, it gave me a DRAM error and wouldn't start up. I turned the computer off completely and back on, and set my DDR3-1600 G.Skill memory to DDR3-1333, thinking that might fix it, and went back to using it.

Next time I started up CPU-Z 1.56, I saw that the BCLK (Bus Speed), which was usually locked at 100.3 Mhz, was fluctuating wildly from 79-97mhz. 79mhz here, 88mhz there, 81mhz, 95mhz, 79mhz, 97mhz, etc. Scary. Then I installed the very latest version of CPU-Z, 1.56.1, and it reported a solid 100.3mhz bus speed again. Phew.

I updated the BIOS to the latest non-beta version, 1003. In the Asus AI Suite, which is a system monitoring tool, at one point the tool freaked out and reported that my motherboard temperature had gone from 31C to -60C. A restart resulted in it reporting the correct temperature again. Another time, it reported that the 3.3V rail had dropped to 0.03V. A few seconds later it went back to normal.

Have I got a bad board? Are early BIOS versions and utilities causing me to jump at shadows?

I bumped the multiplier to 42 (i.e. 4.2 GHz) and left the core voltage on "Auto," and SpeedStep definitely still works. It clocks down to 1.6 GHz per core and cuts ~.15V off vCore.
