Hi all,

I post this as I suspect the hardware may be an issue.

I am trying to overclock the i5-2500K on the Asus P8P67 motherboard. There are multiple ways to achieve this, by letting the mobo do it in the EFI BIOS under EZ Mode, or manually doing it in advanced mode, or even in the OS itself, letting the Asus AI Suite do it.

Regardless of how it is overclocked or by how much, Windows ALWAYS hangs at the Windows Loading splash screen. The lights pulse so the whole PC hasn't locked up, but Windows just will not go past it. I have left it for an hour+.

If I go into the motherboard and Load Optimized Defaults, it will load Windows every time. I even tried both stock and overclocked in Safe Mode, and they run through all the same processes to the end of the list. When not overclocked, it continues to boot, when overclocked (even my 100Mhz), it hangs.

I am running:
Asus P8P67 Pro V3 stepping mobo - the Asus update says it has the latest drivers
i5-2500K CPU
G.Skill 1600MHz PC12800 Ripjaws RAM Kit
Windows 7 64-bit Home
Seagate 250GB SATA HDD

Very disappointed so far... wasted many hours watching youtube videos on overclocking this and reading guides, my system just doesn't seem to perform like others.

Any help or advice would be great - this situation sucks.

How're you trying to dial it up? The only thing you should need to touch is the multiplier and the vCore.

I tried three ways.

1. In the BIOS, the EZ Tune software (auto-oc).
2. In the OS, using the ASUS AI suite software (again auto-oc)
3. In the BIOS, reset everything to default (which boots), then just changed the multiplier from the stock of 33 to 34 (left everything else stock) and saved and exited, same thing: Windows hangs at the loading splash screen.

I seem to have figured it out. The Asus AI Suite II software that came with the motherboard was the cause. As soon as I uninstalled it, it stopped hanging at the Windows splash screen. I am now manually overclocked to 4Ghz and Windows boots fine.

Thanks Asus... I knew I should have gone Gigabyte.

Glad you got it figured out. Some of the Asus board utilities cause weird behaviors on my P6X58D-E here. Such as phantom high IMC voltages. Can't see the voltages as being high on any reading, but the temps I can.

Glad you got it figured out.

Thanks, it was driving me crazy. Been running Prime95 for a couple hours now on the stock cooler at 90°C and hasn't missed a beat, so fingers crossed.

The EZ mode high performance option (or whatever it's called) should get you 4.2GHz without breaking a sweat. With very little effort I got mine up to 4.8GHz stable but didn't spot ANY difference in the usual benchmarks or when playing the games that I play, so in the interest of keeping the temperature down in my den I now run at 4.3GHz.
Incidentally, the ASROCK Z68 boards can get this same chip well above 5GHz!

All on the stock cooler?

The CPU was running at 90°C while running Prime95 (peaking at 92°C), so I am not sure I would want to go much higher. EZ Mode set the target to 4.3Ghz but I was not sure that was going to work on the stock cooler so I left it at 4Ghz. It's extremely fast at 4 anyway, I love it. I'm not a serious overclocker, so a little bit of free performance is a bonus.

:cheers

Ah, maybe not then. I bought the OEM chip so I don't know what the stock cooler looks like.

I have tried more than one cooler though, and although the one I have on at the moment is a bit of a monster, it's not as big as some others on the market. None of them appeared to exhibit a clear advantage over the others.

As I said, the extra overclock made very little difference in the benchmarks and games that I ran anyway, so I didn't see the point in stressing the chip until a game came along that needed it. :onethumb
