I am trying to overclock my 4770K Haswell to a half decent clock whilst remaining stable.

I'm currently at 4.5Ghz with Core Voltage at 1.25 but it keeps giving the BSOD after a few minutes running OCCT or Prime95. I've had a quick look at the log file and the offending file seems to be ntoskrnl.exe and nvlddmkm.sys.

I didn't even think going to 4.5 would be such a strain for it. It's starting to get extremely annoying now.

Thanks in advance.

Really?! I swear I read somewhere that anything over 1.25 will make it an unhappy chip. Maybe that's BS then :p

Will knock it up to 1.275 and report back.

Another thing, off topic a bit. I was told that when you have two cards in SLI, it only uses one lot of memory. So I have 2 x 2GB GPU memory, does that equal about 4GB in SLI?

Cheers sir
 
I know you said just use the PC instead of synthetic testing but just wandering around the desktop seems perfectly fine.

I did some OCCT and the issue was it said one of the cores got too hot so it stopped the test. I have an Antec Kuhler 620 with one fan, but come Christmas will have 2 x Corsair SP120 on it.
 
Cheers buddy.

Noob question - what's VRIN voltage? I'm guessing vcore is simply just voltage going to the actual cpu.

Do I need to make any changes to my memory at all? I read some people have fiddled with XMP. Is that recommended?
 
Doing well at 4.5 with 1.275 at the moment.

Quick question. In Valley it says my GPU 1 clock is 1295 Mhz and GPU is 1321 Mhz - any reason why they'd be different?

Exactly the same card.
 
Cheers buddy. Everything has seemed spot on for gaming at 4.5 now - nice and stable. My GPU still needs some time spent on it but I doubt I'll get much out of it as it's the MSI 770 Gaming Edition and I don't think it's meant for overclocking much.

In other news, I found disabling Hyper Threading significantly increases my BF4 stability and has stopped all the random FPS stutters.

Gosh dont tell our friends Setter and Jono that. They claim much better fps and smoothness with the threads turned fully on. Still opinions always vary.

Don't get me wrong, I'm sure it has its benefits in some games but particularly in BF4 when I was experiencing random drops in FPS for a split second I found it totally went when I disabled hyper threading.
 
Mine also runs at 4.5ghz about 65 degrees when on BF4.

Just had a blue screen of death - apparently ntoskrnl.exe caused it. Frankly I have no idea what it is, why it did it or what I can do to fix it. I just lose more patience every time it goes wrong.
 
Just used WhoCrashed and got this...

As you can see from the screenshot below, this ntoskrnl.exe thing seems to be a common issue for me. You can also see how frequently I'm BSOD'ing.
