So I'm trying to overclock my system and I'm a complete newbie at OCing. I've tried several configurations and here is my latest one. It's very unstable and I get Blue Screen of Deaths every few minutes without even doing anything intensive, and I'm wondering what I'm doing wrong. Had to reset to optimized defaults to be able to post here.

My system is in my sig, but the two important things are i7 930 with a GA-x58a-UD3R rev2.0 mobo

The screenshot was taken when, in the BIOS, it was still set to 1.19375V as far as I could tell, or perhaps it was set to [AUTO] at the time. I'm forgot.

Should drop your QPI ratio to the lowest possible setting to make sure you're not pushing the bus too far.

Isolate the problem. Run PRIME95 blend and small fft. If you crash, or if quick errors pop up during blend, it's almost certainly the RAM (your 8-8-8-(20!!!!!) timing struck me as extremely tight and has high potential for being the culprit). Timings are usually 8-8-8-24. BSOD strongly suggests RAM to me...general system instability is usually linked to RAM.

Beyond that, lower multi to 20, BLCK to 180, start at 3.6 and work up. You can likely establish stability at 1.25v if you work at it.

Your memory multiplier is at 6x. Uncore multi you have set at 20x. Uncore multi should be 2x memory or at best 2x +2. So try uncore multis of 12, 13, and 14.

^ yes, you don't gain much apart from instability by overclocking the QPI.
I haven't touched my QPI ratio and my Uncore multiplier. Left them at auto. I should lower them I guess?

RAM is also at default. Not sure if I can change the timing to 24. And 1.25V is Vcore or VTT after lower multi to 20 and BLCK to 180?

You absolutely can change the RAM timings...can you link me to your particular RAM? EDIT: NM. http://www.newegg.com/Product/Product.aspx?Item=N82E16820145220&Tpk=TR3X6G1333C9

As I suspected, your timings should actually be 9-9-9-24.

1.25v is VCore. Lower multi to 20, BLCK to 180 (could go even lower just to establish stability). However, once you input these settings, you need to get PRIME 95 and establish where the problem is - blend test, small fft test, or both. Have you used PRIME95 yet? It's a good way to find instability.

Yes, change them from AUTO to get a lower value. The AUTO value assumes you still have default BCLK.

Check these:
Lower Uncore to lowest multiplier (most likely candidate)
Add a little bit more core voltage and disable LLC (since you are crashing without stressing)
Add a little more DRAM voltage (to make sure your memory isn't causing it)

Should I change the timingts manually to 9-9-9-24 then? As for PRIME95, yes I've been using it as well. I use custom testing and set everything to as big as possible. things used to be stable even through 10 minuets of testing but I tried changing more values and things got wierd. I dunno. I think I was mixing up VTT voltage and Vcore voltage in the past, which was why I kept raising VTT. At one point my VTT was at 1.495V. But now I'm re-reading the guide and will hopefully have better luck when I get home from work. When I use Prime95, if I get errors how do I know where the problem is?
Yes, change them from AUTO to get a lower value. The AUTO value assumes you still have default BCLK.
The For QPI ratio, Auto setting also seems to equal the lowest setting which is x36, which is what I'm already at, so I'll leave it at that. For the Uncore, I will try lowering it manually to about 2x my RAM SPD multiplier.

Check these:
Lower Uncore to lowest multiplier (most likely candidate)
Add a little bit more core voltage and disable LLC (since you are crashing without stressing)
Add a little more DRAM voltage (to make sure your memory isn't causing it)
What is LLC? And how much DRAM voltage to increase?

I don't see those two lines in my BIOS. I'll look again after work. I presume that in those values, the left values are default and the right values are what you want me to set them at to test?

Why? :'( I actually have this: http://www.newegg.com/Product/Produc...-029-_-Product It's called the Kuhler Box from Antec.

EDIT: Also, hyperthreading = terribad?

Yeah I had to pull those lines from another board, they might be gone from yours. Just skip if so.

As to HSF: The default intel heatsink is atrocious, so if you were overclocking to 4.0 using that, the chip would just get too hot. You...do have a fan on the heatsink, yeah??

The Kuhler box has TWO fans as far as I know. It is a pretty kickass cooler.

Noe back home and running Prime95 using settings similar to what you've posted Axon. Should I also use IntelBurn Test?

One thing is strange. I still can't get my CPU core voltage in CPU-Z to match what I've inputed in BIOS, although they are genreally not too far apart. But in these setting a 0.1 or 0.2 difference can be a lot.

Will report errors.

180 x18 multiplier stable after 6 mins of Prime95 testing, although not sure which tests to do. I just cranked everything up.

Sounds good. Intel burn test and LINX are also good options. Just to advise you on PRIME95, when you first open it, it says something like "just stress testing," then it asks you to choose between three types of test: Blend, SmallFFT, or LargeFFT. Blend tests some CPU and a lot of RAM, while Large and Small FFT focus more on CPU. So if you fail Blend but pass FFT, you're likely looking at a RAM issue. Conversely, if you fail blend and a FFT test, its probably the CPU's voltage or something.

Voltage issue...go into power settings in Windows and set it to performance. Windows button, search "power options" in the little bar there, and reveal the "performance" power plan under other plans.

The way I cranked things up, 100% of my CPU is being used (all 8 threads) and 70% of my RAM is being tested.

I just ran 20 minutes of Prime95 at 200 mhz x19 Multiplier. Stabile so far! Will now restart to try x20 which will be at 4 ghz.

Hyperthreading is still on. Is that a bad thing?

Nah, HT just causes more heat, maybe a little instability. Good to hear that its stable. It should work out perfectly now...RAM timings/QPI/UNCORE are almost always the culprit.

I think it was the Uncore multiplier. It was at 20. Now at 14, and I'm steady after 35 minutes of Prime95 at 200 x20!! ^_^

Will post new settings here in a little while. Should I try to go higher I wonder? Right now, after 35 mins of Prime95, my CPU is at 80C under full load...and I'm browsing the web at the same time!

Just for kicks, I'm upping my CPU multiplier to x21 just to see if my system will be stable, but I'm happy with my 4.00 ghz OC off of air cooling for now. Temperature idles at around 40C.

EDIT: 200 x21 @ 4.2 ghz did NOT pass IntelBurn Test. I got a BSOD a few minutes in with Stress Level at Very High. Reverting to 200 x20 @4.0 ghz and re-running the test. I wonder if it was my RAM voltage or my Vcore or my VTT that needs to be increased...

EDIT 2: 200 x20 passed. 200 x21 with the Vcore raised to about 1.3250V also passed IntelBurn. Guess I'll try that for a while.
