Please help me O/C i7 950.

post #1 of 22
Thread Starter 
Looking for help, with voltages, Ive done a bit of playing around with the presets in my bios, But they seem to crash or be unstable.

I understand a bit, like multipliers.

Im hoping to O/C to 4.2ghz, Stable.

That I would be happy with biggrin.gif

So can people give me suggestions, to help me step by step to finding a nice Vcore, Multiplier, and clock?

I have prime95, memtest etc.

And have read about overclocking, but would like step by step support, if thats not asking to much, because I learn better, from talking, asking questions and getting answers, than I do from reading, If that is ok (:


So, can anyone suggest where to start??

ASrock Extreme3 x58
Hynix 1333mhz triple channel 6gb, timings 8-8-8-24

4.14Ghz STABLE.

To get better answers, post a little bit more info wink.gif

What voltages did you put in place for your CPU, DRAM, etc. IIRC for a 950 to get 4.2ghz you'll likely need to have a CPU voltage at around1.4V. You'll want the bclck at 200 and the multiplier set to 21 of course.

Info, info, info!

Also, if you haven't already read this, chadamir has a good guide here.

Uhh, I used the "ez Overclock"

Setup, that had it at 1.27 for 4ghz, which is why im guessing it crashed.

So My guess is I need to O/C manually, but im not to keen on just chucking numbers and hoping for the best, and burning out a 500$ cpu (Cost in my country)

I shall boot up and get numbers from the bios!!!

Nah mate, don't be afraid of that. As long as you go with accepted voltages, your definitely not going to "burn out a $500 cpu."

Ok, I know bugger all, so sorry if I post irrelevant Info.

Overclock mode..
BCLK FREq (mhz) -133
PCIE FREq (mhz) - 100

Boot failure guard enabled
Boot failure guard count - 3
Spread spectrum - auto

Current Setting 0 23-6.400GT-3200mhzddr3_1600
CPU ratio = AUTO
QPI - AUTO
Uncoe - AUTO
dram - 800mhz / ddr3_1600
(dram timing... Current setting -9-9-24-74-10-5-4-5-24


IES - enabled

CPU voltage - auto
Dram voltage - auto
IOh voltage - auto
VTT voltage - auto
ICH voltage - auto
IOH CSi voltage - auto
IOH/ISH PCIE voltage - auto
CPU PLL - auto

Thats the OC tweaker page, all the information on it.

Ive reset EVERYTHING to stock, because im hoping for you kind kind people to slowly help me O/C, up and up, finding stable levels and guiding me through, so I can understand better, + improve my setup (:

I only changed frequency of my ram (:

Take the blck to 200.

Change that CPU voltage from auto to 1.3V and see what happens. DRAM Bus to 1.65. CPU PLL to 1.81V (maybe a little higher depending). IOH and ICH to 1.2V. QPI/uncore to 1.35V.

Current Setting 23-6.400GT-3200mhzddr3_1600

The 23 in my current setting indicates a multiplier of 23 , 6.400Gt (duno what that is)

3200mhz Current clock, and ddr3 at 1600 mhz

(im assuming those numbers correspond to those places)
