Over clocking 950 i7

Redbull8447 · 28 Dec 2011 at 14:34

Hi guys

Need some help

got the following

ASUS P6X58D-E Motherboard
Intel i7 950 CPU
Venom cooler
24gb Corsair Vengeance 12GB (3x4GB) DDR3 PC3-12800C9 1600MHz Ram
asus 5870 GPU

Currently have system running at 4ghz but the ram is only running at 600mhz

has anyone got some setting i could try to get the best out of my system

currently got multiplier and clk @ 20x200 ram in auto as dont quite know what setting to use

thanks in advance

Hi, have a look at this thread, scroll down to my post, l'v put the Bios settings for a i7 920 at 4,0GHz, use them as a rough guide -

24gb may have an impact on any overclock, as it puts quite a strain on the memory controller.

Yes, Setter has a good point. You'll probably want a lot of VTT voltage for that, and that will mean a lot of heat. I'm running 24Gb RAM at 1600MHz and my mainboard is watercooled as otherwise it just wouldn't cope.

1. Run some benchmarks.
2. Note down the results.
3. Change RAM multiplier to x8*.
4. Run benchmarks again.
5. Note down the results.
6. Change BCLK to 21*.
7. Run benchmarks again.
8. Note down the results.

*If at any time the system becomes unstable, you will need to find an overclocking guide (which there are lots of) and do it properly (which should be done anyway).

Decent guide here,

http://www.overclock.net/t/538439/guide-to-overclocking-the-core-i7-920-or-930-to-4-0ghz

I found that 20x200 bclk required a bit more vcore and vtt than 21x193, at that time i was running 6gb of ocz reaper 1600mhz, (7-7-7-24). Ive since swapped them out for 12gb of kingston hx in a 3x4 config. Had the cpu at 4.2ghz for a while at 21x200, but ive knocked it back to 4ghz.

What about activating XMP in the BIOS? RAM is good enough in nearly any system when at 1600, right?

Ive never used any xmp modules myself, but from what ive seen, it can often set qpi/vtt voltage rather high, much higher than may be needed using manual tweaking. This adds to higher temps.
