Overclocking i7 new to me, help!

[SDNYC09]

ok i decided to build a new system im lost with this qpi and ram speeds i have a few questions but let me list the specs first....

i7 975 - thermalright 120
evga 758-a1 x58 mobo\
evga GTX 295
8 gigs 2x 2gig gskill trident 2000mhz ram
2 ssd raid 0
2 raptor raid 0
1000 corshair supply

I have a few questions first

1. why keep the FSB so low? 133 x25? why not say 10x333?
2.Is it this ram messing things up? ALOT of BSOD - will nto post with the xp setup like 2000mhz
3.qpi i set to 6.4 is that right? which in cpuid it says qpi is like 3100mhz - now what cant that go over ?
4. i set the ram to 1600 the qpi 6.4 set the ram speeds correctly still BSOD not even pushing the FSB or CPU


Id like to get 4000 cpu with atleast 1800 on the ram, im just lost on how to get this workign right, im so used to the old intel chips Q9650 - Q6600 where a FSB and some voltage works.

If its solid that the ram is a problem post the best triple channel for my specs ill buy it...

I had a problem overclocking the old AMD chips with the hyper transport BS...i feel this is kinda the same thing.... any help at all or just a learning experience is great


thanks all

If anyone is runningt this mobo and chip what did you do?

Im just not understanding how to figure the ratio's between the ram and qpi with the fsb invovled ...im stupid

Don't worry about the QPI settings, it uses a different multiplier than the CPU frequency multiplier. Whatever it defaults to should be fine and should not inhibit your ability to overclock your CPU.

The only items you should need to adjust to get a nice overclock should be the bclk,, CPU multiplier, CPU voltage, QPI voltage, and memory frequency. Assuming you can get things to run stably at stock speeds try adjusting the following settings:

1. Increase CPU voltage to 1.30
2. Increase QPI voltage to 1.30
3. Increase blck to 167
4. Decrease CPU multiplier to 23
5. Adjust RAM frequency to within limits of your RAM. So that it runs below the highest rating setting.

This should be cake for your CPU and it should have way more headroom. Once you find this stable try bumping the multiplier up by 1 and testing stability. Keep bumping the multiplier up until it is no longer stable. Then lower back to the highest stable multiplier and increase the bclk by 5 and test again. Repeat until failure. Then try adjusting CPU and QPI voltage in small increments and re-testing for stability. Find a reasonable trade off between clock speed and temps and enjoy.
