Hey guys here is my setup

i7920 D0 , with thermalright extreme 120
asus p6t delex v2 ,with newest bios
CORSAIR DOMINATOR 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
with xmp profile enabled

My goals
1. do a minor over clock to 3.2ghz
2.keep ram at around 1600mhz and to stay stable , because when i trying just setting the timings 8-8-8-24 and inrease the volt , i would get bluescreens time to time.

Ever since xmp was enabled i have had none.

But from what i understand when i do overclock the cpu host freq , it will also jack up the memory speed , and if i have xmp enabled it will over ovcerclock it ?

sorry for the bad lingo but im really new to overclocking and trying to find the best answer.

Also do you think to achive 3.2 will need to change anything from uncore multiplier , or even QPI link speed ?

Set your Bclk to 166, and then pick a memory speed that works (ie: as close to 1600 without going over).

You will have different memory speed options, depending on what your Bclk (Base Clock) is set at. I'm not sure off the top of my head what options you'll have at 166 Bclk (166 x20 = 3.3ghz)

A 920 D0 should do that effortlessly. What cooling do you have?

Thermalright Ultra-120 eXtreme , my max temps in the cores at full load are 54c


so should i keep xmp enabled or disable it ?

You shouldn't have any problems with cooling then.

I'd try it without XMP first and make sure that the CPU is 100% stable at that speed, and then work on the memory.

160 Bclk might actually work out better for you (at least for starters) because you can use the 5x memory multiplier to run your memory in spec (160 x5 = DDR3-1600). Running 166 Bclk will overclock your memory slightly.

ok so i set my bclk to 160 and ran prime 95 for a about 7-8 until temps were constant .

this is a screen shot of them i think they are too high.Now im worried that i should just stay at default clock


my dram volt is 1.64v , my qpi/dram core volt is 1.35v , i set it to that since xmp profile set it to that.
everything else is set to Auto except for my timings and command rate , 8-8-8-24 CR-2n, and im running the ram at 1600 mhz or what ever it was closest to

i stopped the test thinking that my temps were too high .


Let me know what ya think ,thanks !

Personally I don't worry about temps 'til they get up towards 80C, especially when running stress tests since you generally won't see those kinds of loads on a day to day basis.

But it's your system so don't do anything you're not comfortable with.
