UnOfficial EVGA X58 Classified Owners Thread

So you made sure 4GHz Uncore are stable, you can now tell what vtt is needed the least.

I would say you set the memory to xmp in bios and watch the timings being set in memory menu. DO NOT let it use xmp though as it sets Vtt way too high. You may be able to just change voltages using xmp, but i am not sure. Use xmp timings, +175 Vtt, 1.63-1.64V Vdimm - depends on what you get from overvolting vdimm circuits (eleet is a good indicator for vdimm and relativley spot-on). You should not go over 1.65V real vdimm first, as specs and binning from corsair are being "conservative" imho. There's often much more in those GT sticks. Don't forget to set the ram multiplier to 10x manually. xmp may set it to 14x.

BTW, you may need one or two notches more vcore with this kind of imc stress.

Yup earlier prime95 crashed BSOD 0x0000003B. I had to increase vcore 1 notch. Running in for 2 hours now. I'm just gonna let it run for another 15 mins before running xmp with edited voltages and ram multi as how u advised. Will edit this post with results.. if it crashes, does it mean I can rule out lack of vtt as the reason?

edit: xmp sets trfc to 110. shouldn't it be 88 for c8?
edit: yeah I'm testing with xmp first. looks good so far. I set vdimm to 1.63. e-leet reading is 1.69. Is there anyway to open 2x e-leet windows?
Probably the reason I'm pulling my hair for a week is because if trfc settings being set to 88 and the rig refuses to stay stable for 2 hour prime 5.4gb runs.
edit: Prime95 froze @ 7th test. increasing vcore 1 notch and rerunning it. increasing vcore 1 notch caused it to crash at 2nd test. backed down vcore 1 notch now and increased vdimm to 1.64v.. prime95 restarted.. its looking like its the same as when I'm running trfc 88..sigh. Now trying vcore up 2 notchs and vdimm at 1.64v. prime froze again after 3 tests.
