DFI LP UT X58-T3EH8 - First bench, bios screens etc

Yeah, I've been having issues trying to figure out this combo of vtt/vcore/vdimm. I have the OCZ dual channel ddr3-1800 and it has max 1.95 volts. If I got in and set my memory first, like I always do, my VTT starts going up on its own. Herew's what I get:

vDimm Vtt
1.560 1.21
vtt is same until -
1.740 1.23
1.755 1.24
1.770 1.26
1.785 1.28
1.800 1.29
1.815 1.30
1.830 1.32
1.845 1.34
1.860 1.36
1.875 1.37
1.890 1.39
1.905 1.40
1.920 1.42
1.935 1.44
1.950 1.45

So it seems to be moving vtt in sync with vdimm for stability? I'm getting ready to order an 1866 set and hope I can get 4GHz. I'm stuck at 3.8 right now and think maybe the high vdimm is forcing the vtt too high and is throwing vcore out of whack?

I just put in 0106 BIOS and retesting in hopes of 4GHz.

wish me luck

ps. you may want to shrink those images a little.

Mark that is by design see http://i4memory.com/102537-post3.html

Following the guidelines, for safe high vdimm usage, you need to keep CPU VTT (Uncore) voltage within 0.5v of DRAM memory voltage. Seems the bios has a clever feature, if you try to initially set DRAM memory voltage to >0.5v difference from CPU VTT, the bios will automatically increase CPU VTT voltage to ensure there's always a 0.5v difference between DRAM memory voltage and CPU VTT!

it's so you don't kill your cpu by accidently going beyond 0.5v variance between vdimm and cpu vtt

I just ordered the DFI x58 board from Newegg, should be here Tues Jan 13. I'll be keeping my giga x58 ud5, so I'll be able to do a direct head to head shootout with same components, same Vcore so I'll report which board OCs better. I'll be glad to run any experiments on a request basis, just let me know.

nice, let us know how it goes

Just love the front of this box ... and what's inside as well

Sweet AK, mind those image sizes though and don't forget to share your results once you get the hang of the board = http://i4memory.com/f80/share-your-d...ts-here-13273/
