Where's the record breaker on this thread? No one yet? Man...I'm disappointed.

**cstkl1** · 06-11-2009, 07:09 AM

gunslinger ure vtt is 1.35 not 1.1

and fallwind

vtt min on any board is 1.2
so get ure voltage right with screenshots for vtt with ure gigabyte program.

**Sam_oslo** · 06-11-2009, 07:59 AM

My result has been recorded in the databse aleready, but without VVT, it is: 1.24v. A new run, this time Prime Blend on the same setup.

I must be imagining this then?

Sorry, it's 1.16, not 1.15. It was 4am so I'll blame lack of sleep!

One thing I noticed with the 2 Gigabyte boards I've had, higher VTT actually reduced stability. They ran best with VTT as low as possible.

Please don't forget to include also a screenshot with the qpi/vtt values.

this is just awsome for water expecially for florida you mush have the ac kicking
also what model of the classified do you have?

Thanks, I have the 760, the one w/out NF200. Yea it's kinda tough in florida ambients are always real high and AC not usually kicking because in order to cool the computer room the whole rest of the house reaches freezing cold temps and everyone complains lol. It's just lot's of tweaking to try and get the best temps. I think I can get it higher but taking a break for a bit, the 4.5is nice because everything still works properly including sleep mode. Gonna go for 4.6 next!

**cstkl1** · 06-13-2009, 10:12 PM

interesting fallwind.

hmm testing a evga 760..

found out that the eleet voltage and everest read voltage is way different
eleet is just a bios setting voltage. not a read voltage.

interesting to see how much difference with a dmm.

also found the trick to bring down my vcore for 4.2ghz back to 1.25v.
and now testing 4.3ghz 2050 C7 ,4.4ghz 2100 C7, 4.5ghz 2150 C8

**~~bluehaze~~** · 06-14-2009, 08:11 AM

Hey Bill, you got my QPI/VTT and CPU volts mixed up there. And also the 4.5 was with regular Corsair Dominator 1600mhz. My Dominator GT's bit the dust...second set of them to die in 3 weeks. I think I might just stick with the regular Dominators until something more reliable comes out.

Thanks

A trick for bringing down vcore? Do tell, my step up from 19x210 to 20x210 is kinda... ugly.

50 passes of LinX:

I'll have to dig up my 4.51Ghz LinX/Prime stable screenshots whenever I have a chance.

**ben805** · 06-16-2009, 05:53 PM

For those who run LinX, may I ask why didn't you use up all the available ram for the stress test? I saw someone also had 12GB of ram but in linx he only tested with 1GB?? LOL max out that sh1t and let it rip yo!

Nice chip you got there! is your OC stable in LinX as well?

Thanks. Yep, I usually start with Linx to get in the ballpark and it's rather predictable...3 different processors and 2 different sets of ram always 2 notches up on vcore to get Prime blend stable after Linx.

Linx is rough regarding temps but is easy as far as stability goes about the same as Prime Small FFT's.

mine also behave like yours....needed to bump up a few notches for prime after linx.

Need moar fans! 3 is not enough for my rad

This is best I can do with 1600mhz ram...maybe can do more if I get some 1866 and 3 more fans for my rad to do push pull but taking a break for awhile!

The chip still could do better but anything above 1.4v Vcpu and turbo throttling starts. Multi drops from 21 to 20.
I don't understand why ASUS hasn't fixed it already
