First OC 4.0 stable, Any Tips?

[deckrom]

I ran a 14 hour Prime95 test and got no errors with these settings. I am running the latest MB bios and drivers with Windows 7 Ultimate SP1. I have one 2705RPM Rexus Panaflo fan pushing 100% on my Hyper 212+. I have included my bios settings so please suggest any improvements I can make.

Hey deckrom, welcome to the Anandtech forums!

 

[Kenmitch]

Welcome

I've never played with a 930....But if I did it would be with HT, speedstep,C1E, turbo, etc enabled. I know the guides say to disable them but most chips won't have an issue running with them enabled.

Tip: leave the side computer case door off to keep it running cooler.

What is the "latest" bios you are using? I think there is an 082 bios out.. that's what I am using.

 

[deckrom]

Yeah I'm using the 82 bios release. I'm trying to squeeze out a 4.1 right now.

welcome to the forums!

looking pretty good on that oc. i see the vcore is pretty low for 4.0 which means you probably have a good chip. dont be afraid to jack up the voltage if your thermals allow.

welcome to the 4.0 club!

the next thing i would work on is maybe trying to run more aggressive dram timings. on the memory considering its running 1066mhz.

Doesn't upping the Host Clock change the Target Memory Frequency so that my RAM would be running at 1530Mhz with my bios setup?

i assumed it locked it since it didnt reflect the actual speed.

1530MHz cas8 triple channel, thats a lot of bandwidth and pretty good latency.

I guess EVGA bios templates don't show the actual frequency but on the bios screen its labeled Target Memory Frequency.
My VTT voltage is at +100, reading around seems like most people have it at +200. Should I change mine to +200 or just leave it if its stable & running well?

 

[Spikesoldier]

leave it if its running well.

i think you need more vcore to go higher. and to push high voltages, you need a better cooler.
in regards to vtt, up it after you add vcore when added vcore alone is unsuccessful.
another reason to up vtt is also to stabilize an unstable run that appears stable but is not.

i wouldnt exceed 1.45vcore on air or 1.40vtt at all.

also i believe that a 930@4.0 at 1.27v is pretty good and isnt that bad on thermals.

Yeah I don't think I'll push my luck. Thanks for the help.

If you want to know whether it's really stable I'd suggest testing with Intel Burn Test or another Linpack-based program. This will find instabilities more rigorously and quickly than Prime. 1.27v seems low for 4GHz Nehalem.
