Yeah, I'm luvin it. Du du du du doo.... hehe.

Bad luck on the RAM, hope you get it fixed at little money and hope to see you back in the comp later, it runs for a long period so if finances allow etc you will still be in with a shout.

More mods done:


I also found a voltage source of ~2v that goes to the GPU core, ill do some more testing to see if increasing it will help my overclock

[zakelwe]

Nice work ! Is that brown cylinder a very small tank of LN2? N20?

Good luck!

Andy: sorry i didn't used orb before, so its a noob question, but at my testXP lan is disabled, i could only make orb at online??

Does anyone know if it's possible to loosen ram timings on the cards within the BIOS? My ram is limited to sub 880MHz which is really cramping my style.

couldnt you use Nibitor and tweak the timings?

What are the markings on that chip right next to the D-Sub out? and a better pic of that area would be nice.

[MuffinFlavored]

What cooling is this under?

here are the marking:

ST 3
HI D70N0
21
6K292719

and a better pic (actually not the best if it's till no good i try to make more better, but thanks for help!)

What cooling is this under?

the GS has still the stock heatsink with a 9cm fan, and cpu is custom D-Tek watercooled

Hi, I'm getting my XFX early this comming week, i have been looking for the voltmod on XFX and found this link. Does anyone have the XFX now and is this it...

Warning: Not sure if this is correct but if it is, here we gooooooo.
Hopefully XFX vmod...

WRONG!

EDIT: these are markings on the MOSFET not on the chip. What interests us is that chip:

sorry, you're right, mosfet not chip but that is next to the s-vga out

Never done anything serious with GPUs, I was strictly a CPU bencher in the past. Thanks for that app, downloaded and maybe later today I'll try to loosen some timings. Hope I don't brick my card

save the run
and then upload when you have internet on it by starting futuremark bench and right click on it and upload
