Ok I am going to buy an OCZ Powerstream 520W PSU so I can adjust those rails which my DFI UT 250GB & mushie BH-6 will love... 3.8V on the 3.3v rail should give me up to 3.7vDIMM on the RAM, that is without ANY vmods, DDR boosters etc. :cool:
but will it damage my mobo or any other components? I am planning on running it @ this voltage all the time. Will it cause a catastrophic meltdown? :confused:
I have done this with my DFI 250gb + OCZ520W and it gave me 3.75v on the 3.3v, and 3.55v effectively in the BIOS. Highly unscientific reading on POS sensors from DFI mobo, however :D

so can you run this voltage all day long without problems? I asked OCZ tech support and they didn't recommend it

i think bowman said something about it... iirc he had the 3.3v rail at 3.8v wich resulted in the vio voltage going to high wich killed 3 of his a64 cpus...
but that was with a first generation 939 board, so i hope this problem is fixed in the later boards... i guess since i havent heard of dead a64s with a high 3.3v rail for months... ask other dfi 754 users, pretty much all of them run a bumped 3.3v rail i think :lol: i just dont know how high...

I've heard that the mosfets can get very hot... Is it neccesary to cool them? :confused: I can chop up some heatsinks and stick them on with thermal adhesive
Always cool mosfets. Some air on them would do them good too.

3.6v 24/7 would be safe...
what you can do is lift up the mem mosfets and solder a 5v line to them so that they draw their power from the 5v line instead. i did this to my IC7-g it works great!

Hey, wait. I just orderd a dfi, well it came yesterday. My 3.3v rail is at 3.7 right now on my antec 480trueblue, does that mean I can have my vdimm up to 3.6 or is that only with the ozc psu?
edit: n/m, found out. Thats great, I thought I'd have to mod it, or get a ddr booster. Thats really good news :banana: I don't gotta do anything :)

I don't know, I've had it up to 240 2-2-2-5 on my nf7-s at... hmm.. I think it was 3.4 maybe, and it wasn't stable, but that was because the proc. couldn't take it (11x240 locked barton). But I'm sure I can get it to 240 at least, havn't beenable to try any higher with it.
