I'm looking for a cheap s939 opty here: http://www.overclock.net/wanted/5096...e-opteron.html

can anyone help me out w/ that here?

That's pretty weird isn't it. It didn't do this before when I had it setup for folding..
According to this PSU calculator, even with my rig overclocked to 3003mhz @ 1.55vcore @ 100% peak load it should only use 578w. If I add in 20% capacitor aging then it needs 631w. But this PCP&C PSU is brand new. So there shouldn't be any capacitor aging yet.
Have you tried a different PSU? I'll probably try mine sometime on Friday or this weekend. It's such a pain to get everything out of the case with this one.

BlackOmega, it's probably way less then that. You're probably doing like 170-240watts idle. Load (depending on if it's video or cpu) may be around 350watts. When I had my 4850 and opteron 170 I was barely doing 220 watts at load (Orthos and ATITool 3D View).

You're mainly just testing the parts so if you're limited due to working space just connect the other power supply and leave the existing one installed. The 24-pin ect should be long enough, I usually just sit the psu on the case and test things that way. Lay the case on it's side and try it that way. I know what you mean though man, I had all the power cables in my CM690 going behind the motherboard tray and in all kinds of other places

I'm sorry but was this the power supply that you tested with the multimeter and then did comparisons in the OS with SmartGuardian?

Good luck

The wierdest part is that there is no problem once it is running. In fact, booting up shouldn't even load the hardware (and therefore the PSU), right?
I can try with my 600w Ultra that I was going to use in my P:RiaGH case. My TT PSU may be the problem.

Yeah I just ran the calculator at 100% load on everything just to see how much power it could potentially draw if all the planets aligned and for some reason it used 100% of everything. It also gives me an idea of how big of a buffer to give myself. I'd rather have it use only 75-80% of the PSU rated power.
According to that PSU calculator, the cpu at stock, 2400 Mhz 1.35vcore, draws 121w @ 100% load. And a whopping 175w @ 3003 1.55vcore.



That's exactly how my CM590 is. I have everything run behind the mobo tray, even to pull the cabling through I actually need to unscrew the PSU from the case. I really need to make that hole just a wee bit larger.
Yeah the PCP&C 610w was the one I was testing.


Nate and th|nk3r, do you guys have the molex connector plugged in on your boards? I can't remember if it's a necessity or optional like on my old Asus board.

Nate, I'm wondering how much power is actually drawn when powering up. I know that by the time I get in to windows and coretemp boots up the temps are relatively high, so Im assuming that there is a considerable load upon startup.

I have the molex and the floppy connector plugged in, but only because I was told it's a good idea to use the ports (they're there for a reason). I forget what blitz told me exactly.

Theres a floppy connector on the board too?

Hi guys, I just wanted to drop by and say thank you to blitz & thlnk3r. They helped me out w/my dead Seagate drive. I just got my seagate HDD back from firmware and data recovery repair and I did not loose a single file FTW. Now I can play all my games again including NFSHS.

For the DFI LANParty boards, it is strongly recommended to have all power connectors (including the molex and the floppy power connector) plugged into the board.

Hmm... well it seems that the FDD connector is only supposed to be plugged in if you're running 2 GPUs'. I have never had it plugged in on any of my DFI boards (I dont know if the CFX even has one).

Have you guys noticed increased stability having it plugged in?

Now this is a total assumption but, when these boards were made a majority of the GPUs' didn't have a power connector on them. I'm assuming that since they didn't have these is why a lot of the 939 have a supplemental power point for them. Like the Molex on the A8N32.

But hey what could it hurt, I'll plug that little bugger in too. I'll do it later as I am studying for Anatomy & physiology.
