1000hx can't keep up? - Page 3

post #21 of 29
Thread Starter 
i forgot one other change i made... i went from using slots 1 and 3 to 1 and 2... so before it was 16x/8x and now it is 16x/16x...

for testing purposes, is there a way to force 8x on the pci-e lanes?

I have a similar system (dual loops\\pumps ect) so I was curious, I didn't think I was close to maxing the PSU. I have Everest as well (well Aida64) so I monitored the +12v.

Idle - 11.760v
Games - 11.704vv
Furmark - 11.648v

Seems your getting a larger voltage drop if Everest\\Aida is to be believed, I'm just not sure if it's an acceptable level or a possible indicator of a problem.

thanks for the info

i'm reinstalling windows 7 and only going to install the latest nvidia drivers and furmark. Figured why not... can't hurt to try

reinstall did not help

at this point, since each gpu can run successfully by itself, I'm going to go ahead and order a ax1200 just to rule that out as a problem.

i'll report back in a couple days after amazon get's me the new psu

That's still within ATX +/- 5% tolerances. (Not that software voltage readings are to be relied on, anyway.)

this isn't much of an update, still waiting on the AX1200 and

(I don't think this was necessary, but I had been meaning to do this since my GSKILL ram http://www.newegg.com/Product/Product.aspx?Item=N82E16820231306 couldn't ever run, since day 1, what it was spec'd for. So I'll RMA this and my HX1000).

But I did stress each GPU by itself for an 1hr 45min in FurMark, 2560x1600 resolution. I tested each one by changing what GPU the monitor was plugged into and disabling SLI. Whatever GPU the monitor was plugged into, was the GPU that was used. This simultaneously tested the PCI-e slots they are plugged into as well.

GPU 1


GPU 2


as you can see, they each work like a champ when run independently from each other. Heat is not an issue nor is anything else that I can see. I tried to get a log of them in SLI, but it crashes immediately and the logs capture nothing. Just as an aside, I tried 2 different SLI bridges as well.

popped the new psu in (didn't put new ram in yet)... prelim results good. Running for 4 minutes so far in FurMark (will let it go for 1hr 45min)

psu was the problem for sure. I ended up stopping the FurMark test after 30min and declared the system stable (for ****s and giggles I also did a few passes in LinX after I installed the new RAM... the system passed that test like a champ too).

thanks for everyone's help an suggestions
