Hi I am a recent convert to folding on a 9800gx2. I wonder if any one here can help?
Mr postman deliverd a 9800gx2 I bought over the internet yesterday I plugged it in to a old amd semprom mother board that had been folding nicely with a 8800gtx. Plugged it it and nothing tried other output nothing. reboot nothing.
OK I thought try in other computer, problem no 8pin pcie socket on psu. Answer swap psu. swapped psu removed two gts 250 and 9800gx2 works,. Put GTS 250 into old sempron got a warning insuficent power will reduce performance. so are 9800gx2 s not compatable with older motherboards?
thanks Mike

what psu's are you using? the gpu should pull 75w of the mb and 75w off the 6 pin and 150 off the 8 pin. if one of those is not adding up that may be your problem

PCIe standard might be an issue. The earliest revision boards may not support the wattage of the newer cards. The oldest board I ran one on was a P35 chipsetted Asus board. I assume you had the actual GFX card powered up with the correct plugs on the back?

You may want to look at any board that is compatible with your CPU with a more modern chipset. I can't imagine a new board would set you back much especially if you look at the open box deals on NewEgg.

The psu is 750 watts and it is ok on my other computer.

Yes all plugged in and lit up. It seems strange that I ran a ati 4850 with no issues. Thanks Mike

I found the 9800GX2 would not run on some of my mATX boards (despite having PCIe 2.0 cert) and would not run on an older P4 board. I really don't know why.

Found this...a bit late...count me in for 1...I love it!

just wondering, how hot does the gx2 get when folding, and how high you have to turn its fan up, last how loud does it get?

Mine runs pretty hot, even with the fan at 100%. Fortunately the cooler is on the quieter side, although still kind of noisy at 100. Over the summer with nice cool AC and 68F air mine was at 80C load. Now with no AC and two rigs folding and an ambient temp of ~78F in my room my GX2 can hit 100C.
