Very poor 3DMark06 SM2/SM3 performance with GTX 260 216 SP Tags: Graphics Cards Gtx Performance Graphics Last response: January 10, 2009 1:12 PM in Graphics & Displays Share Pride January 10, 2009 11:36:29 AM My problem is very lousy Shader 2.0 and Shader 3.0 performance in 3DMark06 (v1.1.0). Graphics card is Gainward 260 GTX 216 SP Limited Edition 894 MB. RIG E6750 @ 3.2GHz (also tried without OC, only real difference is CPU score, not Shader 2/3 score) 2x 1GB 4-4-4-12 800MHz DDR2 (800MHz without and with OC) Antec NeoHE 550W RESULTS ForceWare 180.84 SM2.0: 4449 (stock clocks) ForceWare 180.84 SM3.0: 4346 (stock clocks) Best results I have reached are these. I have also tried 181.20 drivers, which gave few hundred less points on both shader tests. I tried 185.20 as well, but with those I couldn't even get to Windows XP login screen, since after "XP loading screen" there weren't any signal coming to my display. ...thing is, I had 4850 1GB OC (factory OC) which performed better. What on earth is going on? I was expecting to see around 6000 points for shader tests. Is it possible that GPU isn't getting power through both PCI-E 6-pin connectors or something? What would happen if only one of those was attached (although I have two, but if there's an issue) Best result this far in overall 3DMark06 score is 10422 with E6750 @ 3.2GHz and GTX 260 (216 SP), which seems like approx 4k less than it should be.

My motherboard is Asus P5K. There aren't direct controls to PCI Express bus, only possibility is to lock it to 1x or then not. And it sure isn't locked to 1x. I tried upping PCI Express from 100MHz to 105MHz. No help. I also tried enabling PCI Express Spread Spectrum, no help. m 0 l LordPie January 10, 2009 12:31:08 PM After a quick search on the board it appears to be a crossfire one, and according to it's specs one of the PCI-E slots maxes out at 4x. "2 x PCIe x16 (blue @ x16 mode, black @ x4 or x1 mode) supports CrossFire Technology" try swapping it to the other slot and it should fix the issue m 0 l Can't find your answer ? Ask !
