Hi guys. My XP rig has been underperforming in benchmarks and some games - so I decided to take a look and see what was wrong - I noticed the video card was running at PCI-E 1.1 4x... I did the usual (update drivers, update BIOS, check BIOS settings, re-seat the video card) to no avail - I even tried other PCI-E slots - still runs at 4x. I swapped it for a 8800GTX and guess what - it runs at PCI-E 1.0 16x - so there's theoretically nothing wrong with the motherboard... then I put the GTX 280 in my guest gaming machine (Asrock 970 gen 3) and it ran at PCI-E 2.0 16x... what gives? Any ideas? Here's the machine in question:
Intel Q6600 B0 @ 3GHz (9x333Mhz)
Asus P5K64 WS (Intel P35 DDR3)
2x2GB Corsair XMS3 1333Mhz CL9
EVGA GTX 280 + Arctic Cooling Accelero Extreme
Corsair VS650
2x250GB SATA HDD (1xWD 1xSeagate)
Xfi Xtreme Audio PCI
Huge Chieftec server case (made out of recycled WW2 KV-1 heavy tanks)
In 3dmark06 the 280 + stock cooler got about 15k points with the same parts but using a Zotac nforce 780i mainboard and 2GB of 1066MHz DDR2 ram - the card ran at 16x. With the P35 and the card running at 4x it gets a sad 12500 pts, witch is about on par with a 2900XT, and less then the 13400 points my 8800GTX gets...
So what do you think is going on? Any input is good input...
