I have a new POV GTX 480. Installed in an asus X38 board it was a pig to get going but after many bios resets and driver cleanouts it was installed with latest drivers for visita 64 bit.
card worked random lockups at first that improved quickly (themal compound setting?)
BUT benchmarks installed to test the card are very variable and usually pretty low for a e8400 and a quad 9550
2dmark06 is down at 11000 ish or max of 15000 with a quad 9550 at stock
heaven 2.1 benchmark runs at 25 frames per second or sometime 50 frames without me changing anything
GPU-z says the pci-e bandwidth is pci-e v1 not v2 and occaisonally the card reports its running at x16 or x8 or as low as x4 speed
Installed on a different P45 board much the same results though the card is more stable its performance is similarly lowish, goes up and down a lot and its still reporting anyhing from pci-e 2 x16 to pci-e 1.1 at x8.
It seems the pci-e connection speed may be a x38 chipset issue with nvidia drivers forcing pci-e v1 mode AND the speed of the pcie slot in the p45 board is propbaly not enought to half or double the benchmark performance but somethings odd, either the card is throttling itself or it does not have all the shaders working
Any similar expereinces or resolutions?
Is it possible to confirm all the shaders groups are enabled and working on these cards.
Attempts to check the 480 bios with nihibitor fail so i cant check the thermal or other details beyond its the current bios 21...2
