hi there I bought an inno3d geforce 6600 128 mb agp card but having a strange problem i installed the card into my system ..and the system hangs during POST ( where it is supposed to display the list of IDEs ) nothing seemed to work ... however the system wasnt totally stuck, I mean presing the TAB key displayed my mobo's logo .. and delete key wud say go -> setup .. but it never did anything .. not even went in to bios setup I reset the CMOS and the system ran fine until I set the bios settings to high performance default values .. similar problem arrived again .. i eventually figured out that only when i turn the DRAM timings settings from ultra to fast .. the card runs fine .. no other settings seem to affect it though wierdest problem I've ever had with a gfx card ,, I also tried a 350w generic PSU ... and also tried removing all the peripherals .. but no luck the card wont run at DRAM timings set to ultra ... My friends 6600gt runs just fine on his 300w generic psu whilst his system is far more power hungry than mine . ( p4 2.8 prescott ) .. I even tried putting in his 6600gt .. same problem .. looks like its something to do with my setup.. by the way .. wud i get a lot of performance difference if i manage to run my system at ultra DRAM settings ? ( i benched the card .. and got 4550 3dmark2k3 .. do u think its a fair enuf score on my setup ? ) I wonder it wud be even better if DRAM is set to ultra .. and has anyone else experieneced a similar kind of problem ?
