Its a topic going back a couple years. I bought an MSI FX5900XT-VTD128. I am running Farcry at 1024x768-32, at HIGH texture and HIGH environment, no AA, no AF, MEDIUM else. It takes a fraction of a minute to work-harden but it keeps frame rates up where it is playable, maybe in twenties, thirty. I have a P4 2.6C oc'd by 20% to DDR480@2.5- 4-3-6-8 (or 2.5-3-4-6) w/ DCK EL OCZ 512MB RAM. There is no problem w/ the system as a whole until: I want to up res to 1280x1024. When I do the frame rate makes it lag to much to be enjoyable. I have 91.47 Foreceware and NVTweak, and it adds coolbits as I have it set as a "poweruser". Or maybe I already had OC clock bars? I can OC to 440/763 from 390/700. I do this and play still at 1024x768. But I get stuttering and even a stoppage. So I backed it off to 433/757 last night and played fine for 45mins. I assume its ok, I'll try again soon. Its fine.
I have read through here about trying RivaTuner, or flashing BIOS to the 5950Ultra. People are getting 500/800 and even >500 /950. I have the MSI, which is good(best) according to a review or two, FX5900XT Oc'er & in cooling, and I have lots of fans right at/by the already well cooled vid card. Going by these posts I can only assume I could expect to make a jump in overclocking if I knew how. So for starters: If I am getting stuttering at this low level of OC, could I expect to get rid of stuttering, and better yet, get 1280x1024 playable if I were to attempt other ways to OC?
Actually is it better to go to RivaTuner anyways, or is it req'd after a BIOS change. If there is a problem up'ing OC now, or stuttering, will it always be there w/ or w/o coolbits, or whatever "method" I have been using already? There is NVTune at nvidia.com; does that do anything to help, or is the sw BIOS adj. they talk about just for the mobo? Is RivaTuner old technology?
How do I determine if my RAM is 2.8, 2.5 or 2.2. That factor may be why some specs are /800, and some/950. I need to get to the bottom of that to get into the right ballpark I guess. I'm not at either now. [A] MSI FX5900XT-VTD18 review say Samsung 2.8. Took it out. Its Hynix marked F-28 (may be 2.2, or 2.5, checking numbers) The RAM starts at 700 and AutoDetect is 411/740, highest allowable yet 440/763. Can I flash to 5950U? Anybody know what Hynix HY5DU283222A batch 435U is? probly 2.5?
There are 2 things in the P4C800E-D mobo BIOS, AGP fre. (now locked at 66:33), and AGP (now 1.5V; & 1.6, 1.7, 1.8 options). Though not specifically a GPU Voltage, is it safe to go to 1.6V AGP to try a higher OC?
Thanks to the poster of "OC your 59XX...", and links I am better off at this moment....and I need to avoid what I'm doing and get RivaTuner, then maybe Powerstrip. The numbers may proove it.
