nloding Posted December 18, 2005 Posted December 18, 2005 So I've overclocked my Opteron 170 with the specs below (11/25 bios on eXpert board). Dual SuperPI32M stable, dual Prime95 stable for 20+ hours, Memtest 1.65 ran for 18 hours with no memory errors. I get 26k in 3dMark03, 12k in 3dMark05. I have two 7800GT's in SLI with multi-GPU rendering enabled. I have tried 7 different driver versions, with OCing and without on the video cards. I have installed the dual-core XP fixes and ran the reg patches. I've tried launching games with only one core set for that process ... FarCry, Half-Life 2, UT2004 ... I can max out all the settings on these games and they run beautifully. Quake IV, F.E.A.R., Doom 3 ... I max out the settings and get less than 7fps. I've tried the BETA dual-core 1.0.5 patch for Q4 and it still happens. These games are supposed multi-threaded ... I wonder if that's the issue. So I started trying settings on Quake 4. The game only lags when I run it on Ultra Quality. If I keep everything else the same, except drop it to High Quality, the thing works beautifully. I can live with this if need be. But I would prefer to have it on Ultra Quality. Anyone know what is up? Any advice at all? ANYTHING?? Oh, I also removed the OC on the proc and did a fresh load of Windows -- same thing. I'm so lost ... Quote Share this post Link to post Share on other sites More sharing options...
nloding Posted December 19, 2005 Posted December 19, 2005 In further testing, I ran End-It-All and killed all non-critical processes. I also disconnected all but my main hard drive and one DVD-RW drive and tried everything out. It made no difference. I've been searching the web and can't find anyone with an issue like this -- for them, if they use WinLauncher or something and force the program to use only Core 0 or Core 1, it fixes the issue ... but not with me. On my A8N-SLI Deluxe with a 3500+ and 2GB of Ballistix Tracer I was able to max out Quake IV and FEAR and they ran great. What's up?

Zard0z Posted December 19, 2005 Posted December 19, 2005 On quake 4 ulta mode needs 2gb of system RAM to get the results you want. Even with 2 GTX cards at 512 wont do it. Read this on a Quake site somewhere. I have only one gtx card but 2gb ram so I could not test it myself. Z Quote Share this post Link to post Share on other sites More sharing options...
325cic Posted December 19, 2005 Posted December 19, 2005 I agree, most game today require 2g rams to run smoothly: doom 3 and FEAR .special u run dual core.I heard someone said b4"dual core and 1g ram will be bottleneck" but what the hell, I ran dual core with 1g rams myself. work fine with me even u have 2 7800GT 256M in SLI. it won't make any different because in SLI mode 256 + 256 = 256m would u want to spend extra $250+ for 2g rams to get your 7fps different :nod: Quote Share this post Link to post Share on other sites More sharing options...
0V3RC10CK3D Posted December 20, 2005 Posted December 20, 2005 yeah 512mb of VRAM is stated to be required to even run Ultra settings Quote Share this post Link to post Share on other sites More sharing options...
nloding Posted December 20, 2005 Posted December 20, 2005 The RAM could be the issue, but for some reason I doubt it. When I check my memory usage during gameplay, less than 1GB is taken up when attempting Ultra Quality. Maybe I'll give it a shot though, as I have 4 512MB sticks of Ballistix Tracer sitting here ... hopefully they'll clock to DDR480 ... I have yet to fully test FEAR, but I think that it will yield similar results: Maximum quality lags, but one step below while maxing out everything else will run like a charm. I'll try the 2GB RAM idea later this week and see. Quote Share this post Link to post Share on other sites More sharing options...
nloding Posted December 21, 2005 Posted December 21, 2005 Quake IV worked on Ultra Quality with 2GB Ballistix Tracer, but I had to drop it on the 5/6 divider so it's at DDR400. Unsure if I can stably clock it higher. So which is better, 2GB of DDR400 (4 512's -- 10,138 3DMarks, Ultra Quality) or 1GB DDR480 (2 512 -- same latency's -- 12,208 3DMarks, no Ultra Quality)? That's purely an opinion question ........ I think I"m gonna switch back to my GEiL 1GB kit, but what does someone else think?

finagle69 Posted December 21, 2005 Posted December 21, 2005 those games run fine on my sys. Need For Speed: Most Wanted jitters like a bastard though, haven't figured this one out. to your topic.. have you tried messing with the two "errata" options in the BIOS? i disabled errata 123 and performance increased. not sure if it would help you or not, but worth a try.

nloding Posted December 21, 2005 Posted December 21, 2005 to your topic.. have you tried messing with the two "errata" options in the BIOS? i disabled errata 123 and performance increased. not sure if it would help you or not, but worth a try. I have not because I had no idea what they were. I'll play with that tonight. I think I'm going to stick with my Geil RAM at 480 for now. High Quality vs Ultra Quality is not that different, and I still had some lag in Ultra ... Next year I may upgrade to 2x 1GB sticks of something awesome, but for now I'm happy. I gotta upgrade other things now, like my camera ... mmmmm lenses.... Quote Share this post Link to post Share on other sites More sharing options...
