Hello, I have a dual core AMD 3800 cpu, and in games like Counterstrike/Half Life, and UT2K4, the games crash. At first I thought it was the RAM but the RAM is fine. I noticed in the UT2K4 Error logs it reads things like "unknown CPU 6453 ghz" or "unknown cpu -1830ghz" it is not reading the dual core cpu correctly. My question is, would getting a single core like an AMD 64 4000 solve this problem?

Oh yeah, also can this problem be corrected with drivers, a new OS like Vista whenever it comes out, or is the only way to get this to work is by having the game developer release a patch? Thanks

You might get a better answer in you post in the gaming forum...see what heropsycho has to say. If you go single core, the 3700+ San Diego is the CPU to get, or an Opteron. This was just touched upon recently http://www.computing.net/gaming/wwwboard/forum/6596.html

Ok Thanks. BTW just so everyone knows since I see noone mention this, but Quake 4 for the PC is optimized for dual cores with a 70% increase in performance. In fact that game loads faster then games that are 4 years old now, which is ironic since my last PC couldnt even handle the game at 640 X 480

I wouldn't see why it's the processor, but the games fault instead. Is there a patch fix for Counterstrike/Half life and UT2004 for dual cores? If not have you tried AMD's site to see if there is any patches for the processor running certain programs? I have seen dual cores play on these cores whicn included the X2 3800+ from benchmark sites like xbitlabs.com etc.. and I haven't heard of problems using dual cores with these games.

Counterstrike works fine with my dual core. AMD Athlon 64 X2 4200+ 2GB Dual Channel DDR 3200 Nvidia 6800GT SATA II 250gig 7200rpm 8mb cache Gigabyte Nforce 4 SLI

"BTW just so everyone knows since I see noone mention this, but Quake 4 for the PC is optimized for dual cores with a 70% increase in performance." It would be helpful if you post links to references/benchmarks when making such claims. The quake website (www.quake.com) states that the "performance gains in QUAKE 4 of anywhere from 25% - 87%". And, knowing how marketing people are, I would tend to believe the vast majority of users will be att he low end of that scale. Michael J
