Here is a run from my Socket A build. System info not shown on the screen:
Motherboard: EpoX 8rga+ nForce2
CPU: 2500+ Barton
Memory: 2x512MB Corsair CMX3200C2 v5.4, timings 2, 3, 3, 6
Water blocks on CPU and GPU. GPU is stable with higher core clocks, but for some reason I get crashes with Freelancer anything above 450. Every other game and 3DMark benchmark works just fine, that is the only thing that so far seems to be unstable beyond 450. Also for the rest of the system, my Corsair memory or nForce2 memory controller doesn't want to go much higher than 200MHz as it is. I need to test other sticks further, but it may be that 512MB double sided ram and dual channel is just hitting the limits of the memory controller. Back in the day in 2003 when this system was released and relevant, the best performance was achieved usually with 2x256MB single sided sticks. I tested shortly memory in async mode and I could get higher FSB easily, so the limit is 100% on the memory side of things.
As I said, I have bunch of other memory modules available, so I may test other options, but I'll take 200MHz gladly with such timings and 1GB of RAM. I need to source XP-m Barton to get unlocked multiplier and potentially higher CPU clocks, though. I don't think this system can go to 6000 points mark, but I can probably squeeze a bit more with 100-200MHz higher CPU clocks.
