Interesting Observation

[TKH]

Well I'm not a fan of overclocking but for the whole week I've been trying to oc my rig to see how well it can handle. I oc the 2600+ to 175*12.5, my system beats 2800+ in Sisoft Sandra 2003, and come very close to 3000+. But I found out that if I set my Kingston PC2700 at 3-4-4-8, my system won't POST, at 2.5-3-3-7 my memory benchmark is better than 2-3-3-6. So does this means that relax the memory timing is not a bad idea? Another note is that I use Hercules 3D Teaker 3 to oc my 3D Propphet 9700Pro, at stock 324/311 I got ~590FPS, then before I oc the CPU (so it's 166*12.5), I oc to 342/324, I got ~630FPS; after I oc the CPU I got a whoooopping 850FPS. I always thought that the change in FSB won't affect GPU... so can anyone tell me why is this? (I swear I didn't have alcohol that night... ok, I had one drink... all right, two ^_^')
Oh, and one last question: how do I enable Sideband Addressing?

about the RAM... I don't know why "relax" the ram is better
about the changing FSB.. it affects the CPU somehow, but as your CPU, 166 to 175Mhz, it's not a big overclocking, so it SHOULDN'T affect your cpu from my point of view
oh yeah, the sideband addressing..it's disabled for you? I guess that you have to install AGP driver, but I'm not sure, cuz it's always enabled on my system..

Well I don't really trust SANDRA benchmarks it is really strange that memory at faster timings runs slower then memory at slo timings IF they run at the same speed in MHz. Unless ofcourse the memory can't run stable at the faster timings and keeps missing cycles.

And which game did you use for benchmarking... seeing that insane high framerate I would guess something like Q3 or based on the Q3 engine. If so it makes a lot of sense that a higher CPU speed boosts the FPS a lot because the Q3 engine is very CPU dependent.

My CPU fan spins so fast that it creates a wormhole

Yeah, I know, 166 -> 175MHz is not a big deal, but I've said I'm not a fan of oc, I just try to see what will happen, and actually now I've switch back to 166MHz because, yeah, I don't see any differences beside Sisoft benchmark.
Do you mean the GART driver from ATI (R9700P) or the GART driver from nVidia (nForce2)?

I'm also pretty interesting in the memory timing, from nForcersHQ, many people also report that running higher memory timing at high FSB is better than low timing. I believe this has something to do with the stability.
I'm not using any game for benchmarking. I mean the FPS shown in the 3D Tweaker.

hm..I'm not sure what's that called with nForce2's driver, I'm using a KT333, so for me,it's the "VIA 4 in 1 drivers"
but i'm certainly NOT talking about the GART driver from ATI

Hey, I've got the SBA working. It happens that I have to disable Fast Write in order to enable SBA. So I can only have one of them (FW or SBA) working. Thnx for your input anyway.
