P4 prescott C 2.4 @ 3ghz abit vt7 agp/pci locked to 66/33

[SOcRatEs]

I succefully locked apg/pci to 66/33
using the ratio's in the bios.
ddr400 @ 402
GPU OC'd @ 425/1.10
Seems very stable so far, no bench test yet.

Good thread!

If your ram is rated to do 3-4-8-8, setting anything more agressive in the Bios (e.g. 2-2-2-5) will cause your system to hang, have Bios error beeps, or have a bunch of memory errors in a memory testing program like MemTest86. Having memory errors will probably trash your OS and the data on your hard drive.

Not a bottle neck I'd want to mess with.
It's still running stable.
Runs Unreal II awakenings very well @
1280x1024 32 all settings high.
I will try a bench mark in the morn...
Thankz for the lead on the thread! Blakhart

Hi
Well, I think one should reduce mem timings if they can do so with stability. Just because mem is rated by the factory at 8/3/3/3 does not mean that it can't do better, and I always shoot for 6/2/2/2 no matter what the fsb is, if that set is unstable, I do the next; 7/2/2/2 and test again, ad infinitum. Upping the voltage to memory can help. I use memtest exclusively, and with it find the mem timings that reduce latency to the bare minimum, while resulting in best bandwidth for that specific system's mem and fsb.
I feel that reducing mem timings/latency is needed for any online activity that demands absolute responsiveness. This includes fps games and flight sims.

As minimal an OC (26%+ 600mhz increase), it's amazing how stable and cool
my system is running! Not alot of noticable system speed increase.
The zalman vga cooler dropped the 6800 temps (under load) to no higher than
117f, it used to be 146f. unreal II, UT2004

I messed around in the bios, and could not find a higher ratio that locked
the agp/pci @ 66/33.
What can I expect from value MoBo?

VIA never came out with a working lock for the
North Bridge VIA Apollo PT880 chipset. Abit vt7
I now this cpu can go to 3.6/7 with good cooling but I'm looking around for
intel chipset to do it.
