Power Bios feature: "System Peformance"

[disco_bazoon]

Hello there, I'm new here! *oh wait, that rimes!* lol
Anyway, got my 8KDA3+ last week, and so far I love it. I'm running my NewCastle 3200+ at 250x10 with my gigabyte of OCZ PC3500 EB ram synced 1:1 3-3-2-8, so that's all good. The board and memory is certainly capable of more, but I need some better cooling for the cpu before I go further ahead.
Now on to the question, there's a feature in the power bios on this board called "system peformance", which can be set to "normal", or "fastest". I clocked everything down to 200fsb again, and tried with it at normal and fastest. At "fastest" i gained roughly 200 points in 3dmark 01 or so, still same mem/cpu scores in sandra though. But with this feature at "fastest", I cannot run 250x10 stable anymore, it crashes to desktop when I run benchmarks and similar. So basically I'm just wondering what this feature is, and what it exactly does? It kinda looks like the cpu interface feature, which is on abit nf7 boards, for example - though I'm sure that feature also increased memory bandwidth scores in sandra as well as 3dmark scores.
So.... what is it?

Hell if I know but Man I sure would like to, on my gigabyte K8npro it had something like that which would increase the clock speed aprox 10Mhz no clock change on this board though? What does it do, indeed the question ?

heh, enabling that feature caused lockups on my old computer when it was running at stock. I believe it tweaks memory timings and latency of some things, but im not sure, would be interested in what exactly it does

Hmm.. indeed. Some one here ought to know what it exactly is, and does.
ET, where are you? lol

I could never get my 8K3A's to run at anything other than "Normal", regardless of memory or CPU. I don't believe the 8RDA+ even has this setting, if so, then I haven't fiddled with it at all

To the best of my understanding it's more a compatibility setting. Normal put less demand upon parts performing dead on as they communicate with one another. In short it tweaks system timings.

The 8RDA+ has this timing and I've used both settings to good effect as I've run various CPU and RAM combos through it.
