CAS settings in BIOS?

[theYANK]

If I change it from 2.5 to 2 does that ACTUALLY set it at CAS 2 or is this just cosmetic? Yes, I read the PC2700 thread but I didn't get a direct answer to this.

Yes it changes it.

THX KJ, damn you're quick! :D

Of course I am, I'm the forum w[H]0r3 :p

well, when I'm not studying and doing assign-... err, gotta go... :eek:

OK, If thats the case, then why didn't my SiSoft Sandra Memory benches improve when I changed my XP333 Mobo CAS settings from 2.5 to 2?
This has me stumped, as I can't get my Memory benches to even beat a Ali chipset running PC2100 at CAS 2 :-(
(will post benches Monday)

Ahhhh - you're an XP333 user.... ahhh... that explains everything.

OK, ANY VIA, Intel, AMD, you name it, most motherboards will simply change their CAS timing and take the performance benifit.

BUT

The XP33 is basically just weird. It does strange things like run memory asyncronous, shuffle fsb's and memory timings all over the place without you telling it to.

Moral of the story? It's just your board, nothing much you can do. Nobody seems to know ( possibly ALi? ) what the hell those boards do when you tweak them. :rolleyes:

KJ is on the money here. My old XP333 was the same: no performance increase with CAS 2 enabled. There was also no performance benefit from the, SLOW, NORMAL, FAST, ULTRA, ULTRA2 setting either - actually the only difference was that with ULTRA2 enabled the comp would not POST.


So yes, as KJ said the XP333 is just a weird MOFOBO, and there's nothing much you can do.
