The first two mobo's use the new i845E and i845G chipsets from Intel but only support PC2100 DDR SDRAM.
The P4S533 uses the SIS645DX chipset and supports PC2700 DDR SDRAM but not USB 2.0..


Which motherboard would you pick in terms of performance??

i would get the 645DX

if your worried about USB2.0 u can allways pick up a usb2 PCI card for a few bucks.

i second the P4S533...
the P4S533 also has "unofficial" support for pc3200 too.

alright thx.

but I heard there were problems with the SIS 645?.. Not quite sure if it's true or just a rumor..
but was it true people had problems with the SIS 645 and compatability with certain video cards? I heard it killed people's CPU or had a whole lot of problems before?..
I'm not sure with the new P4S533 as it's using the SIS645 DX chipset..

That's a problem with Intel chipsets not SIS. If you plug in a card that doesn't support 1.5V, you'll fry your motherboard.

Alright thanks.

So there should be NO problems what so ever with SIS then?

what is "unoffical" support?
As it will support PC3200 just with a bios update??
Sorry don't quite understand how it works..

to succinctly answer your questions.

1. 645 rumor: no idea.
2. vid compatibility: also no idea.
3. killing cpu's: still no idea.

while i know a bit about them generally, P4 motherboards arnt quite my Forte'.

No, it's just that Asus doesn't have DDR400 support written down in the manual but you can run your RAM at 400MHz without overclocking (if you have DDR400).

The 645 rumour doesn't exist as far as I know.

The video card compatiblity is an issue with Intel-based motherboards because they only support 1.5V AGP cards.

The killing CPU rumour is a possibility. The extra voltage might fry the CPU along with the motherboard.

haha alright then.
Why are the new i845G and i845E more expensive when they don't offer anything more than the SIS645DX chipset?

i845G has the built in AGP controller.. understandable..
but i845E?.. that I quite don't understand..
I mean do you get better performance since the chipset is built by Intel?

Okay then.
Well I haven't seen any CL2 PC3200 DDR SDRAM yet
so would I be better off with PC2700 CL2 or PC3200 CL2.5?
June 14, 2002 11:20:23 AM

That depends, which PC3200 CL2.5 are you looking at? Most PC3200 can easily handle the CL2 at 400MHz without any problems.

Alright..
well what company would you suggest for PC3200?
I heard that some can't handle PC3200 at CL2 and the performance would just turn out even worse..
June 15, 2002 9:19:48 PM

Nah, the only place I heard something like that was in Tom's Hardware's RDRAM vs. DDR RAM. Tom's Hardware is very conservative most of the time, when it comes to overclocking. Any PC3200 should handle maximum settings but you might have to raise the voltage 0.1 or 0.2V.

Okay thx.
Well I'm most likely getting a 1.6A GHz Northwood so by having PC3200 will I get that much more performance?
and is it going to be noticeable?
I just can't exactly figure out if I'm better off paying the extra cash for PC3200 DDR400 or sticking to PC2700 and get similar results..
June 16, 2002 12:30:56 AM

You're best bet is to stick to Samsung PC2700 and overclock it to 400MHz.

:wink: <b><i>"A penny saved is a penny earned!"</i></b> :wink:

Just a simple question.

If I overclock the 1.6a or 1.8a just by setting the fsb to 133, then every component should be at stock speed and just the cpu is overclocked?

Yup!

Alright thanks!
It wouldn't make any difference if I bought either Corsair, Mushkin, or Samsung DDR-SDRAM would it?
As they are all using Samsung's chip...

id like to see some proof of that...
anyways....as for the AGP thing...a 3.3v card will not fit into a mobo that supports only 1.5v...just FYI...so you wont have to worry about that....and besides...the sis645DX chip supports pretty much all agp video cards.
as for the ram...your best bet is to stick with samsung ram on samsung pcb...its just safer that way.

I said PC3200, not PC2700. If the RAM is rated at PC3200 CL2.5, pushing it to CL2 shouldn't be hard although you might need to raise the voltage a bit.
