SiS or Intel for Celeron PPGA

[CMonster]

Has anyone tried the SiS chipset for overclocking the PPGA Celeron? Is it as good as the Intel BX chipset?

~~*reason I'm asking is that I have the chance to pick up a cheap board with this chipset and it does feature the 100mhz bus in a BIOS softmenu but there is no documentation in the manual included with the board about bus speeds or CPU voltage

You mean SIS is making PPGA motherboard chipsets? New to me, but I never have good luck with SIS.

Hi!

The P6 bus is the P6 bus is the P6 bus.

Regardless of whether it incarnates as socket-8 for Pentium Pro, slot-1, or socket-370 "PPGA", it's the same old P6 bus.
Any chipset suitable for one of those form factors is also suitable for the others.

SiS has been making P6 bus chipsets for quite a while - the 5600 and 600 non-integrated 66/100 MHz chipsets, and the 620 and forthcoming 630 with integrated AGP 3D VGA.

They aren't the performance leaders, but the integration pushers. The 620 combined with their 960 super south has VGA, sound, modem, 4 USB ports and 10/100 LAN in the chipset.

Bottom line - if you look for a cheap system for non-games use, SiS has what you are looking for.

Great, now if someone could tell me whether or not the CPU voltage is adjustable, how many bus speeds it might have, or if they have had any experience overclocing the socket 370 Celeron on a SiS based board that would be helpful.

I guess I'll Intel instead.

Hi again,

voltage regulator adjustment and clock generation options are not features of the various chipset - they are mainboard design decisions.

Thus it makes no sense to look for a certain chipset when you are actually looking for flexible clocking options or tweakable CPU voltage feeds. You must look at the mainboard designs themselves to find out about this.

Of course, most low-cost boards are designed to include just the features required for running processors within their normal parameters. Fancy stuff costs money.

Thanks for the info but it wasn't really what I was looking for.

Since it appeared to me that the voltage adjustments are done in the BIOS on this genaric-no-name-bare-bones board (if not entirely automatic): I guess to clarify what I am asking, it would be better to say, "Does anyone (user) have experience with a motherboard using a SIS chipset, and does your board have tweakable CPU voltage settings. Since I cannot test the board before laying out my $40 this information would be helpful in indicating that since there is a 100mhz bus there ought to be adjustable voltage.

I also wonder, is the performance noticably different between the SIS chipset and the Intel BX chipset; like the performance difference there has been between other Intel and VIA chipsets.

Yeah, I guess it is not likely to expect that the board mfgrs want to spend extra money on a cheap board - giving it all kinds of options...anyway...guess I'll never know now - the board was sold to someone else (oh, and it did have integrated video and sound).

I like to experiment (torture) on cheap things... - but I usually do wind up paying money for things - last time I tried to buy a motherboard with oranges they wouldn't allow my cart into the store
