Sis655 owners!!! Need your results...

Asus P4SDX, 512mb PC3200 DDR (2x256) by OCZ, and a P4 2.4B processor at 2.6ghz. FSB at 145, according to the BIOS the DDR is at 434 and the system is rock solid under memtest, Prime95, and 3DMark. I'd go higher, but I'm using the Intel stock heatsink and I'm not comfortable with temps in the 60's at full load. I'm at around 53-55 under load now.

This setup was used on a non dual channel SiS648 mobo, where I couldn't bump up the FSB by more than 2mhz before Windows would crash when I booted. It was a flaky ECS L4S8A2.

I'm very pleased.. the Asus board is nice for a not very hardcore overclocker (the Asus board lacks a PCI/AGP lock and maxes out at 166mhz FSB) like me but it's fast enough and rock solid...good stuff Sandra is telling me I'm scoring in the range of 850E and a bit higher, 3DMark is at 12200 or so. Using a GF4 Ti4400 not overclocked.

Somebody out there must have a SiS 655 based mainboard running a Northwood Stable @ 180 + ???

If they did, why would they want to participate in this thread ?

i think its pretty obvious by now~

this thread has been up for 1 week and not a single person replied with the answer Duvie was looking for.

 

[First]

For an example of 180MHz FSB + on an SiS 655 board with a non-P4M CPU, see this thread.

Got the 8SQ800 board in fine, no problems. Had factory F5 BIOS
DID NOT FORMAT... figured I would try it and see what happens.
Installed BIGTOE's modded F5 BIOS

Started cranking it up, current settings:
BIOS Post says DDR 420
Set memory to 2.5-7-3-3, +.2v
Set CPU to 167mhz@1.575v
Locked AGP/PCI to 66/33
Top Performance OFF
Installed Gigabyte AGP driver
WCPUid says: 3522@167.73
Sandra Memeory bench: 4132/4123
2X40gb WD JBs on HighPoint SATA RocketRaid in RAID0

Bluescreened at 170mhz FSB Been at 167 for a couple weeks now.

This board is the AO stepping. Would like to have tried a BO if I could find one.

OK...That is the first legit one I saw, though since I don't regularly hang out there I can't tell what some of these ppl view as stable...Since if I got a board like that I would not need to run 2.7v memory and 450ddr I could and should run at my 3.33ghz level so I need 185fsb...His 181fsb level is a little too close to home.....


I have recently been hanging at the asusboards.com and to say the least Evan...I am not that impressed!!!! I would have hoped some good ATers I have seen here for the last year or so would have had success with this board...Thugs prety much stated it...
