Sis655 owners!!! Need your results...

[Duvie]

I want to know your fastest stable fsb you have been able to obtain with the chipset...No p4m's please as there appears to be some anamoly related to them...I want confirmed stable fsb with good ol p4 northwood desktop chips. Let me know if the chip had also ran on another non DCDDR mobo and done better or less. Make sure this is prime95 and memtest stable and not sissfot benchmark stable, please!!!


List:

CPU:
MOBO:
FSB:
Ram and settings:


I would like to possibly get one but only if I know it will run my chip at the same 180+fsb level I run now....

 

[ErikaeanLogic]

<bump> for a darn good question!

 

[Duvie]

c'mon ppl....I heard from a big mouth that quite a few ATers had these boards over 169fsb...I want to see it...

 

[caboob]

you're not gonna see big OCs from the Asus boards for sure unless they have pulled off some BIOS magic recently.

 

[Duvie]

Why is that??? Limited on the available fsb that can be adjusted??? More details...This is on the p4Sdx right???

 

[Booter]

Hang on Duvie i will post my oc results with a p4 2.26 soon

 

[cobrasvt]

Head on over to here. You will find great information on these boards.

 

[Duvie]

Yep been there...problem is most ppl are either running them with high multiplier chips or have older chips that can't do 160 anyways....About worthless for the answers I need!!!

Yes, I meant the FSB that only goes up to 166MHz. I'm sure this is limited by the BIOS since their other boards have IC chips that can handle much higher bus speeds (if they are using them).

 

[caboob]

so far duvie ive seen one guy at the OCforums with an Gigabyte SINXP that he claims stable at 189. I've yet to get an answer from him on how he tested stability. Said he was able to POST out to 195.

My thoughts exactly. I've been searching for an answer to this same question for weeks now, but have found no solid answers.


It would be nice to see a Max Stable Overclock Shootout - 845PE vs SiS655 review with a decent overclocking 2.4GHz or 2.53GHz Multi VID CPU.

If the SiS 655 chipset based mainboards can't do well over 170 Stable, it would be a Downgrade for many 845PE owners.

 

[nwfsnake]

I'm not really an overclocker, but my MSI 655 Max board is pretty weak in the overclocking department. I tried the MSI overclocking tool, and it would just lock up. I then tried to manually (via the bios) increase the FSB to 134, and it would reboot! It is very stable at defaults running dual-ddr corsairs at 200 mhz and 2t, though. Great factory default board, bad overclocker.... Using a p4 2.4B.

 

[THUGSROOK]

Face it Duvie ~ SiS boards are still budget boards.

 

[Duvie]

Where is ToBeMe???? I knew he was blowing smokle up my arse saying that many ppl have hah these things well above the 160's in fsb.....I call BS unless you can give me proof!!!

 

[caboob]

While I would be inclined to wait for people in the forums to speak up with their success with this chipset. Evans sneak peek at 800MHz performance is a good indicator that the SINXP is the board to get that can handle high FSB.

 

[Budman]

Duvie,just be patient for now & wait for Canterwood.

The review was with a P4M CPU.

 

[caboob]

Whoops! missed that detail, my bad...

however, use of the mobile processor has been a good predictor of mobo limitations like the FSB limitations of the 8INXP. Whether it gets solved by a BIOS flash remains to be seen but I dont hold out much hope with Springdale/Canterwood being so close. With that said, it is sensible to wait for a real processor to be succesful on this chipset.

I have been running my Gigabyte 8SQ800 @ 148 MHz 24-7 for 3 weeks running my P4 2.8 @ 3.1 (21x148). I would have liked to get a bigger OC but, I do a lot of DV editing and need 100% stability so 148 was about as far as I was willing to go. This is at stock voltage w/ the retail HSF.

I´ve been running my Gigabyte GA8SINXP1394 with a 2.4B at 2.91 stable for about 3 weeks now just with air cooling (boxed cooler) and default voltage. I´m using 2x256MB Corsair PC3500.

Awesome whats your FSB?

 

[caboob]

that would be 2910 / 18 = 162 MHz rounded up. what is the stepping/FPO batch number on that CPU?

I know as we pm'd about this...Same board could not get a p4 non mobile chip any higher then reports of the 160's...

The guys at asusboards.com a few of them have been using the windows based fsb tuners and say that helps them get about another 7fsb...makes me think bios issues with a restart issues related to vcore as we saw in the early days of i845d boards.

 

[THUGSROOK]

are these b0 chips or c1 chips?

as we all know already the b0 chips have a prefetch bug and can overclock easier with less vcore and less vcore flux. (that does not mean b0 can OC farther, just easier)
prefetch makes for harder overclocking. (cache crashes easier under full load)

perhaps they used a b0 P4m but the P4 was a c1?

 

[mrshadow]

I´m sorry, Caboob, i don´t know the batch number of that cpu. All i can tell you that it was bought in November last year.
Right now i´m looking for an affordable watercooling solution because i feel i can take that cpu even higher with better cooling.

All in all i´m pretty content with this board. It is fast, stable and has lot of features. But i´m sure you knew that
