Celery 566 on a Soyo 7vca only oc to 638, wtf?

[wonder mike]

I'm i doing something wrong?? I slap and PIII 500 in there and it's overclocks to 800. With the celery it only goes to 638. Here are the system specs. Celery 566, 64 megs pc133 (7.5ns), voodoo3 pci, generic sound card, and acer cdr. I've got the latest bios revision, do I just have a bad chip?

Have you tried uping the volatge on your chip? I couldn't get my 566 to the 850 without pushing the volatge to 1.75.

 

[Citadel]

Wonder Mike, as thxturtle said you will most likely have to increase the core voltage to somewhere around 1.65 - 1.75. What kind of Heatsink/Fan are you using? Retail?

 

[Scaramouche]

Same situation here. 850 with an Abit BH6 at 1.65v, nothing higher than 566 with an Asus P3V4X at up to 1.80v!

 

[wonder mike]

Ok i'm not too big of a overclocking newbie, I got three other oc machines. I'm using a thermal take golden orb with a thin layer of paste. I'ved increased the voltage to +10% with no luck. Does anyone think 4-interleaving has anything to do with it?

 

[bonkers325]

maybe your chip wont go any higher

 

[Killrose]

you got a dud.

 

[wonder mike]

Bah, that's what I thought. I'm always so unlucky when it comes to buying dud cpus.

 

[MadRat]

I don't know... isn't that the Soyo integrated m/b and case based on the 810 chipset?

 

[Scaramouche]

Follow up to my Asus P3V4X not being able to overclock the C566. I pulled the battery to reset the CMOS, loaded the setup defaults and was able to hit 850 at 1.65v. You may want to try this with the Soyo.

 

[wonder mike]

Well I had the celery running my Soyo 7vca (via)and it would only go to 638. I put the celery into my Soyo 6ba+IV (bx) and bam 850 rock
solid. I wonder if other people are having this problem with the via chipset.

It seems the relationship of the SLOTKET to the MOBO is the key factor in alot of Celery II oclocking. I've seen so many people here say This slotket works with This MOBO. Generic slotkets work fine with some chips and some MOBO's , mostly they don't work well.
Some of the choices (ABIT,ASUS,IWILL,MSI) work better on some boards, but not so good on others..

I've yet to see a chip not run at like 81X8.5, but you may have gotten an UBER-DUD. Sell it on fleabay to recover your money, or fry it if its under warranty(!!) and return it for another try.

I'd strongly look at the slotket. Keep in mind Many MOBO's dont honor the voltage setting of the SLOTKET, rather, use the bios settings regardless of the SLOTKET's voltage setting. ABIT comes to mind in this case. However other boards, rely solely on the dip switch settings.

Flash your bios, with the clean option and the latest bios rev to ensure the MOBO has got the latest rev BIOS and a clean settings slate for the transition to the PIII world.

Maybe some others can comment on their SLOTKET <-> MOBO success and failure combinations.

For me:
MSI <-> Intel 810 , flawless, uses jumpers to set voltage.
ABIT <-> ABIT BH6 , 850 max at 1.75, bios QN, Voltage flash trick, does not honor SLOTKET voltage AT ALL.

 

[wonder mike]

Heh the 7vca is the a socketed board, no converter card needed. I can put my PIII 500e in and it rocks hard at 750

One of the peculiarities of the via chipset is the possibility of running the memory at plus or minus 33 mhz of the fsb. I'm not familiar with the soyo board, but you may have overlooked this setting in the bios. Set wrong, it will stop you dead, and this may be happening automatically when the celeron and 100mhz Ram are detected.

 

[wonder mike]

Nope checked that, i was running it at -33 at 100 fsb at one point and it still didn't work. i do have 7ns pc 133 mem i'm using so i doubt that's the case
