I just purchased a Soyo SY-6VBA 133 and a Celeron II 533. I cant seem to raise the boards FSB frequency to 100 mhz. Most adjustments are done in the bios with a few jumper exceptions. The problem is I think the board is auto-detecting and will not allow me to raise the FSB. I just read covering B21 may help, but I don't know where B21 is located on the convertor card. Also my convertor card auto-detects too. Would it help if I bought a card that had jumpers?
You would cover B21 on the slotket, not on the CPU.
Thank you Nixona, but how would I know which pin or contact on the sloket was pin B21? If I was looking at the convertor card, (cpu facing me) would I start counting from left to right, or right to left? Secondly how many contacts do I count off? 21? Sorry for sounding so dumb in this, but This really is my first experience with Celerons.
Probably needs a little more voltage to boot up at 100mhz. If you can change on Slocket, thats good, because when it first boots up it boots at 2.0 v, at 66, 100, or 133, I believe. Then changes once BIOS Takes control?
Yes, I think that's how they work - the CPU has to initially run at the base FSB frequency that you set, then the BIOS either ramps it up or down, depending what you set in SoftMenu.
There are four jumpers that you need to set - two sort out the FSB group and the other two sort the AGP divider. The PCI divider is taken care of automatically.
I've got the installation manual that came with mine here (BIOS rev. 2ba4) The jumpers are likely to be the same for yours.
To get 100MHz FSB, you need JP8 open and JP9 short.
To get the correct AGP divider for this FSB group, you need JP7 open and JP2 shorting between pins 1 and 2.
If you had not set the correct AGP divvy, (FSB/1.5), the AGP clock would have initialised at 100MHz when you changed JP 8 & 9. This could have been the problem..?
Also, check stuff like memory timings - is is at CAS2? If so, try dropping to CAS3, then change the jumpers for FSB and AGP.
Before changing any jumpers, power the mobo off completely - I've found that this mobo can get upset if you change jumpers whilst there is still power to the board - I had to clear CMOS to get the thing back to life once!!!! (meanwhile thinking I'd bust it!)
Yeah Krusty thanks I hear that too about this board. I've done all I can but still no success. From my understanding this celery chip 533 should OC to around 800 mhz. So far I'm running around 600. When I change FSB boot up frequency to 100 mhz the puter doesnt boot. SO at this point I'm running FSB group at 66mhz with the soft menu at 75 mhz. Here's the breakdown
66mhz= softmenu to be adjusted from 66-83 mhz
100 mhz=90-122 soft menu adjustment.
133mhz=124-155 soft menu adjustment.
The 66, 100 and 133 mhz categories are selected by 2 jumpers on the board. All I can select is the 66 mhz level which allows me 66-83 in the bios selection. When I set the jumpers to the 100 mhz setting the board will not boot. So either I'm doing something wrong or I have a cpu than cant make it to 800mhz. I thought maybe it was an autodetection problem but who knows at this point.
Well Krusty thanks for all the info. I followed it to the "T" and stiil no boot. I then placed a PII 233 cpu in and set it to the 100 mhz jumper setting.The board booted, and I was able to OC that cpu to 350 mhz. So I know the board and setting work. It comes down to this. Either I have a cpu that can't run in the 800 mhz range, or its my convertor card. The convertor card I'm using is also auto-detect without jumpers. Maybe I need a card that I can over clock with. I would like to thak everyone for their input. At least I know the board works. I do have a new convertor card coming so I will know then if this cpu can run where I thought it could. Thanks everyone!
I have the same board with a celery 533 @800
with no problem , it's a very nice board.
I think it's your slocket card. I have an IWILL Sloket II and got it at www.azzo.com
Try it I think you'll be happy with that!
have you increased teh voltage at all???
i had to run m y 566 at 1.75v to get it stable at 875...
OK, here's a thought - because the Soyo board attempts to POST at default voltage and at whatever FSB group you select, then ramps these things to what you set in the SoftMenu, if you get a slocket that has an on board voltage regulator, you should be able to give the chip more volts right from the start. Remember, though, the mobo has the %age voltage increases in the softmenu, so if it was previously set on +10% and the default for the celery is 1.5, the chip will get 1.65V - not a problem. However, if you set the slocket to 1.7V AND the softmenu to +10%, the mobo will juice it with 1.87V. OK, so the chip may be able to handle it, but be careful that you don't zap it with more than you think!
Ok before I go any further lets see if I have the right CPU. Krusty when you get a chance could you go to www.krex.com, click under the CPU category FPGA and look at the celeron II 533 chip and tell me if that's the right one. Well if my card doesn't have the voltage regulator on it I will order the one from Azzo.
I couldn't connect to krex.com, but I think our server's playing up this morning.
If your celeron looks like this:
Then it's a celeron2 and should be overclockable.
I can't find a piccie of the old celeron, but the socket 370's have a large metal block in the middle and are mounted on a black chip thing.... err, not quite sure how to describe it, but the dark green area in the piccie I posted is black on the old celerons.
CMonster has had a cel2 533 up into the stratosphere:
Why not ask him for some tips!
Yeah looks like I have a Celeron 2. Small chip on a big green board. Well I ordered a convertor card with a voltage regulator on it. This is as far as I will go with this chip. Doesn't work after that I'm going to step on it! hehe Not really but.... Figures I get a chip that won't do the specs. It does run nice at 600mhz. I guess I can be thankful for that. Perhaps I will go to the new Durons next. Since my first experience with the Celeron has been a little more than disappointing.
