View Full Version : Help please, which CPU's do you think this board will support?
Okay heres the setup,
Its a Slot 1 440BX motherboard that has jumpers to set multi, up to 5.5,
as it is it can only run 66mhz FSB CPU's...but finding out the next revision of the board up supports 100mhz FSB with a jumper, I have decided to solder in the jumper that is missing to get 100mhz fsb...
But im wondering, if the board only has multi up to 5.5x, can I not use a cpu that has a higher multiplyer?
cause if I can get the FSB up to 100, Im going to then try using CPU FSB or softFSB to get it higher cause ive seen this BX chipset on other boards go WAY high...
BTW the board is a DTK PRM-00801 e0.......
thanks Laterz....
Use a slotket with jumpers and a socket 370 Celeron, then the multiplier won't matter.
Could you be a bit more specific, cause Im realtively new to the Intel scene...
And what about a p3?
A slotket is a slot one to socket 370 adapter (see link). If you get one that has jumpers, you can adjust the multiplier and voltage. Slap a classic overclocker Celeron 566 or 600 on that bad boy if you can get the 100 FSB to work and you suddenly have a 850 or 900 MHz system.

Cool, Thanks..
But I thought the multis were locked on Intel CPUS?
And does this leave the Pentuim III out of this setup..cause teh BIOS supports them...
Anybody?
I really do not want to buy a CPU with a slotket and have it not work
the multi's are locked on Intel CPU's therefore it doesn't matter what multi. you have set in the bios it will still work as long as the CPU is compatible with the mobo.
The P-III's will work too. Yes, the multipliers are locked, but what I meant is the slotket will usually allow a higher multiplier to work then what the BIOS technically supports. The key here is if you can get the 100 FSB to work. If you can't, than a P-III will be a waste of money if it'll only run at 66 FSB. If you're stuck with only a 66 FSB, then you'll have to settle for one of the faster 66 FSB Celeron (I think 766 was the fastest one made).
Oh ok,
Cool Thanks...thanks very much...
Hehe...this is gonna be fun...
Got any recommendations on a Pentuim 3? (Speed)
The P-III 700 is a good overclocker that will do 933 almost guaranteed. My old 700 ran perfectly stable at 1050 and actually would benchmark at 1071, but you don't know yet if you'll even be able to run at 100 FSB, let alone anything higher. I'd get a 600 Celeron, that way if you're stuck at 66 FSB, you still have a decent system and if you can hit 100 FSB, you'll be able to run 900 MHz. You don't want to spend much on this system. You'd be better off making this a budget project and then save up for a P-4 system.

If you are getting the Celeron and must choose one with a 66 MHz FSB, get the 733 or so. The C0 stepping is better than the B0 stepping. I've had 4 different 733s. All of them would break 1 GHz with the stock heatsink and all of them could be coaxed to break 1100 MHz with good ventilation and cooling. I am still running a couple of them at 1066.

Sorry about stringing this out. Another reason that you should want the C0 stepping over the B0 stepping is that if you ever want to mod the voltage through the VID pin, the C0 stepping provides more options than the B0 stepping without being forced to very high settings.
Dave
I must admit the cCo stepping is good and I'm impressed with your Celeron 733 overclocking success, but not everyone has been able to get that much out of those CPUs. Angry has no FSB options. He's hoping to mod the board for 100 FSB. The Celeron 733 has a 11X multiplier. Trying to hit 1.1 gig is not a good gamble.

Well, batboy, I have to agree with that slant. I would also not buy a 733 if the only speed options are 733 and 1100 because the 1100 is a bit stretchy and probably odds against. I think hitting 900 MHz from a 600 MHz CPU is easier probably odds on.
Guys dont worry aboutthis going on...the longer the more i learn the intel side of things...
I think what I will do is buy a slotket with jumpers as posted and "borrow" the Celeron 500 (7.5x66) out of my sis's Compaq and throw it in and see if it works if it does then I guess I will know for sure I can get a Celeron....
As far as I know, and can tell soldering in the jumper will give me 100fsb because both versions of the board use the same BIOs...
so its eithera Celron 700'ish or Pentuim 3 700....cause Im hopeing that I can getthe board higher with CPU FSB..if not then I guess I will have to see if I can purchase an old school Turbo PLL device....
Laterz....wish me luck!
Unfortunately, the Celeron 500 is the old style Celeron and is not a newer Coppermine Celeron, so it really won't tell you much. Plus, the Celeron 500 will undoubtedly not overclock to 100 FSB.
batboy is definitely right about that...I went through several cele 500's and the best I could get out of any of them was 600 with voltage increase and 563 (75 FSB) w/o voltage increase. Also depends on the board too
Well...I just want to make sure that it works....
For my own assureance....
Not all slotkets will accept both the old Celeron I and the newer Coppermine CPUs. My old Abit Slotket !!! had a jumper that was marked Celeron and Cu, the Celeron setting was used for the old style CPUs and the Cu is the chemical abbreviation for copper and that setting was for the Coppermine P-III and Celerons.

The only difference between BX and the LX chipset that proceeded it was that BX was introduced soley to provide the 100MHz fsb that the (then) new P2-350 and 400 required. ALL BX boards will do 100MHz fsb!
The fsb setting is read from the cpu id information present on all modern Intel chips. The board does not need the jumper added to run 100MHz. Simply inserting a 100MHz fsb processor will automatically make the board run at 100MHz. The jumper is to force 66MHz fsb processors to run at 100. If you wish to run a 66fsb chip at 100 you will need to add the jumper (and hope it works).

Ah ok so I see..Hmm....
Well...Ill just grab a 100fsb proc.....I guess....hmm...
Ah well see....
Larva might be right about it automatically using 100 FSB if the CPU uses it. Here is a link where you can download a manual for your mobo. Maybe check to see if it supports 100 FSB CPUs before buying something. You might also be able to download an updated BIOS that might support more multipliers too.

If you don't have a 100fsb processor you can use a slocket with jumpers on it to lie to the bios about the default fsb or even use tape over some of the pins on the slot 1 interface to the motherboard. It's a pain in the *ss to do but you can vary both cpu voltage and the fsb parameter by covering the appropriate lands on the cpu. I read about this trick in the article on SL2W8 2v P2-300 cpus on tomshardware. I used this trick to run many of the SL2W8's I sold at 450MHz, with my personal example stable to 504 before the cache chips gave out.
Sorry Ive been away...
Well its like this.. I have d/led more thean one manual...
Finaly found the revision of the board which is RB....
The reason i think I can solder in the jumper is because the next version of the board after RB has it..but both versions use teh same BIOS and as far as I can find the same PLL chip...
The manual says P2...but the BIOS says p2, p3, and celrons...
Im personaly haveing fun though getting a freaking BIOS chip in this thing..this is whats really slowing me down...
Its been missing its BIOS Rom since I got it....
Wish me luck....Ill need it...
