are celly coppermine 633's locked?

[dpopiz]

guh I've been battling with this new system I'm trying to build for a while now.
I bought a celly coppermine 633/66 and a biostar m6vcg off fs/t.


I was never able to get it to boot or even generate beep codes, but I just realized today that this mobo is so old you actally have to set bus/multi with jumpers

multi:
2x-8x

bus:
66-150MHz


anyway, the celly is supposed to be 66x9.5, which this mobo doesn't support. originally the multi was set at 6.5x and when I changed the bus to 66, it came on and gave me a beep code finally telling me that there's no mem in it. so then I changed to 8x and it gave me no beep code. then I changed back to 6.5x. NO BEEP CODE ANYMORE. I cleared the cmos and tried again and tried lots of different multi's but I can't seem to get it to give me a beep code again like it did that one time.

first of all, is the celly locked for either bus or multi? if I don't use the right one should that mean that it won't initialize at all? why did it give me beep codes that one time at 6.5x but it doesn't anymore?

As far as I can remember, Celeron Coppermine processors weren't locked in any way - actually, they've been referred to as some of the greatest overclockers ever, I remember seeing once about a guy who did (or at least claimed to) take his Celeron 566 to 933 MHz with just a larger heatsink, almost 80% of clock gain...

Yes, they are most definitely locked. Multiplier locking began in the earlier generations. (The FSB is not locked.)

In these chips, the multiplier was locked at say 8.5 or 9.0 at a 66mhz FSB that was not locked, so you could usually run at 100mhz and get quite a NICE overclock. So a 633 locked at 9.5 could probably run at 950mhz on stock cooling.

I don't see that easily obtained potential i.e. 35% overclock, anymore.

Yup, but, was there a multiplier on chip that converted to a Higher multiplier(9x in this case)?

Whoa, thanks for the correction - guess I just learned something more.

werd. i had a celeron 566->1062 once

I'm not sure exactly what you mean... The cpu's are locked at one specific mulitiplier... i.e. 9.5 for this cpu.

I'm not familiar with the particular motherboard in question... But chances are that it was ignoring the jumpers altogether, since it read the multiplier off of the cpu.

I don't know why dpopiz was getting the beep codes, though. Might want to try reseating the RAM modules. Although if it seems to work fine now, I probably wouldn't worry about it. *shrug*

wingnutz: re ram:

I don't have any sticks in there right now because in another thread where I was asking about the beep codes they said to pull out everything including ram and you should still get beep codes if the cpu is working.
