How do you adjust the FSB on an ABIT BH6 running Celeron 333?

[Typh]

The BH6 has something called a CPU Softmenu in the BIOS that lets you User Define the MHz, multiplier, AGP ratio, etc.

When I select a 100MHz bus, the computer doesn't even boot or get me to the BIOS at all.
When I select a 66MHz bus speed, with a multiplier to get me 433 out of my 333, the BIOS always reverts back to the minimum the mother board supports, which is 233(66).

I am new to overclocking and would like to get my 333 up to at least 450, but how can I do this if the BH6 won't stick with my User Defined changes?

BTW, I leave the voltage at it's default of 2.0V.

Typh....welcome to the Forums. The Celeron 333...and almost all Intel based processors are multiplier locked. Don't bother trying to adjust the multiplier in the BIOS settings. You're on the right track though.

From documentation I've seen, the BH6 should have a wealth of FSB settings "Between" 66MHz and 100MHz. Without excellent cooling and proper settings, hardware, etc, 100MHz is a big first leap to make.

Check your BIOS again and focus on the FSB settings. Use your "Page Up" and "Page Down" keys to select different FSB settings. start low, check your temps in the BIOS often, and slowly move up. Of course...consider a cooling upgrade if your using a stock Heat Sink and again...take it easy. Good luck. If you don't have your user manual... this link will take you to Abit's manual download page:

Yeah, welcome, welcome Well ya probably don't have a wealth of options, but you do at least have 75 and 83 FSB options. First try 75. In the bios remember to set the 66/100 to high and disable speed error. Actually, I bet ya get'er above 500 MHz. with a bit of pushin

Yes, you should be able to run 75 MHz FSB without any problem. To reach 100 MHz FSB, you FIRST need to address the cooling issues. A better cooler is in order and you need to use a good thermal paste. Probably you need a couple extra case fans too. Once you have cooling under control, then bump up the CPU core voltage a little (no more than 2.3v). You ought to make it then. But, do the cooling mods first. I had a 300 Celly and a BH6 board that I ran at 464 for over a year. I had a fancy triple fan CPU cooler and used thermal paste, plus had to up the voltage to 2.2 volts.

NOTE: those of you that are used to overclocking coppermine CPUs, don't panic about the voltage advice, those old Celerons had much higher default voltage (2.1v... I think).

I actually right now according to MBM 5 have the 333 running at 455MHz.

I have it at 90MHz(1/3)S with multiplier at 5.5 (Low) and voltage at 2.30.

However, I get a message at boot up saying that the CPU is improperly configured and a selection to hit F1 or DEL. I hit F1 and it takes me in and so far it is stable.
I have played a few games of NHL 2001 and the temperature has not increased at all...38oC.

Also, if I go into the BIOS and even just quit without saving, it reverts back to a 333 and I have to set up the FSB, etc. all over again.

Any suggestions?

 

[Typh]

Oh yeah, I also after pressing F1 get a flashing message in the BIOS as it boots up saying:

SPD not found at DIMM(s) 1

???

 

[Typh]

Ok, thanks a lot for all the advice.

I have the 333 @453 right now:

FSB is at 90Mhz(1/3)S
I set the it to HIGH, as per your advice.
I have disabled the speed error thing, which got rid of my F1 or DEL choice...thanks for the advice here.
Voltage = 2.2V

Temperature is still holding steady and unchanged due to overclocking at 38oC...to add, I have a 5000RPM fan on it which may be why it hasn't started to heat any more.

Is this normal?

Are my settings normal?

The BH6 doesn't allow me to go over 2.3V anyway, and when I try the next highest FSB (95MHz) at 2.3V, it freezes up...so I don't know how to get it any faster even if I wanted to.

I guess I just want to know if my current settings are fairly safe and fine and whether the temperature not increasing is normal.


Thanks.

My version of the Abit BH6 did not have a 90 MHz FSB setting. It only had 66, 75, 83, 100, 103 (turbo mode), 112, etc. Also, do not set a Celeron 333 at 5.5X multiplier. It has already been explained to you that the multiplier is LOCKED. Set it to 5X and try again.

Maybe try flashing your BIOS with an updated version if you haven't done so yet?

Another trick with the old PII's and Cellies is to raise the L2 cache latency. This you can do also in bios. With the spd message ya get it sounds like you could upgrade your mem a bit. I bet your using very old no name stuff, right ?

 

[Typh]

The SPD msg I'm getting doesn't seem to affect anything.
It just flashes during boot.
One simm of the RAM I'm using is older (a 64MB one) but I do have 320MB RAM total.

The system seems to run stable, except when I try to run WWII Online (a pretty processor intensive game).

It locks up during load when OC, but when I reset it back to a 333(66) it loads fine. Only this game though, all other apps seem to run fine.
