Cel633 OC'd to 792, and rising...

I want to take a moment to thank all the helpful posters that gave me some excellent feedback on upgrading and OC'ing my BH6 board.

I picked up the CPU yesterday - retail cel633 - and using an ASUS slot adapter and the stock HSF I've had my system rock solid overnight at 792! I'm going to try for more tomorrow, but I have a feeling that my matrox millenium (2 megs!)+ voodoo2 card will affect higher OC'ing...anyone know someone selling a half-decent videocard (i.e. TNT2, Voodoo3, etc...) in the Toronto area? I can't see the need to upgrade my videocard until the next-gen chips come out (NV20, Rampage, Radeon2).

On another note, I read a review on the 'Agilent Arcticooler' HSF and it sounds pretty sweet. I don't think it's being sold retail at the moment though.

If your trying for 950mhz or 100 FSB then the older (or newer) graphics card won't matter since you can select the 2/3 option in the soft menu for AGB/FSB entry. Keep reading about a replacement HS/Fan because you're probably going to need it. An Alpha Pep66 with Artic Silver or Circuit Works equivilent (especially if you got it free) are my choices. What voltage are you running. Remember you can flash the Bios using the voltage trick to get higher voltage.

yeah! my633 now runs stable at 950... i was running it at 790 at std. voltage.. but now its at 1.80volts. i also hava a bh6 so with the newest bios update its a piece of cake

if i can do it anyone can......

PS.
is 1.80volts safe? it seems a bit steep to me... but at 1.75 i get a smaal amount of blue windows-screens

Nick, Im running at 1.65 volts so i'm happy about that - but as Slax mentioned, Im expecting to have to jack up the power to keep it stable at higher clocks.

What's the voltage trick you speak of? My bios is version SS...

How can you get a Circuit Works fan for free?

its an SS bios......
the voltage tweak is right there in your bios..... with the cpu-overclock thingie... on the bottom
another off topic question..... does your bios have a spellin error? with me it says SYTEM instead of SYSTEM... LOL

The Circuit Works silver conductive thermal compound can be otained by filling out a survey. Do a search for "Chemtronics" in the hot deals forum.
What's the highest voltage you can get? 1.85? 1.90? That's probably high enough, but here's the Bios flash trick just in case.

THE ABIT BIOS TRICK; for Abit BX6 and BH6 era motherboards.
Before you do anything else, Enter your Bios (enter ?Del? key while the computer posts) and write down your existing Bios settings or use ?print screen? to print them out. Sometimes you have to exit and re-enter the Bios several times to ?Print screen? each page.
1: First of all, download the desired Bios ?*.bin? file and flash program ? ?awdflash.exe?.
2: Execute the downloaded ?*.exe? Bios file to expand it for use.
3: Format a diskette with the copy system files command or go to the Dos prompt and enter: format a:/s (Don?t take a chance on an old floppy that you formatted 5 years ago!)
4: Copy the ?*.bin? file you got after executing the ?*.exe? Bios file to the floppy.
Write down the name of the .bin file: example -- Bh6_kg.bin
5: Copy the ?awdflash.exe? program to the floppy.
6: Reboot the computer.
7: Now enter your Bios again.

Step 1: Set your CPU Bios settings to default. (Don?t run overclocked or out of spec.)
Step 2: Set voltage to ?user defined? and then set your voltage to the maximum you have available; usually 2.3 volts for CPUs with 2.0 volt defaults. (older celerons) or 1.7 volts for Celeron IIs for example.
Step 3: In the Bios Features Setup; set the boot sequence to: ?a,c,scsi?. if necessary,
and enable " Boot Up Floppy Seek" if necessary, to boot to your floppy.
Step 4: Save settings and restart.

Now the computer will start from the floppy.
When you are at the ?A: prompt? in Dos, you are ready to flash the Bios.

1: Type ?awdflash? and the flash program starts.
2: Type in the name of the .bin file (i.e. BH6_kg.bin) - or the one you wrote down previously; and press ?Enter?. The Bios flash screen comes up and provides you a blank to enter the ?*.bin ? file.
3: The flash program will ask you if you want to save the old Bios - answer ?yes?!
4: Save the old Bios to the floppy with any name you like - I use "old.bin" - and then press ?enter?.
5: After the flash program has saved the old Bios it will ask you if you want to program the Bios - answer ?NO?.
6: The flash program will now terminate and return to your floppy drive.
What you have done now is to save your old Bios - and you now have the opportunity to flash back to the previously Bios again. When you do the Bios trick as a single command line with all the switches, you don?t have the opportunity to save the Bios at that time.
Now you are ready to trick your Bios voltage settings!
7: The trick is NOT to start the flash program as you did previously: let?s say you have downloaded the ?kg? Bios and now you have a file called Bh6_kg.bin on your floppy - Right ?
8: Type exactly as follows for the BH6 ?kg? Bios: awdflash.exe bh6_kg.bin /py /sn /cc
9: Another example ? for the BH6 ?jj? Bios: awdflash.exe bh6_jj.bin /py /sn /cc
Now press ?enter? to begin. It takes about 30 seconds. Later press F10 to exit program when all activity on the screen stops.
10: Restart and go into your Bios settings - now you will see that the higher voltage is now the default. If the ?new default? is 1.7 volts, you will now be able to reach 1.9 volts!!! Don?t forget to reset your Bios settings before booting into Windows or you might find Windows installing ?Com ports?, etc. that you don?t want installed.

Whoa Nick, that's some major detail you go into there! Fortunately it looks like I wont have to go past my BH6 1.01 SS voltage limit to OC because I am now running almost perfectly at 950!! It's at 1.75v and I ran it all night with Prime95 torture test...and this is with the stock HSF! I still have to test it out with Unreal/Q3 so we'll see if it sticks, but Im surprised I got it done so easily!
