Abit SE6, overclocking P3 800E, stuck at 1Gig(125fsb/3:3:1), need 4:4:1

[Henna_Ojisan]

I'm stuck at 1000mhz, running a P3 800E at 125Mhz FSB w/ 8x multiplier. Currently 3:3:1, but need 4:4:1 to go higher than 1gig. Won't boot at 125Mhz FSB w/ 4:3:1 but will with 3:3:1???? Anyone else hit this wall and make it past?? Please let me know what you did. Heat is not an issue, cpu temp is 22 deg. C. at 1gig. with 100% load.

Me again... This is for those of you with the same issues, I pushed my core voltage up, and had no problems. Currently at 1.95 v and running at 1040 stable, no probs with temps yet...Posted 1066, but I'll have to cool it more to get any higher.

How did you choose 1.95. My SE6 won't let me choose more than 1.90!!

What is the version of your BIOS?

Thanks in advance.

Abit SE6, overclocking P3 800E, 1.95 v core

I've got the older SE6, and I'm running the VK bios (released 10/31/2000). At one of the higher FSBs, I saw 2.0v, but when running at 130 mhz FSB 4:4:1 (1040 mhz) my limit is 1.95. This is by adjusting everything in the BIOS manually... Good luck!

Weird, I can't get more than 1.9 volts.

How about other SE6 owners??

I didnt think a bios update increases the core voltages!
What cooler are you using to get 22 degrees C at 100% load, air, water ?

I'll trade you PIII 800e's. You can have mine (cb0 stepping) which wont go any higher then 960 stable. I think I could get her a little higher if I could get more volts out of the board. I cant get anymore then 1.9v with my BE6-II.

Sorry, no way I'm trading this chip!!! Just installed peltier, and water cooling, chip will boot to windows at 1160 but locks up on occasion, stable at 1120. Chip temp idle at 1120 is (-10deg C.) and 100% load is 5deg C. Using less voltage now than before and booting higher. 1096 is 1.85v, and 1120 is 1.9v. If you want to know, here are the s-specs and stepping: SL4MA and cCO, 800E made in the Phillipines.

Well, I just reinstalled my 50w peltier. Now I can boot in @1000mhz. It seems to be stable. I'll do some gaming and it seems to run ok. although if I run any cpu stress programs it will lock up after a few minutes. I know if I get a 72w peltier I could get her 100% stable now! It seems to run alot cooler then it did previosly with this peltier. Although I am using a different case.

The highest I tried getting into windows at was 1024 and it booted right up. But would lockup as soon as I would start any thing cpu intensive.

I've got some hope again. I had given up on this chip, But now I think i'm gonna get a bigger peltier now and see what happens.

To answer Chris,

There are sometimes different core voltages allowed by Abit through their Softmenu. My SE6 has the ability to hit 1.9 volts with the VK BIOS. If I use an older BIOS the most I can choose with my cBO PIII700 is 1.85.

I think that the way Abit wrote this there is just a certain amount of headroom above the default. So if I want 1.95 volts I need to rewire my CPU with the wire trick to 1.7 default. At least, that's my theory.

Also there are posts on the web concerning more voltage options with some of the beta BIOS that Abit has released. The only beta for the SE6 that I can find reverts to the 185 max voltage.

Other manufacturers are different. For example, MSI allows voltage selection with there add on Windows overclocking program.

I wish someone could hack the Abit program to allow voltage changes from Windows or DOS. The only program that I have found is the Oda program and it doesn't seem to give me access to the core voltage. I tried to change the RAM latency on the fly in Windows with Oda's program - it resulted in a crash!
