Help w/PIII-700 O/C -Weird Problem

[nino]

I'm running a PIII-700 in the MSI-6337 board (i815e). It boots just fine into Win98SE at 1.6 volts at 933Mhz. After a while (or especially in Q3Arena) the system will hang. No matter what I do (increasing voltage to 1.8) the system is just as UNstable as it was at 1.6v. This is weird to me because I've always (6 cpu's) been able to add some stability due to increased voltages to the core but not with this one. I've added heatsinks to the clock generator and chipset. I mean I can boot into Windows98SE and run for an hour at 1.6 volts (default is 1.65) but no gain in stability by increasing the voltage.

Has anyone else had issues like this? Should I be looking at things other than my CPU? I have an Alpha FC-PAL35T heatsink and the temp doesn't really change at higher voltages either.

What is this burn-in that I keep hearing and does it REALLY work?

I have a
SB-Live
Promise ATA-66
Ethernet adapter
Guillemot ProphetII-MX
30GB IBM 75Gxp ATA100 running off the onboard ATA100

Thanks in advance

If you can, try increasing the I/O voltage. It should be around 3.3v by default. Increase it by 0.1v within the bios.

I should have mentioned that I tried that also. I went up to 3.5v and the system behaved the same at 3.3 3.4 and 3.5.
Thanks for the reply.

Oh yeah, one thing that might also be important.

I was able to boot into windows and run for a few minutes at over 1 Ghz. I shutdown after about 5 minutes. I did this to see if it was my CPU or something else. I'm pretty sure that it isn't but then again I haven't had ALL that much experience.

Hope this tidbit helps

I have the exact same setup but I can even boot it to 933. It's a cBo chip, I think i got a dud though, oh well. Whats your temp? my 6337 gives me really high readouts. I wouldn't trust the temp readings that much.

Hi Cracker099,
I just tried something out. I changed my RAM from my Kingmax PC-133 (Ball Pin Grid Array -really small chips) High Density 7ns to a generic w/Micron chips and I was able to Quake. I'll get back to you to tell you how things are going. I've got to disappear for a few hours but when I get back I'll let you know if memory has anything to do with it or if I'm still SOL.

Hey Everyone,
I'd like to PREMATURELY report that I got through an entire Quake session...something that I couldn't do before. This makes me really optimistic. I could only get into Quake for about 1 minute before crashing and I just got done playing for 10 minutes and no hangs at all.

I'm guessing that the i815e chipset and this board don't like the high density memory. I've got to figure out what to do with my Pc-133 Kingmax.

AGAIN, this is premature because I haven't done any significant testing but this is a step in the right direction...

Man I got some generic ram, I hope thats not the problem because I don't have money to get some high quality ram.

Hey Cracker,
Yeah, I get the really high temps also but I don't sweat them anymore because I realize they are useless. Well I've been running all day without a single hangup so I'm going to conclude that the memory is the issue. I may be back saying the opposite but I've gotten further than I've ever been able to with the Kingmax.

Cracker,
The Kingmax IS really high quality but the chipset doesn't like it at 133 for some reason but I've got generic memory that uses Micron chips that it DOES seem to like so you might be o.k. with the cheap stuff. It IS possible that it is your memory but it also could just be a bad CPU. I know...not much help.

I have to change the jumpers in my MSI board to get to 133. I would try taking out all the PCI cards (they might be sensitive to the overclock) and see how high you can get the system to run with the jumpers set to default and increasing the FSB (you can go up to 132 before you have to change the jumpers to get 133). Your hard drive will need to be able to handle the increased PCI speeds too. IBM's and W.D. do pretty well up to about 42Mhz in my experience but please don't take my limited experience as gospel.
Good luck...

Another example of why using HIGH quality ram... is esential in an overclocked system..IMO.
