Overclocked CPU, need some help

[FrozenLiquidity]

I finally managed to get my Pentium III 700E to run stabily at 868MHz.

First things First.

System Specs:
Pentium III 700E (SL3XM)
Asus P3B-F Motherboard
512mb PC133 RAM
GeForce2 64mb
SCSI card (with 2.o gb SCSI Hard drive)
MX300
D-Link 10/100 network card

P/M 13.5 GB 7200 RPM HD
P/S 30.0 GB 5400 RPM HD
S/M 12x10x32x CDRW/ 8x DVD
S/S 24x Creative

Ok, I am running the computer at 7.0*124=868MHz The PCI Bus is running at 31MHz The CPU Core Voltage is at 1.75


My problem is that when I overclocked it to 868, it seems to have periodic clowdowns. I could be playing Quake3 at 120+ fps and then it would go down to like 20-30 FPS for a few seconds and performance would severly drop. Then it would go back up to normal speed and it would be fine. It does this about 3 times every minute, and it makes 3d games unplayable. At first I suspected that there might be a slow RAM chip, so I tried each module individually, same thing. I have 3 sticks as follows.

A 256 MB DIMM
PC133 -07ns

A 128 MB DIMM
PC133WAB -7ns

A 128 MB DIMM
PC133 2CAS

I am unfamiliar with RAM timings and I wonder if it could be causing the slowdowns.

The problem disappears when I have my computer clocked to 805MHz(7.0*115=805MHz, CoreV of 1.70 and 38MHz PCI Bus)

Does anyone have an Idea as to what could be causing this?

I will probably be snagged by Socalgal for posting this, but noone seems to listen to my other post.

It could be that the limit is being pushed for that particular processor. Is there anything you can go to between 805 and 868 that will stop this problem? Also, just in case, I would try the OC with one stick of the ram out til I found out if one of the sticks was less stable than the others.

I did that, didn't you read the entire post? I think I said something about that.

Well, I figured this out. I set the Voltage back down to 1.70v and changed the RAM latency to 7ns (instead of 8ns) in the BIOS, I think this made a difference becasue the settings that the RAM was at before it said it could run at up to 124MHz, after I changed it it said it could run at 143MHz. WHen I loaded windows the problem went away and now I'm cruising just fine.

I think it was just the RAM latency problem though.

I will try for 931MHz this afternoon!
