I just purchased a 1 gig slot P-3 Sat. Retail box. Put it in Abit BE6-2 mobo and oc'ed to 1140. Would do 1170 and run Windows until I played a game of Uneal T. After about 1 round I got either a freeze frozen screen, no control or I got thrown back to desktop. What is that a sign of? My V card will handle these speeds cause I have had it above this b4.) 1140 was where my computer ran stable without problems during long games of UT. Temps, at 1160 never went above 41C, that I noticed, so the processor stayed cool.
1st problem running at 1140, I noticed that my drives,
especially my LS-120 was real slow and unresponsive. Then noticed my Firewire ports were not working. Checked all the numbers and found my PCI buss was low, 1/4 divider equalling 28.5 mhz. Went to a 1/3 divider and got a 38 mhz PCI buss speed.
I had upped my Vcore voltage to 1.75 volts hoping that would help. It didn't. I am still running Vcore at either 1.75 or 1.8 v. Processor stays just about as cool.
Wooe was me! Started getting Checksum errors. Crashed my computer several times before I got a handle on it! Lost my CD Rom drives and had to reinitialize my BIOS several times. Figured my PCI buss was too high at 38 mhz.
Back to 1140 and 114 fsb speed divided by 1/4, still no go on my LS and Firewire. Although the Firewire card and LS drive did behave at 115 fsb.
This got me to thinking. The processor running extremely cool, but the L2 cache would not be cooled much from the stock Intel heatsink and fan. 1st question I wondered about; Was the L2 cache overheating causing my problems after a certain time in UT?
I had an AMK 2X60 heatsink ordered. I thought maybe it was a good idea to put it on the 1 gig and see if that helped my computer become more stable at 1150. ALL I needed was 1 more mhz of fsb speed!
AMK came today. 1st I tried to remove the factory pins by using a small screw and pushing the pins out as described at Overclocking.com. I didn't have much luck trying this as it seemed to take *much* more pressure than I was willing to put on the pins to remove them. I have a fairly well equipped shop, so I drilled out the pins on a drill press. Was another way described to remove them, if one had the nerve. I had more nerve using the drill press than excerting all the hand pressure it would require to remove those nasty pins!
Anyway I didn't have any problems drilling out the pins. I never touched a thing with the drill bit, other than the pins themselves!
I removed the tape from the AMK and applied some Radio Shack thermal compound and mounted the heatsink to the processor. Good
All that is left is to install all this back into the computer. No problem!
Fire up the computer expecting it to start Windows at 1140 with 1/4 divider. It gets to Windows and hangs! It did it a second time.
Huum; What's wrong here? It ran fine b4!
I'm getting nervous! Did I kill my processor with some static electricity? I kept myself grounded while working with the processor. Constantly touching a nearby grounded copper water pipe.
I drop my oc'ing back 110 and do a 1/3 divider! Windows starts in safe mode! I immediately restart in real mode.
My 2nd question is a real killer; What is going on here?
After 2 hours testing different oc'ing combos, I find the best my processor will now do is 1100 with a 1/3 divider.
Problems showed up on starting Windows, 1 checksum error, 1 scan disk error, hangs, blank screens! The checksum error I understood, PCI 2 far out of time, at 1120, 112/4 for a 28mhz PCI speed. However I also got a Windows Protection fault at startup trying 115/4 for 28.75 PCI buss speed! Now this was the speed wanted, as both LS drive & Firewire card would work here!
Frustrating! Put on a new and better heatsink and fan and then get less performance!??!
Was I right in assuming what I did about the L2 cache?
Any comments?
