Pentium II 450 Overclocking Question.

[ShaYmuS]

Hello

I have a pentium II 450 with a Gigabyte GA-6BXC Motherboard. I have two 128 meg sticks of ram. 1x 128 pc-100 and 1x hyundia 128 pc-133.
I have overclocked it up to 504mhz by uping the fsb from 100 to 112. I tried 133 but it didn't POST.
Everything is running fine except sometimes when i play counterstrike it brings up an illegal operation and crashes back to windows. I believe this is from me overclocking because its never happend before.

Could running my pc-100 ram at 112 be causing these problems?
If i took that stick out and only left in my pc-133 stick should everything work fine?
also if i just had my pc-133 stick in could i put the fsb up to 133 without stuffing up all my pci cards?

My System Specs are:
Pentium II 450 @ 504
Gigabye GA-6BXC Motherboard
1x 128meg pc-100 No-Name Brand Ram
1x 128meg pc-133 Hyundia Ram
Nvidia RIVA TNT Agp Video Card (Diamond) @ 112 core, 125 mem
Soundblaster Live Value
Surecom EP-325 Ethernet Adapter
Symbois 8100S PCI SCSI Card
Dodgy ISA SCSI Card for scanner

Thanks in advance

Yep, yank the 100 and give it a whirl. Only the best 100 memory will run at high speeds. Give it a whirl. It's easy and low risk

I see four potential problems for your instability. First is maybe the PC-100 RAM, the second is those ethernet cards sometimes don't like being overclocked, but what I really think you ought to try is to improve cooling. Last, after you improve cooling and find out it isn't the first two things I mentioned, then you might need to bump up the voltage.

[Yodums]

Is there anything between 112 and 133 because that's 600mhz and thats a big jump. What I can think of is that your FSB is too high ... Your PC 100 ram(Can be easily found by just trying to make it post without the PC-100) or it won't post without enough voltage.

Good Luck.

Yea, could be the PC100, Ethernet card, or cooling, but it's also possible that may just be the limit. I had one of those once, and I had difficulty hitting 518--- it was only stable at 504 and that was WITH a voltage bump. That is the upper end of the PII's... that may be as high as you can go. They weren't made to go too much higher... plus it's a Katmai and those just don't oc well period.

Get Seti Spy and check if it's a Katmai core if it is you some what reached the limits of that chip.

like yodums said, you might need to up the voltage, don't know if the board has that option in the bios. if it doesn't you can always do the vid pin mod.

don't know if you can adjust the L2 cache latency from the bios, but as a last resort, try using wcpuid version 3.0c to lower the L2 cache latency, and use softfsb to overclock in windows. wcpuid 3.od always locks up on me whenever i change the L2 latency on my pii350.

with my pii350 i had to up the voltage to 2.2v and lower the L2 cahce latency to 3 from 1 when using crucial cas2 pc133 memmory. oem mobo, so nothing in the bios :\ but after those last tweaks it ran stable.

if it runs too hot, try using a cpu cooler program if you haven't already use one. Rain 1.0 has pii optimizations, and it doesn't eat much resources. Every little bit helps

I believe Rain is an idle cooler.. Why cool your comp when its idle doing nothing :)

I've tried a couple of those software cooler programs in the past and was very disappointed with the results.

same here

[Dtown]

How can you cool Hardware with Software? Makes NO sense! I agree totally with you guys.

[Yodums]

The programs disable all programs running I'm guessing and some Windows thing running in the background so its sitting there doing basically nothing.

[Dtown]

Who would want there PC to do nothing!!!!!! That's crap. :mad:

[Yodums]

... Why let it sit there doing nothing when you can CRUNCH SETI!
