Anyone succesfully OC a PII 350..?

[Guyver]

Just thought I'd add a little to the mix here. I had previously been running with 2x64MB PC100 SDRAM that I had thought I had been jipped on. I had paid $88 apiece for these about 4-6 months ago. Turns out that the memory on these puppies is 6NS - about the same that is on the PC133SDRAMs. Only difference I can tell is the little extras they now put on to stabilize the memory at 133Mhz on up. Found some advertised guaranteed up to 148Mhz. (Siemens) - Check out pricewatch.com for the listing under PC133 128MB SDRAM.

I purchased a 128MBPC100 from the same vendor I had originally bought the 64MB from and lo and behold the memory is only 8ns. Can't go above 112Mhz FSB. I'm sending it back and ordering some PC133SDRAM.

Should have my PIII-450 here tomorrow. Hoping for 580.1 or so @ 129MHz FSB!!!

Later.

Thanks all,

So it looks like the only option in my case is to either clock the bus at 112mhz or buy 2 PII 400's

Oh well,
Thanks again,

Thanks for clearing that up Jake. Now I'm just wondering if I could get away with this on my PII-350 Compaq Deskpro here at work...

Semantics... anyway, it turns out that I have one of the older processors. Mine will boot and run at 450. I need to work on the cooling though. It starts rebooting itself after about 20 minutes. Runs solid as a rock at 400 however, and my voodoo2 cards seems happier at 33 MHz PCI clock. Everything ran ok at 112, but by increasing the processor interal clock by 8 MHz, reducing the FSB but 12MHz and reducing the PCI bus clock by ~4 MHz, I got a 30% increase in my Falcon frame rates. Will wonders never cease? Thx Kruzin.

Hello,

I bought my 350 last year, just before the infamous Celeron 300A were released for about $500 ! Since then I have been using it at 4 * 103 on a ABit BH6 board with no problem.

During the last few months however my happy configuration started to rattle and tear apart. I can no longer get it to work stable at these frequencies. I hav frequent crashes of Netscape, Explorer or Sound Blaster Live software. If I clock down to 400 MHz these problems disappear.

Who knows, maybe it is the additional heat of the summer, or the chips really AGE when we overclock them. Is this possible ?

Hi Oric,

About the heat in the summer, I bought a Celeron 300a in February and clocked it a few days later to 450 MHz. It worked great for a long time until a few weeks ago. I couldn't be using Internet Explorer for more than 5-10 minutes without getting some kind of error message and Explorer crashing. At first, I thought that I had some kind of a virus or something, maybe from all the stuff that I had downloaded. However, I do know that the computer, which is upstairs in my house, is the hottest room here. During the winter, it was very cool and thus no problems. I wondered what would happen if I turned it back down to the original 300 setting. And yep, for the past two weeks, I have not had a single crash at ALL! Now I definitely know that heat was the problem here. I know only have two options:

1. Move the computer to the coldest room in my house, which is the basement, and clock it back up to 450 or,

2. Get better cooling in my computer case wih more fans, since I am only using the retail heat-sink and fan that came with the CPU.

Hope that clears up the issue about the summer heat. I do not think that your chip is AGING, at least not that fast.

SteveC odds are yes. i ah traded a cpu for one out of a compaq desk pro at my dads work and it is one of the older unlockable ones. check the numbers on the top of the cpu. it will give you an idea of when it was made.althoue i dont think you will be able to over clock it in the deskpros board. becuase thire is no fan in the system and the cpu sits under all the drives and also has no fan on the heat sink. hey that sink comes right off too with just a screw driver.

hope this helps. hey worst come to worst buy a new one swap it with the one at work. over clock the crap out of it and if it blows up trade it out again and let tech suport at work fix it up.

its here now only if avp worked. but hey mech 3 looks great.
