Max Mendocino speed & core voltage?

[jkersenbr]

I have an aging 366 that runs Win98 and everything I thrown at it rock stable @550/2.1v. It runs reasonably cool under my GlobalWin FEP32 (100F under normal use, 130F during the Q2 Crusher demo).

But if I up the speed any, I start getting some instability. 566(103x5.5) and 577(105x5.5) start making more Invalid Page Faults than normal at any voltage I've tried (up to 2.3). It will boot into Windows98 at 605(110x5.5) 2.2v, but is quite unstable. 566 runs cooler than 550, only hitting 120F under the Crusher demo.

I don't think RAM is holding me back. I have a stick of Kingston PC100 that I've run at 140 CAS2 before without problems.

My questions:

How fast can the Mendocino core go without peltiers, watercooling, liquid nitrogen, etc? Is 550 about the limit?

What is the highest reasonable core voltage for the Mendocino? It's not like my machine is up 24x7, but I don't want to use up the entire life of the CPU in the next few months.

Would a better heatsink/fan (like a GORB) help my chances at upping the speed? Since my system hardly ever hangs, it doesn't seem like a heat problem to me. It just seems like 550/2.1 is as far as my chip wants to go with good stability.


Thanks for any info.

your 366a with standard type cooling,is near its limit at 550.Instead of trying to liquid cool it,spend that money on say a p2-cel(633).What mo/bo do you run?

I have a P3V4X. Yeah, I know, a lot of mobo for a lowly classic Celeron. (Kind of cool to be able to run a 100MHz FSB and 133MHz SDRAM though!) I stumbled into a killer deal for the board a few months back and decided to stick my old Celly in it until I could afford a PIII or C2.

The guy I originally bought my 366 from had it on a BX-based Abit (don't remember which model) and sold it to me with a CPU Stability Test Certificate @ 605. Makes me wonder if the VIA Apollo Pro133A chipset just isn't as friendly to classic Celerons as BX's are...
