Max VCore for PIII 700's?

[Daniel R]

Hello guys:

I have a PIII-700E FCPGA processor. It needs a good kick of 1.9V, Asus probe shows anywhere from 1.9 to 1.95V but usually 1.936V, to get it at 1GHz. What is the highest voltage that I should run this puppy at? I have a fairly decent sized Al heatsink and fan on it, with a 120MM fan blowing inwards right above it on the casing. Here is a picture of Asus Probe:

Design maximum for coppermine is 2.1v. I have one running at 1.9v with no problems and it's been up for about 6 months 24/7 as a server. With a PEP66 it runs about 39c maximum with Seti load.

Tim, is the PEP66 the best socket heatsink for the space requirement? I think It's about time for me to get a good heatsink, perferably an Alpha. I just need a good one that will fit on my CUSL2 as well.

Daniel R - My P3-700 has been running 1008Mhz for about a month at 1.90v with a PEP66 on a P3V4X. Temp range using MBM shows 21C inside case and 32C idle for internal diode. Have run Prime95 Torture Test for 12+ hours with temps not exceeding 48C. I get a lot less temp increase when running Seti and that is why I use Prime95 for stability testing and burn in. The maximum core rating is 2.1v as mentioned but I would suggest that you not increase above 1.95v and keep the temps below 50C under heavy load. The max temp for PIII 700 is 80C.

I think the PEP66 is designed for cooling a flipchip proccesor on a slocket . The fan is located on the side of the Alpha rather than on the top. I use the Alpha PAL6035MUC for my 800E flipchi on a BX133Raid mobo. Idle temp is 28 degrees C
