Here's my latest endeavor.



I've been examining the E0 Stepping predicament with IP35 PRO for about a year now.
Here's is a link to my current findings.
TRP-IP35 PRO-E8600
Unfortunately the original thread regarding all of it is missing. One of my fellow staff members must have accidentally deleted it so my determinations from last summer and fall may not be available.
By the time all was said and done I had used a total of 16 different BIOS 18 files and performed 24 BIOS flashes using floppies as well as files throughout the process. I even pulled a couple of hot swaps.
I used 3 different IP35 PRO motherboards - one early and two late revisions, and a variety of actual BIOS chips.
You will see my findings in the linked thread.
I think that it has more to do with the actual BIOS chip. I purchased a brand new IP35 PRO - 1st revision with the original BIOS 10/11 chip. Well. 418 hours on it. That's new in my book. I flashed BIOS 18 to that chip and have it installed in my old, worn out, second edition IP35 PRO. Total success.
So far.

Bottom line is that the IP35 PRO is a fantastic motherboard but the BIOS versions that support E0 Steppings are flaky at best. So if you want to achieve 100% successful results from an E8400, E8500, (E0 Stepping of course), and especially an E8600, then it would be best to go ahead and invest in a current motherboard that features a fully operational E0 Stepping BIOS.
Cuz it ain't gonna get no better!

In spite of its problems with the newer CPU versions, I still haven't used a better 775 motherboard than the ABIT IP35 PRO.
