I had a new E7500 cpu hanging around, and came accross an Intel DQ965QF board for $20 so I put them together.
It was working for a few days and then suddenly stopped and would not boot. (Long beep, then stop, restart with long beep again, then stays on, fans etc but no boot.)
After some research (beacuse I thought it was the ram timing or such) and checking all components, I found that the E7500 is not on the compatable list of cpu's (maybe because it is 45 nm technology, i dont know)
So anyone have any ideas why it worked, or can it still work?
Was there a bios upgrade on some of these boards, which alowed it to work?
I used to own the Intel® Desktop Board DP965LT and ran it will an Intel Core™ 2 Duo E6400. Later on I would look into upgrading it and even with the latest Bios it wouldnt accept any of the 45nm processors which would include the Intel Core 2 Duo E7500. The VID voltage changes from .8500-1.5v on the 65nm Intel Core 2 Duo's to .8500-1.3625v. So the DQ965GF which only supported the 65nm Intel Core 2 Duo's most likely can't clock the voltage down to the lower voltage.
Just been checking on ebay for compatible board for the e7500 duo, and found the e7500's are still selling for over $100/$160 here in Australia. I didnt realise they were still so expensive.
Sooo! if I assume I have not stuffed the CPU, any suggestions on a board (not too expencive) that I should look for, that would take advantage of the CPU. INTEL,ASUS, or GIGABYTE?
I have a winfast nvidia 8600GT card I was going to use as well.
Or should I take these questions to the M/Board part of the forum.
PS: I have found a few people that have had eE7500 45mn's working on older 775 socket 65mn's boards, so it was just luck my combo worked in the first place. most has said the CPU would be fine with the voltage difference. Hope they are correct.
