So after replacing an e5200@3.4 with an e8400 stepping c0 thinking I could get it at least to the same speed at stock voltages, I can't get past 340x9 (3.06) without failing a prime95 test after an hour. It wouldn't even boot at 378x9 (3.4), whereas I could boot into windows with the e5200@3.6 with stock voltage and cooler (same motherboard).
Since I have a crappy old asrock mobo (n73v-s) with the 610i chipset and no vcore adjustments, I thought that it simply didn't like anything above the rated 1333 fsb, but i just tried the stock speed as 375x8 (3 Ghz) = 1500 fsb and it didn't get any errors running the large FFT prime95 test after 30 mins (still might not be stable, but I was surprised it booted). I have the ram downclocked to get the1:1 ratio so I don't think thats the issue here.
I suspect I just got a crappy chip that needs more voltage, but what do you guys think the issue is? should I revert back to the e5200@3.4 🙁?
Edit: Oh I totally forgot, temps with the e8400 seem too high with everything at stock; 63 ºC cpu and both cores at 80 ºC each running prime95 for an hour. At idle they are the same as the e5200, cpu @ 33 ºC and each core at 43 ºC.. I'm so confused!
