I've got an i5-660 that I'm messing around with to see how high it can go for 24/7 usage under water.
So far I had quite a bit of an issue trying to get a BIOS that worked on the Gigabyte P55-UD3R. Now I've got one that works (more or less, still somewhat funky) but when using 8GB I get a bclk wall around 165 (4.3Ghz).
Oddly, it doesn't matter how fast the RAM is running, absolutely no issue running DDR3-2000 with 8GB but even if I scale down the memory (as low as 900Mhz) the bclk won't go any higher.
With 4GB I have no issues at even 240 bclk, though there are a few "bclk holes" like the old Nforce 4 FSB holes. 200 is perfectly stable, 205-209 won't boot, 210 is rock stable, etc.
Do you think switching boards (either EVGA P55 SLI or Maximus III Formula) would help or is it purely an IMC limitation on the i5-660?
The only reason I wanted to try a 660 was to get 4.7-5.0 24/7 stable with 8GB (required for a game that I play, at least, how I play it) for better gaming over my 4.2Ghz i5-750.
