Hi there, I was testing my Q6600 + TRUE + SlipStream 1.900RPM on a Gigabyte EP35-DS3L board. PSU is an Topower 520w, HD4850 [nothing to do with this...], and 2x2GB SuperTalent 800mhz + 2x2GB Mushkin 800mhz.

So, I had 3.6GHz @ 1.55v. It had 20h in Blend on Prime95. I've put the test with Thread's manually setted in 4, and got an error.
I started lowering frecuency, to 3.1GHz @ 1.55v, and it continued to be unstable.

Then changed to 333x9 [3GHz] @ 1.4v.
6 times, 4 threads, standard -> Error.
Standard, 6 times, Auto threads -> OK.
High, 7 times, threads Auto -> OK.
Standard 7, 4 threads -> error.
Standard, 10 times, threads Auto -> OK.

So, is it really unstable or it's just setting 4 threads the problem?
