Running OCCT will eventually error with an overtemp error, but the heatsink is only slightly warm to the touch (this same HS was used at a reduced RPM for my other C2D e6400 with no problems). With a Zalman CNPS 7000 running at full speed, Idle temps are about 45C in CPUID HWmonitor and OCCT status panel. I've increased voltages slightly on both the CPU and Mem, but the wierd thing is that I can't seem to get even a 5% OC without OCCT and Prime95 errors.Įverything seems to be stable at Stock speeds, but Temps seem high. I've read that the e4600 should be able to hit FSB 1066. Set FSB to 210Mhz and DRAM 1:1 (DRAM is rated to 217Mhz stock) and OCCT errors with code4 and Prime95 returns rounding errors. Reset to stock speed FSB 200 and DRAM 1:1. Since this MB can do FSB 1066, I tried setting the FSB to 250Mhz with the DRAM on auto set to 156Mhz (1:1 ratio was not stable - would not boot XP).

This was a great transition system when I first ugraded to a C2D e6400. I'm using it in an ASROCK 775DualVSTA with an old nVidia ti4200 and 1G Mushkin DDR-3500. I picked up an open box e4600 for a great price to use as a second system.
