Hello all!
I put together a system with:
MSI 790GX-G65
Phenom II X3 720 BE
4 GB (2x2) Corsair XMS3 DDR3 1600 MHz RAM
OCZ700XSX PSU
Arctic Alumina + Coolermaster Hyper 212+
Coolermaster HAF 922
Intel X-25 G2 80 GB SSD
EVGA GeForce 512 MB 9800 GT
TV tuner
DVD ROM
DVD RW
After assembly, everything POSTed, Windows loaded fine. I updated the SSD firmware to support TRIM. I ran Prime 95 for 16 hours with a max temp on core of 27 deg C (Ambient is 18), ran Memtest86+ for an hour or so with no errors, ran some other random tests like Passmark, and everything seemed kosher for a system running the X3, the 9800 GT, and the Corsair RAM at 1333 MHz (Stock for the Mobo)
So, of course, I tried updating the BIOS to 4.0, which was fine, then tried unlocking the 4th core. it POSTed, ran windows, and ran Prime95 on 4 threads for 16 hours with a max temp (not on core due to unlocking error) of 31 deg C. I decided to re-install Win7 Professional 64 bit, so I did and all was well. Ran Passmark and the benchmark looks similar, CPU-wise to other Phenom II x4 systems, so I think the 4th core is stable and working well.
Next step, I changed my RAM frequency from auto to manual and set it at 1600 MHz (did ratio to 1:4). All is well, though I don't see a major difference in Passmark. I then ran Memtest86+ and there were 8 errors after 8 minutes, all in a row. I stopped the test, and came on here. Memtest shows all correct data, including my CPU as Phenom II X4 20 (what the 720 looks like unlocked), the RAM at 800 MHz (1600 MHz)...but teh CAS is set at 9-11-11-29
Now, I'm a beginner, so I stopped there. I have a few questions:
1) is my RAM correctly set for frequency? If I plan on overclocking, should I keep it at 1333 so if.when I change the FSB, it has room to speed up? Should I change the CAS to 8-8-8-?? like I read a review on the XMS3 saying it was good to run at? Will that effect heat output? any ideas? Is Passmark a good indicator of performance?
2) For overclocking, my board has an "auto 20% overclock"...should I try that? if not or if yes, the current BIOS also has some auto-overclocking for the FSB...should I try that? there's no harm, right? if not, should I start with FSB, as per normal, or, since I have a black edition, should I go straight for the multiplier? What aboiut temperatures? are the temperature gauges on speedfan and HWMonitor correct enough to gauge CPU heat, what with the 4th core unlocked and a blank CPU heat gauge? Also, once I change something, is Prime95 a good enough test of stability and heat? Should PassMark be a good indicator of performance?
