Got an issue here with the system I just built. Well, not really an issue, but something that would make me feel much better if someone can help me out.
Here's what I got:
*** MSI NF750-G55 AM3 NVIDIA nForce 750a SLI HDMI ATX AMD Motherboard
*** G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL
*** AMD Phenom II X2 555 Black Edition Callisto 3.2GHz 2 x 512KB L2 Cache 6MB L3 Cache Socket AM3 80W Dual-Core Desktop Processor - C3 Revision
*** Cooler Master Hyper 212 Plus 120mm fan CPU Cooler
*** 2 x EVGA GeForce 9800 GT Akimbo 512MB DDR3 (SLI'd currently)
*** Cooler Master GX RS-650-ACAA-E3 Power supply - 650 Watt
*** Windows 7 Pro x64
My main question is related to unlocking extra cores which I successfully done, however I feel like the reason the system isn't as stable as it is being dual core because it has something to do with voltages.
In the BIOS I set everything to auto (everything that relates to CPU), logged on to windows, I see 4 cores and CPU-Z shows X55 quad core CPU. I did not run anything like Prime95 or any other utilities like that yet, however when I re-ran the windows system rating, at about 75% of completion when it comes to Encoding Windows Media or something like that, the whole system freezes and only reset button helps.
I've done a lot of research related to this CPU and tried to play with voltages vcore and nb but nothing changed. People say if you get to logon to windows with unlocked cores, then I guess I'm lucky, now all I gotta do is set it up, so this is why I'm here
It's fast enough being dual core, but I just wanted to be 100% sure if my processor is capable of being a stable quad core before I give up and leave it as a dual core. Most people get it to work but they all have gigabyte boards which makes the whole process much easier. As you can see, auto settings don't work in my case.
I'd really appreciate if someone can point me in right direction about getting the voltages and other settings to work and possible overclock a little bit.
Here's the screen shots being a dual core with green power and AMD cool'n'quite turned on:
The BIOS pics are just for your reference, I have no idea which ones I need to play with...
and now the Nvidia Core Calibration set to auto and everything else is on AUTO too...
No, thats why its easy with the unlocked multiplier, if you start messing with the bus speed you then have to look at Ht speeds and the effect on memory. I'd turn spread spectrum off and cool n quiet off if you are overclocking.
