Can't get stable settings on Phenom II x3 720 Black, Gigabyte MB

post #1 of 8
Thread Starter 
This was my first computer build, done a year ago, and even though I've read guides and tried to understand how to set the bios, I haven't been able to figure it out so that it would pass stability tests (Prime95, OCCT, AMD Overdrive). I've lived with the hangs and other glitches, but I just found this site and maybe someone here can tell me what I need to do to get it right. Then I could think about actually over-clocking.

The temperatures seem okay. It is at stock settings as far as I can tell. The RAM passes MemTest86+, so it probably isn't that. Might be wrong bios settings, defective motherboard or CPU. Let me know what information I should post. Thank you.

What kind of OC are you trying to achieve?

Are you adjusting voltages?

First I am trying to find stock settings that will pass stress tests. The only settings I am adjusting are DDR3 Voltage Control (I think it is called DRAM Voltage Control in the Gigabyte bios) in a range between 1.85V - 1.95V, and CPU NB VID Control between 1.25V - 1.35V. So far nothing I have tried has passed.

OHH NO!

Lower you ram voltage to 1.5v-1.65v

It is possible to have to much voltage!

From Mushkin for my RAM with my Gigabyte motherboard: "DDR3 Voltage Control: +0.25V - +0.35V (1.85V - 1.95V)
If experiencing instability increase CPU NB VID Control: +0.1V - +0.2V"

These are my current settings in the Gigabyte bios:

System Voltage Control - Manual
Dram Voltage Control - 1.90V
NB Voltage Control - Normal 1.100V
NB PCIE Voltage Control - Normal 1.800V
CPU NB Vid Control - +0.100V
CPU Voltage Control - Normal
Normal CPU VCore - 1.3250V

Uhm, StuffStuff...
That RAM has Samsung HCF0 ICs
He could push 1.8-1.9V and be safe on it
But what he SHOULD be doing is running better than 1333Mhz CL9 at that voltage, now that is just beyond beyond unacceptable. The RAM is rated 1600 7-7-7-20, and with a small bump in voltage could probably even do 6-6-6.

Jdec spedifies that all ram must run at 1.95v with out pernament damage, donsnt have to be stabile tho.

how ever the heat could kill it

I put it at 1333MHz when I was putting everything back at minimal settings in the hope of getting through a stress test. I will put the RAM back at 1600MHz and maybe change the multiplier and see if that helps.

I guess I could take the computer to a shop and let them figure it out. But if I can, I'd like to do it, if just to understand how it works.
