8 gig CL8 need voltage change?

[Redemption77]

I was just wondering if along with changing my timing, would I need to change voltage settings on my motherboard or is just changing the timings enough. If there any other system setting I should adjust, feel free to let me know. I dont think I am getting the performance i should be.
Thanks:

You should set it to what is on the memory.

So the voltage is the same for 8 gigs as it is for 4 gigs?

[GSKILL TECH]

Yes, but you may need to raise CPU-NB Voltage.

Ok. How do I find out how to do that?

[GSKILL TECH]

In BIOS, look for that option in the voltage section. Raise it to 1.20V and see how that works.

I did as you said and I definately see an increase in gaming performance on games like Crysis 2 and Batman AA. I thank you. I do have a question though. why 1.2 v? will this damage my memory controller? It seems stable now, but is this considered overclocking?

[Redemption77]

Come to think of it, I dont even know what the original values were set to. It just said auto. I think I should post some screen shots of my BIOS so you can see.

Generally AMD CPUs should be able to support full slots of DDR3-1333. Sometimes with DDR3-1600, we have to raise this voltage to stabilize the memory controller since AMD does not natively support it. But apparently with your specific CPU, it is lacking and having a problem even at DDR3-1333, so it may be a weak one. You should probably contact AMD before warranty expires to get a new one, but let's see how it holds up.

Default is 1.10 or 1.150V for your CPU. 1.20V is a slight bump so it won't damage the memory controller at all. If you say it is stable, it is actually better for it.

This is not considered overclocking, your memory is still DDR3-1333, but raising this particular voltage is one step in overclocking so you are getting some experience.

What model is your memory anyway? haha

Nice thanks! My memory is F3-10666CL8D-4GBRM
