How much power?

So my 4GB of OCZ OCZ3G10664GK are giving me a nice pile of errors. (10+ after 30 seconds of memtest86+)

To fix this, they suggest putting the VTT at 1.35V (up from 1.135V).
I currently have the RAM at 1.6V.

Will this kill my processor? It's a Core i3-530 on a Biostar T5XE (with a Foxconn retention bracket).

Any ideas? Or is the RAM simply bad (again)?

The max CPU VTT for the Core i3 500 and Core i5 600 series is 1.4V. It should be safe, although it could possibly be bad RAM. The reviews from newegg on those sticks aren't particularly good - seems like OCZ has some QC issues with those sticks.

Do you have a link to this information? I know that the Lynnfield CPUs spec state a max of 1.155V and an absolute max (thank you Intel) of 1.210V but I haven't seen the Clarkdale specs. I wouldn't mind giving the Clarkdale specs a read.

A post from OCZ- a suggestion for someone with the same motherboard and RAM.
I've set all other settings as such, but I'm just a little leery of adjusting the voltage.

I see no reason why you should raise your cpu voltage to make your ram stable.

Have you tested the ram with memtest86?

If it's not stable, I'd get different ram.

The memory controller is on the CPU. The Vtt is the Voltage for this MCH. Asus refers to the Vtt voltage setting as IMC or Integrated Memory Controller. So sometimes this V does have to be raised to stabilize your RAM. However if you set your DRAM V to 1.64, your Vtt to 1.15 and your memory multiplier to 8 and you still get errors, I'd return the RAM.

Here, from overclockers.com, which was part of an Intel spec datasheet which I couldn't find on Intel's site, but then again my searching skills suck. :kaola:

Thanks Lmeow, I found it here: http://download.intel.com/design/processor/datashts/322...

Looks like the max is still 1.155 but the "absolute max" is 1.40V (as you showed). I wonder if that's a result of the architecture change. On Lynnfield, it's on-die. On Clarkdale, it's still on the CPU but not integrated on-die. "Remember the memory controller that Nehalem so graciously integrated? Clarkdale kicks it off die again. The IMC is housed in the 45nm GMA die. It’s still on-package, but not on-die." http://www.anandtech.com/show/2901
