Haswell System Agent voltage

[teppic]

I want to push my memory slightly harder, and I see in the BIOS that the system agent voltage is useful for this.

What kind of adjustment is a good idea? It defaults to no change.

As things stand, oddly when I run memtest86+, the first pass is successful, but it always gives an error on the second pass.

whats it set to atm? I think you can manually set +0.025v from sins guide I read

no idea on haswell though tbh,i need to own/use it to offer any help

It just defaults to 0v change so I'm not sure.

However, I just tested at +0.05v and the memory completed two passes.

I'm running Patriot 2133MHz rated at 11 11 11 30 3T at 10 11 11 30 1T 1.65v.

edit: I'm going to try a couple of runs at +0.025v to see if it still passes.
