Some chips scale up to only around 1.55-1.6V, some scale up to 1.65V but most will scale well until around 1.58V according to results posted on XTremeSystems, any more voltage usually doesn't help with stability or worsens stability. It can depends on the IC's. These either come with PSC XDX028A3G-A or if you're lucky, Elpida J1108BBSE

memtest86+ results can differ from OS results; I do not use memtest to check stability of overclocked memory, as it is mainly for checking defective memory. You already proved it in this post.
I use SuperPi 32M and IntelBurnTest (high or very high depending on how much RAM you have [most likely very high] or even max, at least 20 passes; you can test with less passes in between settings changes). Prime95 works well too. I get break the 16 minute barrier in SuperPi 32M with my ECO's at 6-8-6 and IntelBurnTest is very fast too; I garner close to or over 80 GFLOPS.
I did not need to change any voltages/settings (even the IMC) when I added another 2x2GB. Just shows how strong the Phenom II x6 IMC's are
Try 6-8-6; 7-7-7 may not work because the tRCD (middle value) usually does not like lowering on PSC chips RAM. Most of the ECO has PSC chips.
: Be extremely careful, I heard before that someone killed their 1.5V G.Skill NQ with 1.8V; it has to do with the weaker IC's (Hynix or Samsung) in that generic 1333 9-9-9-24 RAM. This RAM has better PSC or Elpida IC's and as such can perform better, but due to the low voltage nature, past 1.65V they do not scale as well anymore; at 1.8V these kits would probably be DOA by then.Edited by xd_1771 - 11/19/10 at 3:58pm
