I just got some new Patriot Vipers in a 2x4 arrangement for 8gbs.. before I had 1x4 for 4gbs. The new ram is interesting in that I couldn't get it to run at 850 MHz at 4,4,4,12 at any voltage while the old ram could do it at 2v. What else was interesting was that it could run faster than the old ram could doing 5,5,5,15 @1020 MHz. Is it typical of higher density ram to have a problem specifically with timings and not clock speed?

I believe its the extra strain on the nb running 8g. Did you up the nb voltage? I had to, to get 8g running on my board.

Timings do have an effect on ram oc's.

could be different chips (IC's) that the ram uses.some like tight timings others like loose timings and high speeds

That's exactly right - there are manufacturer responses on newegg reviews for some 4gb kits that explain that very thing. Wish I could remember the brand :confused:
