i7 O/Cing with 6 memslots filled?

[FaaR]

I'm aware that it complicates matters, but I value plenty of RAM higher than mad CPU speed anyway so it doesn't matter.

What I wonder is, in what way can I expect to be limited by sticking in another set of 3 DIMMs? Right now I run OCZ Platinum 1600MHz memories at 7-7-7-20 1T timings and it's working great. Could I still run with these timings with 6 sticks, or would I have to dial it down a bit - and if so how much?

I am also a bit curious about CPU clocking on the i7, I have an ASUS Rampage2 Gene board, and the BIOS offers what it calls "CPU level up" and "Memory level up", where I can bump up CPU speed OR memory speed, but not both at the same time it seems.

Well, not without raising BCLK anyway, right? But that increases other clocks as well in the system, doesn't it? PCIe, SATA, and so on? Maybe USB as well for all I know.

I doubt many people here know the answer to your question, maybe hit up Rubycon by pm?

If you do find out the answer, let us know please. :thumbsup:

I am running 12GB with my i7 920 overclocked.

No issues to report.

Just make sure you don't get too aggressive on the RAM and you will be fine.

I haven't finished OC'ing yet, but it's looking like I have to drop a full speed-grade on the RAM to get it stable with 6 sticks.

How about command rate? (1T/2T)

I think I'm at 2T right now (my board also has an option for 3T). I ended up passing prime @4.2Ghz with the RAM somewhere near DDR3-1333 CAS8.

I have a 1250watt Enermax Galaxy PSU on it's way as my 750watt Silverstone was getting overloaded once the GPUs started working hard. I'll give things another go around once I am back home(had to leave town for a week on business the day after my new hardware arrived ) and get a chance to install it.
