How can I overclock the ram to get it upto or close to the 1600mhz ? it's set right now @ 1066. it is 1.65v ram.
What is bclk? and how does the memory multiplier work ? and what about uncore ?
And would I leave Turbo on or turn it off ? and the multiplier would I leave it at 20x?
Best practices for OCing an i7 920 would be to Turn off Speedstep, Turn off Turbo, and set the CPU ratio to 20. Some people will say turn off Hyperthreading, but its a GOOD performance feature and I wouldn't want to disable it. You will get a higher clock, but you loose the hyperthreading ability.
I would start by setting the vcore to 1.2v which is stock and seeing if it will boot with a BLK or 190 (190x20 = 3800MHz) If it does not, bump up the voltage to 1.25. If that runs stable and after stress tests, you can try 1.225v if that is not stable, stick with 1.25. If 1.25 is not stable bump up to 1.26185V or whatever it is.
Personally I also set my Memory to use the XMP profiles. This set my vDRAM to 1.6, I believe stock is 1.5 and "max" for an i7 is 1.65 (per intel specs). I set my QPI to 1.2v which is stock as well.
Just watch your temps using coretemp or something like that. I use OCCT 3.0.1 with custom settings as follows for an hour: Large dataset, High priority, Hyperthreading ON.
BETTER TIMING!!!! SHUT UP!. haha sorry. 7-7-7-24 is great timing. I have 8-8-8-21 timing and I was able to change from 2T to 1T timing, but that was about it. I start playing with the rest and it fails. I'd start by getting your CPU OC stable before worrying about your memory.
I've read some of the comments posted on Newegg with this memeory and how some people can not get the 7-7-7 timing to work. OCZ's response was it does have issues with some memory at this timing. 8-8-8-24 would probably work and seems to be fine with alot of 1600 modules.
