Twin2x2048 - 6400c4 Pro

question I have a P5N32 E-SLI and I am using corsair TWIN2X2048 - 6400C4 PRO and want to get 1066 speeds. Can anyone give me the recommended settings to run this memory at 1066 speeds. I was able to hit that mark with SPD speeds but I believe I can get it faster with the right tweaks.

Right now I am able to get 4-4-4-12 @1T timings with this ram. When I initially purchased this Ram I was able tohit 1066 but at stock speeds only the voltage was upped.

 

I think I cann hit 1066 but at faster speeds buit I just need to know if anyonw was able to do it with the same setup.

You would need to be using our Twin2x2048-8500C5 modules for 1066.

 

 

Really, weird, I can actually get 1066 but i have to set my speeds to spd and only adjust my voltage on my memory. I guess I am one of the lucky ones..

Thats not uncommon to be able to over clock our modules, just if you want to run at 1066 you should be using a module rated at that speed. You do know the max supported Voltage for these modules would be 2.1 Volts correct?

Yes, I went to the website homepage and checked the specs...thanks

Ramguy,

 

Question I have been looking all over the web and this forum in particular and I cant find the actual numbers or should I say SPD for the advanced timings under this memory. Are there posted SPD numbers for the advanced timings, instead of just the basic settings.

 

I hope this makes sense..LOL

Weird, i know what the basic timings i was just inquring about the advanced timings trc,twrt,trfc etc. I didnt see anything on the web. Does corsair have it listed or is the timings for advanced settings dependent on the motherboard. The reason why im asking is because I see people stating that they changed trc to 24 and trfc to 42 and some have posted twrt at 15.

 

I just want to know what the default numbers are to these settings. By having the base numbers it will give me an idea of where I'm at if i decided to increase the numbers but if thse numbers are based the board then I will have to find something posted on other sites if it isnt here..

 

I hope I make sense..

 

:)
