x58 triple channel & high speed 4 modules?

post #1 of 4
Thread Starter 
I was wondering how well would 4x2gb kit perform and overclock on x58 chipset triple channel with 4 memory modules? I'm thinking of higher freq ram like 2200mhz or more? How much does it depend on CPU's IMC, and...other factors? I really never tried this but looking at these new 4x2gb or 4x4gb kits makes me thinking?
Obviously 4x2gb should be less hassle? Let's say you have strong IMC on 980x?!

On 980X (water cooled), for 4 DIMMs (4 x 2GB) QPI/Vtt 1.4~1.5V & DRAM 1.65~1.7V, 8-9-8-24 1T. But depends on the DIMMs rated spec.

 

Newer DIMMs will require less voltage and/or if you raise the BCLK or Memory Multiplier or both. If you raise the memory multiplier will need less QPI/Vtt.

I was not sure on this one, I'm glad you mentioned this.
On strong water cooled 980x I would probably go with higher multi rather than raising BCLK followed by memory multiplier, I believe that would be best compromise and vise thing to do.
Second thing is that I'm not sure which ram would be good choice for that performance (high freq and if possible tighter timings). Team Xtreem and G.skill have some nice kits that could do over 2200Mhz biggrin.gif

Also I read somewhere that using 4 modules on triple channel actually has bad performance hit comparing to 3 or 6 modules, I'm hard to believe this is true?

Benchmarks maybe but, for 24/7 none.
