Less Dimms the better? (X99)

post #1 of 7
Thread Starter 
My mobo can use up to 8 Dimms/64gb ddr4

So it can technically do
32gb x2
16gb x4
8gb x8



Let's pretend all 3 cost the same, would the dual 32gb Dimms give the best performance? (Let's say they're all 3000 cas 15)

I think the less dimms you have the better, but since you have an x99 I think it would be better to make use of the quad channel so go 16gb x4.

Darn I don't think avexir has 16gb Dimms. Wanted to replace my corsair lpx with some avexir blitz 1.1 ram.



Any other ram companys with leds?

I heard corsair is coming out with LED memory, other then that I do not know, but I also do not think quad channel makes that much of a difference so...

I'll think about it, might just do the 8 Dimms. I really don't need 64gb tho lol. The 32gb 2133 ram I have is good enough just trying to make the aesthetics of my build nicer

Yeah man, I know that tongue.gif I am considering myself to buy another 16gb of LP 3200 for my build tongue.gif aesthetically I do prefer a full memory bank tongue.gif

running 'full bank' with all slots full = faster for memory intensive applications, even vs. using the same amount of RAM in half the slots (assuming all channels still active).

 

Pro's of full bank:

 

*faster vs same quantity in less slots

 

Con's of full bank:

*harder on IMC - less chance of high frequency

*harder to get more RAM that is binned to the same degree (having one oddball stick etc)

*greater chance of failure with more RAM

 

 

 Its cheaper to buy 4x8 sticks than it will be to purchase 8x4 sticks in the long run, as the odds are not in your favor of getting that many sticks with close enough or identical bins/XMP settings; its hard to tune and wont get anywhere near the speed potential of running less physical sticks, regardless of quantity of memory. Its also easier to upgrade when all your slots arent full already... vs having to go through the whole process again to find suitable pairs for full bank  setup.

 

ie- of my own, I have a 4x2 set of PSC.. all sticks individually or in pairs will do 2200mhz, 8-11-7-26 1T . Yet when all 4 are run together on the same setup/CPU, the best I am able to achieve with stable results is 2200mhz, 9-10-9-26-2T. There is a big difference in the amount of bandwidth the memory controller is handling when running full bank vs. not. This is the main reason why latency cannot be pushed as 'hard'.

 

Hope that helps you some.
