DDR3 ram memory timings important ? also 4x2+8GB vs 4x4GB and RAM compatibility

Recommended Posts

Posted · Original PosterOP

Hello, i am looking to upgrade how much RAM i have in my PC.

+Is ram memory timings important for DDR3 ? cl9 vs cl11 for example 1600MHZ

 

+Would adding a 8gb stick with 4x2 instead of having 4x4 affect FPS ? maybe less impact than 4x2 vs 8 alone ?

 

+How do i figure out if RAM sticks are compatible with each other ? I have 2x4gb old kingston hyperx 10th anniversary edition 1600Mhz sticks, will adding one or two ADATA 1600Mhz sticks work out for example ? or maybe 2x4gb 1600Mhz Gskill Ripjaws ?

1. cl 9 will be ever so slightly faster than cl 11 probably

2. the memory will be running in dual channel. how this affects performance, i am not sure

3. If their timings, and speed along with other factors are close enough, they should be compatible. it is always best to have identical kits

Ryzen 9 3900X overclocked to 4.3-4.4 GHz

I currently have 16bg of Corsair Dominator DDR 3 in my system set in 4 x 4 x 4 x 4 configuration. Paired with I5 3570k. Not much of an upgrade path these days?

Thanks for answering.

1. Do you think a cl11 would affect the cl9's own performance even though it's in another single channel ?

2. So the one in the single channel will only affect its own performance i guess ?

3.What if their voltages are different ?

It's just that it's hard to find the used ram kit/sticks that is perfect for my needs in my country. I have not used this PC for three years.

I got 4x4gb of ddr3 g.skill 1600mHz cl9-9-9-24 for about 60$ CAD shipped on ebay like last year.  Been working like a charm since then and I suggest you find the same exact kit that you already have or go for all the same ram.  2x8gb or 4x4gb is probably the best way to do thing and I'm pertty sure that 2x4gb + 8gb will be suboptimal (just a feeling like that, I've never tested that).   If you go for different kit chances are that they juste won't work at all together (slim chances but can happen).  If they work they will use the lower frenquency and looser timing so you might loose some performance there if they decide to run 1333 cl11 or even worst.
