CL9 and CL11?

[Jh4nTy]

Hey guys. I currently have 2x4gb running in dual channel and I want to put another two sticks of ram with 4gb each, making a total of 4x4gb.

My current RAM is CL11 and the ones I saw are CL9, everything else is the same (DDR3, 1600mhz, 1.5V, etc.).

So my doubt is if I will experience any problems by having 2 CL11 in dual channel and another CL9 also in dual channel. My MoBo is a ASUS H81-Gamer.

Thank you!

The faster CL9 DIMMs will be made to run at the slower CL11 DIMM's timings.

Meaning exactly?

According to ASUS you should always install dimms with the same cas latency. Check it out on page 1-8 of the manual

According to anyone who knows anything about memory you should always use matched sets and never mix in different channels

All RAM will be forced to operate at the slowest RAM's memory speed and memory timings.

If I were to buy this new set there would be 2 sets. I wouldn't move the channels. My current ones would still be in the same place and I would simply add the other two to the other channels. By colors: 1 set on the Gray and another on the Black. Not like 1 part of a set on a black channel and another on a gray. I hope I made that clear, my english isn't the best.

I just want to know if I can actually use the other two I was planning to buy (https://www.amazon.com/G-Skill-F3-12800CL9D-8GBXL-PC3-12800-RipjawsX-9-9-9-24/dp/B004I763AW/ref=sr_1_1?ie=UTF8&qid=1495046625&sr=8-1&keywords=gskill+ripjaws+x+series+8gb) or not and what the best solution would be for me.

i would not mix them also did you check your motherboard compatibility list they might not work there also have 8 x2 gig set in the list so you could get one of them and sell the old one .

Thinbg is, it would be a lot cheaper to get 2x4 than 2x8... what if I buy 2 new sticks exactly like the ones I have?

 

[scout_03]

if they are same model and number should work .

They won't be running at 1600 MHz.

* Due to Intel® chipset limitation, H81-GAMER can only support single-side memories when four modules are installed and they will run at the maximum transfer rate of DDR3 1066 MHz.

So, the best option would be to get 2x8gb?

2 of these should do the trick right? https://www.amazon.de/G-Skill-Ripjaws-X-Arbeitspeicher-240-polig-DDR3-RAM/dp/B00634BCD6/ref=sr_1_4?s=computers&ie=UTF8&qid=1495050281&sr=1-4&keywords=ripjaws+ddr3+1600

Yes. The G.Skill Ripjaws-X F3-12800CL10S-8GBXL are on the ASUS H81-GAMER Memory Qualified Vendors List (QVL).
