Will mixing 11-11-11 RAM with my 9-9-9-24 RAM slow my system?

[keithsterling]

I have 16GB of Crucial Ballistix 9-9-9-24 DDR3 1.35V RAM in my computer. I want to upgrade to 32GB, but Crucial no longer sells DDR3. They recommend 11-11-11 RAM but I am worried that it will slow the system down. I am not overclocking, but the BIOS indicates that it's using the 9-9-9-24 timing.

I use the system for Logic and Pro tools, music and post production audio.

There is some 1.35V 9-9-9-24 DDR3 RAM on Ebay, but it's ridiculously expensive right now. What would you do?

... Crucial no longer sells DDR3 ...

Hi there.

Is it just specific specialised items with that timing 9-9-9-24 you are looking for? Agreed only 11-11-11 seems to be listed. But at least it is available.

What are memory timings

If we think of memory as a race car, the module speed (MH/z) would be like the raw horse power of the engine, and the timings would be the driver of the car.

Edit: Apologies - misunderstood the question. Carry on ...

I think YMMV. From personal experience, when upgrading to 64 GB RAM, I tried to use a couple of new 16 GB sticks with a couple of my old sticks. "In the good ol' days" I thought you could match RAM as long as they were in the same bank. But no, with my motherboard, it wanted all identical sticks in each slot. So I ended up buying another 2 x 16 GB RAM.

When reading about it, they recommend matching all the RAM modules. It is best to get a pack of 4. If you go with unmatched RAM, they may or may not coexist peacefully with each other.

ok thanks for the reply tedyun. I'll purchase 4 new modules and re-purpose the old ones.

Personally I believe those 11 DDR3 RAMs should work with your system (Are they DDR3-1600 CL11?). If your old RAM is DDR3-1333 CL9 then the new RAM when installed should cause the system to run using CL11 including the old RAM, which may cause a slight slowdown. But you may not notice that.

But I agree that it is better if all 4 RAM modules are of the same type.

Thanks for the response Jamesbond007, I am opting for 4 new modules and I'll try to sell the old RAM on Ebay. Someone with an older system may want some old 9-9-9-24 Crucial Ballistix gamer memory.

I'm ok with the machine running a little bit slower, because it's high time to upgrade to a new machine for more complex Dolby Atmos mixing gigs (hopefully!)
