RAM leftovers

I woke last night with an idea. It may be a good one and it may be a bad one and your ever present thoughts would be appreciated.

As written elsewhere in this forum, my ancient I7 2700K is running well really. Last year and just before the sim was released, I upgraded the GPU and doubled the ram from 8 to 16. Now, I have that old Corsair ram upstairs and wonder if it is possible or advisable to put this into the system to give me 24GB of RAM.

Any ideas or comments? Many thanks.

if it has the same timing yes, else no no.
different brands of ram can give issues.

Does the RAm run at the same speed, if so give it a go. I did the same as you before I did a major upgrade. I had a 3770k and bought additional ram (corsair vengence ddr3) and put it in motherboard to increase ram from 8gb to 24gb

My old Pc ran for a long time like yours would with 24gb. I set the ram speeds and timings for all sticks to the slowest ram module xmp profile specification. My PC was 100% stable, but depending on how old your modules are and what kind of modules you have, I would not necessarily expect higher game performance. If you need more ram for other tasks, it could be worth it. For just gaming probably not. The next Sim Update is supposed to reduce the required RAM aswell.

This is good. Keep it coming! It isnt a critical thing for me as I am dribbling over the spec for a new machine when prices come down a bit, but is just that I remembered that I have my old 8GB Corsair kit in a drawer and if it looked like a no cost improvement, then I for one, am up for it. I do have other stuff running on the system, such as a Streamdeck, plus varied software which might have a little more room to breathe with the extra. It is a very good point though about the upcoming update and the likely reduced RAM usage.

If the old ram is slower then the new ram, the new ram will in effect run at the slower speed of the old ram. Brands mean nothing (other then quality perhaps) if it fits in the slot is should run. I mix ram all the time and have never had any issues with it except of course for the issue I mention above.

We mix ram all the time at work and have several hundred PCS we maintain for our users.

Some info:

  • the stories about mixing brands and timings are not entirely myth they were absolutely true with DDR2 which was very fussy but mixing ram is unlikely to cause big issues with DDR3 or DDR4 unless you are overclocking
  • this is particularly true of Intel motherboards which really do not care about ram types and timings the same way AMD processors do
  • do not mix and match if you are overclocking
  • if you do mix timings ALL your ram will run at the speed of the slowest stick
  • if you mismatch ram capacity in the same bank your ram will not interleave this will cost you maybe 5% or 10% in ram performance (not system performance just ram performance) as well
  • hence if you have the cash buying new matched sets of identical ram is still the optimal option
  • however if you do not have the cash the overall performance benefit of extra ram in a game like MSFS can easily out weigh the loss in performance from mismatched ram - just test it and see

i said can…it doesnt need to give issues, maybe try not to interpret too much, ty

there ty, now thats a good explanation.
