Hello folks;
I have a question about the importance of RAM-speed for math-intensive applications like eg. Folding@Home.
We tend to think that faster RAM will always bring better performance. But is it really so simple?
If you have a 16-core cpu, I suppose it is.
But I have 2 much smaller CPUs laying around here: An Athlon 200GE (2-core, 4-thread) and an older AMD A8-9600 (4-core).
I would like to let them work for science and run Folding@home, or any other science app running on the BOINC client.
I still need to buy RAM and motherboards for those 2 CPUs.
The Athlon officially supports DDR4 2667, and the A8 supports DDR4 2400.
I know that there are faster DDR4 RAM modules like DDR4-3200.
But so:
If I buy DDR4-3200, will these chips be able to run this RAM at that speed, or will they just throttle it back to 2667 or 2400Mhz?
And will Folding@Home or other math-intensive software even get any profit from faster RAM? (with these Athlon and A8 cpus)
If the answer is no to even 1 of those 2 questions, then I don't need to bother and just buy cheaper DDR4 2400/2667Mhz modules.
I was thinking about buying 2 cheap A320 mobos for these CPUs too.
If anyone of you thinks that I would better invest in a B350 or B450 mobo for some reason, please let me know.
Thanks in advance for your advice.
Have a nice day;
Carl
