Memory question

post #1 of 15
Thread Starter 
Would there be any benefit to me upgrading my memory from 1866 to 2133? I have seen some things here that the memory speed effects the tpf and I'm trying to get mine as low as possible without frying my cpu, lol.

This question is relevant to my interests. However, I would garner that upgrading from 4GB to 8GB would be a more significant gain, if you're folding bigadv, than going from 1866 to 2133.

Not unless you run very specific software that could make use of it. It makes infinitessimal differences (especially on SB) for what is a relatively big cost.

Read this and this

edit: just noticed this is in folding section (facepalm) but I'm 99% certain it makes no difference at that speed.

Memory does in fact have an effect on folding, especially big/huge adv work units.

-4GB total memory is sufficient, more will not help you.
-Higher speed memory, and tighter latency's will both improve your TPF.

Before pointing to test like that you should make sure they include folding@home. F@H is not a game it is a very memory intensive software and memory speed and timings make a rather significant diffrence even on sandys. The bigger the WU the bigger the difference but if you wand to gain a minute or 2 on bigadv frame times then memory is a very good place to do it.

I would upgrade seeing that 2133 Ram is pretty cheap (55)

+1 Grandpa knows of what he speaks. Memory matters and can really help frame times, this applies for frequency or timings. 4GB is currently enough, but who knows what the future brings.

I have noticed that i dont use all of the available ram, but if i were to move up to the 2133 i would probably get 8 gigs just to be safe.

It depends on your OS and setup as well. I am running Win 7 while folding in a linux VM. My RAM usage fluctuates between 5 and 6.5GB folding like this.
