Real world benefit of going from 8Gig to 16Gig system RAM - gaming W1064bit

post #1 of 3
Thread Starter 
I have a question, I'm moving some system parts around between PCs and I've got an Intel i5-4460 @ 3.2 Ghz on a ASUS H97-PLUS mobo running W10 64bit using 1 stick of 8gig RAM. This is a backup PC and is used for basic gaming needs - WoW and Overwatch (really just the Blizzard lineup games and sometimes the Wticher3). Here's my question, is the bump up from 8 gigs to 16 gigs of RAM worth the cost? I mean, I know this is overclock.net and assume most builders would always say more is better, but what exactly would the bump give me? The system drive is a 256 gig SSD so I'm assuming the memory page swaps are fairly speedy whenever a game might need more RAM. The video card is an aging AMD 6950, but I'm going to be moving that to a GeForce 1060 with 6 gigs of VRAM, so assuming the GPU removes that bottleneck should I break out some $ and buy more RAM?

Short version: assuming 6gig RAM Nvidia 1060 on an i5 at stock with 1 stick of 8gig RAM - yes or no, worth the money to move up to 16 gigs of RAM for gaming?

If you are willing, could you (briefly) tell me why, or at least in layman's terms tell me what I'm getting from the additional RAM that I might not be getting now. Is it more a paper / spec upgrade or is this something I can see with my own eyes? A couple of posters in other forum threads (other sites) mentioned some games are CPU bound, so would more RAM benefit me here (in ways I don't see now).

Sorry - I'm not sure how else to phrase this, but anything you can add will help. I don't know the exact RAM stick that's in it now (it's downstairs and I'll have to get it later, but I think it's G.SKill DD3, 1 stick of 8gigs).

Anything you can tell me would be helpful, thanks!

Performance wise, you will see little difference unless your ram is full. When ram fills, old data or unused data is moved to the hard drive (a very slow process) or deleted and then new information is placed into ram. When the old data is stored on the hard drive and needed again, it grabs that data and moves it back to ram (another very slow process). This hard drive allocation is call swapping or paging.

Swapping can cause games to hickup. Dropping randomly to 0 fps then back up to full. With an SSD, those drops are shorter, but still there.

With new games, ram requirements have increased to around 8gb. So this swapping will be problem in the future if the computer doesn't have enough.

There can be some performance increases by changing from 1 stick of ram to 2. it effectively doubles the amount of data that can be moved in the same amount of time. you may have heard of 'dual channel' and 'quad channel' ram. this is the number of data paths that the cpu/mb can use to communicate with the ram. It requires that number of ram sticks to function or multiples of that number, if there is an odd number of ram, the computer defaults to 'single channel'.

So basically, you may see an fps increase by switching to 2 sticks of ram.

Edit: as a side note, with 16gb of ram, you can turn off the page file option and be ok. been doing that for years with great success. Makes the computer feel snappier when returning to background programs that would normally be swapped to the hard drive.
