Which memory to get?

post #1 of 7
Thread Starter 
I'm looking to upgrade my ram but i'm not sure what to use

The options i have is to either get

[*]a kit of 8gb 1866 of unknown brand
[*]or get another kit 8gb of hyperx 1600 (i already 8gb of them)

the reason i'm asking is becuase i've heard that the 8120 runs better with the 1866 then the 1600 is this right?
Any pointers is welcome

Neither. Get a kit of Samsung 30nm, OCs great even at >2000MHz w/ low voltages. thumb.gif

But the cpu and motherboard only supports 1866 officially i'm really clueless when it comes to ram so will 2000 even work?

depends, if you want to add RAM to your existing RAM then its always safe to go with the same that you have so your guaranteed to maintain stability.. tho mixing can work if such things a voltages and timings are the same..

anyway, i would recommend these Samsung too if you want a new kit. though in my books 1600 RAM with nice timings is really all you need in the real world unless you want to bench.... smile.gif

You are probably better off getting more HyperX's or equivalent rated RAM (at least).1866 or higher with 4x4GB is difficult on FX, and 1866 is only officially supported with two sticks. The Samsungs are nice though.

I wonder how they figure 29.9GB/s tongue.gif

It depends on what your goal is. If you need more than 8 GB. for some reason then you can add to your existing RAM or buy one matched 16 GB. RAM kit, as mixing of DDR3 RAM is not always sucessful.

The default FX RAM frequency is 1866 MHz. but independent testing by Tom's Hardware, AnandTech, X-Bit Labs and OCN member "damric" show no significant gains in real applications on typical desktop AMD or Intel PCs with RAM frequencies above ~1333 MHz. excluding Llano APUs where the GPU section benefits from the higher RAM frequency. The reason there are no significant gains is because DDR3 @ ~1333 MHz. is not a system bottleneck as older, slower DDR and DDR2 RAM was. See the link for details if interested.

http://www.overclock.net/t/1237178/is-o-cing-my-ram-worth-the-trouble/10#post_16866022

If you plan to add 8 GB. more RAM instead of purchasing one matched 16 GB. RAM kit, then the best chance of getting the two RAM kits to function without issues is by buying the same exact model RAM. As Corsair and others have advised, mixing of DIMMs or RAM kits even of the same part number does NOT guarantee that the mixed RAM will function at the Advertised frequency and latencies of a SINGLE DIMM or RAM Kit. So you may be forced to loosen the latencies to make the two RAM kits function without issue at 1600 MHz. Only testing can determine this.
