Seven 8 GB DDR3 Memory Kits For Your AMD A75 Motherboard

Because integrated GPUs generally employ shared system memory, RAM performance has a significant effect on gaming frame rates. We're testing seven 8 GB DDR3 kits that manufacturers tell us are a perfect match for AMD’s mainstream Llano-based APUs.

    Where's the CAS7 DDR3-1333? Many of us are still trying to pin down how important timing are in the scheme of things …

    They're not.


    You're better off buying value RAM with decent timings and throwing that extra $$$ into a GPU. I promise your FPS will improve more that way.

    CAS 7? Most of the modules were tested at DDR3-1333 CAS 6.

    I have been looking at those Corsair kits for an upgrade and it's good to know they are approved.

    As has been known for quite some time, there is virtually no performance gain on DDR3 RAM with lower CAS because DDR3 has plenty of bandwidth and frequency. The higher the frequency the lower the cycle time in real time, thus CAS 7 vs. CAS 9 is totally insignificant in system performance.

    Is it a valid conclusion that, if the 8GB kits are good, then the corresponding 4GB and 2GB kits would be good to? Or will pricing make a difference there?

    Wish I found that Corsair CAS8 kit, but I did find the CAS9 version for $50, no rebate or shipping.

    Nice review guys!

    I got the HyperX modules the A8 and the Vengeance are on my main rig. Now, I'm still intrigued about unganged when using a 4 module MoBo. I got the A8 with 4 modules in unganged at 1600 CL9 and it runs pretty well, but i wonder how that compares to this 2 modules MoBo.

    Cheers!
