Seven 8 GB DDR3 Memory Kits For Your AMD A75 Motherboard

By Thomas Soderstrom
published

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.

Corsair Vengeance DDR3-1600 CAS 8

Normally known for performance, reliability, and compatibility (and not necessary the best pricing), Corsair surprised us by making its CMZ8GX3M2A1600C8R kit one of the least-expensive CAS 8 DDR3-1600 8 GB kits on the market.

The box photo shows us exactly what these modules look like, sporting cut aluminum heat spreaders creating fins that extend module height to 2.1 inches.

Our motherboard automatically set Corsair’s CMZ8GX3M2A1600C8R to DDR3-1066 CAS 8. Those slow timings are caused by corresponding SPD values that limit CAS 7 to a nonstandard DDR3-1036.

DDR3-1333 is also in the program, along with AMD-incompatible XMP settings for the memory’s rated performance. We configured this set manually for our benchmarks.

Corsair’s lifetime DRAM warranty is limited to the original purchaser of its products.

    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!
