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.

Kingston HyperX Genesis DDR3-1600 CAS 9

The OEM business seems to be Kingston’s primary market. However, the company continues to maintain its aggressive HyperX product line to keep the attention of enthusiasts, many of whom end up in working as or for OEMs.

A firm best known for its conservative defaults, Kingston surprised us this time with a kit that was detected by our motherboard at CAS 6. That default configuration is matched only by Geil in today’s comparison, though none of the modules in this round-up are really meant to be used at low data rates and correspondingly low timings.

The memory’s rated DDR3-1600 CAS 9 settings are also available as a default, but only on motherboards equipped to use that SPD register. Ours was able to set these timings automatically after we chose a DDR3-1600 data rate manually. DDR3-1866 CAS 11 is also available semi-automatically, thanks to a corresponding DDR3-1954 SPD value.

Kingston provides a lifetime warranty on its DRAM 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!
