Seven 8 GB DDR3 Memory Kits For Your AMD A75 Motherboard

By Thomas Soderstrom

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.

G.Skill Ripjaws X DDR3-1600 CAS 8

While G.Skill is known for its high-end RAM, we’ve used its budget-oriented CAS 8 parts in our System Builder Marathon Series. Today we finally get to see how those same F3-12800CL8D-8GBXM modules stack up against the competition.

Our motherboard always boots at DDR3-1066, but at least it detects G.Skilll’s parts at a more performance-oriented CAS 7 setting.

CPU-Z is only able to display four readings, and it doesn’t show the DDR3-1066 timings (even if they are present). Instead, it starts at DDR3-1370 CAS 9. The memory’s rated DDR3-1600 CAS 8 timings are available on Intel motherboards as an XMP value, but our AMD-based test motherboard requires manual configuration to achieve the same performance level.

The better news is that no voltage increase is needed in order to utilize the rated settings, as stated on both G.Skill’s product page and the modules themselves.

G.Skill includes a lifetime warranty on all of 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.

    I bought the cheaper version G.SKill kit for $59 oh well :s can't wait for prices to drop again for a little splurge ;)

    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!
