Most of today’s modules only required 1.50 V to operate at their rated settings, but a few were designated 1.65 V designs. Without a proven track record for over-volting the memory controller of AMD’s 32 nm Llano APU, we decided to play it safe at 1.60 V. One of the 1.65 V-rated kits still took first place, as Mushkin’s Redline 997000 reached incredibly low 8-9-5-15 timings at a high DDR3-1866 data rate.

We never thought ASRock’s minimum tRAS of 5 would be a restrictive factor in our memory tests, but AMD’s new memory controller and the high-quality ICs used on today’s top modules combine to facilitate surprising low-latency capabilities.

Mushkin also wins the overclocking competition, though the top six of seven kits finished so close together than we have to wonder how much of today’s results are due to luck, and how much is due to custom binning by memory manufacturers.

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

    Cool Review !! I liked it ! this review enforced my decision to choose Adata Ram-.

    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!
