    Swiss overclocker Christian Ney set a new memory OC record, clocking in at 1950.3 MHz (actual), 3900.6 MHz DDR. The record was made possible (apart from great skills), by G.Skill F3-2666C11-4GTXD 4GB DDR3-2666 MHz memory, AMD A8-3870K APU, Gigabyte A75-UD4H motherboard, and a liquid nitrogen pot made by K|ngp|n Cooling. A top performing memory module was picked from nearly a dozen modules. The 1950.3 MHz DRAM clock was supported by timings of 14-14-14-36. DRAM voltage is kept under the wraps. The CPUID and HWBOT validations can be found here, and here.

    That APU must have enjoyed all that memory bandwidth. I'm looking forward to the day when we have much faster RAM to make APUs with beefier graphics processors a reality.

    Pardon my ignorance, but besides apu's... what uses does super fast ram like this have?

    No. I still don't really get it. I know memory is the buffer to the cpu, so you are able to feed the cpu faster. 8 logical cores doesn't seem to need that extra speed much. The benchmark showed pretty minimal increases in most aspects. So high loaded cpu's could use a bit faster ram. I could see a 64 core server setup needing fast ram.

    Interesting not normal for AMD to take memory overclocking feats :eek:

    I have never overclocked my ram, and have only changed ram settings for stability issues when overclocking the CPU.

    I don't believe there are enough gains for me to spend that kind of time.

    Depends what you are doing. In an APU there are huge gains to be made. Even on a normal CPU depending on the game you can gain a FPS or so with some good ram. No one is saying go buy a $300 memory kit if you know how to shop you can get 2400-2800mhz ram out of a $50-60 kit.

    Memory bandwidth increase VS latency increase is what makes the real difference. I want to see the features of the DDR5, specifically link training and error correction implemented sooner in memory sticks.

    Remember that GDDR5 is totally different and not comparable with DRAM.

    I read reports that DDR4 standards have been approved and we can look forward to speeds from 2133MHz ~ 4600MHz.

    Yeah, I know that I've know about JEDEC finalizing the spec for DDR4. We won't start seeing it in the consumer market until at least this time next year. Better start saving for that rig. :p

    Yep, Intel announced no DDR4 support for Haswell, unless AMD decides to go for that.

    Server market, Haswell-EX might. Like I said though, we will be waiting a little while. :ohwell:

    Packing/unpacking... besides that... almost nothing else makes a palpable difference, especially on Intel SB/IB CPUs.


    DDR4's channel-per-DIMM slot thing... and it's sheer speed improvement to begin with, should solve most of what APUs need... also, if AMD implements some of that shared L4 memory Intel wants for Haswell's HD 5000 (?)... unified access to the memory controller should also speed things up. Either way, I love the direction AMD (& Co.) is taking with the APU thingy.
