    DDR4 speed for new Summit Ridge

    saamoison

      I read some were it was 2400 or 19200 GHz.  anyone know for sure?

          Until AMD officially releases Summit Ridge CPUs and / or the specifications the general public won't know for sure. Since current FX-9000 series CPUs support DDR3 at 2400 MHz. it is likely that Summit Ridge CPUs will fully support the JDEC DD4-2400 MHz. frequency ( Max 19200 MB/s transfer rate), DRAM. It's possible that motherboards will offer faster DDR4 frequency options which Summit Ridge may be able to use without issue similar to DDR3 DRAM operation. It remains to be seen if there is any tangible performance gains with DDR4 DRAM at higher frequencies as DDR3 running at 1600 MHz. isn't a current single CPU desktop system bottleneck which is why higher frequency DRAM shows little or no tangible system performance increase contrary to the DRAM benches which assume the DRAM is saturated 100% of the time which it isn't.

          One point of significance on DDR4 DRAM is that you need to buy the full quantity of DRAM that you desire in one purchase as it is not possible to add more DDR4 RAM like is possible with DDR3 DRAM. If you desire additional DDR4 DRAM in the future you would remove the current DDR4 in your PC and install the newly purchased DDR4 because DDR4 uses a different topology than DDR3 and prior DDR DRAM.

              Hi  I kept  looking and found out that will use DDR4 @ 3200 (25600)was the latest number.  AMD should go up with it's memory speed.to help with through_put.
