    Poor Memory Write Speeds ( AIDA64 ) going form 3970x to 4960x

    Motherboard model: RIVE BE
    UEFI Version: 0701
    CPU: 4960x S0/S1
    Memory kit part number (s) and amount in GB: CMD16GX3M4A2400C9 16GB ( 4x4 )
    GPU: ASUS GF 780TI x 3
    SSD/HDDs/Optical drives: SAMSUNG 840Pro SSD RAID 0
    PSU:Corsair AX1200i
    USB Devices (model/version number):
    Monitor: SAMSUNG S27A950Dx3
    CPU Cooler:Corsair H100i with SP120 fans
    PC CASE: Corsair 600T
    Operating system: Microsoft Activated yes/no? Windows 8.1 / yes
    Drivers Installed (include version):
    Any third Party temp/voltage software installed: evga Precision X / MemtweakIT / Aida 64
    System Overclocked (provide details)? XMP / Synced 46 x ratio

    Issue
    I've noticed a change in my memory write values on the AIDA64 memory benchmark test since I got my 4960x and RIVE BE. On my 3970x and RIVE I have getting a substantially higher value and wondering what could possible be causing


    As a comparison
    i7-4960X Extreme HT 4600 MHz Asus Rampage IV Black Edition X79 Quad DDR3-2400 9-11-11-22 CR1 43759 MB/s
    i7-3970X Extreme HT 4600 MHz Asus Rampage IV Extreme X79 Quad DDR3-2400 9-11-11-22 CR1 71120MB/s

    Also noticed my latency is up on my ram from 48.3ns to about 53ns

    When I try and change my T_CWL_ADJ on Mem TweakIT, it just reverts back to 4 - i've seen on the interwebs that this could be causing the write speed issue ?

    Thanks for the help

    Similar experience upgrading from SB (3960x) to IB-E (4960x) @ same rated DDR3-1600 XMP RAM. I thought it was the transition from SB (which R4E is made for) to IB-E, but it's interesting that you're experiencing the same behavior from 4960x on R4BE which is allegedly made and optimized for IB-E, especially with respect to RAM!

    Where do I find this ? I can' see it under my tertiary timings in both Mem Tweakit and the UEFI ?

    tRDRD: Sets the delay between consecutive read requests to the same page. From a performance perspective, this setting is best kept at 4 clocks. Relax only if the memory is not stable or the system will not POST. Very few memory modules can handle a setting of 4 clocks at speeds above DDR3-2400 so you may need to relax accordingly, although the performance hit may negate any gains in frequency.

    The hasn't been a response about it yet since I started complaining about it 7-8 months ago.
    Board is pretty much useless without the fix.
