    Good feedback guys! keep it coming

    Dual channel doesn't work on the board (or it says it doesn't)
    unGanged is just incorrectly detected as "Single" - if your DIMMs are in Slots 1&2 (closest to CPU) you are DualChannel.


    no DDR2-1066 or higher
    1066SPD equipped modules work fine, this is what Phenom Officially supports (I know the availability of such modules is not good yet, they are coming!)
    BIOS update is coming to allow 800SPD / 1066EPP (or just 1066 capable) modules run manually at 1066 memclk. So its a BIOS issue.
    ASUS & GBT already have EPP / manual 1066 modes working.

    tRC only at 26 max which will not let many RAM bootup
    In 1066 memclk mode the timing registers are encoded differently (eg. in 400-800MHz modes you have range from Trc 11-26, in 1066 mode its wider range 11-42 IIRC) - so once the 1066 manual settings are fixed in the BIOS you have more Trc options when you go to 1066 mode (same with other Timings).


    no control over CPU multi in BIOS
    There should be "custom PStates" menu for AM2+ CPUs in the MSI BIOS, there you can Adjust CPU FID, DID, VID and same for NB.
    these are not very user friendly to use, MSI is working on getting this part fixed.

    CPU FID=CPU multiplier, 00 = x8, 01 = x8.5, 02 = x9...

    NB FID = NB Multiplier, 00 = x5 (1GHz), 01 = x6 (1.2GHz), 02 = x7 (1.4GHz) ....

    DID = divider, can leave this to 1

    VID = Voltage ID 28 gives 1.25V VID value, lower value is higher voltage, higher value is lower voltage (00=1.55V) - note typically CPUs are locked to 1.25V or 1.30V VID value so trying to set higher than this might result in non-BOOT

    like I said this section is not user friendly! (just USE AOD to tweak this stuff!) - to be honest I dont remember if this section even worked in the latest MSI BIOS (need to check)

    HT multi changed in BIOS changes NB frequency and HT frequency
    This is because these are linked so that HT can not exceed NB frequency. So if you go to 2GHz HT your NB must run at 2GHz too. HT Can be lower than NB though.

    but OD and some other applicatiosn read very low core speeds (1.5GHz core speeds ~138x11).
    Which BIOS settings do you have to get this issue? Even at default?

    Also OD doesn't pick up core temperatures for me.
    Issue with AOD, its fixed now and the new version is out soon!

    OK....I have a relevant question macci, is the new AMD motherboards going to be like the Nvidia boards and Bios Updates will revolve around AMD or is it Dependant upon Board manufacture?

    source code is still being updated...some manufacturers are tweaking already though
    Got a problem with your OCZ product....?
    Have a look over here

    Thank you macci. Very appreciated feedback because MSI is not replying.

    Ah ok. Mine are 1066 EPP, so I can't run that and only get the option for 26 tRC max while the modules are known to do 1200 4-4-4-4 PL5 2.3V pretty easy stable.

    Thanks for that, greatly appreciated. You're right I had no clue as to what those were doing apart from setting mutli's because half the time I had no bootup if I changed them. Very good options though, will try them now.
    This is because these are linked so that HT can not exceed NB frequency. So if you go to 2GHz HT your NB must run at 2GHz too. HT Can be lower than NB though.
    That's what I found too. Can you tell me what the stock Phenom 9500 220HT ref. total HT speed should be?
    Which BIOS settings do you have to get this issue? Even at default?
    Everything on auto in BIOS.

    This is what OD and CPU-Z read stock everything right now: http://i222.photobucket.com/albums/d...__/NewBIOS.png

    CPU-Z validations fail if I change CPU/NB FID/DID in BIOS or at that. I can't validate even stock now.
    Issue with AOD, its fixed now and the new version is out soon!
    Very good to know. Looking forward to it!
