    Thank you so much.

    When the Memory Frequency was set to 1600, the CPU core temp was 48c. I mentioned that at the top of my post with the bios settings information.

    The system booted up straight away at 1600, without any reboots, or any issues. In fact (and I know this will sound crazy), the system feels "less" stable at 800Mhz. At 800Mhz, I get some pinwheels (like hourglass) when opening some things, or clicking on some things. When set to 160Mhz, I never got these instability symptoms - and yes, all with 8gb of RAM installed.

    Is that crazy?


    Best,

    And you never had the red warning when entered M.I.T?
    Gigabyte suppoert DDR-1333, but there is only one qualified module for that and it's 1GB and qualified with 1 DIMM in each slot only for total of 2GB.
    You can burn a bootbale CD of Memtest86+ and run it. It will probably report actual RAM rate, besides testing the memory.

    I'm sorry I neglected to reply to your inquiry regarding the red warning in M.I.T - I have seen that a couple of times when booting to the bios, yet I don't recall exactly what the message said. I can try to duplicate this again if it is of interest?

    I think I will try to run Memtest86+ from a USB drive, as I have not been successful when trying to do so from a burned CD.




    Peace my friend,

    The burnt ISO won't boot?
    If you can make a bootable DOS USB flash drive you can run ramspeed benchmark from it as well.

    To get temps down on OS X you need to fix processor power management. Before that was much harder and required a lot of DSDT editing but now it is handled by Chameleon if you use a prerelease version of rc5. You will find a thread about under New releases and updates.

    Chike: I was able to make the ISO image burn correctly and am running Memtest86+ (ver.3.4) now.

    mm67: In terms of "fixing" processor power management, what may I ask shall I do? Is 48c to hot for a system like this? I am running Chameleon rc5. (may I ask if you have much experience getting other video cards to work in OSX? I ask not for this system (nVidia 8800 GTS 512) but for another system I'd like to build with an ATI HD4650 card I already have, another Gigabyte Motherboard and i7 processor)



    Again, my thanks for your continued help. In my experience on the web, assistance like this is extremely rare, and getting rare-er. I don't know exactly why everyone has allowed me to ask as many questions as I have, or why you've simply decided to assist me, but I can tell you that I have never been so impressed with a community of experts in my life. I just hope I can become 1/2 as educated about this stuff as you all are, so I may in turn assist others.

    Genuine thanks,

    I don't about your cooling and ambient temperature but to me that 48 C looks pretty high, mu cpu won't idle with so high temps even when running at 4.25 GHz. If I drop speed to same 3.4 GHz that you seem to be using I get temps like this:
    Attachment 2851

    CPU A-D are core temps and Cpu heatsink temp is the same you were looking at in bios, Northbridge is the same as bios System temperature. That's my temps at 3.4 GHz, ambient about 23 C at the moment. If you are running Chameleon rc5 then you also need to use GeneratePStates and GenerateCStates options in com.apple.Boot.plist. That should fix power management so you have exactly same temps in OS X and Windows.

    I never tried to use Ati graphics with my systems so I really can't help with that, you should find plenty of help from InsanelyMac forums.

    Chike:

    Memtest86+: I ran this overnight and the results this AM are:

    Pass complete, no errors, press Esc to exit.

    I trust this is desirable?

    mm67:

    In terms of editing the com.apple.boot.plist - is it just a matter of adding a key and string line with "GeneratePStates and GenerateCStates" in them? Or do you mean something different? Would you have an example of what to do with those two things perhaps? I would very much appreciate it sir.

    I am a member at InsanelyMac as well.

    Thank you once again my friend,

    This is my complete com.apple.Boot.plist file:
    Attachment 2852

    And these are the lines that enable speedstepping and C-states:
    <key>DropSSDT</key>
    <string>Yes</string>
    <key>GeneratePStates</key>
    <string>Yes</string>
    <key>GenerateCStates</key>
    <string>Yes</string>

    Forgive my ignorance; so it should look like this:

    (somewhere on my com.apple.boot.plist)

    <key>DropSSDT</key>
    <string>Yes</string>
    <key>GeneratePStates</key>
    <string>Yes</string>
    <key>GenerateCStates</key>
    <string>Yes</string>


    .....And then i just need to repair permissions, or do i need to do something in terminal to allow these things?


    Thank you so much mm67.
