    Unhappy Ram 800 mhz instead of 1333mhz

    Before asking this question I've searched all around the forum but I haven't been able to find an answer. My hackintosh has:
    - Q8300 CPU
    - GT220 1gb DDR2 Video Card
    - 2x2GB DDR3 Kingston 1333 Mhz
    - MB P41T-ES3G

    The problem is that the RAM appears in System Profile working at 800MHZ instead of 1333MHZ and I can't solve this issue. Could anyone help me?
    Thank you.

    Are you sure that the motherboard, with Q8300 CPU, is running your RAM at 1333 Mhz, not 800 Mhz?

    Thank you. I'm sure, I checked that in the BIOS and in Win7. Any other idea?

    Not other idea, just that one. DDR3 =2x2GB? For DDR3?
    It doesn't make sense. How did it come up with 1333?
    busratio=?, bus speed=? cpu=? board ram speed?

    It should come out 800 Mhz class for RAM per Q8300 CPU family reportedly.

    But just my 2 cents.

    I still wonder why the ram speed comes up with a wrong speed. All the settings in Bios are ok, and my FSB works at 1333mhz. I'll run some tests using win7, to check my RAM's health because s.o. told me that kingston memories sometimes can't hold 1333 mhz speed . What a drag! It could be a hardware fail?. Thank you

    Edited: My RAM model is kvr1333d3n91.

    In case you're still wonder, there are OSX reported/display speed and actual running speed, and they could be easily different.

    As for DDR3, there would need to be a set of 3 sticks to make it works, not 2.

    The maximum board FSB and RAM speeds are different from the actual as per CPU/chipsets type.

    As for your Q8300 at 2.5 Ghz with a busratio/multiplier of 7.5 and bus speed of 333 Mhz (2.5G = 333x7.5), your RAM is not running at 1333 Mhz (its max capable speed may be).

    I have no doubt that your RAM is 1333 Mhz type though. As some of mine is 1600 but it runs at 800, already overclocked.

    Ok, now I know what you meant. Sorry, I had no idea. Now I know that I made a mistake buying that MB, there is no way to solve that. Thank you, great info

    You're welcome. The OSX display memory info, "about this Mac", is the class/type and it's routing to the closest "real mac models", as they don't have such thing as AMD or HP/Sony type.
    You could also check the real speed in hardware info tab.

    The other nice aspect of your CPU, that many looked forward to, is the ability to overclock without much trouble, as you can take it to 3.0 Ghz with just a bus speed changed to 400 Mhz. All needed is just a decent/cheap CPU fan (the stock Intel fan is not very good anyway).

    My Q8400 at 2.66 Ghz is easily clocked to 3.2 Ghz without much generated heat, and the overall performance is so much better (many people clock it all the way to 4.0 Ghz, but to me, that is a bit too much as I like the increased performance but would not like to "kill" it that quick nor rely on too extensive cooling solution). So far it's been very stable and fast though. I can run OSX and virtual win7 at the same time in the same desktop without sacrificed system performance.
    Oh, my overclocked CPU/system has its RAM at exactly 800 Mhz if you're curious.

    Thank you again. I'm going to o.c. my CPU to 3.0ghz , after buying a new and silent cooler. Do you recommend me a specific brand or device? Any good value? I feel that I'm taking advantadge of your kindness.

    It's OSX86 support and sharing.
    One of the reason people like about OSX86 is freedom to change any hardware, load any software/OS that suit their need/flavor.
    I think any fairly decent fan will do, as you would not oc it to the extreme. However, monitor CPU/board temperature just to make sure.
