Hello guys and girls.
POST EDIT: Decided to start a new thread for this issue and deleted my post from the other thread.
Any way, the 2x2GB OCZ Platinum Edition DDR3 1800MHz has arrived and I've installed it in the P.C. however the GA-X48T-DQ6 MB is registering the DIMMs automatically at 1333MHz (or 3:5 FSB😀RAM) at 7-7-7-20 timings.
I have tried to manually set it to 1:1 FSB😀RAM multiplier (my CPU is at 400MHz x 8 stock) with auto timing in BIOS and it freezes or willl not POST or doesn't boot into Windows.
It's convenient that BIOS automatically resets to factory defaults if there is a problem with any settings in BIOS.
The VDIMM (or DDR15V as it is called in BIOS) is set to auto in BIOS and is shown as 1.728V which is well below the 1.9V recommended by OCZ. I figure that increasing the voltage (or DDR3 overvoltage stated in BIOS) by 0.15V or 0.2V (it has to be a N x +0.05V increment) should solve this problem, then I can manually sort out the timings. Am I on the right track here?
The only really weird thing is that Gigabyte uses a strange FSB😀RAM multiplier system, where I think the correct multiplier for 1:2 FSB😀RAM is 4.00D for running the DIMMS at 1600MHz. Please can you confirm if I'm right because although BIOS states that it is 1600MHz for 400MHz FSB, CPU-Z states that the DRAM frequency is 800MHz. I don't know which one to believe. Either that or I am interpreting one of them incorrectly.
Thanks for reading this and any members who have the same MB or RAM as me may be able to shed some light on the situation.
Any help is greatly appreciated.
