Gigabyte EX58-UD5/Extreme Discussion Thread

[Simfan]

I would rather have the 12bg of RAM. I really value long term reliability, so I am not keen of going nuts with volts either. 12GB of RAM at DDR3 1600 is running fine right now. Would the integrated memory controller be a plus or hindrance in this case?

Ive got the same 12Gb of memory as you.

This works or me on F5g, F6b, F5 final:

Select xmp profile as this automatically sets the correct memory and qpi/Vtt volts (1.65/1.35). The memory will actually run at lower volts than this if required. Memory will run at 1688 10/10/10/26 automatically.

Set the memory multiplier to x8.

Set Bclk to 211 and multiplier to x19 gives 4 Ghz.
Set processor volts to 1.41875 in bios. They will be much lower in CPUZ. Only with a decent cooler.

Set Uncore manually to give 2x memory speed = 2x1688=x16.

Set LLC on.

Set IOH to 1.3v

Dont forget to set the PCIe to fixed value at 100.

Turn off HT.

Performance Enhance: Standard.

Turn off processor turbo mode.

I've typed the above from memory so may have missed something but if you have problems I will check my settings. This on the Extreme MB.

Memory bandwith 29G/bs according to Sisoft. Prime95 2 hours max 75C ish.
Much lower for games (60C).
