Getting RAM from 1600MHz to 1866Mhz

Aderes Devorah · 18 Oct 2012 at 02:14

Hi all

I am trying to get my GeIL RAM up to its full speed (1866MHz) or maybe slightly higher and cannot get it over 1600MHz.

I got to 1600MHz via the bios, turning the multiplier to x8.

The mobo is the GIGABYTE 880GM-UD2H. Their Web site says:

"(Note 2) To reach DDR3 1800MHz or above, you must install two memory modules and install them in the DDR3_3 and DDR3_4 memory sockets."

My two memory sticks are indeed in sockets 3 and 4.

So, how do I get higher than what I have achieved so far?

Is it to do with the timings?

Any help would be wonderful as this has been bothering me for a couple of weeks now.

Best

Have you tried loading the XMP profile?

Had a quick Look at the specs you need to overclock the FSB to reach the rated memory speed.

Will his AMD motherboard support Intel XMP?

think XMP is only for Intel

After updating Bios on my ASRock Fatyl1ty Pro 990FX last night it was able to read XMP, this was not noted in the changelog, but a new option was available in bios under Ram Timings.

And yes its an AMD Board with a Bulldozer

since you have no xmp, it means you need to enter timings manually as well as speed. try entering them, see what happens?

Overclocking ram is pointless really.

mostly agree, ram speed isn't a big deal most of the time. but it's worth trying to get what you paid for; op is definitely justified. since you would expect ram to work at rated speeds, you wouldn't even need to test the "overclocked" speeds.

edit: didn't see OliverDavis' post... op maybe you want to try flashing bios. xmp should hopefully work

if that doesn't work you could try a tiny voltage bump or changing command rate to 2t, though at this stage i would fully agree with Leeroy123 and say the "overclock" isn't worth it.
