What's your memory assessment speed? [2]

On a related note, I have my G Skill RipjawZ F3-12800CL9-4GBZL RAM happily running at 1866 MHz with no other changes in the BIOS except the RAM speed itself.

When I try increasing the speed, all that happens is that the BIOS sets RAM to that speed (eg 2133), but when in Windows, AIDA64, CPU-Z etc show that the RAM is still at 1866 MHz.

Do I need to increase voltage or change timings? If so how and by how much?

Just got back from a 2-day trip to a wedding.

Will definitely start on the RAM voltage thing in the next couple of days.

The RAM in question is this:

G.Skill RipjawsZ F3-12800CL9Q-16GBZL 16GB Kit (4x4GB) which AIDA64 identifies as I have written it above.

The motherboard itself is supposed to be capable of upwards of 3000MHz RAM speeds (OC'ed).

I don't think you'll ever get 1600 to run at 3000. 2666 may be able to be clocked up to 3000, again dependent on the CPU.

Heh,

I have no intention of ever even trying for 3000 with this RAM.

All this is just an experiment. I am now running happily at 1866 and intend to stay there till I upgrade to some faster RAM later this year.

However, I am finding that even if I do make changes in the BIOS, those changes show only in the BIOS - ie, there is no actual change to the RAM speed or timings.

I wonder why that is.

I use CPU-Z, which shows the RAM running at 933.3 MHz (~1866MHz).

I am able to get the RAM up to 1866 MHz, but not more than that.

Probably asking too much of it.

I will stay at 1866 for now, and do an actual upgrade some time later this year.
