Windows 7: What's your memory assessment speed? [2]

Well Paul, those are some expensive LEDs. Wasn't long ago 2133 RAM was expensive, at least they offered financing for it.

How about $400 per 4GB?

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?

Try .05V increments and loosen timings to 10-10-10-32. I wouldn't try voltage more than 1.6V though myself.
Did you mean GSkill F3-12800CL9-4GBRL?
Your CPU memory controller may not be able to run 1600 RAM faster that 1866 though.

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.

If it is only showing in the bios and not in Windows then it could be that the overclock is failing before Windows starts. How are your checking the speed in Windows? Most of us use CPUz.

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.

This is the score of my 1600 MHz bumped to 1800

Just a curious question; I ran winsat mem a couple of weeks ago and got a 13600+ read. Ran it today and got 15985 read. Only system change was adding a Radeon 6670 Video card. Does memory speed change this much ? What might cause the disparity ?
