What's your memory assessment speed? [2]

Hum I am running 8GB G Skill @ 1866MHz and this my readout just surfing - my WEI is by the way 7.3 after installing a real basic NVidia GTX 650.

So is this good average or what as I have no idea what the performance is in relation to the run time.

Yeah, pretty good. What is that, double channel?

Quad channel @ 1600MHz with CPU OCed to 4.6GHz I'm getting about 37GB/s.

Run time is how long it took to run the test (additional factors involved here), not as much just how fast the RAM is. Memory performance is the number you want to know what your memory performance results were.

RAM speed can be so fast that the number of channels and the CPU can be the bottleneck, not just the RAM itself.

Double Wrend I was planning on 16GB and belting it up to 2133MHz but it (mobo I think) doesn't like that speed even with the two sticks.

Yeah, solid speed then for double channel. :) I think your CPU memory bandwidth maxes out at a theoretical 25.6 GB/s anyway (if I'm looking up the right one here).

What machine is that on again?

Please see "my system specs" bottom left of my post.

I did, that's why I asked

Exactly, what do you want to know?

I want to know if that RAM is in triple or quad channel mode. Under optimum conditions, with the highest binned parts, RAM in dual channel mode won't hit 38k MB/s. I think the absolute highest I've seen is about 32k, and for that test, the difference in 32k and 38k is a whole lot, not in the margin of error of hardware. I want to peek behind the curtain and see what the trick is.

My RAM is in Dual channel mode. There's only 2 (two) sticks. There's no trick.
All my BIOS settings are at default.
I haven't O/C yet as I'm waiting for Cooler Parts.

There is definitely something unusual going on though. 38GB/s is rediculous for dual channel RAM. Just saying.

The specs on your CPU even list the "max memory bandwidth" at 25.6GB/s. Nothing against you, but you'll understand why we're looking at this rather sceptically. There might even be something weird going on with how the test is run.

I would think you should be maybe getting around 28.5GB/s with your 2133MHz RAM, if the "max memory bandwidth" is based on 1600MHz.

All I can say is.

BELIEVE!!

:)

BTW all tests were done in Power saving mode, including my WEI
Whether that makes a difference I don't care. :)
