Windows 7: What's your memory assessment speed?

x2 3GB DDR3 @ 1067 MHz. Shouldn't it be a little faster than 6GB a second?

Has anyone seen this on winsat mem?
Specs for this system in the CPU-Z snips. this is my secondary system and IBT won't run, it stops with an error saying to use admin privileges, which I did to no avail.

Forget what I posted Gary.. That is why I deleted it.

Googled it and I found a couple of similar issues but no explanations.

Thanks Mike, I read it but came more confused. I've fooled with the HT and NB frequencies and it still shows the RDTSC crap and IBT still won't run. Just odd.

Quote:
The RDTSC instruction has, until recently, been an excellent high-resolution, low-overhead way of getting CPU timing information. With the advent of multi-core/hyperthreaded CPUs, systems with multiple CPUs, and "hibernating" operating systems, RDTSC often no longer provides reliable results. The issue has two components: rate of tick and whether all cores (processors) have identical values in their time-keeping registers. There is no longer any promise that the timestamp counters of multiple CPUs on a single motherboard will be synchronized. So, you can no longer get reliable timestamp values unless you lock your program to using a single CPU. Even then, the CPU speed may change due to power-saving measures taken by the OS or BIOS, or the system may be hibernated and later resumed (resetting the time stamp counter).

I might be understanding this wrong but... Basically both RDTSC and QPC are used to time code in time-sensitive programs. However, RDTSC might be inaccurate in above described situations. I also might be wrong about this but I believe QPC has something to do with the HPET high precision event timer. Which is a more accurate timer.

So this might explain why RDTSC and QPC has a delta that is too high. And if all of what I said above is true, then this error is benign.
Googling does find people with that error, but usually not accompanied by any performance issues. A Guy

Thanks Bill.

Now I'm only 99.9999% confused.

Thanks Bill, I did read that too and it's true I haven't noted any lower performance.
I think Mike cursed me a few months ago when he commented my machine is "quirky"

I'll go with 100% for myself.

Maybe it is just that the operator is quackers.

Your system should have DDR2 RAM, download CPUZ and check the Memory tab.

This score is normal for DDR2 RAM.

You can also check the CPUZ SPD tab for each motherboard slot to see what RAM cards are installed. There are no 3GB RAM cards, Gateway has either put 4GB and 2GB or 3X2GB cards.
These are not optimal but do work.

Attachment 218151
Interesting attachment.

Will it run Prime95?

Does the RAM pass memtest86+?

Your NB frequency looks good.

Have you bumped the IMC voltage?
Might need to bump the DRAM voltage a little also.

Just a thought, you might try loosening the RAM timings and set the command Rate to 2T, see if it passes then.

Memory Assessment Speed
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 ?
