FX9370 Windows 7
 

I'm using Win7 on an FX9370 8 core.

I've got 32GB of 1866 DDR3 but windows says it can only use 16GB.

Is this a known limitation of windows7?

Win7 Home Basic 8GB
Win7 Home Premium 16GB
Win7 Pro 192GB

thanks

is windows 10 any better? the free upgrade I mean

Win10 Home 128GB
other Win10 2TB

(32 bit non-server Windows versions are generally capped at 4GB)

thanks

so I need to get the free upgrade to get the use out of my ram. Is upgrading easy?

Sure... Give up your privacy, and the world is your oyster....

Very easy, but if you have some other peripherals (as printer, etc) make sure first that you have a driver for it (check the CD, or the web page of the manufacturer). The "little one in the house" upgraded and she's happy with it, except she could not print and we had to spend some time fixing drivers issues. About privacy, is like Chris said, so better don't store "sensitive" things in the box... Your photos with the naked wife, or naked neighbor's wife may end somewhere in some cloud :smile:

Thanks guys.

Managed to upgrade.

I'm now getting ~60ms/iter for 2240K FFT's.

Before on 7 I was getting about 30ms/iter.

Might this be because I'm testing a larger exponent?

Does 60ms sound good for 4 workers on 8 cores with 4.4GHz processor?

You could run the benchmark included in Prime95 and compare your timings to the ones in the perpetual benchmark thread:

I am getting about 40 ms/it with a 3456K FFT, on an FX-8350 at stock 4.0 GHz, 32 GiB DDR3-1600, dual channel. This is with the one-worker-per-two-integer-one-FPU unit, or four workers on an 8 "core" CPU. The other three workers are running DC. There is definitely some memory bottle neck, though I haven't taken the time to test it, lately.

I suspect that something is holding you back, unless I misunderstand the work you are doing. The FFT given above is for a 65.2M exponent.

I'm testing 4 * 42 million exponents.
What could be slowing the machine down?

[QUOTE]Does 60ms sound good for 4 workers on 8 cores with 4.4GHz processor? [/QUOTE]I originally posted the response below to another, wrong, thread. I still don't know what might be hurting your performance. However, with a relatively new OS, driver problems immediately come to mind. Are you fully up to date with Windows Update and any main board drivers?

Misplaced response follows:
[QUOTE]If I understand correctly, you have arrived at the same setup which I have for my FX-8350. I treat each integer pair, with the associated FPU, as a "core". It has been a while since I set it up this way, and I may not still have the test results which got me here.

I think that I saw that a single integer unit, plus FPU, with the other integer unit not running P95, got better total results than running P95 with different LL assignments on the two integer units. Results were similar with LL on one integer "core" and P-1 on the other of the pair.

I now run 4 worker windows, with LL/DC assignments on the odd numbered cores, and the even numbered cores as helper threads. My rationale is that in this way each FPU, with the associated caches, are only doing one job, with two integer units, thus avoiding conflict over resources. Results were similar when I was running P-1 with the same allocation scheme, with the exception that Stage 2 only used ~1-2/3 'cores' once all the RAM was allocated.

I have been curious whether running 2 worker windows with 4 integer "cores" and 2 FPUs might perform any better through reducing memory contention, but some experiments made me think that this assignment scheme would not utilize the integer units fully. I don't know any way to see how hard a shared FPU is working. :smile:[/QUOTE]
