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?
