Ragemem results

Postby Roland » Mon Dec 04, 2017 10:33 pm

I would be interested to know what kind of Ragemem results other X5000 users have obtained... It can be also run from SysMon.

Is it normal that the memory test gives significantly lower results for X5000 than for X1000? And that the results are somewhat different depending on whether there is only one or two DIMMs installed in the machine?

If there are e.g. two 2GB or 4GB DIMMs installed, does AmigaOS use both of them, 50%/50% or 25%/25% (within the limits of the currently possible maximum)?

My experience is that AmigaOS does not care if I install two DIMMs, although it can only use one of them. That is not the same result that U-Boot shows: on my machine, U-Boot slows to a crawl if I install 2x2 GB DIMMs and won't run at all if I install 2x4 GB DIMMs. Although U-Boot crawls with 2x2 GB DIMMs, once AmigaOS has booted, it runs just fine, so it is a U-Boot problem.

Some Linux users report that RageMem and some other benchmarks show disappointing results on an X-5000, compared to an X-1000. The reason is unknown, but the result is clearly nonsense, as any real test you care to try using OS4 (memory copy speed, read/write speed, I/O speed etc) performs about 20% faster on an X-5000 than on an X-1000, as you would expect.

If you install 2 DIMMs, U-Boot will initialise them to run interleaved, so they will naturally be shared.

Sounds strange... Is your U-Boot version the same as in standard retail machines? What brand of memory have you tested? I have two 4 GB Kingston HyperX 1866 MHz DIMMs (HX318C10FWK2/8) in my machine, and have not noticed any slow down with U-Boot. They are classed as CL10, but U-Boot System info reports CL8 for them. So far I have seen only CL9 in other X5000s.

Is there any other memory test program than Ragemem, which would make more sense...?

"Ragemem" "It can be run from Sysinfo which is included in the 4.1FE." ?

Really ? Maybe you meant that the Crisot RageMem can be run from SysMon included in zTools AmiStore package ?

Thanks, I corrected the name! I may have mixed it with Ranger for which there is a version included in OS4.1....The SysMon version I have is 4.3 (2013), I suppose it must be from OS4Depot originally. There are so many programs and versions around that it is impossoble to remember all details...:-/
