Need suggestions for testing memory speed in Linux

Software & Operating Systems Linux
1

I recently put a new system together based on the A12 apu and I am going to start playing with memory overclocking as the memory speed has a huge impact on an APU performance. My problem is that memory over clocking on these CPUs are not that straight forward. In UEFI, it can only go up as high as 2400, so the actual overclocking should happen through playing with CAS and other underlying values, and I need to be able to benchmark these different configuration to be able to measure the effectiveness of them. I have searched on line and so far these are what I have found:

  • memtest(+) checks for integrity, not usedful in this context
  • dmidecode just report the values that UEFI is reporting and, due to what I explained above, is not that useful
  • RAMspeed ( from alasir ) is a candidate, but it needs to be compiled, so if anybody is aware of a howto guide for that please let me know.
  • STREAM is another candidate, but same as RAMspeed needs to be compiled and is even potentially more complicated as it needs openMP, so again, if you know of a guide, let me know
  • and last but not least, is using dd to read and write to tmpfs which probably would end up being the best way to go about this

So if you know of any other software or methodology that would accomplish this goal, or have any feed back on this topic, what so ever, please let me know.

Download this tarball, extract it, run ./build.sh, then you’ve got a binary ./ramsmp in the build directory.

Make sure you’ve got your build tools for your distro installed. (build-essential for Ubuntu/debian/mint)

Thanks @SgtAwesomesauce. My worry about building RAMspeed was mostly due to that fact that code was released almost 9 years ago and I was wondering if I have to update the build script in terms of compiler configuration to account for any changes or improvement in both gcc and/or cpu architectures. would it be fair to assume that you are saying that the build script, as it is, is still good enough?

I just tried it and it worked just fine. Not sure how accurate my results were though. I can’t imagine you’d need to change it. That’s the beauty of C. It doesn’t really change.

Thanks, that is good to know.

6

I just ran it myself and except for test 1 and 2, I am getting seg fault for all the other tests.

7

Oh, I don’t have that problem. :confused:

System specs: i7-2600k, 32GB 1600MHz, SSD

Output of all the tests:

for> echo "Running RAMSMP -b $i"
for> ./ramsmp -b $i
for> done

I have 18

12

I wonder why I don’t see all 18… :frowning: That’s odd.

MMX and SSE are the ones I’m missing.

13

the build script is using “uname -p” to detect arch which apparently is not consistent across platforms ( read distros). When I tried it on debian the arch is detected as ‘unknown’ and the scripts then build it for general case which doesn’t include SSE and MMX tests which are i386 and amd64 specific. On fedora, on the other hand, the arch is detected correctly which is why I got all the 18 tests.

But, while, on fedora, the compile goes through “correctly” it generates seg fault when it is run. On debian you can specify the correct arch by running the build as “./build.sh Linux amd64”, but then the linker generate the following error:

/usr/bin/ld: temp/intmark.o: relocation R_X86_64_PC32 against symbol `malloc@@GLIBC_2.2.5’ can not be used when making a shared object; recompile with -fPIC

I am looking into it, so far I’ve found this:

@SgtAwesomesauce I can also see the same options, 18 tests. In Fedora 26 FYI.
