Benchmark RAM?

THX1138 · posted: 2017-10-09 17:49

My BIOS has a RAM setting which includes 'Turbo' and 'Ultra'. Ultra is not usable and gives long beeps during POST but I'd like to see what effect Turbo has, if any. What would be the easiest way to test this? The results for"benchmark" in SPM seem unrelated to this application. Thanks.

debian package mbw
tiny 25kb utility +dependencies (mysql-client) ~= 3.4Mb
after installling, read `man mbw`
"MBW determines the copy memory bandwidth available to userspace programs.
Its simplistic approach models that of real applications.
It is not tuned to extremes and it is not aware of hardware architecture, just like your average software package.

.
.

debian package sysbench
tiny 150Kb utility ~~ after installing, refer to its manpage
tool for evaluating OS parameters that are important for a system running a database under intensive load.
The idea of this benchmark suite is to quickly get an impression about system performance
without setting up complex database benchmarks or even without installing a database at all.
Current features allow to test the following system parameters:

file I/O performance
scheduler performance
memory allocation and transfer speed
POSIX threads implementation performance
database server performance (OLTP benchmark)

Thanks. Sysbench didn't work and I was told to use a more up-to-date version than what Synaptic Package Manager gave me but mbw program worked:

This is the stock result:

This is the result with SDP set to Turbo and Command Rate changed from T2 to T1. It actually looks marginally worse for the MCBLOCK method but may something was going on in the background.
