Skybuck’s CUDA RAM (Speed) Test version 0.10 is now available at the following link:

Some improvements have been made to the test program, it looks a bit more professional to me
The test program now uses 123 MB of host ram and device ram, so this should make it possible to run it on practically any graphics card with compute 2.0 or so.
The test program now also pauses after it’s done, so it’s easy to see the results and make a screenshot of it or copy & paste the text.
(if command line parameters are specified like --noprompt it will simply terminate as soon as it’s done, this allows profiling with visual profiler).
The ammount of blocks has been reduced from 20.000 to just 4.000 so the program doesn’t take so long to run.
Some additional interesting information is displayed about the device, about the settings, and about the calculated optimal dimensions and kernel launch parameters/dimensions.
A screenshot of what to expect is included as well:
And here is the output in text form (new/fresh run):
Test Cuda Random Memory Access Performance.
version 0.10 created on 21 july 2011 by Skybuck Flying.
Device.Name: GeForce GT 520
Kernel execution time in seconds: 3.4775507812500000
CPU execution time in seconds : 1.4399700939644564
Cuda memory transactions per second: 92018785.6710395765000000
CPU memory transactions per second : 222226837.4470134930000000
I hope you will give it a try and run it and then post some results here… that would be interesting !
If anybody wants to discuss the kernel used by the test program, and this is the place to do that ! =D
