Testing memory with Super Pi

[meloxicam]

I need some input on proper ways to test memory with Super PI.

I have read that in order to completely test you RAM you need to run multiple Super PI 32M executions from different directories until you use up all the available RAM. So for 1 gig you would need to run 3 or 4 32M tests all at the same time.

Is this true?

If this is not the case, how should I test? Please describe a proper method.

Thanks!!

Run 1 instance for single core and 1 or 2 for dual core. That wil do

I like memtest for windows for stability testing for ram:

Does this need to be done from 2 different directories?

I like memtest for windows for stability testing for ram:

Do I need to run one copy of this for each core, and if so, do I need to run it from 2 separate directories?

Thanks for the quick replies!

For dual core cpu create 2 folders both containing spi exe and start either 1 or both of them.

I used the one in dos for more precise testing. Perhaps it's the hardest test for true ram stability. It's very easy to get errors with anything over +500mhz and cas4. Yet you will pass Super Pi or even Orthos no problem. I have much respect to memtest over SPI/Orthos as far as memory is concern.

play a game, if it crashes its not stable

I tend to either do a few hours of dual 32M or loop 3D benches for a few hours if I'm really looking for maximum stability however I consider any rig WCG stable to be 100% stable.

Should memtest them in dos mode 1st (v1.65)

Otherwise you risk corrupting your OS with unstable ram. (especially after a few BSODs)

Place exe's in two different directories as it was allready told. Then run both of them. And in Windows Task Manager, in the Process Tab, right click in each Super PI and choose Affinity to define each exe to each core... Then start both Super PI at same time...

If you want to test memory you should use memtest86+ 1.7. It will test your entire memory modules. Win memtest will only test a portion of it.

I think some of you that are overclocking should take system stability a little more serious. People who tell you to play a game to see if it crashes as a way to see if your system is stable are not very knowledgeable.

I've had orthos running perfectly fine for one day then the next day when I turn my computer on orthos would fail. I later found that my memory was to blame. I had to loosen up the sub timing to get my memory stable. Memtest gave a couple of errors everytime I ran it but I decided to ignore it since orthos was stable. I was wrong to do so. None of my games were crashing when memtest gave the errors. This could be all in my head but I notice that my computer is running much smoother now with my system memtest86 + orthos stable.

I suggest you run memtest86+ first to test memory stability then test with orthos for cpu stability. Run both test for at least 3 hours. Do a whole day if you want just to be sure.

Win memtest will check all of your RAM. If you have more than 1Gb and try to check all availiable RAM, you should run 2 winmemtest and the program will split total memory in 2 so that each instance can test half total availiable memory.

lol. That's how I usually do it when i'm lazy.

I like memtest for windows, but I also use spi. Memtest in dos doesn't seem as good. I can be stable in memtest and not even be able to boot into windows. If you really want to test your system, run some d/c apps 24/7. Join the WCG team and see. (Shameless plug)

Maybe it's your cpu and not your memory?

Yes, maybe T07N is right. memtes in DOS checks your ram. if its out of erros and you still cant boot to Windows maybe the cpu needs more vcore or even NB.
