Super PI question

post #1 of 10
Thread Starter 
I am trying to tighten my ram timings, and using Super PI mod 1.5 to test it. I noticed the 64K line is always "Not calculated". This happens if my Ecos are stock at 9-9-9-24 or 6-8-6-15 or anywhere in between.

Is this a known glitch in the program or is this a failure? The program actaully finishes running with a PI calculation done along with a checksum.

32M is what you should be testing in SuperPi if you are testing memory. You may have an issue that is not in the memory (i.e. IMC, CPU speed) or the program itself.

I did more testing this morning, and this is what I came up with. I set the bios back to fail safe options, and I am still seeing it. This test was done with 1M. It doesn't matter what I pick over 64K, it always fails.









I also now have 3 different versions / installs of the program, and they all have the same symptoms. The result is the same each time I run each version. These are all based on 1M Calculations.

Supper-PI-mod1.5-XS (From web)


Supper-PI-mod1.5-XS (From OCN)


I also noticed I get the same results if I run these three against my laptop. I also found atleast one other person is getting the same results as I am. http://www.overclock.net/downloads/1...uper-pi-3.html (Post #26)

At this point I can only assume it is just a buggy application. What other common applications are used to bench memory?

If your 1090T isn't running Cool'n'Quiet, you appear to be underclocking it. Are the ECO's you have rated 1333 9-9-9 stock (as opposed to 1600 7-8-7 like mine?); any 1333 9-9-9 RAM can't be guaranteed to overclock far. I believe the G.Skill ECO 7-8-7 and 8-8-8 use similar IC's, but all the other ECO's use IC's that really aren't as good. One OCN member had a golden kit with great results but that's about it.

Yes it was running cool-n-quiet when I did the testing this morning due to the bois being defaulted to get rid of any OC configuration I had done. I wanted to make sure the results were not related to some change I had made.

They are the 1600 cas 7 ones. http://www.newegg.com/Product/Produc...82E16820231321

I have the oc settings back in the machine now, and am getting ready to run another test.

Edit:
32M test results on OC settings.
64K - Not Calculated
2M - Not Calculated
4M - Not Calculated
8M - Not Calculated
32M 17m 02.036s

What other program can I use to test with?

Ah, I see. I don't think 64k is an important one anyway, it's 1M (performance) and 32M (stability) you should really be paying attention to. I think it's a program issue. Standard CPU stress tests (Prime95 on Blend, IntelBurn very high/max) are good for testing RAM as well.

Just an issue with the app.
If it makes you feel better, keep track in notepad.

For a stability check on a multi core machine you'd be better running HiperPI.. This was developed to stress all cores together by running SuperPI on each one.
