sisoft sandra 2010 processor arithmetic benchmark

because of crashing problems and no real information to explain why i decided to get sisoft sandra.

when i do a benchmark on processor arithmetic it always freezes up my computer as in the mouse wont move and cant do nothing. this is the same thing that happens with other programs but it is more intermittent there.

i ran the test several times with the same freezing happening all the time. i run other tests and none of them do this but some tests just seem to go on forever as if they are stuck in a loop. maybe its the program i dont know.

before the freeze my 1st core goes to 100% then seconds later freeze and i have to reset the computer.

i ran prime95 before i got ssisoft sandra and it ran no problems which seemed to me it wasnt doing a thorough enough test. the computer isnt overheating, i have auto fan control and when it gets to ovet 50c the fan goes on max and i can tell by the sound and it only did that on prime95

Normally, Sandra's benchmarks DO freeze the mouse and keyboard for a while. The progress meter will eventually update to a higher percentage, and then it will freeze again. It does this until it's finished the test.

The reason for this is that the results are more accurate if the CPU isn't wasting cycles on extra stuff like the mouse, etc. Sandra minimizes the CPU time of everything it can, so that it can concentrate on the test.

My quad core can take up to 5 minutes to run some of the tests, esp. the memory ones. How long is your machine locking up on you?

it locks up pretty much straight away and because only the first core was upto 100% surely the other cores would allow it to work on mouse movement. when i used prime95 the cpu load was 100% for all cores and i could still move the mouse without problems i will retry the test now for 10 minutes and see what happens

you were right i let the program create a full report then i looked at it took some time as it was very long the only problem i can see is this:

Cannot use Large Memory Pages due to lack of privileges.

this appears on memory and processor elements that were tested

Glad it worked. The memory page thing is pretty normal. I'm not sure it's an error. It's mostly just a flag telling you that it couldn't use large pages. I've never figured out whether there's a big difference or not so I've never bothered to enable it.

i found this page Lock pages in memory? so i followed what it said to do and i did see a difference in the results however im still getting the warning.

there is a warning on the properties of this policy but i think that would only apply if you had a little amount of ram where as i have 4gb installed.

ive attached pictures of before and after to show the difference its not a hige difference but it is an improvement im just wondering if there is something else i can do as this error still appears.

The differences are actually pretty minor. I remember looking this up a while ago, and there was a reason that I didn't enable it. Might have been a compatibility issue with something, I can't remember now. It might be worth doing a little research about enabled vs disabled. Maybe some of the other guys here know more about that one.

Edit: I guess it would have helped if I had noticed the link in your post. IIRC, lock memory pages benefits a server more than a desktop.

i did a bit of googling and this warning came up a lot and from what ive found my memory efficiency is a lot higher than most peoples systems so im happy that its not a problem. trouble is now i still have my crashing system i still have to resolve.

Is your RAM voltage at spec? Corsair's spec, not the auto setting on the motherboard. That might do it.

im not sure what to do there ill find a link to the ram then you can tell me if you know lol
