Small fft wont show instability as quickly as blend.

The other day I passed 2 hours small FFT on 5.0ghz and failed blend in 4 minutes.

Do blend for 12 hours. If you use a lot of RAM in your typical use (like lots of tabs open), then run it Custom with 90% available RAM, dont change anything else.

8 hours is not really enough IMO.

Since I do initial testing with OCCT, I use Prime Blend only, 6-10 hours.

The problem is "Blend" will only use about ~2GB of your RAM, and you have 4GB. That's why I recommend doing "custom" instead. From there you can specify how much RAM to use - in this case try about 3400MB.

No need to run small FFTs as well, they're ran under the Custom test so long as you don't change any other parameters (just RAM usage.)

That said - you're probably just fine.

thanks man. but do you think im good and stable?

i'll try your advice and add more hours if i dont feel lazy. hehe.

Go check out the sandy stable club in my sig.
Read the first page carefully and you'll know what to do.

Also this is what I do.
Run HCIMemtest to see all my ram is fine.
Run LinX or IBT with AVX (win7 sp1 required) to see how high my OC can go.
Run Prime95 custom blend with 90% of free ram to be tested on ffts 1344 & 1792 and run 2x15min cycles.
Run Prime95 custom blend with 90% of free ram to be tested for 12+ hours.

If I pass all this, I can finally say it's stable.

Keep in mind if you arent the type of person to have a billion programs running at once while playing a game, you might not have any use for heavy RAM testing. I still do it anyway though.

It's up to you to decide. What I say matters the most is whether the computer works for you or it doesn't. Set it to what you think should be stable (even if you feel 1 hour is enough), then use your computer and see if it crashes.

If you are doing very important work or require near-100% certainty that the calculations are right, you should test for 24 hours Prime blend. Otherwise, I'm not sure, it just depends what you want.

I'm having an issue with memory usage on Prime95 v26.6 Version3, when I do blend or CustomBlend, it never seems to top 1600MB used memory, even if I try to type in another value, such as 14400 (i have 16GB installed)

What am I doing wrong?

Does it only get used more in later tests?

Found the issue, administrator rights issue. Darn Win7 hand holding.

Just a quick question.

If I ran a blend test for 9 hour and nothing happen. How do I know it's stable and that I can push higher ?

no error = stable or we have to looks at logs to know ?

No errors equals stable. The longer you run the test the better. How ever any thing over 24 is imo over kill. I usually consider my system stable if it clears 12h blend.
