What are your thoughts on using intel burn test?

Is it a good test to run and would you say it is better/worse than prime95?

Good catch.  It looks to me like you may need to lower the amount just a little bit.  Try lowering it a little, like try 15,000 MB.  According to a calculator, 15,000 MB is exactly 91.552734375% of your memory (out of 16,384 MB).  You can also compare your temps between something like 15,000 MB and perhaps 10,000 MB.  If the temps are higher when using 10,000 MB, then try values slightly lower than 15,000 MB until the temps match a much lower amount (such as my random example of 10,000 MB).

 

Edit:  Intel Burn Test isn't as stressful as Prime95 v27.7 build 2 because Intel Burn Test does not use the AVX instruction set which means even though IBT makes the temps a bit higher, it's not stressing the entire CPU like Prime95 v27.7 build 2 can.  However, only Windows 7 SP1 (and Windows 8 of course) provide 'access' to the AVX instruction set.

lol i put in 14gb and it still says 99% frown.gif

when everything is idle though my memory use is like 5-10% so i think this may/may not be normal. i'll just wait for a crash lol

ALSO I invested in some home made foaming for my case, and I bought "silent" fans... Can't hear my fans at 100%!

ok i g2g i have lsat class. i will let this run and i told my dad if it crashes just kill the power lol

It is normal for some of the memory to always be filled while Windows is running because Windows itself is in memory, but then so are other things that are needed.  The only thing that should be at 0% when idling is the CPU usage.

 

Anyway, can you try 10 GB and see if that results in 100%?

He won't have to kill the power if it crashes because if it crashes, then it'll just be idling.

No, because now you know it's not stable which means the result will be that you increase your system's stability.  Once your system can run Prime95's custom blend test using about 90% of your memory for well over 12 hours, you will know that it's rock-solid stable.  Until then, it's just a game of continually increasing your system's stability, so every time it fails, it's a road sign saying that you still have a little way to go yet.

I would say that it's likely, but it's never a guarantee.  :)

Anyway, I don't know anything about this degradation stuff.  As far as I know, the overclock you have now is very safe (relatively, of course, as always).

140% is fine, although I don't know what this setting is for.  I used to think that I understood, but I'm using 100% for 4.7 GHz with my 2500K and it's fine.  I may do some research to learn more about it because I've been in the dark about this for over a year now.

Finally, I think 4.5 GHz is a good overclock for the 3770K.  Now, if this were the 2500K or 2600K, then I'd be saying that it's just average.



Hey,

To me, there's no sense in stability testing 95% of your RAM, especially if you are running more than 8GB's. I believe the OP'er is using 16GB - practically there is no sense in trying to use that much RAM, knowing almost every application doesn't use more than 6GB's maximum. Including intense RAM programs like BF3, or video editing software. If I was him, I'd only test about 50-75% of his RAM. Use 12,228MB's of RAM during the p95 application under the custom mode. And, try and really throw the CPU some stress and decrease the FFT time to about ten minutes, and up the FFT size to something like 8192K max and 1024K Minimum.
