IntelBurn vs. Prime95 - Page 2

post #11 of 21
IBT stresses your CPU harder than P95.
I do a few runs (25 @ Normal -> High -> Max) on IBT to see if it's worth it for me to do an overnight P95 test.
post #12 of 21
Ibt stresses the CPU much more, but prime stresses the chipset more, and takes longer. You need to use both really.

If you are doing a small oc just upping the fsb a bit, and leaving the voltages, timings etc alone, ibt is probably the better test.

In my experience prime is more sensitive to errors than any linpack test.

But like everyone has said, nothing wong with using both.
post #14 of 21
I recommend 20 passes of IBT on high to get a feel of things, then run Prime95.
post #15 of 21
Idk, I just do 50 runs of IBT on max and call it good. Hasn't failed me yet, but nothing I do really loads my computer to the moon; all I do is game.

I run IBT until it fails. My system lasted a little over 10 hours at 4.25 running Max IBT (5400 some Mb), I ran prime blend for 12 hours and never had a fail, got bored cause I already did IBT, and quit.

I think this 20-50 runs is a rough stability, I did that when I walked mine up to my vcore limit (1.4v). If you want IBT to actually tell you much, you should set it to something like 500 runs, and just let it go til it fails or finishes. This will give you a better idea of your true stability. (Warning, make sure your cooling can handle it. If your temperatures creep, don't do this!)

EDIT NOTE: My system, under water, creeped 3 degrees (65ish-68ish) doing my IBT suicide run. If you are on air, this may be a serious concern.

I'm actually one of the few to do this; but I use OCCT 2hr CPU test to check if my overclock is relatively stable... and if I like the temps and the voltage and speed... then I go for prime95, which is definitely takes longer, but finds most if not all errors after 24hrs.

So I recommend you skip IBT altogether.

I find linX makes the cpu temps a little hotter then IBT, but either of them are good (10+ passes on max mem) for a quick test of temps and general stability . then use prime on blend for 8+ hours.
post #19 of 21
Here's my 2 cents, after I adjust my overclock this is what I do:

at least 3 passes of memtest86+ (so I know my RAM's stable)
then I do 50-100 runs of ITB on Maximum.
then I confirm with 6+ hours of Small FFTs

All you guys saying to run Prime Blend are doing it wrong. Blended will only use 1600MB of RAM by default. You have to click "Blend", this way it forces Blend settings. Then click on "Custom", and force it to use at LEAST 3/4 of your memory.
