Since some people seem to see need IBT stable screenshots.

1.375V at 3.8GHZ stable.
:rolleyes:
 
Ok, since you're obviously not going to accept my overclocking, since even 5 run IBT stable isn't stable enough for you, I'll do 10.
Give me a few minutes.
 
Ok, I'm running 10 now, I haven't restarted since the previous 5.
I'm currently on number pass 5, temps are still no higher than 49C.
I'm probably going to lap my CPU/T.R.U.E next week, since they scale better with cold as opposed volts, which is why you're now 1.425V stable at 3.8GHZ.
 
20 minutes is nothing, I give you 15 loops in five hours.

And the damned thing still isn't stable. It's barely stable at 4ghz yet it'll pass obscene amounts of prime and ibt at 4.4, absolutely doing my head in.

u have 12gb of ram thats why it takes a lot longer.. the more ram u have/use the longer it takes but gives better results u get

2. Use the most available RAM possible (IntelBurnTest can now do this on
its own automatically). The more memory it uses, the more accurate.

from the Readme-IntelBurnTest

If an intel cpu can pass five hours of this test then crash in normal use, I am quite happy inferring that a 20 minute stable amd cpu may also crash in normal use. The processors aren't so wildly different for this to be an invalid concept.

Thank you Gareth. Believe it or not I did notice the increase in time per loop as I put more ram in the machine, and indeed I have read the readme. It remains that it ran this code for five hours without complaint before falling over on what I thought was a simpler task. I suppose I could have run many more loops with only 6gb installed, but this wouldn't have been particularly useful to me.

My point here is that ibt is not an especially reliable indicator of stability, I thought I'd provide an example rather than just write "not stable cos I don't think ibt is good enuff to stand alone, test more".
 
JonJ678 , it may not be your cpu that making your system crash though.
if 5hours is stable using ibt and prime95 , then u should be looking at other parts of your system.

a crash doesn't just mean it's down to the cpu..

Interesting point that one. I'm inclined to blame the ram, but it passes memtest and should be pushed pretty hard by ibt. Otherwise it could be the motherboard, but other UD5s have run significantly higher clocks with no issues. Which parts do you think I should be paying attention to?

my ram passed memtest but i was getting random crashs so i underclocked them which worked fine, so i rma them, now the replacements are better, no crashs at 1600mhz 8-8-8 20 1t. even though it should be 7-7-7-20 2t but that crashs so they still not 100% right.

it could be many reasons, bios, ram, motherboard, drivers, software issues, psu, ect.
