What's the best cpu stress test other than prime95?

Stories and rumours. It's long-term voltage which damages a chip, not the heat itself.
IMO, if it can't pass IBT (max memory, 100 loops) it isn't stable. This means keeping temps in line. There was another member here who found errors after 70 and 80 loops.
The standard memory level is from years ago when more than 2 GiB was rare. With an 8 GiB machine you need to give it the majority and get the GFLOPS as high as possible (120+, depends on clock. As a rule of thumb, 80% of 32 times the clockspeed).

have no idea,its down to your cpu,seems abit high for 4 cores though,tried to lower? offset will help and chose the right llc level
I have no idea how to use offset unfortunately... what's the basics of using offset instead of manual voltage?
Caporegime
just set cpu voltage to offset and use high llc,remember to use only tiny amount of offset this gets added to your cpu voltage at load
for 4.5ghz on my gigabyte board i needed +0.0010v offset,so you would need to experiment and load cpu-z and stress the chip,then see how much voltage is used for cpu,adjust offset if needed ect
lower llc levels means more offset needed,higher llc levels means less offset needed

lower llc levels means more offset needed,higher llc levels means less offset needed
So basically keep my current settings with the adjusted cpu voltage but enable offset and add the amount needed to stabilise the overclock with high LLC rather than ultra high LLC that i currently have set?
I just played supreme commander for an hour and it crashed
so i guess i should try offset

you set the cpu voltage from manual to offset dont you on asus? cant remember off hand,then see the default cpu vid(voltage) and take into account what the llc levels apply and add a little offset,remebr only tiny amounts as you dont wanna overvolt the cpu at loadgo up in +0.0005v increments and test ect but you shouldnt need much,maybe +0.0010v to +0.0020v max depending on the llc level,keep all c states enabled as the cpu will downclock itself at idle in speed/voltages and full speed/voltages at load

exlains it all best to set it custom to 200-300mb below free memory IBT that is

I use good old 'use the system for 6 months and see if it ever crashes' personal tests but yeah usualyl just prime for a quick check to see if pc is likely to implode from new overclocks.
Okay i did this, i set offset mode and set my cpu base to 46 for 4.6ghz then set offset to +0.010v and saved and it blue screened! When i went back into bios it said my voltage was sitting at 1.1v :S
I don't get it at all, to achieve 1.3v would i need to add an offset of something around +0.2v then?
Caporegime
No because llc adds extra voltage,how much Idk,just either use a higher llc or more offset,but only a bit at a time
Right i did what you said, i read a guide too.
I set my LLC to high, set turbo core to 4.6ghz and left all power saving states on.
Set to offset mode and restarted. Looked in cpu-z and did a quick run of prime and my voltage shot upto 1.5v!!!?!?!
Cut the stress test straight away and tried to adjust offset to counter it but i dont think i can even go that low to reduce the 1.5v needed for 4.6ghz by default lol...
Something is seriously wack!

It's llc that sticks a big amount on,it varies from board to board,you can undervolt in offset with -0.0010v ect,you need to find the right balance of llc level and offset amount
Caporegime
Keep trying as it works fine once you find the right setting,for me in a z77 gigabyte board for 4.5ghz I use medium llc and +0.0010v offset but your llc levels might be different on that board
Caporegime
I don't know,just start off low and gradually add more offset,
