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

Get it past a couple of runs of Intel Burn test on max stress level and it will be able to take anything that is thrown at it.

IBT had my [email protected] to 96c!
Currently have an i5 760 @4ghz upto a not to smokey 86c

is medium on your board around 25%?

I have same board mate, I found it very easy to get 4.5 perfectly stable by just clearing cmos, set up what you have your drives set to, enable X.M.P for your memory, set the multi to 45 and F10 and save and exit, I found there was no need to mess with anything else, 4.6 would blue screen after a while with them settings, so I never really bothered to take it any further for 4.6, i just dropped back to 4.5 as there really was no difference.

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!

I have exactly the same issue that you do Jay85, Often the Volts rocket to 1.450 and above, and often I've had to add a + Offset of 0.145 and above to even get passed Blue Screen at Boot for a Turbo Ratio of 45 or 46. If I boot into BIOS and look at the Volts next Vcore it usually states 1.288 if I set 45 and above. I also elaborate with steve258 I cant get passed 2 hr with Prime either worker 2 also stops for me.
 
Can you help me with this? and tell me if I'm going in the right direction, or if I'm totally off target!?

I set everything in bios to optimized defaults, rebooted, went back into bios, set X.M.P, Turbo ratio 44 and rebooted, I touched nothing else just those 2,

Then I launched CPU-Z on the desktop and the Core Voltage reads 1.256V. I then launched Core Temp and the VID reads 1.0358 v. Frequency on Core Temp reads 1600.04 MHz 100.00 x16.0 CPU-Z Core speed 1600.00MHz. How do I achieve bringing the voltage in the 2 Apps equal? Someone said that I take the core voltage and minus the VID? so if I subtract 1.256 from 1.0358, = 0.2202 ?? that cant be right surely?

this is with a 3570K btw.
 
No that's wrong,you'll overvolt the CPU,its right but your missing out what llc adds,I have no idea on how much each stage adds its this that bumps up the CPU load voltage on top of what offset adds,best advise is to start off low and a little at a time,and keep the first two offset digits as 0,so +0.0....v ect
 
zep, cpu-z will tell you what voltage the cpu is getting, core temp will give you the VID at the current speed of the cpu, two totally different things, do not worry about VID in core temp.

1.256v for 44 ratio is fine, try running something like prime95 to test and keep an eye on temps, you don't have to mess about with off set voltages.

I set turbo ratio at x45/ llc ultra high or 75%/ offset 0.080
running Prime95 as I write this and cpu-z core voltage is 1.288v ~ 1.296v Core speed 4532.67MHz Multiplier x45 Bus Speed 100.53MHz.
Almost at the end of the first 8k test on Prime95, Max temp reached so far on Real Temp: core 1 = 69c
2 = 79c
3 = 76c
4 = 71c

hopefully this will get prime passed the 2 hour mark, as in the past worker 2 fails after 2hrs 15mins no matter what I set with a ratio of 45

After 40 mins CPU-Z has locked in the Core voltage at 1.288v and this remains steady, no drop or raise.

Does this sound fine too you? btw I'm running Prime test with blend.
