post #11081 of 19539
So after trying to get 4.5 today, i'm getting machine_check_exception randomly. Did i goof?

Yeah I posted a link to the new one in my reply to Front side.

System works using this setup and is around 65C-70C on benchmark under full load.

Unfortunately... it goes into BSOD as soon as I try anything under 1,2Vcore.


You should set the cache voltage to 1.2 for testing purposes (just to rule it out until you find the vcore), and then lower it to whatever it’s needed.

Both the CPU fan error and the loud bootup noise won't disappear, not even on default settings without overclock frown.gif


It sounds like the MB can’t read the CPU FAN speed (or presence), and when that happens the mobo sends full 12V to the fan.
Swap the cpu fan with another and restart, to see if that still happens. If you have two fan headers for the cpu, try them separately (the one with four pins first).

Passed from Aida to IBT.., that’s like passing from kindergarten play to SAS special training...
You need more “stamina” for that.
Joking aside, if you want to stick with synthetics you need to test prime large fft’s (like custom 1344 or 1792) as mav451 already suggested, because it’s not as hot as small fft’s or IBT, but definitely more relevant then aida.
And also, if you want to test for heat, LinX (latest) is better than IBT (latest).

Read the guide (first post). Because, in order to find what your cpu can do in terms of multiplier and voltage, you need to take out as many variables as possible out of the equation (like cache on manual muli and voltage, ram on 1600, VCCIN at 0.5V above VID maybe 0.6 if you use integrated graphics, etc.).
And then, when you found the limit of your cpu in terms of voltage/heat, you can start fiddle with those as well (with testing after each to see if it messes with your OC).

Why is everyone new to thread still using the latest versions of CPU-Z with the wrong vcore sensor wth.gif

I mean not a few, but like dozens of people. I've said this every day for 6 months

Are you sure your programs giving you the right reads?

Stock voltage von 0.974 under load seems awefully low tbh.

Although your HWM shows nothing for VCCIN, 0,0 for VRIN and 1,88 for VCORE, kinda strange. Or are my eyes crossed and I don´t see right?

My chip can boot with nearly every multiplier I throw at him at relatively low voltage but under stress it crashes.
Aida is really an easy stresstest. I only use it with the FPU stress feature to get an idea of the maximum temps.

I would recommend, OCCT:CPU,x264 for a few hours or Prime with custom settings to 1344 and 1792 like other in the thread suggested already. smile.gif

What are your other settings? VCCIN,VRIN,SA Voltage i/o vol ?

Tweak a little and got both the vcore and the vring down. vcor now on 1.28/1.30 vin

What do you mean exactly?

1.68 is the latest version and it works fine for me. Checks out with my readings in HWM and my settings in the BIOS:

All older versions showing the wrong numbers, like as VCore the fixed number that´s set as VID

For most motherboards, versions after 1.64.0 show VID instead of Vcore. It works for some people but not all and i see screenshots with people showing their VID all over the place
