When i put 6700K into optiplex 7040 sff and turn on torture test in prime95, i can read parameters in cpu-z:
frequency: ±3,4GHz
power: ±65W
±4GHz if only 1 core is under load
These values are same/typical for 6700 non-k (6700 has a base clock 4GHz, 4,2 Turbo and 91tdp). I think that mobo in 7040 sff is choked to 65W TDP and i wonder if this limit can be increased trough bios editing.
I`m totaly aware of treats like a mobo blow up. Sky is the limit c:
You can set these in UEFI or in the OS itself. Try Intel XTU so see which values work before changing them in UEFI or mod your BIOS.
"Curret/EDP limit thtottling" in xtu has yellow color and displays YES, so i think there is nothing to do in xtu
BUT, actualy yes… idk how to send picture here, but ive undervolted my cpu (-0,17) and increased current. Now i
m able to reach @3,98 all core in prime.
So, thank you very much stovorsen
You’re welcome! The available options in XTU differ per cpu generation. Smart move to undervolt to lower temps enough to run at max speed. Easier than replacing thermal paste or install a new cooler too haha.
