2500k temp/load problem - Page 2

post #11 of 16
Check your vcore at load, because it may be dropping from idle vcore if you aren't using loadline calibration. Ideally you want stationary or very low drop (less than 0.05v). Having the vcore RISE under load with a high setting LLC (some boards do this) could be potentially bad for the CPU.

And, yeah, 1.5v for 5 ghz is about average for a 2500k. The golden and super rare ones can do it at 1.35-1.4v, and good ones can do it under 1.45v.

My vcore rises under load, it went from 1.320v to 1.360v (at 4.5GHz)

I couldnt get it stable at 5GHz below 1.5v so now i decided to go abit lower.
So far i'm at 4,5GHz @ 1.32v temps is around 35-49's idle and low 50's at prime95 blend.

It's because you're on an MSI board, the malfunctioning LLC is a known bug.

Ok

How are my temps?
I'm at 4,7 GHz with 1,35v now.
  • Idle is around 43-49
  • Load is around 57-59 after two hours prime95 blend
Monitored with RealTemp.

I think my idle is pretty high, but load is OK?
Considering i have some decent watercooling i would have expected it to be abit better. Maybe i should try reapplying thermal paste.

My WC setup atm is:
240 mm rad
2 x Scythe Gentle Typhoon
Apogee XT for CPU
MCP655-b pump
Some special silver thermal paste, cant remember its name but it was expensive.

It's good compared to air cooling, but I don't know how water cooling performs.

Your idle temps are a bit high. I get about 30~ on a rasa kit. Voltage probably isnt dropping at idle. Do you have c states and speedstep disabled? You also need to use offset vcc which is a bit tricky to change to if you're using manual. I have an Asus board with llc set very high (75%) and my offset is 0.03 for 1.375 vcc.
