My new build with a Rana 445 95 Watt CPU reads 105 Watts with the stock 3 cores active. Once the stable 4th core is activated it reads 140 Watts. In both cases that would equal 35 Watts per core. My motherboard supports up to 140 Watts so I am not worried about the MB but I am worried about frying my CPU.
Can I lower this to 95 Watt on 3 cores or 125 Watt on 4 cores? If so how do I achieve this?
Do I need to worry about damaging my CPU with these higher watts? My core voltage is within limits. (1.4 max)
AMD Rana 445 95W CPU with 4th core activated (sometimes). Propus die.
ASUS M4A87TD/USB3 Motherboard
The only things I have changed i bios is the memory clock (was default at 1333 but rated to 1600) and activating the 4th CPU core. Every other setting is default.
I also receive a rare BSOD, could over wattage be the cause? I have run prime 95 for 10 hours with no issues. I have also received no memory errors with memory tests. My temps are cool 29C idle 43C under stess.
If the cpu was designed as a quad core, and the mainboard supports quad 130 watt quad cores, you will not damage it as a result of running the hopefully-servicable 4rth core...; you might want to investigate what voltage is for a stock quad core, you might need a slight v-core boost for reliability for the 4th core unless your MB has boosted it for you....
Running 4 instances of Prime95 should tell you within an hour if the 4rth core and it's cache are serviceable...........
However my original question hasnt been answered yet. Why is it showing 105W on a 95W chip? Is something not set right in bios?
If you dropped the volts back and that 105w reading did not budge: Do not trust that reading. Dropping from 1.38v to 1.35v should have got yah something.
When you unlock a core your readings do get borked. It's as much a 'feel' thang as anything else. Best thing to do is compare readings when locked and unlocked, and then use your best judgement on where you stand.
