Testing / comparing : Intel D975XBX2 / Asus P5B DX ***56K WARNING***

Bingo. Your DMM reads low or your sensor chip reads high. I'm betting it's the DMM.

Ok..I have not gone back to the BIOS readings

I bought a second DMM(sears has a nice one for $12)
http://www.sears.com/sr/javasr/produ...TOOL&ihtoken=1

I tested both DMM on batteries(gave exact same readings on AAA/AA?C batteries) and my system

From post #3338..I cant recall but I may have used a molex that was fan only as a ground and with both DMM this gave a reading of 1.46/1.47v underload

From my previous post:
BIOS Readings(vcore set as 1.525v with powerslope enabled)
12v= 12.375
5v= 5.058
3.3v= 3.353
1.5v= 1.607
Vcore= 1.535


DMM #1 Reading (hmm now that I think about it, I was using a molex adapter from attached to the 4 pin that went into GPU molex on the mobo)
12v= 12.10v
vcore= 1.49v

I have a 4pin molex cable with 2 plug one into the gpu molex on the mobo...I had previously used the free one with a molex adapter so I could see color of the wires..the cable on the HX620w are all black

so this time no adapter just used the 4pin molex and I used one of the inner plugs as ground...tested 12v line DMM #1 ..12.10/12.09v...new DMM 12.13v

OK so grounded and test at the same power choke..upper left one in pic from Gtj link
Bios 2333
Powerslope enabled
vcore 1.525v as bios setting
load is P95 v251 blend

speedfan 4.32 .... reads idle of 1.54v/load 1.53v
DMM #1
1.50v idle/1.50v load

New DMM
1.50v idle/1.50v load

so the difference vs speedfan is .03/.04 this time

so unless both DMM are bad...I am pretty happy my DMM readings are accurate
