Questions about Bulldozer voltage specs... Need Help!!!

post #1 of 2
Thread Starter 
I am having issues with the FX-8120 stock voltages. I have received 3 8120's in the last month and none of them had the same stock voltage.
Big differences in overclocking ability, thermal production, and stability.

Please help. I would appreciate it if someone who knew what they where talking about would give me a call about this situation as I have a lot of questions and dont really have the time to sit in front of the internet and wait for answers.

If someone is willing to help me over the phone regarding bulldozer voltage specs, please send me a message and I will either call you or you could call me.

Please help!!! If you do not feel comfortable calling someone I will try to do this over the internet but I am really trying to get answer and resolve this right away.

I will give some details regarding the voltages of the 3 same chips I have received.

Chip #1 (Out of the Box):

CPU Voltage: 1.325v
NB Voltage: 1.3v

I am not sure about the NB voltage on the above chip because I have not had any problems with this chip and its performance or overclocking.


Chip #2 (Out of the Box):

CPU Voltage: 1.275v
NB Voltage: 1.1v

This chip would not overclock to 4.0Ghz so I returned it right away and did not spend much time testing it. The chip heated up tremendously at stock frequencies. I knew there was something wrong with the chip so I sent it back right away.


Chip #3 (Out of the Box):

CPU Voltage: 1.30v
NB Voltage: 1.125v

This chip says 1300mV in bios specs but runs at 1.38 with settings at stock read with multimeter. When doing testing the voltage jumps around a lot. It went down to like 0.6v all the way up to 1.42v on stock settings. I was able to overclock to 4.8Ghz but not stable. I could not overclock to 4.0Ghz without increasing NB to 1.4v to get stable.


I could really use some help here and I am questions the quality of these chips seeing that I have received 3 of them and the voltage specs are different on every one. I could understand that sometimes there is a bad chip and it needs to be sent back but 2 out of 3 in the last month is a little rediculous. The first and second chip where from the first batch of 8120's and the 3rd chip was from the last batch.

Please help... I would much rather talking to someone over the phone that knows a little about what they are talking about when it comes to amd cpus and their specs.

Like I said above, please send me a message and I will either send you my number or call you, whatever you prefer.

Please help though. I woud really appreciate the help here.

I remember reading about this. IIRC it's just how the chips are. The higher the stock voltage the better the OC and the cooler they run. Just luck of the draw.

1.3v and up is supposed to be good. Your first chip was a keeper.
