Ok, to start. The OC profiles generated by DRAM speed are never great to use. You should set it back to stock for now. Then after you get your temps and OC sorted out you can change the DRAM Divider from x6.33 to x8 (x8 x FSB of 200 ='s 1600Mhz)

So put everything back to stock settings. Disable Turbo and restart the computer.

Then let me know what the CPU temp is in the BIOS now.
Also, what is the CPU Voltage listed in the BIOS with Turbo Disabled?

Oh, I didnt ask Raven what his stock temps were but I told him my situation and after asking me to check heatsink mounting and BIOS version. He said that he would not trust a 970 based mobo to power a vishera chip. That the 990fx boards were designed for it intially

You wont get a great OC out of most of the 970 Boards unless it is one with Heatsinks on the VRM's. Because of the power draw, it taxes the VRM's on any motherboard and without cooling they will hit their temperature protection limit and shut the computer down.

Your model shows that it has heatsinks and 8+2 Phase VRM control. So it should be decent with good case airflow

Ok, give me a few mins to swap the chips back out. I put my 945 back in last night and just now getting a chance to work on it. I will post back in a few.

Want me to disable CNQ, c1e, APM and c6 with turbo as well? or just turbo?

EDIT: i was off on the HT and NB as well. Stock they are at 2200 NB and 2400 HT. With turbo on CPU V in BIOS is 1.424. With turbo off its 1.360. Temp on is 34 and off is 31.

yes, everything on the cpu adavanced tab and the turbo core

Done, Bios reports cpu V at 1.360 and temp at 30c.

HW Monitor readings:


CPU Vcore Current 1.34-1.36

Socket Temp: Current 26 ( i have my side panels off at the moment)
Core temp 15

This is with all power saving off and power profile set to high performance just to be safe.

Those temps are holding at idle. I have not tried P95 yet. Gonna put the sides back on and check it again after I clean up my workstation

Also note that the temperature readings at idle are not very accurate. It is only under load that temperatures read right on the CPU, except for the reading in the BIOS

Ok then, a couple things.

If you have an ambient temperature of 70 Fahrenheit (or 21 Celsius) because the BIOS has no load on the CPU, so the cooler should be able to maintain a temperature near Ambient. The temp reading in the BIOS is the most reliable for this.

So your temperature right now is ~9 Celsius higher than it should be in the BIOS. So you should start by re-seating your CPU cooler, because this ~9 Degrees difference means that the heat transfer under load will be really poor. It might not read right at 21 Celsius in the BIOS, but it will be a lot closer to 21 than 30

A lot of people will recommend the pea size Thermal paste, and then squishing it under the CPU cooler. This works great for Intel CPU's because the Integrated Heat Spreader (IHS) is almost half the area of an AMD IHS. Thus, the Thermal Paste to pressure ratio is different and it's ability to evenly cover the entire IHS.

I generally use the method of placing the Thermal Paste on the CPU, and then making a thin coat evenly accross the whole IHS with a Credit Card. By thin, I mean about the thickness of paper, maybe a little thicker.

Also make sure to clean both surfaces with Rubbing Alcohol to make sure they are really clean. I know the 212 coolers come with a large sticker on them that leaves a film that will actually block heat transfer.

Once you have the temp issues sorted out, you could start overclocking with your DRAM settings left at 1333.

You should be able to increase your Frequency by about 400 Mhz at the stock voltage of 1.36v. If the temps are ok. Then you can go from there.

Let me know how it goes. I've spent 100's of hours playing with my 8150, but will not have my hands on a PIledriver for a bit yet

The ambient temp of my room is about 69 right now. The ambient temp of the case is the same as the socket temp of processor right now in HW Monitor. This happens to be 27c or 80f. My problem was p95. Even with those low temps when i started p95 my tmps would rocket to 57-60c ( socket) with my case fans on high. I am actually getting ready to try it again.

What case are you using and how is the air flow in it? That could be the problem.

**Important**

AMD CPU's do not have thermal sensors and especially not core sensors. The core temperature readings you see are calculated values and will almost always be 10-15 degrees lower than the actual temperatures. Therefore, you should always go by the CPU, or "socket", or "Tcase" reading since it is a physical sensor on your motherboard. That sensor is right underneath the CPU socket and because of that it's usually a safe assumption that the inside of the CPU is several degrees warmer. This is why AMD CPU's need to stay under 62C (in monitoring software) whereas Intel's safe zone stops at around 70.

As far as the temperatures you're seeing you may just need to go easy on the Vcore or get new cooling. I've got an H80 which is a decent CLC, but with just 1.35V I was seeing Prime95 load temps in the 50's.
