Upgrade to PII 965 (sangria)

[sangria]

Well i tired some of the options. So when i use AMD Overdrive with the factory settings Core tempratures getting 58-59C but the CPU gets 50C. (I am also using HW Monitoring and CoreTemp RC8. WHen i use 19x200 . Core temp getting 60-62C and CPU about 56C. SO which one is more important? CPU or Cores? Everyone says Cores? So if this is the case my cores are 58-59 under load. So it is not good for a stock speed then?

Give us some screen shots, run prime blend with Hwmonitor open and then post a screen shot of Hwmonitor and the following tabs in Cpu-Z, Cpu, Spd and Memory. It will give us a peek under the hood so to speak.

Those are the numbers with stock speed 3400

Looks like you might need to get some better cooling on that CPU with a better heat sink (probably an aftermarket one).

It's running pretty hot for a Phenom II, you're hitting 58°C on the cores, but really you should preferably be under 55°C. Note: Phenom II CPU's tend to get unstable between 52-55°C, but some can get unstable at 50°C. It's running the CPU fan near maximum speed too as you're getting it up to 4400 RPM under load. Stock cpu heat sinks (either AMD or Intel ones) don't tend to be very good at cooling the CPU with reasonable temps, so it's not surprising to me that your temps are a bit high.

mm. Thank you for the quick response. I purchased AMD FX 8350 cooler which has faster fan and it came with the pre paste. So I wasn't expecting to get that much heat with the FX Original Fan.

Actually it looks like the board is giving the 965 too much voltage 1.464 v seems a bit excessive for stock clocks. Click on the Cpu-Z motherboard tab and see what BIOS you're running.

 

[Mr.Scott]

1.4-1.425 is about normal.
My guess is LLC is on auto.

 

[ShrimpBrime]

0.825V - 1.4V according to cpuworld. http://www.cpu-world.com/CPUs/K10/A... Edition - HDZ965FBK4DGM (HDZ965FBGMBOX).html

If I remember, these will do stock at 1.35v normally and sometimes max p-state request 1.4v

I'm running Opteron 1389 right now. 3ghz @ 1.236v (It did post scotty yay!) So I don't see why it would need more than 1.400v to operate at stock 3.4ghz. This opteron also is a C2 stepping, generally requires more volts at similar clock speeds.

I'd manually set voltage to 1.350v and disable LLC if it where mine.

 

[Mr.Scott]

Both of my 965's set 1.4 at stock.

Nice. Should still be able to under volt this 965BE C3 with ease.

Here's an example. representing load temps on air cooling. P95 in the background.

 

[ShrimpBrime]

Here's 3.4ghz at 1.40v representing air cooling loaded P95. Couple of minutes into prime, not a 20 minute run yet, but for temperature comparison purposes only here. Thermostat reads 73F on the wall.

 

[ShrimpBrime]

OK 3.4ghz with 1.310v and LLC on auto. One hour represented Prime95 with max temp of 51c on air cooling.

 

[sangria]

Mmm. Interesting. So I never knew this infos before. Thank you for the details. So what do you guys want me to do? Change the voltage?

And I got my led project done today. I would like to share some pictures. Total cost was $13

Why your voltage is lower than ours? And what do you use for cooling? What brand I mean?

 

[Johan45]

Looks good sangria, his voltage is lower because he set it lower. He's trying to illustrate that when voltages are left at auto along with LLC then the motherboard will usually put too much voltage to the CPU which causes more heat. It's possible if you were to make a few settings you could drop your voltage a bit and keep the CPU cooler.

 

[sangria]

Thank you Johan. So I never done that. Can you tell me how can I adjust the settings? And if I OC the CPU, how does effect the performance with the lower voltage setting? Thank you

To start check out the guide in my sig it'll help me help you.

Ok I changed the Voltage from 1.416 to 1.3683 which automatically jumps to 1.3750 on AMD Overdrive app. Anyway I used the Stability test and the fans not even turned on fast enough to make the noise. And the temperature did not pass the 51 on Cores! Here is the screenshots :




My question is Does the performance still same even you lower the voltage? If so Can I increase my CPU Multiplier with the same Voltage? Or what is the best manual voltage for 965BE for Multiplier at 19 or 20?

I want 3800 or 4000 if it is possible

Nope performance will be the same.

nice job with the under volting. looks really good now. If you want 4000mhz, you may need liquid cooling.

The cooler I am using is a 2U server cooler for 2nd generation Opteron.

I'm actually cooling an FX processor with this right now.

 

[sangria]

Can I do 19? I mean I was doing with the Auto Voltage option but the Core Temp was about 61-62F and the CPU was about 51F I guess I do not recall right now. So if I increase the multiplier probably I will need more than 1.368 how about 1.4 with 19x200?
