AMD 7750 oc weird

[cpff33]

so guys all i did is bump the multi up to 16 and stock everything else it seems stable im posting it now temps are at 30 max with my artic 64 pro im just worried how can it be thats east i have a gigabyte 790x ds4 kingston hyperx ram 1066 running at 800mhz 555 18 2t so am i just lucky or am i missing something

My 7750 also overclocked to 3.2 (3.24, because mine was not a BE chip, so I had to go through the HT ref clock, keeping multi at 13.5), so the fact that it reached 3.2 is not strange.

As for the temps (I am assuming your ambient temps aren't 10C or less) it just means the software is reporting the temps wrong. What are you using to read the temps, and what did you use to get max load and test your OC?

There are also other software you can use that shows temperatures, one of them might be more accurate than what you are currently using, such as CoreTemp, OCCT, etc.

yup, sounds like you're software is reading it wrong. The software in my ASRock A780FullHD board has the CPU temp off by 20* on mine, but the CPU0/CPU1 temps read correctly. Mine never breaks 50*C under my Sunbeam CCF 120 at 3000mhz/1.2875v. I decided to leave it there because the voltage ramp on the Phenom 1s are pretty extreme (especially since the board that I bought for $40 didn't have the SB710) I can do 3085mhz at 1.3125v, but 3.2ghz isn't even stable at 1.5V for me.

guys i know what my temps are there 30c max ok...i used 3 diff programs were good i just dont know how to efficiently stress test how many programs i should run all at once or just one at a time i wanna make a quick stable test dont wanna wait 8 hours

 

[cpff33]

ohhh and sorry did i mention it was a black edition people have been telling me you dont have to worry about voltages for the be's

Let me explain something to you. 30*C is 86*F. Room temperature (72*F) is about 22*C. Modern CPUs have a higher energy density than a Nuclear Reactor. My overclock is probably more conservative than yours (you never listed voltage which is CRITICAL to figuring out cooling needs) and I have a better heatsink. My CPU Cooler is 3lbs. of copper and aluminum with a 120mm fan hooked onto it. I STILL have higher temperatures. TRUST US, YOUR TEMPERATURES ARE BEING REPORTED WRONG.

Oh, Really? if that's the case then please change your Vcore to 2.0V and report back to us about what happens.:thumbsdown:

Otherwise I'd reccomend reading up onhow a CPU works, How to overclock, what voltage does, and what a Black Edition processor is and how it can potentially make overclocking easier for you.

my voltage is stock ...

I have a 7750 paired with a Freezer Pro 64 too. I'm also at 3.2GHz on stock volts (small world), and I idle at 39-42C, depending on house temperature.

Also, you're going to have to wait at least 8 hours. 13 minutes isn't anywhere near stable. Just leave it on overnight or something.

Thank you. Note that 'stock' isn't one voltage, it's a range of voltages: http://products.amd.com/en-ca/DesktopCPUDetail.aspx?id=506 Stock is 1.05-1.325v Your board seems to default to the very top of 'stock'. Voltage is critically important to the amount of heat generated. With processors Heat = (Clockspeed) * (Voltage)^2.
You're probably putting out about 120w of energy during stress testing with those settings. Disapating that much power with just a 12*F delta between the processor and ambient is extremely doubtful given the laws of thermodynamics.
