Overclocking a AMD Phenom II X3 B73 I have a couple noob questions.

post #1 of 4
Thread Starter 
I am overclocking a AMD Phenom II X3 B73 on a ASRock N68C-S UCC. Now I know it is not much but I still want to have fun with this one. For the time being I am using the Stock Cooler, so I am aware I am not going to get very far with that.

So Basically what I have done was do a 10 Minute Stress test using Prime 95 on each of the possible settings my PC would Boot off of. I did this just for the sole purpose of collecting data. To see the differences in Temps for each OC Setting. Unfortunately I did not see MUCH difference? I used SpeedFan to gather the Minimum, and Maximum CPU TEMP, and Core TEMP. Of course I could not document the CORE temp after I unlocked the CPU to a X4 core due to the bug of sensors being disabled.

Anyhow, here is the data I gathered:




So what I am trying to figure out here, is how come there really is not much of a temp.increase for faster GHz, and even an extra core unlocked?


Anyhow, what my next step is, I am going to do a longer Prime95 test for the better speeds, and if they fail I will try lower Until i reach my Ultimate Stable


TLDR; How come there really is not much of a temp.increase for faster GHz, and even an extra core unlocked?

It may have to do with your voltage and whether you are actually raising it or not.

 

But I would stop where you are and not work with any unlock to x4 (which makes your B73 into a hungry 125W Deneb) or overclock that. The N68C-S UCC is an old AM2-era chipset and VRM board that uses a very weak quality 3-phase VRM that is absolutely NOT meant for quad core processors. A quad core 125W Phenom II x4 requires a quality 4+1 phase VRM and VRM cooling. You have the VRM cooling in check with your stock cooling but with 3 phases you are NOT going to get the capacity for safe operation. You should stop the OC, stop the unlock and pursue stock speed operation until you can get a new motherboard where it is safe to be doing all these things. Read the thread - VRM & MOSFET Info, link in my sig.

Awesome, thanks for the reply. That is really a bummer. But it makes sense, If I am using cheep equipment, then I'm limited to what I can do. As far as the voltages, I wasn't messing with those, I just left them on AUTO and they ranged between 1.41 and 1.42 on the Vcore.

Anyhow, since this info you gave me, I dropped my CPU down to a X3, and did a VERY mild overclock... I have it @ 3.0Ghz, ( 215Mhz X 14 Multiplier) and will just deal with this.

Also, Why would companies make motherboards with such features that are not safe to use? Such as UCC, or cheap boards with overclocking features thinking.gif... This only leads to noobs like myself ruining their equipment.

I honestly think it may have to do with trying to get rid of this massive surplus of old AM2 chipsets. They're like, 7 years old, why else would they still have em..... you might as well make some money with the near-worthless? That including.... the cheapest mobo components including weaker VRMs perhaps
