Which is the better deal? An AMD Propus 620 for $99 at Newegg or A Phenom X3 720 for about the same price. I am looking to use the GIGABYTE GA-MA790GPT-UD3H mobo and may later add additional discrete graphic card.
I don;t do games, but I do photo/video editting, Blurb, Adobe 3D pdfs, etc.
Are all 720s unlockable? Is it a slam dunk to succeed?
I can across this thread while I was searching for the answer to this question. It appears (after hour+ research) that the only Phenom x3s that are pretty much garunteed to have a functioning 4th core are ones purchesed when the processor first came out, and nowadays theres a good chance the unlocked 4th core will be defective. It is also true that not all motherboards seem to work for this, even if they have the feature (ACC) that you need to enable to unlock. Despite this knowlege I am going to attempt an unlock on a phenom Im getting this christmas with the exact same motherboard as youre getting so I can tell you how it pans out. Even if the 4th core doesnt work, the x3 with three cores will still meet my needs handily, which is why im taking the risk (it overclocks like a dream apparently as well).
I unlocked mine with the same mobo you listed there, and I just bought them both on black friday. It is very easy to do in the BIOS, and overclocked as well to 3.2GHz. Temps on Prime95 are about 57C in that configuration with the stock cooler.
I too, bought the same combo: AMD Phenom x3 720 Black (Heka) w/ Gigabyte MA790GPT-UD3H Mobo from NewEgg on Black Friday. Last night I was able to unlock the 720's 4th core and now it shows it as a 940b (Deneb) using CPUZ. Running Prime95 for 10 minutes, I got it stable at 3.2GHz at above 55C on AMD's stock cooler . Core voltage set on auto/normal has me at 1.360v, I just slowly ramped up multiplier from 14 to 16.0. Nice!
