Nice 620 chip you got there drfedja , what is the batch if it's not a secret? It really outperforms Propus core without L3 cache, in overclocking and in clock per clock comparison

msgclb, unfortunately Deneb based Athlon X4 cpu's are very rare , better chance in finding 550 X2@X4 for the same money and they are BE with unlocked multiplier, but since you already bought 630, good luck with L3 unlocking
