I can't tell you now about the batch, but this is the AACYC mask and it is 23 week 2009.
That sample is slightly better overclocker than standard cacheless Propus core.
It is LinX stable with VCORE @1.488V and NB Voltage @1.34V

I would think that these would overclock to higher clocks if you got the cacheless core: The deneb ones are out of a really low bin and the propus-cored examples are the highest bin for their die. The only way I can think that that wouldn't be true is if the propus dies are tuned slightly different than the denebs, which may or may not be true. The propus chips also generally tend to be later production batches and would benefit from 10 or so additional weeks of process tuning at AMD.
A deneb running at 3.6 would definately be faster than a propus at 3.7-3.8 though, so I doubt the propus chips could compete with the deneb ones, higher clocks and all.
Most of Propus cores clocks lower than Deneb based. I did find no one Propus X4 whose can be LinX stable @3.7 or even at 3.8 GHz. Most of them clocks stable @3.6 GHz just like this sample.
Cacheless core has lower performance transistors, slightly different tuned process than core with L3 cache.

I bet those propus are manufactured in a similar fashion to the older deneb cores then. I have a 940 (2008 week 50) that behaves exactly like the deneb shown in this thread regarding voltage requirements and power draw, and a 920 (2008 week 49) that requires even more voltage for those same clocks. Power draw is suprisingly low though (1.5vcore for 3.5 on the 920 results in 135W draw, the 940 needs 1.46V for 3.6 and draws 141W)
I have a new 965 (2009 week 35) that will prime away at 3.8 on stock volts (1.41V), yet it sucks down 201W doing that. Kind of scary on the GD70's 4 phase PWM. I guess the new "high performance" transistors really wouldn't work well on those athlons, which are aimed more at running cool and sipping power than overclocking.

I've got no strings to hold me down.
To make me fret, or make me frown.
I had strings but now I'm free.
There are no strings on me
That's good to hear, I don't want to wake up to a roasted chip and board tomorrow morning.![]()
