Semprons with Cool and Quiet

[Zap]

I just saw a Fry's ad that claims Cool and Quiet for a Sempron 2600+ s754. I've also seen an advertisement elsewhere stating a Sempron 64 2800+ as having Cool and Quiet. That got me thinking... always a dangerous thing... the collective forum wisdom states that Cool and Quiet is present in socket 754 Sempron CPUs at 3000+ and higher, minus the original .13 micron 3100+ which I've personally verified does NOT have Cool and Quiet. Everytime I've seen it mentioned, people just state it as fact.

Is it a fact?

I've tried looking on AMDs site but they don't seem to advertise this particular feature with Semprons. Let's make a verified list of Semprons, stating whether or not they have Cool and Quiet. I would consider verification to be multiple first hand experience with being able to manually lower multiplier (through BIOS or software).

Please post first hand experience on whether or not a particular Sempron has Cool and Quiet. If you have experience and the chip is not verified on the list, please post with your experiences.

Semprons will be grouped by speed rating and stepping. I've listed every processor that AMD lists with a part number. Yes, some of these I do not recall seeing "in the wild" but they are listed just in case someone comes across them in a Compaq or something. The 130nm chips are Paris core and the rest are Palermo (someone correct me if I'm wrong).

My Palermo Sempron 2800+ would not do Cool and Quiet.

Can you be a bit more specific? Which core does CPU-Z report?

D0, E3, E6

Is it 64 bit? If not, D0 for sure.

My D0 core Palermo Sempron 2800+ does not support cool n' quiet

Cool and quiet doesn't even work well with some boards. My new kv2-Lite ecs board won't recognize the software for it. For quiet, just use a zalman rpm adjuster for the cpu heatsink.

Would Cool?n?Quiet help w/overclocking a Sempron?

ie: i read an ARTICLE that a 754pin sempron 2600 (1.6ghz) can be o/c to 2.5ghz (50% more!).

"Cool?n?Quiet is disabled in the Sempron 2600+. As a consequence, the processor doesn?t permit to reduce its frequency multiplier. "

How would Cool?n?Quiet help w/overclocking a Sempron?

edit:
Wikipedia says 754pin sempron3000 or better has coolnquiet?!

edit2:
Tomshardware says that too
