Phenom II X2 555 BE C3 Revision, where are they ?? :-)

The stock coolers can't be that bad, can they? (Well I suppose they can!)

Is there a "recommended" fan for Intel/AMD these days? Always more expense... *grumbles*.
 
the phenom quad stock coolers arnnt bad at all upto as high as 3.6 but they are a lot better than the ones pictured. they are noisey though :)
 
How much less power does it use in idle than the previous one exactly?

Anyway, people need to realise what TDP means, its the max power any chip off that wafer, or any wafer they push through to be sold under that name will use, lots, infact most/all will use quite a bit less power.

New steppings are largely just new classifications as yields go up and the worst chips improve, but not necessarily the best chips.

Meaning a old stepping one could well only use , call it 70W, while the new one you buy is the worst of the new ones and at 80W.

The chances are of course higher to get a better chip from the first batches of the new steppings compared to the new batches of the old stepping, but everything inbetween would be improving already and on its way down. Its likely that most of the batches for weeks/months on end before the reclassification are also basically 80W versions anyway.

The thing I'm trying to get across is without question do not just take for granted the numbers you see, from wattage output in reviews, to the assumption that every chip before this used significantly more power than a new one will, thats just not how it works.

When you test chips to get a rating it will be a case of them taking every single batch, for weeks, testing them all and rating them all as the very very worst core they come across, they may never have made another 550BE that was as bad.

AS the review said, it overclocked further on stock voltage........... but had a higher stock voltage. In other words, at the same voltage they overclocked about the same.

The CnQ improvements might obviously make a decent difference in idle consumption, though without comparison to the previous one its hard to tell by how much.
 
slightly different topic:
with the whole unlocking thing, would i be right in thinking that the new stepping would have a better chance of a successful unlock, as yields would have matured by now, forcing AMD to disable some perfectly good quads just to fill supply?
 
a couple of other places that dont have then in stock are saying 5th of feb. IMO there were only a few shipped to the UK when launched. By then it will have been about two weeks since launch, so i reckon another shipment will be arriving soon...

and with a current ~76% sucess on the C2s, if my theroy is right then booyah!

It says estimated release Q1 2010......

Still got another 8wks for them to deliver......

And even if a C3 goes beyond 3.8, its still not going to go much past 4Ghz on air, and i doubt you will notice any performance increase in games and apps with only an extra 200mhz.....

I can run my C2 550 @3.85 with 1.47vlts and keep temps under 55c at full burn test loadings with a cheapish aftermarket cooler, so i cant say a C3 550 would be any real advantage.

From what I see those seem to hit 4ghz easily and some go 4.2-4.4 with half decent cooling. This is actually a phenom II x4 965 with 2 cores disabled and reduced multi by 1.

Im happy with my 550 quad, but id like one of these when they hit the uk :-)

I'm not particularly excited about the Phenom II X2 555 BE, but AMD has sweetened the deal a bit. This chip now supports hardware C1E, like the first Athlon IIs. And no, I haven't encountered any CnQ bugs with it.

The hardware C1E means lower idle power consumption (I explained it in greater detail here) and it's courtesy of the new C3 Phenom II stepping. A side effect of this newer silicon rev is that it should overclock better. Our old Phenom II X2 550 BE hit 3.5 - 3.6GHz on air at stock voltage, and our new chip did 3.8GHz in the same conditions:

Part of the success of our chip here is due to its nearly 1.4V default voltage. Lower default voltages may only see 3.6GHz without going any further. Pushing beyond 3.8GHz proved to be very difficult on air, at least with any amount of stability under Windows 7 64-bit.

update latest version of CPUZ as i noticed one thing is you info on your CPU "Socket 939" as AM3 is Socket 938 -- i used II X4 965BE and showed AM3 Socket 938 (using Asus M4N82 Deluxe with latest BIOS version).
