Answer:
Alright, the X2 550 C3 is NOT a Black Edition processor! The X2 555 C3 IS and replaces the X2 550 C2 BE. So now I just have to wait for a site to carry, or offer it special order, for me to get it :\

Scratch the motherboard debate... Just saw news on 890 chipset and I wanted to make this board somewhat futureproof against upgrades, and I don't want to risk the 6-core not being supported on the 790/750 setups I'm sure now the ***** thing will cost $50 more than the one I wanted, not to mention it probably won't come out for a few MONTHS more. Given that I'm looking to upgrade NOW and not later

I'm trying to make the jump (or rather, huge leap) to AM3 but don't want to set myself up for an upgradeless future, even though it'll probably be that way if the 6cores need run a new socket. Still, I'd at least like the ability to fill all 4 DIMMs with memory and be able to get at least 1333. With that said, I'm limited to C3, but I'm on a budget so that means I'm limited to X2/X3, but X3 is tossed out due to no C3 versions. I'm also a diehard overclocker so BE is the only way to go, knocking out the 545!

So here in lies my confusion! I've researched as much as I can't seem to find the answer, but the info on AMD's site is showing that the C3 550 is a BE but it's OPN is reflecting it's not, HDX vs HDZ... For anyone who hasn't ever looked at the product lists, the Additional Info section says "Black Edition", and all BE chips I've seen start with HDZ. Yet even the 955 shows HDX with only the 965 being HDZ, again this is in C3 flavor only as C2s adhere to the the usual rule of thumb.

I've emailed AMD, and the ticket they opened.... well lets just say I can't even log in to see what it says :\ The provided user name and password don't work, and I can't retrieve the password because either the username or password is wrong, and I can't register because my email is used -_- Emailed their more 'commercial' oriented department, haven't heard back.

And now for the bonus round! The X2 555 BE! Seen them for sale on European sites, but not on US ones. Not that that means anything since it was hard enough to find the C3 550 tray! Now the 555 is boxed, which is helpful for me since I don't know if my S939 heatsink will fit an AM3 or not (guess I could swap mounting brackets on the mobo), and the european sites show that it's a special order item which the 550 is showing as that also. SO! The question: Does anyone know of a site that take special order requests, but isn't an arm and a leg? (for comparison, the 550 C3 Tray I can get for $87). If it's too expensive I might as well just get the C2 X3 heh I'd love to just import it, but the shipping would be horrible, pair that with the price that I found being almost in 955 range anyways!

Thanks in advance!!
(The mobo I plan to get already shows support for 550 C3, 555 and even the X3 740 heh So that isn't of any concern)

I run the 550 in my backup comp, overclocked to 3.7GHz on Vista x86.
It was bought about four months ago when Newegg had it on sale for about $95.00

Curious myself, I just looked at CPU-Z, it reports:

Stepping: 2

Revision: RB-C2

Honestly, I didn't know that they released a C3 version of the 550.
If you can find it, buy it or better yet, wait to see if the 555 is released here.

If you get a 785 or 790 board with ACC, you may be able to unlock the extra two cores.

Good luck.....

Yep, planning on the Giga MA790GPT-UD3H. 790/750 equipped. And I was also surprised to see the 550 (and many others, like the 545) available as C3, when all you see for sale is the 955 and 965. I'm hoping the skip of X3 is not due to lots of fab problems leaving only 2 cores working, so I can get em all If anything I'd settle for an X3, or even a X2.5 (coining that now! lol) where the other 2 cores can only function with a really low multiplier But since it wasn't a die shrink I don't see a quad being too far fetched. I'm not aiming for that with my purchase though, I'm trying to save money while getting a good setup. I could just get an Athlon II if I wanted quad that bad.

Anyone have a pic of the stock heatsink that comes with BE CPUs? I can't find one anywhere heh

No pic here... but the HS I got with my 550(C2) is short, all aluminum, 70mm fan, Id say it's just good enough to run the chip out of the box, so If you plan to OC, unlock cores, want low fan noise under full loads, etc, etc, then just buy a decent cooler.

Best of luck on the unlocking and/or overclocking.

Ah, so it's the exact same critter that my 939 X2 is rocking heh It keeps it at 23c idle @ 2100mhz and about 28c @ 2800 (both 1.42v), which @2.8ghz it's TPD is estimated at over 100. Well above that of the 550BE! Kinda surprised that they didn't come with that nice heatpipped version the 4000+ came with :\

Sadly still no reply from AMD (or any luck logging in), or the retailer I contacted who I planned getting the 550 C3 from.

Stock fan is tiny. I used the H50 on the 550 and dropped temps by 10-12c. It would idle at 17c and max out at 30c (rare).

Yea it is small, I never even tried it, it looks like something you'd get with a 45W or 65W CPU.

A friend of mine has the 550 too, using the stock HS under load tests (@3.4GHz) the CPU temp was peeking at max rated temps and fan was spinning at max speed to keep up (noisy). He upgraded from a s939 4600+ (110W CPU) so I told him to try that 4600+ cooler on it and his CPU temps dropped 12C, + less fan noise

Yea I saw that H50 and would really love one, but since I'm pretty much on a $300 budget, I've got to make due with what my 939 has (since apparently that works according to Edgemeal). Had I the extra funds, I'd love to get the H50, a bigger PSU and a HD 5770 :\ Alas my x1950 Pro heavily OCed and my dual PSU mod will just have to suffice for now...

Edge: I presume that HSF your buddy used from his 4600 was that heatpipped model? I might know someone with that style laying around, and maybe I can get it off him for the cost of shipping *crosses fingers*. The fan that came on the stockers was pathetic though, that's for sure! heh I had 2 fans from my old Athlon SMP rig which came on the Volcano 7+ I had on them, and I'm using it on low to get those temps I mentioned. Even if it was in a case right now, I have the fan ducted outside with a fan pushing in to the ducting, so that'll at least help the temps as well.

Right now it's just a toss up between the motherboards... I sadly can't shop at NewEGG anymore due to being in a state where they charge sales tax (which is 9.5% here), but they have MIR on 2 boards I was looking at, plus I just got a $10 off promo code in my email from them, which offsets the tax. Anyone know which would be a better bet between the 2? They are basically the same exact boards, except the biggest difference being the 790X has 8+2 phase for the CPU vs the 4+1 on the 790GX, which I'm not sure exactly how much of an impact that'll impose on overclocking stability :\ THe pictures between both are a big confusing for me, since the 8+2 has 10 small chokes where the 4+1 has chokes that are about the size of 2 that the 8+2 uses. Makes me wonder, but I'm not all that knowledgeable with ICs NewEGG comparison of those two. (Shame the 790X doesn't have ATA133 like the GX, as I have quite a few PATA drives I still use, and only 1 PCI controller card)

Sadly still no reply back from either on the 550 being a BE or if the place I emailed can order 555s :\ Might have to give someone a call today...

Thanks for the info guys, and if anyone comes up with something (or has one of those nicer heatpipe stock HSFs they could part with ) lemmie know!!
