Dual core coming next quarter as well... MSRP@$417.... This may put a hurt on X2 3800 sales.

Gentelmen these are socket 940 chips. Good luck finding a mobo which overclocks to you desires in socket 940 form. Not to mention it requires new motherboard and higher priced ones which 940 boards are. AMD has already said they will be DOUBLEING the 939 variants price. They are smarter than than you're giving them credit for.

How do you know? No-one so far confirmed it doesn't need ECC. Even AMD representatives were unable to tell me.OC Detective said:

Given that Sun is using them in their machines with non-ECC, unbuffered RAM, I think it's fairly safe to say that they don't require such options. In any case, they're almost certainly just rebadged A64 CPUs, so they should perform and overclock exactly the same. There's not much point in getting one unless, of course, you can pick one up for less than the A64 variant (and I would be surprised if you could do so).

Petr, I should have clarified it doesnt need registered ECC memory sorry about the semantics. It requires ECC unbuffered.Petr said:
This kind of puts a limitation on those wanting to try it out as although ECC unbuffered exists it is not typically what most users have right now. I guess this would be better suited to those making a complete transition from say older socket A (who need new memory anyway) than those already on A64s. Examples can be found here

I have to admit this perhaps places a limitation on the overclocking potential of these cpus and perhaps they are not the bargains that I thought they may be.

found an old review of some socket 940 boards on anadtech. They were reviewed for the FX-51 i think. Dont know if they will work with ecc ?

Well based on Emboss's comment perhaps they dont need ECC after all so that would certainly put them back in the desirable category!
Edit confirmation of the good news.
here is the AMD link referring to this new cpu on socket 939 and specifically how well they run on a Sun Ultra 20
http://www.amd.com/us-en/Corporate/VirtualPressRoom/0,,51_104_543~100324,00.html
(Beer Hunter note there is NO doubling of price!)
and here is the Sun spec which confirms you can use non ECC unbuffered
http://www.sun.com/desktop/workstation/ultra20/specifications.jsp#Processor
Perhaps this is merely a function of a bios update on socket 939s to allow both ECC AND non ECC unbuffered.
EDIT EDIT
Just checked the revision guide for AMD processors and the revision for these socket 939 Opterons is SH-E4 - exactly the same as San Diegos - so I guess its a case of waiting for them to go into stock.

Your name "OC Detective" is well deserved.
With your above two links from AMD and SUN, and this link

I would tend to agree that it is correct to expect that the Opteron 100 can work with non-ECC unbuffered memory and 939 board (non SMP) and the 100 is equivalent to an SH-E6 (00020F71h) which is the 1MB L2 A64 SanDiego and SanDiego based FX.
Further, corollary,
Ref: http://www.amd.com/us-en/Corporate/VirtualPressRoom/0,,51_104_543~100324,00.htmlAMD (Aug 02 said:
I would say the dual core Opterons 165 (rated 1.8 GHz), 170 (rated 2.0 GHz) and 175 (rated 2.2 GHz) would be equivalent to the JH-E6 (00020F32h) which is basically the 2 x 1MB L2 A64 X2 Toledo's.
The lowest rating Opteron 165 (1.8 GHz), priced at $417 per 1000-unit, ... having 2 x 1MB L2, would work with non-ECC unbuffered memory with a 939 motherboard (non SMP). It may be what many people (price/performance) are waiting for.
Don't know how much would be the unit price, but that is close enough to the current 2.0 GHz 3800+ Manchester X2 with 2 x 512KB L2 priced at around $350.

If it didnt require eec than i coulda bought one at this moment to try it out :/ but since it does i cant aquire enough money for some eec memory. but i cant afford the extra $150 for 1gb of eec ... i coulda afforded the cpu but not the memory

wait im confused... so it would work with the unbuffered memory on a 939 board. I will buy this if it would maybe. Im getting a DFI nf4 ultra-d and i was going to get a venice 3000 but if this would work i would jump in on it or at least try it... I suppose i could always ebay it if it didnt work.

Yes they will on 939 variants. This is a non-starter with $130 3000's, $240 3700's and $350 3800's IMO. There will be no such thing as a 144 for $125 in 939 socket.
"AMD yesterday raised the prices of its Opteron 1xx series by up to 91.6 per cent, saying the hikes were justified by the addition of support for cheap unbuffered ECC memory to the chips."

Did you read that article?
BTW don't Opterons have full multipliers control too?
The fact is that the chips we are interested are priced in a way where you'll be able to get more cache for about the same amount of money. Thats an easy decision to make as long as they clock well.

Gnerma no they dont have full multiplier control - they are locked.
Smesx1, according to the Sun documentation for its 939 workstation unbuffered NON ECC can be used up to 1 Gigs worth, as opposed to 4 Gig for ECC.
I suspect this is merely a function of a bios update for compatibility with non ecc.
BeerHunter, if you had read the official AMD link where they clearly state the Opteron prices, including the so called mythical 144 and read my first post where I mention low end bargains you will understand where I am coming from. The link you gave merely re-inforces what I said.
Even if the 144 was not to be available the 146 at $183 with twice the cache is still better value than a venice 3200+ or a San Diego 3700+ for the budget conscious (if it had the same overclockability of course! - hence my comment about it being for the adventurous).
This is in no way a bargain at high end, though the Opteron 252 is at a price comparable to the FX55, and my thread made no reference to such.

well im not sure,,, i want to order tonight so it gets processed. I have 2gb of memory now and i want to make full use of it. I think im just going to do venice and if this turns out ok then i might do it in a week or two. I just cant afford to be a guine pig right now.
What is interesting about the 1xx Opteron is that AMD is making available the "exact" same core of SanDiego and Toledo for Opteron in the lower frequency rating of 1.8 GHz and 2.0 GHz, hence costing much less to own these 1MB L2 CPU's.
The Opteron 2xx and 4xx which have coherent HT links for use in 2 and 4+ way SMP are still priced at high premium.
Implication:
I wonder whether (eventually) the SanDiego and Toledo would be made available directly as SanDiego 1.8 GHz, 2.0 GHz and Toledo 1.8GHz, 2.0 GHz at a (much) lower price than the current SanDiego 3700+ and Toledo 4400+.

The San Diego would then be marketed as 3000+/3200+ because it's only 'San Diego' to a few percent of us -- it's Athlon 64 = Athlon 64 to 9x% of the market.
So the only reason for that would be abundance of SD cores / lack of Venice cores?
As of now, there won't be anything below a 2.2 GHz Toledo until at least the end of the year holiday season and that raises the question of whether that's too close to Socket M2 to justify releasing lower end Toledo to a market that's covered by Manchester's.
There is a spot for the 4000+ X2 Toledo at 2.0 GHz though, maybe that would happen just before the M2 switch?

I understand socket 940 chips are cheap.. LMK when you find a 939 OSA144DAA5BN for $125... It will be $250.
BTW it's not mythical select 939 http://www.amdcompare.com/us-en/opteron/Default.aspx
and all 939 opterons will show. I don't care what AMD says price will be. They doubled 150/152 prices because they don't want to sell 939 chips for half price of FX's and 4000's. This is an obvious typo since their not going to sell more cache chips for less than 3000s at same speed. 225? maybe.
