Here's something a little different - A64 x2 AD*V*4400DAA6CD

[s7e9h3n]

Got this cpu a few days ago (and NO, you won't find this cpu in retail yet ). Here's the vital info:

AMD Athlon 64 X2
ADV4400DAA6CD
ACBWE 0534VPMW

This is the first time I've ever seen the "V" -as opposed to the normal "A" - marking on a A64. I'll have pics of the cpu and screens probably later on this week as I've been quite busy with other things of late........

Edit: Here's the pic of it I took the other day while it was still mounted under the insulation. Sorry about the poor quality. Not using my normal camera :

[freecableguy]

spread it on!

[Absolute_0]

So is this the new stepping for X2s? keep us informed about how they are clocking .

[Repoman]

Yeah definetly keep us informed.. I've been thinking about making the switch back to X2, even though I don't need it

[Okda]

waiting for more info and pic

[eva2000]

nice you and your no retailing cpus

[Supertim0r]

interesting ! waiting pics and results

Got the same question, and a partial reply. In this Post a guy mention six OPNs of unknow Processors (The ones with BX surfix are pretty identificable because we know that surfix from Semprons, but the other ones are not). If you search for those OPNs in Google, almost all of them will take you to Motherboard manufacturers Web Sites with BIOS upgrades and in they description they include those six OPNs, and some of them also includes the ADV4400DAA6CD that we are talking about (That is how I finded it by the way). No idea what the ADV prefix means and that is what we should investigate about. Usually, in both Opterons and Mobile Athlons XP/64 the diferent prefix should mean a diferent power consumption category, so the Athlon 64 X2 4400+ that if I remember correctly falls in the "Up to 110 Watts" power consumption category (Not that it consumes 110 Watts!), the one with the ADV prefix in the OPN maybe is rated for less (...But with the same Voltage? Impossible, because at that Frecuency, it would still consume the same Amperage). Other than that, can't make sense of it.

I know that "one result" from a Google search as well. It's odd that the site is the only one around which lists the forthcoming OPN's in AMD's lineup. I'm wondering where they get their info from

I'll get a pic and some screenshots up after I take this 3200+ Venice off my autocascade. I'm just testing a few things on it so it shouldn't be long until I get that 4400 in

[s7e9h3n]

OK,
I finally got this baby booted and funny thing is, I think I have a bad mount I had to boot up at around -48C since the temps weren't bottoming out like they did earlier today. When I ddi boot, the evap temps remained the same (in fact, they dropped a couple of degrees). HOWEVER, even with this bad mount, this cpu has either little or no heat output at all. Here's the first screenshot of this cpu. There are a couple of things to note while looking at the various ID progs. First is MBM's core temperature reading of -35C with bad mount and all. Second is Everest's core voltage rating of 1.1 -1.4V. I don't recall what my other X2' variable vcores were, but I'm pretty sure none were as low as this one. As I'm typing right now, I'm seeing mbm5's cpu temps @ -37C


I'll try booting @ 1.1V and will try to gather some more info soon.......

[s7e9h3n]

1.1Vcore bootup was without a hitch or any kind of stall whatsoever:



Windows is acting normal and no signs of instability atm.......

[njkid32]

Ok let see how low it can go

[Onepagebook]

I think you probably need to sit in laundary room and bench all night

my 4600+ seems has 1.24 for defauly voltage reading as well, but once they run the pcmark04 or 05, you will know,



OPB pc3500 level II? 2-2-2-5?

[zir_blazer]

Fab51 OPN Guide changed things a bit... In K8 OPN, the A letter for Voltage and Maximum Case Temperature means just "Variable". It doesn't even identificates a valid range. If you check AMD Compare, you will see that both ADA4800DAA6CD and OSA180DAA6CD got a "Variable" Voltage but in diferent ranges, 1.35V-1.40V for the first one and 1.30V-1.35V for the second one.
That means that even if ADV4400DAA6CD got the same letter that identifies Voltage, it default specifications shouldn't necessarily include the same Voltage range. So it seems that its more that possible that ADV is for another diferent Power Consumption category. If they work with lower default Voltage, is more than probable that they are higher quality Cores (Like the ones of the old Mobile Athlon XP were). I would keep an open eye on that one.

AMD Athlon 64 X2
ADV4400DAA6CD
ACBWE 0534VPMW

what is that 6 for, does that mean 1mb x 2?

[Supertim0r]

how can you get all those nice cpu ?

Ummm, you're talking about the "A" which follows the "D" in the OPN of the cpu. That marking is quite common. What's unusual about this cpu is the fact that it is not an ADA4400xxxxxx, but rather an ADV4400xxxxxx

Well, that's what I did with the 4600+ before I sent it to you That 4600 still is the best X2 I've ever seen, but this one's not bad at all.........

I got some benches in tonight and this cpu's been pretty impressive. I really didn't want to sit through 5+ 32M's so I just ran 1M and 8M @ each speed. Now I want you guys to observe the spi times of each core and see what happens as we raise the htt.......Note: Core 0 is always on the left and Core 1 is always on the right:

Here's where I started - Default speed (11x200) @ 1.1Vcore :





11x225 @ Default Vcore





11x236 @ Default Vcore






11x246 @ Default Vcore





11x255 @ Default Vcore


Ok up to this point, I had basically used clockgen to go from 225htt ->255htt. Therefore, my Vcore and Vram were still the same as when I started. I got an error on 8m @ 255htt, so I tried to bump to Vram to get 8m to pass @ Default vcore. It still wasn't possible, so I had to go a little higher on the Vcore. And NO, my ram doesn't need 3.4V to run @ 255Mhz It's capable of that @ probably 3.0V. I was just too lazy to change it:

11x255 @ 1.328Vcore 8m


So notice anything odd about the times as the htt went up? I'll do some more testing tomorrow. I'm getting tired of staring @ spi's on the screen

Yup

Seems that you didn't understanded what I tried to say (When I will fully learn english by once and for all?!). What I sayed in my second Post was rectifying this part of my first Post:

(...But with the same Voltage? Impossible, because at that Frecuency, it would still consume the same Amperage)

Later I finded than the "A" letter that identifies Voltage isn't neither a fixed value (For example, 1.5V) neither a fixed range (For example, 1.4V-1.6V), then give the example of the ADA4800DAA6CD and OSA180DAA6CD where both got the same "A" letter for Voltage but with a diferent value. What I am sure about, is that I never sayed than the ADV isn't rare

[don_vercetti]

that's pretty sweet, 2.8ghz with 1.32v is awesome! Looks like they did something right with these new cores.

[i found nemo]

then what is the number for 512kb x 2?

[s7e9h3n]

then what is the number for 512kb x 2?

5

Now things have reached a bit of a stall here....I think signs of the coldbug are appearing @ 255+Mhz on the memory. I've had some serious problems running any speed with my memory >255. I've done a couple of runs @ 3.1G+ @ 1.5V, but I had to use a divider and the memory was way below 250Mhz. I'm trying to see what I can do about it and will post some more results later......

[s7e9h3n]

Well, I tried to combat the cold-bug by installing a cold-plate which theoretically should have lowered cpu temps. Instead, the cpu temps actually improved and holding temps did as well The cpu's run into a serious cold-bug @ around -32C core. The only way I was able to make the following runs was to use a memory divider:






I think it's possible to get the cpu to at least make a screenshot if not run a spi @ 3.3-3.4G, but it would require a large amount of vcore which I'm not willing to try on this particular cpu

[s7e9h3n]

I've added a pic of the cpu in the first post
