MOBILE A64 PROCESSORS!

[Avalon]

I was just looking at newegg, and I came across this

http://www.newegg.com/app/ViewProduct.asp?catalog=343&DEPA=1&submit=property&mfrcode=0&propertycode=&propertycodevalue=6055

62w, 1.4v (Compared to 1.5v)
2800, 3000, and 3200+
The downside is that they run 200mhz slower than their desktop counterpart
But these seem like the real deal, and I think should work in a normal socket 754 environment...
All of them come with 1mb L2 cache...the 3200+ mobile runs at 2ghz on 1.4v...so imagine
Are we looking at something golden here?
Anyone seen this before?

 

[GeneralGrievous]

I guess they run at lower mhz due to higher cache....should give the same performance at a lower voltage. Now if there were some better A64 boards these might be good overclockers.

I was thinking about selling my medicore mobile 2600+ and getting a 35w mobile 2200+...but now I think I want to get a new mobo and one of these chips to try out...just the perfect excuse to upgrade to socket 754
But I'm still leaning right on the middle of the fence here...I can't decide if I should or not.

*Edit*
Erg...I had looked, and thought I didn't see any threads on this...guess I was wrong, while doublechecking
Sorry for the repost.

I wonder if these are multiplier unlocked? Like the other mobiles having all the multipliers unlocked? Boy if this is the case...plus the CG stepping....ohhhh

I think they would have to be to enable them to run at lower clockspeeds for saving power.

 

[Shortass]

Is the Mobile 2600+ worse than the 2200+? I don't understand...

 

[Avalon]

They'd have to be unlocked, because they also utilize Powernow!

 

[Celeryman]

Very interesting indeed. One of these may be my next cpu. Gonna have to save a little bit before I can buy one though :frown:

 

[BlindBartimaeus]

I am waiting for the first review saying they are and I am all over it.

Yeah neither do I... Isn't it only 35W as opposed to 45W because it's running at a lower speed and lower voltage? If you run them at the same speed and voltage they will probably running at the same wattage, no?

 

[BlindBartimaeus]

Yes you are correct on that. It is only lower due to speed and voltage.

 

[Avalon]

Well, that's true, but I was thinking about the mobiles I've overclocked. Typically, in the beginning you get a lot of clock speed gains over relatively small voltage boosts. The higher your voltage, the less clock speed you gain per boost. Eventually you're up in the 1.85v range and higher, and getting minimal gains per increasing voltage boost. This 2400+ mobile is already rated at 1.8ghz for 1.35v, not far from the 2500+ mobile at 1.86ghz w/1.45v. The 2400+ 1.45v mobile was rated for 1.8ghz, and that one was a very good overclocker as well. People were getting that to 2.4ghz easily, and I saw some at 2.7 and higher with non-air cooling. Theoretically, with only 1.35v, this 2400+ can do a noticeable ammount more than a higher voltage part.

If theory is right in an overclocking sense, then the current mobile 2600+ would be "worse" than these new low power 2400+ chips at overclocking.

Someone get one damnit!

whats the difference between the mobiles and the mobile DTR A64 ??????

There is no difference between the Mobile A64 and the Mobile DTR A64.

well good.
and the only thing I hope is that the exposed core on the DTR will fit under the base of my Danger Den S-TDX !

 

[Avalon]

If I remember correctly, there were two big steppings for the DTR chips...I think one was the C0. If someone could please fill the rest in. But one of them was a good overclocker, and the other wasn't. That's just what I heard. The DTR chips perform at normal desktop A64 clock speeds, with an 81w power output. The mobile chips do 63w(?) at the cost of 200mhz in clock speed, but at a lower voltage (1.4v I believe). Again, if any of this is wrong, feel free to correct me. I'm going by memory here

Hah...I have the specs listed in my first post in this thread...lol

AMD's documentation shows that they run at 1.4V so these seem to be, at best, well selected Athlon64 DTRs. Therefore, I would expect that the max mutliplier lock is still in effect. There are 1.2V Athlon64s coming but those are a different breed altogether.

http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/30430.pdf


Another point for those that think these are some big advance in thermals for the Athlon64. Remember that when AMD rates thermal output they only give the max output for the single top of the food chain CPU. Thus, for the C0 stepping, the highest is a 3400+ at 89W. For the CG stepping DTRs the highest is a 3400+ at 81.5W. Now here's where you need to pay attention. The highest AMN 1.4V CPU is the 3200+ and NOT the 3400+ so the TDP listed of 62W cannot be compared to the other CPUs. In fact, if you compare it to the DTR CPUs and do a little guestimation (don't know if there's a linear relationship between clockspeed and heat) you'll see that these are basically CG DTR CPUs running at 1.4V I really think these are just DTR CPUs that AMD has decided to rebrand.

For reference, my DTR 3200+ runs just fine at 1.4V

Bottom Line - Much ado about nothing. These are simply rebadged DTRs which have been available for a couple of months now.

 

[Bar81]

As to your other question regarding steppings. C0 is the older stepping and CG is the newer stepping. The 3200+ DTR is a CG stepping, the 3400+ DTR is C0. The Athlon 64 mobiles are all CG stepping. The desktop processors are C0 for the most part, but the newer ones have begun the transition to CG, you just have to look for the right markings. CG as a newer stepping has less thermal output, overclocks better, and has an improved memory controller over the C0 stepping. However, CG stepping CPUs are also tougher to get working right. Some mobos simply don't support the new stepping but should with new BIOS revisions. As always, do your research.

After reading http://www.x86-secret.com/popups/articleswindow.php?id=105 and seeing that A64 3500 doesn't run faster than A64 3400 but surely will cost much more
I want to buy one of these AMN3200 and overclock it to 3400 (should be easy).
Did anyone tried to put DTR Athlon into VNF3 ?
(Chaintech official reply was that they do not support DTR never tested it nor recommend on VNF3-250)

 

[Bar81]

I'll let you know. I just got one on special and it should be here Thurs.

 

[dimasukr]

Bar81,
Did you get the motherboard yet?

 

[aug1516]

I picked up one of these 2800+ Mobiles and threw it on my MSI K8T800 MB. It won't post with voltage on auto,had to specifiy 1.4v. This is with the latest bios so I guess MSI doesn't officially support these yet. The other thing I noticed is that without the heatspreader some heatsinks don't sit right, like the Zalman. Had to modify that a bit to get a good fit. Lastly these don't seem to support Cool N' Quiet because it stays at 1.6ghz no mater what, not like my old 3400+ that would run at 800mhz idle. I think I'll check out the processor driver, maybe that has reverted back to the Microsoft one or something.

** Edit: Tried replacing the driver and that did not work, went back to default driver. I don't think these Mobile chips support Cool N' Quiet**

Yup, no go; wouldn't even post with the DTR. The board is straight amateur hour (you can read about it in the other post in the mobo section). I will be sticking with my ASRock for the time being although I'll probably give the MSI a shot.

I know that instead of Cool n Quiet I got multiplier control for my DTR so it seems to be an issue across the board with the nondesktop CPUs.
