Mobile A64 HSF question

[BlindBartimaeus]

Can someone give me an example of which heatsinks I would use with a TRUE mobile A64 as discussed in another thread? I would also need to know backplates whether or not which holes I need in my motherboard etc.

Thanks cause I really want to see 2.6 to 2.7 on a A64 and you guys hold the key.

The Cooler Master Hyper 6 is probably the best heatsink at the moment. The fan that comes with it is horrible though and if I remember correctly you can only use 80mm fans.

Does it need a back plate...what does it need to mount up to a mobile processor...this is the essence of the entire post.

I tried SLK948U and it worked with mounting kit that came with it (it includes backplate among other pieces)
You will have to remove CPU mount from mobo if it has any (was easy to do on mine)

Thank you, and will that work with a true mobile or are they the same as the DTR mobiles?

 

[dimasukr]

DTR and "true mobiles" A64 are the same from heatsink point of view.

I think this is the best heatsink Thermaltake Tower112

There is no such thing as a "true" mobile Athlon 64; they're both DTR CPUs, which are by definition, mobile

 

[BlindBartimaeus]

Well...if you look on newegg it looks like a .1 volt difference and one is called DTR and the other just says mobile...so...I don't know what to say. I would be willing to bet the TRUE mobiles or whatever you want to call them are Multiplier unlocked.

They're the same CPU, just with different labels. DTRs will run just fine at 1.4v

Yeah, but would it be as stable? Sure, both are 2Ghz 1MB L2 cache mobile parts, but because the 1.4v 'true" mobile part is designed with the slightly lower voltage it be logical to think it would be a slightly better overclocker.

NM. Just saw your post in another thread on thermal design. With the DTRs coming in at 81.5W @ 2.2Ghz, and the mobile rated 62W @ 2Ghz, your theory that they're the same chip but rebadged is plausible.

I'm very tempted to test your theory though

It's perfectly stable at 1.4v. I put it through 24 hours of Prime95 to make sure. It's the same chip no doubt about it.

What I really think happened was they found out that the DTR CG chips are fully stable at 1.4v and decided to create the illusion of a low power consumption chip by designating another model and capping it at 2Ghz. I'd be interested to hear results if you do purchase the CPU just for kicks though.

What happened is the same thing as happens any other time, all the cores are the same, but some are capable of reaching higher speeds / lower voltages, some are not. The mobiles are guaranteed to be able to run at 1.4v, the DTRs are not. That doesn't mean they are guaranteed not to, as your example shows. Same thing as with overclocking, really.
