OK, here is what I recently found about DDR2 667

Basically, HP should have equipted 667 in some configuration of V3000 or DV2000 model. The DV2174CL has 512M(x2 maybe) 667 from this link. You can also found 667 RAM part number from mantiance manual where I digged it out. HP charge it for $230

But these part numbers are not specified in z series, the only possibility goes dv2000 CTO without mention T or Z.

And also a good news, the AMD MK-36 is actually in HP DV2000's parts list. The part number is 438210-001. But it says 2.0 GHz with 256KB L2 cache, which is different from other site 512KB. The name is confusing. Other site name it Turion MK-36, HP name as Sempron MK-36.

 

AMD says the MK-36 is a 31W, 512KB cache, 2GHz Turion:

I guess they needed a cheap singlecore Socket S1 part that wasn't a Sempron?

 

ACER talk about the same thing. The only different from Sempron is clock rate and virtualization.

 

That is an odd part. Especially the naming scheme. According to AMD the last letter in the processor model indicates the relative mobility. 'A' would be the least mobile and 'Z' would be the most mobile part. So, in that sense the MK is less mobile than a ML/MT even though it has a lower TDP than the ML Turions.

If they wanted to bring out a single core Turion, the least they could do is provide 1MB cache, just to differentiate enough from the Semprons.

 

I guess they meant "Mind-Killer".
The code name is Richmond form wiki.

The cache and TDP are confusing with Semprons, especially 3500+. The Sempron's TDP is said to be 25W. If others are the same, I really don't see an advantage of this MK-36 except virtualization feature.

AMD really spend too little money on its marketing education. Users always hesitated to buy new AMD just because they don't know it. Even fans don't get anything from anywhere.
