OK, first, read some of this link on AMD's site:
http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_861_9633^9616,00.html#74659

Then, I ask:
People go and buy mobile xp chips and then OC them massively cuz of their nice thermal ability and well, they are made better as it seems in general.

Someone told me that an XP-M goes at 133x11 fsb and non M goes 166x14 FSB.
I believe people OC them way above this, am I correct? And if so now what about the Athlon64?

I am looking at the athlon 64 3200+, the one thats 2.0 ghz and has 1MB L2 cache. I see that AMD has it under the DTR chip category.

Does this mean its the same chip with better cooling?
A slower FSB chip with better cooling?
The same darn thing with a better board that supports cool and quiet?
Something else that wouldnt be ever on par with a regular, desktop rated 754 slot 3200+ with 1MB L2 cache?

Pick one or something please! and whats the OClocking headroom on these badboys?

Peace

When the A64 dtr's first hit the shelf, a lot of people tried to OC them. The eary results were not too good. Most had done better with standard chips. There is also a problem with the msi nforce board not working with the dtrs.
Maybe, when the 90 nano chips become more available, the situation will change. Right now the best dies seem to be going to the low power opterons.

el_jefe_77 :

I think you mixed up some values about the Athlon XP-M 2500+ and its desktop counterpart, according to basic maths and CPU specs, the XP-M 2500+ is meant to run @ 133MHz x 14 (1867MHz) while the desktop 2500+ run @ 166MHz x 11 (1833MHz).

Unfortunately, XP desktop chips CPUs that were manufactured after week 39 of 2003 have their multiplier superlocked, therfore greatly reducing their OCing flexibility since the FSB is directly related to the mobo chipset and your RAM quality.

On the other hand, Mobiles are unlocked due to PowerNow! which enable them to throttle themselves according to the CPU load in order to save battery life and they need much less voltage than desktop CPUs in order to reach the same frequency due to their higher quality.

Fortunately, would be OCers can mod their desktop 2500+ and turn them into Mobiles as it is demonstrated <A HREF="http://www.ocworkbench.com/2004/guides/unlockwk43update/ocw_unlocking_xp39+.html" target="_new">Here</A>.

I think that the A64 CPUs are'nt mature enough to yeild the kind of extreme OCing that we're used to see with Mobile Bartons and P4 Northwoods.

Mobile Bartons can easely be OCed to 2.3GHz with or without any voltage bump and 2.5GHz is definetly possible on air, 2.6GHz and above will require more exotic cooling methods or one of those fabled "Golden Chips". Due to their low price compared to A64 and P4 CPUs, Mobile Bartons are an OCer wet dream, even if you manage to blow one up, another can be bought for a relatively low price, once the one I have die, I'll be looking for a Socket 939 solution anyway.



AXP-M 2500+ @ 2.5GHz 200MHz x 12
Abit NF7-S V2.0
3x 512MB of Samsung TCC4
Sapphire Radeon 9700 128MB @ 360/310
2x Maxtor 40GB 7200RPM RAID-0

ahhh see? yeah this guy too has noticed how the DTR versions are noticably cheaper.

Well, good to know that unlike mobile xp chips, the dtr a64's arent good for oc'ing.

However, I never want to oc my chip. not at all. not into that.
What I am into is running super cool and quiet systems. I know that if i bought an xp-m 2800 with a 7000 CU zalman fan, I can keep it at that speed and just keep one exhaust 120 mm fan on low for the case.

I wanted to know if DTR was AS FAST as a64 regular, because that normally means i can keep it cooler easier in a non-oc setup.

Ah, different story. The dtr A64s are clawhammer chips. They work as well as clawhammer A64s, are a little slower than the newcastle cores. Not much though, and they make good use of cool & quiet, so the do stay cool, unless you are gaming. Even then, they run cooler than the newcasle chips. A setting of about 1800rpm should be fine

hm. yeah well I would be gaming. I wonder how much cooler a DTR chip goes?

And, would it run the ram at the same speed?
Like, does it still work with pc4000 ?
