AMD64 2800 w/1MB Cache (DTR) $100 Shipped, AMD64 3000 $108 Shipped (excaliberpc)

Somebody on some forum (Lilgator) has overclocked it to 2.4Ghz, with 300FSB.
You'll need a good MB for that.

What kind of RAM would you need to do an o/c like this?

These are DTR (desktop replacement or mobile) chips, that's why the ratings are different.
See here for a good discussion:

i'd be careful with those dtr processors. make sure your motherboard supports them before you get one

DEFINITELY listen to this. I've had a 3200DTR for a while now (since around July) and have ran into my fair share of problems. I got a Gigabyte K8N Neo Platinum and it severely undervoltages the CPU (even when you manually set the voltage to the max in the BIOS) upon bootup. I have to use ClockGen to modify the voltage to an actual level. HOWEVER, you have to be careful again! The values ClockGen tells you you're setting them to are INCORRECT and you have to monitor your changes with CPU-Z which displays the correct voltages.

All kinds of hassel, but a wonderful overclock. I got my 2.0GHz cpu running stable at 2.5GHz. 🙂

You would think...then again this thing does have 1MB cache, which factors into the rating sytem also.

AMD's rating system just keeps getting more and more confusing.
 
Important question - anybody know if these are multiplier locked? The DTR Athlon XP models aren't, so figured maybe these aren't either, that would make these even nicer.
 

From DTR discussion:

(d) The mobile CPUs lack the Integrated Heatspreader (IHS) common to the desktop processors. This allows better cooling of the CPUs as heatsink contact is directly with the CPU core itself. But as a result of this, the CPUs are "shorter" than their desktop counterparts and heatsink contact is a very real concern. Most backplates, whether included with the motherboard or the ones AMD includes with their retail chips will not work properly - the screw poles aren't deep enough. Only one heatsink setup works properly without modification with the mobile CPUs, the Thermalright SLK-948U Heatsink.
 
Are there any socket/wire tricks you can do to trick the bios into thinking it needs a higher voltage?

Multipliers are locked just like regular A64s - you can drop the multiplier but you cannot increase it. By default on my K8N NEO Platinum, my 3200 begins with a 9.0x multiplier even though it's supposed to be a 10.0x multiplier. I have no problem turning it back up to 10.0 though.

You've got me but even though my mobo seriously undervoltages it, it also significantly underclocks it (something like 800MHz or so). So it has enough voltage to boot up. You just need to make sure you have CPU-Z and ClockGen to fix it. I have saved ClockGen profiles so I just have to double-click on them after I boot up (I had issues putting them into the Startup folder).

Note for those who do get this and go the ClockGen route and try to overclock: Something you will learn relatively quickly is if you slowly overclock things you will get MUCH MUCH higher than if you find your peak, reboot, and jump to your peak immediately. You have to have ClockGen do it in increments and after every increment, drop the AGP bus back down to where it needs to be. Here is an example of my script:

[CG-NVNF3]
VID=1.450
FID=10.0
FSB=205
AGP=67
FSB=210
AGP=67
FSB=215
AGP=67

Notice that after EVERY FSB increase, I drop the AGP bus back to 67MHz. This one only goes to 2.15GHz. In order to get to 2.5GHz I have another profile I run after this one (it seemed to me that your profile scripts could only be so long in ClockGen).

This is also correct. Before you buy one of these, make sure your mobo/HSF combo will work with it. I have no problems using the SLK948 with mine on my K8N NEO Platinum.

Gygabyte doesn't make the Neo Platinum.
 
The 3000+ in my laptop hits 2.0GHz easily but is held back by no AGP\PCI lock, these chips are nice.

These aren't DTRs. These are 62w "Transportables." The volts are lower on these so they're actually significantly better. The only difference between a DTR and a desktop chip is the DTRs have the heatspreader removed.

That said, I wouldn't expect over 2.25-2.3GHz on either of them.

Board compatability can be a problem with the Transportables. They also only work with a few heatsinks - the best being the SLK-948u and the Swiftech MCX6400-V.

You can run any RAM - just use a divider.
 
sleepeeg3 is right, the part # they show is AMN2800BIX5AR, the AMN in the OPN indicates "Athlon 64 Mobile 62W." If it was a "Athlon 64 Mobile DTR" it would have been a AMA coded CPU. AMD code would have been a "Athlon 64 Mobile 35W."

AMN = Athlon 64 Mobile 62W
2800 = model #, 1.6 GHz
B = 754 pin Liddless OµPGA
I = 1.40V Operating Voltage
X = 95°C Case Temperature

(At least occording to the OPN Guide I used)

i'm not so sure about that. from what i've read, your motherboard bios needs to support it.
