Where are the other -J processors?

Anandtech says that Intel has release all processors with the -J suffix, from 520 to 570. But all I can find are the 560J and the 570J, so my question is, where are the rest?

Not all are available in boxed retail packaging yet. Dell and other places have been selling the slower J models for months.

Notice how the only new J models are retail boxed and not bare OEM CPUs?

Unfortunately Dell offering them for sale in systems is useless to most enthusiasts. I've been looking for a 550J for what seems like forever.

I'll have my 550J in a couple of days... from a Dell SC420 server. :p It's not Dell's fault Intel is shipping these to OEMs only.

Besides Linux, there's no final 64-bit OSs out yet. And AMD64 Linux is horrible right now. I went through that mess with my Athlon 64. The 6 versions of 4 64-bit distributions I tried were horrible. I had no (major) problems with the 32-bit versions of the same distros. I don't want to stray off topic too much, but the special builds for the emachines 68xx laptops seem to be the only decent 64-bit AMD64 Linux available.

Just to clarify, the 'J' P4's don't have EM64T (64-bit extensions). The 'J' just indicates an E0 stepping with Execute Disable Bit (EDB) support and Thermal Monitoring 2 (TM2).
 
I'm not sure if mine is a J, but it is an E-0 and it is stable with only 1.36 vcore. Idles at 40c with a gigabyte 3d cooler and very little to no thermal grease. I must say i'm shocked at the results, I think intel did great with these chips.

If you have an E0 you have a 'J'. That's all the 'J' indicates.

Good to hear something positive about the E0 stepping, what speed P4 is it?
 
thanks for clearing that up!


now, I plan on going dual-core when they come out and have matured. should I just go lga775 now, or s478? either way i'd be using AGP and DDR (not DDR2), so it just comes down to the socket and the mobo.

are all prescotts now e0 stepping when bought OEM, from places like newegg?

also, i plan on watercooling, and it would be nice to keep the waterblock from one system to the other, but not mandatory. I get mixed results when I ask which platform o/c's better...

It's a 3.8 570J, ES. My board currently doesn't support the 570 which is 200x19 stock. Luckily since I have an ES, I could use 14-18 and go around it, otherwise it wouldn't boot.

If you want to save your video card and memory, but wan't to go lga775, get the Lanparty 875p-T. There are other lga775 agp and ddr boards, but I couldn't find any on the 875p chipset. I have an agp 6800GT and the pci-e equivilent is way more expensive and harder to find, and I don't have the cash to buy new memory either. So I just got this board, and imo the 875 is still the fastest chipset.

I have an E0 that's not a J. The J indicates NX and other enhancements *are enabled* for both Celerons and P4s, plus EM64T for just the P4. The E0s that don't support either NX or EM64T don't have a J suffix (i.e. 550, 560, 570... http://processorfinder.intel.com/sc...cFam=483&PkgType=ALL&SysBusSpd=ALL&CorSpd=ALL <-- non J E0 processor).

explained: http://www.intel.com/products/desktop/processors/pentium4/index.htm
The letter J indicates a processor has Execute Disable Bit capability. Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting operating system. Check with your PC manufacturer on whether your system delivers Execute Disable Bit functionality.

And another page expands on that:
Execute Disable Bit
Execute Disable Bit allows the processor to classify areas in memory by where application code can execute and where it cannot. (This feature only available on processors with the "J" designator after the series, i.e. "560J")

Enhance Halt State
Enhance Halt State is activated when the Halt instruction is executed by the processor. Halt is executed when the OS goes into idle mode which lowers frequency and voltage (Dynamic VID) to reduce power consumption. (This feature only available on processors with the "J" designator after the series, i.e. "560J")

Intel® Thermal Monitor 2
An enhanced version of Intel® Thermal Monitor that lowers frequency and voltage, Dynamic Voltage Identification (Dynamic VID), to reduce power consumption. (This feature only available on processors with the "J" designator after the series, i.e. "560J")

pxc - All boxed LGA775 E0 P4's are indicated with a 'J'. The three technologies you listed - EDB, Enhanced Halt State, and TM2 - are new with the E0 stepping. The 'J' indicates this. There is no such thing as an LGA775 E0 P4 that doesn't support these features.

The only way you have an E0 that isn't a 'J' is if you have a socket 478 P4.

The 'J' DOES NOT INDICATE EM64T. The 5xxJ P4's DO NOT HAVE EM64T. This is fact. Anyone with a 560J or 570J can verify this.

The link you posted to the CPU in the Processor Spec Finder actually disproves what you are trying to say, it is in fact an E0 560J. Notice the box order code, BX80547PG3600EJ, the J at the end indicates an E0 stepping.

Edit - Here is that exact processor at Newegg. Notice it is a 560J, and the box order code listed matches that on the Processor Spec Finder page you posted.
