I have a F model.... havn't been able to find any info on it - Got it about 2 months ago from ClubIT (or whatever they call themselves)

I can run it rock stable at 3.73 on my asus p4p800-e deluxe, but thats just using the motherboards "automatic nooby" overclocking. I'm really wanting to know if anyone else has gotten better overclocks and how, with what voltage, ect.
 
Standard Prescott with 64-bit enabled. 1MB cache, although I don't know if it has the XD-bit.

I believe that it does. It was an OEM CPU. Most of them were sold to Dell and companies like that.
 
heres the cpu-z pic... hope you can help me more - if so, can I run windows XP 64 bit? And also, what is the XD bit?

Yes, it fully supports EM64T. IOW, you are fine for XP64.

XD (Execute Disable)-bit, originally implemented by AMD under the name NX (No Execute) is a flag that programs put on blocks of memory to prevent over-writing them. It is designed to prevent, among other things, intentional buffer overruns, in an attempt to increase computer security. XP SP2 is required to utilize this.

Also, I thought the F-chips were available in retail as well, but for a very short time.

Pentium4-F referred mostly to socket775, but also existed in socket478. The 775 flavor basically became the 600 series, by the looks of it.
 
wow... this is pretty cool... I picked that sucker up for 219. What luck.

Besides running a 64 bit OS, what else will this do and what sort of games and applications will this benifit me? Or is this something that a gamer who just encodes a lot of DVD's won't appriciate very much?
 
If it really is a 3.4F, then it has 64-bit support. Don't always trust CPU-Z.

In order to utilize the 64 bit capability, you need to run XP64 or a 64-bit Linux distro. Most 64-bit programs run a fair bit faster than their 32-bit counterparts; for example, one of FarCry's patches enabled significantly greater field-of-vision and detail level, with absolutely zero performance hit. I can't find any benchmarks right now, but basically you'll only see benefits on 64-bit apps. 32-bit programs running on XP64 don't show any real improvement.
 
dunno what happened to the link to intel's site, but it said that some 478 were
 
I got a 640 3.2ghz which has 2mb cache which i oced it to 3.8ghz with my Gigabyte 8I915P Duo Pro i am pretty sure i can oc it higher but i running da stock hsf atm.

These have been out for months.
$415 - pentium 4 561
$269 - pentium 4 551
$162 - pentium 4 541
$173 - pentium 4 531
$139 - pentium 4 521

There were no Sc-478 versions. They run WinXP64 pretty good so the misformation can stop=P There are even Celerons with EM64T as well. Intel could have shown some class by just calling it x86/64.

Now why these weren't benchmarked I don't know. Come on [H]ardOCP? The 551 is the one I looked at before I made up my mind to build an AMD rig.

If you leave out, "on Desktop Computer" or Non-Server, then that makes what you're saying faulse. If I remember correctly, Intel's Server Chips have used NX bit long before AMD did.

XD (Execute Disable)-bit, originally implemented on the Desktop Computer by AMD.......

my head is spinning since there are so many conflicting views, and I remember a link that disappeared that said there were some socket 478's.

so I guess the only way to tell is to try to install win xp 64?
 
im pretty sure there arent any 64bit chips in s478... all the 5xx series chips were in LGA, so i dont know why you think its an -F... looks like a standard -E to me..

so what does the F in family mean? How would I make sure for sure? Would looking at the chip itself tell me?

CPU-Z is working perfectly. You do not have a 64bit processor=P If you did, it would say so on the "Instructions" line. It would show MMX, SSE, SSE2, SSE3, EM64T. F just might be for Sc-478 P4, hell, my old 2.6C is a F.

oh damn, i didnt know he was looking at 'Family' to get that he had a "3.4F"

yeah, thats nothing. you have a 3.4E.

No biggie bud! I read about a stripped down version of Win2K that never came out and I thought it had.
