Yep some of the top end P4 478 are soldered these 2 were pete, 1 took the chip off with it the other came off easily and both are dead lol, the water block i modded is working like a beauty , other stuff im havin more trouble than horis lindum with it, wondering if what you said the other day about the bios could be an issue pete

just delidded another 3 gig pentium 4, SL7PM, same as the one with the chip that came off with the ihs plate, temps b4 delid were 31 c idle, now delidded temps are 45c so i dont get it, seems pentium4's i delid like the IHS plate on , both on the same volts @1.53, clrd cmos and bios temp is 36c idle @1.32-4c v stock, so seems to me the delidding aspect doesnt work om all cpus , water temp is 5c in the res and 14c with the probe on the water block with both tests

Interesting thread, I have a lot of 478 chips here so might have a go at delidding my garbage chips in the name of science and make a list of those that are soldered and those which aren't

i dont understand the temp rises tho lewis, i wouldve thought theyd be reduced and the same increase has happened on 3 delids from the 3.0 gig P4's

Depends on the type of chip Shane. Some need the increased surface area to dissipate the heat. The dual core Opty's don't like being delidded either. PIII Tualatins also. Those plus yours all have done that to me. After I tested those out I just cleaned them up, put new TIM back on and glued the lid back on. THEN, I actually lost a few degrees. On the dual cores the individual core temps evened out also.

well im actually cleaning one up now scotty to try that, just melted the left over solder off the ihs plate but i thought the distance from the chip to the ihs plate would still be lower with tim as the solder layer was quite thick, i reckon the solder was close to a 0.10 thou layer thick and i was thinkin to wet and dry the bottom if the ihs plate where the ridge is to make it a few thou thinner to get a better squeeze on the tim on the chip and the reuse a thin layer of sealant and it would would seal once the ihs plate its the chip, just wipe off excess sealant that squeezes out of the sides of the ihs plate ...thoughts ?

Tim it thick. I clean off all the old sealant and use just a dot of super glue on each corner to hold the lid on.

I need some help guys ! Obviously not me but an oldschool lover homie and I think if we could find any answer it could be here. The info what we need is any board type what can handle cpus with Em64t instruction. Some E0 Prescotts was came with those. Maybe there will be somebody who have any infos about this. We know about an Ecs board where is written officially that 64 bit instructions problem solved and a few "hybrid" 945 chipsetted, ddr2 one but it will be awesome to find any type which is suitable and not super rare real s478 type. Thanks for advance, any info could be useful !

Interesting something I have never thought about. I dont know of any boards I actually thought all 478 were 32 bit

ECS i865PE-A (version 2.0) Asrock P4i945GC
are the only two non-OEM boards that I know of that naturally support 64bit on 478.

Be hard to find the CPUs the boards would be easier.

Be hard to find the CPUs the boards would be easier. More common than you think. Join CPU World forum just for the classifieds. I get most of my processors there. Dirt cheap usually too.

Dirt cheap usually too. 100% correct . Definitely a place to check into if you havent yet. Now I gotta look through my tons 478 cpus But it looks like there were only 2 skus made

Thank You ! Sent the info to the guy ! That Asus board could be the grail if has better feautres, better bios than the others. And if not super-rare ofc.

I've got one of these 64-bit CPUs and I've got several boards including G31-M4. If I don't forget, I'll have a look after my visit to Tokio (in a week).

Has anyone given them a go on Cinebench etc? I'm very curious to see how the old CPUs perform on a benchmark that has both 32 and 64bit capabilities to compare

What is much more interesting is that "IBM's" Pentium 4 3.2/3.4 (SL7Q8, SL7QB) are not the only ones s478 EMT64
P.S. back from Tokio, so will try to make some fun with these.
