Oh you thought Prescott would work on your 865PE/75P mobos? (http://www.anandtech.com/news/shownews.html?i=20014)

Think again. Seems like they most likely will not. So if you're planning on upgrading to the Prescott by buying a Springdale/Canterwood motherboard now, you better think again. Just a little heads up.

BTW, Intel must be making a lot of people mad with their socket and voltage regulation changes. Seems like there's never a real long upgrade path with any of these platforms.:rolleyes:

Yeah, I didn't see this one coming. I figured they keep µPGA478 solid up until Socket T comes along, but they did the same thing with PGA370 when the Tualatin core came.

I don't know if the case is that the core shrink means that the current voltages are too high for the silicon substrate to handle and a redesign of the power system is needed to keep the longevity of the Prescott core to a maximum. I doubt they would do a change like this to screw people out of their money...

But there are mobos out there that have voltages down to .875V or something down there, so voltages shouldn't really be a problem, unless you mean some other voltage.:confused:

I believe they were talking about a bus voltage change, and possibly other signal voltages also being reduced.

I know there is at least one Asus motherboard that claims Prescott support. The question is if they thought Prescott would basically be a P4 revision update only or if they have designed the power supply to conform with the Prescott needs also. Details are sketchy to say the least...I know Asus has claimed support for other motherboard features that haven't materialized.

I though that the main reason for many mobos having a max vcore of 1.6v was due to the new power requirements of Presscot. That's what they told us at least... :rolleyes:

intel is prolly making more $ off the boards then they are the cpus :rolleyes:

the days of 1 moboard lasting many CPUs is gone.
now are the days when 1 cpu will last many motherboards ;)

I too agree. Seems that chipset market is becoming an extrememly profitable one... ;)

Yes, unfortunately that seems to be the case currently. When Socket T comes, at least Prescott and Tejas will be supported. That's the big problem as die-shrinks continue, voltage becomes more and more important, since resistance increases between die-shrinks matter so much more at 90nm and below.

Update
According to this (http://www.overclockers.com/tips00424/) some 865/875 boards could support presscot. However as u can read here (http://www.xbitlabs.com/news/mainboards/display/20030712011416.html) most boards available now won't be able to support it.
Asus is claiming that P4P800 (and maybe P4C800? :?: ) will support presscot. The story just began... ;)

I would be more intersted in whether the 865/875 chipset will support DDRII.

But with this comment,

Thugsrook:

"intel is prolly making more $ off the boards then they are the cpus

Intel would only be shooting themselves in the foot by releasing the Prescott if the 865/875 supports DDRII.

The average budget minded overclocker wants better memory, not a new CPU.

Isn't DDR-II a whole different pin count/interface?:confused:

Fossil

07-13-2003, 07:06 AM

yes you are right Chuck.

"DDR-II will use 232-pin modules as opposed to DDR which are 184-pin modules. We can expect to see the first DDR-II memory running at speeds of 200/266MHz (400/533MHz DDR) using the standard 64-bit parallel bus for a bandwidth of 3.2/4.3GB/sec. With 333MHz (667MHz DDR) for 5.4GB/sec. Dual-channel DDR memory on motherboards will make up to 10.8GB/sec bandwidth for example."

My point is that memory is the bottleneck in the PIV C processors we have today. I don't want a new processor, I want 600 DDR or something in a DDRII flavour that can max out todays processors.

Grantsdale will be the first Intel DDR-II chipset. Launches in Q2 2004 using the Socket T interface. Dual channel DDR-II, by the way.

Chuck232

07-13-2003, 04:43 PM

I thought it launched Q1...:confused:

I'd like to see Intel push to get at least DDR-II533 modules out by then since that's what Grantsdale can use...

http://www.theinquirer.net/?article=10367

"Intel also confirmed details of the Grantsdale chipsets being introduced in the second quarter of 2004. Those will include DDR2, a PCI Express X16 connector, a "third generation" integrated graphics core – probably licensed from ATI, a PCI Express X1 connector and more, four, S-ATA ports, as we expected"

The graphics core refers to the Grantsdale-G.

Hehe... ASUS has now removed the Prescott compatibility from its P4P800 and P4C800 pages now. Guess that means buying them won't get you very far if you're planning to upgrade.

But yet the old P4C800 DLX stills supports the new proc: http://usa.asus.com/prog/spec.asp?m=P4C800%20Deluxe&langs=09

Lol... there seems to be some weirdness..

Oh, cool. So the USA site claim Prescott and the other sites don't. :rolleyes: Does that mean that all USA boards will support the proc? :p :D

Doing a search for prescott under motherboards gets compatability for these:

I don't think Intel or anyone else has a clue. :rolleyes:

Freaking Intel - bah! Guess I stick with my AMD board for now :rolleyes:

Chuck232

07-17-2003, 02:57 PM

lol @ XJ...

But then again, if you bought an AMD board now, how far would you have to go?

XJ.

07-17-2003, 03:02 PM

I just bought one last week (an amd sys). I wasn't real happy about the setup and thought about returning it and going to Intel since the current chipsets were supposed to support Prescott. I thought that would make up for the extra expense of an Intel system by getting more life out of it. No so it seems. Oh well...

07-17-2003, 03:12 PM

XJ, which amd sys did you get?

XP2500+, NF7-S IIRC...

Well it appears that the jury is still out on my P4 board-it might or it might not support the Prescott. I'm not sure yet. :confused:

Bingo! It's not a bad system, by any means. Really, it's just that I didn't get as good a cpu as I'd hoped for, having to run 1.90v to get to 2.3Ghz is a bit of a bummer... Eh, can't win em all :p
