Pentium 4 and DDR3 compatibility

[Vigaenson]

L & G:

I've got a spare Pentium 4 and I would like to take advantage of it.

It was packed in a box with stickers at its side
In one of them you can read

Intel (R) Pentium (R) 4
Processor 631+
Supporting Hyper-Threading Technology
3 GHz
800 MHz FSB
2MB L2 Cache

In the other one you can read

Intel (R) Pentium (R) 4 Processor 631,
LGA775 Pkg, 3 GHz, 2MB L2 Cache, UP only
Requires electrically compatible board - PCG06

PACK DATE: 04/18/07
Made in Costa Rica

The following symbols are engraved on the side of the processor that faces the fan:

INTEL (M) (C) ' 06
PENTIUM (R) 4
631 SL9KG COSTA RICA
3.00 GHZ / 2M / 800 / 06
3708A044 (84)

Those symbols that are between brackets should be read as if they were inside a small circle. The content of the last circle is so small and difficult to read that instead of an 8 it could contain a B or O or a 0 with a horizontal line dividing it in two equal parts.

It worked perfectly on a LGA775 socket of ATX (24,5 x 30,5 cms) motherboard with DDR2 800 / 667 / 533 SDRAM four slots, dual-channel (8 GB max)
It also worked on a LGA775 socket of a microATX (24,5 x 19 cms) motherboard which supported 2 unbuffered DIMM of 1,8 Volt dual-channel DDR2 400 / 533 / 667  (4 GB max).

I've failed in trying to find those same (new / out of the box) motherboards for this processor, and though I still haven't abandoned the search, my expectations to find them have decreased substantially.

All the LGA775 socket motherboards that  I have been offered  support DDR3 DIMMs.

I've  also failed in searching the web looking for an answer to this question:

Is my Pentium compatible with that sort of RAM?

Could you please answer this for me?

Thank you for your time.

The MBoard that supports that CPU will also be the determining factor on what style of RAM is supported...

[Vigaenson]

Thank you patio for your fast response.

But do you mean that if I find a motherboard that supports my P4 and also supports DDR3 RAM the compatibility between P4 and DDR3 can be considered established?

Thank you for your time!!

[patio]

No.
What i meant to state is whatever MBoard you find that supports that CPU will determine what RAM is supported by the MBoard chipset/layout itself...

[Raptor]

Since Intel processors do not have an onboard memory controller, it's down to the mainboard. So if the mainboard supports DDR3 and it supports the processor you want to have, it should in theory work.

Most likely NOT the answer that you were hoping for =

  Thank you Patio, Raptor and truenorth
Sorry for the delay.
I was about to send Patio an Raptor the following message

Thank you both.
I have no difficulties in understanding what Raptor has written.
If Patio can use this thread to agree with Raptor's statement my problem will be solved.
Please Patio, it's your call.

when I happened to read truenorths message which was quite disturbing.

So I postponed my message and visited truenorth's link which sincerely shocked me.

When I recovered, I spent all my free time searching the web, looking for other reliable sources that would/could support geek-in-training's point of view and the opposite point of view.

Unfortunately (and for the time being) I can only use the computer I described at another post and that entails some limitations.

Using it I have found strange things I'm planing to comment in my next post.

Best regards.
