Question Is there a Socket 478 MOBO with 800mhz FSB, 4 GB of RAM, and PCIe?

[louisfriend]

I am trying to get a MOBO/processor combination so I can try running Windows 10 on a socket 478. I have a j processor with the Execute Disable Bit but my MOBO is not compatible and it only has a 533 FSB speed. Has someone done this before? I want to find one with 4 GB of DDR 2 RAM, SATA and a PCIe express port. Any suggestions would be helpful. The Intel website say the P4 Extreme editions have Execute Disable Bit support but the individual pages for the processors do not say if they do or not. Ideally I would find a MOBO and a processor with the x disable bit that does not cost $1,000. Thanks.

Well, what's your CPU?

This is going to be a challenge under any circumstances. Given that there's no dependable availability of these old motherboards, nobody can really recommend a specific motherboard. PCIE was quite new at that point, so you mainly found that on higher-end boards. All you can do is keep checking what pops up on eBay.

As daunting as these needs are, it's even more of a challenge, because such a motherboard also has a high chance of having a PCI-Express 1.0a slot, with 1.1 not being released until the transition to socket 775 was well underway. GPUs with PCIE 2.1 and later are less consistently backwards compatible with motherboards wiht 1.0a slots.

I personally do not know any 478 board with PCIE.
Latest 478 boards were with PCI and AGP slots - 815, 845, 865, 875 chipset.
PCIE started appearing with LGA775 socket boards and Core family cpus.

You could possibly get PCIE on it with PCI to PCIE adapter.

There were a few, but obviously quite rare given the release years.

Right now I have a SL7E5 (800FSB) and a SL7E2 (533FSB.) I am not sure from the look of this Intel page but since I have the 478 version of the SL7E5 does it not have the Execute Disable Bit? Theoretically both of these processors could. There is also the question of support for 64 bit, which neither of these chips have. This forum post is about 478 MOBOs with some of the features I described.

Does the SL7E5 I have have the Execute Disable Bit or not? Even if it only runs at 32 bit I could still use the lion's share of 4 GB of RAM which is the max I can hope to find on a 478 MOBO.

I currently have a 2.4 P4 478 running on an Asus board. If I had the X version of this MOBO the SL7E2 I have would work but the MOBO has a max ram of 2 GB. I bought one of the best PCI graphics cards ever made (A PCI version of the GT 9400) so I could actually live without the PCIe if I could get everything else I am looking for.

I have been digging online and finding some forum posts about it years ago.

Thank you! I had looked at that page but assumed since there was only 2 RAM slots it was a max of 2 GB. it is actually 4! I will check this one out.

This is the ultimate processor I could get. Intel's search says it has X Disable Bit, but then you click on the page and it says it doesn't?

The SL7E5 does not. All the ones that have it are either 600-series CPUs or have a J in the sSpec. The Extreme one that is the exception to this rule is the 3.73 GHz one.

As I said, if you're trying to find very specific 15 year-old-motherboards, you're going to have a bad time. You're going to have to do this the opposite way, trying to find any listings for 478 motherboards and then see if the ones actually offered meet your needs.

It's a good thing that the PCIE slot isn't a must-have for you, because that multiplies the challenges you face significantly. You could find a used HD 4670 AGP. There used to be a lot of those out in the wild given its popularity due to it being the last mainstream AGP GPU and it's faster than a GT9400.

Good find.
I think, that's what you wanted.

Most boards there are quite exotic though.

Thank you for the information. This is the PCI graphics card I have. I think I got the last one on Newegg. This listing has been like this since I bought it.
