CPU Upgrade

I have the Intel D845EBG2 socket 478 motherboard. I am currently running the 2.26 CPU. I am considering upgrading to a faster CPU. Will this MOBO run the 3.06 G CPU? The mobo and cpu are both rated at socket 478 and speed of 533 Mhz although intel website doesn't list it as supported.

Thanks !!!!

oldguru! Welcome to the forums. I don't think the 3.06GHz processor will work. I see no mention of support and in the BIOS release notes I see nothing about adding support for it -

I did a quick Google search and pulled up this page: ... 008639.htm

It looks like a Pentium 4 2.80GHz processor will be the fastest supported. That processor runs on the same 533MHz bus and offers a 24% boost in clock speed.

If you really wanted to keep that computer it sounds like it would be worth the ~$4 to get a 24% boost in clock speed. Be sure to update to BIOS P08 before changing processors.

Thank you for the reply!!! I believe tho that the three links you gave me were for processors with bus speed of 800 and 1 at 1000. My mobo is rated for only 533.

thanks again!!

That you are right...

How about the Intel SL7E2 - ... MHz-FSB%29

Not 100% sure it would work, but it has double the cache, runs at 533MHz and is for socket 478.

It's also $4.90 shipped, which is still great - ... 1009094249 ... 0842193998

The only hitch with that one is if the BIOS for your board will support it.

If you wanted to play it safe get the 512KB cache version - Intel SL6PF ... 0801872550
