Intel 845 (478 pin) motherboard and new Pentium 4s

[DarkKnight]

Will the Intel 845 chipset support the newer Pentium 4 processors (like the 2.53ghz)? I've heard the the newer ones are build differently than the older P4s (like my 1.6 ghz).

You can use motherboards with i850e, i845e, i845g, or the i845gl motherboards if you want to use Intel chipsets due to the newer processors running at 533 Mhz bus speed. The sis645dx chipset and via p4x333 chipset will also work(whenever this motherboard is released). The i845g motherboards are supposed to have "unofficially" DDR333 and the i850e is supposed to unofficially have "PC1066" rdram support if you buy a vendor's motherboard(Asus or Iwill).

how about the normal i845?

If you mean the 845D, it supports 533 MHz FSB just fine, just "unofficially". Tons of people here doing it.

uh... doesn't it depend on what the BIOS gives you? I thought that some of the 845D boards didn't give you all you needed to do this.
I mean, if it won't let you 133 then that's that. Also if it doesn't give you dividers or locks for AGP/PCI, won't that bong you also? I won't even ask about memory multipliers.

Only answer I could come up with is: I would sure check my BIOS to see what options are available first. I don't doubt that many boards let you do it. But I doubt that all of them do.

Good point. It depends on which 845D board you have. It must be an "overclocker friendly" model.

Intel has several I845 boards:
i845e, i845g, i845gl and i845

will the i845 (with no letter after it) support the new processors? I looked at the Intel website and it says that the i845 only supports 400mhz FSB.

It would help if you told us the exact mfgr and model of your motherboard.

Using the Belarc Advisor I got these results:

Board: ASUSTeK Computer INC. P4B266LA REV 1.xx
Bus Clock: 100 megahertz
BIOS: Award Software, Inc. 3.02 11/22/2001

An Asus P4B266 certainly can support a 533 FSB CPU. You have that "LA" at the end. This is some sort of HP OEM version I guess. Send a PM to AndyHui. He may know more about the OEM version.
