    I bought Dell Dimension 4600 with P4 2.4Ghz and wanted upgrade to 3.0Ghz or higher. I want to make sure that I am buying a right CPU.

    The spec said I can upgrade to 3.0Ghz/800FSB, but according to user win2kpro on this thread, he said my motherboard is D865PESO, so I went to the Intel website and find this page.

    The page says that it supports Intel® Pentium® 4 Processor Extreme Edition supporting Hyper-Threading Technology† , so I follow the link which show that the motherboard supports 3.20 - 3.46Ghz/ 800FSB.

    Since Dell said supports upto 3.0Ghz, my question is can I upgrade to P4 Extreme Edition 3.46Ghz?

    The motherboard in your computer is equipped with a Socket 478 CPU interface.

    Most processors of that Socket type will run on your computer, theoretically. The fastest single core processor available for it is a 3.0GHz.

    I DID NOT say conclusively that the board was a D865PESO. I said that I was fairly certain that the board was a DELL modification of either a D865PESO or D865GLC.

    According to the INTEL site, the D865PESO was an OEM only motherboard.

    http://www.intel.com/products/motherboard/d865peso/index.htm

    Note at the bottom of the page INTEL states; "Note: This product offered to direct OEM customers only. Channel customers should refer to the Desktop Board Roadmap for future offerings."

    The processors supported by INTEL boards are determined by the AA number (revision number of the board). Most manufacturers DO NOT put the INTEL revision number on the board. The processors supported by the D865PESO are located in this table from INTEL. These supported processors may or may not be applicable to each manufacturers specifications for their OEM boards.

    http://www.intel.com/design/motherbd/so/so_proc.htm

    If DELL states that a 3.0ghz. processor is the maximum processor your board will support then you have to believe that the manufacturers statement is correct since they are the only one that knows for sure what their modification entailed.

    Well, I just guess that 2 years ago when I bought Dell it might not has processors higher than 3.0Ghz in the market yet, so Dell just put the spec just that.

    I look at the picture of D865PESO and it's the same as my board, so I figure I would try 3.46Ghz. Well, it will be pricey if it doesn't work.

    Have anyone else tried this before?

    I can confirm that OEM versions of motherboards may look the same but there are usually custom BIOS limitations that restrict the upgradeability.

    That may or may not affect you, but I have been similarly caught when the retail version supported an upgrade but the OEM did not, on an HP PC.

    The limitations, if any, are usually put in place so that any unknown problems (for future higher spec chips) will not prove to be detrimental or a support problem. Locking the ability out is easier.

    Personally, I would't try to use a processor unless the machine's manufacturer stated that it was supported by that particular board.

    Manufacturers do not have their "proprietary" boards manufactured so they are highly upgradeable. You have to be cognizant of the fact that when a manufacturer has either a standard OEM or retail board modified for their particular application the board is no longer a standard OEM or retail board, but has become a manufacturers "proprietary" board and although the "proprietary" board may look the same as an OEM or retail board there may be significant internal differences in their boards.

    This is the reason that upgrades/updates are only listed on the machine manufacturers website rather than the actual board manufacturers site. The board manufacturers never list upgrades/updates on their sites for manufacturer "proprietary" boards.

    Here's a link to the processors supported by the 865PESO board when it is an Intel labeled board. http://intel.com/design/motherbd/so/so_proc.htm Note the AA #'s listed on the side of the table for Intels most recent and Extreme processors. All of the 1 Mg cache processors are Prescotts and Extreme Edition processors.You must have a board with an AA # equal to or above those listed in order to use those processors on an 865 board. There may also be bios limitations that will stop the board from booting with those processors.

    Here is the Dell spec for the board: Microprocessor::: Intel® Pentium® 4 that runs at 2.26, 2.4, 2.533, 2.66, 2.8, or 3.06 GHz internally and 533 MHz externally, or 2.4, 2.6, 2.8, 3.0, 3.2, or 3.4 GHz internally and 800 MHz externally

    Level 1 (L1) cache
    8 KB first-level

    Level 2 (L2) cache
    512-KB or 1-MB pipelined-burst, eight-way set associative, write-back SRAM

    Without seeing your board and whether or not Dell has labeled the board with AA # sticker, I would say you are stuck with the processors that have a 512 cache level. In other words, the ones starting with 3.4 below the line that splits at 2.40A and 3.4

    Well, I did read that, that's why I started the thread here. I want to try highest possible CPU that is not listed by Dell.

    where did you find this, 3.4 GHz internally and 800 MHz externally? is it from the motherboard with onboard Video?

    I understand. I don't have the onboard video and Dell document says the system is support upto 3.0Ghz. The reason I asked because my board is Intel D865PESO, and intel says it support 3.4Ghz.

    Anyway, I quite understand now that it's Dell propritary board which may not the same as the original Intel board.

    Thank you for all the reply.

    Can I use "Pentium 4 HT 3.0Ghz 1 MB 800Mhz FSB Socket 478 OEM NEW" with my system (see spec here) ?

    The CPU is HyperThreading, but the Service Manual doesn't say it supports HT. Can I still use this CPU?

    Please advise.
