Chipset vs socket type

[eraser82]

i'm working backwards in replacing a motherboard for a dell comp.

i know the chipset is 845 and that it falls under the 475 socket type motherboard,

what i'm hazy on is if all 475 socket motherboards will work with all 845 chipsets, or if there are some that wont and that the 475 motherboard must state that it supports the 845 shipset.

Intel® 845, 845E, 845G, 845GE, 845GL, and 845PE Chipsets Support for DDR333/266 memory, the 845GE variant chipset has integrated Intel® Extreme Graphics.

ALL chipset variants were used primarily on socket 478 based motherboards (not 475??)

They support 400/533 front side bus CPU's thats 533fsb Intel P4's and Celeron's (not the newer Prescott)

Your question doesn't really make much sense and I'm not sure exactly what you want to know but I will take a guess.

Be aware that some Dell units use there own proprietory motherboards (motherboard they have manufactured to their own specifications) this can often cause problems with replacements as the power supply wiring can be differant on a Dell so standard ATX form factor Intel 845 chipset motherboards sometimes just won't work.

Well a quick answer would be that the socket and chipset are all on the motherboard. You shouldn't have to worry about compatibility between the two, since replacing the motherboard replaces both.

However, give special attention to paparazi's comments about Dell wiring and proprietary parts. Newer Dell systems aren't that bad, but older ones like the one you have were.

@Paparazi - Good info... but need to correct you a bit there, I have a ASUS P4PE-x a 845PE chipset Mobo that supports a Intel P4 Prescott at a FSB of 800...

That's a good point Ben. There are many versions of the 845 that do support DDR400 and an 800MHz FSB. However, Paparazi was merely pointing out the default specifications of the 845 chipset. Only certain manufacturers, like Asus, have gone out of their way to add support through BIOS upgrades.

If you dig a little deeper, you will also find on Asus's site that the 845PE actually doesn't support the Prescott CPU. According to this link, only the Northwood and Williamettes still qualify:

But if it works for you, great! That means that Asus just didn't state that it will support Prescott socket478 versions. Just thought I'd mention that...

1) I've got an i845G board here that supports no higher than 400fsb, so that's a concern to look at as well when replacing, what the fsb is.

2) Different i845G boards are not always a compatible upgrade for Windows, in other words, you cannot swap one i845G board with another and expect Windows to boot up. It may work, but it might not work (and you'll have to reload Windows from scratch).


I've upgraded a Dell before, and it's not that bad. You'll just have to buy a new cpu heatsink/fan, probably will be too tough to work with the current Dell setup.

Hola, Cdogg...

Hmmm... nice link...

http://www.asus.com.tw/support/cpusupport/cpusupport.aspx

if you scroll down to the end... there it states that it supports the Intel P4 Extreme Edition, which I thought came only in the Prescott variant...

I must admit, I do not use a P4 Prescott on my mobo, thought it was a waste of money at the time, I used instead a Celeron at 2.8ghz Northwood Core...

Guys I was generalizing and should have said that there are acceptions but as the main topic was basically the compatibility or otherwise of a replacement motherboard for an 845chipset based Dell mainboard I really didn't think it was relevant.

One more thing, seems to me you not only have to watch out for proprietary motherboard but proprietary power supply as well.
I think you need to know that Dell uses both proprietary motherboard and proprietary power supplies, so if you replace the motherboard you have to get one from Dell. If not then you may also have to get a new power supply.
At some point and in some models Dell changed that and went with standard mobos and power supplies, i dont know in your case.


Good advice + great people = tek-tips

If you have the motherboard model number go to the asustek website and download the manual in PDF and read all about it. Also look at the download section and read what the downloads for BIOS Updates say that they fix or what they specifically address.

Asus often puts support for features that are not directly supported by the chipset such as Overclocking. Often with these added features other processors that were not available when the chipset was designed are supported even if the manual does not mention them.

Just dont expect miracles.

If you do not like my post feel free to point out your opinion or my errors.

 

[BadBigBen]

Sorry,

but I was just pointing something out, that I thought that one of the Board Guru's (Paparazi) might have missed, not intending on flaming anyone...

@ceh4702 - I won't need this info, as I am not going to upgrade the PC anymore, next would be a mobo with a 915 or 925 chipset and appropiate CPU... or an AMD64 with appropiate mobo...
