Hi All,

I was wondering if anyone on the list has experience upgrading a Dell Dimension motherboard?

I have a Dimnesion 4550 and the mobo has a 4x AGP slot. I broke on side of one of the ram slot clips. So I wanted to upgrade to another mobo with 8x and more RAM slots.

The PC has a P4 2.66 GHZ, DDR 2700 RAM and 4x AGP.

Any advice? Anything I should be aware of since I have a Dell? Will any mobo fit in the case? And what about the chipset (845ge)? Do I need to stick with the same?

Thanks,
Mark

 
If the case uses the standard ATX form factor, then you can almost put any type of MOBO in there...

as to sticking to the same Chipset, well that is really up to you, as you mostlikely, if you use different mobo, have to reinstall the OS (W2k or XP) to be on the safe side... (Win98SE if more forgiving than the others here, but you should still delete withing the Registry the ENUM (hardware related stuff) Key(s))...

firstly, find out the formfactor of your case

the standard form factor nowadays is ATX, however since you're using a dell, that's not guaranteed...

if you want to upgrade your mobo, and your case isn't ATX, then you might as well just get a new case, you can get some quite good cases quite cheap...

as for your chipset, well, the 845 is quite common, so you shouldn't have too much trouble if you stick with that...
 
My case is an ATX.

I don't want to stick to the same chipset if I don't have to, as I see more of a selection by looking at others. Like the 865pe for example. There seems to be a good selection for these.

Any recommendations? I have a decent gaming rig, so gaming is my number one area of concern.

I want to go up to an 8x AGP and get a newer video card. Ditto for better RAM. But is there anything else that I should look for in a mobo?

Thanks all.

For gaming, I would suggest a mobo with either 865 or 875 Chipset (with LAN build in for Lan Gaming), a nVidia FX5950 Ultra or a ATI 9800XT gfx card, with DDR400 (PC3200) RAM, and a P4 3.0 ghz (Prescott) (or better) CPU running at 200 mhz (Quad pumped to 800mhz)...

Ben

My opinion...

PS - a comparable AMD system would do the same for less money, but by upgrading only mobo and gfx card and keeping the P4 2.66 ghz is cheaper and also very good for gaming...
 
First thing I would do is this: make sure that your case front panel connectors aren't preassembled into one piece to only work with that board, since all front pin connections aren't identical in location (I noticed this when was going to upgrade the motherboard/processor of a slighly older (500mhz) Compaq Pressario desktop. If you want to see how the diff motherboards stack up, try looking at - they've got really good reviews about anything hardware for computers. They regularly compare multiple motherboards, processor, video cards, sound cards, cases, monitors, etc. You can also check out , , and for info. I prefer to look at when looking on the web, first, as they have tons of info (mostly hardware), it's 100% free w/o any kind of memberships necessary, and they don't side with any one manufacturer, they just tell it the way it is.

I am checking out the article on Tomshardware.com on 18 P$ Mobo's. Just what I wanted.

But what if the mobo has 8x AGP and my card is 4x? Will I be forced to buy a 8/4x AGP slot mobo if I want to keep my card?

Mark
 
From what I've read from most of the mobo manufacturer sites, it seems that most are 4x/8x compatible if they are 8x compatible (you might just have to set the BIOS options for it when you boot the machine (if it's not set to auto detect whether 4x or 8x. I would just check the manufacturer's website for each board. From what I've seen, you can't go wrong if you buy an Asus, Gigabyte, or MSI board/video card. MSI seems to have the best scores with identical chipset, whereas Gigabyte has the best features. Of course, you probably won't notice any difference in performance. By the way, unless you are a die-hard Pentium 4 fan, or you have to do something such as lots of video editiing/encoding, then an Athlon XP, or especially the Athlon 64 line would be the best bet. Assuming the front panel connectors are not the way I mentioned in my first post in this thread, then any mobo would work, as long as it fits. Also make sure your current power supply will support all the hardware you have. If you get a higher end processor and/or video card, then you may end up needing to up your power supply as well. Best bet is to search google for reviews of individual boards, and check the manufacturer's web site. Dell uses Pentium 4 as apposed to Athlon, as they have a contract with them. They had a similar contract a while back with Rhambus memory, but b/c Rhambus never did very well (so far to date), Dell eventually dropped them, and went to the more conventional DDR memory as apposed to Rhambus Rimms (not Dimms, but Rimms) [SMILE].

Hope this gibberish helps...

Stephen,

Just for the record, I am keeping everything but the mobo (and RAM if it's different).

I have a faulty stick of RAM from Kingston, so when I get it, I will keep it unopened until I buy the mobo. If the mobo uses different RAM, I plan on selling the stick of 512 from Kingston and buying a new stick for the new mobo.

I have subscribed to maximumpc for about 3 years and went through some back issues and found a few mobo reviews that I think will help.

Thanks,
Mark
 
Howdy,

Something you need to consider when purchasing a mobo is the I/O connector layout. Your Dell case may or may not have a punch-out panel to allow for aftermarket I/O shields. If not, then to upgrade the board without buying a new case, you have to make sure all the connections on the motherboard are in the same positions.

I learned this the hard way when I tried to build a PC in an old Gateway case, but even if you are unlucky like me, a new swingin' case not only is fairly cheap, but can be downright awsome [thumbsup2]!

Good luck,

One more item to check- the number of pin connectors from the power supply. Seems even Dell is beginning to use proprietary items...

The test continues...
 

A word of caution!

< I am keeping everything but the mobo >

If you browse elsewhere on this forum, you should find some discussion of Dell power supplies and mobos.

Dell use the same power connector as specified for ATX but they use a non-standard pin allocation, i.e. the various voltages are on different pins from the fully ATX-compliant PSU or mobo. This means that if you change to a non-Dell mobo you should also change to a fully ATX-compliant power supply (and vice versa).

I'm sorry that I can't give you the exact thread number just now. One of the posts on that thread includes a link to Scott-Mueller's on-line book; you might find that via Google.

Hope this helps.


Best regards,

Pete W.

Yes, meckeard, make sure to look at all the connections for your Dell computer before just getting a motherboard. As I mentioned earlier, and a couple others have mentioned, check your front panel connectors (power button, computer speaker, reset button, power led, hdd led, etc) to see if it is all in one piece or in multiple small pieces. If it is all one piece (easier on the assembler), it will be impossible to use that with another motherboard most likely (unless you intend on doing some serious wiring - such as taking the wire assembly apart, using new connectors, or somehow just making sure the correct wires go in the correct holes - good luck if you try that route. Also, as mentioned by another, safest bet would be to get another power supply - you don't want to mess things up by having the incorrect voltages for sure, and if that's the case as pudda and PeteW mentioned, you could do some serious damage, and a doubt a warranty would cover "oops". [SMILE]

It seems that when dealing with upgrading the motherboard from something like a Dell or Compaq, or some other OEM manufacturer, the easiest/safest thing to do would be this: Take the components you want to keep out of the Dell case, such as your hard drive, CDRom, etc, and buy you a new case. A cheap case that has some really good options, good airflow, and extremely quiet is Chieftec. I have a coworker here who also builds computers for himself and others, and he has just fallen in love with the Chieftec Dragon series. They have both Aluminum and Steel models. One good place for finding those cases is . I've had some good experience, and some bad with them, but they are a fast shipper, and I doubt you'd run into any problems with buying a case from them - the other person I mentioned has had no problems with them to date. You can get a Chieftec case anywhere from $50 to $100+ USD. Usually, if you get one with a power supply, you'll pay at least $70 or $80.

Anyway, if you feel comfortable with it, and have done your research to make sure it will work, you can keep the dell case, otherwise, you may need to get a new case. There are various good case manufacturers, but Chieftec would be a fine, cheap, choice. You could also choose an Antec model, as they all seem to be good. I'd advise against Skyhawk, as I have 2 at home, and have built a few machines with them. The main issue I have with them is that they do not operate quietly, whereas the Chieftec cases seem to operate at next to silent levels. The next time I build a computer, I plan to use a Chieftec case myself. I'd prefer the Aluminum models as to Steel for 2 reasons (better heat dispensation and they are much much lighter).

Anyway, just make sure you do your research, and try to read articles for any/every part you purchase. What I do often, is just talk to Mr. Google. [WINK] The way I do it, is find the model# for the product, or the name - try model# first, and use name if that doesn't work. I search for that piece of info first, and then "search within results" and type "Review" in the next block, and the first few links (at least) that come up will usually be a review that some individual or group has posted on the web, such as Tom's Hardware, OverClocker's cafe, etc.

Also, you can check for info on and some sites, including allow customers to post their opinions about products - do not go solely by any info such as this, but you can often get an overall picture of the product.

One last suggestion: If you end up getting an AMD processor, it'd be adviseable to get a namebrand heatsink/fan, and not stick with the stock hs/fan. I switched from my stock heatsink and fan to a Thermaltake Silent Boost - got from - and it reduced my cpu temps by around 20 degrees Celcius, that is a huge difference. One other item I picked up was some Artic Silver 5 for the thermal pasted, and I followed their instructions for assembly to the letter. That's always a good idea, as the manufacturer generally knows the best way to use their product. I used Artic Silver's instructions, not ThermalTake's.

I hope that will put it all "in a nutshell" for you.

By the way, if you chose the option for it, the demo CD that comes with Maximum PC is really cool, as it has good game demos, and many differrent freeware/demo utilities and various programs. That is where I first learned about ad-aware and spywareblaster for spyware, as well as AVG free antivirus, as well as many other programs. It's also where I found out about Call of Duty when it first came out - still the best game, in my opinion. [SMILE]

Wow, lot's of good feedback!

I emailed Dell for additional info on the mobo. If it's a proprietary one, I will opt for a new case. I love the cheiftec series too and wouldn't mind getting one.

Thanks all.

Mark
 
Oh, I have another question....

My cpu has a 533 fsb. Does this dictate what chipset I can use?

I was paging thru an old issue of maximum pc and noted a reference to 800 fsb CPU's using the 875 and above chipsets.
Is this true?

Thanks,
Mark
 
If you want to get a new mobo, but keep processor, just make sure the new mobo supports the exact same processor.

Hi there, Meckeard, I have a mobo by ASUS that uses the 845PE chipset and it has support for 800 FSB P4 (Prescott) models... so you see even some of the older chipsets from Intel support the faster P4 CPU's... but for gaming it is just a tad slower than the 865 or 875 Intel chipsets... what kjv1611 said should be considered, most newer type mobo's do support the 533 FSB P4 cpus aswell as to leaving enough upgrade room for the future...

Ben
 
Howdy,

kjv1611 mentioned the front panel connectors...

Well, I ran into this issue on a previous machine I built. If the wires are all connected into one plug-in block, it is not that difficult to rearrange them. Using a straight pin, you can pull back the plastic retention clipand slid the metal pin out. Then just re-insert the wires into the correct positions, they will snap in when you get them all the way int, and you are ready to go. I would just double and triple check that they are lined up appropriately before "firing" the machine up [wink]...

Good luck!

No! Try not. Do, or do not. There is no try. - Yoda
 
Hmmm.. never actually considered taking them apart, but the idea is very very interesting to me. I may look at that some time in the next week or two with a spare machine sitting at my house. [SMILE]
