Upgrading old Dell Dimension 2400 CPU, GPU, Memory, etc.

Jump to solution

Primarily interested in CPU upgrade at this time. I downloaded CPU-Z to determine my specs, and am providing this stitched-together set of screenshots from that program:

I just upgraded the CPU on my friend's Dimension 5150 with success. I would like to replicate that on my 2400 - a much weaker machine. This computer is primarily used for casual internet browsing and occasionally watching a Youtube video. The only programs that really tax the CPU are my disk defragmentation and the program CCleaner. When I have a large internet browsing session of 100+ tabs, the CPU is also taxed at that time. 

I would like to max out this computer using cheap upgrades parts I can buy on eBay. On my friend's 5150, I bought an upgrade CPU for $5 shipped and a thermal paste from ebay for 80 cents. I wouldn't mind buying a cheap video card and a CPU to upgrade this old workhorse

With the home version of windows being $109 and the Pro version being $199 its not economical to upgrade a vacuum tube computer to windows 7 or 8 or 10 when you can get a newer 240% faster machine WITH 2 gigs of ram AND windows 7 for $99.  The windows 7 alone will be more than that.

Install a new micro-ATX motherboard and memory.

That right there is an excellent buy. However if I were looking at cheap and small, I would rather do a Winbook tablet (like my TW-700) connected to my existing desktop monitor for $70, which includes windows 8 and a year of microsoft office 365.


What I'm trying to do, however, is to max out, not my post count (as others try to do), but the specs of my old Dell laptop. I know I can do it for less than $40. Like I said, I upgraded the CPU and RAM on my 5150. It cost $10 shipped for the RAM and $6 shipped for the CPU and thermal paste. I just need to know what parts to buy on eBay for my Dimension 2400.

 The Dimension 2400 can use either 400MHz or 533MHz, Socket 478, P-4 Northwood, or Celeron processors with a 512k or smaller cache.

You cannot use any Prescott processors [1mb cache].

The maximum supported processor is the P-4 Northwood, 533MHz, Socket 478, 3.06 GHz.

Prior to upgrading the processor, check that you have the latest BIOS version installed.

Regards to the video card, only PCI cards are supported, no PCI Express cards are supported.

The Dimension 2400 supports a maximum of 2GB [2x1gb Modules] of DDR memory.

Unlike the 5150, it employs an architecture bordering on obsolescence even when new.

There is no cheap way of substantially boosting performance. A faster processor isn't that much help, considering that the video and storage are both major bottlenecks.

BIOS  A07   0HJ054 LGA 775 Socket T  DDR2 motherboard version of the E510/5150 motherboard works fine with Pentium D Pressler 900 series from 915 to 945.  It supports 3.25 gigs of ram and windows 7,8,10. It has a PCI-E X16 video slot and 305W power supply.  The 2400 has none of these features and never will.

E510 does not support Core2 duo. 

The Pressler vs Smithfield can do LAHF and SAHF as well as CMPExchange16 which means it works fine if you have a 900 series Pentium D.  That means you can run 64 bit windows 7 or 8 or 10 just fine.  Max useable ram will always be 3.25 gigs regardless of cpu or os being 64 bit or not.  This is a chipset limit.

The 5150/E510 can do this(with caveats like Bios A07 and the Copper Heatpipe Heatsink Exactly the same as the GX620. Motherboard Version 0HJ054 supports the Pentium D without issues up to 945..E510  from Oct 06. The Pentium D 915 is the universal CPU which works in Tower or even low profile or SFF or USFF when it has the copper performance heatsink.

On older GX320,330, 360, 520,620,745,755,760,780 and Precision 380 or T3400 a bios update may be required for Pentium D 900 series to work.  An additional problem is that Early 5150 models need Bios A07 and they will stop on Unsupported processor Press F1 to continue. This is only older boards.  Other than having to press F1 it works fine.  I'm running 64 bit windows 10 on one right now. The crossover machines were the Mr Smith Mini Tower GX280's  They look just like the GX620 but the board in them is older and there is no Pentium D support.

I got my 8.1 pro upgrade back when it was $38.  If they want that they should buy it immediately because there will not be any in the future.

WINDOWS 8.0 is depricated and the Purple box 8.1 home and Blue Box 8.1 pro are the available everywhere retail options.

After Oct 31 2015 8.x may be gone forever as well being replaced by Windows 10.

Pentium D 915's are very cheap as is the copper heatsink.  The ram and windows license are the expensive parts.  You update the bios to latest then change the CPU and replace the thermal paste.  The Dual core pentium D is an improvement.

RE: Upgrading old Dell Dimension 2400 CPU, GPU, Memory, etc.

About a year ago, I upgraded our Dimension 2400 with a new motherboard, CPU, RAM, and Power Supply. I already had some of the parts so it wasn't too expensive - these are the parts that I installed:

  • Gigabyte GA-78LMT-USB3 Motherboard
  • AMD Athlon II 260 (cheap / used from eBay)
  • 16 GB Corsair DDR3-1333 RAM
  • Antec 400W NeoEco Power supply (already had it)
  • 2 SATA DVD burners
  • 1TB SATA WD Blue harddrive (already had it)

I loved the size of the case and that it doesn't scream "expensive" (steal me!). I really wanted a brand new PC with the old Dell case. All of these parts all fit nicely into this case - the only challenge was the power button / LED indicators as they had a proprietary connector that went to the old Dell Motherboard. After a lot of searching and thinking about just splicing the existing wiring to standard connectors, I found a StarTech harness replacement kit (StarTech BEZELWRKIT) for about $6:

www.newegg.com/.../Product.aspx

The power and reset buttons fit the original Dell bezel perfectly. It didn't match the LED size perfectly, but I was able to get the bigger LEDs to fit into the plastic holders with careful force. Now I have an "old" Dell 2400 with brand new internals - tons of HD and RAM - and best of all - Windows 7. It runs many times faster, never crashes, and it sleeps when I'm not using it (the old OS / Motherboard ran 24/7) saving power and not filling with dust. I haven't had any problems with it since and it seems to run cool.

The photo below is midway through the upgrade. I also added an Antec 92mm SmartCool temperature controlled fan to the back of the case using the existing holes. All-in-all, this case is very upgradable. The only thing that I couldn't connect was the case USB on the front - I use a USB3.0 port on the back connected via cable to a 4 port USB3.0 hub on my desktop which is more convenient anyway.

I guess what you are saying is that the

StarTech BEZELWRKIT Replacement Power Reset LED Wire Kit for ATX Case Front Bezel switch assemblys can be fitted.

The old LED's could be re wired to the new setup I suppose.

The switches fit perfectly - that was the part I was worried about and I really wanted new switches anyway.

As I remember the Dell case had a mix of small and standard LED indicators - the StarTech kit had all standard LED indicators. The standard LEDs fit and for replacing the small LED, the plastic clip that holds the LED was just "stretched" a little and the standard LED slipped in without cutting / changing anything on the bezel. I certainly could have spliced in a small LED and done new heatshrink tubing at the solder points but there was no need - it worked well.
