Optiplex GX240

[Charlemagne_3]

Just acquired a dell optiplex gx240 (bleh) and am looking for parts for it. I am trying to find out what the best CPU to put in is. I have already come to understand thats its 845G chipset only supports up to 533MHz FSB, but I have found conflicting info on the frequencies, caches, and cores (ie, prescott) supported. Can anyone help me?

Also, I was wondering if a 3.06ghz/533/1M northwood is better than a 2.8ghz/533/1M prescott is better. Because I believe I already have that prescott lying around, and i f so, it may turn out to be the best one, unless the info on supported CPU's so far is wrong.

If you find anything please source it for assurance.

You could've just told OP to wish in one hand..... and.... well you know how the rest goes... 🙂

Hey Guys I have a GX240 and man I love this thread, it started off really good full of great info then degraded into a full blown tit for tat with a die hard I just can't say "I don't know what I'm talking about and say thanks", and then move on." cham Wow Main should just give it up and accept under the bus spead it does say 100/400 max and they're not going to update it. As far as the BIOS there is a guy who might have one or be able to do it; http://biosman.com/. But why, just throw a $20.00 dollar warrantied china special in it like I'm gonna do. If it works great, if it doesn't so what, I'll throw my old P4 in it and get a new system and use this one for surfin etc like someone here in the thread said.

I do know that the P4 2.6Ghz 512/800 will NOT work in this machine, I put a brand new sealed in a box in it and it came up bus speed error.

If the new 2.6Ghz 512/400 works I'll post it. It should take about a week for me to get one in and find the time to install it. Yall have fun and keep up the great come backs, it's what actually got me to send this post instead of gleaning the info and moving on. I mean like my son and I were all over the floor about to puke from laughing so hard! :lol:

Cool
I am glad you got a good laugh
I hope you stick around.
There are some really smart forum members on
here with good info.
Of course the classic AMD Vs. Intel and Nvidia Vs. Ati/AMD
threads are always fun to read.
If you decide to buy an OEM and get one used
look into the Optiplex 745/755s
They were bought in bulk by companies and institutions
and are starting to get cheap on US Craigslist.
THe 745 handles low end Core2Duos
and the 755 will do Core2Quads.
Though the best bang for buck is building a AMD system
from scratch.

CPU Upgrade:
Ok as promised I got my new CPU in, I installed a P4 Socket 478 2.8Ghz/ 512 Cache/ 400 FSB(SL7EY). Use the last info in the parenthesies to do a search for the chip. It works great!
I bought it off ebay from Chris at:
http://stores.ebay.com/home-made-computers21?_trksid=p4340.l2563

Chris was a pretty cool guy, I had so many questions in my emails he just sent me his home phone. We talked about Comps for awhile and even offered me a refund or a swap if the CPU didn't work. I did cost $40.00 bucks but it was tested and came with a waranty. He deals in a lot of older stuff but does fix the newer stuff too. Be nice to the man and he'll fill your ears. I even said my Dell is only rated at 2.6Ghz he said a 2.8 would work fine. I ran it under the A01 bios and upgraded it to A05 and it ran under both. If you intend to run the Bios update make sure you have the A drive hooked up and a blank disk. It was very easy and I didn't notice anything different.

Video upgrade:
Well bad news here so far. I installed a PNY GeForce 8400 GS PCI slot (NOT PCI-E express) and it did not work.

A little dialog if you please:
This computer does not have the PCI-E slot and it won't work for those of you out there who would love to try. If you do get it to work HE HE please let the rest of the world know how you laid hands on it and got it to heal itself. Ok off subject here, back to the video card.

A little backgound info:
Although I sould have bought an AGP I did choose the PCI over it for two reasons:
1. I plan to get rid of this computer some day & I wanted to run the PCI on the new computer. Now before all you guys say, "Just buy a new computer!", guys let me get in there and say this card ran Bethesda's Fallout 3 on high graphics with barely any lag. We dropped it down a notch and had no lag at all. He is a seriouse gamer and said he was really inpressed with the card.
2. If the card worked in the Dell I could hold on to the computer a little longer or continue to use it in the computer and just simply buy a better computer when I have the cash.
3. I could put it in my wife's machine for here to use. Ok that was 3 not 2 reasons!

Things we tried to get it to work but to no avail on the Dell GX240, but may help in other machines:
1. F2 setup Integrated stuff left it on AGP and installed the card.
We left the monitor hooked up to the AGP card. Then loaded the nVidia drivers, it recognized the Card on set up and in the Device Manager under Video Adapter. Then we rebooted with monitor hooked up to the GeForce (PCI slot) video card. During the boot up it recognised the card and it's ram. When the windows screen was supposed to come up it went to the black screen of death.

2. F2 Setup set the video to Auto and left the AGP in, and the monitor still hooked up to the GeForce PCI Video card again it recognized it but gave the black screen of death when windows went to boot. By the way Dell Pheonix Bios does not give any other options for Video except AGP & Auto for the Dell GX240 model.

3. Went back to setup no 1 except we left the GeForce card in and hooked up to the AGP Card booted up in windows then set device manager Video adapters to disable ATI graphics adapter. Then rebooted with the monitor connected to the GeForce Video card, again black screen of death. We tried some more variations but came to the conclusion that either the chipset or biose did not like the nVidia card. My IT guy said that some computer manufactures in the past would set up their systems to favor certian hardware manufactures to get good deals on the hardware. This was good and bad. Good for you in that the computer would cost less but bad in that your flexability is limited. Hence do some research before you buy and get what you want.

Future Video upgrade:
I'm looking into buying a nice ATI Dual DVI 512mb or higher AGP video card and see if it will run an ATI AGP, since that's what's in there, only at a lower ram and speed. When I get it in I'll post the results for you dinosuar upgraders like me. As for you newer computer guys out there, face it some of us have seriously limited budgets and dropping a $100.00 bucks is alot and $350.00 and up to play a video game, well it's not gonna happen for a year or two for some of us. So we buy cool 3yr old games and buy old used stuff and eat our cake later instead of today. It may not be glamorous but we still get to have a lot of fun. The other good part about this for you more up to date guys is you get relearn some of this stuff you can fix you girlfriends piece of junk or your cheap friends systems like me.
Well until next time or the next suceessful Dinosaur upgrade I'll be seeing you later.

Ps Presario SR1200NX:
Before you ask about the PNY GeForce 8400 GS it did find a home in my Compaq Presario SR1200NX 2.0Ghz Sempron with 1Gb of PC2100/PC2700 mixed 512mb DDR RAM. It runs the Command & Conquer "The First Decade" on the highest resolution for General and some of the other games. It will run it on the highest setting for Renegade but has a little lag.

PSS if anyone knows if I can run a faster AMD CPU in it let me know. Also I have seen stores selling 2GB of Ram for the Compaq Presario SR1200NX. The system only says it holds 1GB. If it will hold 2Gb let me know would ya. Thanks Al B. Slidell, La.

I too bought the PCI 8400 GS, same reasons as you, older system, no dedicated graphics bus, so I made do with what I had. One thing I discovered is the 8400 GS, because it's on a limited (and shared) PCI bus, doesn't play well with other PCI cards. You'll need to take out ALL OTHER expansion cards to get it to work.

After you try that, if it still isn't working, try taking out your AGP card and booting off the PCI card.
