wanting to upgrade dell optiplex gx300 (slot 1 pIII 667mhz) to dual cpu's

I currently have two identical pIII 667mhz cpu's, one of which is in the system currently operating with  dummy card in the second slot the other has been tested and is working fine, I just need to know what to do as far as the actuall hardware upgrade what I need to add and how to set it up I'm wanting to run win 2000 server as my os when I get the hardware configuration right, please inform.

Could you give a little more info as far as other system specs? I didnt see anything about RAM or hard drives or networking components. If you could give me that info, I could make a recommendation as far as to what upgrades you may need to do. As far as actually running Windows 2000 Server, you dont need much, as far as the system requirements go. Here's a link to Windows 2000 server system requirements on microsoft.com http://www.microsoft.com/windows2000/server/evaluation/sysreqs/default.asp 

I hope thats enough info to get you started. I'll make sure and check back as soon as you post those other system stats k? Good luck!

i'm also agreed with the Corey's suggestion,
sure ,you can make an upgrade it depends on how much money you want to investigate in this upgrade?
for the cpu upgrade you need a slot -t adaptor which will give you a chance to put a tualatine core cpu on your motherboard up to 1,4GHz ,to see rthe maximum amount ram memory which could be handeled by your BIOS please run the programe BIOSAgent and check out the values:
http://www.esupport.com/biosagent/,,,
if you want to make a server configuration then seek for raid configuration of your hardrives,as best try to find some quick scsi hdds which are identical,but it will surely cost,,,
it would be funny if you spend too much money on the upgrade and you could get a pretty quick desktop system for the cost-if you think that a desktop system will solve your problems with the server applications then you would rather go and buy a such one...
as Corey, for to run win 2k server you don't need more than your pentium III 667MHz ;256 MB Ram and two pairs quick harddrives which are in raid configuration :stripped -quick,RAID 1 medium speed but safety or RAID 0 + 1,,,if i was you i would spend money on getting quick hdds for to make the raid configuration on both of the systems.

just in this way of speaking: http://support.ap.dell.com/docs/systems/opgx300/en/index.htm

In order to use two CPUs in an SMP (dual CPU) configuration, it's not enough that they both be "pIII 667mhz cpu's", they have to be of the same "stepping", and that stepping has to be one that supported SMP (not all steppings do).  The stepping is effectively determined from the "S-Spec" of the CPUs, which is a series of numbers on the CPU itself.  If your statement that the two CPUs are "identical" is literally true, then the only question is whether or not their stepping supported SMP or not (again, it's not a given that they will).  However, the first thing to determine is whether or not the "S-Spec" of these two CPUs really is the same.  In other words, are ALL of the numbers on the CPU the same?  The "S-Spec" is a number like "SL2U3" (taken from a slower P2 that I have have here on the desk).  S-Specs can be looked up on the Intel web site to get a full description, including whether or not SMP is supported.

Beyond that, if you find that yes, they are truly identical and, yes, they support SMP, there are probably some jumper changes on the motherboard.  You would have to consult Dell documentation for that, or determine who made the motherboard and if it's the same, or nearly the same, as a retail model (e.g. Asus made SOME Dell, HP and Sony motherboards, some of which are similar to some Asus retail models).

Hello again, and thankyou for all of the coments thus far, as far as the specs go I have 256mb currently on the mb and a max of 1 gb, lan and audio are also built on to the mb, 32 mb graphics card, cd-rw, dvd-rw, floppy, 4 ide hd's ( 20, 40 80 and 120 are there sizes in gigs). I did double check the cpu's and yes all the #s match they are identical sl3xl's. Not really sure i understand the slot t adapter comment? and not really interested in the raid configuration, I would like to obviously do this for fairly cheap cause I thought I already have most of what I need as far as hardware and software. My idea was to use this comp for a home server (3 other comps in the house) to dish out all of the word and text doc to a sh** load of pics and small home video clips, and of course the mp3's. I have a used vrm I got for $5 here in town, some techy said it would work in almost any dell optiplex gx300 sytem and the part # on it is hp p/n 0950-2847 hope it will work but don't know how to tell (just 5 bucks though). I have inspected the mb very closely and as far dip switch settings go there isnt any besides your basic bios clear and such, please inform on what hardware setup Or motherboard changes I need to do cause I built basic systems but don't have a clue from here and my bios is currently updated to the most current revision of a-10 thanks

hi,

about the unstallation issues:
http://support.ap.dell.com/docs/Systems/opgx300/en/ug/process.htm  for Adding a Second Microprocessor
http://support.ap.dell.com/docs/Systems/opgx300/en/sm/remmt.htm#heat_sink_assy  look for Figure 25. Microprocessor Removal
http://support.ap.dell.com/docs/Systems/opgx300/en/ug/inside.htm for jumper settings etc.
http://support.ap.dell.com/docs/Systems/opgx300/en/ug/install.htm for Installing Upgrades
http://docs.us.dell.com/support/edocs/systems/opgx300/en/ug/messages.htm for Messages and Codes

regarding the VRM you should have ,i found theese infos:
"..
NOTICE: Systems with two processors installed must have a voltage regulator module (VRM) installed in the VRM socket on the system board (see Figure 22).
.."(as http://support.ap.dell.com/docs/Systems/opgx300/en/sm/remmt.htm )

the hp p/n 0950-2847:
it must be a VOLTAGE REGULATOR MODULE-NS LH4/LXr 8000
http://www.intekusa.com/0950-2847.htm
http://www.multicom-cs.com/0950-2847.html
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5766086645 you could ask a question to kaylas-grandpa if it will work with your gx300,you still have the time...
so i'm not 100% sure if it will work but i found a dell's vrm for your optiplex gx300:
http://www.acsparts.com/7649D-Dell.html

----------------------
regarding the slot -t slotkets-just forget about it ,it's not a relevant issue.

If he doesn't have the VRM, it will probably be a killer, because they are just about impossible to get.  If he has that, then probably it's just a matter of replacing the dummy board with the 2nd CPU and setting some jumpers.

rhequiemCommented:
Yep. Beyond suggesting maybe a little more RAM, I'd try popping that 2nd cpu in and giving it a whirl. If it doesnt work, you can always run the server with the one processor, since you meet the minimum system requirements. Good luck :)

ebaker05Author Commented:
Okay well I do appreciate it again, and I could not find anything else about setting jumpers especially for 2nd cpu apps on the dell sites, so I tried it and after putting it al back together and starting it, it just sits there running and never attempts to boot and doesn't display a thing. So i guess it could be the wrong vrm I've submitted a question to gramps on ebay like u suggested but no response yet, If it is just a matter of getting the right vrm I will probably continue my search for it at a resonable price. thanks again and any other suggestions are appreciated.

if there are any jumper settings you all can see that I might have over looked please inform

hi ebaker05,
wait a while if you do receive though an answer from this ebayer,it's just a matter of three days/but, beware of:ebayers are mostly laymen and reselers/,,,

as i researched your needed and very vrm it's from the dell's house :dell 7649d,and indeed for running the dual cpu combination you do need the voltage adaptor,,,

if i find something more regarding the two kind of adapters(settings,better prices) i'll post it straight away to you.


till later

Indeed I received an answer here is what it says "if it is a 40 pin then yes........ I pride myself on trying as many different machines but I have never had yours  send picture of the vrm spot I will tell you
 
Mike


 This whole way of determining the correct vrm by the amount of pins seems very unlikely to me.    I have attempted ordering the dell part#749d and so far the two places that mwnnj posted say it's not currently in stock, however thanks for all of your efforts.
