Computer newbies: Upgrading RAM on Dell Dimension 8200
You indicated RIMMs must be same speed and capacity .....
by VAPCMD - 2/13/07 5:56 PM In reply to: Installing RIMMs by Darton FuryI'd agree on should be same speed but where does it specify the capacity must be same for four RIMMs?
Here's some info from the Dell website on the 8200
Memory
Architecture RDRAM
Memory connectors four
Memory capacities 64-, 128-, 256-, and 512-MB non-ECC RDRAM
Minimum memory 128 MB
Maximum memory 2 GB with Microsoft® Windows® 2000 and Windows XP;
512 MB with Windows Millennium Edition (Me)
Memory type PC800 (non-ECC)
Memory speed 40 ns or faster
BIOS address F8000h
Had no problems upgrading identically equipped Dell
by MikeyD215 - 2/16/07 3:30 AM In reply to: Upgrading RAM on Dell Dimension 8200 by bluecomet390I added 512 MB to the 256 MB originally installed at the factory several years ago without any problems whatsover. The additional memory was immediately recognized. Although I had already checked for a BIOS upgrade and had already upgraded to BIOS A9 earlier, the only other thing I did was follow the directions in the Dell Solutions Guide. As I recall, when I bought the memory (at Computer Builders Warehouse) I did take one of the old "sticks" with me to show them what was already there and the fellow who waited on me told me that the modules he was handing me would be the ones to install.
I agree call and by Dell
by trashcrash - 2/16/07 5:44 AM In reply to: Had no problems upgrading identically equipped Dell by MikeyD215I just upgraded the memory in a Dell Dimension 2400 with a gig of ram. After research and reading of problems with other memory I called Dell. Now it go's zoom zoom zoom.
OR,,,,,Go To CRUCIAL's website.
by JR - 2/16/07 6:39 AM In reply to: I agree call and by Dell by trashcrashCrucial has a simple memory advisor which tells you what you need, also a system scanner that tells you exactly what is already in your system and is much cheaper than Dell. I have bought memory through crucial.com for 6 years now for who knows how many computers that I have built or upgraded, including my own dell dimension 4200 which I purchased new in 2002. Never a problem!And they have a lifetime warranty.
Go to their site and try it!

by Barrister33 - 2/20/07 8:05 AM In reply to: OR,,,,,Go To CRUCIAL's website. by JRI had a devil of a time upgrading my Dell 8200 from 512 RD Ram to 1 Gig, and Dell was of absolutely no help whatsoever. I decided to run the Crucial advisor, purchase the RAM form them and cross my fingers. It worked perfectly.
Dell = evil
by emmiii31771 - 2/16/07 7:32 AM In reply to: Had no problems upgrading identically equipped Dell by MikeyD215Every time I have called dell I have had nothing but trouble. Everything that I have eal with dell memory, if they are pair, is that slot 1&3 & slot 2&4 are the ones that are paired. and I agree with the person above let it config
Ram for my 8200
by MarkTheSpot - 2/17/07 1:20 AM In reply to: Dell = evil by emmiii31771I added 512 mb (2 x 256) to my Dell 8200 years ago. I used the program CPU-Z to check the type of ram already in the computer.
PC800 (400 MHz)
Samsung part number for slot 1 & 2: MR16R 1628AF0-CM8 (2002)
Slot 3 & 4: MR16R 1628EG0-CM8 (2004)
Can I change my RDRAM from 800-40 to 800-45?
by craw4dm - 3/3/07 4:06 PM In reply to: Ram for my 8200 by MarkTheSpotI too am trying you add more RAM to my 8200. The two 256's in it now end w/ 800-40. I have access to four 256's, but they end in 800-45. How do I know if I can change all four slots over to these new 800-45's and have no problem what so ever?
Uh oh
by towardthesea - 6/26/07 7:19 AM In reply to: Can I change my RDRAM from 800-40 to 800-45? by craw4dmThis thread has made me a little paranoid. 
I have an 8250 that came with 256 MBs of 1066 RDRAM, I believe in a pair of 128 MB modules. Obviously, it's running pretty slow these days.
I made the mistake of shopping for RAM on eBay without doing sufficient research. I bought 1GB (2 x 512 MB) Samsung Rambus 800-45ns ECC, which also came with 256 MB (2 x 128 MB) Samsung Rambus RDRAM PC800-40ns. They're enroute now. I plan to pull my existing 1066s and put in these two pairs of 800s.
After reading this thread and some other information, I have several concerns:
1) In the manual for my 8250, it says RDRAM should be 40ns or faster. Will the 45ns modules even work in my system? Can they harm it?
2) I see now that 1066 RDRAM is superior to 800. Given this and the 45ns caveat, will I actually be sacrificing more speed than I'm adding by increasing the RAM to +1 gig?
3) Will the 40ns modules work with the 45ns modules? I've seen conflicting information on this. My understanding is that all the memory will be recognized, but at the slower 45ns speed.
4) The manual says the RDRAM needs to be non-ECC. I know the 512 modules ARE ECC. Not sure about the 128 modules.
Any help you guys could provide would be much appreciated!
Uh oh...

1.) Some older models would check the speed and refuse to boot if it's not recognized, but it sounds like it's a recommendation and not a requirement with the 8250. Thus, it should be fine.
2.) Speed vs capacity. In this case it's the difference between 256MB of 1600MB/s RAM and 1GB of 2133MB/s RAM. Unless you're using relatively little RAM at any given time with a demand for the highest response time I'd rather have the 1GB at my disposal with a little less speed.
3.) Yes, they should work together harmoniously provided #1 holds true.
4.) And there lies the problem. Some have reported being able to use ECC RAM in a computer that does not support it by running it in a non-ECC mode, but I wouldn't get my hopes up...Dell specified non-ECC for a reason.
Personally, I'd check with the seller to see if you can send it back for a refund, less S&H. If not you could try it out, but most likely you'll be reselling it on Ebay before long.

Samsung 800-45 no not work on 8200
by EmmEmmBerlin - 1/31/08 3:38 AM In reply to: Uh oh... by John.Wilkinson
Hey,
Pre-Installed on my 8200 System are 2x 256MB 800-40. Removing those and REPLACING the two by Samsung 2x256MB 800-45 leads to the BIOS error message:
Used RDRAM incompatible, please install modules with 40ns or faster.
Since they are faster I am not sure what to do. Bios is up-to-date.
You have any ideas?
(NT) In this case, 40ns is faster than 45ns

by johnnyg - 2/29/08 1:24 AM In reply to: Uh oh... by John.Wilkinson
hi
I have similar problem. I rather stupidly looked at 45ns rimms being faster than 40ns when I decided to by 1gb of ram from ebay.
The Dell 8250 needs 40ns or faster. Clearly now I understand that 45ns is slower than 40ns!!
The PC does not boot, just returns the message that "incompatible memory in Rimm slots, replace with 40ns or faster".
(This I think has been mentioned elsewhere in this thread)
Does anyone have a solution to force the 8250 to accept 45ns rimms?
Everything else about the Rimm I have is compatible(non ecc, PC800 etc etc)
The BIOS setup has no menu for Ram options....maybe there a BIOS update which allows this?
Thanks to all and hoping there is a solution
(NT) Why nog buy compatible RAM?

In reply to: 45ns Rimm in Dell 8250 by johnnyg
45ns in place of 40ns
by johnnyg - 2/29/08 2:00 AM In reply to: (NT) Why nog buy compatible RAM? by Kees Bakker
Hi
Yeah thats a solution. However I have the 45ns rimms already at a good price.
To resell back on ebay is a hassle and costs
If there was a known way to make the 45ns rimms work then thought that would be best
Cheers
