Hi Alan,
System----4CPU 2.53GHz 2.52GHz.256MB of RAM
Yes, we did put the 2 new ones in the 1 & 2 slot, leaving the dummies in 3 & 4.
I did contact the seller & he is very nice, told me to send these back & he'll send 2 that go with this. So it was an unwanted glitch but I've waited this long, another week won't kill me :-) and he's excellent on shipping too, I had this memory in like 2 days. Not as good as having one of you list guys living in my neighborhood but not terrible either, lol

Hi Jeanne,
It is the correct memory (in theory) for your Dell 8200, according to the advertisement as well.
There's little difference between PC800-45ns and PC800-40ns. They should both work in your machine,
depending on your processor (see below).
I'm wondering about a few things:
Can you tell me your processor (CPU) speed? You'll see it in System in the Control Panel. I just
noticed this little warning in Product description if you click on 'Return to product information'
in the advertisement:
"Dell Dimension 8200 8100 PC800-45 RDRAM 1GB (2X512MB) Rambus RIMM will work with CPU 2.2GHz or
lower."
This may be significant if you have a stronger processor. See one of the reviews for this product by
somebody called Weevil:
"Product is performing fine, really sped up processing on home desktop computer. One issue though, I
didn't know that the speed (40ns versus 45ns) was dependent on processor speed, so had to send back
the first pair and pay to have the second set shipped. Not quite such a good deal after that, but
the product works great."

Did you follow the correct procedure? - i.e.
Replace the 2x 128 MB modules with the 2x 512 MB modules in the exact same RIMM slots?
Also, did you leave the dummy (continuity) modules in place?
Did they click solidly into place when you inserted them so that the white notches go back to the
upright position?
The thing is this RDRAM has very specific requirements. If you look at the Dell manual for adding
memory for this machine, you'll see that the dummy modules will only function in RIMMS 3 and 4. The
normal 2x 512 MB modules go in RIMMS 1 and 2 nearest the processor.
http://support. euro.dell. com/support/ edocs/systems/ dim8200/replace. htm#1101964
Is there any chance that you took all the modules out and maybe put the continuity modules back in
RIMMS 1 and 2 by mistake?
Or that you left the older 128 MB modules in there along with the new ones? As I said before this
will also lead to problems since your old 128 MB modules are non-ECC and these new ones are ECC.
They don't like each other. The only configuration that will probably work at the moment is the 2x
512 MB in RIMMS 1 and 2 and the dummy modules in RIMMS 3 and 4.
Coincidentally I have a Dell 8200 and a Dell 8250 sitting here that the owners put out to pasture.
They're still working. The 8200 has 4x Kingston 128 MB PC800-45ns and the 8250 has 4x 256 MB
PC800-40ns (two different brands). I just swapped both sets of modules and they work fine in both
machines - the Dell 8200 has a 1.8 Ghz. processor and the 8250 actually has a 2.4 Ghz. processor.
The PC800-45ns still worked in there.
If the above doesn't help, I'd contact the seller since they specified a years's guarantee in their
advertisement. They should replace them if they still don't work after any advice they may give
themselves. Although there's not much you can try. It either works or it doesn't if you have them in
the correct RIMM slots.
Ah, the joys of RDRAM......
Alan

> I think you may have a couple of numbers wrong there Jeanne - it's 128 MB in the 1st line and probably ....CM8 in the second line instead of CMB. This is 128 MB non-ECC Samsung memory, so they won't mix with those 'used' modules we were looking at on Amazon, which are all ECC. But that's no big deal. If you go for 2x 512 MB and you have 1024 MB total, you won't notice much difference in speed even if you were able to mix them with the 2x 128 MB that you have now. Your current modules probably look like this:

I think if you go for the used 2x 512 MB and install those instead of the 128 MB modules, you'll be fine. It's a huge increase in performance over what you have now. Should be fun. The RIMM modules advertised are specifically for your kind of Dell and they have a good warranty, so there's little risk. This type of memory is usually rock solid. I never had a problem upgrading Dell 8100s or 8200s when they were popular.

All the RAM slots need to be filled on a RDRAM system. Just replace the two 128 MB modules with the two 512 MB ones, leave the dummies in place and take it from there.If you decide to go for the 2x 512 MB kit, it might be a good idea to mail or call the seller first as I see that each seller only has one kit of used available. Just to make sure it's still in stock before you place your order and pay for it.

Hi Alan,
Yes, I had printed out all of the info you gave me....it is very good to have!
How much.....as much as I can :-) but still have things running right.
Old & new.....what are your thoughts? I want to do this as painlessly as possible so is it a good idea to mix old & new or should I go with all new?
Of the choices you gave for 2x 512 MB, is that in addition to what I have or instead of?
I did look at one of mine & on it is......
1st line.....Korea 0234h 126MB/4
2nd line....MR16R1624AF O-CMB 800-40 011
That's on the sticker. I see no mention of ECC?
Thanks for your help!

Hi Jeanne,

So you're finally taking the plunge... I remember giving you info about your RDRAM in June last year. You had 256 MB (2x 128 MB) of memory at the time and I assume it hasn't changed. The question is - how much do you want to add? And do you want to combine the old with new memory? I have no idea of your budget but I wouldn't install more than 2x 512 MB, even though you can go up
to 2 GB. The cost of this type of memory just outweighs the value of the computer.
>
You're on the right page for PC800 for your Dell. You'll need a kit - two identical modules. I used to buy these used since they were cheaper and they're just as good as new. On Amazon most of the used sellers give some kind of guarantee as well. A new 1 GB kit costs around $65 and a used kit costs about $40. New is horribly expensive compared to newer DDR type memory but that's how it is
with RDRAM. It's scarce. I'd recommend installing 1 GB to enjoy a substantial difference in speed. Personally I'd go for used from a reliable seller in this case. If you want to go for 2x 512 MB, this looks good:
http://www.amazon. com/gp/offer- listing/B000J658 CU/ref=dp_ olp_used? ie=UTF8&m= A2WRERIMEQIKWL&condition= used
- 97% positive ratings and 1 year warranty.
or either of these for $40:
http://www.amazon. com/gp/product/ B000J658CU/ ref=ox_sc_ act_title_ 1?ie=UTF8& m=A21B2BUK2Z8B72
http://www.amazon. com/gp/product/ B000J658CU/ ref=ox_sc_ act_title_ 4?ie=UTF8& m=A2IXUIOVMBEVB9
>
If you just want to increase to 512 MB (2x256 MB), this is extremely cheap at $15 from
>
Link-Tronics:
http://www.amazon. com/gp/product/ B001AQYO96/ ref=ox_sc_ act_title_ 3?ie=UTF8& m=A2WRERIMEQIKWL
Then again, you could buy 4 of these 256 MB modules since you have 4 slots on the motherboard.
>
Then you'd be getting 1 GB for $30. That's a very good deal for this type of memory..... It makes no difference if you use 2 x 512 MB or 4 x 256 MB. Just slightly more risk with the 4 x256 MB if one of the modules is defective, since they work in conjunction.
>
If you were thinking of combining these with your current modules, beware. Looking at the photos, these are nearly all ECC modules and they will work fine in your 8200 even though the Dell documentation says it should be non-ECC. What won't work is if you have non-ECC in there at the moment and you try to combine it with ECC. ECC and non-ECC don't mix. You'd have to have a look at the labels on the modules in your PC if you're thinking of combining with the old memory. It
tells you there. If they're ECC, there should be no problem combining. Although 256 MB is so little, I wouldn't take this much into account when you're buying new modules.

Can you look & tell me which one is the right one for my set up? With so many choices, I want to make sure I get the right ones for my computer.
