No that memory is not compatible. The Precision 350 uses memory called RDRAM aka RAMBUS.

Here are the speeds and sizes that are supported.

Memory modules supported PC800-40: 64-, 128-, 256-, 512-MB, non-ECC or ECC

PC1066-32P: 128-, 256-, 512-MB, ECC and 64-, 128-
,256-,512-MB, non-ECC

Minimum memory PC800-40: 128 MB non-ECC and ECC
PC1066-32P: 128 MB non-ECC and 256 MB ECC

Maximum memory PC800-40: 2 GB non-ECC and ECC
PC1066-32P: 1.5 GB non-ECC and ECC

2GB.

The Intel Desktop Board D850GB has four RIMM sockets (two sockets for each channel) and supports the following memory features:

Single- or double-sided RIMM configurations
Maximum of 32 Direct Rambus devices per channel
Total system memory configurations from 128 MB (minimum) to 2 GB (maximum) utilizing 128/144 Mbit or 256/288 Mbit technology PC600 or PC800 compliant RDRAM
Serial Presence Detect (SPD) based configuration for optimal memory operation
Suspend to RAM support
ECC and non-ECC support

When installing memory, note the following:

The four RIMM sockets are grouped into two banks:
Bank 0 (labeled on the board as RIMM1 and RIMM2)
Bank 1 (labeled on the board as RIMM3 and RIMM4)
Bank 0 must be populated first ensuring that the RDRAM installed in RIMM1 and RIMM2 is identical in speed, size, and density. For example, the minimum system configuration would use two 64 MB RIMM modules of PC600 or PC800 RDRAM.
If the desired memory configuration has been achieved by populating Bank 0, then Bank 1 should be filled with two Continuity RIMMs.
If memory is to be installed in Bank 1, the RIMM modules installed in RIMM3 and RIMM4 must be identical in size and density to each other, and match the speed of the RIMM modules in Bank 0. The RIMM modules do not, however, need to match those in Bank 0 in size and density. For example, if Bank 0 has two 128 MB RIMMs of PC800 RDRAM, Bank 1 would require PC800 RDRAM also, however, any other supported RIMM modules such as 64 MB or 192 MB could be used.
If ECC functionality is required, all installed RIMM modules must be ECC-compliant.

It sounds like like you have multiple issues. When all memory slots are filled with 256 sticks the computer boots but only sees 256 MB instead of 1 gig.
When you install the Crimms it won't boot at all.
You may have an open circuit on one of the Crimms.
As for the computer seeing only 256 MB you may have a bad memory slot on the motherboard.
Here's a link regarding Direct Rambus DRAM or DRDRAM (sometimes just called Rambus DRAM or RDRAM: http://en.wikipedia.org/wiki/RDRAM

HELLO Paul

When installing memory modules in the system board sockets and not using the optional memory riser boards, observe the following guidelines:

• Each memory socket on the system board must be occupied either by a RIMM or a CRIMM.
  
  
• Memory sockets must be upgraded in matched pairs. In other words, two sockets in a pair must contain modules of identical capacity, number of components, and speed. See "System Board Memory Components" to identify pairs of sockets.
  
  
• Mixed pairs of ECC and non-ECC modules all function as non-ECC.
  
  
• Be sure to install a RIMM in socket 1 first (closest to the processor) before installing modules in the other sockets.
  
  
• The system board supports PC600 and PC800 memory modules.

I hate to be the bearer of bad news, so don't 'Shoot the Messenger'!

The Dell Dimension 8200 Desktop PC uses RDRAM ram memory.
VERY expensive stuff!

Supporting Data:
This is Dell Support, Manuals, and the Dimension 8200 Service Manual,

http://support.dell.com/support/edocs/systems/dim8200/

Scroll down the list to the heading - Specifications, and left-click on it.

Scroll the page down until you come to the heading - Memory
Now look at the first subheading - Architecture
RDRAM

You have 4 ram memory slots. (memory connectors)

EACH, ram memory slot can support up to a Maximum amount, of 512MB. (512 MegaBytes)

TOTAL Maximum Amount for your computer is 2GB. (Not shouting)

1024MB = 1GB. (1024 MegaBytes = 1 GigaByte)

The type of Rdram ram memory is PC800, and it is Non-ECC.

(Error Correcting Control, or also stated as Error Correcting Code.
Used mostly for Server computers. Your computer does not use ECC ram memory)

In My Humble Opinion, (And again, don't shoot the messenger), it would be better money spent to buy a decent affordable computer, than it would be to upgrade the ram memory in this computer.

This statement is based upon the fact that the Dell Dimension 8200 ships with 128MB's of ram memory.
(Makes it a pretty slow computer. Rdram or not)

The average cost to install, for example, 1GB of ram memory is OUTLANDISH! (Not shouting)

Example 2:

For about another $100 you can buy a pretty decent new desktop computer, that will run the one you have in circles.

Just my thoughts.

Hello,
for the memory upgrade, your system used RDRAM RIMMS.
it supports the following memory modules (which must be installed in pairs).

and as for opening the case, you there should just be ~2 screws on the side panel away from the motherboard ports that you can remove and it will slide off, or there might be 1 or 2 thumb screws.

64MB Module 64MBx16, 800MHz PC800, 184p RIMM, RDRAM, 45ns, 2.5v PC800-Kit-136 128MB Module 128MBx16, 800MHz PC800, 184p RIMM, RDRAM, 45ns, 2.5v PC800-Kit-079 512 MB Kit 256MBx16, 800MHz PC800, 184p RIMM, RDRAM, 45ns, 2.5v PC800-Kit-081 64MB ECC Module 64MBx18, 800MHz PC800, 184p RIMM, ECC, RDRAM, 45ns, 2.5v PC800-Kit-134 128MB ECC Module 128MBx18, 800MHz PC800, 184p RIMM, ECC, RDRAM, 45ns, 2.5v PC800-Kit-080 512 MB ECC Kit 256MBx18, 800MHz PC800, 184p RIMM, ECC, RDRAM, 45ns, 2.5v PC800-Kit-082

Often simply disconnecting the power cable, holding power button for 15 seconds, release power button, plug back in will work

Otherwise remove CMOS battery and perform above operation

Hope it works

check ther is 4 ram bank and if then fix ram after left 1 bank.then check .
there is also check frequency same of both ram.
