1. The BOXED version of
the Pentium 4 CPU comes with the CPU chip mounted on its own 423-pin circuit board, a Heatsink Assembly (including 3-wire controllable fan), a syringe
containing heatsink compound, the warranty and installation instructions,
and an "Intel Inside" sticker. The heatsink compound is injected onto the
top of the CPU, and is designed to enhance the transfer heat to the
heatsink assembly.

2. The motherboard
requirements are different for a P4 as opposed to a P3 CPU. The Intel
D850GB
motherboard has four additional mounts for the CPU heatsink assembly and
two additional power supply connections. The heatsink mounts are supplied
with the Intel D850GB Boxed Motherboard.

3. This picture shows the four extra heatsink standoffs required of the case assembly to install the Pentium 4 heatsink mounts for an Intel D850GB Motherboard. |

4. This photo shows the above image with the new items highlighted. They include the new heatsink assembly mounts, the ATX12V power connector, and the auxiliary power connector. |

5. Memory used with Intel
D850GB motherboards, designed for the P4 CPU, must be installed in
pairs that are matched in size, speed, and density. There are 4 RIMM
sockets into which you can install from 128MB (minimum) to 2GB (maximum)
RDRAM. For example, to obtain 256MB of RDRAM, you must install a pair of 128MB RDRAM memory RIMM modules into each of the first two slots. The remaining two slots, given that they are not populated, must have a pair of "Continuity RIMMs (C-RIMMs)" installed to complete the memory connections. If any of the memory slots are not populated, POST will not complete. When you purchase the Intel D850GB boxed motherboard, it includes a pair of C-RIMMs.

6. This picture shows the
installation of the two Heat Sink Assembly mounts on the Intel D850GB
Motherboard. There is one mount on each side of the CPU socket to
facilitate mounting the Heat Sink Assembly included with the boxed
Intel P4 CPU. The Case you purchase for your P4 must include threaded
holes for the Heat Sink Assembly Mount standoffs. Older cases, designed for
P3 CPU motherboards with its ATX form factor, do NOT include these
additional 4 holes.

8. This photo shows the Intel P4 CPU and its circuit board mounted in the Intel D850GB 423-pin CPU socket. The heat sink compound, included with the boxed Intel P4 CPU, is deposited on top of the CPU chip itself. Note the CPU circuit board alignment mark (a small triangle) located on the upper left corner of the CPU circuit board. |

10. The Intel D850GB
motherboard, using the 850 Chipset, uses RIMM modules of RDRAM (The RIMM module contains the
RAMBUS RAM). This memory is available in either a PC600 or PC800 module
format. We use the PC800 RDRAM to accommodate the 400MHz System Bus
with no problems.

11. This is a photo of
the backside of the RIMM module. Pay attention to the connector key slots
as you install the memory into the motherboard RIMM slots.
|
|
12. This photo shows the installed RDRAM RIMM modules, and also shows the Continuity RIMM modules (C-RIMM) installed in the 3rd and 4th RIMM memory slots. |
|
13. Here's another picture of the RIMM and C-RIMM installations. |
|
14. All the parts are installed. The motherboard is now ready to mount on the case chassis. |
