Hi. I just purchased 512MB of new memory today - OCZ DUAL DDR PC-3200
Performance Series Rev. 3 Dual Channel, 512MB, PC400. I installed it on
my Dell Dimension 4600 (which already had 512M of RAM Dual Channel).
Here is the report on my computer BEFORE installing the memory:
__________________________________________________ _________________________________________
This PC currently has 512 MB of memory installed, and supports a
maximum of 4096 MB. There are 4 memory slots on the motherboard, and 2
of them are empty. The maximum memory module supported by this system
is 1024 megabytes. You can add up to 2 PC3200 DDR DIMM modules (choose
from available sizes below). To maintain consistent memory performance,
select memory with a CAS Latency (CL) of 3.0 clocks or lower.
Slot 1: Kingston 256MB PC3200 DDR K
Slot 2: Kingston 256MB PC3200 DDR K
Slot 3: EMPTY
Slot 4: EMPTY
Total RAM Installed : 512MB
Type : DDR DIMM PC3200
Used RAM Slots: 2 of 4
Memory Bus Frequency: 199 MHz
Memory Timings: 3.0-3-3-8
After installing the memory, the system correctly reported a total of
1GB of RAM, but at a speed of 266Mhz INSTEAD OF 400. I took the new
memory out, I rebooted, and the speed went back again to 400Mhz. I
re-installed it, I rebooted again, and the speed went down again to 266
Mhz.

Did you enter the BIOS and attempt to change the memory bus from 133
(266/2) to 200 (400/2)? Why did you buy different RAM in the first
place? Also, why did you spend so much money on OCZ Performance memory
when your system is unlikely to boot below 3-3-3-8? (given that's
probably the standard timimgs of your existing RAM)
I can't !!! Remember, this is a DELL BIOS, and it's VERY skinny ! These
fields are read only, and in the memory section I can only change the AGP
aperture, which is currently at 128, I think.....
Different RAM ? Which RAM should I have bought ? It is Dual Channel, it is
DDR, it is 3200.... what else ? I don't know what else to look for ! I
assumed that's all I need.
BTW, I assume that the computer takes for these timings the lowest common
denominator (in our case, the "largest" timings). Is that right ?
I also tried the following - I took out the original memory and I installed
ONLY the OCZ memory - the system reported 333 Mhz. I switched back to the
original memory, and my BIOS immediately reported 400Mhz, correct. Could it
be that everything is fine, but the BIOS gets somehow confused ? I don't
really think so, but... I have no other idea, assuming that the stiks have
not been mis-labeled by OCZ...
Thank you for your posting !

to analyse your RAM and see what speeds it really runs at use CPU-Z (google
for it).
If your bios auto-detects RAM and adjusts accordingly with no override -
maybe theres a jumper setting on the motherboard that'll allow you to force
the full 400mhz.
Check your motherboard manual.
