Hi. I just purchased some 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

Front Side Bus (FSB) Speed : 800 MHz
L2 Cache Size : 512 KBytes Stepping : D1
Trace Width : 0.13
Microcode : 21h
Instruction Sets : MMX, SSE, SSE2

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. Then 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.

I tried to talk with the store, and this is the answer I got - nevermind the spelling ! :-))))
Dear Sir,

This kind of problem is well known on any computer like Dell, HP or any brand name computer which used very poor component, or no name component, and in all case itís a problem with the Bios. You have maybe just to update your Bios, it a bios update exist. But if your computer works with the 4 slot loaded, thatís mean thatís everythingís is fine and donít read the Bios, because on this kind of computer the bios doesnít reflect the reality.

Your memory come directly from OCZ in California like all our memory every single day.

Might it really be the BIOS which is not reporting the correct speed ????

Thank you.


PS. There is NO Bios update on Dell's site.

Do you know what the CAS latencies are for each pair of modules?

I believe all 4 modules have to match. This IS a known issue with certain Dell systems but you should be able to get round it by making sure the CAS latencies (as well as speed) are identical for every ram modules. When the cas latencies are mismatched, the system decreases the overall speed of the ram to compensate for the mismatch.
