CPU-Z Read on Memory. What am I looking at?

I recently upgraded the memory in an MSI-6547 socket 478 from 256 megs of PC2100 to 2 Gigs of Kingston PC2700, CAS Latency 2.5, 2.5v.

The motherboard can take a total of 3 gigs but was not designed for dual channel. The memory installed fine and the system immediately recognized.

Here is where I could use some insight. The BIOS shows the voltage at 2.6v but CPU-Z shows both sticks at 2.5v which they are designed for.

Also, CPU-Z shows stick 1 at frequency 133MHz but the second stick at 166MHz.

The CAS for stick 1 is 2-3-3-6-11 and the second stick at 2.5-3-3-7-11

I don't know why there are descrepencies. Anything I need to be concerned with? This isn't my system so I want to make sure it will be done right.
 
In CPU-Z the Memory Tab shows what all sticks are running at together. The SPD tab shows what each stick is rated for.
 
Thanks for the reply. I understand the what the readout is telling me but what I am wanting to know if the descrepencies between stick 1 and stick 2 is a normal thing or should I attempt to bring them to the same read-out.

Your board cant run 2 sticks at different timing and voltage at the same time.

The Memory Tab shows what both stick are running at.

The SPD tab shows what each stick SPD/rated speed and timing.

What ever speed/timing thats listed under the Memory Tab is what both sticks are running at.
 
It stands for "Serial Presence Detect" ... words that I half-way understand.

Why can't it just be something more simple and clear, I don't know.

there is no discrepancy except that the two sticks are different in the speeds that they are meant to run at. the computer sees that one stick is slower and automatically slows the other stick down to match speeds, since they cannot run at different speeds.
 
Maybe I am not clear or I am truly thick headed. Both the new sticks installed are the same Kingston PC2700 CAS# 2.5, 2.5 volt. Yet one's frequency is lower than the other and one's timings are different than the other. The old PC2100 (DDR266) was uninstalled so that can't bring down the two new sticks.

Again, these are the same type of RAM not two different sticks with one manufacturered with higher timing frequencies than the other. So why does CPU-Z show stick one as downclocking when it is no different than stick two?

Oh, so your saying that they are a matched pair, but under the SPD setting it shows they have different timing and voltage as default?
 
Dont know if you already have. Even though they were sent to you as a set, if they have stickers on them check out the part number and make sure they match.
