Hi All!
I've run into a problem with upgrading my notebook's memory, and I would like to ask for the community's help.
This is an HP Compaq 2230s laptop with the Intel GL40 Chipset and a Celeron T1600 cpu.
The story:
The computer originally came with a 1GB Samsung module and another empty slot. I checked on the website of HP and Intel, and came to the conclusion that this laptop supports PC6400 DDR2 ram. So I bought a 2GB CSX branded module. After installing it the computer will not boot, there is a blank screen and the caps lock led blinks three times then repeats this pattern. According to HP this means a memory problem during P.O.S.T. I've tried all possible combinations with the slots, taking out the original ram module, leaving it in etc, the result is always the same.
Now here is the confusing part: HP's site claims this laptop supports 800mhz ram. However the service manual also found on the HP site says it can take 667mhz ram. I've checked the original Samsung module itself, and the sticker on it says PC2-6400s-666.
However if I check with CPU-Z under the memory tab it says this:
DRAM Frequency: 332.5 Mhz
If in CPU-Z I go to the SPD tab it says Max Bandwidth: PC2-6400 (400Mhz).
So the question is, could my problem be because I bought the wrong RAM? I'm leaning towards the new ram module being faulty because as far as I know DDR2 ram is backwards compatible so an 800mhz module would still run at the lower frequency in a laptop supporting 667mhz, but I'm not sure and would like to know what others here think.
Thank you very much in Advance!
Tom
