I have ASUS Laptop Series K52jc with 4G memory and running at 2.4Ghz. I have attempted to upgrade the memory to 8g. I bought 2 x 4g sticks of "4GB PC3L 12800 CL11 204 pin SODIMM"
and added them, no success. I then tried 2 x "4G of 4GB 10600 CL9 204 pin SODIMM" and they failed. on each account reverting back to the origonal 2G sticks, the computer rebooted.
I read through some of your literature on memory and followed up by downloading and running CPI_Z.
From the CPU_Z screen and under SPD I see that the current memory is PC3_10700(667)mhz and under that in column JEDC#4, freq is 666Mhz and CASLatency is 9.0, RAS to CAS 9, and RAS Precharge is 9.
Being confused some what, the question is? Why would the second set of chips fail even with a Latency of 9 and does the latency follow the frequency hense the PC3L set having a higher latency of CL11. Does the CPU / Bios adjust to latency of the supporting chips.
Thanks.
