Can you access the BIOS? If it is possible, then try putting just the new one in, then go into the BIOS and manually set the DRAM frequency and the timings.
Thank you for your answer ShakedG...
Can you access the BIOS?
>> Yes I can.
If it is possible, then try putting just the new one in, then go into the BIOS and manually set the DRAM frequency and the timings.
>> I tried that too. The automatic values that are represented in BIOS for RAM are:
DRAM Frequency -> Haven't found it where I could change it in BIOS, but will look into it more....
RAS# to CAS# Delay (tRCD) 9
RAS# Precharge (tRP) 8
Cycle Time (tRAS) 8
Cycle Time (tRAS) 20
Which is weird (I mean the combination or am I wrong ?!). If you check the images it says different combinations, for example 9-9-9-24 (which I tried by the way with no luck), you are more than free to provide further suggestions that I can try out please. DRAM I haven't found nowhere to check maybe it could be in some POWER options in BIOS, have to look little more in, If I find it should I set it to higher or lower Mhz?!
