Hi,
My Pc Specs
Gigabyte G41M Combo Mobo
Intel Core 2 duo E7400 2.8 Ghz
DDR2 2 GB ramI am replacing this ram with 4 Gb G skill 1333 Mhz RipjawsX Ram.
But when I install it, the PC does not start and Mobo starts beeping continuously. It is working fine with DDR2 ram.The mobo supports 1066 Mhz and 1333 Mhz(by overclocking) DDR3 Ram.
I bought this ram thinking it will automatically downclock to 1033 Mhz but it hasn't.How can I make it work?
"But when I install it, the PC does not start and Mobo starts beeping continuously" The beeping is an indication that the RAM isn't fully seated in the slots. Make sure it locks in on both ends.
And if you have no plans to overclock the CPU, you should be running the RAM as DDR3-1066 @ 533MHz frequency. Running DDR3-1333 @ 667MHz without overclocking the CPU to 333MHz frequency will throw off the ideal CPU:DRAM frequency ratio of 1:2. Instead, it will be 2:5 & you'll take a performance hit.
Your board specs states the board uses DDR2. You can't use DDR3 in that board. You may fry things if you are attempting that. See the link below. Maybe you just made a typo with the DDR3. http://www.gigabyte.com/products/pr...

But that's not the OP's m/b. His does support both DDR2 or DDR3 memory. And it should support the memory mentioned, so I guess that #1 is correct. Either that or (s)he hasn't removed the DDR2 memory first.
OK then, I thought the whole series would be basically the same as the board I linked. I haven't noticed any boards supporting two types of RAM for a few years. Evidently they are still made.
Thanks for the Quick reply! Mr Riider,
I don't want to overclock, I just wanted it to work @1066 Mhz when I bought it.
I thought it would underclock automatically.I don't know what to change in the bios.
These are the settingsRobust Graphics Booster Auto
CPU Clock Ratio 10x
Fine CPU clock Ratio [0.5]
CPU Frequency 2.80 GHz(266*10.5)Clock Chip Control
CPU Host Clock Control disabled
CPU Host Frequency 266
PCI Express Frequency AutoDRAM Performance Control
Performance Enhance Standard
MCH Frequency Latch Auto
System Memory Multiplier SPD Auto
Memory Frequency 800 800
DRAM Timing Schedule SPD AutoThe Bold ones are unclickable.
What all I have to change? I don't know nothing about these settings.
Help Greatly appreciated
Thanks
