I have a Gigabyte GA-P35C-DS3R motherboard, which supports both DDR2 and DDR3 ram. On it, I have attempted to install 4GB DDR2 ram. It will not boot like this. A friend of mine searched the internet and discovered that OCZ (the manufacturer) ram needs 2.1 volts to handle 4GB, but it will run 2GB fine. But when I put the settings up to +0.7 volts (it does not tell me the current voltage), which is the highest possible, it still does not boot up. I have fiddled with other settings, but to no avail. > Does anyone know the required settings for this to work?
Hi, According to crucial:- http://crucial.com/uk/store/listparts.aspx?model=GA-P35C-DS3R You need a matched pair of 2GB sticks. You don't say whether you are using a pair or a single 4GB stick. It claims the following sticks are compatible:- http://crucial.com/uk/store/mpartspecs.aspx?mtbpoid=392CD53EA5CA7304 Which say that they are 1.8V parts. Interestingly the 1GB parts are 2.2V http://crucial.com/uk/store/mpartspecs.aspx?mtbpoid=F6D0533FA5CA7304 If you can boot to Ubuntu using the 2GB parts you can use dmidecode to see what voltage they are currently running at. For example here's what my laptop says:- Handle 0x0007, DMI type 5, 20 bytes Memory Controller Information Error Detecting Method: None Error Correcting Capabilities: None Supported Interleave: One-way Interleave Current Interleave: One-way Interleave Maximum Memory Module Size: 4096 MB Maximum Total Memory Size: 8192 MB Supported Speeds: Other Supported Memory Types: DIMM SDRAM Memory Module Voltage: 2.9 V Associated Memory Slots: 2 0x0008 0x0009 Enabled Error Correcting Capabilities: Unknown This gives you an indicator whether the voltage needs to go up (or indeed down).
