Overclocking FSB and MEM correctly, etc


XMSUser

Recommended Posts

Hi,

 

I recently bought CMX4GX3M2A1600C7 and would like to know what settings I need to set. This includes FSB freq', MEM freq', memory timings and voltages.

Although the main memory settings and the voltage are noted on the stick itself, I still want to know what I need to set in the other ones.

Note that on the stick it says 1.65v and my motherboard can only set even numbers. Do I need to set 1.66v? 1.64v? something else?

 

Thanks to anyone who can help! :)

Every set of hardware is different. What works for one person's mobo/system will not necessarily work on your's even if their PC has the same exact components. That is the reason why learning the ins and outs of BIOS settings will help you understand the challenges and obtain the most from your PC.

 

The timings and voltages listed above are where you should start. It does not matter if you set your RAM voltage to 1.64V or 1.66V as the RAM is not that sensitive. It's typically tested at 1.6V and 1.65V is specified as the "nominal voltage" to allow for line sag and system voltage variations.

You can use CPU-Z to look at the SPD timings table. You might find a few different combinations that you can use in there and it will give you a good idea. In the BIOS if you simply select "use SPD" it will only use the default SPD column when in reality sometimes a module has multiple configurations, especially with different voltages and speeds.

 

So like I said, you're best to go into CPU-Z and see what's in the table, then force the fastest config manually and see if that's stable for you.
