Motherboard RAM overclocking? :/

Specs: Windows 7, Intel® Core™2 Duo Processor E6750/2GB RAM
Heeey guys. I did ask this question about a week ago but i didn't really get my answer.

So i just got this old mobo (Asus P5G41T-M LX) and in the specs it says it supports 1333 memory but in brackets it says (O.C). So what does that mean? I know OC means overclock, but i'm building a new system and planning on getting 4GB of 1333 RAM. Will my system post?

I just don't understand why it's got (O.C) in brackets, does that mean i'd have to change a setting in the BIOS or something to get it to post or something?

Thanks guys :)

Also, i don't think that last bit makes sense. But you know what i mean ;)

Apparently & for whatever reason, your board won't autodetect DDR3-1333 as DDR3-1333, so to get to run it at that speed, you will have to manually configure the RAM speed in the BIOS. I doubt it will prevent the system from booting - the RAM will simply run as DDR3-1066 until you change the setting. If you're concerned about buying compatible RAM, stick to what's listed in the QVL at the ASUS website.

Thanks for the reply. Cleared things up a lot.

I checked the QVL and it does support the DDR3-1333 4GB that i was hoping to get so i guess i'll just be changing the speed to 1333 when it's all up and running.

Will it be difficult changing the speed in the BIOS or will it just be a simple option to change from 1066 to 1333?

Some RAM will not run at the listed specs even when forced. I have found that RAM that uses higher voltage settings is more prone to this occurrence. I suggest you buy RAM that is rated to run at JEDEC voltage settings. If you want to overclock the RAM you can always juice it yourself. Don't pay extra for RAM that is already juiced.

See the link below for an explanation on JEDEC.

If your board supports DDR3 1333, then buy that. Like Mickliq said, you would have to overclock it if it wasn't supported, but you say it is. Look at OtheHill's post also.

If u exceed 1.65v u will fry the motherboard, if u get errors reduce to 1.6v(when u increase memory voltage make sure to reduce memory timings)

If i remember correct ddr3 can go down to 667mhz.
