Mobo Limit?

[Fog]

Hey guys, I have an ASUSTeK Computer INC. P5G41T-M LX (LGA775) motherboard and my dad said he cant buy me a ram at 1333mhz cause my ram currently 8.00 GB Dual-Channel DDR3 @ 400MHz (6-6-6-15) is the limit for my mobo ( it cannot run more than 400 mhz)

I think its not like that but I don't want to waste money, so can someone answer my question?

Thanks!

DDR3 running at 400Mhz ? Something is wrong here.

It's running at 800 Mhz.

Software like CPU-Z show 400 Mhz (half). DDR = Double Data Rate.

I'm using speccy are u sure it halves it?

It must be 800 Mhz(never seen a 400 mhz ddr3 module). If your mobo supports upto 800 mhz only, then even if you buy a 1333 mhz module, it will automatically underclock to 800 mhz when used on your mobo.

200% sure.

dude my mobo is also the same and u can run at 1333Mhz only if u 'overclock' it on that mobo otherwise it'll stay in at 800mhz only, not 400mhz .and mobo is limited to 8gb only

Yes, DDR values show half the speed because the technology has two operations per second*. Effectively this means double the speed at the same frequency, an "effective 800MHz".

* = oversimplification, but I guess its enough
