ASUS P5Q3 Deluxe discussion

[Amurtigress]

Have you tried putting 4 sticks of hyperX kingston 14400/1800Mhz ram.
Can't even run at 1800Mhz even up to 9-9-9-30 settings and 2.2vdimm.
It can only do 1600Mhz at 9-9-9-25....no way it gonna past 1650Mhz at 2.2vdimm.
Show me your good skills I would like to see it
Don't just talk, talk is cheap. Everyone here facing the same issues, think !

Oh folks, please. It is not possible, repeat: NOT POSSIBLE to run two pairs of DDR3 modules at their nominal speed and latencies just as if they were two. Because they pose a higher capacitive load to the northbridge's line drivers. This would only work of the maker of the modules would RATE them for a certain speed at four modules. But whatever they do, the ratings they sell them for is only for ONE pair. Period. Game over, basta. Physical limitations always apply, it's simply a law of physics. They simply sell them for the higher possible rating, which is way better marketing. 1600 or even 2000 sounds a lot better than 1333, right?! That's why you BOUGHT them after all.

My 4x1 GB Corsair DDR3-1600 sticks work well, but only at 1380. Rough estimation: Two pairs of modules would only work right at the next lower clock level. Ex. 1600s at 1333 or a bit more, 1333s roughly at 1066...etc.

Please get some knowledge about electronics. Without it you will never know what you're doing....just as a general plea to overclockers!
