Can't Run Dual Channel Ddr


Recommended Posts

My mobo (FIC AU13) supports dual channel ram but when I run a mem benchmark it gives me 3.0gb bandwidth.....that is when i have tried every slot combo.....and of course its the same brand and type mem 2 512 chips is what ive been trying to do it with.........no matter what i do it wont give me 6.4 gb .....

ahh...see we're both in the same boat......i though i saw someone post something about dual channel and saying they were hitting 6.4gb

 

so maybe the normal bandwidth is about 1.6gb and we have dual channel running? and that means i have no idea what im talking about then

These are my results on Sandra. Dual Channel DDR400 Crucial (P.O.S. Mem Timings that crash when i try to lower them :( )

The maximum bandwith is 6656, But if you look at BANDWITH EFFICIENCY, its at 74%, which gives me my 4900mb/s mark (74% of 6656 is 4900)

So take a look at both those numbers MAXIMUM BANDWITH, and BANDWITH EFFICIENCY!!

even though your at 74% you still have higher bandwidth..... why cant exeter_acres and I get that bandwidth.....????

 

hey why you at 3.0 latency? i figured your ram should handle 2

Cause i got an Intel :P J/K hmmm.... I don't know why your systems are getting such low marks on Sandra.

Also I tried going to 2 latency and system crashes. Have to take the cmos battery out to reset everytime. When pc3200 Mushkin Level II goes down in price i will get that probably belt out between 5200 to 5400 on Sandra.

If you can't dual channel, here is your reason: You are running 128 bit DDR.

You can't run 128 bit sticks in dual channel as that is what dual channel is designed to do, run 2 x 64 bit DDR sticks in 128 bit mode.
