Hades25 Posted October 9, 2003 Posted October 9, 2003 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 .....

AYoKoNA Posted October 9, 2003 Posted October 9, 2003 (edited) what slots do you have the ram in?? U have 3 slots on your board correct? According to your manual you should place the ram in order farthest away from the processor. http://www.fic.com.tw/support/motherboard/...px?model_id=118 Edited October 9, 2003 by AYoKoNA Quote Share this post Link to post Share on other sites More sharing options...

exeter_acres Posted October 9, 2003 Posted October 9, 2003 What are you using to test bandwidth?? Quote Share this post Link to post Share on other sites More sharing options...
Hades25 Posted October 9, 2003 Posted October 9, 2003 using sandra.....im at work know so i cant do a scrnshot....should i try another program? Quote Share this post Link to post Share on other sites More sharing options...
exeter_acres Posted October 9, 2003 Posted October 9, 2003 No Sandra is just fine, just wanted to run it on mine to get an idea for comparison.. Â Â I get about the same bandwith speed as you.. A7N8X deluxe that I know is running in dual channel mode.. Â Â Hmm? Quote Share this post Link to post Share on other sites More sharing options...
Hades25 Posted October 9, 2003 Posted October 9, 2003 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 Quote Share this post Link to post Share on other sites More sharing options...
AYoKoNA Posted October 9, 2003 Posted October 9, 2003 (edited) 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!!

Hades25 Posted October 9, 2003 Posted October 9, 2003 even though your at 74% you still have higher bandwidth..... why cant exeter_acres and I get that bandwidth.....???? Â hey why you at 3.0 latency? i figured your ram should handle 2 Quote Share this post Link to post Share on other sites More sharing options...
AYoKoNA Posted October 9, 2003 Posted October 9, 2003 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 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. Quote Share this post Link to post Share on other sites More sharing options...

Guest FxXP Posted October 9, 2003 Posted October 9, 2003 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.
