Hi i just tested my ram and i dont know if i had good points...? i dont know anthink about memory timings and i ask you if i have ok memory timings?

you have two Modules yet your not running dual channel?? - why is that??

and 2T is holding your bandwidth back by around 1000 points.

09-01-05, 11:44 AM
how can i fix that? i thought i ran it on dual but anyway i dont know much memory systems. Can anywone help me there ?

09-01-05, 11:57 AM
what is 2T? how to fix it to run my memory normal?

09-01-05, 01:08 PM
I take it back - you are in dual channel mode - as it says: Width : 128-bit

however you still need to sort out the command rate - in your bios under DRAM timings you should select "manual" and then set the "command rate" to 1T rather than 2T.

i searched in my bios but didnt find dram timings... i will restart again and looked for this...

09-01-05, 02:05 PM
Be careful too. Only change Command Rate or whichever option lets you select between 1T or 2T, and make sure it's at 1T.

have you got idea how to find this in my bios...? phoenix-award bios cmos setup utilty?

im sure your MoBo manual would tell you were that setting is - have a read.

09-01-05, 03:25 PM
hmm I was wondering.. is it AMD only? because i dont have it..


09-01-05, 03:36 PM
no its both Intel and AMD - also in the above piccy you have Performance acceleration mode set to Auto - you want that set on ON for an Intel system dude.

perhaps you guys should update your Bios's - often that adds options that wer'nt in the original release..........

for ASUS boards if your not sure what your doing there is an app called "Live Update" available @ station-drivers amongst other places.

ok i done this. i did on 1T in bios. now i got Benchmark Results
RAM Bandwidth Int Buff'd iSSE2 : 5898 MB/s
RAM Bandwidth Float Buff'd iSSE2 : 5838 MB/s
Results Interpretation : Higher index values are better.

yep for 1000 pints is now better many thanks guys! in games is better too now...what do you think? thanks

Where can I get this memory tester??

09-02-05, 06:37 PM
its called sisoftware Sandra... google
