Memory Bandwidth

copsey · 16 Sep 2007 at 10:41

Guys
Yesterday I went through and finally tweaked all my memory timings and sorted out the overclock on my system. On the memory front, I've got tight timings and a 1:1 ratio sorted, and Sandra shows me with extremely low latency and the windows experience score for them is 5.9. However the memory bandwidth is very poor compared to the other reference systems.

Is there something I'm missing here?

TIA

i've got
read 5864
latency 63.5

others are not readable due to it being a trial version (on a domain) but i can see
write < 6279
copy < 5117

I'm not sure how to find that out - please have a look...!

thanks!

oh - see where it says "Channels #" and that says Single. Should that be double?

that will be it - i'll swap them tonight and come back!

i will have a go but i'll need to take all the voltages into the red. Its reported as 1:1 in cpuz at the moment, does it lie?

ah this has done the trick! Talk about schoolboy error!

Everest:
Read: 7836
Write > 6279
Copy > 5568 (significantly so)
latency 58.4

God that is a MASSIVE difference.

Wicked thanks all!

Sticklyman, my CPU is overclocked running at 3.42GHz. I tried nudging it further but no go...

I went to 3.15 on stock voltages also.

3.4 is a pretty good step up from 2.4 though!
