Hi, I dont know much about ram and have a few questions
i currently have
s478 3.4E HT 800fsb
gigabyte ga-8ig1000pro-g
x800xt
2 x 512mb ddr400 in dual channel (value/generic ram?)
firstly what is a good app to benchmark ram??
secondly i have noticed that when i lower my latencies from 3-3-3-8 to 2.5-3-3-7 that my bandwidth gets slightly lower according to RMMA (Right mark memory analysis) does that sound right?
what are the benefits of lower latencies?? and would the benefit of lower latencies outweigh the slight loss of bandwidth?
and then in the gigabyte BIOS in the hidden options it has a few tweaks for ram again, particularly being MIB(memory intelligence booster) psb parking, fast chip select and another option i cant remember without rebooting and having a look
anyway i enabled these tweaks and the ram timings are the same but the Read latency in RMMA has dropped quit a bit, and bandwidth has dropped again with the exception of READ bandwidth which actually got a fair boost
here are my results from RMMA with ram at 3-3-3-8 and all the gigabyte mobo memory enhancments turned on, i have no idea if this good, bad or average....
Synthetic tests:
Real read bandwidth - Average 5249 - Maximum 6091 MB/s
Real write bandwidth- Average 1907 - Maximum 4248 MB/s
Read latency - Average 49 - Minimum 47 - Maximum 68 ns
Performance tests:
Real RAM bandwidth - Average 2635 - Maximum 2979 MB/s
so is that good or bad for ddr400 in dual channel??
should i try to lower the latencies more or should i try get more bandwidth?
cheers
