CORSAIR XMS3200C2PT Question

[JamesUK]

Hi, i have the below system (in my sig) and my memory settings had always been running at the default settings the bios sets of 8-3-3-3 2T

After reading a lot of articles on my board and this ram it appears that its supposed to run at about 6-2-2-2 2T and also says them figures on corsair's website.

So, my system is now running as these settings and although my system hasn't give me any error beeps and my system starts fine and programs dont appear to crach at all, i have noticed my programs appear to be running a lot slower. I have noticed with a lot of programs open that my system has been unresponsive for a bit and programs generaly taking a bit longer to load things.

Can anyone explin any reasons about this, i would have thought this would make my system respond better.

Also my system is not overclocked at all and all voltage settings are on auto.

Thank you inadvance.

It could be that something else is making your system slow. An easy way to test this would be to note which aps are slow for you and under which circumstances, then change the timings back to 3,3,3,8 and see if they are any faster

Personally I suggest some benchmarked to prove that performance is suffering.

You should see a performance increase from CAS3 to CAS2.

Also, download CPUZ and give us a screenshot of all the memory related settings and we'll see if anything is out of whack.

well i have just switched the ram voltage from auto to 2.75 and also changed from 2 t to 1 t and there is a pretty big change in numbers in sisoft sandra memory benchmarks.

i have done a benchmark between 8-3-3-3 2t and 6-3-3-2 2t and there was little difference in the numbers.

they turned out to be: (with voltage set to auto)

memory bandwidth benchmark - 6-3-3-2

ram bandwidth int buff 4821
ram bandwidth float buff 4845

memory & cache benchmark - 6-3-3-2

combined index 6924 mb/s
speed factor 9.3

-------------------------------------------

memory bandwidth benchmark - 8-3-3-3

ram bandwidth int buff 4822
ram bandwidth float buff 4822

memory & cache benchmark - 8-3-3-3

combined index 6902
speed factor 9.3

After changing the voltage to 2.75 and also to 1T at 6-3-3-2

all numbers went up by nearly 1000 points apart from the speed factor number on memory and cache benchmark which seemed to actualy go down to exactly 8.0

but the other increases do seem like the 1T option gives quiet a speed increase.

[Pitch]

Yes, 1T does give a large performance boost over 2T.
