Subtimings: Why You Should Adjust Them


Zertz

Recommended Posts

Ran a few tests on my new Mushkin RAM and felt like benching those sticks

 

1120MHz is about the max frequency they would boot at 2.1V so all my tests are done at that speed and main timings are set to 5-5-4-14

 

After a few restart and minor tweaking I came up with that... Not too bad, but far from being great

So I fired up memset and simply changed Performance Level from 9 to 6 (any lower resulted in a system lockup):

Of course I had to shoot for more, so I tweaked it a bit more:

So I gained about 400MB/s just by tweaking subtimings a bit, that's pretty good IMO :)

 

I'll update this when I get the CPU clock up B:)

Yeah, the system will lock/restart sometimes :P

 

Just don't use the save feature if you're not sure whether it'll work or not.

If you can get the Performance Level any lower that helps alot, if not, just try slowly lowering them one by one ;)

Did that, but that's as much as I can do. <_< If I try and lower anything anymore I get lockup/restart. So is this as far as I can go? Sandra says its only 54.5% efficiency and I'd like to get it up to 75%, but then again 9GB/s isn't that bad...
