I posted earlier about trying to optimize my ram. It seemed to have worked for a bit, but now im experiencing some strange phenomenon I can't quite figure out. My maxxmem scores have just slumped. I used to post in +11gb bandwidth @ 2133 mhz, but now I keep hitting low 9-10. In fact I've been experiencing some stability issues, so I downclocked the ram to 1866 - 9-10-9-28 but it feels like there is barely any difference in benchmarks. In fact the only way I can get the previous results is if I have chrome launched. Why is that? Northbridge is at 2600 on auto offset @ 1.45. I'm OC @4.4 + 0.13825 offset. Cool n quiet c6 enabled.

Originally posted by incubated View PostI'm not entirely sure what it does. Some say it's a throttling feature, some say it has to do with lowering the multiplier. Then there is the article by Dell that it's for some sort of server protocol. Basically it stands for "high performance computing" so I enabled

I'm not sure if this is relevant, but one of the things that improved my ram performance was lowering the tRas timing to 33 from the factory set 31. I read in OC mode tRas should be the sum of the first three timings +/- 1. Since I am running the ram in OC mode, I adjusted that timing and the smoothness is definitely perceptible. Icons load smoother and Windows is snappier. The benchmarks are still weird. Sometimes they post the proper scores without chrome, but the overall bandwidth seems to have gone up by ~. 4gb. Latency is slightly higher, as expected

It will probably remain somewhat weird as amd don't even mention supporting memory that fast. I would say pick whatever setting is most stable for you and stick with it. Not sure about your board but the tweeking I've tried with my nephew's amd setup nearly drove me nuts, if it fails it doens't even boot loop, just does nothing and to clear cmos I have to remove his video card (battery under it). and .4 gb/sec isn't much of a difference and likely more due to whatever else was running in the background during the test. I'd just go with gut feeling on what seems more stable/quicker and be happy it managed those speeds.
