Hello ladies and gentleman,as the star of our show we will introduce micron's latest addition to the D9-DDR3 flock,D9PSG&D9PSH.Why are they together?Because there are mixed chips on a lot of ballistix line.Same modules use D9QMT and are in the same park,so basically u can't be certain of what you get only by removing heatspreader ...
Well here is the guilty product:
http://www.crucial.com/store/partspe...4G3D1608ET3LX0
General characteristics:
-they react to cold,20 to 0 degrees yielded about 100 mhz more at same latency
-they run very tight secondary and tertiary,basically as tight as your imc can handle,only exception is trfc which has to be in the 120-140 range for high frequency
-they react to voltage.Now comes the tricky part,as they don't react in a linear way.Basically 2400 C9 is stable for memtest with 1.64,but over 1.70 NO POST.2400 C8 will post and be stable at 1.77V.2400 C7 will post and somewhat stable for spi at 1.89
-they will not run any twcl lower than 7,but they don't have that twcl 8 bug,so twcl8 is lightly slower than twcl7
-they will run 32M about the same they can post,for example 2800C9 was 32M stable but 2860 did not post no matter what
-they are not binned,basically looks like crucial just threw random chips with no binning,one module did not boot over 2000 no matter what,other 3 did that but only 2 can run 2800 stable
-they do not have any trcd wall like good ole PSC or BBSE,2000 7-7-7,2200 8-8-8,2400 9-9-10,2600 8-9-11,2700 9-10-12,2800 9-10-13 are achievable for 32M
Results:
2800 9-9-12 S-pi 1M:
2800 9-10-12 S-pi 4M:
2800 9-10-13 S-pi 32M
Testing was done using a 3570K with a powerfull imc(3160+ valid on air),Asus Maximus V gene and 0-1 degrees celsius ambient.However the bad fact is they are somewhat slower at 32M that comparative samsung 2800 9-12-12 eventhough they blow them out of the water at AIDA tests,i suspect it's either likely mobo is not tuned specially for this kind of IC's.
Will post some more results at lower frequency coupled with some memtesting for daily users later.
So,what are you waiting for?Start binning and pour some ln2 on them
