Talking 12GB A-Data 2000X Tri-Channel @6-7-6-24

More 6x2GB = 12GB fun

System:

12GB - 6x2GB A-Data 2000X
@DDR3-1702Mhz 6-7-6-24 2T at 1.62v
(Kit 1 + 2: module #1 + #5 + #4 + #3 + #2 + #6)

It paid off to individually test all 6x 2GB A-Data 2000X modules and sort out the problematic module #3 as now it's sorted out, clocking 12GB - 6x2GB config is so much easier, straight into 12GB A-Data 2000X @DDR3-1702Mhz 6-7-6-24 at 1.62v. Kept CMD Rate at auto for 2T just for starters.

Stable for Super Pi 32M at least. Need to work on HyperPi 8x32M tommorrow

get a bit risky. up the voltage to 1.7 and see what these can do

not sure don't see them on newegg which is where i usually compare prices with Australian prices. Probably might see them later on. I only know of memoryc.com which stocks theses and ships internationally.

2 of my 6 modules likes <1.64v vdimm better than high, so for 6x2GB might not be optimal for higher vdimm although the the 2 lower vdimm liking modules can still pull off in 3x2GB config this at 1.64v for 32M pi







haven't tried with 6x2GB yet other timings than 6-7-6-24 yet.

Yeah i think A-Data 1.8v rating is for non-p55/x58 boards i.e. x48/p45.

12GB - 6x2GB A-Data 2000X
@DDR3-1909Mhz 7-8-7-25 2T at 1.62v
(Kit 1 + 2: module #1 + #2 + #4 + #3 + #5 + #6)

Now to test higher memory frequency with 7-8-7-25 timings at 1.62v vdimm. 1T results in ~10% more memtest86+ v4.0 reported bandwidth than 2T, but 1T was only stable for Super Pi 1M and failed 32M. 2T was much easier to pass Super Pi 32M @DDR3-1909Mhz 7-8-7-24 2T with tRFC 110, tFAW 37 and B2B 4.

Swapped module #5 and #2 places so the 6x2GB A-Data 2000X config is as follows module
  • Dimm 1 = module #1
  • Dimm 2 = module #2
  • Dimm 3 = module #4
  • Dimm 4 = module #3
  • Dimm 5 = module #5
  • Dimm 6 = module #6

System:
1T RTL A/B/C = 58/60/62






2T RTL A/B/C = 58/60/61










6x2GB = 12GB A-Data 2000X Max Validation
@DDR3-2044Mhz 7-8-7-25 2T at 1.62v / 1.5v QPI/DRAM

Managed to push 6x2GB A-Data 2000X to DDR3-2044Mhz 7-8-7-25 2T validation with 1.5v QPI/DRAM and 1.62v :woot:

Now pushing 12GB A-Data 2000X to 8x32M Pi stable @DDR3-2000Mhz 8-9-8-25 2T at 1.62v vdimm with 1.50 QPI/DRAM uncore voltage with max validation at same voltages @DDR3-2112Mhz 8-9-8-25 2T!

System:
12GB - 6x2GB A-Data 2000X
@DDR3-2000Mhz 8-9-8-25 2T at 1.62v
(Kit 1 + 2: module #1 + #2 + #4 + #3 + #5 + #6)


tRFC = 110
tFAW = 38
B2B = 4

HyperPi v0.99b - 8x32M Pi



Single Super Pi 32M



Everest Bandwidth





12GB - 6x2GB A-Data 2000X
@DDR3-2112Mhz 8-9-8-25 2T at 1.62v
(Kit 1 + 2: module #1 + #2 + #4 + #3 + #5 + #6)
