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

[eva2000]

More 6x2GB = 12GB fun

System:

• Intel Core i7 920 3845B260
• EK Supreme LT 1366 / FESER 480 / MCP655
• Asus P6T6 WS Revolution
• A-Data Xtreme Series 2000X 9-9-9-24 1.6-1.8 rated memory
• 512MB Inno3D 8800GT OC Edition 190.62WHQL
• 750GB Samsung SATA
• Pioneer DVR-217 DVD-RW
• Corsair HX1000 PSU
• Dual Boot - WinXP Pro SP3 (nLite fully updated) with Vista Theme & Win7 Ultimate 64bit RTM

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

Nice eva, I know you're in aus, but do you know if anyone offers these in the states?

 

[LittleLizard]

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

 

[Bo$$]

they are safe til 1.8V....

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.

they are safe til 1.8V....

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

that explains it, might say more specifically on the website or in the manual

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

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!

WOW do you play any games at those RAM speeds your load times must not even exist lol!
