12GB A-DATA 2000X Tri-Chanel @DDR3-2044Mhz 7-8-7-25

[eva2000]

Lots of fun these days playing with 12GB tri-channel configs!

Did some individual 2GB modules testing before hand and suspect these modules to be Elpida BBSE due to stable timings for DDR3-2000Mhz and higher for 2 of the 6 modules being 7-9-7-x and 8-9-8-x but 4 of the modules can do DDR3-2000Mhz 7-8-7-x.

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)
​

Stable for Super Pi 32M at least.

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:

• 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

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:

Do you do scientific simulations and/or multi million polygon renders?

 

[eva2000]

Nope, more DSLR/RAW, video encoding guy - plan to build new rig with virtualisation too so 12GB comes in handy

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!

Very nice, looks like those compete pretty close to the g.skill trident.

 

[eva2000]

Yup i think both A-Data 2000X and Gskill Trident 2000 have Elpida BBSE ics

here in Australia

6GB Gskill Trident 2000 = AUD$210-220
12GB A-Data 2000X = AUD$396-415

Very nice, I really like my g.skill. Seems like everyone buys the dominator when its slower out of the box by a good bit.
