12GB A-DATA 2000X Tri-Chanel @DDR3-2044-2112Mhz

[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

very strong results with 12GB. So 7-8-7-25-2T is 24/7 stable @ 2000mhz?? Thats a really nice OC on 12GB kit

[over@locker886]

Really nice tri-channel kit!

How perform in 32M, 12GB vs 6GB?

[WaterFlex]

well done, EVA! Nice kit also

[zalbard]

Stunning RAM! Nice job!

[aslanwas]

Nice testing and impressive results with 12gb

that's 3x 4GB dual channel kits but only benchable for 12GB as 2 of 6 modules don't like 7-8-7-x 2000mhz for stability but prefer 7-9-7-x

Really nice tri-channel kit!

haven't done any direct comparisons of 6gb vs 32m yet heh

well done, EVA! Nice kit also

thanks

Stunning RAM! Nice job!

Nice testing and impressive results with 12gb

thanks, shame 2 of the modules hold the other 4 back in terms of liking lower vdimm <1.64v than the other 4 heh.

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!

Great pushing george ! man you can really squeeze ram lol
2112 one of my fav numbers

[cloud369]

Nice test

[mike.shine]

Very informative and impressive test...

thanks ... alot of fun playing with 6x2GB... wishes for 6x4GB playtime

Nice test

thanks

Very informative and impressive test...

thanks.

FYI, I bought another 2 sets of these as they're the cheapest per GB performance memory available in Australia right now just under 6GB Gskill Trident 2000C9 in terms of per GB costs - AUD$35.5/GB vs AUD$36.50.

Two more sets of 4GB A-DATA 2000X dual channel (yes 20GB A-Data 2000X!) hoping to get some that like higher vdimm but got the opposite, one set DDR3-2000Mhz 7-8-7-24 1T at 1.58v and DDR3-2046Mhz 8-9-8-24 1T at 1.58v for memtest86+ v4.0 looping and other DDR3-2000Mhz 7-9-7-24 1T at 1.60v. Optimal vdimm getting lower and lower LOL.

Unfortunately, DDR3 prices seem to be skyrocketing lately, so will be hard to get hold of other memory for my x58/p55 memory kit comparison reviews I have planned.
