4GB A-DATA 2000X + DFI DK P55-T3EH9 CAS8 fun!
Finally my turn to play with DDR3 modules on P55 - can't let you guys have all the fun! I bought 5 sets of 4GB A-DATA 2000X a while back tested them first on Asus P6T6 WS Revolution http://i4memory.com/f83/12gb-data-20...testing-20350/ and all either did DDR3-2000Mhz 7-8-7-24 1T or 7-9-7-24 1T at various voltages in 2x2GB and 3x2GB and 6x2GB config, but seems they behave differently on DFI DK P55-T3EH9. That or I have yet to master P55 chipset tweaking :)

System:
- Intel i5 750 L925B626
- Corsair H50-1 s1156 H20 + stock 59cfm Corsair fan (pump on cpu fan header, fan on cpu_pwm fan header)
- DFI LP DK P55-T3EH9 12/08 beta bios
- 128MB Gainward FX5200 PCI video card to start with
- 2x2GB A-DATA 2000X dual channel kit #4 (modules 7+8)
- 640GB Samsung SATA
- Pioneer DVD-R
- 1KW PC&C Quad SLI psu
- Additional cooling: 120x25mm Spire 75cfm fan over cpu socket/pwm area and 60x25mm Sunon 23.5cfm fan over PCH chipset heatsink
4GB A-DATA 2000X Kit #4
CAS 8 Overclocking Tests - Round 1
For CAS8 clocks on kit #4 definitely better than kit #5. But still DDR3-2000Mhz 8-8-8-24 1T has minor errors on DFI DK P55-T3EH9 even though same kit #4 on Asus P6T6 WS Revolution did DDR3-2000Mhz 7-8-7-24 1T at 1.58v ??? Weird ? Could be board/bios related or just my i5 750 doesn't like 7-8-7-24 on these modules than much ?

Strangely for kit #4 finding 8-9-8-24 clocks a bit easier to clock than 9-9-9-24 ?

2x2GB A-DATA 2000X dual channel Kit #5 modules 9+10
- on Asus P6T6 WS Revolution did DDR3-2000Mhz 7-9-7-24 1T at 1.60v
- on DFI DK P55-T3EH9 does
  - DDR3-2000Mhz 8-9-8-24 1T at 1.264v CPU VTT at 1.66v (4x 32M) - loosen tRFC 110 and tFAW 37 and tRRD 5
  - DDR3-2168Mhz 8-9-8-24 1T at 1.342v CPU VTT at 1.78v (single 32M) - loosen tRFC 110 and tFAW 37 and tRRD 5
2x2GB A-DATA 2000X dual channel Kit #4 modules 7+8
- on Asus P6T6 WS Revolution did DDR3-2000Mhz 7-8-7-24 1T at 1.58v
- on DFI DK P55-T3EH9 kit #4 scales with just CPU VTT more than Kit #5
  - DDR3-2008Mhz 8-9-8-24 1T at 1.264v CPU VTT at 1.58v (4x 32M) - tRFC 74 and tFAW 20
  - DDR3-2108Mhz 8-9-8-24 1T at 1.282v CPU VTT at 1.66v (4x 32M) - tRFC 74 and tFAW 20
  - DDR3-2194Mhz 8-9-8-24 1T at 1.282v CPU VTT at 1.70v (4x 32M) - tRFC 88 and tFAW 30

Nice findings about scaling kits with vtt :)

I am looking to future results. Personally I don't like P55 platform but I am going to test some soon.

Very nice results, thanks for sharing! Looks like 4GB modules clock nearly as well as 2GB ones! :up:

Thanks guys.. will do cas7 and cas6 tests then move onto gskill and corsair 2x2GB kits - so much ddr3 fun :D

I'd suggest for you to get your hands on i7 860/870 to be able to utilize 2:12 divider
It'd help you out with higher mem clocks ;)

thanks... should have better results as i figure out the p55 system voltages/settings :)

it's 2x2GB not 4GB modules ;)

yeah i5 750 stuck with 10x mem multi but i'm confident I can squeeze out more on this i5 750 as soon as I'm more familiar with the settings :)

first wall broken :D

DDR3-2274Mhz 8-9-8-27 1T at 1.72v
Loosened timings alot more, pushed voltages a bit more and dropped QPI frequency from 4.8GT/s (18x multi) to 4.27GT/s (16x multi) to achieve my highest frequency so far for bclk 227bclk as well as for memory frequency @DDR3-2274Mhz 8-9-8-27 1T at 1.72v validation and @DDR3-2247Mhz 8-9-8-27 1T at 1.72v for Super Pi 1M.

4GB A-DATA 2000X Kit #4
CAS 7 Overclocking Tests - Round 1
Now to CAS7 timings for 2nd kit #4. The same trend continues, kit #4 has better CAS7 overclocking headroom than kit #5. Goes to show not all memory are created equal :)

Kit #4 managed DDR3-1948Mhz 7-8-7-24 1T at same settings and same 1.70v vdimm which is much higher than Kit #5's max DDR3-1834Mhz 7-8-7-24 1T at 1.70v. But kit #4 like kit #5 didn't scale any higher with loosened tRCD of 9 or 10 (7-9-7-24 or 7-10-7-24).

Hi Eva ;)

My result from A-Data 2 x 2GB 2000 CL9 with 1.66v I'm not push too mouch vdimm for this kit, because my first kit go away with smth like 1.72v. Some 3D, and 32M :

For 32M only single core, because this cpu is realy crap :(
