DFI and TwinX 3200LL V1.2


Recommended Posts

Hello Guys,


I need your point of view on this... Could you help me to set up correctly my TwinX 2X512 PC3200LL V1.2 with my DFI NF4 Ultra D.


Here is my Spec :


DFI LanParty UT nF4 Ultra-D Bios 3.10

Corsair TwinX XMS DDR 2x512 Mo PC3200 Low Latency

AMD Athlon 64 3000+ Socket 939

Thermalright XP-90C

Fortron FSP500-60THN Blue Storm

Asus Extreme AX300/TD

Cooler Master Wave Master TAC-T01-EK

LG GSA-4163B


Here is my bios settings :



a1. LTD/FSB = X4.0

a2. CPU/FSB Frequency Ratio in Auto

a3. PCI EX Frequency = 105 ATI video cards.

a4. Cpu Startup VID = 1.425 Volts.

a5. CPU VID 1.425 Volts.

a6. CPU VID Special Control = 110%

a7. LTD voltage = 1.4 Volts.

a8. Chipset Voltage = 1.8 Volts.

a9. Dram Voltage = 2.9 Volts.


5. Genie Bios first entry at top> DRAM CONFIGURATION

a1. 200 Dram Frequency 1:1

a2. Enable CPC

a3. 2.5

a4. 04

a5. 07

a6. 04

a7. 07

a8. 14

a9. 05

a10. 03

a11. 02


a12. 05

a13. 3120

a14. 05

a15. Bank Interleave= DISABLED


a16. DQS Skew Control = INCREASE

a17. DQS Skew Value = 0 (zero)

a18. Dram Drive Strength= Level 6

a19. Dram Data Drive Strength= Level 4



a22. IDLE CYLCE= 256 cycles

a23. DYNAMIC Counter= Disabled

a24. R/W Que Bypass = 16x

a25. ByPass Max 7X

a26. 32 Byte Granularity = Disable 8 Bursts.


So far now everything's fine and after 2 hours I never had any error on memtest and other bench as 3Dmark and so on.


Dear RAM Guy, I know that my memory TWINX1024-3200LL Type : DDR-400 (PC-3200) (2 x 512MB) seems to work by default on Latency : 2-3-2-6 but I had to changes the bios settings to be able to install my Windows XP, as I was only getting error at this stage and I am also not sure if the board was getting the latency correctly from the memory, so I am not sure if this actual settings is a great thing for my 2 sticks. What do you think about the bios settings, the memory timming and what is your point of view on it ?


I need your knowledge my master :bigeyes:

Dim Voltage to +.2/2.8 Volts:

CAS Latency CL=2.0

Row Cycle Time tRC Bios Default

Row Refresh Cyc Time tRFC Bios Default

Ras# to CAS# delay tRCD 3

Row to Row delay Bios Default

Min Ras# Active Time tRAS 11

Row Precharge Time tRP 2

Write Recovery Time Bios Default

Write to Read delay Bios Default

Read to Write Delay Bios Default

Refresh Period tREF Bios Default


Then test the system with http://www.memtest.org and make sure it's stable! If you have problems, I would set Enable 2T Timings or CPC to 2T or to AUTO and test it again!

You better update the bios to 510-3


Try these:


HTT = 5X





Trc=8 (Trc = Trp + Tras)

Trfc=11 (Trfc = Trc + 3)




DQS Skew Control = Auto

DQS Skew Value = 0 (zero)

Dram Drive Strength= Auto

Dram Data Drive Strength= Auto



IDLE CYLCE= 256 cycles

DYNAMIC Counter= Disabled

R/W Que Bypass = 16x

ByPass Max 7X

32 Byte Granularity = Disable 8 Bursts.

Hello Guys,


Dear Ram Guy, I have modified my settings as you told me. Memtest was working fine without any error for 4 Hours. So far everything’s fine. Please can you tell me what is the real difference between my old settings and yours?


Dear Ferry_G, thanks for your support. My board is a DFI NF4 Ultra D and I am using the last bios given by DFI 3.10. I supposed we do not have the same board as you mentioned a 510-3 bios version, but I may be wrong ;)

Anyway after so many attempts I have what I was looking for, a stable system, as in other hand I am for now limited by the tiny graphic (ATI X300) card but I may try your Ram settings later on.

I also wanted to tell you that I did not install the NF4 firewall and SW Drivers as I had few issues with.


Thanks again for your support and comments.


Corsair always the best for me 

The latest bios for your board is 618-3. Your mb have same bios as mine.


If you didn't install nV SW IDE driver, your computer will gain bottleneck on IDE access.


Can you install the nVidia unified driver v6.53 1 by 1, and then the ATI driver so you'll know exactly which devices cause the problem.


Glad to hear that your system already stable. :):

Hi Ferry_G,


thanks for your reply. I do not have any more problems for now and I hope for a long time ;).

I wasn't aware for that bios version. I did check on the DFI web site and I can't see where you found this 618-3 :cool:

Anyway thanks again, see you on DFI forum.


Thanks again for the Corsair forum that make my stuff working together.
