Help Needed, Dfi Nf4 Ultra D - 3 Diagnostics Led On

[yunta]

Yes hardnrg, this is correct , it's a long beep, then a pause, then a long beep, pause.

I've got an Geil GL1GB3200DC (512mb) and a Supertalent D32PB12C (512mb) sticks in my hand.

I will try this.

One question, if i want to borrow one stick of my rig's son, i should to unplugg the psu power first ? i read this in another post about to disconnect any hardware of a DFI's mobo , is it ok ?

[yunta]

YES !!!! GOD is here !!!!

I put one stick of Corsair VS512MB400 on the first yellow slot (DIMM1) and my rig is in the Setup now !!!

I will set the Ram's parameters and try to boot normally.

Is needed to set another parameter before save the setup and restart ?

 

Post the results later ....

if you set the RAM voltage to 2.7, 2.75, or 2.8 and the following major timings:

 

tCL=3

tRCD=4

tRP=4

tRAS=8

CR=2T

 

then even the lowest performance DDR400 RAM will work...

 

if it doesn't post with two orange, try two yellow

[yunta]

What is CR=2T ?

 

First ok boot / new set

 

FSB bus freq = 200

LDT/FSB = Auto

LDT bus Transfer width = 16 16

CPU/FSB freq ratio = Auto

PCI express freq = 100mhz

K8 Cool 'n' quiet support = Disable

CPU vid stratup vlot control = startup

CPU vid control = auto

CPU vid special control = auto

LDT Voltage control = 1.20

Chipset voltage control = 1.50

Dram voltage control = 2.60 / 2.7

Dram +.03 voltage control = Disable

 

Dram freq set = 200

Command per clock (CPC) = disable

CAS latency control (tCL = 2.5 / 3

RAS # to CAS# delay (tRCD) = 3 / 4

Min RAS active timing (tRAS) = 8 / 8

Row percharge timing(tRP) = 3 / 4

Row Cycle Time (tRC) = 7

Row refresh cycle time (tRFC) = auto

Row to row delay (tRRD) = 02

Write recovery time (tWR) = 02

Write to read delay (tWTR) = 02

Read to Write delay (tRTW) = 03

Refresh period (tREF) = 3120

Write CAS# latency (tWCL) = auto

DRAM bank interleave = enabled

DQS skew control = auto

DQS skew value = 0

DRAM drive Strength = auto

DRAM data drive strength = auto

Max async latency = auto

**DRAM response time = normal

Read preamble time = auto

Idle cycle limit = 256

Dynamic counter = disable

R/W queue bypass = 16x

Bypass max = 07x

32 byte granulation = Diable (4)

in the DFI NF4 BIOS, it is CPC... command per clock is sometimes called command rate, the options are 1T or 2T... disabled will effectively mean 1T or 2T, I can't remember, but if you look at the options it's pretty obvious which value to choose

 

otherwise, the settings look fine for running stock speeds, although I'd go ahead and set the CPU VID / CPU VID Startup to 1.35 or 1.4v

[yunta]

In my setup CPC option are : Disabled - enabled - Auto, i'll enter Disabled and i'll change the values for CPU VID / CPU VID Startup to 1.35.

 

The new settings :

 

First ok boot / new set

 

FSB bus freq = 200

LDT/FSB = Auto

LDT bus Transfer width = 16 16

CPU/FSB freq ratio = Auto

PCI express freq = 100mhz

CPU vid control = auto / 1.35

[hardnrg]

cool... after thinking about it, command per clock would imply 1T, so enabled = 1T, disabled =2T...

 

it's probably not really critical, but I thought I'd mention it for running value RAM

[yunta]

Well, don't work with new settings.

With the stick in the DIMM1 (orange) = 3 diag leds ON and beep intermitent

With the stick in the DIMM4 (yellow) begin 4 leds on, 4th led blink twice and then off, 2 seconds after, 3rd led is off, after 2 seconds, 3rd led ON and 4th led blink twice, and repeating ...

 

 

PS: in the corsair value select especifications figure : 2.5 - 3 - 3 - 8 ,

i need to clear cmos for 15 min ok ?

[hardnrg]

well... for the settings that you call "first ok boot"... does it POST and then continue to load Windows (or other OS)?

 

try manually setting 2.5-3-3-8?

[yunta]

Yes, my rig is running again !!!

I've got XP installed.

Now, the second step .... OC

I go to read some OC guide, i suppose that there goods here !!!

 

Thanx Nate, hardnrg for your time and your help !!!! Thx overclockersclub forum too.

[hardnrg]

just in case someone has the same issue in the future, what was the solution?

 

the guides here from DFI-Street ARE the best

[yunta]

In this case, the problem was my memories incompatibility and that i'm a newbie in OC

the solution was :

-Extract all the unnecesary hardware

-Properly 15 minutes clear cmos.

-extract all the memory sticks.

-put only one stick in the yellow slot (near the mobo's edge) , try in the others sticks first, beginning in the orange stick near the cpu.

-when the rig POST, set the memories values for your memory and reboot, if post again, reinstall one at time , all your components , don't forget power off the PSU and/or disconnect the power connector.

 

PS: if you have a good links about OC here, this will be appreciatted a lot
