Q2X4096-85C5DF on a Gigabyte GA-X48-DQ6

Hi Ram Guy,

 

I'm currently building a PC with Q2X4096-85C5DF on a Gigabyte GA-X48-DQ6 with all 4 DIMM's populated It gets stuck in a BIOS recovery loop.

When I remove the 4th module the board posts and memtest runs 100% without fail.

Is this the same issue with the memory controller as i have read in other posts?

I have run memtest on each individual module and have passed infinate loops without any address errors.

I have also tried dropping the Dram back to 800Mhz and it still gets stuck in the BIOS recovery loop.

I have also tried 2 of the Gigabyte GA-X48-DQ6 incase it was a faulty motherboard.

 

If you could please let me know where I'm going wrong it would be muchly be appreciated.

Yes, this is the issue.

Download memtest from--->
and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Enter your BIOS. On the main BIOS screen press Ctrl + F1. You will see the screen flicker. Next select the MB Intelligent Tweaker option. On that screen you will see many additional settings that were not there before.

 

MIB Intelligent Tweaker (M.I.T.)

CPU Clock Ratio = 9.5

CPU Host Clock Control = 333Mhz

PCI Express Frequency = 100Mhz

C.I.A.2 = Disabled

System Memory Multiplier = 2.4

DRAM Timing Selectable = Manual

CAS Latency Time = 5

DRAM RAS# to CAS# Delay = 5

RAS# Precharge = 5

Precharge Delay (tRAS) = 12

ACT to ACT delay = Auto

Bank Write To READ Delay = Auto

Refresh to ACT Delay = 0

Read to Precharge Delay = Auto

Memory Performance Enhance = Normal

Dimm OverVoltage Control = +.4V (for Version 1.xx) +.3V (for Version 2.xx+) Look at your DRAM module for the proper voltage setting.

PCI-e OverVoltage Control = Normal

(G)MCH OverVoltage Control = +.35V

CPU Voltage Control = Auto

Robust Graphics Booster = Auto

 

Boot to the Memtest CD allowing for two full passes.

 

Results?

Derek,

 

I'm having problem of endless restart loop and random restart as well.

 

here's my thread

http://www.asktheramguy.com/v3/showthread.php?t=72228

 

what's the BIOS setting for my motherboard as i have two of 2x Corsair TWIN2X2048-8500C5D 2GB (2x XMS2 1GB) PC-8500 (1066MHz) DDR2 RAM which in total 4 GB of 4 memory slots.

 

thanks.

OK,

 

now i get it, so by default all Motherboard uses 1.8 v

while new hi spec. RAM as of mine should be using 2.1 V as minimum.

 

I'll run these setting below:

------------------------------------------------------------------------

1. enter the bios, (press delete key as it is booting)

When the bios comes up the first thing to do is press ctrl+f1.

That will enable advanced bios features for Gigabyte Board.

for Gigabyte X48 (from memory) there should be "DDR2 Overvoltage control" setting .

 

change to +.3 v because 1.8V is standard so i shall add .3 to make it 2.1V

 

Also on the same page change "memory timings" (or similar) so I can see: (Set memory manually)

 

5

5

 

5

15

etc

etc

etc

 

Change to first 4 to 5-5-5-15 (it will maybe be on 5-7-7-21 by default)

Change row refresh to 56

Make sure static tread is no less than 7

 

save and exit.

"MCH overvoltage Control" +.25

------------------------------------------------------------------------

 

would that be OK to the PC component ?

I'm afraid of broke down the memory or any other component.

I would try setting the memory frequency at DDR800 first then DDR667 if its not stable then the timings would be Cas 5, TRCD 5, TRP 5. TRAS 15 and command Rate to 2T or 2N and the memory Voltage to +.03 Volts and MCH overvoltage Control" +.25 and all other settings left at AUTO or BIOS default

Yes, i did that already on my GA X48-DQ6 but still today, it failed to POST properly and sometimes it also hangs after in the Windows,

 

then i ran memtest 3.4a

 

and here's the result:

 

as per attachment.

 

it errors in millions in bank 0

 

any idea please ?

how to down grade the RAM speed in Gigabyte X48-DQ6 ?

is there any option to do that ?

 

thanks.
