Intel DX48BT2 and TW3X4G1600C9DHX timings


Recommended Posts

Please help me to configure correct timings in the DX48BT2 BIOS.

Vista 64 and 32 crashes with Blue Screen IRQL_NOT_LESS_OR_EQUAL .

I have increased the voltage to 1.82 but still system is not stable.

Now I use default settings of my BIOS

1066 7-7-7-20 with only increased voltage 1.82 (instead of 1.5 default)

Please Help me.

My PC SPECs are availabe in my profile.

my FSB is 1333 so I want to run my DIMMS in 1333 as well.


here is what I got from MB datasheet (my DIMMa are placed in Black slots now, with no success).


- If you are using DDR3 1600 MHz DIMMs, it is recommentded that you only

populate two of the four DIMM slots, specifically one slot in each channel. It is

recommended that you populate slot 1 of each channel (black connectors).

- The maximum system memory for DDR3 1600 is 2 GB using 1 Gbit technology

memory in a 1R x 8 configuration (single-sided modules).

Download Memtest86+ V2.01 from--->

Download CPU-z from

Insert these BIOS Values:


Host Clock Frequency Override = Manual
x Host Clock Frequency (Mhz) = 333

Memory Configuration = Non-ECC
Performance Memory Profiles = Manual - User Defined

Reference Frequency = 333
Memory Frequency = 1333

tCL 7
tRCD 7
tRP 7
tRASmin 20
tRFC 60
tRRD 4
tWR 8
tWTR 4
tRTP 4
Memory Voltage 1.82v
Command Rate 2T

Boot to the Memtest CD and allow for two full passes. Then, if stable, enter Windows and run CPU-z. Post screenshots of CPU-z's CPU, Memory and SPD tabs.

thanks for quick reply!


My BIOS POST was unsuccessfull with 1333 so I changed it to 1066, and now it works.

Is there any difference in DIMM slots blue or black? now my DIMMs are in Blue ones A0 and B0.


Here are the screenshots:

Mem Test is still running Test #8, but I attached screenshot with errors. Or should I use Memtest v2.1 instead of 3.4?

Please let me know what to do next.

Thanks in advance!
