How
we test and built DDR 466 Module! |
| |
 |
Well-tested
DDR466 Memory devices compose TwinMOS
DDR466 MHz (PC3700) DIMMs.
These
DDR466 Memory devices can correctly
run Double data Rate at 466MHz, and
are tested by Advantest T5585
test machine. This Advantest
T5585 test machine is the most
superior testing machine for DDR memory
devices testing, and can reach to 250Mhz
clock rate (500Mhz Double data Rate).
From the top marking of these devices,
TwinMOS has shown the device operation
speed.
43B or 43D: (difference
by 0.15u or 0.13u chip process)
4.3ns (233Mhz) clock rate, and means
466Mhz Double Data Rate. CL=2.5
At TwinMOS’s production line and before
shipping to customer, all these PC3700
DIMMs are
100% tested by GA-8SQ800Ultra
(GIGAbyte Motherboard) with Intel P4
2.53G (FSB533) to prove them to be real
PC3700 DIMMs.

Basic
Knowledge of Motherboard |
| |
|
| (1) |
Not
every DDR 400 M/B supports DDR466,
some M/Bs can’t recognize DDR466
memory, many problems happened.
|
| (2) |
How
to check if M/B can support DDR466?
1. It can do memory clock settings
to DDR 466 (233 MHz) in BIOS setup
menu.
2. Memory frequency can be shown
when startup. ( DDR 333,DDR400
or DDR466,etc….) |
| (3) |
Higher
FSB needed. (the FSB of AMD CPU
is 333MHz, Intel CPU can support
800 MHz ) |
| (4) |
In
BIOS setup menu, we must raise
DRAM Voltage to make it more stable.(2.7
V recommended ,2.8V will be more
stable ) |
| (5) |
Raise
CPU Voltage if you overclock it
to reach DDR 466 ( See settings
hereinbelow) |
|
|
| |
Following
Motherboard are already approved with better
performance with appropriate setting |
| |
|
These
M/Bs we tested can support DDR466, for
your reference.

What
TwinMOS Suggested |
| |
|
| 1.
|
To
reach average or even better performance,
we suggest only 1 module (256MB/512MB)
on motherboard since most of the
motherboard design is not for
such high speed overcooking purpose. |
| 2. |
Please
get the most suitable motherboard
we recommended AS ABOVE LIST with
TwinMOS DDR 466MHz , contact your
motherboard supplier to reconfirm
if their product is designed with
such a high speed over clocking
function. |
| 3. |
