The QM2000 has on-board memory which holds the QM operating system, show
data, and frame data. Up to 512MB can be addressed. This is a lot of
memory (over 60,000 standard 30K frames), but on the other hand, if you
use many raster frames, or computer graphic animations created by one of
our conversion programs, the memory can be quickly filled.
For example, you may require more than 256MB of memory if you are using
a lot of Raster frames, or computer graphic animations created using
one of our conversion programs, such as
Lasershow Converter MAX. The, the 4-minute-long Revelation demo
is approximately 8,000 frames, which takes up about 50MB.

cost to upgrade from the standard 256MB, to 512MB.
The ability to use 256MB was added on May 10
2001. The ability to use 512MB was added on December 20, 2001. All QM2000 boards with serial number
higher can use up to 512MB.
However, if your serial number is
4199 or lower, then you may have older firmware (the QM2000 on-board
operating system). To check this, select the Help/About menu in
LD2000 or Showtime, click on the "Boards" tab, and look under the
"Firmware date" column.
If the date is earlier than December
2001, and you want to use 256MB or 512MB, you will have to send your QM2000
board to Pangolin so the firmware can be updated. You would have to
pay for shipping both ways, plus $50 for the update.
In addition, we strongly suggest you
order a your memory module from Pangolin at the same time.
This ensures that 1) you have the correct type of memory, and 2)
your board is tested with the new memory. For current pricing of memory modules,
A number of potential customers have asked about how the QM2000 memory
first question often asked is whether they can use the host PC
computer's memory. The answer is "No". This is because the QM2000's ColdFire processor only accesses the
QM2000's on-board memory for
displaying laser shows. Your PC could have hundreds of megabytes of
memory, and it will not affect the QM2000.
The next question is whether they can install their own memory modules into the QM2000. The answer is "Yes, but we would prefer you to use memory obtained from
Here are the details.
The QM2000 uses single-sided
(sometimes called "single-rank") dual in-line memory modules (DIMMs).
The photo at right shows the front and back of a single-sided DIMM (click photo
for an enlarged view). Note that there are no memory chips on the
You can use double-sided DIMMs, but
the QM2000 will only use half the memory. For example, a double-sided
512MB DIMM would only provide 256MB to the QM2000.
It can be hard to tell whether you
are purchasing single-sided or double-sided DIMMs, without removing
the DIMMs from their packaging and turning them over to see if there
are chips on the back. There are also DIMMs which are electrically
single-sided, but physically double-sided. Therefore, we recommend you either purchase
from Pangolin, or that you purchase from a store where you can return
the DIMM if it does
not provide the memory capacity you need.
Pangolin uses Kingston
Technology brand memory. In our experience, Kingston
offers the highest quality and best reliability. In addition, the memory that we obtain is
specially built by Kingston to our OEM specifications. We recommend
that you obtain memory directly from Pangolin.
install non-Pangolin memory modules, then they are responsible if there
are any problems with the memory. For example, if a QM2000 board is
malfunctioning, and we determine the problem is in customer-supplied
memory, we'll install our own memory module and charge for the module and
for the repair. Of course, Pangolin-supplied
memory modules are fully covered under the LD2000 warranty.
