I am trying to upgrade a new Gateway SX2803-US20P with 2 addition 2 GB modules.
Based on the Gateway specs modules are: DDR3-1333/PC3-10600
The memory modules that came with the machine are marked
Using the standard memory and CPU-Z ver 1.59
Type = DDR3, Dual Channel, 2096 MB
Timings = Freq 532.0 MHz, 1.2 FSB, 7-7-7-20-60
Based on Crucial's advisor tool: DDR3 PC3-8500, DDR3 PC3-10600, DDR3 (non-ECC)
and suggests: CT2297560
Specs: DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.5V • 256Meg x 64
I purchased 2: CT25664BA1067 (2x2GB)
Specs: DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.5V • 256Meg x 64 •
When I either add the new modules or use one alone. I get a continuous beep during POST and nothing else.
Is there a difference between these two that would cause this difference.
Solved! Go to Solution.

Unfortunately, I can't access your mobo info because the only place it can be found is on your PC!
Anyway, a few others have reported a similar problem (eg, beep and no post with both modules installed); however, when they tested 1 module by itself, it usually worked. Now you said you installed 1 module at a time but did you remove all of the old ram and then test just 1 module or did you leave the old ram in and then test 1 of your new modules? If the latter, remove all ram and install 1 new module and test it; repeat for the 2nd module.
So before I go any further, please verify what you have done and/or do the retest as described. I don't want to write a book if it can be avoided. BTW, your current RAM is operating at 1.5v; correct?
Let us know.

Just to be sure I re-tested the crucial memory each of two sticks, one at a time in each slot. same result.
The SPD tab on the CPU-Z utility says that the existing memory runs at 1.5v so I assume that is what is happening.
A ran the crucial scan utility directly on the machine,
it says the machine is:
Your SX2803-25e System Specs
Scan Id: 14971FCE31D926C3
and it recommends
the mobo is simply listed as a MB DIGI 43L, other research indictates its a Gateway sx2803 mobo

So, in summary:
You used the Crucial Advisor and it recommended CT2297560.
You used the Crucial Scanner and it recommended CT1843267
You bought CT25664BA1067(which is NOT on the recommended list for the SX2803-US20P Desktop)
Just curious, did you buy the RAM from Crucial directly or was it through a reseller? Either way, based on the detailed testing you have done, and the lack of detailed specs available for scrutiny, I can only recommend that you return it and make another purchase based on Crucial's recommendations.

The model purchased was what newegg offered that met the specs.
Can anyone tell me what is different between the two crucial recommenattions and the model purchased?
they all have exactly the same specs that I can see.

Hello again rcmerlin,
I was hoping someone would respond so I could also learn something today as well. I agree that they all look the same based on the general data available; however, they ARE different... otherwise Crucial wouldn't need so many DIFFERENT and UNIQUE part numbers. Here's a sample readout from one module on my PC (note: images must be approved before they are visible):
Most people (myself included) rely on Crucial's recommendation to avoid trying to understand the unique differences between modules that look the same based on the limited specs. that are available.

Those part numbers are for the same memory modules. They are guaranteed compatible so it's possible you are having the issues due to a fault.
I would recommend trying each new module one at a time in the system to see if one module is faulty. If there is an issue with any of the modules we can exchange them for you.

Thank you for you input.
Just to be clear. your saying that all three of these are actually the same?
I have tried each module individually, as a pair, and in conjuction with the existing memory.
What do I need to do to exchange them?

OK got the skinny from Crucial tech support (many kudos to Shawn).
Some memory modules come in low and high density (not stated ANYWHERE!)
The rqmt for the Gateway SX2803 is LOW (aka 16 chips not 8), hgh will not work.
So if you just look up and buy on specs, your may (I did, twice) get high density modules.
He is taking care of it. Amazing Christmas Joy. Thanks Shawn
Also, Shawn told me that the tools report CT (catalog numbers) which are mapped to machines.
Thus you may have different CT numbers which are in fact the same. Confusing for me, but he says
it helps make sure the correct memory is tagged for each machine. Smart for them.
Lesson learned: use the Crucial tool and buy directly from them.
