Hello. I am trying to upgrade a ThinkStation S10 to 6GB of memory by adding 2x2GB memory
sticks. The S10 came with 2x1GB pre-installed.
When I add the two new memory modules, the computer gives what to me sounds like a 1-3-1
warning beep sequence and fails to boot. No error shows up on screen ---actually, there is no
monitor input at all.
I am pretty confident the memory modules are of the correct type (DDR3 1066 PC3-8500,
by OCZ Technologies), and I have tried all possible combinations of the modules on the
motherboard, just in case placement makes a difference.
What am I doing wrong?
Other diagnoses that came to mind are: (1) one of the modules is faulty ---although I have no
way to verify that as I cannot run a memory test; or (2) OCZ memory is incompatible with the
Thank you in advance for your help.

welcome to the forum!
the S10 requires 240-pin 1.5V PC3-8500 1066MHz DDR3 ECC SDRAM UDIMMs. to the best of my knowledge, the S10 requires ECC memory and your OCZ might not be ECC. without knowing the part numbers of your modules, it's difficult to say if you purchased the correct memory.

Your best choice is to go to a memory provider that has a good web site to pick the memory you require for your ThinkStation.
Here is the link to CRUCIAL's web site for the S10 memory products:

Depending on the OS installed on your S10, you may find that not all of the new memory will be seen. This is normal. The amount of memory not seen will depend on the type of video card and how many additional PCI adapters you have in your ThinkStation.
Have a great new year!!!

Hello all, and happy new year!
Thank you for all the previous messages. They were all very helpful. Here's a brief
update on my attempt to upgrade to 6GB of RAM. I followed your advice and purchased
4GB (2 x 2) Kingston modules specifically made for the S10. The model number
is KTL-TCS10/2G. I installed the modules by populating the memory slots exactly as
indicated on the manual. But when I tried to reboot the fans started spinning... And they
kept spinning without nothing else happening. I also tried to swap out the Samsung
modules the computer came with and tried to reboot with the Kingston modules
alone, but I get the same results. I am missing some key step here. What am I doing
wrong? I am completely at a loss.
Sorry for pestering you all about this.

try each of the kingston modules by themselves in slot 0 (the lowermost slot) to make sure each one works.
on a side note, i can't imagine why you'd still be having problems even with system-specific memory. i checked kingston's specs on the KTL-TCS10/2G and everything looks correct.

After many weeks, finally I have some good news to report. It turns out one of the memory modules I received was defective. Althought it took a while, I managed to exchange it for a working one and installed my 4GB of DDR3 EEC memory successfully.
I'm a much happier camper now. In spite of Vista x64, my Thinkstation is a lot faster and more responsive now. Thank you, Erik, and all the others who helped me out.
The only drawback is that now Vista x64 crashes a lot more frequently than before ---at least once a day. I am hoping that a BIOS update will fix this.

drrexx - glad to hear you've made some progress!
vista x64 shouldn't crash more given more memory. are you 100% sure that the other module isn't defective, too? i'm not. if the modules were manufactured within the same batch then it's possible that both were defective, albeit one less defective than the other.
i would pull the module that didn't get replaced and see if vista still crashes. if not then request that module to be replaced, too.

if your hunch is correct, i'm not sure what else in vista x64 could be causing an issue besides the above.
it's worth a try anyway.
