Question about ECC RAM
I have a GB 8INXP w/ 1GB DDR RAM in it (PC2700). Sometime I get
program errors saying something to the effect that one thing was expected, but it received another and that the particular part of the memory "couldn't be read". The main program I get this in is ACDSee, but I have seen it every now and then in other. In ACDSee, it happens when I am renaming, copying, or moving a larger amount of files, greater than 100 or so. My question, is would it be better to go with ECC/Registered memory for my system? I heard that large amounts of non-ECC memory were more prone to these kinds of errors. I have the Corsair XMS memory. Thanks!

The memory errors you describe are not necessarily problems with the physical RAM installed in your machine. If a poorly coded application attempts to read sections of your RAM that it does not have permission to, it will give the error you describe. Test your RAM with memtest86 overnight. If it lists any errors, then try retesting with a single stick of ram to isolate the bad one. If no RAM tests bad individually, then you may have issues with the sticks not playing well with eachother. When using large amounts of unregistered RAM, they can be picky about the timing. If all RAM tests bad individually, then perhaps the memory is being overclocked. Lower the timings and/or clock speed of the RAM until it passes all of the memtest86 tests. ECC RAM isn't required to have a stable system. (i.e., the problems you describe should be able to be resolved without having to resort to ECC RAM). On the other hand, if you have a system which absolutely must provide the highest uptime, like a server, then ECC is recommended. -WD |
