- Looking at the specs of the S10, it reads "Up to 4GB DDR3 PC3-8500 ECC UDIMM"
Does this mean that it only supports ECC memory? Would non-ECC RAMs work too?
the S10 actually supports up to 8GB and might even support 16GB once 4GB PC3-8500 modules are readily available.
lenovo's original modules are ECC but i'm not sure if the S10 will accept non-ECC modules. even if non-ECC modules were compatible, i personally wouldn't buy them simply because error-checking components are one of the benefits of having a proper workstation. you might as well just get a desktop otherwise.
- From the picture it looks like IBM is using a propriety board and own brand heatsink. However, I would like to use a different heatsink, something bigger and a different fan (such as a Thermalright tower heatsink). Would it be possible?
yes, this is possible. however, i can tell you from personal experience that the OEM thinkstation heatsinks are of very high quality, very high efficiency, and very low acoustics. i'd be very surprised if an aftermarket heatsink can best the OEM heatsink in all three categories.
I think Quadro FX1700 with 512MB memory should be enough to work with Solidworks and some rendering job. What do you think?
according to nvidia's chart
, the FX 1700 looks like it would perform quite well in solidworks. unless you're rendering 1000+ part models or need real-time rotation ability, i'm sure the 1700 would suit your needs.
i opted for an FX 3700 because it has 4x faster throughput than the 1700, is on par with the 4600, and runs quieter than any quadro card before it. plus, it can use up to 2GB of shared system memory when needed, giving 2.5GB total. in my opinion it's the most cost-effective quadro card available.
