IF the decision/discussion becomes finalized 64bit OS for the GTX750 Ti, or 'non available WU's for 32bit OS, can you, let us/me know, I would only switch to protect my folding GTX 750 Ti investment. I want this to fold 24/7 reliably.
Thanks
As Joe has said, 32-bit windows is still supported but as projects grow loarger and largen, some cannot be completed without access to 64-bit memory. (The deserialization process run during the WU setup may require more than 2GB of addressable memory which is the limit for 32-bit processes. This is not an issue that' can be addressed by installing a new client.
In fact, some projects for Core_21 are available for 32-bit windows. Many projects have an assignment restriction requiring a 64-bit operating system. This means that: Yes, you can continue to run on 32-bit windows, but you may find times when the only projects available for assignment to your GPU have no more WUs to assign although there are plenty of WUs which could be assigned to a 64-bit OS.
This is not just a Windows issue. Donors who run LInux run into the same issue. In fact, at one time, only 64-big Linux was supported. Some projects are small enough that they can run on 32-bit Linux so support was added, but WU availability is much more limited.
