Pentium 4 630 & GTX 550 ti - PCIe bandwidth problem?

Postby clckwrk » Sat Aug 26, 2017 2:54 pm

Hello everyone
I´m relatively new to folding and after folding on my normal work PC I want to build a low cost folding PC. I´ve found an old Pentium 4 630 computer lying around and now my question is:
The motherboard is apparently just having a PCIe 1.0/1.1 x16 slot and my old GTX 550 Ti wants to have a PCIe 2.0 x16. In prinicple it should work, but does someone of you know if I´m introducing a bottleneck into the system by planning it like this? The bandwidth of the PCIe 1 x16 should be near a PCIe 2.0 x8.

How much efficiency would I lose due to this and will it affect the perfomance so much that building it like that won´t make sense?

Thank you for taking time to answer my questions.

Best regards,

The PCIe bandwidth won't be the problem, but I'm afraid that the P4 might not be able to prepare data for the GPU fast enough ...
