Bringing up a GTX 460 host
Inspired by the thread GPU Price performance curve I included a Gigabyte GTX 460 of the SOC flavor in a new PC I built on October 7, 2011.
In general the experience has been good, but I did hit a number of issues and thought that as others not yet initiated into the use of CUDA might find it interesting that I'd start a thread here. I'll pose some observations, issues, and questions that have come up in separate posts.
For background where it may matter system attributes include:
- Windows 7 Home Premium 64-bit
- Z68 motherboard with 8 Gbytes of RAM installed
- uses the Z68 supported Intel Smart Response function to provide caching of the main, rather slow 750 Gbyte hard drive by a small 20 Gbyte SSD drive (I conservatively chose the expensive Larsen Creek model Intel pushes for this function)
- i5-2500K CPU, running stock 3.3 GHz clock and voltage so far (may undervolt later for power savings)
- the specific GPU is the Gigabyte GV-N460SO-1GI
- the power supply is a Nexus Silent 430, rated at 430W total, of which 396 is supposed to be available at 12V, divided among four rails. Claimed efficiency is over 80% across the full range of interest, with a broad peak hitting 85% centered almost at 50% of rated output.
