GTX960 only 31K PPD?

[AOrsini]

Hi All,

I've been having a hard time figuring out what is bottlenecking my PC so much. I just got 2 new GTX960s and put them in my 790FX-GD70 mobo, 8GB RAM, and am only running ~31K each PPD meanwhile my other PC is pumping out 122k ea. 960... Where do I begin...? Please help! We're on a mission to break into the top 100.

Welcome to the forum, AOrsini.

Without more info - like log - we can only guess. First thing coming to mind is new or mistyped passkey and/or username, causing a new no-QRB qualification period for said combination. You may also get older core_15 WUs occasionally. Those have no QRB, thus earning much less on a 960.

Boy do I feel dumb. My FAH didn't have my passkey in. Problem solved! Is there a location on these forums where how to fine-tune a system for max PPD is discussed?

There's no one place ... Pretty much the whole forum gets discussions like that. The bottom line on many discussions is that any tuning you do makes a really small change to PPD, especially since the ppd of one project is often + 10% from another project and the projects are randomly assigned.

Remember, Stanford is as interested in maximizing overall performance as you are in maximizing individual performance, so the client is designed to use setup defaults that work best on your system.
