Hi, recently upgraded my PC and have been playing around with RAM overclocks.

Im having an issue where the Infinity is running very slowly, 914mhz. See pic

I have an AMD 3600 and Patriot 2x8gb 4133Mhz (clocked @3666mhz).

I heard that running the RAM speed over 3800mhz stops the infinity fabric from running 1:1. Which for gaming i heard is worse than having +4000mhz (i couldnt get my pc to boot at 3800, thus the 3666)

Any ideas what is causing the 900mhz though? Maybe a bios setting, though im not sure what infinity shows up as in there :(

Cheers,
Zola

Respectable
Go into Bios , search fclk and set it to 1833. Set ram to 3666.

Additionally there should be a setting ( perhaps advanced setting), which sets the divider UCLK:FCLK:MEM.

I do not have a gigabyte-board, therefore search for your own, please.

Hi Zoladex. It's actually over 3600MHz that the ratios changes. Try running that RAM at 3600MHz and see what happens. Not 3666MHz.

3600mhz did the trick thanks!
I assume people i watched had overclocked there Infinity? Any ideas on performance 4133mhz w/2:1 vs 3600mhz w/1:1? Regardless im a happy man! cheers.

I'm happy it works fine now! Just leave it at 3600MHz. The 1 fps difference you won't even see it ;p
