Hi
I've been trying to use the BIOS (revision F8) of the H61N-USB3 to overclock an i5 2500k, but I'm not seeing an increase in clock speeds with Prime95. I've set the CPU Clock Ratio from anything between to [35X] to [37X] (37 is the limit for some reason, which was disappointing but I'll live with it I guess), but RealTemp shows it maxes out at 3.4Ghz when running Prime95.
I've tried setting the Turbo Boost Tech to both "Enabled" and "Auto", but it makes no difference. Setting lower multipliers seems to work fine, but anything above 34 does nothing. Am I missing something really obvious?

Not sure as I haven't overclocked since X58 boards, but you sound like your overclock is being overridden by turbo. Try disabling turbo and see if it works properly.

Yeah, I had the same thought myself, but disabling it altogether just runs the clock at stock 3.3ghz, no matter that multiplier I use, high or low.
Here's something else weird I noticed; when I press the "XS Bench" button on RealTemp the clock does little jumps all the way up to 3.5 and once it very briefly went up to 3.6ghz. But on every other benchmark test it maxes out at exactly 3.4ghz.
I've raised a support ticket with Gigabyte.

Have you updated to the latest BIOS?
Maybe try a default setup by loading system defaults and make sure all of the standard clocks are working correctly.

ps, are you making sure to save BIOS setting on exit?
-
Yep, the board already had the latest BIOS (F8) and I've tried the defaults and all looks fine. And yes, I do save the BIOS when I exit :-P
