What benefits are you getting with the F15r compared to the official F14 ?
what Pros and Cons do you find between the two
Way more RAM timings, like slew rate and tcke. The opening boot screen, where you choose go to bios, where to boot from, etc, is arranged better (my monitor, when starting up the computer, says HDMI in the bottom right, and on F14 it blocked one of the options, while on F15r, they clearly moved around the options so it won't get blocked by things like that).
It also adds fastboot/ultrafast boot. I think those might just be for windows 8. I played around with them and they did change a few things - i think all it does is change how fast your opening splash screen is, which is when the computer is initializing and detecting what's plugged into it, which doesn't take long at all anyways.
For RAM overclocking F15r is wayyy better than F14. The latest official beta bios on gigabyte's page, the F15q, sucked, anytime I applied settings, they wouldn't stick. I think what they tried to do was like if your overclock was unstable, they'd just use the last successful boot, but you weren't exactly clued in to when your overclock was unstable, and it didn't seem quite right, so what happened was basically I never knew if my overclock changes were being applied or not, and just to be safe I'd have to cmos reset anytime I wanted to set different bios settings and it really sucked. I mean it's more than me just being cautious, there was something else going on where even very minor, clearly stable bios changes being applied, simply wouldn't stick.
On the Z77X-UD5H, can you set different RAM timings to each channel? I'm trying to do that but it's not really sticking. Halp.
For reference, I'm using 996902s in one channel, 996826's in the other.
996902 = mushkin blackline ridgebacks 2000mhz CL7-10-8-27 1.65v (verified 35+ hour stable on vtt/imc/pll 1v/.875v/1.6v email@example.com)
996826 = mushkin blackline ridgebacks 1600mhz CL6-8-6-24 1.65v
They are actually both identical RAM ICs (XDZxxxA3G-A, with the 2000mhz ones being 014 and 1600s at 015 so same ic, made the next week). I think the new kit actually isn't as good an overclocker as my 996902s (which overclocked better than my previous xdz's anyways) but I was trying to set different timings on each kit to hopefully make them work but having difficulty.Edited by Belial - 4/6/13 at 12:43pm
