Overclocking Motherboard Issue...

[Drannon86]

Hey Everyone,
Here's my setup:
A6-5400K
GA-F2A88XM-D3HP
G.SKILL Sniper DDR3 2400MHz 2x4GB Ram F3-2400C11D-8GSR
w/ Timings C11-13-13-31 and Voltage of 1.65V.

Here's my current overclock: A6-5400K - 4.0GHz on the CPU side, 1100MHz on the Graphics side, and have the ram clocking at 2133. I can't raise the BCLK on the motherboard even with no overclocking. I tried adjusting the voltage on the north chipset by a very marginal amount (.125 to be exact) and that was it's own set of headaches. Maybe I'm missing something with the BCLK but I can't move it 1MHz without it basically giving my system the black and blank screen. I have tried adjusting my timings on the ram to no avail. Currently both Gigabyte and G.SKILL haven't responded to me and it's been almost a week now. So here's my question to everyone out there, how for the love of God can I get this bloody ram to 2400MHz?

There should be memory dividers you can adjust for RAM speeds. Are you trying to get to 2400 using BCLK alone in combination w/ voltages?

Please read the post before answering. I'm not changing the BCLK at all since even moving it by 1MHz makes the computer not post. What I have tried doing was changing the north chipset by .125V and it still wouldn't allow me to change my BCLK. In my BIOS, I have options just for ram and that's where I change the clock of the ram to 2400MHz and the voltage to the recommended 1.65V.

Seems like getting 2400 on your board is difficult for others as well. Since 2400 speed requires an OC of the memory controller in the CPU, could be a limitation there. Not sure though why you can't raise baseclock even 1 Mhz though. I assume you're on the latest BIOS

I'm thinking that you're right as it being the limiting factor. As soon as I load the computer up in 2400MHz, everything is super fast but full of glitches. I think that I'll have to be happy with 2133MHz even though it's not the best that I can get or until Gigabyte or G.SKILL can tell me what to do.

Found the issue. With the A6-5400K (and most AMD processors) you have turbo mode. Turbo mode is that wonderful jump the processor does from it's base clock (3.6GHz) to it's turbo clock (3.8GHz). Having disabled that, it goes smoothly and stable to 2400MHz. Can't believe that I didn't think of that before. Thank you to 1LiquidPC for the assistance.

Glad you figured it out. No need to thank me, as you got it yourself. I wouldn't have even guessed at turbo being the cause of the problem. Still, thanks for the heads up, as you taught me something new. Enjoy the 2400 speed

Back to the drawing board. I tried playing Skyrim and got through almost 5 minutes of gameplay before a blue screen. Tried again, same thing. Tried different games, same thing. The only thing I have over clocked is the ram to 2400MHz. Crap.

Just got a response back from both Gigabyte and G.SKILL. They basically told me that I won't get to 2400MHz because of my CPU is only rated at 1866MHz. When I told G.SKILL that I can go to 2133MHz, they said I was lucky to have a CPU that would do that.

That kinda sucks with the update, but it does seem that it is indeed a limitation of the IMC in your CPU. Just can't handle the 2400 speed. If that's the case, I'd keep trying to tighten the timings at 2133 as far as you can go, or are willing to go. This should pick up some extra speed. In my own case, my ram at 2666 benches higher/greater bandwidth than running at 3000 w/ loose timings.
