960T with a 970a-ud3 overclock help.

post #1 of 7
Thread Starter 
Long time listener, first time caller. I recently purchased this mobo/cpu combo for a computer I built. I also bought a decent heatsink/fan for it. I dont know where to start so here goes. I am trying to overclock this bad boy, but I want to include the FSB in the equation (as I understand it will deliver better performance). I can get to 4ghz by simply jacking up the multiplier, but I have read that isnt the end of things. but if I try to got from 200 to say 220 on the FSB, I get the black screen saying that I cant boot because of OC settings. I see most everyone here is able to adjust the FSB. Not sure what I am missing here. I havent messed with voltage because I havent seen any concrete info on what to adjust. Currently the vcore runs at 1.475v base. Basically if anyone has experience with this mobo/cpu combo or sees an obvious issue I have missed, I would appreciate the feedback. Thanks in advance

Did you disable turbo core first?
I have that same combo (Spare Parts) so give me more specs like RAM type and amount andI I will give you my settings for ballpark figure.

I am using gskill-ripsaws ddr3 1600 4gig X 2.
Raidmax 530w PSU
Radeon 6770 gpu
Cooler master hyper 212 plus heatsink/fan

Guess I should put a rig together to make it easier in the future.

I havent disabled the turbo core, but I will def do that before my next trip down the rabbit hole.

I havent messed at all with the memory side either but I understand that may be a good idea, just need to know more about how that works.

Thanks again

Increase CPU-NB voltage and NB voltage. Also disable turbo core and then reboot back into the BIOS because on this board, at least the 990xa-ud3 which has the same bios, the voltages are wacky until TC is off.

Thanks for the advice all, Cmac nailed it. I think where I went wrong in my adventures was two-fold

1) I had the power saver options on

2) I had not touched CPU NB voltage or the CPU voltage at all.

Cmac threw me some settings for my board and CPU and it worked like magic. Kutos and thanks to you.

I will now have to research this stuff and try to understand the voltages, which seems to be my weak point. Thanks again, but I wonder if I will now become a hopeless O/C addict.

That's because when you increase the HTT you also increase the following:

Nortbridge Frequency (IMC)
Hyper Transport Link (HTL)
RAM

So, you'd need to either lower the multipliers for those given things OR increase their voltages. I'd doubt at 220 the IMC or HTL would be causing significant problems; doesn't need any voltage increases until 2500 or so.

That leaves memory. Either increase the timings or decrease the multiplier to have it run @ 1333.

And, as far as increasing the HTT makes things faster; at least on my system, it is a myth. I cannot find any evidence, outside margin of error, to substantiate such a claim.
