Damn that's good for the voltage! I can't get my FX 6350 stable below 1.46v! But I haven't tried everything you did. ALL power savings are off, cores unparked, it runs at 4.6GHz constantly because if not there are issues with performance. Cooled with a Noctua NH-D15 it's Prime95 stable for 6 or 8 hours. I forget. THe motherboard is an absolutely amazing Asus Crosshair V Formula Z.

I'm planning on selling this board and chip within 2 weeks to be replaces with an Asus Z97 Pro and 4670k, but seeing your thread tempts me to mess with the overclock some more!

When I first got the chip I tried everything possible and it was stable at 4.7GHz using 1.52v while 4.8GHz was unstable but close. After some time became unable to run that. and 4.7GHz is not stable at any voltage. frown.gif I was thinking of attempting to delid as it is possible with a soldered chip, but it was too risky. Even on this voltage I can't use Prim95 unless I put case fans at max or else I get a shutdown from the motherboard at around 83-88c even though the settings for that are disabled and the CPU shouldn't do it until 90c. I'd like to keep it under 80c anyway.

Any suggestions? Should I try FSB 230? Above 2400MHz NB and HT doesn't work for me either.

How on earth are you able to use that voltage though!? I've spent days and days learning about every setting and voltage, trying recommend and not recommended, tweaking every voltage setting and testing for increased stability. But All it's come down to is I need 1.46v to run 4.6GHz. frown.gif

I'm definitely going to give this a shot. Right now actually.

chokes will cook but vrms are cool when you are on water

Nope. I just can't do it. No matter what settings I use it still needs 1.467v Even 1.463v isn't good enough. Errorod out in 18 minutes. BUt I didn't test what has been working... maybe it's become unstable too. frown.gif Bummer.

Try lowering clocks and voltage, As your cooling is limited or the bin is bad you will need stupid volts for extra GHZ
If the GHZ scales reasonably with the voltage increse then go for it

Well if I lowered clocks then there would be no point would there. It's already a massive bottleneck for my 970 and was for my 770 too. Needs to be as high as possible. It was maxing out at 86c in Large FFT though it usually settled around 83c, that's 1.463v though. I use 1.467v. The crazy voltage wall comes at 4.7GHz where I have to use 1.55v or something absolutely freaking nuts to get it stable. I feel like the voltage requirement working upwards like a wave coming at me. The voltage required is increasing ever more rapidly. Good thing I'm selling this chip within two weeks.

What is your experience with the CPUNB? For me it has no play in the max overclock for the voltage or anything really. Perhaps slight stability increase but it's not enough to let me lower voltage by a step going from stock 1.19v to 1.30v. I've tried up to 1.40v. It just makes extra heat.

Also, will running the Northbridge lower reduce my RAM OC potential? I'm trying to hit 2400MHz on some of that good Samsung 30nm 1.35v. (What's the official name? Samsung Green something LP or Black?? Wonder/Miracle RAM sounds cheesy AF)...

I don't think it's capable though actually. IMC is not strong enough for 2400. frown.gif

Keep CPU nb on stock voltages , if your frequency is 2400 on nortbtdge or lower it should be 24/7 stable
Haven't have a time where increacing cpu nb gives more stabibility

but if you look at others on the fourm they said increacing it can give stabibilty, I don't think it does though

If its no point in clocking down then dump the 970 motherboard and dump your current cooler for a custom loop and 990 mobo thumb.gif
970 Motherboards are only good for stock specs

Running northbridge lower has nothing to do with rams overcloking potential, but northbridge has to equal to ram speed or be higher than ram speed

If you want to overclock ram, you need to have good timing skills to be having great clocks, other wise your ram oc will be limited.
Keeping frequency stock and lower CL is easy and fast.
Keeping timing stock and increacing fsb is also easy and fast

No no, GTX 970. I have a Crosshair V Formula Z 990fx. The best AMD MB in existence.

Dump your current cooler for a custom loop. 70C on 1.48V is insanly hot.
Could do at least 1.5V wihout going past 60C on water

(Well if I lowered clocks then there would be no point would there)

Or go for a 9590 9370
As they will be golden and you will be clocking (1.44V for at least 4.7GHZ stalbe on prime)

Either way would work

You'd probally don't have enough cooling for 9590 or 9370 either so lol

Also note that 1.47V is up there for a air cooler, its about the max volts a good air cooler can do on a 8 core amd cpus.

I'd be really happy with 4.4 4.5 on a air, since the cooling is limited there is not much to expect

Nope I'm dumping it for Intel. It's nowhere near what I need at this point. I'd literally need 5.5GHz to even "cut it". ALready though about this and made a thread on it.

I'm keeping the NH-D15 too because I like silence and CLCs are not silent. They've got a pump and fans blowing through often horribly designed radiators that are all pretty crappy for noise. All the same generic radiators. When I go water I'll get a real water setup, not a CLC.
