ROG Crosshair VI overclocking thread - Page 946

post #9451 of 17850
Ok here is a Screen grab of the throttling I see when I BLCK OC:



Under load it throttles back from 4050mhz to @3500mhz, and I have no idea why. It is running hot, but not crazy hot. Voltage is set at 1.44, and under load drops to 1.41

I have the same results on no matter the strap I use. I have run the CPU speed up as well, I have the same results running 3.9 as I do 4.1.

Any idea what is going on here? Is there something I need to disable in the bios? I am 99.9% sure this is not a thermal or power limit issue, I am really stumped on this one.

I can run 4.1 at 1.42v stable, I can run 4.2 @ 1.46 mostly stable... It will bench, game and work fine, but will fail stress tests after about an hour.

Cooling plays a lot bigger part in the OC range of Ryzen CPU's than most people think. Ultimately the goal is to keep Tdie below 83-85'C, a good custom loop with a very good TIM helps a lot.

As far as I know there are no (Or very very few) 1700's that hit 4.1 with lower voltages.

What I did was use the factory back plate backing like you did and put it in-between the MB and the EK gasket (Center removed) and that worked very well.

I also contacted EK and requested the mounting screws from the "EVO AMD" waterblock. These screws attach to the water block's bracket and use the factory backplate. I highly recommend you do the same, all my issues disappeared immediately.

i have asked them too, for those mounting screws to the original backplate, but they just said that they will send new improved rubber gasket smile.gif
for now i use modified screws with original backplate tongue.gif

Your tctl is 95°; it is throttling as designed to happen at that temp.

How long can you run prime95 large fft before you get an error?

It does not throttle at 41.5 x 100 at that temp?

At 4.1 at least 2 hours, never let it run longer than that. At 4.1 about an hour.. sometimes 50 min, sometimes 65 min, etc.

It should be.

Good stuff! Can't wait to get my 1700. You don't think an H100i is enough to cool it?

Maybe you know.. but on a 1700, without the +20'C offset, does it throttle at 75'C Tctrl or is it still 95'C tctrl?
