i7-7700K and negative offset.

[anterior]

Hello!

 

My Scythe Fuma doesn't seem to handle my super warm i7-7700k too well at anything above 4.7ghz. It's one of the earlier chips so it runs super hot no matter what I do without delidding it but I still wan't to stay within decent temperatures with a little overclock. Since I don't want to have my CPU run at constant voltages I am choosing to overclock with a negative offset since for some reason my CPU wants to run at almost 1.4volt at 4.7ghz at auto offset values.

 

At 4.7ghz @ 1.17 manual voltage my CPU runs at 80C heavy stress test programs and I'd prefer to stay under that while also having my vcore drop in idle. Would it be safe to have a negative offset voltage of like 0.070 which would make my chip run at 1.2 voltage under load @ 4.7ghz? I have heard people don't generally want to mess with negative offset values but I don't really see any other options.

 

What do you guys suggest? And thanks in advance.

I had to delid mine to get it stable at 4.8ghz and 1.275 volts.  They are hot little f'ers. 

What does voltage go to when you set it at 1.17?

Hello and thanks for the quick reply! Yeah they are and it is very annoying haha.

 

I am pretty sure it runs at 1.2v when I've set it to 1.17 without any LLC. I got a stable 4.7ghz manual with LLC level 3 (1.18v in bios) where it handles running 4.7ghz at 1.14 perfectly fine under load, seems to be a very sweet spot temperature wise too. It just sucks that I have to resort to these drastic measures to run a slight OC without it going up in flames.

 

If anything, I doubt it'll hurt my chip running at a constant 1.14-1.18 volt?

Yeah it kinda sucks.

What cooler are you using?  Mine is on a Noctua D15 and it still will go into the 70s under constant load.

I am using a Scythe Fuma.

Sorry, you did say that before.  Yeah they are the same style of cooler.  Without the delid mine would go into the 80s too under constant load or P95 testing.

No worries. Yeah that's very shitty, perhaps I should just suck it up and delid it.

Or sell it and upgrade...

Yeah that's true, probably the better decision at this point to be honest.

I recommend de-lidding, as the 7700k is within the best per thread performance CPUs available. I managed to get my 7700k at 5GHz at 1.39V maxxing out at 76c on a NH-D14

Thank you! I tried it, the speed is very fast. I will reset and try lower vcore, and should also download more RAM cloud memory to the computer to speed up the computer faster!
