How much to go for 24/7 980x overclocked?

post #1 of 13
Thread Starter 
At the moment, I am running the 980x overclocked at these settings:

Multiplier=21
Blk=206
Core at 4326MHZ
Memory=1648
Uncore=3296

PCIE Frequency=105
Core volt=1.375v (max "safe" spec)
QPI (vtt)=1.35
PLL=1.855
IOH=1.15

Rest, is auto.

Everything is stable and running fine.
Prime95 run for 8 hours, Linx run for 7 hours.


I can stable the cpu for 4.46 if I go for 1.398v core.
Question is, is it worth it going for 1.4v for 1.41v core and 1.38v for vtt for example, for 24/7 under water?

I don't use my main computer 24/7 ofc, only using it when I'm back from work for 6 hours max, and on the weekend I use it more like 10 hours max.

I would keep the overclock as is if this is 24/7! Temporary benchmarks/Gaming runs at 1.4v would be OK.

If it's good water cooling, then I'd say 1.45v for 24/7 is safe.

Under 1.4v for air cooling.

I've been doing alot of reading on the 980, and it looks like the consensus is saying that as long as you keep temps in check (<85-90C), you can oc these chips past 1.4v.

See this article on voltages, great read:
http://www.evga.com/forumsarchive/tm...09&mpage=1&key

I'm running 1.39 (cpu-z) at 4.5 (180*33) on both of mine and the temps are in the low 60's. I'm getting the urge to push to 4.6 and above.

My max temps are 65c on prime95/linx.
Will going past 1.4v won't damage the cpu on the long run?

You have room to go higher

How high?
When I tested for 4.5, I used 1.43 as max limit, and whet down from there to 1.41v
Max temps at 1.45v, was about 75c.

But will the cpu handle a 1.41-1.42v for 24/7, or to keep it just below 1.4v?

If it was me with that great water cooling, I'd stay at 4.5Ghz with the 1.45v.

I'd be more than happy with 75'C LinX max temps.

1.45v would be safe for 24/7?
Isn't it a bit too high?

Not with those temps.

Everyday use would hardly see anything over 70'C.
