2080 Ti SLI Overclocking question

Hi,

 

I got a question regarding overclocking.

 

It seems that one of my cards can do 2115Mhz OC and the other one 2040. Will the clock increase if I water cool them? I'm unsure about turing and the cards are behaving differently with same overclocks applied to them.

If they retain the say steps like the 10 series, clocks could go up. Are they hitting power and voltage limits?

 

are you benchmarking or just playing a game? Should be able to see the same clocks out of both if benchmarking.

Benchmarking Heaven 4. I benchmarked using The Division also.

 

I got +160 applied to both, but one goes to 2100 more or less and other one goes to max 2040 and drops right away to 2025 and once temp is slightly higher it drops below 2000. The other one stays rock solid over 2070 at all times.

Well there are plenty of issues already but the only way to really say is the setup. 

 

Are there two slots between the cards? Fans already on max? What do they boost to default and with max power/voltage?

 

Are you watching the limits on power/voltage/temp?

2 slots between cards, fans at 3700 RPM max, default I think it's 1860 both when in SLI, power and voltage cranked up to max.

That answers about half.

Are there two slots between the cards? "2 slots between cards"

Fans already on max? "fans at 3700 RPM max"

What do they boost to default and with max power/voltage? "default I think it's 1860 both when in SLI" rest answered in the 1st post....

 

 

Are you watching the limits on power/voltage/temp? = they obviously hit all limits since it's all cranked up...

Well if that’s as detailed as it’s gonna get, sure the clocks can go up on water. As the hundred of videos ltt, gn and jay have done this past month.
