Hope this one doesn't let me down on LN2.

 

Cinebench:

4500 @ 1,15 Volt

4750 @ 1,250 Volt

4875 @ 1,330 Volt

 

HWBot Prime 5 GHz @ 1,385 Volt

I noticed some in this thread using an input voltage of 2.1v

 

Is this a safe voltage for 24/7 use on water? What is a max safe VRM temp recommended for 24/7 use on water?

 

Thanks.

Yea 2.1 is totally fine. My max for air/water is 2,3.

 

On my 5930k, I am stable at:

 

4.5 @ 1.32v

4.6 @ 1.38v

 

I am running 1.95v input voltage. If i move towards 2.1 or higher will that help me use less core voltage?

 

I would like to see if I can get 4.6GHz at closer to 1.35v. And, I would like to see if I can bench 4.8GHz at 1.45v (currently takes around 1.48v).

 

Thanks for the advice.

I don't think it will affect the actual voltage needed but I could be wrong.

S-spec: SR20Q

is my new 5960x

my "old"5960x (costa) is a suxor :-/ 4375@1.45v

Have tested four, first three were about the same, needed ~1.33V for CB R15 4500MHz. One L430C145 and two L424B979.

 

Last one is a costa rica 3429A714. Does CB R15 4500 MHz @ 1.245V.

5060-5080 xtu 1.44v 5ghz+ uncore(1.35v) 2800 tight mem

http://hwbot.org/submission/2834262_pulse88_xtu_core_i7_5820k_2051_marks

score is 5040 but i have got it higher with 1.44v.

5400 hwbot prime 1.44v 5100+ uncore (1.35v) 2800 tight mem

http://hwbot.org/submission/2834289_pulse88_hwbot_prime_core_i7_5820k_7923.42_pps

Done with weak single stage.

Scale with cold and voltage. i cap the voltage to 1.44v before i do cascade runs.

cores and imc is very strong best haswell cpu i tested yet.
