hi my 3080 ti was puling 320w +/- and suddenly now it pull max 307w

i repaste it put new themal pads temp is beter but not crazy 58c/92-94 temp and we can see afterburner is at 100% but TDP is only 86 %....

opn pice #2 power u can see it not the same power has the #1.. is there something wrong or shorted ? or need better cooling ?

Can you kindly post a HWINFO64 screenshot of ALL of the input power rails? You will need to expand all of the fields on the left side. First, install the latest hwinfo version, then download the "Beta" version, which is in the middle of the website under "latest pre-release" and manually extract the files to c:\program files\HWinfo
Also ,VERY Important, and this is one reason why I want to see hwinfo here, have TDP Normalized % showing. GPU-Z does NOT have TDP Normalized. TDP Normalized is a value of TDP based on the highest value of any individual input rail, with respect to its own internal power limit. This value is hard to explain, but think of it as "GPU Hotspot" temp or Memory Junction temp, which in those cases, are the hottest individual sensors giving the highest value for any specific one of multiple sensors, except this time it's a "Power limit" % exceed by" hotspot, rather than a 'raw' absolute max power draw.

I "suspect" that SRC is throttling you here. I have no idea why SRC would be 141W, as SRC is the power balancing chip, which also has its own "internal" power limit as well as individual SRC rails linking to the 8 pins (SRC1 and SRC2 ALSO have power limits!), and these rails control the "TDP" of the individual 8 pins (I am NOT talking about Total Board Power TDP!!).

SRC value is very suspect here. Usually a SRC of 141W+ happens on 450W high wattage cards, or on cards with bad power balancing or faulty shunt mods (on cards lower than 400W).

Thank you.

Do the same test you did here, with the GPU at full load, just like this.

Hi, thank you for this but you forgot to expand the power values in hwinfo.
You still have them collapsed. You expanded the "GPU Performance Limits" but this is the wrong thing to expand. You need to expand "GPU Rail Powers."

Yes, TDP Normalized (reaching 100% while TDP is only 89%) is indeed throttling you but we don't know WHICH power value is hitting its limit because you still have them collapsed. Normalized reads the "Individual" power limit from ALL of the input rails. There are two other input rails related to NVVDD voltage and MSVDD voltage that HWinfo doesn't show at all (but ALSO report to TDP Normalized, which just confuses things even more) but this is not important as this only becomes a factor on cards running at >500W power draw.

 

it says power limit yes.. so i got thermal problem ?

 

No, it says power limit, so that means... power limit.

What test have you run? Are you comparing apples to apples? Or are you comparing a benchmark to a game? Two different instances. I see your "normalized" TDP is 100%.
Falkentyne will probably have something to say about that as he understands these things far better than most around here.

 

Hi sorry didnt see you whanted rail power no english is not my first language,
im mining when not using it that how, why i detected the problem
thx guyz for trying to help me im not very good in that categories of problem
