Hello, I've recently received my Kingpin and been having a blast overclocking it. I seem to have run into a strange problem, my results on benchmarking has drastically changed from a previous overclock the night before, into today's overclock listed below. I noticed my voltage has dropped on the card significantly, allowing the clocks to go higher, but results dropped entirely. Would would cause this problem to occur? I've tried lowering the current OC back to the previous and results drop even lower. Only thing that happened during previous night and today was powering down the PC. (Upon waking, I tried the same exact OC from previous night; today and found the result dropped, which led me to clock even higher for the current OC as of now.) This is my first time digging deep into overclocking, so please excuse my inexperience. Current OC(stable): GPU clock: 2250mhz (+205) (210 causes crash) mem clock: 8600mhz (+1600) temp: 40C superposition score: 12,412 Heaven Bench: 5256 power consumption: 140w Previous night OC(stable): GPU clock: 2160mhz (+110) (115 causes crash) mem clock: 8600mhz (+1600) temp: 45C superposition score: 13,398 Heaven Bench: 5721 power consumption: 300w system specs: MB: Asus Apex Rampage VI Apex Processor: i9 7900x - 4.6 ghz Video card: EVGA 2080Ti Kingpin RAM: 16 GB ram 2133 mhz PSU: corsair AX 1200i

Its obvious the temp change. If you hit 2250 at 40c or 45c all i can say is wow. usually it takes a lot cooler temps. keep it cool and she will perform. check out my dbase at my youtube page here --> https://www.youtube.com/watch?v=2e4fs-KdQEE

Hey TwoEvilOne, Yeah right now i'm running heaven's bench at 2250mhz at 44c. This didn't occur the first day I received the card, as it was only able to do 2150 and going up would cause a crash. For some odd reason today, I began benchmarking and was able to push 2250 where I failed to do so yesterday. Any reason on why this would occur? Also would windows instability be from a lack of power from the power supply? As I continue to push the clock up, windows begins to lock up. The only thing I can do is move the cursor, apps cant minimize, folders dont open or close. alt+ctrl+delete doesnt work. pushing the power button causes a black screen instead of shutting down. Thanks for your help, much appreciated. I've checked out your video, and will be reviewing that database for the future.

40c at what voltage? Are you using a chiller/sub-ambient solution?

If that's using the stock cooler that's a darn good card for sure to get the 2250. If the 40c is being maintained it must be pretty darn cold air where your at as well unless using a chiller but then temps should be lower yet. Also if you were running the classy tool which I assume you are did you make sure you were using the same settings? If the PC crashed and did a hard reset the classy tool would have went back to default settings.

@Dwexpress pretty much spelled it out @Foxyx, temp and voltage is the only things that affect MHz like that. Also a hard reboot would clear your settings from classic tool yesterday. Your psu is plenty large at 1200W so its a conundrum as of yet with given info. Glad you enjoyed the dbase info. Sleep is calling me meow.

Good afternoon everyone, I am only using the stock cooler that came with the card. I did download the classy tool and all I did was turn off auto, as auto seems to send up to 1.05v that causes crashing. The ambient temperature is probably 55F, as this is my daily use computer, I keep it in my room. I was just playing with the NVDD voltage, in the range of 0.8 - 0.875. I had it set at 0.875, and had a temp of 44-45C. I lowered the NVDD down to 0.8000 as of current OC. Thanks for the info and help. I'll probably make a new thread to keep up current records of OC, and see how far I can get on the stock cooler. Current OC: GPU clock: 2250 mhz. mem clock: 8600 mhz. GPU temp: 38c

i cant imagine lowering the voltage that low and achieving 2250 HMz on the GPU. But ive never tried it either. Your 140W power consumption is super low too. seems like your card is under powered due to voltage being to low. Maybe try something like NVVDD = 1.09375 V FBVDD = 1.40000 V PEXVDD = 1.078 V PWM Freq = 400 kHz NVVDD LoadLine = level 0 NVVDD OCP = Disable This should get things stable and working again for benchmarks and such. Dont leave your NVVDD that high for daily driver, it usually maxes around 1.07 ish.

Yeah, This is why I made a post about this thread, as my PC overnight all of sudden dropped in voltage. 2 nights ago: card was pulling upwards 300watts+, +110 clock Max, +1600 mem Max. Turned on pc next day with same OC nothing changed, didn't have classified tool yet. next day: card voltage only 120w, same settings. benchmarks results dropped like a rock. would it be the card isn't working right? or a power supply problem in this case? (will throw in. When I recieved the card and powered it the first time, it was also undervolting. I changed the bios to normal, restarted. let windows load, restarted back in OC mode. card began performing at high voltage.) I tried the same trick, but the undervolt still persists. For my current OC at such low wattage: NVVDD: 0.8000 ( going above 0.8000 causes artifacts) FBVDD: 0.406 PEXVDD: 1.039 (lowered it to test a higher clock speed to try and minimize artifacts. PWM Freq: 400 KHz. 1.8v: 1.8v (what happens if you change this specifically?) NVDD Loadline: Level 10 NVDD OCP: Enable (Will update after trying new settings above)

Not sure how to edit posts... But just tested new settings. the wattage definitely spiked up, now about 250w lowered clocks back down, testing clocks only. Thanks for the settings. Now that the wattage is back up, I'll play around within these settings, and see how far I can push the card. Strange that auto doesnt work as intended. if not for the classified tool, I think the card would have stayed undervolted entirely.

Heh, 0.8V is way outside of working range even for stock clocks. So what is happening - your voltage is too low, and GPU is power starved. You may think that it's running high clocks, but actually it is throttling hard, skipping frames, resulting in very bad performance. I would suggest to do full power cycle and try overclocking cards w/o touching anything in classified candies, or doing any altering for voltages. This should provide you a good baseline of what card doing performance/clock wise. Then you can try increasing volts in very tiny steps (e.g. +15mV at at time) to see if that helps. You may see just 30-50MHz stable clock AND performance increase, or more, depends on the card and particular temperatures/fan speeds/etc. Auto for NVVDD means stock default condition, and when you start 3D loading (run the benchmark/game) power managment in driver and card will kick clocks and voltages to nominal boost level, which is 2G+ for clock and ~1.05V-ish for NVVDD. When you manually override or turn off Auto, everything is altered and you are in the woods if voltage is not set correctly. So you must get familiar with what GPU voltage card needs to obtain best performance (often NOT equal highest clocks!). Be sure to take a read thru the guide for KPE RTX, might find some more ideas in it as well.

Thanks for the indepth reply TiN! I've been doing lots of tweaks between the controller and precision to get a idea of how the voltage affects clocks and speeds. I've read through your guide a few times and it is very informative. I'll continue to use it as a reference as I dive further into this. Thanks for the help all, I'll post some results in the future.

Also remember, settings from candytool are NOT reset just on at reboot, they are only reset after full power off/power cycle, when card power is shutdown.
