I bought an evga rtx 3080 ftw3 ultra. Unfortunately , i cannot overclock the Gpu clock offset to more 114mhz. i tried the oc bios with 450 watt , but it still crashes if i move the slider more then 114 mhz. my power supply is 850 watt. My specs are_ ryzen 3600 16 gb ddr4 ASRock Fatal1ty B450 Gaming-ITX/ac mainboard.
I still have 7 more days to return the product.
I previously had bought msi 3080 ventus 3x , which could overclock to 104 mhz and was way quiter. i spent 100 euro more on this graphic cards but seems like nothing worth it.
Any idea what i can try? i plan to water cool the gpu after 1 year.

Maybe 850 watt is not enough

Your offset means nothing, you need to see what clock speed your GPU is actually running at. Monitor what your cards actual operating frequency is when in a game and report back. If you card is boosting itself to 2000Mhz by itself for instance, then you are adding another 115Mhz offset to it that means you are asking your GPU to run at 2115Mhz on air cooling. Furthermore, overclocking isn't a guaranteed metric and returning a product based on overclocking isn't a valid reason.

Ampere is pretty poor when coming to overclocking and the card overclocks itself and clock speeds will dip if your temps are to high, my XC3 clocks to 2000mhz by its self but does dip, you should never buy a GPU or CPU and be pissed at how it overclocks at the end of the day its not guaranteed.

as @CraptacularOne said, the offset doesn't matter. Use something to monitor what speed you card is getting, not the offset. I use an offset of +50 on the core and my ftw is normally aroud 1950 - 2005 (at least is AC:V.. which i've been playing)

I tested the clock on stock , in shadow of tomb raider it stays constant at 1930 mhz and goes max to 1950 sometimes.

That's pretty good as it's stock boost profile is 1755Mhz so it's auto overclocking itself almost 200Mhz beyond factory. You asking it to boost a further 115Mhz to 2065Mhz is what's causing issues. The only way you're gonna really go further is to water cool it to lower the temps. You really want to return it because it can't run beyond 2065Mhz on the stock cooler? Don't be foolish.

Thankyou for your input. On overclock i get around 2050 -2030 mhz depending on the temperature which makes me happy now :). My question is how will water cooling let me go past this number? i tested with full fan speed 100x , the temperature stays at late 60's and it still crashes if i do +121mhz or something. I think i will keep the card , i just thought i have an defective card because other people were able to go past this number.Only reason i was thinking to return it because of the msi card which i tested before that had 2x pcie power rail and performed the same with 78 euro lesser price tag. I guess i will stick with evga for now as this seems better quality build.

Lowering the temperature will allow the GPU go up another boost bin or 2 as Ampere and Turing GPUs are incredibly sensitive to temperature. Both Ampere and Turing boost in increments of 15Mhz at a time and they are often referred to a "bins". So lowering your core temp will mayber allow you to gain another 15-30Mhz without needing to increase voltage. The lower temp you can keep a component the less power you "lose" through heat as that's what your CPU is essentially doing is converting electricity to heat. The hotter something is the more voltage it will take to run at a given clock speed, this is true for CPUs as well.

omarrana123 My question is how will water cooling let me go past this number?
The boost algorithm starts at the VF curve generated by your offset (such as +100) and then downclocks from there based on temperature. A watercooled card with +100 offset will clock higher than an aircooled card with +100 offset due to this. The same OC setting could average 2140 instead of 2040, for example. It may also let you achieve higher offsets, but the direct benefit is to stay out of the higher temperature "bins". Every Core Clock/Voltage/Temperature trio has a "bin" associate with it. For example on my card if I set +100, the 1094mv voltage level has all of these bins- 2125 mhz 45C and below 2100 mhz 46-50C 2085 mhz 51-56C 2070 mhz 57-62C 2055 mhz 63-67C 2040 mhz 68-72C And that's just at 1094mv. As it moves up and down voltage due to power limits or temperature control there's over a hundred "bins" it can shift into and any one of them being unstable could cause a crash. i.e. maybe 1085/2055/55C is stable but 1062/2040/60C is not. Stability testing on air can be difficult. Every chip responds slightly differently to voltage/temperature. On water cooling you're capping the card at around 40-50C which gets you- higher clocks at the same offset fewer bins being possible (more consistency and stability) higher offsets (typically, not guaranteed)

I cannot really RMA, but I have the 14-day return policy without giving any reason.
