Review: ZOTAC GeForce RTX 3080 Trinity
In this review, we benchmark the GeForce RTX 3080 from ZOTAC, a very nice customized yet reference clocked product. It attempts to offer close to reference performance, good acoustics as well as a friendly design. All priced rationally as well, we hope.

Just a opinion, feel free to disagree :>
If NVIDIA is binning the chips and keep the best batches for themselves then the issue with CTD that
affected mostly AIB cards is really NVIDIAs own fault and basicly shooting themselves in the foot because
they had to adjust driver afterwards so it affected all cards even their own and not just AIB cards.
They knew in advance that most AIBs would create overclocked versions of the RTX 3080 GPUs.
So even if NVIDIA FE RTX3080 GPUs passed all NVIDIAs own tests, a lot AIBs would be close to failing
because their so close to the vcore clock limit already and really no wonder some would fail going
above 2.0GHz since the tests AIBs could do was limited and NVIDIA could test anything they wanted.
Some AIBs still created nice normal and overclock versions I think, but it was really a gamble from
NVIDIA that did not go well. They should have known better.
I will still buy a 3090 but most likely a one of the normal versions and not factory overclocked ones :>
I rather overclock it myself a bit or not at all than bumping into issues down the road because a driver
and/or game/rendering suddenly pushes the GPU to much.
Digging a little deeper, we can see a minor voltage differential, likely this is related due to ASIC quality; NVIDIA might be binning the chips and likely keep the best batches for themselves. The differences are a negative 1 to 2% at best, though, so that remains marginal but measurable.

I recommend to undervolt, overclock and add custom fan profile/curve on these cards all in the same time. Best way to get best performance, noise levels down and temps down while keeping it stable and not throttling or anything like that.

We fired off several tweaking scenarios at the card; it's difficult to tweak, and with the recent CTD issues in mind, we need to wonder, would you like to be in that 2.0+ GHz range? Even an automated curve based overclock would not be stable. Much like we have seen with other cards, the tweaks on the memory frequency will run fine, but the performance was lower. New safety protection is active in memory. A +1000 MHz would result in poor performance but no stability issues. Ergo +500 max currently is what I'd recommend on the RTX 3080 cards (but this will also differ per caird and brand). Of course, increase the power limiter to the max, so your GPU gets more energy budget, and then the GPU clock can be increased anywhere from +40 to +100 MHz, but here again, that will vary per board, brand and card. So, in the end, I expect 20~21 Gbps on the memory subsystem (effective), and with a +75 Core frequency and added power, you should see your card hovering at a 2 GHz range (which is pretty awesome).
This one is the interesting part regarding the +2.0GHz...issue....
