I watched this item for the last 6 days and today finally see it bidded til the last minute, yet i let it passed.



Still better price than our very own scalpers in carousell, shopee and lalada.

nicehash if you dont have 2.7gh/s or you want to have small rigs running on nicehash so you can later pay for hashpower for your sparkpool. sometimes its profitable to buy hash power there.

hi bro, u got download the GPUZ to check your 3090 memory temperature? i owned a R12 3080 and without opening it out to add thermal paste is impossible to mining it at temperature below 110 for the memory alone. The case design and the fan design make the card heat up so fast.... mining eth for 15min will have your card over 110 and have the card automatic throttle. Only after adding thermal paste to the DDR Ram directly only able to bring it below 100.

As for 3090 i owned a Zotac 3090, the heat for the card mainly comes from the back DDR rom as it does not have cooling fan on it, even with added and upgraded thermal pad plus thermal paste the thing can run up till 106 degree, only solution is either u got waterblock cooling or u add fans to the back of the 3090. That alone will bring the temperature down till 90 something.

So as now you combine r12 with 3090 (dell oem card really have bad cooling design) it will be very hot and i can imagine it will be pretty difficult to bring down the temp of the back.

it will be a complicated design with fins built into your heater tank and high chances of leak and very difficult for maintenance. if algae happens you are in trouble. it can be done but remember thermal equilibrium, i dont like the idea of water cool cards running at 55C and above. we design water to be 120C so whenever you switch on the tap can always enjoy 38C good warm temperature for bath tub or pure enjoyment. sometimes higher temp for the water vapor effect.

you need one pipe design for in and out for connection to your water heater tank, preferably use thicker copper than usual. secondly from your wall to your gpu racks can use quick release. depending on volume and height difference you might need a booster pump that can handle coolant and not leak. and hopefully your heat sink in the tank will not corrode or covered with any other dirt that comes with incoming water.

last but not least the temperature once reach 50C in your water heater tank your  gpu will be running at 60C or more, i havent put into equations to calculate but roughly there. dont forget your walls will be warm all the time also.

R12 mobo is not greatly exceptional as any x570 can do same or better especially mid to high end boards.
Cross fire doesnt need any adapter for all boards, nvlink is require if only you wanted to run 3090+3090 in a very stable manner for example AI, rendering etc. dual sli can be done w/o nvlink but performance isnt great.

and the amount of gpu is limited by your cpu on windows os, linux is the way to go if you want to build more than 8 gpu. intel processors can handle less bus lanes compared to ryzen, even your mobo has a lot of lanes, there is only so little you can use them in a stable manner.

3090 is space efficient compared to price and performance ratio. depends on your current size and priority. my 3090 running at 40 to 45% efficiency compared to 3080 50%, 3070 50 to 56%, 3060ti 49 to 55%.

if you do not plant to run rtx 30 series on pcie 1x is doable, else your system will be unstable on windows os.

if you have space, fill up the gap and make your pcb and backplate contact while adding small fins usually for robotics on your back plate, it works. of course make better ventilation of the case or just run the pc wil all panels open, bare case would be another option.

Now i baru know aurora got this kind of issue, thx for sharing, no, i dun have the answer u desired, since my motherboard can detect 3 gpu without issue (all nvdia card). just wait other sifu tell u the answer 
This is ur rig? the monitor reflection show a girly liked person holding phone, with naked muscle man poster behind the wall.  
anyway, nice hashrate and temperature.

so most likely dell disabled those slot at hardware level or bios. Recently dell aurora gaming series were banned in some states of united state due to some stupid energy regulation.
So u should write to them regarding this disable slot bs if u haven't already.

I don't have any dell aurora pc 
Just hope that they will provide you an easy solution to re-enable that additional slot, good luck
