Please dont tell my that you paid an arm and a leg for that 3080

 

[nguyen]

Tried mining Ethash for 10 mins, getting 100MH/s and max memory Junction temp is 90C and 86C with a fan blowing over the backplate. 3090 undervolted to 1740mhz/750mV (mem +100mhz so 19.7Gb/s) and using an avg of 290W during mining.

model is Asus TUF 3090 with Bitspower full covered waterblock

 

[toilet pepper]

Strix had a full cover block and a back plate that was another $40 on top of the block lol My mate was gutted as it's not helped a thing and I believe that these heatsinks I've ordered as well won't help much if at all either.... We'll see when I get them through

The 3090 have actual chips at the back and the GDDR6X needs actual cooling. I'm thinking a simple backplate would not cut it. They need actual cooling and I think EK has some sort of quantum cooling thing where the backplate is kinda watercooled as well.

With how hot these GDDR6X gets, traditional cooling for graphics card would not cut it. They should have separate cooling from the gpu core. These things soak most of the heat capacity of any heatsink. The 3090 should have had HBM or lesser chips to ease that problem with cooling at the back.

I get 105-110MH at 1600/0.7v, 250W

1.5mm pads arrived today, looking forward to doing both sides later

memory speed? that's a bloody good hash rate, here I was thinking ~90 was pretty good but even with a 3080 I could get 97 or so it seems, just need to find the magic settings.

I only ran the miner without setting up a wallet or finding the closest pool so hashrate could have been better I guess .

 

[wolf]

Anyone seen this yet too? Mining GPU's and Nvidia gimping Drivers for the 3060's mining ability.. lets see how long that all lasts!

Tell your mate to put the old Strix cooler on top of the backplate? could have drop the temp by a few degree .
The TUF model have separate VRAM heatsink and that could have looked more elegant.

 

[Mussels]

Okay: looks like my 3090 needs 1mm 1.5mm and 2mm

I kept most stock 2mm, so strangely i've seen almost no change to the junction temp - 98C with my ghetto fan mod on top, 102C without

That said, GPU is now 57C while mining so hell yeah for the new thermal paste

Update: ugh its hell getting the right sized thermal pads, one? of my chips hits thermal throttle so i gotta rip it apart, guess, and try again with differing thicknesses

 

[purecain]

Its the cable, I reconnected it and now the sleep problem is gone. How about that??? Id be happy if I hadn't just been criminalised by the next door neighbour. Meh!!
@wolf Those mining GPU's will be worthless as soon as the mining ends.

Well I tried to warn you replacing thermal pads are fruitless endeavor , you would have better thermal running the fans at higher speed anyways.

I'm seeing <60C while gaming so there was some big upsides with replacing the non VRAM pads

I caved and ordered gelid 3mm ones so at nuts prices, so after wasting all this money i'll finally have it working as intended.

This is what i will be buying for the GPU: GPU Block

Yes, and the 3080 1.5mm 2mm

You can't use manual from a specific waterblock for thermal pad thickness reference because different heatsink/waterblock have different design, some have taller protruding surfaces that requires thinner thermal pads.

From that manual alone I suspect the EKWB only focus on GPU thermal and not the rest of the PCB, my Bitspower WB has thermal pads placements for all the capacitors and inductors (which produce some heat too)

And the Bitspower WB use 4 different pad thickness (0.5, 1, 2 and 2.5mm).

 

[thesmokingman]

Wait what... you guys were getting your pad thickness' from different products as a referance? That's the wrong way to do it! Measure the relative thickness of your own stocks pads then add in variance. I'd also add that stock gpu pads usually have a crapton of clearance because they have big variations in their manufacturing. Waterblocks on the other hand have much tighter clearances as a result of their tighter tolerances, especially in the case of Aqua.

honestly i f*cked up and removed some of mine before measuring, because at an eyeball glance they all seemed the same (then i found out that 2mm and 2.25mm exist)

wait what, 2.25mm thermal pad exist ?

I dunno... about that thickness, but if it were me I would get the brown Fujipoly pad slightly thicker and be done with it. The Fujis will squish down a bit filling the variance that you find yourself in. Note once the Fujis squish down they eventually break apart when removed, ie. they can only be reused once or twice if yer lucky.

i got gelid extremes, so now i've got 1.0, 1.5 and 3mm - i'll make this combination work, damnit

wait what, 2.25mm thermal pad exist ?

came up in an image earlier in the thread, theres a bunch of weird sizes that exist

i just need larger than my 1.5mm, cant find 2mm for sale - so 3mm and squishing it is

My mistake not to point that i was talking about EKWB Blocks.

From that manual alone I suspect the EKWB only focus on GPU thermal and not the rest of the PCB, my Bitspower WB has thermal pads placements for all the capacitors and inductors (which produce some heat too)

The Vector water block directly cools the GPU, VRAM, and the VRM (voltage regulation module) as a cooling liquid is channeled right over these critical areas. The water block is in contact with the power stages of the VRM.

then i found out that 2mm and 2.25mm exist)

I bought some 2.25mm years ago, i think it was for my Evga 1080 Classified or 1080ti FTW3

I thought I'd update everyone with a few developments

The MSI card I have, the temps are fairly steady under mining, about 90 to 98C at most depending on what I'm doing with the card (overclocking etc.) and I've got some more heatsinks coming today and some thin thermal pads so I'm hoping I can put the pads and the heatsinks over where the heatpipes are on the back plate to help with disapating the heat from the RAM. I highly doubt it will do anything much at all but for a few quid of effort and such, it's worth a try

And as for my Strix card, that was put under water and the temps, surprise surprise, are no different under mining, even with gaming as well, they are the same as the air cooler... So long and short, probably don't bother with a block...

Well guys just to confirm the status of the extra pads and heatsinks, whilst it's removing the heat and doing what I had hoped it would do, the temps are the same. There's no drop in them at all. So I'm guessing the probe for the temp is either reading wrong, in a place that can't be cooled better or any other reason, but it's not cooling down any better at all.

The Strix with the water block and back plate are working but temps are still in the higher side than we'd like 96C I believe is the maximum my mate has seen but otherwise, it's all a bit of a muchness. I believe EK are releasing a new backplate so I believe my mate is getting that to see if the temps go lower, otherwise I think it'll just be a case of suck it and see...

expensive thermal pads and backplate are not going help much since the surface of the memory modules have horrible heat transfer property, maybe someone should try sanding down memory modules .

Lapping it'll work!! Maybe I need to get an iFixit kit, that fixes everything, right??

 

[purecain]

Fixed the sleep issue with a new cable... I kept second guessing myself, just installed a new cable and put the pc to sleep and it woke back up with no corruption issues at all. Card is working perfectly.

 

[Mussels]

New thermal pads in, they were too thick at first so i gave em the old FUCK YOU SQUISH and then they fit just fiiiine

It's like these memory chips just keep ramping themselves up and never give up on their goal of running at 100C at all times under load
