GPU Necromancy: EVGA GTX 1080 FTW Vcore VRM replacemed with Galax HOF-power

[@leflavius_nl5370]

Ah yes the E-power card, it's like a mechanical ventilator and dialysis machine for gpu's.

[@marcogenovesi8570]

it's a full-body replacement, as it provides also food/power

[@piecaruso97]

It's more like an hearth-lungs machine to be honest

G'day Buildzoid, A long time ago, in a GPU Market Far, Far Away... Episode I: The (Exploding) PCB Menace Episode IV: A New (E-Power) Hope Episode V: Buildzoid Strikes Back Episode VI: Return of the GTX1080 Episode VII: The (LN2) Force Awakens Everyone who takes time to read please feel free to join in with more Episodes or even rename these ones😁

Look who finally got a JBC, good for you and us.

[@christopherjackson2157]

Yea def you get much better results with better tools. Impressive work

Liberally a microscope, blacklight, hobby knife, and uv solder mask will clear any pcb short, now it is very time consuming but it will work.

Buildzoid doing the right thing in October: GPU necromancy!

[@ChrispyNut]

That cooler's a slightly beefed up version of the two ThermalRight's I have (GT03s something, something IIRC), mine only have 6 heatpipes, but they were pretty good. However, I'd like to thank BZ for mentioning the Raijintek Morpheus II in a video sometime ago. I picked one up a few days ago for my R9 290X and it's great, finally have silenced the card at idle and quiet under full load (until I can afford a couple more Noctura fans so it'll be very quiet under full load). After-market GPU coolers are too rare these days!

[@mikegaming4924]

Lol that as daily driver. I have EVGA GTX 1070 FTW as a project that has a hole like that in Vcore VRM...

[@ActuallyHardcoreOverclocking]

once I'm done benching it I want to make it "dailiable".

[@tanishqbhaiji103]

How does, having a jumper to the core affect the Control loop of the controller. In my experience messing around MPS voltage regulators which have multiple 100s of KHz or even MHz switching frequency the control loop is greatly accepted by the power plane impedance, Out capacitance and Minimum load ratio. Which JBC did you get and which station did you use before? Was it a direct drive one?

[@ActuallyHardcoreOverclocking]

IDK how the control loop is affected all I go by is the voltage measurements from the oscilloscope. The power bridge did introduce some kind of weirdness to the Vcore at low loads but at full load it just shifted the whole waveform up. RMS went from 1.04V to 1.07V and the minimums and maximus increased by the same amount so the peak to peak didn't change. For that matter even the low load peak to peak stayed the same the waveform just looks a little different. As for the JBC I got a JBC CD-2BF with a T245 handpiece. Before I'd use a 150W ERSA soldering iron that's really more meant for soldering copper pipe than it is for electronics.

[@OPTERON_PRIME]

Perfect content for my lunch XD

[@jacksontint]

Could you desolder components from the 1080's vrm to help the e-power lay more flat? Don't need those onboard 8 pin pcies anymore.

[@CocoaEm]

Well yes, but thats effort

[@RicardoPenders]

Holy 💩, this is the first real Frankenstein card that I've ever seen, 😲🤣🤣🤣

[@run4restrun259]

Oh, what a ... )) For new VRM you must take Vcore from pin on old VRM controller, it's call like Vgpu_sense, and put to same pin on new VRM controller. This line goes direct from GPU crystal, so it will minimize voltage droop. And there same pin for GPU_GND. So, with this you don't need so much wire :)

[@UnrealVideoDuke]

Why not look for a manufacturer that will make you a custom bare PCI-E X16 card to do this with?

[@tanishqbhaiji103]

And you don’t even have the the data lines from the core connected to the Controller, how does that work out?

[@ActuallyHardcoreOverclocking]

Running forward voltage sense lines is only necessary if you want the VRM to compensate for the voltage loss between the core and the power board. Since I'm only losing around 20mv right now I see no reason to bother. When on LN2 I'm pretty sure at 1.5V on the E-power I'll still be getting well over 1.4V at the core. As for the core talking to the VRM. Nvidia GPUs have basically braindead power delivery. The core only ever sends voltage requests. The core doesn't actually ever get any data or confirmations back from the VRM.

[@tanishqbhaiji103]

@@ActuallyHardcoreOverclocking thanks for the replies.

[@Goldenhordemilo]

i look forward to seeing what it can do on LN2

[@larsjrgensen5975]

Can I mount input capacitors on the end of the 8 pin PSU power cables, to help with GPU input capacity? I am not brave enough to solder on a 1000€ card, but is it too far away to make a difference?

[@ActuallyHardcoreOverclocking]

you can but IDK how effective it will be since the caps will be behind the input filtering inductors.

[@Us3rN4m32]

Hey buildzoid, Would a bridge mod be worth doing on a shunt modded 3080 ti FTW3?

Buildzoid, just got a 3070 and installed it on a system running windows 11 (not sure if that's relevant) and when I put it in the fastest two PCIe slots it doesn't display. When I put it in the 3rd PCIe slot it displays but obviously the bandwidth is awful. Please help if you see this

[@ActuallyHardcoreOverclocking]

does the card work in windows 10?

[@jacobs9391]

@@ActuallyHardcoreOverclocking Have not gotten the chance to try that yet, I'll be home in a few hours is that the first thing you'd try is revert to Windows 10?

[@jacobs9391]

@@abijeetrs6522 I tried to link a Reddit post about it, but no I haven't tried that, I'll do that next. I may stick the 1060 back in just to make sure the slots themselves didn't fail, and then if all is good reset default bios as you suggested

[@shaneeslick]

G'day Jacob, that is sad to hear, Just wondering if you used DDU to Fully Uninstall the GTX1060 & then install the GTX3070, If you did then all I got for help is try 'Clear CMOS', or with the GPU in the working slot enter BIOS to 'Restore Default/Load Optimised Defaults', I hope you get it fixed as going from a 1060 to a 3070 is going to be a great experience

[@Angle-ofAttack]

Those copper braids are tiny! We use larger CSA versions of them around concentric cables to carry the neutral/earth

[@KillaBitz]

I'm sure your trying to relate but..... There is over 4000a of capability on that earth bridge and your calling it tiny. that's 4kw in this use case....... tiny = flexible and easy to solder. It's not industrial equipment, it's a GPU that runs on 1v, getting cable installed with a forklift truck wouldn't be helpful.

[@Angle-ofAttack]

@@KillaBitz it has 40A current rating not 4000A also the stuff we usually use is 35/50mm CSA no forklift required

How much would it take to pull some GPU necromancy on my zotac 1080ti. Like I might be able to pay 150£ up front. maybe 150£ later to do some cool stuff?

@buildzoid i really need one of those pcb power reset board you have on that motherboard. where can i get one? all i see are the ones without a board. they have long wires hooked up to a switch. i like the little board design that plugs right in.

I got it when I was at gigabyte. AFAIK it's an inhouse thing they just have for use in the labs.

Hi, Buildzoid. Could you share the link for this tinned copper braid?

www.wires.co.uk/acatalog/tinned_copper_braid.html

[@Angle-ofAttack]

@@ActuallyHardcoreOverclocking You might like tri-rated cable, it's also braided but it's round and has a much higher rating per CSA. Your 15mm tinned braid is rated for 30A, whereas 16mm Tri rated is rated for 100A @70°c

[@Angle-ofAttack]

If you're just looking for 30A the 2.5mm Tri rated is only 3.7mm in diameter which includes the insulation

[@ActuallyHardcoreOverclocking]

@@Angle-ofAttack I like the fact that this stuff is flat. If it wasn't flat it would be way harder to make some of the connections.
