My custom M4800

[MELOCODI]

I use PTM 7950 + Upsiren UTP-8 putty on CPU+GPU dies and VRM+VRAM

Didn't have any results yet, but from what I see - this GPU needs a VBIOS with less max TDP, this goes into a scary territory + some scary coil whine. This is under FurMark 2 VK stress test ≈ 1 minute.

Coil whine = high FPS. Happens on every cards I own.

 

What FPS did you get for average?

 

Isn't the maximum throttle 87C for the core? That's good! Hotspot throttle is 105C I believe. Maybe -10C with a two heatpipes design. Standard heatpipes, not the "big flat" one.

Here is the best picture of the internals I took a while back, maybe that will help, I tried to play around with some heatsink parts to kinda check the fitment, but couldn't figure out how to jam in another heatpipe on the GPU, tolerances are pretty tight... maybe cutting the palmrest plastic is the way? Don't wanna ruin the rigidity

Thank you. Is the Ethernet port in the same height as the GPU heatpipe?

 

Can you overclock to 4GHz all cores using NVRAM edits + sleep bug to unlock the TDP?

I'll check the height. 

 

About an overclock - not sure, I am running (1 core - 4 core ratios) : 43, 42, 40, 39

That sounds like an overclock to me. Chip can handle 43, 41, 41, 40? Single-thread in CPU-Z, it's 420?

Looks like it

We can run a heatpipe on the ethernet without trimming it, okay.

There's no place on the copper grid to solder another copper tube - where are you planning to vent the heat, then?
