How about 3D printing a cover to protect the rest of the chip when you're scraping away the indium? Could also be used to hold it level, helping prevent gouging. Added bonus of stopping the liquid metal from spilling over from that lake!

[@mme725]

Oh that's a good idea.

You could just put the CPU in his direct die frame. The caps are lower than the die, so just use a blade that's wider than the frame.

Absolutely love your content Roman! Dont forget to always include your beautiful and helpful family members, it is actually half the reason why Im watching your videos😸

[@1234567890CAB]

You should use pure gallium instead of liquid metal when cleaning up indium TIM. Just rubbing gallium and indium together will cause them to alloy together and form an alloy that is liquid at room temperature. Liquid metal is already alloyed and has other elements in it besides just indium and gallium to make it cheaper. You can also easily make the gallium liquid with just a bit of heat and still handle it in liquid form. The result you'll get can also be reused in place of liquid metal.

[@jebdiankerman5029]

would mercury work too? can remove the gold too

[@Demopans5990]

@@jebdiankerman5029 Nope. Also, Hg is kinda toxic and hard to handle in general

[@spankeyfish]

@@jebdiankerman5029 You probably don't want to take the gold off anyway, assuming it's actually gold. That coating will be to help the solder stick so it might also be beneficial for liquid metal too.

[@1234567890CAB]

The thing with mercury is it forms an amalgam or amalgamation when it alloys with other metals. What that means is it "soaks up" the other metals and then begins crystallizing with the metal to form a rigid or semi rigid form. That's why it was used for teeth fillings. The liquid mercury could fill all of the crevices of the tooth, then gold is added until the filling hardens up. The filling then continues to harden as the crystal structures form.

[@seanmurray170]

Sounds great, but where would an enthusiast layperson buy gallium and know what they're getting?

Hi Der8bauer, Are the EK Quantum Velocity2 AM5 Blocks and Pump/Block combos (With 4.2DDC Pumps) compatible with a delidded 7000 series CPU and AM5 direct die frame? Unfortunately I cannot find anything online or on EK's website. Thank you! Big fan of the channel!

[@cj0147]

You Are Awesome!!!!!!!!🤟

[@toomanyrobertos]

I would like to see an X-ray of this CPU

[@Vatharian]

Why you never use heat to remove the solder tim from the CPU after delid? Actually - why you don't heat up the CPU for the delid itself?

[@abavariannormiepleb9470]

Question about AM5’s heat load, I don’t have one yet since I was waiting for the 7950X3D: Can you simulate the cooling requirements by having a 5950X with PPT/EDC/TDC limits removed that this way takes up to 250 W under full load?

[@StevenMussels]

you can simulate wattage but not temperatures since how the coolers mount and heat density varies between every CPU design

[@P4NCH1]

AMD right now: We forgot about the sample for der8auer! *grabs head with both hands* :P

[@IntenseGrid]

If someone is going to direct die cooling, is it necessary to get off the indium? Wouldn't it be the same to just add enough liquid metal to fully liquefy the indium, take off any excess, apply to the water block and then mount it? For this video it was necessary to get rid of all of the indium so that accurate measurements can be taken so it had to be fully cleaned. Normally though, I am thinking this step should be skipped. What say you?

[@ThmsDouglas]

So, would it be worth it to delid a 7800x3d just to replace the tim with a good liquid metal? I'm talking about not doing direct to die just replacing the tim. Wait my brain was elsewhere on that question, how am I going to reattach the heatsink ? 😅

[@PBehr]

When can we expect the delidder and direct die frame for AM5 sir?

[@muskwasis1705]

[@yeshwantkethineni3694]

[@Daxelman]

[@exithe]

AKA "I would rather cut myself than my 7950X3D" eheheh

[@andrewb6]

Hmmm. Maybe they started making the cache die the exact same dimensions as the CCD's. Perhaps they also spread out the SRAM cells, and put in lots of thermal via on the die, to assist with removing the heat. Know anyone who would want to desolder their die from the substrate, and each other?

[@shadowarez1337]

If you had some form of metal polish like Fitz from rockit cool it shines up the die very nicely. Used when I delidded a 12900ks looked exactly like your results here till I put some polish on the die then it was mirror Finnish.

[@joescalon541]

Wonder if this will help with the Ghz on the v cache CCD. So far from a few tests I have seen it doesn’t even hit 5ghz. Wonder if 7900x3D is two v cache CCDs or 8+4?

[@JJFX-]

It's definitely not 2 v-cache CCDs. The question is whether it's 6vc+6 or 8vc+4 which still seems unconfirmed. The fact it has a 200 MHz higher baseclock than both the 7950X3D and 7800X3D makes me suspect it'll be 6+6. That'll be strange but you may be able to squeeze out higher clocks, similar to why to the 7900X can occasionally beat the 7950X. I think it'll be hard to justify but we'll see. If it is, it makes even more sense why the 7800X3D was delayed. 6 v-cache cores will fit nicely below the 7950X3D but an 8 v-cache 7800X3D could make it especially silly. The one advantage of the 7900 (aside from 12 cores obviously) is that it can utilize full memory bandwidth with 2 CCDs vs the 1 CCD 7800. Plus a 6 core v-cache chiplet basically guarantees there's potential for a 7600X3D to release around summer. If entry level board prices improve by then, it could get very interesting.

[@s1n1stersixsgaming8]

6vc+6 the extra clocks is from less heat produced from 2 less cores per ccd, why the 7800x3d has the same clocks as the 3dvc chip on 7950x3d

[@mecha207]

If I recall correctly from his other video, the delidded cpu is lower in height than the mount for the heat sink thus will need another special water cooler block and a special mount on the motherboard.

[@ashleyperez-rd1wr]

@@mecha207 Hey, thanks! So at the moment, there's no point in delidding, as it won't be usable unless we do a complicated custom job? Or is there a way to do this that isn't too difficult?

@@ashleyperez-rd1wr No, there is no point unless you are chasing lower temperatures and are over clocking and have the supporting hardware. Honestly, even custom watercooling is pretty expensive but anyways that is my opinion on that matter.

Don't need a complicated custom waterblock, just one that isn't oversized so it can sit lower. The only custom thing is shorter screws mainly. Depends on how your mount works.

[@edplat2367]

I thought the 3d vcache models didn't allow for voltage adjustments etc. This is interesting content but would we see any real world benefit from this?

[@pf100andahalf]

You can adjust the voltage lower on any x3d cpu as long as the motherboard allows it (I can do it right now with my x570 msi motherboard with a 5800x3d), but if you adjust the voltage higher either with a modded bios or an external voltage regulator, the cpu will detect it and lock itself to base clock speed which in the case of the 7950x3d would be 4.2ghz. The benefit to delidding an x3d would be to increase clock speed because of lowered temperature. How much that would matter on 7000x3d's I haven't heard yet. I know in the case of my 5800x3d (that's not delidded and never goes over 80c) it will run at full clock speed under an all core workload so there would be no advantage to delid my 5800x3d, at least in my case. We'll all have to wait and see if delidding x3d's makes any difference in performance.

Previously they did two 6-core CCD's on the 5900x and 7900x skus, so it would be a change to go to a fully enabled 8c and a basically half-enabled 4c. I'm really curious to see how they do it.
