Different Chip Height due to 3D-Cache? R9 7950X3D Delidded 

Or just clean off all the indium solder lol

@@MlnscBoo r/woosh etc etc.

@@fVNzO I know right, I was also kind of annoyed that he used half a tube of liquid metal and still didn't wait long enough...

@@MlnscBoo Nice attempt brotherman.

@@fVNzO damn it

Haha i do this in exactly the same order!

Yes. I do this exact same thing! It's the best way to understand everything. Honestly these channels are so awesome.

lol, same thing

This is the way. Although today I watch Wendel Level1techs video, and I really appreciated his view on it.

lol same

my finger heals by itself, the chip doesn't - what? :D

​@@der8auer-en Makes sense to me haha

​@@der8auer-en True lol 😂

That depends on where you live .... here in the pay to play healthcare world of the US $700 would barely get you into the door of the emergency room ......

@@longjohn526 True, it would take some serious negligence to end up in the ER based on this situation though lol

truuue

well nobody else is lol

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.

not really an issue when you can afford to destroy them :)

I think first moving it gently and then carefully using the drill is fine.

I'm still waiting here in the US for anyone to have it. Damn thing seems to be rare or practically nonexistent.

Bro, how did you afford that deliding tool ?

@viperpit Stand corrected, I mean where to buy it :D

would mercury work too? can remove the gold too

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

@@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.

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.

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

Yes there are Through Silicon Vias in the CCD die

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

Thank you for reminding me destroying my 34 inch ultrawide by dropping my watercooling radiator on it when I put it on the desk...

@@atavusable Ah sorry mate, jeez that sucks. Can't imagine the day you had when that happened, R.I.P Ultrawide, gone but not forgotten.

@@boastyy honestly the first hours, you find yourself to be a moron, then you go "shit happens".

@@atavusable Exactly mate, was going to say "shit happens" in my earlier post. Horrible when things like that happen, just got to chalk it up to experience and not make the same mistakes next time lol.

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.

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.

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

Exactly. Even if they add the 3d cache, I doubt they would change the substrate thickness.

you can use a SOFT bristled toothbrush with ZERO force

I hope that, too. I’m curious about AM5 configurations with 4 x Micron 32 GB DDR5-4800 ECC UDIMMs. As far as I know the tests that demonstrated issues with 4 DIMMs had been done with DIMMs with SK hynix memory chips.

@@abavariannormiepleb9470 Intel platforms also have issues with 4 dimms, it's a common problem with ddr5. Probably it's time to introduce buffered memory on the desktop platforms

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.

@@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.

@@mecha207 Thanks again.

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. I like having my custom water system versus aio, other than better performance, I can modify it to fit my needs and change with the system.

A very effective way of delidding.

@@Uncle_Joseph Yes, but how safe for the dies

Right, when’s this delid took hitting the market?

seen them on several european stores!

the IHS on the 7000 cpus is one thicc boi. not really sure why amd decided that was the best way to keep thermal solution compatibility, they could have done it another way that would have kept the IHS from becoming such a large thermal mass.

Lol cooling down slower is better for the silicon

@@nemesis1588 Some diversity hire had a great idea to keep the overall thickness of cpu near the same height as AM4 so people could reuse their coolers with some additional brackets. Which is so retarded I can't even fathom how they signed off on that. As is today, you need a new bracket anyway so why not just make the cpu thinner and cooler and solve the height difference with the bracket also. Most retarded choice amd ever made.

This is pure speculation, but probably because AMD Germany didn’t provide him a sample. So he got one from someone who did get a sample, but they don’t want AMD to retaliate against that person.

@@docbrody oh right, thanks

Interesting idea, but I think you'd actually need a very high temperature and may risk desoldering the CPU dies themselves if you aren't careful.

It's a very niche item made by a German company, I'm afraid it being overseas only is probably close to inevitable

@daasaal to quote him- @der8auer-en 2 hours ago we're working on that :) will be better very soon

You can order from OCUK with insane shipping or wait. I already see overpriced direct die frames on Amazon.

We design them :) and we test them

@@der8auer-en now i understand :)))

I’m guessing 8c+cache and 4c without. That way AMD only needs to dealing with manufacturing one chiplet SKU with v-cache. We won’t know for sure until der bauer gets his hand on it though!

​@@dylanjastle all chiplets are the die. They just laser off cores, which is automated during the binning/QC process. I would imagine the bin before adding the cache, so the failure rate is low.

@@ionstorm66 Would it change any of the process to put cache on top of a fully enabled 8-core CCD vs a CCD with only 6 cores enabled? Seems like it would change something subtle to give only 6 out of 8 cores access to all the cache vs 8 cores. Maybe it changes nothing though. 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.

@@dylanjastle apparently it’s the 6/6 configuration. 7900x3d could be dog water compared to 7800x3d

@@dylanjastle Stacking v-cache on 6 cores instead of 8 should be fine because it's all shared. Even the other chiplet can access it but that's obviously not ideal. Also take a look at the base clocks. Both the 7950X3D and 7800X3D are 4.2 GHz while the 7900 is 4.4. The only reason for this I can think of would be 6 core chiplets.
