[@ScottGrammer]

I would imagine that the cpu was supposed to be more than 8 cores, but one CCD failed testing, so they just disabled it and made it a 6-core unit.

[@mintynuggets]

It's like those 3 core athlons where you could enable the fourth core in the bios

[@JE-zl6uy]

@@mintynuggets I am curious if you could turn the second die on and get 2 extra threads out of it.

[@WTFZOMG]

yeah maybe supposed to be a 12 core part, but one CCD didnt work after they packaged it so they binned it down to 7600x

[@ViXoZuDo]

@@mintynuggets yes and no... those athlons were true 4 cores with 1 disabled just to keep the SKU. The first batch of the 3 cores was impossible to unlock since those were actually damaged cpus... later on, the fail rate was too low to keep the demand, so they started to disable good cpus just to keep selling the SKU. In this case, I'm almost sure this is an actually damaged cpu and later on, I don't think they will start to sell 2ccd cpus with one disabled since it doesn't makes sense.

[@kathrynck]

I think so too. Specifically a 7900X, as it's 12 core, so half would be 6.

[@osirisgolad]

I think it is also worth considering that the packaging process can produce a defective package. It's not just the photolithography process that can produce a defective die, but the packaging process can use two perfectly functional dies and if one of them is misaligned, the electrical contact between the substrate and the die may be too poor to keep that die active. So this may have been intended to be a 7900x, but when it was tested post-packaging it was found that one of the dies wasn't up to snuff and it was salvaged as a 7600x instead.

[@fasteddy664]

Yeah that was my thought as well

[@mycosys]

Yeah that was my guess, the CCD was fine but the substrate bond failed during assembly. Was a little surprised to see it inactive actually, AMD have a history of dual CCD x600 chips.

[@halbouma6720]

Yeah, I expect failed single 8 core CCX and/or failed cores in a CCX moves them into candidates for turning into 7600s. It could also not clock high enough for 7700/7900 versions as well.

[@PainterVierax]

@@halbouma6720 AFAIK manufacturers do QC tests and binning before assembly (sometimes even before cutting the wafer into dies) so with this chiplet design it's way less probable that failed or low clocking cores are simply deactivated like it was on previous monolithic die designs. It's also more costly effective that low clocking CCX are stockpiled to be used for future skus for desktop or more probably server or mobile products (if they use the same CCX design over the whole generation) instead of being deactivated. All in all, as OP said the most probable hypothesis is a defect during the bonding process of the CCX on the interposer in a 7900x assembly line. And if it's the case this rebranded 7600x should be a golden sample (at least for the usable CCX) compared to the usual quality tolerance of this sku.

[@denkigundam]

The thoughtfulnes and transparency around the development and bundling decisions for the delidding tool are really nice to see. The thoughtfulness around re-use is awesome. I wish more companies could focus on and embrace re-use like that.

[@Exostenzaa]

He also understands that anyone who delids their CPU with his tool is going to have to buy his contact frame so more people that delid means more contact frames sold which may be the real money maker here. I agree the transparency is great but I don't think this is as much of an altruistic thought process as you think. Either way der8auer is the man and I am not trying to be negative about him and his products at all so please don't take this the wrong way. If I end up going Ryzen 7000 when the X3D chips come out I assume I will be using this tool eventually with a contact frame (assuming he updates both for the added depth of the X3D dies). Stoked that he is finally doing this for AMD now that they are LGA.

The fact that he's like "yeah, we want to make it so people can buy the delider and share it" instead of the standard business mentality of making it a bundle for maximum profit is why he's a gem to the community.

[@javaguru7141]

Yeah. It's such a breath of fresh air. I respected him before but now he has my _absolute_ respect.

[@CMDRSweeper]

To put it differently, he is working in a very niche market with this tool, and if you try to gouge when you are in the niche market, it spreads pretty quick and you are out of business with a broken reputation. Consider what else DerBauer does, he has to keep that reputation to keep his other more mainstream products like the thermal paste going strong.

[@clansome]

There's another thought that they won't cap the market as by the time "saturation" has occurred in what is a very niche market then sufficient capital has been built up to help fund the next project.

[@yuuki-yuuki]

On the other hand, a good amount of cost is from the material. It won't create much more profits by selling more in new. Lots will be given to the factory for raw material.

Great work Roman! Good idea to verify the function of the 2nd CCD with the thermal camera.

[@jurgiszalitis]

It was intended to be 7900X, 2 x 6 core CPU. If one CCD does not pass the QC, you can downbin it to 7600X and rewrite the CPU name in ID. It was done already for 5900X to 5600X and 5950X to 5800X CPUs too.

[@righteousone8454]

Well maybe don't. I ruined two cpus that way. This round I was working soooooo careful, but liquid metal tends to roll off, microscopically. Sometimes you won't see it at all. At first it was all good, then motherboard went bye bye. I ruined 2 gpus and 2 cpus. Last motherboard I destroyed forced me to buy 13900k, because finding z390 motherboard is next to impossible now. Unless you want to spend 300 bucks on motherboard. Liquid metal is a bit*h Thermal Grizzly liquid metal graveyarded GTX 1070ti, GTX 1080, i7-8700k, Z370 motherboard, Z390 motherboard. I made a final decision never to do it again. Liquid metal is too dangerous, even for a very careful person like me. You have to be very careful on tilting your pc afterwards, as liquid metal can run off, it's not worth it. I delidded 9 I9-900k just fine, but it made my motherboard die, and I was so careful. I am going to be one of the few to really say: Please don't. It reduced anywhere from 12 to 15 degrees for me, but then eventually liquid metal ran off, if you tilted pc or blew dust with dust blower/compressed canned air. So, yeah, know that it can happen, be ready to lose parts as the greatest risk.

[@RicardoRamosRetrocomputacao]

I believe both explanations are correct. The 7600X are 79xx to cover the demand, but they are also defective. The first batches always suffer from a higher level of defects. AMD is taking advantage of them for the 7600. This reminds me of the Phenon X6 times, when many Athlon or Phenon X2, X3 cpus were actually X4 versions with cores deactivated, easily "fixable" by the bios. Despite being faulty, most of them worked perfectly on vanilla (no overclocking), I had a few myself. This also happened frequently with video cards, the first versions of cards like geforce 6200 were actually defective geforce 6600, but most of them could be modded and work normally. There were cards like this on ATI too. This usually happens during launch, and for a short period of time, just the first revision and for the first few months. After a few years, the information spreads over the internet, and a race begins in the used market to find these models, and they go up in price.

Second Stage CPU Binning, likely during the BURN-IN test where on CCD gone bad during that particular testing but the other had no issues. Something you can not do with Intel yet and that lowers costs for AMD even further than just the chiplet approach and CPU cores being technically multipurpose like Ryzen, Threadripper, EPIC, etc all using the same CPU cores chiplet. It's one detail that APU's have been missing since the first ZEN series but that looks like is now being addressed. From what I can see next gen APUs will also be a full chiplet based design instead of monolithic, something I can't wait to be ready, specially when they start combining CPU/GPU/NPU etc on the "SOCs".

[@kotekzot]

It would be pretty funny if AMD decided to release "big.LITTLE" CPUs with a poorly-clocking chiplet locked to lower frequencies. Probably not worth the effort for them.

I assume you probably can't say anything definitively yet, but do you believe that delidding will be any different on Ryzen CPUs with 3D V-Cache? Maybe you've tried it on a 5800X3D?

Reminds me of decades ago where all 386 chips manufactured by Intel were supposed to be 386DX chips with the onboard maths coprocessor but the failure rate of the co-processor unit was high enough that they disabled them and packaged them as 386SX chips at a cheaper price to minimise waste and maximise profit. Then they also then marketed external maths coprocessor chips to make up the difference if you wanted. Disclaimer - this is all from memory so haven't actually googled it to see if my memory is correct 🙂 So is very possible AMD are doing the same thing here (as others have commented) where to minimise waste the "faulty" higher specced chips are having the faulty bits disabled and the chip sold as a lesser model to minimise waste.

I'm betting the 7600x is just a 7900x with a disabled failed CCD.

@@Nicholas_Steel ah and thats why the 2nd ccd stayed cold at boot up...or maybe the second ccd is just disabled compleatly...would make more sense...

[@ghostofdre]

The 5600X and 5800X had some dual CCD chips at launch, they were chips that didn't validate as their 12 and 16 core counterparts. They also had issues with ryzen master.

[@everydaysurvivalgear]

Hey mate, can you use a wing bolts or a hand bolt as the moving bolts? How much torque is needed to break the IHS free? I think the bolt head might get threaded (damaged) if people use a cheap hex bit/key (or the wrong tool for the job lol) considering it could take 20 times each side. This probably depends on the experience level of the user. Any ways great build.

[@zzonerr]

It was same with the 5600x. The ryzen master sometimes wasnt showing temps or hwinfo was showing 2 ccds.

[@MrTheta..]

For noisy times, you can use a directional mic. They work amazingly well!

[@glitchered]

props for adding some sort of fix for this weird design flaw, there. back in the day direct die was pretty common. maybe this could become a good standard again, to get the rising wattages and temperatures in check. yo :)

[@playerzero0000]

As far as the lapping tool, are you also making a new backplate or mounting bracket to preserve the required mounting pressure (seeing how the IHS will be lower after lapping)?

[@JazekFTW]

Cool video Roman!! What about a direct die contact frame for raptor lake? Theres none from thermal grizzly right?

[@afungusamungus2860]

Delidding has come so far since the old hammer and vise days, thanks for the dellidding tools

[@I1S1337]

I’m so excited for this product, I know my best friend is eagerly awaiting this for his 7950x

[@artura5526]

Perhaps it can be unlocked like cache in Duron, by repositioning the transistor or the pencil mod :) If you have naked 7900x or 7950x can you check the layout of those to see the pattern ?

[@tech-daddy]

Great stuff, thanks for developing gear for the ultra-enthusiasts among us! :D

[@Splatooooon]

reminded me of toms hardware back in the day with the cooler removal and subsequent smoking athlons as a result, whereas the P4 willamette just throttled and still managed to run

[@jumpinfool]

Been watching your videos for years. Any update on a release timeframe for the 7000 series delidding tool and direct die mount? Thank you for all your great work!

[@dabriudabriuiutubiu]

On the direct die kit, would you be willing to include a sponge mask to trap liquid metal, similar to the one used in PS5, but pre cut in the correct format? Maybe create a direct-die and liquid metal bundle? Also, do you feel that the stock "glue" on top of the caps provided by AMD is enough to protect from shorting with liquid metal? Or would still recommend to apply nail polish?

[@Cblan1224]

Can't wait to see what this process looks like on the x3d chips

[@mikeyp916]

Maybe you could fix the forcing screw into the base plate so that you could just loosen and tighten the bolt instead of going side to side, like press a bearing into the base plate and press the bolt into the ID of the bearing. Just a thought. Looks like a nice tool though, good work!

[@FakeJeep]

5:30 That was my remark on the first video... it felt like you were breaking it with that much force lol

[@RVail623]

At 12:05, the CPU-Z version being used is one revision out of date. Intel's 13th gen CPU socket 1700 mechanism appears to still have the same defects as the 12th gen mechanism, no?

[@harrybow09]

Hard anodising is awsome stuff on our motorbikes we use hard anodised aluminium sprockets instead of steel to reduce weight and they last just as good a steel ones.

[@anonamouse5917]

Great vid! For the record, how thick is that IHS?

[@pr0xZen]

The little voltage regulator chip active is probably kept awake by the USB controller. So that the USB ports can keep devices power-only devices alive or be used for charging, when the system is off. You can disable "USB always on" (and RGB always on ofc) in the UEFI/bios. Some always on RGB accents are actually powered through the same USB controller, so turning off "USB always on" turns off the RGB accents too. A quirk of USB always on, at least on older Intel boards, is that depending on how your keyboard and mouse is wired (a lot of Razer stuff does this), if you hit a key or click the mouse after powering on, the keyb/mouse RGB will come on. And never turn off, until next system shutdown.

[@lemagreengreen]

Are there any differences between the single and dual ccd chips in terms of other components on the cpu board? It's likely just a rejected/damaged higher spec part but there is a possibility that maybe the second die is just disabled to make it a cheaper part.

[@jason2jz]

Pressed like button before started even watching the video. Will there be oc/thermal testing with that delided 7600x?

[@he8535]

Your products seem really professional

[@petpan82]

great video thank you

[@newroo]

Oh lord! Now i want to see the result after using the delidtool and direct-die with 7950X using liquid metal!

[@EinSwitzer]

Chamfering polish and flux soak also substrate soak with gel

[@phlogistanjones2722]

Thank you for the interesting video. NEVER apologize for putting out a quality product.

[@-GameHacKeR-]

I really want to see a video of the amd lapping tool with tests of compatiable coolers like the nhu12a.

[@Dlo_BestLife]

Dude is a beast. Love his content

[@AvgDan]

It would be REALLY cool if you could design these to use cam levers to move the slide back and forth instead of screws!

[@RatBagDad]

While cam levers would look extremely cool I would worry that they possibly don't offer the same level of fine-tune control or the range of torque that manually turning a screw thread could. Also, I suspect it would increase the production cost leading to higher final sale price.

[@shaneeslick]

G'day Roman, 😲Well that was a surprise & the story behind the 2 Chiplets R5 would be interesting to have answered. Also some information on Yield would be great, TSMC Quality seems to be very high with minimal Failed Cores in Chiplets so I am guessing a R3 *300X will not be possible again & any Future R3 will be based on APUs.
