 Okay, I've got my dual socket motherboard and I'm sure you guys have all gone through this at some point in the past where you're like building a new system and like the first part arrives and you're like, oh wow, this is so cool to look at because I have nothing else that goes with it. But then, okay, it got real and two of my eBay CPUs arrived. Theoretically, these are 28 core 8176s or whatever they are, something along those lines. I got those, then I got these. Yeah, these. These are 32 gig modules. These modules have more RAM than what I would consider to be a high-end gaming system in one module. And I was like, no way. Now I can test it. Thanks to Audible for sponsoring this video. Experience the world's largest library of audiobooks today with Audible. And stay tuned later on in this video for a special offer. I wasn't sure if either of them would be real or working, so I actually ordered two sets of what claimed to be 28 core CPUs on eBay. And look at this. It's even marked on the spreaders. This is a P8136 that the seller says is a 28 core. But then I was like, hey, can you send me a CPU-Z screenshot? And they're like, sorry, I can't. And I was like, well, can you double check with someone that it's 28 core? They're like, I can't. So let's hold on. First, let's double check this. So absolutely nothing. Intel Xeon 8136. You can see I've Googled it before. But other than an eBay listing. Oh, oh, and there's a thread discussing that eBay listing and other people saying that this is really sketch. So this takes up a lot more space on the bench than most motherboards. Okay, step number one. Does this fit? Yeah, cool. If it turns on, I'm going to be turned on. Okay, so we've got dedicated 8 pins. Okay, dedicated 8 pins for each CPU. That fresh eBay smell, that thermal compound all over it. Oh, that's good stuff. Okay. So here's problem number. I've lost track, but this is a problem. The LGA3647 socket has no CPU retention arm. The way it's meant to be held in is by the cooling solution. But almost nobody is supporting this socket because this is an enterprise Xeon socket. Intel's workstation chips are actually using LGA 2066, but with a different chipset. So Asus went off the rails with this thing, and there's like no coolers to support it. And it's got this bizarro land mounting system here with like threaded stuff here and here. And then these posts that are different size here. So I'm hoping to just kind of wing it by literally holding the CPU in place. We're like the unknown side, the random side. No one knows what the hell's going on side, including the seller. If no one knows, how did you put 28 core in the listing? You're the only people on earth with this CPU as far as I can tell. Where did these come from? Where did they go? Where did they come from? Cotton Eye Joe. Oh, this is really dumb what I'm doing right now. Okay. Wait. Okay. This is bad. CPU just lifted up. Okay, I got it. Jake, I may need your hands at some point here. Oh my god, why are you doing it like this? Okay, what do you think? Is it going to boot? Maybe. Yeah, I'm going with a definite maybe on this one too. Here we go. Oh, wow, that was A whole lot of nothing. Pretty anticlimactic. Oh boy. Now most dual socket boards. Oh, Okay, postcode 00. That's not generally a good sign. Let's think. Do you want to try the other one of these first or do you want to try the other chips? I think you should try two. I mean, that's even more jank than I was kind of hoping to get but Oh, yeah, this is titanium. I think. Holy crap. Here we go. Oh, that weren't a good sign. Wow, crap. Okay. Well, hold on a second. There could still be something else. Let's try the other chips. Okay, there's some action. They're warming up this time. So that's going to limit how long I can hold these in. Okay, go ahead and hit the power. My thumb's burning. Okay, it's time to consult the manual. So it occurs to me, we have actually seen this socket before in our Xeon 5 video. This is that bizarro cooler that it used. So this gives us a few more exciting options. I don't actually know if this board is Xeon 5 compatible, but it's the same socket. So maybe we could try this chip to see if it fires up. Then we could try this cooler on one socket to see if maybe it is a mounting pressure issue. Still got options. Oh, and of course it's Torx. Okay, this looks like it may not actually be quite the same because there's like a thing here. And what? What is this mounting system? Oh, this is a narrow ILM. This is a square ILM. Crap. So we're going for hopefully enough mounting pressure. Whoa, whoa, whoa, whoa. Hello. Hello. Okay, that's fine. That's fine. We've got a postcode this time though. That's a better sign. And also, this is less likely to be CPU one anyway. So I'm going to put it back where it was. Okay, one long, two short. Great. Reserved for future AMI codes. Perfect. Brilliant. Okay, let's try a different chip. Let's try the other one. Okay. Come on. AF. Well, it could be good as f**k, like lead as f**k. Okay, it's completely different, which is maybe good and maybe bad. Why? Okay, so the manual says one long beep and two short means no memory detected. So we put those CPUs back in and we're trying the higher mounting pressure on them. Okay. Okay, so kill it. Okay. So let's just put some more memory in. Because one of the classic symptoms of a bad mount in the socket is that some of your DIMM slots won't work properly. So, I mean, this is, if nothing else, a bad mounting system. Okay, so the working theory right now is that it's probably a mounting pressure issue. So, last attempt before I just patiently wait for a cooler. I need to get up higher so I can put more weight on it. Oh, wow. That is terrifying. Why did it just turn on? I just put more pressure on the CPUs and the system turned on. Do you want to turn it off for now? Okay. I'm going to put more pressure on. Okay, let's try the other ones. Okay, that center down there, center down there. Okay. More weight. And I'm good. Have you tried clearing the CMOS? No, actually. Yeah. It's the same as before. Okay. It's been like another week, two weeks. I don't know. The point is today was basically Christmas because first, and yes, it's only the 19th, but it's still Christmas because first, check this out. So, I've got those engineering sample processors that I ordered when I thought that Intel wasn't going to work with us on this. But today, I also got... Oh, oh, oh, look at this. Oh, it's beautiful. So, these are Intel confidentials. I don't remember what skew these are, but they're 3.2 gigahertz base, so they're a lower core count. And these ones, Xeon Platinum 8180s. These are the top of the line. But it was the kind of I ordered new computer hardware Christmas where... Get a little cricket there. Where I didn't have a piece that I needed still. But then today again, they arrived. These are Intel thermal solution box coolers for the Xeon processor scalable family. This is the one active cooler that I could find on the market for the square ILM socket. I finally have everything. We're still going to try that eBay processor first. I really want to know if I got ripped off. With how hard this is clamping down, honestly, I do not feel like I wasn't putting enough force on it before. I really don't think that was the problem. So theoretically, if these work, then I have two sets of 28 core processors. If they don't, then I still have one because sometimes it's nice to be Linus Tech Tips. And have Intel send stuff over to you sometimes. Do you get sweaty when you're working on expensive stuff? Yeah, me too. I need a graphics card. Wow. So the 8136 doesn't work. Now I'm wondering if maybe there's a problem with our board at this point. So let's try a retail chip. So each of these Xeon 8180s is, I think, eight or ten grand. Something like that, retail. No pressure, though, you know. I mean, don't they know that people drop things? OK, so this is with a very probably known good chip this time. If this doesn't boot up, then I have my doubts about something. Oh, did that just change? Yeah, it did. Does it just have a really, really long post? How interesting would that be? What if it has some kind of first boot process where it has to go through some kind of detection thing before it can then boot up properly the next time and it's really long? OK, we are attempting a USB BIOS flashback with their crash free BIOS thing. We have a problem, though, and that's that if you look at the BIOS revisions here, the one with the higher revision number is dated earlier than the one with the lower one. So let's pull that out and try again. I wouldn't have thought we could make it worse, but we did. Zero zero postcode. This is 2666 megahertz, 32 gig sticks. I wonder if it's been a RAM compatibility thing this whole time because I've never actually tried different RAM. OK, new plan. We're going to try the 32 gig sticks from seven gamers, one CPU instead. So these are older, slower memory modules. These guys are 2133 instead of 2400 megahertz, which is like bleeding edge for servers right now. Maybe we'll see better compatibility if we try something a little bit older. 97, B2, 98, 99. No, no, no. It was just RAM compatibility. No. Oh, come on. No, it's up. Oh, sick. Overclocking. Yeah. Yeah, I want to overclock. I mean, not now. I want to get it like working reliably first. But how you just keep them in. Look at this. Five billion volts. No, do I just type in auto? Wow, that is jank. Oh, there they are. 56 cores. It's booted up. OK, it still won't boot into Windows. Just a little more troubleshooting. It's finally booted. So these are the retail chips. And check this out. Take that mother f*****. I still haven't tried firing it up with all the RAM in it. This is the RAM strategy. OK, two sticks here, 10 on the table. And I haven't tried any of the eBay chips because I wanted you guys to come along for the ride. Let's find out if anything works. I'm like half excited and half terrified. I really hope these work because I am almost definitely passed any kind of buyer assurance deadline through eBay at this point or PayPal. I really, really hope this thing works. Now that I've had the board booted up, if this doesn't work, then I'm pretty sure that I got scanned. One thing I did find out is that some of my posting issues may have simply been related to memory training. And if I had just waited longer, which wasn't something that was easy to do when I was holding CPUs into the sockets. This is not a solid indication right now that things are going to go well, though. I actually hate that this TV has like such a pretty screen saver. When I see a thing change, I'm like, hey, whoa, whoa, whoa, OK, hold on a minute here. Whoa. OK. They booted. Genuine Intel CPU, zero thousand percent at. Flipping brilliant. OK. All right. Let's fire this baby up. So our last CPU got a score of about seven thousand in Cinebench. And that was with retail eighty one eighty chips. I've seen engineering samples that have more information than this. But what we do know is the base speed of two point one gigahertz. We know that there are twenty eight cores. That's really exciting. So these are probably what they said they were, which is eighty one seventy six is. Yep. Xeon platinum eighty one seventy six is the eBay Gambit worked. Nice. And these are qualifying samples, which I believe means generally they are pretty close to retail chips. So this is not the be all and end all of benchmarks, certainly. But we can get an idea of whether we're close to what we have with the retail eighty one eighty. I want to see what it turbos to. Not bad. Not bad at all. OK. So that's a significantly lower turbo speed. We were turboing up around three gigahertz with the other one. And our lower score does reflect that. But that's a hell of a chip for what we paid for it. Now let's try the mystery meat platinum eighty one thirty six time. Is this a straight up scam? Remember, this is the one where the eBay seller was unable to confirm anything about it. Unable. OK. Yeah, this is not looking promising so far. It's just been on AF the whole time. You might say it would be disappointing. Damn. Wonder if I can still file a dispute. Here it is. Ah, ah, shoot. Return this item is not there anymore. Oh, that's not good. Can I even leave feedback? No, I can't. I can't even leave feedback anymore. Wait, no. View similar items. Twenty six hundred US dollars plus shipping. Brilliant. So I guess the lesson we learned then is buying engineering sample processors off eBay can work or it can super not. But if you order a part number that doesn't exist at all, then the odds of it super not working from our sample size of one seem to be pretty good. Thanks to audible for sponsoring this video.
