Cleaning the dust out of an Xbox 360 and decided to replace the thermal paste on the CPU die and I had some Arctic Silver Céramique lying around. Application was uneventful, but then I got curious and looked up the ingredients of Céramique, and it contains zinc oxide, boron nitride, and aluminium oxide. Zinc oxide is relatively soft, but boron nitride and aluminium oxide are relatively hard and have the potential to leave scratches in the CPU die, which I don't want.

Summary In a recent study "Semiconductors, the Supply Chain, and Cyber Security 2021" done by BlueVoyant, the majority of chip companies in the world show signs of already being hacked, thanks to monitoring malicious traffic coming out of them. There goes the neighborhood. Quotes My thoughts This is what happens when "we're too big, they won't go after us" and "the intern set it up 5 years ago" and "not my job" and "security isn't profitable" happen. Take a lesson from this if you've got a company or an IT department asking for security funding and support that, or make sure companies you're associated with have a good and security minded IT consultant company that does active patches, backups, mitigations, etc. I have hope that this sounds worse than it is, since I know at least a couple of these companies are of a size where they may run internal honey pots. But any way you look at it, this is pretty damning, and looks really bad for trusting the security of hardware for the next couple generations, or at least expecting massive IP stealing and copying. If you think your favorite company isn't included...it probably is. The industry is small, even if the players are large.

TSMC Clarifies Apple's UltraFusion Chip-to-Chip Interconnect
DANK_AS_gay posted a topic in Tech News
Summary TSMC described exactly how Apple has engineered the "UltraFusion" chip interconnect. It seems to be an expensive, relatively complicated way to achieve chip interconnection, but with the added benefit of ridiculous speeds. Quotes My thoughts I would never have thought that Apple would let this info leak, and I find it interesting that they did not completely reinvent the wheel here. I wonder if Apple will use this later, and why. (Besides a future Ultra chip, or maybe even a desktop chip) Sources https://www.tomshardware.com/news/tsmc-clarifies-apple-ultrafusion-chip-to-chip-interconnect -
I'm currently working on an essay about how technology has become more affordable and opened the doors to different creative processes over the last 20 years, and have spent countless hours researching processors new and old. The last bit of information I need is a percentage yield rate for the Core i9 13900K, that's to say the average percentage of functional processors from each silicone wafer. It doesn't need to be directly from intel, but I don't have the knowledge to make an estimate, so any information would be appreciated. Thanks!

The new Apple M1 chip is amazing! It is the brand new chip that will be shipping in the brand new Macs that will be coming out later this year! According to Apple’s Official Press Release: What do I think about the new chip? The new chip is amazing! Apple says that it is the first chip to use the 5-nanometer process! It is 6x better in GPU performance and 3.5x faster in CPU performance than regular laptop chips! From that, this chip seems like on of the best chips to come out on the market!

Hi all, My name is Xander, I'm an Australian student in my senior year of high school. As part of the Australian Curriculum I need to take part in a Research Project; a compiled folio of information to answer an open ended question. I am looking into Silicon Processor Technology and what limits it has, how far it can be taken and what are future contenders for Processor materials. A segment of the folio is an interview with a professional, and I see the community here as a large enough pool to be considered professional. My main reason for the email is to ask if you'd like to answer 10 short questions as this would greatly aid my Research Project (attached as a Word Document) Look forward to hearing from you. Regards, Xander Interview Questions.docx

Hi all, Sorry to post this again but the survey here is absolutely vital to my senior year of schooling (so much so that I am required to pass this assignment to pass this year) You don't need to know a whole lot about processors at all, or anything even. As any response is useful to gain opinions and information from a wide range of audiences. Regards, Icarus

Hello guys, I just thought of this... how can a software read ASIC quality to that accuracy degree? What process goes into benchmarking a GPU's ASIC exactly? I wanted to know just out of curiosity. Thanks for any answers

Hello, so..i'm retarded. I literally broke an old ATI chip from a motherboard (old hp laptop) in half. This weird metallic dust came on the air. I tried to clean it off. I could see it using a bright light. It looked like the stuff from the CPU die (or GPU die). I think i removed it from my table, but i'm having a hard time removing it from my hands. I can still see it under a bright light. Soap doesn't seem to work. Will it go away by itself or should I do something? Please reply quickly, Thank You TeamLTG

Hey everyone, as the title suggests, Silicon Lottery Percentages. I know what the silicon lottery is and how it works, but one thing I'm unsure of is the percentages - as in, how bloody lucky you are if your overclock is x% over the default clocks. So I was wondering if anyone here could shed some information on this. What percentage boundaries would be considered good, better, best, or Holy S**t? Specifically as to why I want to know. I've had my i5 for around 23 months now and am looking to upgrade. Since it can overclock, I've had it overclocked since I've had it. Up until now, its been at around 4.5GHz. Only recently, I've decided to push it to what I find is its max on AIR. My CPU: Intel Core i5 4690K Cooling solution: Phanteks PH-TC14-PE (Push/Pull) Stock Speeds - 3500mhz (3.5GHz) My overclock - 4898mhz (give it a little rounding, 4.9GHz) Equating to a 40% overclock (I think) - rock solid stable (Well, I've experienced no crashes and I've been at this speed for about a week now), at 1.31v (I know CPUz is saying 0.952v, but I've probably left SpeedStep on ) Is this a good overclock for the voltage and for what the chip is? Please let me know Thanks.

Surprised this hasn't been posted yet.. So, for some time rumors have flown that Threadripper is made of "failed" Epyc chips, as there are only two of the four dies in use, but AMD has finally spoken up to clarify things. As it turns out, two of the dies are inert and do not even contain transistors. Basically, they are just spacers, there for structural integrity and nothing else.

hello i have a general question, a class mate of mine is telling all kind of wonderfull story's that i do not think are true but one story in perticulair interested me. he sad that he baked a egg on a amd cpu (a old one so it wouldn't shut off) and got it to 200 c. and i could not find out wy is was not true. silocon can be 1000 c so wy doesn't it run that hot? can you guys help me out? tnx kthxby

Hey there, My PC is running an i7-4770K on an MSI Z87-GD65 Gaming motherboard, with Kingston 2400MHz 16GB (2x8GB) RAM, and a 980Ti graphics card from EVGA. I have been overclocking for a while, but never understood all aspects of it. I have been running my processor at 4.2GHz for over a year, and it has never gotten a blue screen, but recently I decided to attempt an even higher overclock, which didn't work. I was stupid enough to forget to save the overclock I had at 4.2GHz, and now I can't seem to go higher than 4.1 GHz. I might have lost the Silicon Lottery, but I know that I should be able to reach at least 4.2 GHz. I've tried all kinds of settings for both memory and CPU, and it doesn't seem to improve it much. The PC wont stay on for more than 2-3 minutes. I'm pretty lost right now, and I'm just wondering what to do next, so I would appreciate any help I could get. Can't remember my previous 4.2 GHz voltage, but I have tried up to 1,275V. Thanks! (Oh, and I'm running a Corsair H100i cooler)

So, i've had my 9900K for a while, and at stock it's occasionally crashed, that was fixed by adding an offset of +50mV to the vCore. Kinda decided i would have a go at least getting it to 5ghz across all cores, rather than just a single core turbo. Now i'm at 5.0 GHz, and 1.325v isn't even stable, trying 1.350 for the lulz now, i run prime95 26.6 for literally 30 seconds and the system will hard lock-up and i have to turn power off and on again. I've got a 360mm AIO (thermaltake water 3.0 ultimate 360mm), and i'm watching temps and those aren't brilliant but it isn't going over 90c. Now i tried to get stock clocks working properly instead, and found the only way to have it stable on stock volts with no offset, is to disable c-states. That's all fine, i can put up with a little extra idle power draw, except now it only turbo boosts to 4.7, though it is then rock solid, so clearly my chip just is not fully stable in any form above 4.7ghz, even at its own stock settings. Should I RMA it? Another thing i've noticed is that core 2 and 8 run about 10c cooler than all the other cores.

Given the fact that we're all going to say goodbye to Bootcamp, I was wondering about the possibility of having some kind of virtual machine software running windows on arm. What do you guys think about that?

So I overclocked my Ryzen 5 1600x to 4.2Ghz and only at 1.375V, I was wondering if that was pretty good. On Cinebench R15 I got scores as follows, OpenGL 110.74 FPS (GTX 1060), Ref. Match 99.6%, CPU Multi Core 1365 cb, CPU Single Core 167 cb, MP Ratio 8.18 x. I want to also know if those scores are good. Also according to Ryzen Master it says my temps on my CPU Idle are around 38c. Under full load it runs in the high 50s to low 60s. Does that all seem to check out?

I was searching for rare intel chips on ebay. And I came across something rather weird and what I would think is weird. I also think it would be a great collecctable for any true tech fan. How real are these, I am not sure, would be great if Linus or a memeber of his team to check it out, also great thing for their tech channel to own. I will provide a link to them. Whats your guys views on these, clearly they are no use to anyone, would be more a thing you would put into a cabinet to look at. I always thought these would be on larger disks, and those not used distroyed, but saying that Linus managed to get his hands on a GPU from Intel, so anything is possible. <eBay Link Removed> Has anyone on this forum ever bought one, how can we verifie they are real?? Apart from to look at, what else would there be to own one.

So I've never had -too- much luck when it comes to overclocking my cards. I got my original Titan X to around 1300 MHz. Not bad but I'd consider that pretty average really. But this new EVGA 1080SC seems to be like a real winner. Can others share their overclocking results so I can get a better idea of what is normal? The thing is advertised as 1708 MHz with a boost of 1847 MHz but I've managed to get mine all the way up to 2700 MHz! Any further and I start noticing some artifacting... But yea, just really surprised I can achieve such a clock on air. Edit (I was a noob. I was getting nowhere near this clock. Scroll below to see explanation / stupidity)

IBM announced today they have figured out how to replace silicon transistors with carbon nanotube analogs. The full study is going to be published tomorrow in "SCIENCE" SO far this is only replacing the transistors, this is not an entire assembly of carbon nanotubes, so there are still areas that can be improved, and the nanotubes themselves can be shrunk down further as well. IF this scales up it could fill in some of the gaps for processor assembly and maintaining the performance improvements over time we have come to expect. Hopefully more info will come to light on the effects these new processes will have on power, heat, and costs. UPDATE: The full article is behind a paywall if anyone knows a location of the full PDF it would be appreciated.

So i just recently built my first computer which has a 4790k and gtx 780 I am interested in what kind of overclocking you might expect from these chips my CPU has a coolermaster hyper 212 evo my GPU has a EVGA non-referance cooler (ACX)

Should be noted that I have a 5820K and a H100iGTX, with an ASUS X99-E WS and a GTX 980. (Build log in sig) So my chip handles 4.5Ghz at 1.35V STABLE (Past 48 Hours) at around 70 Degrees. I'm afraid of going any higher than 1.4V Because after 1.4, it gets over 80C which is my limit for how hot I will run this chip. No multipliers work after 45, So I called that chips journey an end. But STILL thats 4.5GHz on 6 Cores. Which is enough for me. (Mind you that 3.3 was insane for me to begin with) Linus's review chip handled 4.7, so this raises the question for me: How did I do in the Silicon Lottery?

My Corsair 200r fans that came with the case seem to cause some vibrations when the RPM gets up. My hard drive could be a factor also but I feel it is the fans. The vibrations shake the wires up a bit making them vibrate against my case causing an annoying buzzing sound. Instead of replacing the fans, I thought of buying new rubber/silicon mounts for them. But I'm not sure which kind or brand I should be getting or if it even matters.

Many of us have probably heard something called a easter egg, where creators hide a hidden message or something special in their works. Well some take that easter egg to a whole new level, by putting them to place that might never be found. This is where Chipworks comes in with their fancy high-tech electron microsope that scan all the individual layers in a silicon to see what's truly inside like how the chip is made and sometimes they find a very nice suprise. So without further babbling, here is the image of what they found in the silicon of a Infineon PMB5703 used in the Samsung Galaxy Tab. http://www.wired.com/2011/03/silicon-art-samsung/ http://www.geek.com/chips/galaxy-tab-infineon-rf-chip-contains-fantastic-silicon-art-1328213/
