  1. I don't think it's a big deal. First it's not 100% confirmed, and secondly it's not new. Don't think it's unusual for Intel or AMD to create a non retail chip. Sometimes chips intended for speciality markets or limited editions are made only for OEM's. OEM's would buy them for "boutique" systems. Basically you and I would just ignore it. Don't think it's anything new. Plenty more chips to go around for you and I. Who knows, if the system builders cant sell there highly priced systems with fancy CPU's Intel might switch it to retail.
  2. 3770K is perfectly capable of running OCCT, Prime 95 or any of the stress tests. All of the aforementioned existed well before the 3770K was released. The only thing to watch out for is AVX instruction sets. The latest version of Prime runs AVX, as does OCCT etc. AVX stresses the CPU to the extreme and more heat is generated. Not an issue with no overclock, but if you overclock and run AVX, especially with a less than top-notch cooler, you could generate very high temps. AVX can be disabled in Prime (or use the older version that didn't run AVX), Aida 64, and I believe in OCCT. I wasn't saying you should stress your CPU to the max to determine if it's running with MCE on or off, you just need to put it under load. A stress test will do that. I would say just run CineBench. And monitor the cores with HWMonitor. You will be able to see what frequency it's running at, the voltage and temps. Plus a myriad of other useful data. Or just run the sim, or any other application that puts it under load. For overclocking, I run Cinebench for a quick stability test after each nudge up in frequency and when I'm at the max my CPU seems to be capable of, I run Asus ROG RealBench for an hour or so. That's all I usually need. The best test of stability is the apps you usually run daily. Aida64 I sometimes run, with FPU off it doesn't run AVX, with FPU on it does run AVX so temps will be higher.
  4. No, that's the non turbo speed. It wont be. Turbo will be boosting one of the cores to 3.9 GHz. The way to tell is to run a stress test and monitor the cores with HWMonitor.
  5. H80 isn't top-notch. I would upgrade it if you intend to overclock. And if its 6 years old the pump will have had plenty of wear. The cooler wont leak when removed unless it's defective. They aren't as delicate as you think. Personally I'm an air cooler fan. Noctua in particular.
  6. What kind of water cooling solution. If an AIO, it's straight forward. If a custom loop with soft tubing can also be straightforward. If a custom loop with rigid tubing then the entire system would have to be drained. A CPU that has been in place for 6 years is not an issue. Once the cooler has been removed it's simplicity itself. Lift the latch and remove CPU. Easy. Taking care not to bend the pins on the motherboard is common sense of course. I take it you didn't build the system you have now and are limited in experience in this respect? If so, there's plenty of tutorial videos on the internet and the motherboard manual itself will advise you on how to install or remove the CPU. Well the latest CPU bought by serious gamers/enthusiasts, the 9900K, is something like 39% faster in single core performance and 180% faster multi-core performance. So whether you should buy a new PC is something you must decide based on what you want from the sim and how much money you are prepared to spend. You must decide if you want the best performance you can squeeze from the sim or if you are happy with what a new motherboard and overcloking your current 3770K will provide. Consider that overclocking will not be any kind of miracle. Overclocking is generally linear in a reasonably well balanced system devoid of serious bottlenecks. A high overclock from stock 3.6 to 4.5 GHz is 25%. So if the sim is averaging 30 frames per second you are looking at 37 frames per second or so. And the silicon lottery of course may result in a lower overclock than that. A new graphics card with your system will also result in a performance boost of course, as will; faster RAM to a degree. A complicating factor I should mention, as this is an Ivy Bridge CPU, is that manufacturers were in the habit of turning MCE on by default with XMP. So it may be that your CPU is already running at max Turbo on all cores. In which case the 37 frames per second I mentioned in the overclock scenario above would be less than that.
  7. Others have had this issue. Their suggestions may help you get into the BIOS. If and when you do, update the BIOS. You may then find you can access the BIOS consistently and can overclock. Removing the graphics card and relying on the CPU's on-board graphics worked for some. If that works, as I said, update the BIOS. For the USB issue, one guy suggested "switch over the PCIE Rom state to Legacy ROM". If still no luck, email Gigabyte, I'm sure their tech guys will offer a suggestion, even if it's beyond the warranty.
  8. What an innovative design. Great boards EVGA. This one designed in collaboration with overclocker Kingpin apparently.
  9. 8700K delidded. Run without overclock as I'm not simming, but runs at 5 GHz on all cores easy. 5.2 GHz max with HT off. Cooling NH-D15S.
  10. Nope... or more accurately no and yes. 🙂 Turbo for 9900K is 5 GHz, but that's only on two cores. And only if it's just those two cores active. As soon as other crores fire up the frequency of all cores drops. That's how Intel Turbo works. So in the Cinebench run with all cores active, the 9900K will have dropped to it's minimum Turbo frequency on all cores of 3.6 GHz. Worth mentioning that the AMD CPU was an engineering sample not running at it's final frequency. So given that it was slightly ahead of the Intel 9900K in Cinebench, we can expect it to be further still ahead when it's up to the frequency it will ship at. How far ahead is impossible to know because AMD didn't tell us what frequency the engineering sample was running at. Same for the power consumption. 30% better than the Intel part, but when the AMD CPU it up at it's final frequency and voltage, we can expect power consumption to drop down from that 30% advantage. Should still be significantly better than the 9900K though.
  11. Glad to hear it Noel. Coming from the UK of course, we have no experience of what you have gone through. Must have been a nightmare. Surprisingly we do get quite a few tornado's in the UK. Little mini tornadoes, something like 30 per year are recorded. They rarely cause much damage though. Flooding of course, now more common. And believe it or not the occasional earth tremor when something moves in the North Sea, or old mine workings shift. I have experienced a few tremors over the years, the last one bad enough to wake my family up and swing open wardrobe doors. But who am I to talk about earth tremors when you live in California... 😀
  12. No, nor me. Not much point for 10 degrees. If it was a easy as TIM, then I might, but there is a bit more effort with solder, carving it off with a blade and then sanding the die. Yep, from my understanding of component degradation I would agree with that, re heat. RAM is rarely an issue re temp of course. The point re CPU degradation and heat is that its hard to estimate just how much degradation would be sustained. Personally though, in my experience, I don't think 10 to 15 degrees or so is that relevant. I would "guess" we would have to be dealing with temps at 90, daily, to shorten the lifespan to a degree that it failed just after the warranty period. If it's not throttling back its regarded as within the normal range, and designed to last the 3 year warranty period or more. I would say most CPU's that are up at 80 degrees or less, should last well past the warranty period and still be going strong by the time most enthusiasts are ready to upgrade. In fact I had an old i7 920 quite a few years ago that was a great overclocker, I sold it to a friend. It's still going strong after, oh god, must be 8 years at least. Been overclocked pretty high right from new. No sign of degradation. So yes, I agree that in theory a cooler CPU undergoes less degradation and should, theoretically, have a longer lifespan. But I think we over estimate how fast degradation takes place. And under estimate how warm a CPU can be without significant degradation.
  13. Oh my god, sorry to hear that Noel. Was your home damaged? That must have been very scary.
  14. Quite a few have delidded the 9900K and achieved these results. As I said, the solder is applied very thick, so not surprising that replacing it with a THIN layer of liquid metal drops temps. See video below re temps... 7:59 in video, a 10 degree drop in temp with liquid metal instead of solder. In addition, the 9900K die is also very thick, 0.42 for 8700K and 0.87 for 9900K, thus, lapping that down so it is thinner drops temps further. Lapping the die temps at 11:22 in video.
  15. Sorry about all the quoting Noel, and I'm playing devils advocate a bit with my comments. 🙂 And what was the temperature of the board, RAM and GPU prior to your air con solution? What I'm getting at is that most of us over cool our PC's. I'm trying to get a handle on whether I myself would deem the temps prior to your air con solution an issue or not. I would disagree, delidding is feasible on all CPU's with TIM rather than solder. And pretty much all coolers can be used on alternative CPU's. Most people don't want that sort of realism though. They want to enjoy the sim in comfort without excessive noise. Plus of course they don't just engage in flight sim, they play other games too. But at the end of the day, the main thing is that you yourself are happy with your set up and it's right for you. 80F is what, 26C? Pretty much the same as in the UK, on a hot summers day. We get quite a few of them these days. We don't have air con here, except in business premises. Our issue is keeping warm in the winter, so just central heating. My approach is to take into consideration the max temp I am likely to see in the summer, and overclock until I ma at a safe CPU temp based on that max ambient, summer temp. D15S, not D14. I wasn't suggesting you adopt the D15, just pointing out how much the drop in temp is with delidding and the D15 compared with your air con solution. Well to be honest Noel, there are a number of reasons why they don't. Many live in cooler climates were it's simply not necessary, and a standard cooling solution, either a high end air cooler or AIO is perfectly adequate. In addition, if living in a warmer climate, air con is usually installed in the house anyway, and ambient temp is lower enough to not be an issue. They wont be dropping their system temps as low as you are, by blasting cold air directly into the PC, but to be honest, I'm still not sure that's necessary. The other point of course, as alluded to above, is that what I do, and I'm sure others, is to take note of the max ambient temp I am likely to see in the summer. I then overclock with this temp in mind, and make sure I have enough margin to be in the safe temp zone on a hot summers day. Overclock is then lower, but as you know, overclocking is generally linear, so a few hundred megahertz lower overclock is minimal in terms of frame rate. So my preference in your position, would be to overclock lower rather than use the air con solution.
