  1. If you're a 4-year EE grad, and you're being interviewed for a job where they're asking you those sorts of questions, you're probably not making appropriate use of your background. OTOH, if you're a 4-year EE grad, and you're having trouble coming up with answers to those questions in your head, on-the-fly, then I'd have to question how well you really did in EE. Overclocking in an interview question at an engineering firm? Seriously? Maybe at Linus Media Group or something like that, but overclocking has almost zero place at an engineering firm, lol.
  2. If there's microcode support, you could do an i7-5775R/C. But a giant waste of money to upgrade to that. Keep your existing chip.
  3. No, you really don't want to try and substitute something else for a proper thermal pad. You can order thermal pad material from the various Chinese vendors for $5-$10. Make sure you get the right thickness. That is, if you can't re-use what you already have.
  4. Screens aren't that expensive and if you have an i7-6700HQ, you have a pretty smokin' laptop. It may very well be still under warranty. Does your school have loaner laptops?
  5. Look in the BIOS/firmware menus for something that's called a 'Watchdog'. Disable that.
  6. The 'problem' with that is that most people don't really understand what 'low-power' means in the context of Intel's chips. For instance, the i7-3770 comes in 3 versions. The i7-3770 (77W), i7-3770S (65W), and i7-3770T (45W). So the best chip to buy if you're running a 24/7 server is the 3770T, right? *nope*. All 3 chips, identically loaded with appropriate power settings in the PC's software (ie: cpufreq in Linux, or the equivalent in Windows), will consume exactly the same amount of power. The 3770T/3770S chips have their top-end deliberately derated so that they can be integrated into "thermally challenged" platforms like the iMac. Or put into rack servers where there might be a legitimate need for thermal de-rating to get an overall rack to meet a certain power spec. Intel gives the buyer a discount on the chip, knowing that a lower performing chip will probably have a shorter-life-cycle than the "full-power version". The vendor can also save money on other aspects of the motherboard by, for instance, shaving a couple voltage regulators and capacitors out of the design. But if you're DIY'ing a server, going with a "low power" chip basically gets you almost nothing. The Skylake chips, run at extremely low levels of utilization, are quite competitive with Atoms. And if you ever need higher levels of utilization (ie: you run more applications on such a machine), then the power is there. With an Atom, you basically end up running it full-blast, or throwing it out and buying something faster. This "servethehome" article pretty much sums it up: https://www.servethehome.com/intel-atom-c2550-power-consumption-comparison/ Now, yes, the green bar on the Pentium G2120 chip is higher at the end, but the Pentium G2120 chip is doing a lot more processing than any of those other chips.
  7. Intel's been making ARM products for years. And Intel drops prices all the time. Do you not remember the severe drop in prices on the Sandy Bridge products ostensibly to put AMD into death throes? Even E5's aren't that expensive compared to what historically a server CPU cost, and they certainly aren't able to, due to competitive pressures, increase prices, even when they deliver a much better product than previous. And let's not get into all the areas that Intel's been completely and utterly spanked over the years. WiFi. LTE baseband modems. SSDs. Software of almost all kinds (the McAfee acquisition should be written down to $0 because there's not one iota of value delivered to Intel there). Motherboards.
  8. Gotta disagree here strongly. A lot can happen in 5 years and there's lots of reasons, namely the heavy use of portable code, that plays in favour of the non-x86 players that can deliver solutions at low cost. Last time around, too many customers were reliant on x86 binaries. Now a large chunk of the ecosystem isn't. Yes, but they have to charge the big bucks because they have all that "other" engineering to amortize over a few chips. That's why the chips are expensive.
  9. I strongly disagree. Intel was under significant pressure on their server pricing lines during the DEC Alpha AXP days in the 1990s. And for all we know, an E5 might be twice the money today if they didn't fear ARM getting serious about being in the market. And volume really is the issue. There's so much engineering to be amortized over limited POWER production volumes. Incremental costs are minimal, so if IBM can get the platform out there and generate some acceptance, it bolsters their ecosystem.
  10. Let's say you're Amazon or Google and you're buying half a million processors a year at $2000 a piece to support your cloud computing infrastructure. If you can convince Intel that competition is just around the corner, maybe Intel will be willing to discount those to $1800. Or cut you some other concessions like custom tweaks. The more leverage the customers have against Intel, the more they can push prices down. That's why I suggested that they might be interested in covertly funding development on other platforms.
  11. I use Bell and T-Mobile SIMs in Canada (and the US, particularly east and west coasts) on a Sierra Wireless MC7700. The costs are reasonable, with the T-Mobile passes being $10/week (in US currency). There's Fido 3gb data-only SIMs (marketed for tablets) which are like $20/month now pre-paid. Lots of options if you have the radio in your laptop.
  12. Crank up the volumes, and it could take a run against the top end of the E5/E7 lines. Which is entirely the point instead of it just being an obscure line in the IBM catalogue that goes into their big iron or whatever they're using them for. The point is, the more alternatives that are available, the tighter that the screws can be applied to Intel.
  13. Find yourself a cheap open box/refurb business laptop. ie: Dell Latitude E6440, E7440, E7450. I highly doubt there's anything in undergrad engineering that really needs anything major CPU-wise, and GPU's definitely are not necessary. Most engineering school these days is spent with software like Excel.
  14. Just because your laptop has a SIM card slot, doesn't mean that the laptop actually has the electronics to do anything with it. Unless you know your laptop has been configured with a 4G LTE radio of some sort (ie: Sierra Wireless MC or EM-series is very popular), it probably doesn't, even though the SIM card reader is present. On that note, Microsoft is close to launching a service like this as well, with partnerships with the various cell carriers, but Microsoft branding, Microsoft billing, and Microsoft SIM card. There's even an app for Windows 10 that lets you sign up for it in the app store.
  15. Strangely enough, it wouldn't surprise me if one of the big cloud companies steps up to the plate and covertly provides funding. They spend big, big bucks on Intel CPU's each year, and anything that stresses Intel into lowering their prices, particularly on the high-end gear, will be to their advantage. For such low volume hardware, the price, if they can actually deliver, is basically dirt cheap.
  16. Do you ever think this machine will be a server, even if not initially?
  17. Intel apparently dropped microcode support for Xeons in the Z170 and other 'consumer' chipsets. You can use i-Series processors in the Xeon E3 boards, but not vice versa as of the "Skylake" generation.
  18. If you care about lifespan and are buying a Dell laptop, usually the Latitude series is a better way to go. "Consumer" versus "business" quality. Sure, the Latitudes aren't as flashy, and their feature set can be slightly more conservative (ie: dGPU's aren't often found!), but they have some key features, such as docking capability, more rugged cases, and usually greater use of metallic components that increase longevity. Also, 5 years from now, eBay will be full of parts for Latitudes that you can buy for a song. While those XPS parts probably will be more elusive. Think things like rubber bumpers, keyboards, etc. I know the 'marketing' of the Latitudes is towards businesses and business users, but arguably someone taking their laptop to school every day probably needs a more ruggedly/solidly built laptop than even most business users. Especially if they're intending to rely upon such for a longer lifecycle.

    Performance wise, nearly all of the currently shipping 500gb-class/1Tb class SSDs for SATA3 have performance that is such that an end-user probably wouldn't notice the difference in a typical 'consumer' application. The differences may be with respect to reliability and longevity, as well as warranties and potential customer support/ancillary software packages.
  20. A good place to start would be the Supermicro website. https://www.supermicro.com/products/motherboard/
  21. Are you sure the SSD isn't your current boot drive?
  22. I doubt any PS2 came with a 3.3V power supply as the line was phased out long before the time of 3.3V chips (ie: Pentium-90 P54). So that would be another problem as well with fitting a modern ATX motherboard.
  23. For starters, virtual machines often do a very poor job of running DOS programs, particularly if they have significant amounts of assembly or do anything fancy with memory management.
  24. 9.7", not 7" on that one. The 7" tablet market is pretty bare :(. v410, Google Nexus 7 Refresh, not many good options :(. The v410 needs more RAM unfortunately.
