  1. Nics in m2 slots?

    You can buy m.2 to pci-e x4 or pci-e x1 risers / adapters, and then you can put any pci-e card in it. So for example you could buy a regular half height pci-e x1 or pci-e x4 network card and that would leave enough room to install it on the back of the case and have room for the riser connector. For example: https://www.ebay.com/itm/NGFF-to-PCI-Express-4x-slot-Adapter-M-Key-M-2-to-PCI-e-x4-interface-Riser-Card-/121912960082 Or https://www.dhgate.com/product/high-quality-m-2-ngff-to-pci-e-x4-x1-slot/404647158.html or https://www.dhgate.com/product/m2-to-pci-e-4x-slot-card-adapter-ngff-m-2/401211101.html?recinfo=8,103,4#cppd-4-5|null:103:r0727704002 This creates a pci-e x4 slot from the m.2 connector. The extra power connector is there to insert 12v into the pci-e x4 slot, if you decide to stick something directly in that slot. By default, the m.2 connector only has 3.3v. Normally the idea of these is to insert regular wi-fi cards which don't use more than a few watts anyway. You can combine that with a pci-e riser adapter things like the ones used for mining and then you don't need that power adapter cable, because the mining risers only use the data wires in the slot, they have separate power connectors on the x16 sides and voltage regulators that create the 3.3v for the cards. So for example : https://www.ebay.com/itm/4pin-USB-3-0-Pci-PCI-E-Express-1x-To-16x-Extender-Riser-Card-Adapter-Power-Cable/183020462031?hash=item2a9cde9fcf:g:gocAAOSwI~taXXhJ The x1 card you plug in the x4 slot from the adapter, and then the usb cable connects the m.2 slot to the x16 slot of the riser, in which you can plug any card. If you use a half height network card, it should still leave you enough room for the riser slot to sit above the motherboard slots and still have ability to screw the network card directly on the back slot locations. Note that there's no guarantee that the bios will actually accept (work with) anything but m.2 SSDs in those m.2 connectors. Normally it shouldn't be a problem. Ideally, you would get one of these adapter things that combine both, meaning have the m.2 circuit board with a usb3 connector or some ribbon cable connector (because usb 3 cable doesn't have enough wires in it to carry 4 pci-e lanes) , then have the second pcb with x1 or x4 slot and the voltage regulators required to bring 12v and 3.3v to that riser board. But I guess it would make the whole thing too expensive to be sold, and the demand may be too small.
  2. Basic soldering iron

    That's a lousy soldering station (without feedback from the tip). It's not really worth the money. You can check out Farnell , they ship to various countries in Europe from EU warehouses: http://uk.farnell.com/w/c/tools-production-supplies/soldering-stations-accessories/soldering-stations/soldering-stations/prl/results?sort=P_PRICE Check RS-Components as well : http://www.rs-components.com/index.html And TME.EU has cheap solder and fluxes and maybe also soldering stations https://tme.eu You basically have cheap soldering stations which have some knob controlling the temperature, but they don't don't actually control temperature, the knob just controls the amount of electricity that goes into the tip and the setting on the knob just guesses what the temperature would be. So for example, if you set it at 300 degrees Celsius and you try to solder a very thin wire, then it would work. But, if you try to solder a thicker wire or some big component lead on a circuit board (which has a lot of copper that absorbs the heat from the iron tip), the energy pumped into the iron tip won't be enough to maintain the temperature at 250-300c and actually solder, because the leads and the circuit board will act like a heatsink and absorb the heat.. so these controls are very rudimentary and not very helpful. The amount of energy going into the top is constant, it doesn't vary, you set the peak amount of energy with that knob. If you're fine with that, you may as well go with the cheapest $13 uk pounds Duratool station. The next level is proper soldering stations which have a temperature sensor in the tip and the knob or buttons actually control the temperature. You set the temperature and the station reads the actual temperature of the tip and pumps energy in varying amounts to keep the temperature there. So if you put the tip on some circuit board which sucks up the heat and cools the tip suddently, the station reacts fast and pumps a burst of energy to bring the temperature back to the setting and as soon as you raise the tip and heat isn't sucked anymore from the tip, the station lowers the amount of energy pumped. So it's dynamic power control, and knob sets temperature. Farnell sells Tenma branded stations which are actually rebranded Atten stations, you have there Tenma AT60D-UK at 33 uk pounds (Atten AT60 rebrand) or Tenma SS-207BC-F ( which I think is a rebranded Yihua Hakko 936 clone ) at 35 uk pounds or Tenma 21-10115 UK (another rebranded Atten model) at 38.5 pounds These come with UK plugs but you can either change the plug or use UK to EU plug adapter or change the whole cable (it's regular pc power cable on some) They also use the classic Hakko tips you can buy on eBay for something like 4-5$ for 10 tips and the classic Hakko clone handpieces you can buy from eBay and so on... As for solder wires, yes, what you buy does make a difference, i can write long posts about the differences, let me know if you really are interested and want to me to suggest something to keep it short, look for 0.7mm thick or thinner (i prefer 0.56mm thick), buy 60/40 or 63/37 or 63/36/2 (overkill and expensive) solder, with at least 2% flux , ideally no-clean or RA or RMA flux (rosin core mildy activated or activated, with or without halides) , stay away from water soluble fluxes (as they're NOT what you may think from the words) Good brands Multicore, Stannol, Kester, Edsyn , Henkel ..
  3. Is this the right way to put on thermal paste?

    A pea sized blob, a thin line, an x , it really doesn't matter, as long as you don't go overboard with the paste. The paste is meant to be a thin layer between the heatsink and the metal surface of the cpu... so often less is better.
  4. How often does nvidia restock their cards?

    nvidia doesn't do anything, they just make chips and sell them by the thousands to companies making video cards. Those companies make cards by the thousands and sell them to distributors by the thousands, and ship them usually to distributors by shipping containers because it's cheaper than shipping by air (and it takes up to 2-3 weeks for the cards to reach the country by ships) So often cards come in big batches of a thousands of pieces (multiple shipping containers) to a distributor which then sends them to various IT stores which then sell them by piece.
  5. RYZEN CPUs

    The 2400g is just slightly better than Ryzen 5 1400, because of the slightly improved memory controller (works a bit better with memory sticks that run at 2933 Mhz or higher) and the higher frequencies. Ryzen 5 1400 runs at 3.2 Ghz default, boosts to 3.4 Ghz Ryzen 5 2400g runs at 3.6 ghz default, boosts to 3.9 ghz Though you can overclock both to run at 3.9 ghz on all cores. Ryzen 5 1600 has six cores, so it would be better than both, even though each core runs at 3.2 ghz by default and boosts to 3.6 ghz when possible. The graphics on the 2400g are between GT1030 and GT1050 in performance, so the 1050 ti will be higher performance and has its own memory, so you don't need to reserve 1-2 GB of computer ram for the graphics, leaving more ram for games and applications.
  6. Ah, sorry, I thought it was about Threadripper, got this mixed with the mining thread, thought it was talking about threadripper and mining monero on it. My bad. Yes, the APU only gives out 8 pci-e 3.0 lanes for the video card, 4 to m.2 and 4 to chipset but that's really enough for a video card. There's minimal performance difference going to pci-e v3.0 x16. Still... b350 chipsets create 6 pci-e v2.0 lanes and the x370 chipses create 8 lanes. Motherboards will use maybe one or two of those lanes to connect internal things like onboard sound card and network cards, but on ATX boards, you would still have at least a pci-e x4 and 2-3 pci-e x1 slots, so you'd have maybe 4-5 pci-e slots in which to plug video cards if you want to mine, or even just to have two video cards in a mGPU configuration (one directly to APU and one plugged in pci-e x4 slot from chipset)
  7. The cpu has 64 pci-e lanes. Those 64 lanes are split into x4 going to chipset and 60 "general purpose" and motherboard makers usually use 3 x4 for up to 3 m.2 , and the rest for slots , so you typically have 48 lanes split across 6-8 slots. With 6 slots, you have 6 x8 slots, for a total of 48 lanes + 12 lanes for m.2 + 4 lanes to chipset = 64 lanes. Also the beauty of Threadripper systems is that each x16 can be divided in up to 8 devices, combinations of x1 , x4 and x8 devices, so it should be fairly easy to split the x16 in Think those Asus HYPER cards which plug into a x16 slot and create 4 x4 m.2 connectors, those don't have any bridge chip, they just split the x16 slot into 4x4 directly, the motherboards and cpu have to support it, and threadripper does... Here's the card https://www.asus.com/Motherboard-Accessory/HYPER-M-2-X16-CARD/overview/ and a video to see the insides. So I'm sure there would be some chinese people ready to replace the m.2 connectors with x1 connectors or x4 connectors to go to video cards. You get 3 x16 slots in your threadripper board and you get 12 x4 links to video cards, and you'll still have loads of lanes... use m.2 to pci-e adapters/risers, maybe board comes with slots that have lanes coming from chipset...
  8. Coins work against asics through two methods: either 1. requiring a lot of memory and a lot of memory bandwidth like ethash (ethereum), so making adding memory controller inside asic expensive and topping that up with cost of gddr5, making asic almost as expensive as video card. 2. making the algorithm really complex, lots of math, which means you need little memory but each hash takes a lot of computations so you would have to add a lot of transistors and other things in an ASIC, which increases the silicon area used by each chip (and you pay, like $10-20k for a manufactured 30cm disc of silicon from which chips are cut monero and cryptonight coins can be mines with only 2 mb of memory but they only do something like 150-500 hashes a second on a regular cpu (my fx 8320 does ~180-220 using 4 threads, because cpu has only 8MB l2 cache) and my rx570 does maybe 600-1000 hashes per second (i has 1100-ish but i don't remember if it was one or two cards installed in pc when i tested). In contrast, you get around 25 million hash with rx 570 or rx580. so if you make an asic for monero, yes, you're probably gonna make an asic that's a third or half as big physically than a cpu, but most likely it's gonna do only 50-100 hashes per second, less than a regular cpu. they could put lots of them in parallel like they do on bitcoin stuff where they have over 150 chips working in parallel, but like i said, it would cost them a lot of money to make the chips due to silicon size.
  9. Crossfire is no longer supported by AMD, in the sense that DirectX 12 has multi GPU support and game developers are supposed to be using that to spread their game engines across multiple video cards (ex use primary card for something, use second card for physics or whatever, or use parts of both for rendering frames) So basically with DirectX 12 or Vulkan you can basically install any second card and the games could in theory use those other cards. It is however something more difficult to do and something new, and it's not backwards supported in DX 11 and other versions.
  10. It's more like they're limited by the amount of HBM memory production, and the fact that they made contracts with Apple (their Apple Pro machines) and probably Intel to give them priority to the chips with HBM memory, so there's less quantity available for regular gaming cards (the Vega cards) And even if they'd have enough quantity, they'd be snatched quickly to be used for mining since they're great for mining Monero or whatnot.
  11. The way I know it, is that Ryzen 1 and these Ryzen with integrated graphics are made on the 14nm process. They planned to have Ryzen+ (Ryzen 1 with minor improvements, slightly higher frequencies, better memory support etc but same IPC and all that) made on 12nm process, a "revised" 14nm process. Ryzen 2 was supposed to be in a year or two, with more substantial improvements. Now, I don't know if AMD changed their minds and decided to call Ryzen 2 what was originally referred as Ryzen+.
  12. They're Ryzen 1 with tweaked memory controller (reduce latencies, some timings, more compatibility, higher maximum "official" frequencies). It's not Ryzen+ or Ryzen 2.
  13. Well, what I heard is that the Ryzen 3 2200g is sort of around slightly less than RX 550 or GT 1030 in performance, and the Ryzen 5 2400g is between RX 550 and RX 560 in performance, or a bit faster than GT 1030. Also worth pointing out that these are 65w TDP parts and they can be overclocked, both the cpu side AND the gpu side, and I think the leaked estimations were with 2667 Mhz DDR4 or something like that. For sure using 3000-3200 Mhz memory and overclocking the chip to get it within a 95w TDP will probably boost the graphics performance a bit.
  14. No, dude. 2500 kbps is 2500 thousands of bits per second. That's 2.5 megabits per second. There's 8 bits in a byte, so 2500 kbps is 2,500,000 bits per second is equal to 312,500 bytes per second, and from here you can either divide by 1000 or 1024 ... so you have either 312.5 KB/s and 0.3125 MB/s , or you have 305.17 KiB.s or 0.298 MiB/s His upload speed is 12.22 Mbps or megabits per second. That's 12,220,000 bits per second or 1,527,500 bytes per second.
  15. Not really. At that low bitrate combined with that fast preset, you'd probably get higher quality using the hardware encoder set on "slowest / highest quality" settings. With the hardware encoder, adjusting the quality settings doesn't affect the cpu, so you can do hardware encoding on "highest quality" at 60fps easily. x264 compresses so well when it can remove the duplicate information from consecutive frames and when it can sort of "blur" out edges and shapes in order to compress better - think of it like the jpeg compression where detail is lost the more you drop the percentage of quality. The more you change that quality preset from medium to fast or ultrafast, the you're reducing the amount of cpu time x264 has to make such decisions, so it will not do a lot of analyzing frames, won't look up in consecutive frames to only encode data once for several frames, and then you're further restricting it by setting a low bitrate. When it has only 2500 kbps to encode your video, that's 52 kbps or around 6 KB of data for every 1280x720 frame in your video, it's quite small, so because the codec has very little cpu time, it basically chops quality using some very quick and basic determinations. You can increase the bitrate and let it keep more detail in each image. The fast preset is also probably not optimum for your needs. If you have pixel games or games with very artsy graphics or cell shaded or cartoony games it may be worth to enable "animation" tweaks like changing the deblock settings, increasing bframes, reference frames And for example you could disable CABAC (less cpu usage for 10-30% more bitrate used) and use that cpu saved to increase the encoding quality... Lots of other things.
