    Good stories thread

    So to get the ball rolling. Lets see what you got.
  3. https://www.kotaku.com.au/2019/02/radeon-vii-amd-australian-price-release-date-specs/ AMD have revealed this afternoon that their new card, which will ship in multiple configurations with a baseline of 16GB in HBM2 memory, 3840 stream proessors, Freesync 2 HDR support and 1TB/s of memory bandwidth, will be available in Australia from $1069. It's also been publicly revealed that the Radeon 7 will run at a boost clock speed of 1800Mhz Availability on all cards in Australia and New Zealand is unknown, although the Radeon 7 launches internationally February 8 Australian time. We'll update this post once a local release date is confirmed. AMD Radeon VII Unboxing & Preview The main die on the "Vega 20" MCM is the centrally located GPU die built on TSMC's 7 nanometer silicon fabrication process. Measuring 331 mm², this silicon packs 13.26 billion transistors, which is a similar transistor count to NVIDIA's TU104 graphics processor. The "Vega 20" GPU die features a 4096-bit wide HBM2 memory interface, which has double the bus width of "Vega 10". This means the GPU has to be surrounded by four memory stacks instead of two. On the Radeon VII, there are four 32 Gbit (4 GB) stacks built on a 10 nm-class node supplied by either SK Hynix or Samsung. We don't know the process node of the interposer, but given it was 65 nm for 4096-bit "Fiji", we can't imagine why it would change for "Vega 20". The interposer has no logic of its own and draws no power for itself. Its only purpose is to provide miniaturized wiring between GPU and memory stacks, and as such, there's nothing to be gained by changing its fabrication process if the desired wiring density has been achieved. A metal-reinforcement brace runs the periphery of the fiberglass package substrate to distribute mounting pressure from the cooler. AMD has used conventional-looking thermal pads over the VRM MOSFETs, which are somewhat reusable. The GPU interface is a whole different story. Defying conventional logic, AMD went with what clearly feels like a high-conductivity thermal pad between the vapor-chamber base and GPU instead of thermal grease. We believe this to be a strip of Hitachi TC-HM03, a high-density thermal pad with graphite strands and a rated conductivity of 25-45 W/m·K, which is higher than the typically 12.5 W/m· K offered by certain diamond-based high-viscosity pastes. Going by the lengths they have gone with the cooling I am guessing they are once again pushing the clocks as hard as they can to try compete. That or 7nm just runs hot so it will be interesting to see if there is any overclocking head room left and just how much power it draws. Considering the RTX 2080 which will be priced similar only needs 6pin+8pin power vs 8+8 I think it is safe to assume that despite the 7nm process it will still be less efficient but then you do get twice as much memory.
  4. A bit of data somebody put together from others results. So it looks like they test what is a stable V then add almost 100mV more just to be sure. Edit: Some tests with the Radeon VII under a full cover block.
  5. Unfortunately the local metal work shop only has a plasma cutter which would warp the 2mm steel needed for a new mount plate and the closest laser cutter needed for making a new plate is 100k away and it will probably cost over half as much as the block itself just to draw it up on on the PC ready to be made. So I have run into a bit of a delay.
  6. The chance of increased radiation is probably enough for me to scrap the idea of a cheap china phone. Sister is talking me into Sony even though I am not a fan of the brand the XZ looks like good value for under $400 from Kogan or the premium can be had from a decent seller on ebay for a similar price..

  11. Yes the they have rushed out a few small fixes since the release driver this is 19.3.1 which was released yesterday. Timespy 8231 with AMD Radeon VII(1x) and Intel Core i7-6700K Processor Graphics Score 8886 http://www.3dmark.com/spy/6500306 Short test so GPU temp only hit 65c and 97c junction with fans topping out at 3000RPM at which they do make a bit of noise. 22-40% faster at stock than my 1070 on water with a powertune vmod and unstable. https://www.3dmark.com/compare/spy/6500306/spy/5308339 Safe to say it is a snug fit
  12. New card is installed here is a quick run at stock 20 844 with AMD Radeon VII(1x) and Intel Core i7-6700K Processor Graphics Score 28 464 http://www.3dmark.com/fs/18620818
  13. Looks like to get everything I want with Telstra\Optus rural reception approval I am looking at ~$550 for Samsung S8\+ and $50 for otterbox defender. Obviously there is other phones out there with good reception that they are not selling and thus haven't tested but it is hard to know which. fliptopia Thanks that is a whopper of a battery in a budget phone but looks like it is also lacking b28
  14. No heat pipes as the Heatsink has a vapor chamber over the core. That is just the edges of the HBM and the core seem to be a little higher than the center. Apparently there is a epoxy resin coating over the lot that is supposed to make it flat and protect the chips. Edit: I clicked post via startrack by mistake when ordering instead of express post so I paid $4 extra for something that will take a day longer as they dropped it in to the post office today to travel the last half the journey. But it could be worse as in the past they have just left items sitting in there local depot 100k away for over a week.
  15. Battery life is important especially when using GPS\Google Maps. General use with rural phone usage so reception quality is also of high importance with my S4 only just getting reception in parts of the house or outside and it was better than most phones for this. Otherwise nothing to intense some web browsing, listening to music and watching Netflix. Ah note 7 pro also lacks a 3.5mm audio jack so two strikes and its out. S4 was in a SEIDIO OBEX Case which was waterproof originally and saved it from many drops the final straw was falling out of my pocket on the motorbike we managed to find it and it rang once but that was it. So a tough phone around $300 is what I am after and a good camera would be nice although I don't give a crap about selfies. Some nice to haves would be USB C and a Infared blaster.
  16. Yes it would be very difficult and I probably wouldn't go so far as to have a step so the pressure on the HBM would be uneven . The block is nickle plated and I probably wouldn't go much past taking of the thickness of the plating. The hardest part would be holding it steady enough so that it only took of what I wanted even if I make some kind of basic guide. Here is the pressure tests gamersnexus did I will start with stock then move to water without lapping the block and later consider lapping it if temps are not good enough.
  17. Looks like My Samsung S4 may be toast although IO have ordered a new USB port to see if that allows me to root it and fix the corrupt files that prevent it detecting the sim card. What are your thoughts on the Xiaomi Redmi Note 7 Pro. Edit: Hmm may not support b28 700mhz
  18. Well it is in the mail. I have never been a fan of full cover blocks. Now I am wondering if I should lap my block so that it is slightly curved providing more pressure on the core and less over the hbm
  19. It seems the old TP-Link handle long range better while the new PLP2000 may be handling electrical interference from other devices in the house better. House to far end of first shed red signal quality about 50 meters. plp2000 to plp2000 =25Mbps tp-500 to tp-500 =37Mbps tp-500 to plp2000 =34Mbps Shed powerpoint with borderline red-amber signal quality about 40 meters. plp2000 x2 =30-37Mbps tp-500 x2 =50Mbps plp2000 to tp-500 =56Mbps From within the house green signal quality. Powerpoint A about 25 meters. plp2000 x2 =90-110Mbps <Green signal quality. tp-500 x2 =22-25Mbps <Bit of a roll reversal less of a range problem within the house but more signal interference from other devices I guess. plp2000 to tp-500 =58Mbps <Red signal quality. Powerpoint B This one is close to the power meter probably under 10 meters in total. plp2000 x2 =350-360Mbps tp-500 x2 =98Mbps Ok so now that I know the old TP-Link 500 are faster from the shed to the house I have three of the PLP2000 security linked separate to the two old ones Two PLP2000 for the security cameras in the sheds then a short patch cable running between the third PLP2000 into a TP-Link 500 back the the house. Now it is all working nicely but I do have to keep a bit of distance between the PLP2000 and the TP-Link 500 as it seems to lose connection if they share a power point so we will need a sparky to install some new points next to the breaker box, Probably one on the second shed breaker and the other directly into the power that comes from the house. As it turns out it would have been a lot cheaper to buy 4 slower EoP adapters than the PLP2000 since there speed advantage is lost over long distances I am tempted to try return them.
  20. Hmm thanks for the heads up just when I was tempted by ex mining 1080ti at about $650
  21. I think it will be worth it to me but time may tell if I'm right. Store doesn't open for a few more hours but the card is now completely removed from there website safe to say they got slammed with orders over the weekend. Ah well about what I expected.
  22. I think it is a fun challenge for overclockers but not without it's risks trying to get good core contact with fragile hbm in the way. Power use overlooked can go through the roof but it looks to scale fairly well with increased juice. Lower temp is bringing a nice performance boost even without overclocking or much change in power use which could mean good things for non reference coolers in the future.

  24. Ordered a MSI Radeon VII $1079 from Skycomp and I was wanting to play Resident evil 2 as well so hopefully I can claim that game bundle. But there not open on weekends so I wont know if I get allocated any of there stock or if somebody already beat me to it.
