    Strange price spike on older Samsung EVO microSD cards

    Can anyone explain this? Why is the price of Samsung's older (green) MicroSD cards 5x the price of newer (blue) cards? What don't I know? Maybe the old one is TLC and the new one QLC? It's not just amazon, I'm seeing this all over.

    How do graphics adapters order multiple displays??

    I'm running into weird display ordering. Can someone explain what this thing wants from me? I have an old dell laptop, two 2x monitor setups, and identical dell docking stations. The existing one is wired 2x DP->DVI, and output 1 is always the left, primary display. I set up a second dock...

    What's the deal with Honeywell PTM-7950 paste? Scam / Legit?

    I've been seeing posts about Honeywell PTM-7950 (or -7958) phase-change thermal paste, mainly on reddit. They say it's the bees' knees, and also only available from one website in china with questionable reputation. I see no mention of it on [H]. If it is what they say, its performance...

    What idle wattage should I expect from a new system?

    In my long experience with computers, all desktops seem to settle at around 60watts at idle. Has this changed? I'm trying to build a new file server from newer old parts and am surprised that like the previous two, they also idle at 60-ish watts. So if I were to get a totally new...

    Torguard VPN client will consume 50% CPU when you're not looking

    I know that's quite an accusation but listen to how weird this is. I don't know if malware got into their code or they're running some revenue generating resource theft thing, or what. So I've been using Torguard for a while. Recently (in the last major version) I find my computers spinning...

    Why would a non-active GPU be showing activity?

    I have a laptop (Dell precision 3510). Normally I used the integrated Intell HD530 video. However, in GPU-z I often see activity on the discrete Radeon R9 M360. It's not all the time - sometimes it's some constant nominal amount. But here it is using the GPU and increasing the GPU temp...

    new Samsung 980 Pro reported as SSD 980 - what gives??

    I'm trying to upgrade my precision 3510 laptop to use a Samsung 980 PRO M.2 ssd in win10. It works, and win10 installs on it. However: Both Device Manager and Samsung Magician report this as the lower-end 980 SSD model (no DRAM) Magician also reports a compatibility problem: "The device is...

    So I may have gotten an unwanted crypto miner

    My foray into crypto may have had an unwanted consequence. I'm seeing high levels of GPU load when not running any miner. I'm asking you guys because of your knowledge of miners, but also of GPU behavior. This is a laptop and I'm only ever using the HD530 integrated video. The Radeon R360...

    What's an ideal windows antivirus to use when mining?

    New to mining. Dealing with anti-malware mechanisms is a big nuisance, not to mention having to evaluate each potential threat. I generally run avast on windows but the exclusion mechanism is unusable for this. What should I use instead? And what's a good way to know that a given miner...

    What can I mine with a Geforce 760?

    I have an old Gefore 760 card (2gb) and have been attempting to set up miners on it. I haven't had any luck so far. I do have my 1060 running with various nicehash versions. The nicehash apps I've run claim that there are no supported cards. From their docs, they require a card with Nvidia...

    Quick advice on quieter CPU fan?

    I have a Cooler Master Hyper 212 (evo?) adn it's running a little loud. I think it's a problem with my old computer (AMD Ph2 X6 AM3) and the thermal management in Win10 (or simply because it's tweaked), so the fan runs a lot faster than it should. I think this mobo is so old that it doesn't...

    Noob question: Ballpark revenue? $0.70 per day on a 1060?

    I basically wanted a space heater that pays me back during the winter, so I spent all afternoon learning about mining. I set up NiceHashOS on a machine with a geforce 1060. It should be about 20mh/s. Nicehash's dashboard tells me [at best]: Current mining profitability 0.00002304 BTC / 24h...

    Laptop memory upgrade questions (ddr4 32gb->64gb)

    I'm looking to upgrade my dell precision 3510's ram from 32gb to 64gb. The cheapest I can find is about $200 for 64gb, but I'm not sure of compatibility and performance impact. Current memory (factory) : 2x16gb 2133mhz DDR4 , CAS 15 Some options (doesn't need to be this brand at all, just...

    Why are there no ads on hardforum?

    I just realized that I never see ads on hardforum. I have nothing blocking them, and years ago I recall that being an issue. Should I be seeing ads now?

    Does this exist? dual-link DVI ----> displayport adapter

    There's plenty of Displayport to dual-link DVI adapters out there that let you connect a dual-link DVI monitor to a PC's Displayport output . But do any exist the other way, where you have a dual-link DVI source, and wish to connect to a Displayport monitor's input? Are there any adapters that...

    GPT/MBR considerations migrating data from older computers

    I have an old file server that I want to migrate data from. This is literally a 486 on an intel board with windows server 2001. The data is on a single constellation 2tb drive which ran 24x7 for at least 6 years, with very light workload. It hasn't been used regularly in about 4 years. I...

    HDD "locking" as a means for isolated multi-boot

    Can you use HDD Passwords (or DriveLock, or equivalent) to securely multi-boot? That is, if two hard drives are installed with HDD passwords, can the BIOS select between these and prevent access to the drive that wasn't unlocked? So if I have: HDD A: windows HDD B: linux Can I start the...

    Effect of orientation of antennas and antenna arrays?

    If you have a long, straight antenna, afaik, the best transmission and reception will be in the plane perpendicular that antenna (and also bisecting the antenna). So if your router has orientable antennas, and a single-story house, you'd want to place it near the center of your house and orient...

    VirtualBox - Enabling encryption allocates all dynamic storage

    So, if I create VM with 50gb dynamic drives, and only use 20gb, why does enabling encryption permenantly expand the .VHD file to 50gb? This is a win10 guest on win10 host. So, even if I decrypt the VDI file, it stays at 50gb. If I compact the file, it still stays at 50gb. Any ideas?

    Are there any cheap Wifi6/AX routers or access points?

    These new AX routers are jammed with features and super expensive. But I think I need the speed and selectivity, because wifi in the city with 10+ devices per unit is getting super crowded. I can only get 26mbits through wifi at best with any of my three 802.11n router/aps. To cut costs, I...

    Enterprise drive in a home file server - advice? noise, reliability, etc

    I'm looking at building a new home file server. It needs to be reliable, efficient and quiet. And not too expensiive. I don't think RAID makes sense for me, so it's going to be a single drive. My existing server uses a single Seagate Constellation (es.2 or .3) which has been rock solid for...

    Good free backup options? Need advice

    Hi - I'm looking for recommendations and advice for backup software. I used to use Ghost and Drive Image from bootable CD to USB drive for decades, but I'm not sure those are going to work anymore. I actually bought Drive Image, didn't receive the rebate, then lost the media and I'm all...

    16gb upgrade on old Asus M4A785-M

    I have an Asus M4A785-M which is AM3 with DDR2. I recently tried to upgrade its memory from 8gb to 16gb and am running into problems with various memory testers (eg memtest86+). Maybe some of you hardware grandpas have some wisdom to share. The configuration is just the mobo, phenom II 960T...

    Help with M.2 SSD keying

    Hi - I'm new to m.2 drives, and want to make sure I'm getting the keying right. Do some sockets mount the SSD card upside-down, where the label faces down? Is this adapter an m-key socket? Note the side the key is on, and both msata + ngff in the description...
