You should always prefer longer AC-carrying cords to longer DC-carrying cords (like the ones coming from the wall warts). As long as you don't use a surge protector, a AC extension cord plugged into the UPS output is just fine as long as you pay attention to the power draw, as you are doing.

Hey Guys, quick question. My company has had a recent string of bad luck with Dell laptops. Basically one out of every 10 we purchase will BSOD and on reboot give a "hard drive not detected" error. It'll go away after a few more reboots but I'm sick of going through the rma process with Dell support. they have been doing this on every batch we order over the last year or so. I think its something to do with whoever they source their 256Gb M.2 drives from? not sure but it sucks. any other vendors you recommend? any I should avoid?

My company is a Dell shop. What model(s) of laptop are giving you this issue? I'd like to know in case any of mine are affected. Also, you might want to try asking in the laptop megathread.

How much should I care about a motherboard's VRM if I have no intention of overclocking? What is considered good/bad? What effect (if any) does it have on performance/longevity?

This is only because people otherwise tend to plug a kjillion things into a single outlet, overloading the capacity of the outlet or wires or the UPS. As long as you actually pay attention to how much load you add, it doesn't matter how you wire it up. (Just don't use garbage-tier hair-thin cables)

I just ordered a new laptop, a Portg X30-F1352 [Reference PUR33U-06500C], and am interested in swapping the stock keyboard out for a german one. IPC-Computer.de sells replacement DE keyboards for the Portege X30-E series, which looks like it would be compatible with the X30-F models. How much of a pain in the rear end would a job like this be? I've only messed around with swapping out laptop drives/memory/batteries before. Edit: Looking at this video of a different model, it seems like it would involve taking the mobo out. How bad could a patient adult actually gently caress that up? webcams for christ fucked around with this message at 21:43 on Jun 16, 2020 |

It's kind of crazy seeing people talk about the mSATA drives in Dell laptops go bad, I just had one die on me a month ago (in a Latitude, forget the exact model #) and it seemed a little fishy for how new it was (computer was 4 years old, I had it refurbed for about 1 year so it's somewhere in that time frame). Are mSATA drives more likely to fail then regular SSDs?

I asked this in the VR thread but I kinda wanted to get any other opinions on it. Right now I have an i7 8700k running a 1080Ti and 16gigs of ram. Is it really worth it to bump that up to 32gigs? Ram doesn't seem terribly expensive but if I'm really not going to get anything out of it I'm not sure I'd do it. Anyone have any thoughts on this?

What effect (if any) does it have on performance/longevity? if you're not trying to overclock, then it's probably not going to matter all that much, because the motherboard is just going to ease off the gas if it's getting too hot there are maybe edge cases where trying to pair a 16-core Ryzen processor with an A320 motherboard is not great because even if the motherboard/CPU is never going to run at a pace which will be a problem for the VRMs, it might mean that you're leaving some performance on the table, but it's difficult to come up with a recommendation without getting into specifics in any case, anyone who is going to buy a 16-core Ryzen probably also has a particular use-case where an A320 is not going to be sufficient for their needs in terms of SATA ports and PCI-e slots and rear I/O and all of that stuff, so they're also probably going to buy one of the higher-end enthusiast boards anyway, just so that they can mount their five hard drives and their video capture card and their six peripherals, even if they're not going to specifically use the overclocking functionality so I would think about THAT first, and if you still find yourself in a position where the basic H310 motherboard looks like it's good enough for you, but you still think you might pair it with an i9-9900, then you can ask

Don't be alarmed if you're constantly at 80%+ RAM usage, your computer will try and use as much RAM as you have because what's the point of keeping that empty and leaving things on disk? As long as you aren't paging to disk, you're fine.

I just brought my RAM up to 24 gigs on a machine running Windows 7 Home edition, but found out that particular OS will only support 16 gigs RAM maximum. I COULD just upgrade Windows, but had just read about RAM hard drives. As a workaround, could I create a RAM hard drive out of the extra 8 gigs, and designate that as virtual memory? Would it have the same effect as just using the extra RAM?

It may help a bit if you do end up paging to disk but bear in mind that extra RAM does nothing unless you need it. It's not like processor speed or RAM speed where more is almost always better, it will do nothing until you fill it up. I kind of have to ask though, if you've got a machine that regularly goes over 16GB of RAM usage why is it still on Windows 7, and home edition worst of all? It's probably time to upgrade it to Windows 10.

Computer audio question: I'm up to three separate computers at my desk now and use (bog standard 3.5mm stereo jack style) audio from each of them for different things. Would like to stop fiddling between those three inputs and two outputs (headphones and desk speakers) and just plug all five cables into one box, ideally having the sound mixed (eg hear alerts from one source on top of music from another) but I'd accept switching if I had to. Mildly perplexed that nobody seems to sell something sitting in between "KVM switch with computer audio" (already have a regular USB switch, plus those things' audio is usually awful) and "bona fide audio mixer like what Rolls sells, and audio nerds hate 3.5mm jacks so have fun with a pile of adapter dongles". Am I missing some product line here or am I doomed to choose between these three worlds (manual fiddling, poor audio switchery, or overpay and overdongle)?

(I was holding on to Windows 7 for the sake of my girlfriend, who uses it too and is kind slow to learn new computer stuff.)

You should upgrade because Windows 7 is no longer getting any security updates. Unless you love having your PC taken over, it's time to let go.

Amusingly I had found the MX42 and MX51S but not the MX41B, so thanks for digging it and its 1/8" jacks up. It and the MX42 will have the same possibility of volume shenanigans as the Rockstar, but they also have knobs to futz with to possibly counteract.

I plan on buying a Macbook soon, and I just want to know where to buy an actual, not-bullshit, USB-c/TB3 to HDMI 2/2.1 cable that supports 4k60p in Canada. Amazon is just so full of conflicting reviews/broken english in product descriptions, and fly by night "brands" that it's nigh impossible to know what's good and what's poo poo. Preferably an actual cable, and not an adapter, just so I don't have to buy two things. Length doesn't matter.

what's the current easiest/best way to diagnose what could be going wrong on a computer? is there a utility that'll stress test the whole thing and spit out the data and identify issues? I'm a heavy chrome user and it used to always be fine, but lately (mainly using google chat or browsing really long email threads) the computer will begin to grind to a halt. I'm wondering if it's my RAM that is starting to fail or my GPU, or if it's something else (throttling?), but it has been a while since i've done any diagnostics on my machine... so i'm out of practice and out of the loop!

if you still have a working computer, I would recommend getting HWMonitor to check temperatures, and windows task manager to see what's chugging if you're running out of RAM, you should be able to see it if something is maxing-out your CPU or GPU utilization, you should be able to see it if very high temperatures are causing your CPU or GPU to throttle, you should be able to see it

I had an mSATA drive die on me about a month back, and after unsuccesfully trying a new adapter, wrote off my losses and figured it's probably dead (I know that solid state memory tends to just plain die, it's not like a spinny that usually gives you warning signs and has several degrees of failing before stuff is unrecoverable.) But I was browsing YouTube today, and heard someone offhandedly reference "reballing" an SSD by heating it up. Is it legitimate, or is it just weird placebo effect nonsense? If anyone has done it and could share any particular tips it would be really helpful, I have a heat gun as well so no need to contaminate my toaster oven. I also figure since it's currently dead, if this doesn't work it's not like I'll make it more dead ya know.

I have a coworker who is buying an i9-9900K, and he needs a cooler. He's interested in my H55i (a 120mm AIO), but I don't want to sell something that provides insufficient cooling. If he doesn't plan on overclocking, would that be fine? I assume since it cooled my 2070 Super just fine but I figured I'd double check

I have an h115i pro (280mm rad) on my 9900k and it's fine. The issue is more getting the heat across the spreader into the fluid, I think the h55i would be alright if he's not trying to OC like crazy. Should be benchmarks out there.

I had a GPU with a 120mm AIO on it which handled ~180w just fine and kept the GPU temps below 60C, a 9900k worst case AVX stock is about that much power so it will be fine. The thermal bottleneck on a 9900k is pretty much the die itself which is unusually thick compared to previous generations (probably to help it deal with the mechanical stresses caused by rapid thermal cycles).

The only applications where I think you'd notice performance loss from a 120mm AIO getting soaked from heat would be code compiling and over 144hz gaming. If he's super duper interested in big numbers in those aspects he might want a 240 or 280 but otherwise he'll be fine.
