I have a WD Red hard drive that is approaching three years of use. I use it to store media, downloads, and the occasional big game (looking at you Warzone).What's the recommended program to check the health status of the hard drive?

Also, I wanted to start using Nvidia shadowplay with this hard drive instead of on my SSD. I was also wondering if the constant writing from game recording would significantly increase the chance of failure of the HD. If it's minimal risk than that is fine.

Constant paranoia. Crystal DiskInfo will give you it's S.M.A.R.T. data which will let you know if it's detecting problems, but drives are perfectly capable of failing without reporting any S.M.A.R.T. issues. 3 years isn't long enough I'd be concerned, but anything important should be backed up from day 1.

I noticed that HWinfo64 gives a drive 'life' % that you could maybe use in a broad strokes sense. Although my WD Red doesn't give that value, at least there is a drive warning box. Take a look:



Shadowplay on your HDD shouldn't really impact the drive (I don't think) compared to something like a raid array where it's constantly being rewritten on. I do wonder though about a WD Red drive not being allowed to idle or w/e, I think it has features that make it optimized for chilling out. I assume you mean shadowplay where it's constantly recording the last x min? You could always have that temp file on the SSD and then have it write to the HDD (I think).

You're correct on it constantly recording the last x minute. I'm not too worried about the HDD not being idle because it only records when playing games. But looking at drive remaining life on my SSDs, I might as well just put a temp file on a SSD.

I have a Monoprice dual-monitor gas spring setup right now with two 24" monitors. You've seen them before, it's this one:



I want to upgrade one of the monitors to a 30" which weighs 16.20lbs. The specs say the stand can only support monitors that weight up to 14.3lbs.

Will I likely be ok even though I'm about 2 pounds over the max weight, or am I going to need a new stand?

I don't know for sure, but I'd probably try it in case the monitor's weight includes the stand or power supply or something.

I'm in the market for a new monitor, and I'm noticing that you can pick up a 24-inch monitor for 1920x1080, and then it goes all the way up to a 32-inch that's still advertised as a 1920x1080.

I understand that with the better monitors comes higher refresh rates, and support for adaptive sync, and the difference in bezels and maybe if the panel is curved, but if I'm fine with a 60 Hz screen and none of the gaming bells and whistles, what's the difference with getting a larger monitor if the resolution is going to be the same? The bigger monitor, at the same resolution, will look like it has larger text?

I know this isnt the exact right thread but I tend to post tangentially related questions in threads where I actually know some of the posters soo;

do i need to worry about signal "loss" or whatever for a 3.5 aux cable being extended by 20 feet?

also, what could i be looking at to easily manage switching my headset from being used on one computer to the other? so, basically, headset+mic combo <<< splitter <<< PC1 + PC2(W extenders). if such a thing exists with the ability to switch USB periphs too thatd be worth considering as well

im basically running cables to be able to use one computer in two different rooms. so far its working perfectly and i think that would be the final piece

Iíve noticed that the power saver power profile on my desktop brings the CPU temps down by like 6-15C (from 45-55C to <40) and keeps things extremely quiet. It also basically never bounces around, it just stays at a stable like 38C. I have a Ryzen 3600/AMD 5700XT build. Hyper 212 cooler.

I havenít really noticed any issues with performance during office tasks in this profile and I ran Cinebench and it gave me a score of 3415. With the Ryzen Balanced plan I got 3650. Is that ~7% performance hit really the whole compromise of power saving? Is there anything wrong with running in power saving all the time except when I play games?

Is there any way to fully automate the switch? I made a couple of autohotkey scripts to switch between the two modes, is there any way to have it identify a given set of programs as a game and switch to the balanced/high performance profile?

Your fan profile is probably set up too aggressively, as is the default with most mainboards if your CPU cooler isn't quiet in Balanced.

Trying to put together a new build:

* I seated two memory sticks into the motherboard slots
* I seated the Athlon 200GE CPU into the socket. I knew the CPU was working as recently as July of this year
* I put some alcohol on the IHS, waited a few minutes, then wiped-off the dried thermal paste with a kitchen towel
* I took the basic AMD box cooler and did the same procedure on the business-end to remove the dried thermal paste on that one
* I applied some new thermal paste, mounted the cooler, and plugged the cooler into the motherboard's fan header
* I went over to the case, and mounted the PSU and the I/O shield
* I screwed the motherboard onto the case's standoffs
* I plugged-in the 24-pin power connector, and the 4-pin power connector
* I plugged in just the two pins for the case's power switch
* I plugged in the PSU into the wall
* I plugged in a monitor and a keyboard

I press the power button, and nothing happens

I violated my own best-practice by not bench-testing the motherboard outside of the case first, so I take the motherboard out of the case, and try to run it just resting on top of the motherboard's cardboard box. I figure this might be a way to isolate if there's some kind of short between the motherboard and the case. Nothing happens.

I use an external power switch to isolate if it's the (brand-new) case's power switch that's the problem. Nothing happens.

I use a PSU tester to verify that the PSU works, and it does. I even already know this because I was using the PSU back in July

I've never tested the memory before, but I figure that if it was bad memory I should at least see the CPU fan start spinning, or that I should get a POST

The problem has got to be the motherboard, right? I've got a few more things I could try, but since I already knew the PSU was good, and I already knew the CPU was good, and if it was bad memory I should have gotten SOMETHING to happen, and I don't want to throw another couple hours into troubleshooting this thing if I've already done my due diligence.

I guess my other question is, could I have killed the motherboard myself due to bad handling?

* I didn't test outside the case first
* the I/O shield was fitted badly. I had to take it off after I realized I couldn't plug into the HDMI port with it on because it was so out-of-alignment. Could the bad alignment, or not having it on at all, have caused a short?
* the power cord I was using for the PSU had the third prong for ground removed. In retrospect that was real dumb, especially since I had a spare with all three prongs, but I could've sworn I was using the same cord when I was tinkering with a build in July

Is the RAM on the mobo QVL? Can you test with other ram? Have you tried using just 1 stick and moving it between slots to see if it works? Not having ground for your PSU is insane. Are you using the grounded cable now?

Sounds like a bad motherboard, but there's no way to tell if you did it or it came that way, really. I'd do a CMOS erase just to be sure and try different ram slots but I've had stuff get hung up on ram problems and the cpu fan still spun, it just wouldn't go any further. Unfortunately these days it seems like stuff often arrives DOA.

The only draw of PCIe 4.0 right now is more lanes rather than faster speed.PCIe 4.0 storage devices will be somewhat expensive, and it remains to be seen how much companies will capitalize on it. It's not even supported by Intel yet.

Saves you from the scourge of motherboard fans and oversized heat shields.

Features like DirectStorage and RTX IO are more about better compression-decompression of assets, and who's to say how much PCIe 4.0 speeds will even be utilized by games when PCIe 3.0 SSDs will be the bottleneck for devs anyway.

Saving money now instead of spending something that will become relevant at some point in the future isn't the worst way to spend your money. Ask yourself when you are even likely to upgrade your storage anyway, too.

Rolo
Nov 16, 2005

Hmm, what have we here?

Thatís kind of my spending mentality but Iím pretty shaky on gen 3-4 differences and tech Jesus still goes over my head a little bit while Iíve been catching up.

My Samsung Evo m.2 SSD is absolutely great at the moment and has plenty of life left, Iím not planning on upgrading that to 4.0 anytime soon. The b550 (if Iím understanding correctly) also already supports the 4.0 capabilities of my 3080, so all Iím giving up are 4.0 cpu lanes that my processor supports.

I wasnít sure if that performance drop (if there is one) is worth the trade-offs that my current motherboard is silent without the extra cooling and also is already installed.

If itís not a ďno stupid why did you get that motherboardĒ easy decision Iíll probably just chill with it and my money.

There is no - current - performance impact of PCIe 4.0 for the 30 series that I'm aware of. It just supports it because it might as well.

Here are some straightforward benchmarks: https://www.kitguru.net/components/...analysis/all/1/

Here is an official quote by Nvidia: https://old.reddit.com/r/nvidia/com...ed_we_answered/

quote:

System performance is impacted by many factors and the impact varies between applications. The impact is typically less than a few percent going from a x16 PCIE 4.0 to x16 PCIE 3.0. CPU selection often has a larger impact on performance.We look forward to new platforms that can fully take advantage of Gen4 capabilities for potential performance increases.

I'd get PCIe 4.0 just because - and because I take like ten years to do a full upgrade - especially as adding new M.2 drives gobbles up PCI lanes, but I also don't know what the price difference is. Motherboards can be pretty expensive.

Pros and cons and all, but for the purpose of gaming performance, as long as you don't take up too many PCI lanes from your GPU, you're probably fine.

The big question is DirectStorage and how it uses and requires PCIe 4.0, I don't have the expertise to give you something certain about that: https://www.rockpapershotgun.com/20...ctstorage-tech/. But again, everything costs money, and is it a bigger performance bottleneck than something else you could spend money on to upgrade like, say, better cooling.

Going by the article, even Microsoft can't tell us if we need PCIe 4.0 for it.

College Slice

There's no reason to think DirectStorage will require PCIe 4.0, it's using features of the NVMe protocol which long pre-date 4.0 but just haven't been exposed on consumer platforms until now. It'll take advantage of 4.0 speeds if they're there but it's extremely unlikely that cross-platform games will actually expect those speeds this gen, given the Xbox only has PCIe 3.0 speeds (technically it uses 4.0 but only over 2 lanes so it's equal to 3.0x4).

There's a significant price premium for 4.0 drives at the moment so I wouldn't bother unless you're doing a build.

One of the PCIe slots, and one of the M.2 slots on a B550 board do support PCIe v.4, namely the ones directly connected to the CPU. The only significant difference between a B550 and x570 board is that you won't have PCIe v.4 slots coming off the chipset. Which model do you have?

As long as you don't stick your GPU in the secondary PCIe slot, your 3080 and your CPU speak PCIe v.4 with each other already.

The top PCIe slot and the top M.2 slot are both PCIe v.4, so you didn't mess up in any way. If PCIe v. 4 becomes essential for performance in the future, just leave the top M.2. slot free for a v.4 drive.

B550 is a great choice for a microATX board, actually, since X570 is a bit overkill in terms of making room for everything on the board. For an EATX board, X570 makes more sense. The only possible disadvantage I can see is if you were planning on running bridge-less dual-GPU, in which case PCIe v.4 on both PCIe slots might be an advantage, but that is a very weirdly specific application which few games support.

Rolo

This is starting to make more sense. Iím trying to understand the mapping of lanes with respect to the CPU, GPU, storage and motherboard chipset.

It sounds like:

If I only care about the speed for the top m.2 and top PCIe slot (which is the case) that Iím totally 4.0 compatible and that I would only be bound strictly to 3.0 lanes if I wanted to expand further, which would require a 4.0 connection between the cpu and motherboard chipset, something Iíd get with an x570 but donít currently need.

Am I getting closer?

It seems to have everything Iíll need for a decent savings compared to a B550. Iíd probably pair it with a 3600 for what itís worth.

This is starting to make more sense. I’m trying to understand the mapping of lanes with respect to the CPU, GPU, storage and motherboard chipset.

It sounds like:

If I only care about the speed for the top m.2 and top PCIe slot (which is the case) that I’m totally 4.0 compatible and that I would only be bound strictly to 3.0 lanes if I wanted to expand further, which would require a 4.0 connection between the cpu and motherboard chipset, something I’d get with an x570 but don’t currently need.

Am I getting closer?

Let me make it simple. Don't worry about PCIE 4.0 AT ALL. In a few years it'll matter, and even then it'll be more about board topology and getting performance out of fewer lanes.

Hmm, what have we here?

I was just more or less curious at this point but I think I got it now. This diagram seems to back up my vague understanding of what the lanes between the cpu and chipset are used for.



I appreciate the explanations, Vir.

Does it tickle when your Body Thetans flap their wings, eh Beatrice?


You're welcome. That sort of block diagram does belong in the motherboard manual too, but it's not always included.

Yes there are acceptable ITX A520 boards, because you can even turn on memory overclocking (XMP/D.O.C.P.) on A520 boards, and you only lose manual CPU overclocking which does nothing practical on Zen 2 CPUs anyway. That board even has a PCIe v.4 M.2 slot. The PCIe slot is v3 but as discussed earlier v4 isn't really necessary at the moment. v.4 will really come to its own when it comes to pushing more data through an x1 or x4 slot, but as that board only has an x16 slot anyway,.
