    Zando_ got a reaction from Queen Chrysalis in Vega 56 only working with crappy PSU   
    Vega cards are known for massive transient spikes (giant wattage spikes for a couple milliseconds). Your nice unit probably isn't set up to account for these if it's an older design, so it trips OCP/OPP and shuts off the PSU. Lots of good units had this issue when the Vega cards released, no mark against their quality just the OCP/OPP settings had to be updated, and have been on all the newer refreshes. The crappy unit likely does not care and is just allowing the GPU to do whatever it wants.

    Zando_ reacted to Agall in To much water in my watercooling reduces cooling?   
    Well its not that water's temperature increasing affects pressure, it causes expansion and therefore the volume to increase. If the volume available is limited, aka, sealed without any lower density fluid to compress instead (like air at the top of a reservoir) then yes, pressure will increase due to the change in density.
     
    If a coolant is hitting 100C, then the CPU's temperature is well above 100C, likely past the point where the junctions in the transistors of the CPU die have broken down.
     
    You want some air for thermal expansion, otherwise a rise in temperature causes the fluid to expand and start compressing. There's a lot of things that can go wrong if you're increasing pressure, including how that affects the pump.

    Zando_ got a reaction from PDifolco in Worth it for $100 more?   
    The Nitro+ should be a better cooler and the stock clocks are slightly higher. If you don't wanna overclock yourself, and worry about temps a lot, then the $100 may be worth it to ya, otherwise not.

    Zando_ reacted to Aaron_T in Any recommendations for comfortable gaming chairs suitable for individuals over 300 lbs?   
    It's unfortunately a fair amount higher than your budget, but my Secret Labs Titan Evo XL has held up quite well for me. Had it for about 2-3 years. I'm 285lbs, 6'5". Not sure about QC on their latest chairs though. My daughter recently bought one and she loves it, but she's light, so not a good test.

    For known high quality, you could always go for a used Herman Miller. Their chairs are rated between 300 and 350lbs capacity.

    Zando_ got a reaction from GuiltySpark_ in Bought i9 13900F and im stuck at 2,0ghz.   
    Hmmm. CPU OC isn't supported on B-boards, RAM OC is though. It looks like it has the VRMs to run a 13900, and they have heatsinks so the VRMs shouldn't be overheating, so that won't be what's throttling the chip. What are you using to check clocks with? HWiNFO64 is the best monitoring tool, CPU-Z if you want to check just the current clocks, most other tools are occasionally inaccurate (especially Task Manager and HWMonitor, which I see lots of people use). What are you running that has it stuck at 2.0GHz, or does it just sit there no matter what load it's under or when it's at idle?

    Zando_ got a reaction from GuiltySpark_ in New pc rtx 4090, amd 7950x3d run cyberpunk with 20 fps   
    For fun? Because they're partnered with Nvidia and want to show off the tech? It's neat tech they wanted to play with and show off. It was never intended to be on for regular gameplay, and that's clearly communicated in the settings where the option exists. It was added after launch, alongside further optimizations to the game (when running without PT of course), so claiming it's a crutch for not wanting to optimize the game is really ignorant. 
     
    ^^^ I think it's fair to moan a bit about how hard RT can be to run, given it's clearly intended to run with it on. But PT is explicitly a "hey this is neat isn't it" thing, not a core graphics feature.

    I think there is some confusion with the games normal mode, RT mode, then on top of that the PT showcase mode. 
     
    You don't have to use the PT mode on your 3060 systems.

    If you want to look at it that way, sure. Its designed to be run in conjunction with DLSS and FG as a tech showcase and in combination, it works quite well. I don't think we're even close to the GPU power levels yet where native path tracing in a game that detailed is possible. Clearly.

    4K Path Tracing mode with no DLSS, Frame Gen or Ray Reconstruction?
     
    Yeah. 
     
    I did my last playthrough on a similar 7800x3D/4090 system at 4K ultra everything but with DLSS on Quality, Frame Gen and Ray Recon and saw in the 70-90's. Game looked incredible. 
     
    PT mode is no joke.

    RM's are newer, solid PSUs, should be as good or better than your TX. Fully modular too, so possibly a bit less cable clutter than your TX, depending on what cables you do or don't use.

    Zando_ reacted to mariushm in why isnt sata3 fully utilized even nowdays?   
    SATA uses 8:10 encoding, meaning for every 8 bits of data, there's 2 bits used for error checking and correction and other things.
    So out of those 6 gbps or 6000 mbps , the actual data that can be transmitted is 6000 / 10 * 8 = 600 * 8 = 4800 mbps or 600 MB/s

    Because data is further arranged in packets with headers and footers, realistically the maximum throughput (actual data read from or written to a sata device ) will be around 570 MB/s.

    Note that a sata controller may be limited by the connection to the system : for example a 2 port sata controller may be connected to the system through a single pci-e 3.0 lane, so while each sata port may do 550 MB+, in total the maximum connection to system will be less than around 950 MB/s. It works out if both sata ports are not used at maximum at same time.

    As another example, inside the chipset, the 6 port sata controller part may be connected to the rest of the chipset internally using 4 pci-e 2.0 lanes - so you get a total of 2 GB/s shared between 6 sata ports each capable of 550 MB/s

    M.2 uses pci-e lanes, each pci-e lane is capable of 250 MB / 500 MB / 985 MB / 1969 MB / 3938 MB (from pci-e 1.0 to pci-e 5.0)
    Versions 1 and 2 uses 8:10 encoding, from version 3 128 : 130 encoding is used, hence the weirder values.

    Zando_ reacted to ToboRobot in NAS or pay for backups?   
    from backblaze: "You may have heard of the 3-2-1 backup strategy. It means having at least three copies of your data, two local (on-site) but on different media (read: devices), and at least one copy off-site."
     
    I'd probably look at a small Synology with a USB external drive onsite and some sort of offsite backup.  But you don't need two services, so pick one.  And if you want you could self host the offsite data if you have a homelab or something.

    Or you can just have a bunch of drives, and keep some offsite.  You might not have a need to have all your backups quickly accessible as long as they are recoverable.

    Sliger Cerberus X. Closer to mATX size, but it fits EATX boards and multiple GPUs. Here's an example of one with two 3090s in it:

     
    If you want dual x16 GPU slots you'll need HEDT anyways, which usually comes in ATX boards at the smallest (given the massive socket sizes of modern platforms).
