    Indeed the Quadro M4000 isn't that power hungry (only 120 Watts TDP, which these days is considered as "pocket change" in terms of power use), but still considerably more than the Quadro NVS510's measly 35W TDP.

    Of course, since you aren't doing any gaming or serious rendering, I imagine that M4000 will be idlying most of them time... which means around 30-50W power use maybe. Whereas the NVS510 was probably running to at least 50% load due to those IP cameras, if not more... and very likely using 25-30W. Thus, the difference in power consumption likely won't be that much, indeed. But on the positive side, now you have a card with much more "headroom" than before (should you ever want to run, say, 2-3x more cameras than now. ) Either way, whatever you do, it's probably not a good idea to push that M4000 card to high loads. 120W TDP for a single-slot cooler solution... yeah, it's gonna run quite hot. Probably 80-90C at full tilt, and loud too. But for desktop use, it should be more than alright.

    Anyways, PC specs still look great. Has it really already been 7 years since you've built this? Gee, time flies! Well, here's to another 7 then:
    For what it's worth, the NVS510 didn't go to waste....my DVR needed a GPU, and this one is perfect. It doesn't strain a bit with all the IP camera feeds when only driving one monitor.

      Re: My Latest 8-core Project

      Well, it happened this morning....one of my 27" monitors shit the bed.... The panel went bad (common for the Dell 2709W), so no fix....it's been deteriorating for some time now. I saw this coming, and had a backup plan.....



      Say hello to 3x Dell u3011's, 2560x1600 16:10 monitors. I bargain hunted for a long time....I've got less than $400 in all these, screens are flawless. I was worried these would be too overwhelming for the desk....but after setting them up & tweaking, I should have done this long ago!

        Be careful - you might get some serious computer tan now!

        The monitor on the left looks barely on the edge of the desk, though.
        Next up: bigger desk upgrade?

        BTW, often there are quite a few really nice solid wood "executive office" desks for dirt cheap (sometimes even free) on my local CL, as there are a lot of gvmnt/admin offices in the area. If only you were closer.

          So they're cheap like those Sharp 70-inch'ers! You said "common", so I think it's safe to say bad like Sharp, not too long before Hisense bought their TV division, IIRC.

          It makes me sick to get word about that happening with a Dell computer monitor! I'm used to getting word at badcaps.net, about failures with TVs, OTOH. (the ones with a tuner) Or Core 2-era LCD monitors with bad caps.

          Except for bad CCFLs or the like, of course, for earlier LCDs.

            I got to my office this morning, fired this system up as usual....POST roll halted @ SAS init, saying a drive was missing from the 600gb RAID10 (4x 300gb Cheetah 15k RPM SAS).....sure enough, one had died. It boots just fine on the degraded array, I didn't have another HDD on hand to swap it out....so I'm runnin' on 3 at the moment....got another on the way....but redundancy saves the day!!

              Re: My Latest 8-core Project

              Curious to read more about the dead 300 GB Cheetah HDD. Is it clicking? Or just not recognized? I wonder if the Seagate server HDDs have the same problem with their head amp contacts oxidizing like the desktop lines do, and if there is a slim chance that might restore yours. I just cleaned and tinned the boards on 4 different Seagate models, ranging as old as the 7200.10 era and as new as the SV35 series. Unfortunately, that doesn't seem to have helped any of them, though. Half of those have bad sectors and click very unpleasantly once in a while, while the other two appear and read/write OK, but can't pass a thorough surface test. All high-hour count HDDs with low power cycle count. In my experience, Seagate HDDs like it the other way around: high power cycle count and low hours - at least the desktop models anyways. Seems after 20-40k POH, they start to act up.

                It's a 15k.5. It was making some weird whining noises, like it was only partially spun up to speed (maybe a bearing failed). It was not clicking. Controller showed it, but as 'failed'. I didn't even bother looking at the SMART data.

                  Speaking about HDDs, on Western Digital HDDs, I'm noticing what looks like a lot of corrosion!

                  Looks like corrosion, even on Blacks, too!

                    Low quality contact pads..... Remove the interface boards from the drives and take an eraser to the contact pads if they're corroding. Your HDD will thank you for it. WD is bad about this.

                      How the feck can I stop that corrosion? I saw that the corrosion is particularly bad, at least on Western Digital HDDs since circa-2010!

                      Then I looked at one of my Seagate Barracuda HDDs from roughly the same time and it looks like they hardly corrode, if at all!

                        I typically put a dab of non-conductive dielectric grease on them, it stops the corrosion dead. Do this for the motor & head interface on the underside of the PCB (it has to be removed from the drive).

                          Yup, anything made after the RoHS era is like that.
                          Seagate is not any better either, though.

                          +1 for the pencil eraser trick. I do that to clean the contacts first.

                          Either what TC suggested with the contact grease.
                          -OR-
                          If you are a solder monkey - coat the pads with leaded (Pb) solder. That's what I do all the time now. Just don't apply too much solder. It only needs a thin coating on there. Afterwards, clean with IPA to get rid of solder flux, as that can make the contacts non-conductive - obviously not what you'd want to happen.

                            IIRC some of the 7200.11 Seagates can be brought back from the dead with a USB serial adapter. I myself have made one from a Nokia USB cable (DKU-5) and have saved several Seagates.

                                Same type of failure on the HDD?? (bad bearing and HDD making excessive bearing noise??)

                                Curious what fails on these server-grade HDDs.

                                With the desktop models... particularly 7200.10, 11, 12, and anything onwards, it seems to be a combination of bad surface, head wear, and bearing wear. As stated previously, seems that desktop Seagate HDDs don't like high power-on hours. Power-cycle them daily when PC is not in use, and they tend to last a lot longer in terms of years (but not POH.)

                                Nice!
                                I like Hitachi HDDs. They seem to be pretty reliable for the most part. Only the older 500G 2.5" laptop models weren't so great. But apart from those, I have seen many Hitachi with 100k POH.

                                  This one just went dead. No spin-up, no communication with the interface (can't even read SMART data). At first, I thought the SAS port went until I tried the drive on a different port with the same result.

                                  With the desktop models... particularly 7200.10, 11, 12, and anything onwards, it seems to be a combination of bad surface, head wear, and bearing wear. As stated previously, seems that desktop Seagate HDDs don't like high power-on hours. Power-cycle them daily when PC is not in use, and they tend to last a lot longer in terms of years (but not POH.)
                                  I didn't check their POH hours when pulling them....but it's been 8yrs running 24/7/365 the first 6 years. About 2yrs ago I started shutting it off at night, so it runs ~10hrs/day now.

                                  I like Hitachi HDDs. They seem to be pretty reliable for the most part. Only the older 500G 2.5" laptop models weren't so great. But apart from those, I have seen many Hitachi with 100k POH.


                                  I'm happy with them so far. I got them for $11.00/drive, that's one nice thing about SAS...not many things support them....not a lot of demand. I run them in a RAID10, that's 600gb. Plenty of storage. I keep large storage on the NAS, so massive storage isn't needed on workstations.
