    What ya using your 1x slots for?

    USB expansion on an old server. Also, if you melt/carve out the little bit of the end of the slot so that longer cards fit, they run fine, just at reduced speed. I have a GT 710 in an x4 slot in a server running fine this way. For plain old video like desktop or even 4K video, data rate is...

    Are you upgrading your quad core in 2020?

    Wow, I'm really behind the curve. My main box is a 4570K with a OC to 4.9 and a GTX 680. It's been running like that for 7 years straight, 24/7. I don't have any real time to game anymore, so it's fine for most anything I do. My lab has three dual processor x5667 boxes, so 12 core / 24...

    3.2TB SSD for $240

    I have one in a R710. Works great and much faster than the SSD boot drive on SATA2. Had a weird issue this week where a power blip caused a reboot and the Fusion didn't come back up. Had to go in and re-attach the drive and reboot.

    Restoring a 486 machine

    If you do go the Win 95 route with a CF disk (highly recommended), be sure to turn off the page file or you'll wear out the CF fast. Voice of experience here. I might even have a ISA to CF adapter kicking around somewhere.

    Need an amp. New little one or a "vintage" receiver?

    I have an old Denon from 2003 that goes with my projector - it does a very competent job. I run it like GotNoRice above with the analog inputs. I generally run self-built tube amps for stereo duties, although my TV uses a little Tripath Class D 12w amp (it's on 24/7 because it's too much of a...

    Advice on Amplifier

    Them newfangled transistors? Bah. My current project uses 6GV8 / ECL85 / 6F5P tubes. OK, it uses several transisitors/MOSFETs as well, but they're hidden in the chassis. Only about 10-15 watts, but honestly that's more than enough. TPA3116 aren't too bad either. That's what I recommend...

    Advice on Amplifier

    Exactly 1500w. That's what class A means, constant power draw regardless of load. What isn't used for sound gets turned into heat. Also known as a space heater. It also is the maximum load for a standard 15 amp wall outlet. And only gives 3db more headroom than a 150w amp.

    Tech Jesus goes on a tear about size.

    For some reason that video popped in my feed the other day and I happened to watch it. Not for any reason other than I'm building a "workstation" from an old SuperMicro server board that's EATX. Fortunately, about a year ago I bought a 10+ year old case that I cut all the drive bays out of...

    Advice on Amplifier

    I don't think the OP is looking for THX levels from 20-20KHz. Based on other 2.5" drivers like in the OPs speakers, we get a 3db roll off between 125 and 250 Hz. I would assume that crossover and cabinet design would adjust that. Room size/design is also a huge factor, but I'm assuming this...

    He has a 100w sub so his sattelites only need to go above 100hz.

    Advice on Amplifier

    Usually it's better to have more amplifier power than the speakers are rated for to prevent clipping. But honestly, for computer speakers you're fine with almost anything. Looking at your speakers' 2.5" drivers, you're probably looking at low efficiency (~83 db/1w) and a low power handling...

    [H]OT Deal? DELL PowerEdge R610/R710 Servers sub $200? ($149-199)

    These are definitely an edge use case. My usage is for a SQL database that's highly RAM and iops dependent, so it's a good fit. Pros: Cheap Built like a tank, great reliability and redundancy (dual PSUs, 4 ethernet ports), enterprise level build quality Ability to put in lots o' memory (I...

    2nd hand stuff for home lab for latest ESXi (6.7 U3)

    As an update, esxi 6.5 or 6.7 aren't officially supported or tested (which is the responsibility of the vendors, who have no interest in testing old hardware), but I have heard that older Xeons do work with newer esxi versions. Might be worth some research if this is just for a cheap learning box.

    [H]OT Deal? DELL PowerEdge R610/R710 Servers sub $200? ($149-199)

    It's basically a big SSD that plugs into a x8 pcie slot, except you can't boot from it. Even though it's 7 years old, it's about as fast as a modern nvme drive except with about twice the iops. I use it to hold the db, as well as store ramdrive images (ramdrive is for the tempdb files and to...

    [H]OT Deal? DELL PowerEdge R610/R710 Servers sub $200? ($149-199)

    [H]OT Deal? DELL PowerEdge R610/R710 Servers sub $200? ($149-199)

    I bought a R710 a few months ago at an estate sale. Recently upgraded to 144GB of ram (18x8GB) for $100, $25 for a 240GB SSD boot drive, and another $40 for a pair of x5680 Xeons. Added in a 3.2TB FusionIO drive from the Hot Deals thread. It's pretty fast for a highly parallel workload, but...

    How much RAM you got?

    32 GB on my 7 year old i5-4670k everyday workstation. 144 GB on one of my SQL servers is the max, but I have 14 computers in my house. Older or single use ones (like a HTPC) have 4GB, daily drivers have 8GB, and a few like workstations or servers have 16-48.

    2nd hand stuff for home lab for latest ESXi (6.7 U3)

    I have two servers at home. Neither running esxi (anymore), but I have run it just fine on both initially. Both are dual socket 1366. One is a SuperMicro X8DTE board with dual hex-core Xeons and 48GB of RAM in a tower case using a consumer PSU and HSFs. Very quiet and office friendly. Cost...

    3.2TB SSD for $240

    They should work in an x4 slot (assuming it fits), but only be running at x4. They should work fine in a x16 slot as well. Heck, I've got a x16 video card that runs in an x8 slot in my server (Dell R710 if you want to look it up) at x8 speeds after cutting a gap in the end of the slot.

    3.2TB SSD for $240

    Got mine today. The seller is Save My Server (, a well known reseller of used server gear. Normally their prices are pretty good. Located in GA. Edit: Tested, and I'm getting CrystalDisk results in line with everyone else's. 87.74% remaining.

    Deep Cool 14.99 afmir

    It's a solid deal. I use the slightly smaller S40 on a pair of Xeon 5660 socket 1366 cpus in my server at home and they never get more than about 50 degrees C under 100% load.

    Need help fitting a HSF to a SuperMicro Xeon board.

    I know you already solved this, but for others in this scenario (like me), there's a simpler solution. The captive nuts on the bracket are M3. Just get some M3 screws about 2 inches long and install them from the underside of the motherboard. Use some M3 nuts instead of the included...

    Control box fan as case fan from Asus mbd plug

    This strikes me as an overall bad idea. If you don't know enough to ask questions with even somewhat appropriate terminology, you're probably in over your head and shouldn't be messing with lethal voltages. Now that the disclaimer is out of the way, there's two ways to do this. The first is...

    Fake fan tach signal?

    The PWM signal generators adjust the WIDTH of the signal (how much it's "on" vs "off"). The second one listed allows frequency adjustment, which is what you need. Run it off of 5v only and hook the output to the fan signal header. You may need to play with the settings to get the right...

    {HOT} AMAZON 20% Off For Prime Members!!!

    I just tried using the code(s). It gives a red text error that the code can't be applied, but then under the price and quantity of the item it adds a "$XX.XX discount applied" in a subtle red text. The difference is that is is only 15% instead of 20%. It also only worked on one of the...

    Samsung 4TB 850 EVO - $1499.99

    My standard server at work has only 8 drive slots. Two are RAID 1 for the OS. 5 are a RAID 5 array and the last one is a hot spare for either array. 5 drives in RAID 5 gives me about 15 TB of space with this. This is about right for the database I'm using. The price is actually good...

    Thrift store find thread.

    I found a matching set of three Dell 19" monitors for $10 each. Not great monitors (TN, about 8 years old, 1907FP models I think), but two of them fit well in portrait mode on either side of my 27" IPS and give me more room to work.

    Should You Hope Your Child Never Has To Drive A Car?

    I'm all for driverless cars. My 12 year old daughter has 20/200 vision and will never be able to safely operate a motor vehicle. Someone will either need to drive her everywhere or she'll be at the mercy of public transportation. A driverless car would be a huge quality of life improvement...

    Laptop Killing Booby-Trapped USB Drive

    Laptop Killing Booby-Trapped USB Drive
