Dell T7810 “Chia Farming” Workstation/Server, 2X Intel Xeon E5-2690 v4 up to 3.5GHz (28 Cores & 56 Threads Total), 128GB DDR4, Quadro K620 2GB Graphics Card, No HDD, No Operating System (Renewed)

Well, the Dell T7810 finally arrived! The tower was perfectly packaged in layers of bubble wrap to protect it from the long journey during shipping.I noticed some people who purchased one of these towers reported the tower was dead on arrival (DoA) and/or wouldn't boot to POST - blank/black screen. I also had the same issue of no POST (black screen) and believed it may have been due to the fact that I removed the unexpectedly installed 128GB SSD drive to install 3 1TB SSD drives. After some thought and a bit of research, I removed the CMOS battery, which when replaced, allowed me to access the BIOS settings (repeated pressing of F2 to access BIOS settings). After applying the default BIOS, setting the time, and a couple of other minor settings, I rebooted, and still the same issue - no POST and a blank screen.Long story short, I believe many people who reported DoA or no video issues may have the SATA Operation setting in BIOS set to use RAID instead of ATA or AHCI. Once I selected AHCI instead of RAID, I was able to install Windows 11 from a USB drive.It's a great system, and I'm very pleased. The tower was advertised as no hard drive or OS. I was surprised to see that the 128GB SSD, wired keyboard, and mouse were included. I very much recommend this seller!

Original purchased pc did not have the correct Ram or GPU, would not boot or display video, waited on an exchange, received the exchange and the second pc looked rough, super dusty, WRONG GPU AGAIN, and still WOULD NOT BOOT, was able to access the BIOS once but couldn’t ever get it to display again

Both CPU's are detected and the correct skuAll 128GB of ECC memory are detected and appear to be in the correct slots on the machine(showed up with 4 32GB dimms with 4 open slots)Booted up and is running proxmox flawlessly.Main things worth noting: there was a mouse, keyboard, VGA to DVI adapter, and USB wifi dongle but no power cable. I found that to be a bit unusual. Though I have plenty of those cables lying around so its wasn't the end of the world for me.I will update this review if there is anything else worth mentioning after a few months of use.

When the system first arrived, the case was really damaged and lopsided, seemed poorly packed. The memory had come off the system board, the power supply had come out, it was just a mess. I tried to power it on and it started to boot but the power supply sounded like a lawnmower. I requested a replacement, it was in much better shape, minor scratches was the only issue. I'm running Windows 10 and it runs really well. I've not found any application that will slow it down yet. I see the entire 128GB of memory and the CPU count, no issues there. For the price I'd go through the trouble of getting another if I needed it.

Workstation/Server delivered as represented with a nice caveat. A 128GB Samsung SSD was included with Windows 10 installed and license included. This was unexpected as T7810 was originally represented as without hard disks/storage included. Made the process of upgrading to Windows Server Standard 2022 that much simpler! Much thanks to the seller! Excellent value.Specs were spot on (again as represented in advertisement) with the only exception (not really impacting my needs) being the RealTek USB WiFi NIC (Wireless N) was too old for Windows Server 2022 driver recognition (didn't matter as I used Ethernet cable vs. wireless). Had I stayed with Windows 10 - would have been just fine.Documentation included had contact information for the seller in the event any issues arose (which none did for me). Good Customer Service and clear communication are always a component of a successful sale - we checked that box.So in summary, my purchase expectations were exceeded by getting more than expected within the timeframe, quality standard and customer service expected.Easy to recommend this seller for future Reconditioned Equipment Needs.

Added with HDD and NVMe SDDs (needed an extra Dell part for NVMe).Very easy to tranport on Trains and cars.Awesome and quiet sitting in my office and running simulations.

Workstation was clean and as described. Unfortunately it arrived unable to boot (obviously after putting in HDD). Dell reference guide amber blink pattern says RAM or CPU issue. I tried reseating and removing each stick of RAM individually, but still no fix. I assume it must be a CPU thing at that point. Maybe something shook too much during shipping? No idea. I am getting a replacement from this vendor, though, because I want this product. Will update this review once I hear from them.

Unit arrived well packaged and pretty clean with everything except the Quadro K620, it instead came with a AMD R5 340 that, although a very old model, appears to be a brand new unit / never used card. It also came with the 825W PSU instead of the 685W which was a nice bonus. Temps were running very hot, 50°C idle and hitting 100°C under light loads, so I ended up replacing the CPU coolers with the Noctua NH-U9DX i4 (https://www.amazon.com/dp/B00E1JGFA0) and some Artic MX-6 thermal paste. Temps are now down to 24°C idle. It should be noted that for this specific cooler, I had to flip the mounting brackets to the bottom of the CPU contact plate to make the mounting screws reach, and it also required a 5-pin to 4-pin fan converter but it is well worth it. If you choose to keep using the dell coolers, you will certainly need to replace the thermal paste. Other than that, all the RAM was present (mine came with 2x64GB sticks), the CPU was as described, and everything works as it should.
