Can You Put an RTX 4080 in a Dell Workstation? (Precision T7865)

Dell Precision 7865 Upgrades - ScottDotDot Cover Image

I just got my most expensive single computer ever. It’s an already-outdated Precision 7865 with an AMD Ryzen Threadripper Pro 64-core CPU, direct from Dell. RAM upgrades from the manufacturer are always a bit of a rip, so in this video I upgrade it to 512GB. Also, I find out for the first time whether a consumer graphics card (PNY / NVIDIA RTX 4080 16GB) will actually fit inside the moderately-sized chassis. Oh, and fit two Western Digital Black SN850X 4TB SSDs to replace the woeful 256GB el cheapo card that came with the system from Dell. Absolutely nothing in this is a paid ad. It was paid for by my wallet. Buy Dell, HP, Asus, even Razer for all … Continue reading

Reducing Fan Noise from a Dell PowerEdge R905

If you’ve read my blog, you know that I have a quite a few servers in my basement that I use as a home lab environment. For home or low-demand virtualization, you can’t beat the Dell R905 for price. Consider that, as of the time I’m writing this post, you can get an R905 like I did with 128 GB of RAM for about $960. That’s only a little more than the cost of the RAM! That machine has 4x AMD Opteron 8356 quad-core CPUs @ 2.3Ghz and two built-in 10gbps ethernet ports (plus 2 gigabit ports), a PERC6i controller, dual PSUs, and a full enterprise DRAC. It’s a little old, but you can’t get those specs in any other … Continue reading

Quieting Dell PowerEdge 1855/1955 Blade System Chassis Fan Noise: Undocumented DRAC/MC Commands


TL;DR: Skip right to the undocumented commands Background I recently purchased a Dell BMX blade chassis on eBay that came loaded with ten 2x dual-core, 24GB PE1955 blades.   For a system with 40 cores, 240 GB of RAM and two 16-port gigabit switches in a 7U frame, $2500 was too good to pass up.  Especially since shipping cost me a mere 2 hour round-trip to Brooklyn. I didn’t really need ten more servers, so I figured I’d sell off 5 or 6 of them (hopefully breaking even on the entire system — the 4GB FB-DIMMs in 6 of the servers is worth $1450 – $1900 alone).  The remaining servers would be all mine! But I forgot to research the noise!  … Continue reading
