7D25-017R is DDR5 and 7D25-012R is DDR4

The Eric Experiment on YouTube has a video where he tries PCI video cards on a Ryzen 9 3900X system. So for PCI video cards you don't necessarily even need a native PCI

Technically i7-3770 but it's not a big upgrade from the i7-2600

Sandy Bridge-E(P) has 40 PCIe 3.0 lanes. Though some older CPU steppings had problems with PCIe 3.0 on NVIDIA cards which is why NVIDIA drivers have PCIe 3.0 disabled by default on SB-E https://nvidia.custhelp.com/app/answers/detail/a_id/3135/~/geforce-gen3-support-on-x79-platform From what I've heard Radeons didn't have the problem and have PCIe 3.0 enabled by default. The Xeon E5-4650 you have only came in the newer stepping which had it fixed

Definitely RMA it. I don't think there's any point to even try to boot it

You should be able to get it to 3.0GHz just by bumping the BCLK to 333. I've had a Q6600 @ 3.0GHz BSEL (tape) modded in a Q45 based HP dc7900 SFF for years

On boards like that without VRM heatsinks it's best to use downdraft CPU cooler to get some airflow on the VRM. Have you checked what the VRM temps are under full CPU load (for example Cinebench R20/R23)? If it stays under 90C I wouldn't worry about it

That sounds like you have a faulty PSU, I don't see any other reason why it would trip with a 200W card. Even Dell themselves say the 635W PSU in the t3600 can handle 225W in the main slot and run a secondary 75W card at the same time. There's no way Dell would lie about the wattage in such a expensive professional workstation.

I'm pretty sure you don't need to update the BIOS for Windows 10 to work on the OptiPlex. Both of them are still decent systems for normal use if you have an SSD.

You can use The Retro Web to search which boards have the slots you need and then search them on eBay or something

I finally upgraded from the GTX 960 I've had since 2016 to a new to me GTX 1080 Strix Advanced. The difference in games is HUGE, games that barely ran on the GTX 960 at low settings now run just fine at much higher settings. Though the card might need new thermal paste, under load it runs the fans at close to 2500 RPM and the temps are around 82C with the case side panel open 3DMark Fire Strike. Ignore the CPU downgrade, I haven't put my better binned X5670 back in yet https://www.3dmark.com/compare/fs/29534986/fs/24012634 The card is thin enough to fit in with a USB 3.0 card below it. The gap is way bigger in real life than what it looks like in the picture

The x16 slot is connected to the CPU which does have PCIe 3.0 but the M.2 slot is connected to the chipset which is PCIe 2.0 only.

It's PCIe 2.0 since it's connected to the Z97 chipset which only has PCIe 2.0. And it probably only has 2 lanes since they advertise 10Gb speeds, and it was that way on Asus Z97 boards

The Xeon E3-1270 v3 is basically an i7-4770 but without the iGPU. The i7-4790 is clocked 100MHz higher but I doubt that makes much of a difference. Neither of them are great for a RTX 3070

Intel will probably try to compete with the really expensive Threadripper Pro platform since AMD doesn't have any consumer Threadrippers anymore. So if you need more PCIe lanes or more RAM and memory bandwidth than what the mainstream platforms offer you have to spend thousands for a CPU

It should work with pretty much any NVMe drive. You can get Clover from here: https://github.com/CloverHackyColor/CloverBootloader/releases And here is some tutorials: https://www.hamishmb.com/booting-nvme-older-pc-refind/ Or https://winraid.level1techs.com/t/guide-nvme-boot-without-modding-your-uefi-bios-clover-efi-bootloader-method/31665

This one at around 17:00

You can use Clover or rEFInd on a USB flash drive to boot from any NVMe SSD. Linus used Clover on one of the HP Z420 (which is X79 based) videos

Have you checked what CPU-Z says about it on the SPD tab? Normally RAM sticks have a part number which you can search on google to see if it's an actual stick. I have no idea what soldered memory shows up as on CPU-Z, but I'd expect it not to have a part number As an example here is what the tab looks like on my laptop:

Is your CPU overclocked and what's your monitor resolution and refresh rate? And what's your current card? Overclocked 3770K should be fine with a GTX 1660 Ti for less CPU heavy games but PUBG isn't one of those

That shouldn't be a BIOS issue because the 3930k is one of the CPU's the X79 platform launched with in November 2011. Both the 3 beeps and code 69 seem to be RAM related

When you got it to boot with two sticks, were they in single channel or dual channel? If it only boots with the sticks in one channel then the CPU might have something wrong with the other memory channel

Have you tried replacing the battery? A dead BIOS battery can sometimes cause some issue. You could also try reseating the RAM or try to boot it with only one stick in. Though I don't know why it would boot with the i7 but not with either of the Xeons. Have you had any stability issues with the i7 after it stopped working with the Xeon? It might also be worth asking on the Intel HEDT thread

That does look exactly the same as mine which has the design flaw

I thought the Elite 8200 was limited to 2nd gen (Sandy Bridge) CPUs, but if you already have a 3rd gen CPU then I guess you could upgrade it to the i7-3770. The i7-3770 is quite a bit faster than the i5-3570 thanks to HyperThreading. It also has a faster Intel HD 4000 iGPU instead of the HD 2500 in the i5. I wouldn't recommend spending more than ~25€ for one though
