1366 X58 Xeon 5650

RAM is funny stuff it seems, you'd think I'd be able to run this Corsair stuff under 1.65v when running at less than half it's rated speed... but no!

I'd keep an eye out on that famous auction site for 2400mhz DDR3, as it's all rated at 1.65v from what I've seen and I can confirm that 8GB DIMMS (at least Corsair 2400) work perfectly fine. I did also run at 1800+ for a few bench tests before going for the higher speed and was surprised that I could get the timings from 11-13-13-30/31 to run at 9-10-10-26 fully stable.
 
I'm half tempted to send you a pair of my 8GB ones to play with! Only reason I ended up with 32GB was I got them cheap (job lot for £70... bargain I thought!) and Civ with some custom maps eats well over 16GB as does Skyrim lol.
 
I don't want to take this thread off it's current topic, but does anyone have advice for trying to run a 5650 with as low power as possible (no overclock, undervolting etc.).

I've got a plan in my head to build a server with the parts I have stashed in my garage (Asus Rampage III Extreme, Xeon 5650 and 32GB Ram). I've already checked they all play nicely together with their current overclock (it was my son's 4.3Ghz games machine), but its' future duties will be NAS, pfSense, VMware etc. and I'd like it to use less electricity than the tumble drier it'll be sharing a roof with.
 
The chipset uses a reasonable amount of power so I'm not sure how low you could really go with the power consumption. I know my overclocked system uses something like 140 W when idle, and that's with all power saving features enabled. At stock it might be like 100 W but that's still pretty high compared to current systems.

I calculated that buying new parts would pay for itself over using my X58 rig as a 24/7 server in something like 3-5 years due to power savings but I can't remember the specifics.

I'll go into the BIOS and turn off anything not needed, and drop all clocks back to stock (or lower... if that's possible).
This is to replace a HP Microserver (dual core, AMD thing). I figure a 6core 12thread even at stock will stomp all over it.

True. In 5 years, I'll probably have faster broadband and shoved all my needs into the cloud, or decommisioned some newer kit (maybe my sandybridge or my current 6700K) and moved that into the garage. This is more of a "I better do something with these parts, use them, sell them, or bin them" than anything else :)
 
I feel you, I really have no idea what to do with my current rig when I eventually retire it. I have a nice GPU, new SSD (2 TB MX500 for games :D), nice monitor, nice keyboard and mouse, it's just the base unit that is ancient (still going strong though). It's too power hungry for server usage IMO, although I hadn't considered undervolting like you suggested. The only thing I can think of is a workstation but there's no way I could bring it into work for that purpose.

I recently checked power consumption for a skt 1366 board that I was using for a mining rig - 113 Watts at idle for a P6T SE / Xeon E5620 (2.4Ghz quad -> overclocked to 3.8ghz) / 6GB RAM. That was as low as I could go disabling all unneeded onboard devices, and lowest cpu voltages that were reasonably stable.

So assume a modern system would be pulling 60 W when idle (probably less but let's be generous to X58), you'd be saving maybe 50 W. With 24/7 usage that's 440 kWh per year, which is £57 per year at a typical rate of 13p/kWh.

You can get a Ryzen 5 2400G, B350 board, and 8 GiB of DDR4 RAM for say £140 + £80 + £80 = £300. So buying an equivalent new system (albeit with better performance) would pay for itself in just over 5 years. If you wanted a hex core to replace an X56xx, you could add £20 and get an R5 2600...you'd need a spare GPU though. :p

I'm got 32GB of memory (for various VMs, NAS disk cache etc.), which at current DDR4 prices adds significantly to the replacement cost.
There's also other tricks that can be employed (shutdown during off hours - midnight til 7am for example) but this is more of a exercise in fun than real world economising.

What's your RAM config for 32GB? 8|4|8|4|8|empty?

You would be better off flogging the system parts on MM or eBay, them getting a 2nd hand gen8 microserver with Xeon and 16gb already upgraded. That's what I'm running for my home plex server and it did even serve as my gaming pc for a few years with a 750ti then 1050ti.

Where's the fun in that :) Besides Gen8 prices have gone up massively since people worked out the Gen10 was a dead end.

Plus I can't use my watercooling gear on a Microserver...
