If there is any, it's negligible.So, still wondering, is the performance of these chips mangled at all by the presence of the DDR3 IMC when using it in a conventional DDR4 system like a Dell M630?

Its a synthetic benchmark but Geekbench v4 shows E5-2678v3 All core turbo about doubles multi-threaded performance vs stockHas anyone tried the all core turbo mod on the 2678v3 on Linux? I'm going to go for it tomorrow, ~10% more speed with no additional heat or power consumption looks like a no brainer.
As in you have a liquid cooled 2u computer..? They look rare -- though I'd think it'd be cheaper for big server farms to run water pumps than ACs... you know, have radiators outside and a water-circuit. But then again, the resistance to push the water might approach the energy required to run a compressor ...IIRC, it should reduce the idle consumption. I was looking try this last year when I saw the thread on AnandTech. I wasn’t sure if the 2u cooling is enough for the full turbo for dual procs and did not venture any further. @Marsh has been using the all-core turbo unlock.
How do you edit the microcode in the CPU..? Is this something in some manufactures bios..?Hi, I am the author of v3x4 and perhaps can answer any questions anyone may have regarding the Xeon v3 All-Core Turbo workaround.
For dual CPU configs, I would recommend C3 Enabled and C6 Disabled for maximum performance.
Microcode of choice (for me) is 0x27.
Not edit, remove. And even that is not a proper description. Every (Intel) processor comes with a base microcode instantiated in hardware. As the processor matures in design (and even beyond) there may be discovered necessity to make changes. These changes are incorporated by Microcode Patch Revision level release for hot-patching at boot (by BIOS/UEFI) or at OS load (Windows, for example, does this).How do you edit the microcode in the CPU..? Is this something in some manufactures bios..?
I've never even heard of this. Also -- how much of a difference do you notice...?
Do you liquid cool your servers..? If so, pictures? :-D
Welcome to the STH community and thank you for the offer to help. I believe you have the files on github repo.Hi, I am the author of v3x4 and perhaps can answer any questions anyone may have regarding the Xeon v3 All-Core Turbo workaround.

I have couple of variants of Supermicro single socket boards. X10SRA & X10SRH with V3 CPUs.
I recall vaguely reading that lack of heatsink on the VRM, SM boards are not preferred. Also, by the time I saw the thread, some of the links to to download the required tools did not work and I did not pursue any further.
I’ll restart the project in the next few days and seek your help.
There is also more professional solution from Alphacool:Do you liquid cool your servers..? If so, pictures? :-D
I have a few of these combo's extra with up to 128GB DDR3. If anyone needs for a good price send me a PM.Currently running E5-2678V3 on HuananZhi X99-TF with 32GB desktop DDR3 RAM (Mushkin Redline 4x8GB 1866Mhz, Quad channel). I performed turbounlock by removing microcode in BIOS using Miyconst tutorial (see his Youtube channel for an excellent and detailed tutorial/guide and link to all tools). CPU cost $85 on eBay, X99TF cost $100 on AliExpress. All core turbo unlock resulted in 3.3Ghz all 12C/24t. Temps remain below 60C on SNOWMAN 120mm dual fan 6 pipe air cooler in Prime95 (v.26.6). Cinebench R15=1825; R20=3912.
Currently, AliEx offers package deals: E5-2678v3 +X99TF + 32GB REEC 1600 DDR3 for $250.
Tight timings preferred over highest frequency.
There are a handful of X99 motherboards that support DDR3: HuananZhi X99TF (4 dedicated slots DDR3 OR 4 dedicated slots DDR4) or HuananZhi X99T8 (8slots DDR3). Both are quad channel up to 1866Mhz on DDR3. For DDR4 it is max 2400Mhz. The other variants like the HuanaZhi X99F8 and JingSha X99D8 are DDR4 only, to my recollection.
IMO, very good quality; tops for a chinese motherboard and you would be hard pressed to see difference with name brand mid-level board.
2 x NVME m.2 + one m.2 for wifi/bt card. NVME bootable OS.
Depending on where in the world, the landed costs for this setup are very compelling. For places like USA, probably better to stay with Ryzen, given its compelling landed costs and price/performance.
