Intel Xeon E5-2670 Boost clock

I am just wondering if there is a way to keep the boost clock for the Xeon E5-2670 at a constant 3.1 to 3.3 Ghz or even just 3.0Ghz? I am planning on building a dual cpu build and just want to know how much performance I can get out of it.

just wanting to know. What do you intend on doing with the build?

I intend to run some game servers,(minecraft,TF2,Nether,lfd2, stuff like that) and I also am going to use it to just experiment on and try to learn some new things here and there. I am going to be in college soon for computer sciences and programming, and I am also getting certifications in security,networking, and A+(compTIA certifications) . I might use it to test to see how well it would be at rendering videos and other files as well. That is just the little that comes to mind. :)

I have two of those machines and when needed they will boost 3GHz all day on all cores. But as far as I know that is mainly board dependent. You have a parts list yet? If you don't, take a look at this one: CLICK

It is a heavy hitter when it comes to video encoding using handbrake. I am currently converting my blurays into x.265 .mkv files with vorbis stereo audio. A 90 minute movie ends up being around 2.5GB and looks stunning.

OP - What version of CPU are you referring to? 2670, "V1", V2, V3, V4? Did you already buy these CPU's? If you haven't, consider skipping "V1" and V2 all together.

You can get something like this - http://www.ebay.com/itm/272254848452 E5 2683 V3 (OEM NOT ES) for $350 Add a $250 SM motherboard, and some ECC DDR4 (which is very cheap right now) and you have a really nice system that is significantly more future proof than a V1/V2 system. Even in a single CPU system you will be down cores vs dual 2670's but you will have better overall performance and a significantly less power bill. You could also go dual CPU with these, good boards start at around $350ish, so you have looking at roughly $1000 for 28 cores, 56 threads.

In regards to your original question. On most boards (maybe not OEM's like Dell) but SM, etc, you can basically force turbo at all times. However this is also OS dependent. Not sure if you plan on running ESXi or install OS directly to the hardware?

Are you using makemkv? [sorry for HiJack OP]
knowledge of any free bluray playback software?
I've got a stack of blurays I can't watch

disable boost and "overclock it" to 3.3. my xeon 1231 is at a constant 3.8. also i suggest using a cheap cooler like the 212 or something instead of stock so you can keep the temps down and improve the life of the cpu, prevent thermal throttling, and keep down the noise.

and guys it doesnt matter what he wants to do with it. the solution is the same regardless. also my asus board auto oc did this in seconds btw so if you want to go the easy route you can just get a asus board.

And I am still looking into a server chassis because I plan on having a server rack in the near future, but I am not sure which case to go with and what size yet, I am thinking 3U at the moment but not sure yet. And also, the rest of the parts (power supply,etc.) I will look into later, but those are the main parts right now. And also I am going to be using a bunch of adata or mushkin ssd's for the build as well, just depends on prices when the time comes.

Please listen to me! Trust me when I tell you this, skip the old hardware! I know the prices are "too good to be true" but investing $300-400 on a motherboard just to run some old ass $150 processors makes no sense, it locks you into old gen hardware and your upgrade path is zilch. It is silly to spend $400 on a 5 year old motherboard. Not to mention the power usage.

Grab a C612 (X99) SM motherboard. You can get a dual-socket board for the same amount of money, grab one of those E5-2683 V3's, and upgrade to a second CPU in the future. Or if budget permits get two now.

Yes you will spend more but you will have a server that is this gen, not three gens ago. This is a non production home environment, you don't need to have two CPU's or even 128GB of ram right now. Build what you can afford now with upgrading in the future a option and use newer hardware.

This is what I would recommend....

1) disable C states under bios, and set it to high performance.
2) set high-performance profile under power settings under os.

Yes, makeMKV for ripping and handbrake for the conversion. I am not watching the discs on the computer so I can't help you there. Sorry.

I think it's important that you figure out first where your bottlenecks are.

I assume you'll be running linux and if that's the case, you can enable cpu scaling via kernel. Some other things to note: hyperthreading doesn't necessarily equate to better performance - in fact I've found that it can decrease performance. You may want to play with cpu affinity, scheduler type, and priority. If you're network heavy then moving all your interrupts to a specific core is usually helpful and if zero copy is available that would be worth looking into as well.
