At that point you would be playing with either hardware or firmware. Modifiying OS behaivior alone won't do it.

Depending on the model there might be some room for boosting TDP or frequency response curve, but the maximum multipler is definitely locked.


There was a microcode bug that allowed 4**0MQ/HQ laptop CPUs to be multiplier unlocked. We can dream about the same thing happening on Xeon E5's. Really high clocks on all cores still won't happen though. We'll run into power/thermal limitations. (Imagine trying to handle two 6950X in one socket.)

Yeah.... Please... We /I am ready for that... Dream......
Oh.. And that means a simple(well not simple to be honest) microcode changes can allow us to change max multiplier?? Sorry for being noob and asking too many questions....

All this talk really makes me want to hold onto my Rampage V Extreme instead of selling it now that i have the Rampage V Edition 10; and using it as a backup rig for video editing. I've been debating what to do about my CPU situation for some time. I like my i7 5960X because it bridges the gap for both rendering/editing and gaming, with 8 cores being great for the rendering and editing aspect and the 4.5ghz @ 1.3v + 4.3ghz cache overclock giving it good gaming performance.

I have a binned i7 6800K coming thats tested at 4.4ghz @ 1.344v or less (on an H100i AIO cooler, so my 480mm + 420mm + 360mm radiator setup should be able to hack it at 4.5ghz at under 1.4v stable especially since i'm looking into the LGA 2011 delidding tool that gets 6-10C temp drops which should curb the excess heat)

My thoughts about the 6800K was that

A) It would save me money as i can sell my 5960X for more than i paid for the 6800K

B) The ~8% average single threaded IPC increase over 5960X will give me better gaming performance as a 4.5ghz 6800K would be equivalent to a 5960X at a whopping 4.86Ghz!! (minus the extra cores of course) So i'd basically be giving up two cores/four threads in exchange for a couple hundred dollars in savings and an extra 2-3 fps in games, which isn't a terrible deal really; ESPECIALLY since i can make a (relatively) cheap Xeon rig do handle my Video Editing work and run pure gaming on the 6800K + GTX 1080 setup on my main rig.


Question is, which Xeon would be the best choice....i don't REALLY need a Rampage V Extreme for a Xeon editing rig though lol so i could sell that, and perhaps just get one of the 2670 V1's and a cheap X79 (although X79 boards are insanely expensive nowadays due to being out of production for a few years) The irony is that it would probably STILL be cheaper for me to get an E5 2670 V1 8 core SB-E chip and a WHOLE backup PC with budget parts than it would be to simply get an i7 6900K lol. With the money i'd have left after selling my old parts and covering cost of the 6800K i could easily get the 2670 V1 and an X79 board + ~32gb of ECC RAM, a cheap mid-tower case, like a 212 Evo (since i won't be able to OC it being a Xeon), and a ~1tb HDD etc.. for maybe $500ish.

If it's an editing setup you want, this paired with 2x E5-2670's and 64-128gb is by far the best value right now, just need a case that supports EEB.

2x E5-2695 v2's would be pretty nice as well with 48 threads. smile.gif
Too bad the less expensive ones are Engineering Samples.

Yeah but i really wouldn't need that many cores/threads and that much RAM. The editing and rendering i do is just for youtube videos and such. I just do H.264 encoding and stuff of streams mostly; and i do general creation of video intro's and stuff in Blender and After Effects CC on occasion. Not a heavy user at all, certainly nothing "professional" anyway.

I was actually quite happy with my editing/rendering etc.. speed on my 5960X with 16GB DDR4 2666mhz RAM. And if i would have an entirely separate PC doing all my gaming and web browsing etc.. i would have even LESS need for massive resources since this Xeon Editing PC would be ONLY for editing and nothing more.

Although i suppose one thing that might be a good investment is a 10gb card and another SSD for the backup rig since i would end up having to transfer all of my video files from my main pc to the Xeon rig.

In that case you might be fine with the 6800k, but encoding times would be about cut in half with 2x 2670's.

I'd still get 64gb on a dual socket board so you can run quad channel. 64gb/1600mhz of registered ddr3 runs around $100 or so.

I see there are two stepping in e5 2670 v1. C1 and C2. What's the difference? I guess C2 is better? Newer?

Newer, yes, better...?

Both C1 and C2 are retail steppings. Either will be good.

If I remember right, C1 does not support VT-d. It was fixed in C2.
