Overclocking Xeon advice

[venny]

  I recently built a new computer which will be used primarily to create 3d animations and for rendering.  

  My PC consists of a:

xeon e5-2676 v3 (ES) according to CPUID

msi x99a xpower motherboard

32gb corsair vengeance lpx 2133

Cooler Master hyper 212 evo

nvidia GeForce 8600 GT ( will be upgrading this to a quadro m6000).

samsung 850 evo 256gb ssd

segate  3tb hdd

 

My question is this. Linus has a video where he gives a Xeon a slight overclock by increasing the BCLK. He also demonstrates that the multiplier can't be changed. However I was able to change the multiplier to my CPU from auto to x27 and CPUID recognizes that my CPU went from a 2.4 MHz to 2.7 MHz. Does that mean my multiplier is unlocked? Should I try changing other settings to get more performance? Temps are sitting around 70c at 2.7 MHz on aida64 stability test.

Does the multiplier go any higher than 27 ? Officially , the 2676v3 isn't in intel's database and was never released, so i can't tell you how far it boosts . It may be that you are forcing it to boost on all cores .

Thanks for the reply back Coaxialgamer. I tried changing the multiplier to x29 and it saved it in the bios but cpuid says that it's on a multiplier of 27 even though the bios says differently. The cpu specifications in bios tells me that the cpu ratio is unlocked but x27 is the most all 12 cores will get. Aida64 report confirms this.

Max Turbo Boost Multipliers   1C: 30x, 2C: 29x, 3C: 28x, 4C: 27x, 5C: 27x, 6C: 27x, 7C: 27x, 8C: 27x, 9C: 27x, 10C: 27x, 11C: 27x, 12C: 27x

 I ended up setting the CPU ratio to auto and increasing my BCLK to 105.4 which gave me 2.8MHz. I stressed tested it for about 12 min and CPU temp was steady at 80c and
 my memory went from 2133 to 2400. I don't know if I should increase the BCLK more, the TjMax Temp on the CPU cores is 103c. Also, I'm wondering if the temps I'm getting 
are normal  for the type of air cooler I have. I didn't have that much thermal grease to begin with, but I dont know if adding more would help get better temps. I guess I would 
just have to test it out to see if it improves.
