Well thats a good news and that temps are OK for the prime 95,some ppl. leave the prime 95 to work for many h I do not prefer that but I instead like to do multitasking while prime 95 is working prime&cinebench or some video editing and then I could be sure that CPU is stable but even then sometimes if PC froze or some other instability happens you should tweak core V or go a bit higher or a bit lower on your frequency sometimes cpu-memory simply do not like to work on certain speeds ....so you can go a bit higher on CPU speed but also you must tweak your mem speed /timings and the NB freq. and then do more testing.......GL

well as we speak.

booted into bios to change the NB frq. no matter which one i chose it kept saying 'overclocked failed'

so just changed it back to default bios settings to actually boot up.

really strange that this hasnt happend before when booting my pc.

Well....you probably doing something wrong there.....
Here are my Clocks Cpu/Nb/Mem/QPI and the Cinebench result

Ahh yeah also I updated Bios with that latest Spectre-Meltdown protection which lower a bit my overall score(it was around 940 on this speed)

 

[lexluthermiester]

Do you reckon this just a blip or do i need to change something else.

Given the symptoms, my guess is that your ram does not like the overclock. Whatever settings you choose, make sure the ram is running within 2% of stock. The CPU can handle 4ghz. Also you have your RAM command rate set at 2T, try 1T and see if that helps stabilize things.

I agree....I also do not think that CPU speed is the issue here it´s probably something in correlations of the MEM-NB-QPI

 

[Caring1]

Increase the Bus speed and lower the multiplier.

That's odd - never heard of motherboard bootup issues like that. I'm glad I went with gigabyte now.

 

[phill]

One thing I always learnt when overclocking/benching for teams, do one thing at once and leave things like memory at stock until you have found what you wanted from the CPU. Never try and overclock the CPU and the ram or anything together as it will only add complications..

Overclock the CPU and then tweak the RAM and settings then.. Makes life so much easier for yourself and that way you can find the limits a lot easier Simple tests like Cinebench 15 will be fine for stability or even wPrime (1024m test) just to make sure it's got enough voltage etc.. Then you can step up the stress testing if you'd like and go from there

 

[stuartb04]

seems i have a stable oc for now.

cinebench score has gone down though.

20 mins of prime95 ran fine passed.

i basically followed this video.

should i change anything else or leave it for now.

Well now seems like you finally did a good job when it comes to the QPI&NB&Ram,However your cinebench score is low but that is because your HT(Hyper-threading )is OFF you gonna need to go to the bios and turned ON your HT otherwise if you don´t you will basically work now ONLY on 6Cores/6 threads instead of 6c/12Threads....GL

yep.thats better.

That's it my friend.....you did it.....now just make sure that everything working stable......

 

[Regeneration]

HT on increases temperature by 5-10c and requires more voltage.

 

[Zyll Goliat]

HT on increases temperature by 5-10c and requires more voltage.

Well that is true but also giving you 2x more threads and overall much better multi-core performance.......

 

[lexluthermiester]

and requires more voltage.

Not much more. Not enough to make a difference to the OC being applied.

 

[Regeneration]

HT delivers better performance, but it does make a difference to OC stability: more vcore or lower clock by 200-300 MHz.

 

[FireFox]

HT on increases temperature by 5-10c and requires more voltage.

Agree on that.

I can't live without HT i am one of those who prefer slightly less OC with HT on and a stable system rather than a higher OC with less voltages and HT off.

 

[lexluthermiester]

The point I was trying to make was that for the OC in this discussion, not being an extreme OC, is going to be unaffected by HT being on. At most he might need to bump the CPU voltage up by .125v, which is not going to increase temps much.

And it drops half the threads - just not worth it.

Sorry but you got that wrong
Enabling HT doubles the Threads
" and its disabling HT that Reduces the Available Threads.

 

[phill]

If you have HT, you may as well use it Nice work on the overclock I must stop looking at this Xeon thread, keeps making me want to find older Xeon's for my 759 and 762 boards to replace the 920's!!

Reread? I said it drops half the threads.

 

[dorsetknob]

6 Core CPU 6 Threads (with HT enabled =12 Threads)
6 Core CPU (with HT disabled = 6 Threads)
On that i hope we can agree .

Work on your interpretation and maths skills
6c12t with ht
Without ht on it halves the amount of threads.
Tired?

Which is what i replied with
I'm Sorry if you fail to understand what i wrote and it shows that i do not need to work on my skills
