Looks like I got a good 'un (5960X )

I was holding off upgrading my rig to an x99 platform until the Broadwell-E chips came out, but I got the chance of a 5960X at a really good price.

I've been playing about with finding out the best O/C I can get with the chip and I've got to 4.5Ghz at 1.23V :). The temps are very good also.

Running a custom loop with 1 X 360 and 1 X 240 Rads. Also have a GTX980 in the loop.

I can get it running at 4.6Ghz with about 1.29V with the temps running to the mid to high 60's.

I'm happy with 4.5 for 24/7

Overall a happy camper.

4.5 across all 8 cores at 1.2V for a 5960X is pretty good going.

It's not all about the max clock speed. For me it's about the combo of voltage, speed and heat management.
 
Ahh yes I suppose so, if it is sitting at 4.5 on all cores at once at 1.2V! :D

I just saw the clock speed at first. Nice one! :)

Are you running 24/7 @4.6

Also interested to see what temps you're getting

I was getting around 65-69 degree when rendering with 3dsmax sometimes 2-3 cores bumped to 75 degree. It was under watercooling.
I sold that one and bought a 5820K instead. :D
 
Tested? I can run 4.6Ghz at 1.25v on mine (well i'm building it for my dad), can run cinebench all day long but it crashes out on prime 95 within 2 minutes and bsods and reboots on games etc.. needs about 1.3v for stability but the cooler will never suffice once its in a case. 4.5 needs 1.265v for stability but going to settle at 4.4 1.24v, can do 4.4@ 1.235v but giving it a slight bump never exceeds 80C in small fft in 30c ambient, prime95 blend 24hr stable and rock solid in gaming.
 
I haven't done extensive stress testing. I'm a bit nervous about frying chips, and I don't have any fish to hand. ;)

It's happy doing media transcoding through Handbrake and encoding through Premier for over an hour.

I did a 1 hour run on prime95 v26.6 with no issues so am pretty happy with it at these voltages.

Interesting article on stress testing 5906X here

http://www.tomshardware.co.uk/answers/id-2557021/prime95-test-question.html

Do NOT run any versions of Prime95 later than 26.6. Here's why:

Core i 2nd, 3rd and 4th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95, such as 28.5, run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces extremely high temperatures. The FPU test in the stability testing utility AIDA64 shows the same results.

Prime95 v26.6 produces temperatures on 3rd and 4th Generation processors more consistent with 2nd Generation, which also have AVX instructions, but do not suffer from thermal extremes due to having a soldered Integrated Heat Spreader and a 35% larger Die.

Please download Prime95 version 26.6 - http://windows-downloads-center.blogspot.com/2011/04/pr...

Run only Small FFT’s for 10 minutes.

Use only Real Temp to measure your Core temperatures, as it was designed specifically for Intel processors: Real Temp - http://www.techpowerup.com/downloads/2089/real-temp-3-7...

Your Core temperatures will test 10 to 20C lower with v26.6 than with v28.5.

Please read this Tom’s Sticky: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temp...

Of course, if I do find it needs a little tweak on the voltage front I'll increase a step at a time.

26.6 is not really stressing the cpu. I've done quite a few Haswell based oc's and have run all with the latest versions of prime with proper AVX2 extensions, it does lower your overclock as you'll find non AVX2 things stable whereas AVX2 needing more vcore and producing more heat, but at least you know your cpu is stable as a rock. Not seen any real evidence of p95 killing chips.
 
I'm extremely torn between 5960X or just waiting until Broadwell-E

I want some of that Samsung 950 Action and my motherboard is rubbish! Well not really, it just doesn't have that M.2 slot

Not sure id risk a £600 CPU running a version of Prime known to cause issues though.

Exactly where I was.

Having said that when I started to buy the bits for the new build the new X99 motherboard from ASUS came with a M2 PCI riser card. Just for fun I plugged it into my x79 Pro, slot 4, connected the 950 pro and it worked like a charm.

Nice, for me though, If I'm going to do it I would rather do it properly.

Curiously though how much did you get your Chip for? I can then price it all up.
