Overclocking my new 6950x! 4.3Ghz GHz 1.277v Temperature Question? - Page 2

Yeah after some more research, you're right. It's a pretty big air cooler I have and I tried putting some beast fans on there, very similar temps. I'm not terribly fussed though because it does have 10 cores after all so I dropped the OC down to 3.6ghz at 1.24v and have much more manageable temps now and CPU still only around 35% usage when I'm performing all the tasks I need to and running a game while waiting. So plenty of headroom smile.gif
No I didn't. I'll definitely look into that...especially with the price of this chip. Do you have any experience with their protection? I've backed off to 36 x 101 with vcore of 1.24 and it's stable 3hrs so far with temps more manageable, around 80C average with those spikes I mentioned above only going to around 90C, sometimes 91C...

At the end of the day I don't need to OC it that much, as I mentioned above, currently at 3.6ghz Im only at around 35% load with ALL my tasks running and playing a game while waiting.

No I haven't run their overclocking software, should I? Whats the benefit? I've done it all from BIOS (I'm an old school LGA775 overclocking kinda guy lol)

Thanks for all the replies =)

Well what case and ambient temps do you have. 30-40°C on idle is quite high unless your voltage is set to override and not adaptive. Although we have vastly different cpus i didnt gain too much (at first) from my nh-u14s to custom watercooling went from 54C to about 49C at 1.088v now at 1.2v running bare die its at about 49°C so i gained 300mhz and the temps stayed identical.

I would try lapping it though youd be shocked at how much better the temps will get. This is where pressure paper really comes in handy.

If you want you can remove the cpu and check the ihs and heatsink with a straight edge youll know how flat it is. The better both surfaces match each other the less tim youll need and the better the temps will be.

You can still get lower temps with this option if you want.

Eh that tool is ludicrously expensive for what it is 70€ for two pieces of plastic no thanks. Also its such a minute difference in temperatures on a soldered cpu its not worth it. Again youll see way WAY lower temps by just lapping both to get even and increased mounting pressure.

I think thats the issue here.

I think you're right.

I'm gonna give that a go during the week and see what happens. I did actually notice when I pulled off the heatsink during my remounts, the middle of it had noticeable less paste on it than anywhere else which leads me to believe that its perhaps curved a little bit. I noticed this everytime I remounted so I know it's unlikely it's something I did.

Well less paste is exactly what you want. if its in the middle it means its convex so it might not be putting enough pressure on the rest of the IHS.

Thanks for the advice mate, appreciate it. Didn't even know that existed.

My 4790k was @$30 and my 5960k was @$35. I think you get a 1 time replacement no questions asked from Intel if you OC and kill it. Thank goodness I have never had to use the plan BUT good protection. I'd pay $50 if I was buying a $1730 chip!

70 Euro does not seem that much after you bought a $1700+ CPU. I think the bigger concern is that the risk of killing your chip is huge if you don't do it right.

True but totally overpriced for what it is. Honestly anything soldered id leave it alone and do a custom watercooling setup. Those cpus put out quite a lot of heat. And now with more efficient gpus you really only need 2 rads.

Remember with these things you aren't paying for the pieces of plastic/metal, you're paying for his time inventing it. He's not going to sell a lot of these and has to price it accordingly to make it worth his time. We are paying $1700 for a piece of silicon that can't have cost more than a few hundred dollars to produce tongue.gif

Hi,

This may seem like an obvious question but, how long were the cores running at 100% when you took this screenshot of the temps. Was it seconds or did you give it time for the temps to stabilize? Also you should consider at least an AIO water cooling solution.

While this CPU does well overclocked, looking at your voltage and clock rate, stability may become an issue and temp issues and variations occur on the 6950x, especially at higher temps with marginal cooling. Most of the CPU's of this type I have tested and seen run better at around 4GHz (even though they can clock higher).
