70-80 tops, they can go up to 90 but then you are like at TJmax and so they throttle.

But the cooler you can keep = best.

I thought so. 4.6 I get in the mid 60s. 4.8 creeps into the mid 70s at 1.235v and then bluescreens on me. I daren't bump up the voltage any further at these temps and with this cooler.
 
4.7 on 1.300 nets me 81c max under realbench, 60-74c max when gaming. All dependent on ambient temps and wether i use an fps limit in games. My cards are non ref and add a lot of heat to the case.
 
What cooler are you using setter? I'm using a Phanteks and it did a great job with the 8320E I was clocking the other week. But I guess with Intel and fab size, heat generation is much more of a problem with voltage increases...
 
Got an Alpenfohn k2, similair in size/performance to a noctua D14. From what ive noticed with theese and ivybridge, a cheap air cooler will do pretty much the same as a high end custom water cooling loop. Its only when delidded that you see signifigant temp drops on any form of cooling.
 
[email protected] (ok its not stable as you say) is good, it will likely be the Vcore is not enough and thats causing the Bluescreens, if you can get that stable at anything under 1.3V then you have a good cpu.

I'm using one of these: http://www.phanteks.com/PH-TC12DX.html which isn't as huge as the K2 or D14. It just about fits in my case, so I'm really limited space wise.

Yeah, I was thinking it would be the vcore, but as I say, I don't think this cooler is up to the task. I think it could also be the board. I'm nearly certain when I was stressing the 8320E with IBT, that the Phanteks fans were a lot more aggressive on the Gigabyte board. The fans are reportedly spinning up to 1800+ rpm on this MSI board but I'm sure they were going harder on the Gigabyte board (though I didn't have a readout for them at the time).

Whats the error code for the bsod?
Click to expand...

Not sure. It was very quickly rebooting. Then I returned everything to default and installed Linux. Currently reinstalling a copy of Windows and going to have another play and attempt 4.7 and 4.8 @ 1.250 - 1.295 and see if it holds there and what temps I'm getting. I suspect it'll hit low 80s though. So might have to look at getting a bigger cooler.
 
IBT? you still using that?

Try ASUS realbench 2.0/2.2 (whatever the current version is), I find it a bit less at cooking CPUs.

Id download a copy of who crashed, (link below). Very useful for logging blue screen errors.

Also have a look in event viewer for WHEA event id 19 cpu parity errors, often a sign of lack of vcore.

Noted. Downloaded.

I was using IBT on the 8320E. I asked earlier in the thread about what to use on the 4790k and setter recommended Realbench, so I've been using that on the Intel chip. I did make one attempt with IBT on it just to see what would happen and temps shot straight up to 80c so I killed it and haven't used it since.

And thinking about it now, I might put the AMD rig back together and have another go at clocking the 8320E, but using Realbench. If I could get 4.4GHz out of it with IBT, I'm sure I could get 4.6GHz (which was throttling under IBT).
 
Avoid anything like IBT, p95 ver 28.5, the latter in particular will cause temps to skyrocket. In my case, 95c in 3 seconds at stock speed.
 
4.6GHz @ 1.230v and a max temp of 72c. Mostly it was hovering around the high 60s. Screenshot.

Going to stick with the same voltage and try 4.7GHz now.

Edit 1: 4.7GHz @ 1.230v and a max temp of 72c. Screenshot. Let's see if we can do 4.8GHz on the same voltage (BRING ON THE BLUESCREENS!).

Edit 2: Didn't even bluescreen on me. Just rebooted. Let's try 1.250v and if it's stable at that and a decent temperature, I'll work backwards.

Edit 3: Bluescreened out at 1.250v. Have kicked it up to 1.275v. Let's see what happens.

Edit 4: SUCCESS! 4.8GHz @ 1.275v and a max temp of 78c. Screenshot.

Not bad, Im just waiting on the final bits of my loop to arrive from OCUK so i can put it together and try my new 4790k, With custom loop im hoping for 4.8-4.9 (come on postie)

Nice chip there, can you run the benchmark in real bench, curious to see what your scores are like.:)
Click to expand...

Will give it a go now. Just went and set the settings in BIOS manually as I don't trust MSI command centre. So we'll see how it holds up now.

Edit: Any specific settings you want me to do? And how many runs?
 
Havent seen many of theese do 5ghz yet tbh guys. Mine in sig was got from another member on here, (traded for my first one). Ran at 5ghz for a super pi 32m run, but the volts needed for that were quite high. Both were much hotter than the older 4770k i had.
