Need Overclocking Advice

[SuperShermanTanker]

So I recently overclocked my i5 to 4.2ghz at 1.18 volts and it looks like the temps are under control on my i5 4690k that has a hot core in which IHS is messed up on the first core on my CPU and I'm not ready to try and delid the CPU yet so I'm trying to get what overclock I can with that bad core. Here are my temps in Open Hardware Monitor while hammering the CPU with Folding@Home using both the downloaded client and the Google Chrome client at the same time. I did test it for a few hours with Folding@Home running and I was playing Overwatch at the same time basicly hammering the rest of the system along with hammering the cooling in the machine. For the 2 hours I was playing Overwatch it was stable and didn't bluescreen.

 

Here are the temps I got after those 2 hours:

 

Anyone have any advice or comments? I wonder if I should try to turn down the voltage a bit and see if it's stable because I know the voltage is the biggy when it comes to the heat from overclocking or is what I have dialed in right now fine?

you should stress it with aida64 and see the results instead of overwatch.

I had folding@home pegging the CPU the whole time

1.18 is super low in terms of OCing 1.4v is the ceiling for what's safe over the past few years for intel. Try a stress test like ROG realbench and see if it does the same thing. Games tend to be single core intensive so it could be stressing that one core in more ways by playing overwatch and f@h at the same time

When I have a few hours that I'm not going to use the machine I'll let prime 95 or aida64 peg the cpu to make sure it's 100% stable

even in aida64 and prime95 at stock speed my CPU has that problem where the first core is way hotter then the rest

He's got a 212 Evo I would go anywhere past 1.35v and even then it gets pretty toasty with that

well, could be the tim that intel used, could just be a lame core with a little more slop

that wouldn't account for a single core being considerably hotter

I know but just watch that core. Around 80-85C you should stop pushing the voltage. Also I've got the same issue on my 6700k, one of them is always 7-10C hotter then the other.

yah I used my Z97 Asrock Extreme 4 motherboard's auto overclocking feature and it set the clock to 4.5 ghz at 1.35 volts and here are the temps I got and as soon as I ran prime 95 it throttled to oblivian and you can clearly see my problem with my IHS on my first core here and it's not my thermal paste application under the CPU cooler I reapplied it over 10 times with the same results before

Nice to hear I'm not the only one with that issue

Will be sure to keep the bad core temps in check

you could do separate core OCing so the first core isn't trying to go as hard as the other 3

At what temp does that CPU throttle as 90c or so seems a tad low for throttling to kick in?

How exactly do you propose that he accomplishes this?  You can't set custom multipliers for each core.

[Cyracus]

I can on mine, and the last system I had... didn't realize it was anything special

forgot to quote you so you'd see my response and can't seem to find a delete post button so....

You're mistaking what you are seeing.  You can do a "per core" overclock, but that is not setting different ratios specific to each core.  All it does is adjust core multiplier based on the amount of cores being used.

I can find basically nothing on the subject so I'm gonna just accept that I was mistaken

Just did a almost 5 hour stress test with aida64 and it still hasn't crashed

Wow.  20c between the lowest and highest core.

I said my IHS was screwed up and good proof right there

[RxL]

To the OP all processors have a single core is always hotter than the others my 5930k is a 6 core 12 thread and  core 3 is always higher than the rest same with my 4790k that I used to have
