Intel 4690k overclocking

[Charmeleonnz]

Hi there,

I have a 4690k with a Deepcool Captain 240mm AIO

16GB DDR3

 

I am trying to overclock the CPU and at stock voltage I have it running at 4.1GHz, but when I push it to even 4.2Ghz it straight overheats to 100 degrees. At 4.1 it stays steady at around 80 or so. 

 

Why do 100Mhz make it overheat so much? I tried to go higher with more voltage which i can do at 4.5 but having to use 1.3v and well past 100 degrees which I am of course not happy to run at that temp.

 

Please let me know.

 

Thanks

Because even the slightest oc will have the mobo be more aggressive with power delivery and the cpu will have to do more work getting to that as well 

If you lost silicon lottery you won't be able to OC alot with out needing to up the voltage aggressively so I don't necessarily recommended going any further if your aio can't keep up

Are you using auto voltage on the mobo, if so that will tend towards setting a higher voltage with higher clocks, likely more than is required. A manually optimised voltage could help.

 

Otherwise, delid + liquid metal can help a lot.

I´m wondering why the AIO is performing so bad.

 

The 4690k I had some times ago would do 4,7ghz at 1.4vcore cooled with an older Noctua NH-9S, never to throttle.

for 24/7 use was running at 4,5ghz with 1.285vcore.

It depends on the silicon lottery and your cooling solution.

Ah that makes a of of sense, ill see if I can overclock and only put a little put voltage and see what happens otherwise ill stick to 4.1. Thanks heaps for the information

I was using Auto so that is probably the reason why it goes to 100 at 4.2 Ill see if I can play around with the voltage and see if I can reduce it while keeping the same clocks.

Same, It was second hand the pc so i replaced thermal compound and I have the rad on the top with two 120mm fans. Could be the AIO is just trash, otherwise Ill just stick to 4.1.

Thanks heaps
