my 7600k

[eddycuss]

i am upgrading from my ADM A10-9700 APU to a 7600k. i have looked into potential overclocks for this cpu and i have seen that people are getting upto 5.0ghz from the 7600k. what would be the best air cooler that would hep me achieve a stable overclock cllose to the 5.0ghz that i have read about. 

 

has anyone managed to overclock a 7600k to this extent using an air cooler? If so what cooler did you use?

Consider the i3-8350k also. Like the 7600k it is quad core, but has slightly more cache at 8MB compared to 6MB. My 8350k seems stable at 5.0 GHz 1.4v-ish for things except Prime95, which I haven't separately tested yet. I'm using the Noctua D15 cooler on it, and it seems fine even without delid. I didn't get any further in OC after delid.

this is my first intel based build, whats the best GPU to pair with the 7600k

prime95 not stable = chip not stable all it does is calculations and trust me, it is stable on any stable chip

please dont waste your money on a 7600k when you can something better for the same price like ryzen on cofeee lake

Hi, what will you be using it for? just gaming? mix of gaming and compute tasks? and what is your budget for cpu/mobo?

I've had computers that p95 would crash but no other task that I did caused it any issues, so meh, if your cpu is stable enough to do everything you want why give a crap about a synthetic test not being stable

yeah because not stable

 

i once ignored a p95 crash while every other test and benchmark was stable, 2days later bsod 2months later file corruption in windows

If you're ONLY gaming, I'd stick with intel, if you're into heavy multithreaded tasks such as encoding/rendering (assuming they are CPU dependent) etc, OR you want a board that you'll be able to use with a refreshed CPU SKU in the next 4 years, then I'd go with a ryzen build.

This one below is ONLY the CPU/mobo so far... and you WILL need decent RAM of approx £130-180 approx for 16GB currently.. theres' nothing to be done about that RAM prices are insane right now and getting worse. You however may not need a separate cooler, the 1600 comes with one that is good enough upto around 3.7/3.8Ghz OC... but you WILL also need a GPU, the ryzen CPUs do not have iGPU.

thanks but i really dont want to go with AMD on this build

It is common for Prime95 to require lower clocks than other tasks (at a given voltage) to be stable. That's why Intel recently added AVX offset ratio so you can set them separately. The feature isn't present in Skylake, but is present in Skylake-X and Coffee Lake. I don't have Kaby Lake myself so not sure on that.

 

On my sample, I simply haven't got around to doing in depth testing of Prime95 stability yet. I should add, I use recent Prime95 using FMA3 instructions. I do not use old versions using lesser instruction sets. The typical workload of my systems is equivalent to running Prime95 24/7 (software uses same math library as Prime95).

The i5 7600k is a terrible choice

just get a much cheaper b250 motherboard and a locked i7 7700 it will perform with superiority at every thing while being cheaper since you can use a stock cooler and all...

 

If you totally want to overclock get the i5 8600k instead as it somewhat makes sense OC'ing i5's on z370 again.

if any instructionset isnt stable it means the chip just isnt stable, theres no excuse to it, unless u wanna deal with a not 100% stable chip

There is no such thing as 100% stable. And again, Intel specifically gives you the ability to clock different parts so they can be separately optimised. Look at this Xeon for example: https://www.anandtech.com/show/11544/intel-skylake-ep-vs-amd-epyc-7000-cpu-battle-of-the-decade/8

 

We have the same ability in recent Intel CPUs to set different clocks for different loads in a similar way.
