4790k 5.1GHz stable @ 1.42v. How to get more?

post #1 of 5
Thread Starter 
This isn't for 24/7 I just want to see what my chip is capable of. 24/7 is 4.8 at 1.275v. I can get 5.0 stable at 1.365 and 5.1 at 1.42. I can get into windows with 5.2 @ 1.48 but it crashes shortly after and it seems that any higher voltage is even less stable. I have only touched the multiplier and vcore voltage. What more can I do to try to get 5.2 or have I hit my limit?

What are you considering 5.1 stable with? screenshots with some prime95 running?

If your chip is as good as you say it is, keep it at 5 GHz and 1.36V. That will be safe for quite a long time from now. I've worked with a dozen or so Haswell/DC chips and you don't want to run those puppies higher than 1.4V for a prolonged period. I had a 4770K degrade at 1.42V within months, your mileage may vary.

PS: Don't ever use Prime95 on Haswell/DC or Skylake chips. it draws way too much power and is completely unnecessary.

"stable" is more than a little generous. I just booted up, ran super pi 32m and called it a day. I didn't even try to run prime95. I just left for work, but I'll give it a try tomorrow morning.

I did run prime95 and Firestrike at 5.0 with no problems.

It's just for a screenshot. My 24/7 is 4.8 @ 1.275. I didn't do excessive stability tests at 5.0 but all seemed well for what I did. I'll do some more tests tomorrow.

I'm not a huge fan of prime95 either. What would you suggest? I've used aida64 with success.
