That looks very good to me. Now keep going as that looks like a very good cpu.
Very good, 4.7ghz with only 1.26v. My old 4770K needed 1.35v for 4.7ghz
Is it stable at those settings?
Cheers guys just did 2 stress tests and 1 benchmark and didn't get any errors or BSOD looks good to me!
As above - on the face of it you may have a gem.
How long were your stress tests?
If they were of decent length i would use and abuse for a few days - as synthetic tests unfortunately don't guarantee stability in everyday use - and then shoot for 5GHz.
But that clock at 1.26v would be pleasing enough volt to clock ratio - but would be interesting to see if you get 5GHz stable.
Up to 2 hours
Yes, you got a bit more testing to do - that's your minimum really.
I used to run tests overnight - but i got fed up of running lengthy stress tests only for it to BSOD while browsing the net or using sketchup etc... Plus, modern CPUS and motherboards are far more accommodating/forgiving than they used to be.
Stress for considerably longer as that will at least identify quickly an obvious stability issue - but it won't identify cold boot problems, freezing, BSODs that you may experience in everyday use if there is an underlying stability problem. Only general everyday use will pick up these issues. All, takes time i'm afraid - things look hopeful - most would buckle after 5 minutes at those voltages...
With regards to most systems would buckle after 5 minutes at those voltages-can this be a bad thing in a way?
What's your to-go software for stress tests?
No, not really, it can fail for a lot of reasons - but thermal problems is not going to be one of them for you, even after 2 hrs, at 1.26v.
You could experience, freezes, reboots, BSOD, black screen, thermal throttling, warning "Error on core 4 expected 0.x..." (depending on software your using) etc...
Just reset - start the process again. Obviously, if this happens too many times you could experience Window problems due to frequent crashing - but they can be fixed with 'Last Known Good configuration' or system restore.
Adds to the excitement
I'm lazy now - i use prime95 (old school) and CineBench. With Prime i run small FFTs to torture the CPU and then a blend test as this pushes the memory and CPU combined - if i'm going to get errors i tend to get them during this test. But i go for modest clocks at the lowest possible voltage. That's why i like your 4.7 at 1.26v - it's a great clock to voltage ratio - but it's also fun to explore the limits for bragging rights.
Here's a link to stress testing software - clicky
Hello again pal, thanks for the links! I'm setting it going tonight at 8 and I shall leave it going for a good 4 hours. Appreciate your help and will post results
No problem - best of luck.
I've just realised you're the guy that bought it for a bargain too - this buy just keeps on giving...
What volts are you pushing to get 4.8?
Absolutely fine - great even.The same. Is this wise? Stress tests are ok.
