I do 20 runs on maximum memory. Then to fine tune it use Prime 95 blend for 5+ hours or OCCT test (not Linpack test, that is for heat generation) for 5+ hours. If you don't get any crashes you are pretty stable, if you do however you may have to either raise the voltage or lower the multiplier. I don't use Aida64 anymore because it doesn't detect instability as well as other stress tests. Besides my trial ran out a few weeks ago and I am certainly not paying for that program.

Okey. I will try. I let it over night and after 7 hours in AIDA it still running. But I had to increase Vcore to 1.260V for 4.7 GHz. I'll let it until I will get back from the work.

I have temperatures on the final line with my cooler. So I will not test more than 4.7 GHz. I'm thinking about delliding.. .smile.gif

BTW: I don't wanna test it in last Prime95 because it has AVX and it increase heat and also Voltage. Last version without it is 25.11. Is it okey to test it with this Prime?

IBT I will try soon as I can... Thank you... smile.gif

according to this thread on first page:

it say that ring voltage max is only 1.35 on air

Don't go crazy stress testing, but don't settle with a half assed OC either. I don't like telling others what to do with their stuff, I just like to let them know what I do and offer an opinion. So I am not saying that there is one way to stress test, I am just saying that it is good to mix them up a little because some focus on specific parts of your system (CPU, RAM and cache, heat output, etc). Also there is no specific time threshold (or number of runs) for any of these tests, just don't rush them either. You will eventually figure out what tests are right for your specific usage and get your own routine with programs you like through trial and error. It all depends on what you do daily with your CPU. I occasionally do some MPEG 4 video compression so I need a stable OC or I risk wasting time compressing large videos.

Almost all stress tests will incorporate AVX instruction sets, just make sure you have your Core Voltage set to manual and not adaptive when you are stressing. You can find your settings on manual and then switch to Adaptive later if you like. Like I said before it seems like you have a very good chip, so don't be afraid to up the voltage if you get a BSOD instead of dropping the multiplier. You should be able to stabilize that OC with minimal adjustment. Let us know how you make out...

I was running 4.5Ghz @ 1.2 v with Vcore set to manual. Turned on adaptive and it lowered my vcore to 1.12 to 1.124 and its still stable as it was.....Adaptive works for me !

I think every CPU is different, mine is x38 and 1.050v.

Or board for that matter if Gigabyte decided a high auto voltage for them

1.26 vcore is high for 40 multiplier. did you try the 3 step overclock to test your cpu ?

First time poster here. Noob overclocker

Got a 4670k that has had a delid. (service provided by an extreme overclocker near me)

On air cooler (Cooler Master Hyper 612) I get 4.9Ghz with a vcore of 1.35 (i haven't tried to go lower)
On prime95 I blue screen after 12 min. Played games, used cinibench, sandra full benchmark multiple times etc and no blue screen.
I've upped the vcore to 1.75 in the hope that it would fix the blue screen but it still bluescreens on prime.
Temp in that run went up to 75 degrees celcius.

After settling on 4.9ghz I moved the uncore to 45 and memory is now using the xmp profile.

I can boot and run a cinibench on 5ghz no problem but seeing as I can't get the 4.9ghz stable on prime i just left it there.

I just downloaded aida64, so I'm going to give that a run and see what happens.

Okey I understand. Thank you for help. BTW: Intel Burn test, how should I setup it? Times to run tou said 20. That's okey, but what about stress level? is it enough standard, or should I set very high or maximum?

I think you meant VIN at 1,75. You could try 1.8 VIN and see if that helps. If that does not help, you may try to increase vcore by 0.01 and try again. Did you oc the cache also ?
