Voltage Stability Testing?

[UnaverageVague]

okay so I ran AIDA64 for 20 minutes at a 1.200v for a 4.8ghz OC on my i7-7700k and got no crashes everything was great

 

but the second I started loading up apps and stuff or installing a game I get a BSOD why did this happen doing installs and stuff and not on the AIDA test? also I only had the CPU checked on the AIDA test

Check FPU as well, aida isn't the best stress test in the world

Check CPU, FPU, and Cache for a stability test, this will hit the CPU harder than just having CPU checked. Try to test with that and see if AIDA crashes out

ill give that a shot and do you guys recommend any other type of stress tests that are better?

PRIME95 is the end all be all as far as I know to really stress testing, but I personally wouldnt recommend it as it puts a load on the CPU thats very unrealistic, even for a synthetic stress test. If you pass AIDA you'll be fine for the most part.

Realbench for 2hr is a good test.  Prime95 and OCCT for 2 hrs each if you want to be even more thorough.

ur OC is bad....no proper stress tests

still better than stock tho

mmmm..... a working pc at stock OR one that crashes under load?  The OP just needs to redo his OC better....and yes a good OC is better than stock but stock is better than bad OC

Remember that an OC that fails under artificial stress-testing might be perfectly fine for gaming and that the opposite can also be true - you pass all the synthetic things but fail in real world conditions. You might also want to make sure that your PSU isn't being overdrawn/having issues.

if I set the OC to 1.235v it runs 100% fine but I never went below that other than 1.200 and that was a fail im trying to get the lowest voltage for 4.8 to get the best temps not really worrying about going any higher than 4.8

all cpu vary in OC ability...its just a cases of finding ur best happy medium....I run prime 95 for my OC's for about 2 hrs

I've been doing some research a lot of people are saying AIDA64 can take up to 6 hours to find a instability in the system that may explain why I passed with flying colors, I'll try real bench out and see what that gives me

yep stress testing s/ware varies , ive always found prime95 good , thou some say it can be to hard on pc,s but ive never had an issue with it. plus as an earlier poster correctly stated "Remember that an OC that fails under artificial stress-testing might be perfectly fine for gaming and that the opposite can also be true - you pass all the synthetic things but fail in real world conditions." the first part of this premis is true , we want it to pass not fail. that way we know it will work in real world. while this didn't happen for you, its most likely down to stress s/ware

I've always stressed with prime, recently I've added aida as well. Different stress tests work differently, good to have a mix

 

Good thing is prime is pretty diabolical for heat, good to test cooling under worst case

gotta agree , baddest stress test s/ware available that does the job. so once you pass this mother , reality is a cool breeze

Now after I have achieved my ideal OC do I switch from voltage "Manual" to "Adaptive"? Cause I know what adaptive does but I don't know how to set offsets and stuff like that

Adaptive will up the voltage to give you more overhead where needed and is generally fine provided you aren't near your maximum safe voltages (since some motherboards will not stop there and will keep giving voltage even if it would fry the CPU).

 

And, personally I'm a fan of 3DMark's looped stress test for checking overclocks. It might not be the most intense synthetic but it emulates gaming fairly well and also loads the GPU.
