Need help with stress testing

[thunderdog512]

I'm over clocking for the first time and just set my 4770k to 4.2GHz using the built in option on the motherboard. Now I'm setting up my PC for a stress test but I'm not sure exactly which options I need to choose to stress my PC. Obviously CPU, I keep reading about FPU (not sure what that is though) so most likely that and I would think they mean CPU cache but i could be wrong. Plus, some people say AIDA64 doesn't stress as well as Prime95 but others say Prime95 is to hard on your CPU. I'm so confused.

Any input is appreciated.

Do not use Prime95, it's an awful stress test. It beats the crap out of your CPU and can cause issues with overvolting. Aida64 is a much better stress program, and the load is much more realistic. 

 

If you're still tuning the OC, run Aida64 for brief periods until you get to the clock speed you like, then run it for a longer period, keeping an eye on the temps. Running something like Firestrike Extreme and also help test CPU overclocks for gaming loads (as well as testing GPU a lot, but it's not needed.

Don't use prime95  on that CPU, apparently it screws with your voltages. Just use Aida64 CPU and FPU.

No stress test is "too hard" on your CPU. You want to push that thing as hard as possible when stress testing overclocks. That's the entire point of stress testing. You will be better able to test the stability of your overclock if you stress that thing as hard as it will go.

 

EDIT: Oh, apparently over-volting is a thing with prime95. Yeah, don't go that hard. Still hard. But not that hard.

[shypin]

you need to disable the option in your bios that feeds cpu extra voltage when the cpu needs

if you run prime95 with that setting on then it will harm your cpu

 

linus said that somewhere in one of his overclocking guide

read my cpu overclocking guide. the link is in my forum signature

You should be doing any and all CPU overclocking in the BIOS.

Software CPU overclocking tends to be unstable.

Loving the guide so far. Few questions, For the optimized defaults is that where you go the BIOS and just pick an overclock made by the motherboard manufacturer and restart? For the dirty overclock, do I just plug those numbers in and save? Will it be stable in my rig? I'm not looking to do any crazy overclocking just finally use what I payed for and learn some new stuff. Thanks for the help.

thanks!

 

no, the optimized defaults are the defaults that are set by the motherboard manufacturer and typically do not contain an overclock. just search and look for the option in your uefi/bios that allows you to set the motherboard settings to default and click apply, restart, and boot back in. you do this before making any changes.

 

the dirty overclock should be stable with most user's cpu's, but it's not a guarantee. i have no idea if it will be stable for you or not. you can try implementing the dirty overclock for now and then continue on the path to find the most efficient overclock settings going forward

 

i recommend you use the guide to it's fullest

what kind of motherboard do you have?

what kind of motherboard do you have?

An Z87 Asrock Extreme6

ok good. you should have the ability to set adaptive/static mode for your core, cache, vcore, and vring then. can you confirm this?

Here are two sites with pictures of the BIOS. I found two the things you asked about ( cache and Vcore) but the other stuff is labeled differently. It also says adaptive voltage or voltage offset. Sorry I'm not helping much. I'm definitely buying a different brand motherboard next time.

asrock is fine. thanks, ill take a look

your as rock motherboard is just fine. it's a good motherboard. better than gigabyte controls

 

look at the first image below. under oc tweaker > fivr configuration > cpu adaptive voltage > set this to adaptive when you've found your overclock and you are not stress testing; set it to static when you are stress testing

 

now look at the second image below. under oc tweaker > fivr configuration > cpu cache voltage mode > set this to adaptive when you've found your overclock and you are not stress testing; set it to static when you are stress testing

 

this is great! this means that you have full control over your voltages. gigabyte boards do NOT offer this

 

i'm going to add this to my guide. what options are you given when you select the following below?

 

cpu voltage mode

cpu adaptive voltage

 

cpu cache voltage mode

cpu cache adaptive voltage
