quick question, hopefully quick answer

[kanjo]

hey just put together my build. had a question though. 

 

running a 4790k stock (yes stock for the time being, will overclock down the road when i need more juice out of it ) 

so its at stock but be default it had adaptive voltage set and from what i see it is not wise to burn in test with prime95 while adaptive voltage is on for haswell cpus, being that this is devils canyon technically and not really a whole lot different i assume it will also not be a good idea. though if i want to have my cpu OCd later on is it wise to leave adaptive voltage on once i have figured out a stable OC to allow the cpu to clock back when not being used on high load, ie watching a movie or tv show on VLC or using chrome ect. or once is it the case that once i OC the cpu will always run at its oc speed eg 4.6ghz ?

 

as far as over clocking i will basically be doing more searching and using linus' guide for a similar system to my own which is this one >>> 

wondering if it would be smart to use the 5 ways optimization thing to get an idea of what the cpu will run at stable revert to stock and try running that overclock manually myself later. manually as i will have to see what kind of voltages it will try to put through as linus' and some other peoples OCs i have seen using that feature tend to be a bit high on the voltage side of things. any one have any input on this?

is there a set amount of time i should leave benchmarks/stress tests running and what are those times, some people leave them over night though that worries me as what if it heats up and fries itself during that time? i doubt RMA/Warranty covers that even on a K part... or does it? not sure. 
but at the same time i dont want to half ass my testing so yeah. any tips or advice is welcome. 

so far i have only ran furmark for about 10-15 minutes with everyone stock and it ran very well. fps count was high which is a plus. temps never went over 68 degrees for the gpu which was crazy considering it only ran at 68/69% fan speed the entire time (G1 gaming 970) and intelburntest on standard then high settings. both came back with stable results so that seems good. i hear it is not wise to run prime95 with adaptive voltage on as it may cause spikes. though i have no information on any other programs that should be avoided with adaptive voltage on. so if there are any please do let me know. 

 

i have aida64 but that stress test made me shit my pants because i cant use my nh-d15 yet. was testing the components prebuild with the stock cooler outside the case and cant find my isopropyl alcohol to clean the cpu off with so for the time being i am stuck with the stock cooler.....ugly bastard.

though with the stock cooler it easily reached 98 degrees so i stopped it real quick. 

so those are my questions. im sure they have been asked many times before but google is just more confusing because there is contradictory information everywhere. and searching the forum using google didnt really shed much answers for me either. so be patient with me peoples. i only need to be told how to do something once then i can basically go autopilot  



for reference my build is as follows, the noctua cooler as it is not installed. also waiting on noctua fans

case, NXZT H440 
mobo Asus maximus vii ranger 

cpu 4790k running stock for now

gpu gtx970 Gigabyte G1 Gaming running stock for now

ram 16gb g.skill tridents 2133mhz (waiting on ripjaws Z 2133mhz XMP profile active. 
cooler noctua nh-d15 

ssd samsung 840 evo 250gb

hdd WD BLUE 3.5' 1tb

psu EVGA supernova G2 850w (slightly overkill i noticed. but leaves room for sli later)

quick question with a wall of text................... didn't really read, but if your question is can you use the software oc to test stability when oced it's stupid since the software barely touches the clocks, it's reaaaally not even close to what you should aim for manually, so no go for manual oc immediatelly.

it happens to me a lot. i tend to over explain things but it gives people a clear image i guess. 

also that question was in there but i was focusing more on using it to find a "stable" OC to aim for once i start doing it manually. though i do not intend to do it now. maybe when i need a bit more kick out of the components down the road. 

 

mainly my question is, should i leave adaptive voltage off. and if so do i completely lose the ability for the cpu to slow its clock speed down. though i get the feeling that wont have jack shit to do with it given that the multiplyers are basically what decided an oc. can you OC and have the cpu clock down when not under load or is it once OC its running at full tilt the entire time until you stop the OC?

also. is aida64 supposed to make me shit my pants. i know it was just the stock cooler but jesus it sprinted to 98 degrees and i am not willing to let it sit there for the test. doesnt seem like a good idea.

If you see my post on the 4790k and prime 95 I had temp comparison between intel extreme tuning utility, Adia 64 and Prime 95. (prime 95 almost got my cpu up to 95c)  It overvolts the CPU some how. 

 

Prime 95 should not be used at all. 

 

Software OC is mostly just a waste of time. They usually don't work to well. They might increase the 4790k to 4.5 ghz but it will get you  a lot of heat. Most software OC uses the multiplier overclocking not North bridge oc(which gets more performance)  

[i_build_nanosuits]

you can swing to manual voltages for testing your overclock (i suggest using intel extreme utility for stress testing and monitoring, you can use this software even with adaptative voltages if you prefer it won't overvolt your CPU)

and once your complete and stable you re-activate the haswell porwer saving features like so:

 

Haswell Low Power Modes

 

 

•Cpu ratio mode- Dynamic

 

•Enhanced Turbo- Enabled

 

•CPU core voltage mode- Adaptive

 

•CPU ring voltage mode- Adaptive

 

•Intel C-state – Enabled

 

•C1E Support- Enabled

 

•Package C-state limit - Auto

 

for windows users also make sure you set your minimum processor state to 5%

 

 

Windows7

 

->Control Panel\All Control Panel Items\Power Options\Edit Plan Settings

 

-->Change Advanced Power settings

 

--->Processor Power Management

 

---->Minimmum Processor state

 

-on battery 5%

 

-plugged in 5%

this i have gathered so far. but it could be used as a quick dirty way for me as a noob to find a good clock speed and then work the voltage down to see if it remains stable. though that seems dangerous. better to do it manually i suppose and work up slowly

just to make sure i will have to make sure adaptive voltage is set to on in the bios also for those settings to take effect or will they override that once i set them in windows CP?

 

This might help you out.

thanks that did re-enforce what i have heard about prime95. will try the intel stress test and see how i go. though i want the cooler installed before i do any cpu stress testing/burn ins 

 

 

--edit--

hadn't realized the intel stress test was just another name for the intel burn test app. i do have that and i have ran that for the cpu even with the stock cooler and got stable for the results on standard and high. did not want to push it too hard with the stock cooler though. will try more once the d15 is installed. any other recommendations. should i try cinebench also or not really needed?

i recommend you do the entire overlcocking process from your UEFI (BIOS) and not rely on softwares for that.

will be doing that. though that will be some time down the road. the parts have plenty of guts now to power what i need. will leave OCing for later in the life of the pc to squeeze some extra life and power out of it. then if all else fails upgrade/sli. 

 

just want to get all the information in one place so i have a reference to check back to and not have to do this later. better to get it cemented in now so it will be recalled easier down the line.

that's the good way of looking at it i must say...your CPU run's at 4ghz and 4.4ghz boost out of the box already...it's plenty fast IMHO.

yeah it is plenty powerful for what i need now and in general so overclocking later in the life of it will give me a slight upgrade without having to upgrade my cpu. unless things change like these processors are somehow obsolete in less than 2 years. though i am kinda bymped. one of my noctua nf-f12 fans (black industrial) was a DOA. powered on and just did nothing.. gotta get it replaced now. other than that all seems well.
