overclocking stability test

[ravihadz]

greetings everyone!!!

 

this is my first overclock so i needed some advice and guidance!! Ive overclocked 4770k @ 4.5 ghz @ 1.27v (on msi mpower max mother board) and corsair vengeance (8x2) 16 gb ram to 1866mhz @ 1.65v. I need to know weather this overclock is stable?? plus are these voltages safe (1.27v)?? I ran the aida64 stress test the temps were at all time below 80 degrees (But i didnt run the test for long)!!!

 

What are the other stability tests that i can run? plus how long should i ideally run them?

 

(Attaching a print screen of cpuid)

 

Thank You

(Suggestions and Advices are welcome!!)

I'd recommend you to run Prime95 for at least 12 hours (24 hours would be best) to make sure your PC stays stable on those clock speeds. 

[mvitkun]

run prime95 small fft for minimum of 4 hours,the longer the better.

prime 95 64 bit

[Slater]

Would prime95 be enough though? Haswell has some new instruction sets that are supported by Aida64. Has prime been updated to stress those as well?

Prime 95 is not recommended for haswell, because of voltage regulation changes, run AIDA for 12 hours, if it does not fail, your cpu should be safe, i think TTL said OCCT is a good tool as well, so try that, if you have a constant 1.27 voltage you should be safe with prime, but if you use other settings, Prime could cause your CPU to have voltage spikes, and that might damage your CPU, i recommend 12 hours of testing minimum for any test program, Linus even said time and time again 24-48 hours of Prime means your CPU i safe, that is kinda too long for me, but the longer you test, the more sure you are that your overclock is safe, as i have read, he intel k series 1155/1150 can all go 4 ghz on all 4 cores with stock voltage, but after that you must increase voltages.

 

Try testing your cpu on less voltage, because 4.6 overclock is a goal when you get to 1.27V so try bumping it up, if you are satisfied with 4.5 decrease voltages, oc is not just adjust voltages and find clock, it's about the lowest voltage you can have at given clock, that should be your goal, and i hope you have a good cooling solution for 1.3 territory, because your chip will run super hot

hi!! i stopped sunning prime as soon as i found the issues with it and haswell!! i was running 1.27v on adaptive settings.. but now I've toned it down to 1.265v and clocked it at 4.4 ghz.. the reason: every time i run aida64 stress test i get an CPU THROTTLING  - OVERHEATING DETECTED   msg at the top !! when i check the voltage it runs high at 1.36v area(due to adaptive settings).. (max temp always around 87 to 88 degrees).. i am using an NZXT kraken x60 (140mm all in one liquid cooler). what do u suggest ?? i know the tests run unrealistic stress scenarios but i would still like to be safe!!

With Haswell you want to find the voltage that the CPU is stable (at a given multiplier) by first using the Manual voltage. Run whatever stress test you want, AIDA is good as it's uses/tests all Haswell instruction sets and is more indicative of real world use. Passmark and PCmark do similar. Prime95 isn't so comprehensive in testing all instruction sets, and therefore the whole CPU, but you can use Prime (while using Manual voltage) to gauge system stability. If your going to use Prime then run it for at least 17.5 hours (twice that if possible). Prime goes through a number of FFT lengths (70 x 15min each) when stressing the CPU, some have a tendency to crash the system while others won't. It's also possible they'll update Prime soon so that has better compatibility with Haswell, but it'll probably (might?) still have the voltage spiking problems when using Adaptive settings.

Once you know at what voltage your CPU is stable (stress testing using the Manual mode) you can play around with Adaptive settings so that when the CPU is underload the voltage equal to that of when you set it manually.

heres what i would suggest. I am not using prime 95 for stress testing haswell.

Hi mate, glad to help if i can, so here is the deal, you MUST NOT test haswell CPU with adaptive voltage regulation, the procedure is this:

1. Go to Bios and set voltage setting to manual

2. input voltage required, and clock speed you want

3. save and exit, go to windows

3. Use Aida 64 test and run it on that setting, and if it stays stable for at least 12 hours ( my recommendation, feel free to test longer )

4. If the test passed go back to the bios and set voltage to adaptive.

5. save and exit, you are done.

 

Now, about that voltage thing, adaptive mode is used to save power when cpu is idling, so it will decrease and increase dynamically, if it was me ( i do not require an intel CPU over 4.2 ghz, because gains are not that massive after that, and you get a lot of heat, and power draw from your cpu, that cpu still uses less power than AMD equivalent on manual voltage anyway , not to mention i turn my PC off when i am not using it so he is never idling anyway ) i would never use adaptive, i would try to stay at 1.1- 1.15 V and get a stable overclock on that, and leave it on manual.

 

If you need more info please watch Linuses Haswell OC video, multiple times if you have to, he covered all of this to a greater detail

Hi as suggested I ran the test(aida64) for about 20 hrs! No problem everything was ok. No overheating no throttle! How ever when I restarted my PC earlier this evening it just crashed and didn't boot up. I had to go to the bios and switch to default settings... I had overclocked CPU to 4.4 ring speed 4.1 I have and xmp ram 1866mhz which I had enabled... what am I doing wrong? Now I am trying to load the overclock profile that I saved earlier as it worked...it does not work! Need help!

[ProKoN]

try putting your ring bus at 3900MHz and the voltage set to adaptive?

 

what bios version are you on?

 

maybe slightly increase your bclk or decrease it ex. 100.5 or 95.5.

[Morfy]

That RAM voltage seems fishy, waaaay to much if it's a 1.5 v kit.

[ravihadz]

when ever i start with default settings and enable xmp mode  it shows 1866mhz @ 1.5v but when i save and restart the pc ! it wont boot just doesnt work.

am using msi mpower max motherboard the bios is upto date and so are all the other drivers (except one DIRECT OC it seems the website has a broken link and i cant download it any where) the motherboard also has on board one touch over clocking buttons which do not work as well!! it will not boot up if i use the over clock button!

even if i keep all the other settings at default i cant seem to run my ram on 1866mhz which it is supposed to. ive tried over clocking from bios, on board buttons, os softwares but failed!! please help!

[ProKoN]

put your ram at 1333 and 1.5v. dont use xmp, try that. im on bios v1.1. seems to work fine but some issues past 4.8GHz.

drivers can be found here.

http://www.msi.com/product/mb/Z87-MPOWER-MAX.html#/?div=Utility

keep your ram at 1333 and try to bring up the multiplier and voltage.

also try setting the cpu ring bus voltage mode to override

leave the cpu ring bus  voltage set to auto

do not install the direct oc utility it is BS

[ProKoN]

you could always try to boot into the second bios and overclocking from there

[Opsilon]

Well if non of this helped, dude you might have a bad chip, try 1333 with an 4 ghz overclock only, see if that works and then try going up, test ONLY on manual voltage, adaptive is not for testing!!

when that finishes, take your ram and put xmp, and redo the test, you will see the if you have a safe overclock, if not, try testing your ram, the sticks might be broken...

[ravihadz]

I seem to get stable over clocks @ 4.5ghz but as soon as I play around with ram it stops working.. the ram works @ 1600mhz. If the ram sticks are damaged how can I check it? Plus how much of a difference performance wise will it make? I do a lot of heavy excel work that includes macros with high number of iterations plus a bit of videos editing and a few games in free time.

[ravihadz]

Plus could my Psu be the problem? It's a corsair cx750m 80 bronze!

What is a [TRIAL VERSiON] motherboard? You should run your stress test for at least twelve hours and AIDA64 is perfect to do stress testing with but you can run OCCT if you want a different stress tester. Also, if you find your voltage is too high then try carrying the voltage down via offset if your motherboard supports it.
