ok i try overclock my cpu using the asrock tuner software to 5ghz but suddenly blue screen appear (memory dump), after that my PC auto restart.

and i press delete to go inside the bios setup..then i see there is only 4.5ghz on oc tweak turbo ? why i cant oc 5ghz ? is it because of my mobo ?

voltage set to auto
PLL set as low as possible (1.3XX if i m not wrong)

then set to 4.8ghz and set 5.0ghz in axtu
correct me if i m wrong

What Vcore are you using? Don't say auto at 5Ghz. Too low Vcore = BSOD. Too much excessive Vcore = chip fried
If going above 4.2Ghz, better use manual or offset Vcore. Not all processors can exceed 4.8Ghz stable at any Vcore setting.

Do it slow, read up tutorials on overclocking Sandy Bridge/ Your board.

i know ppl dun recommend auto but auto do very accurate vcore for me
1.424v or 1.417, when i go below this, straight freeze of bsod

edit: i mean dun recommend auto sorry typo error

Make sure you do sufficient stress test too. Prime95 - blend tests for example. From my testing, sometimes BSOD comes within minutes, sometimes within 1 hr. sometimes calculation error, but no bsod


The tutorial i read up uses approx
4.5GHz @ 1.24v ~ 1.27v
4.7Ghz - 4.9GHz @ 1.35v

So, 5Ghz should need 1.4v+

where to set VCORE ? on the asrock tuner software ? or at bios ??

Not sure about that. But ASUS AI Tuner settings are temporary. The only way was to change settings in BIOS.
Software = test different voltages quick without rebooting. BIOS = changed settings here stays
Might be same for ASRock.

i still cant brain how to setup manually on bios any asrock user here help me please

vcore stand for ??? cant find vcore on the setup

sorry i mean in UEFI

vcore stand for what ? i cant find it on UEFI sorry for noob question

u find in cpu overclocking section, select load setting and choose 4.8ghz, then find vcore set auto, got a thing level 1,2,3,4,5, select level 5, PLL select lowest

i want setting for 5.0ghz

you cannot set 5.0ghz in asrock uefi
btw whats your cooling? you look like duno overclocking will increase production of heat

i think u better stay at 4.8ghz
go uefi and set to 4.8ghz voltage to auto and go to axtu and set to 5.0ghz

already set it on bios oc tweaker 4.8ghz...but it seems not stable...my Hz is changing2

= ='' you mean sometime it goes 1XXXmhz? its intel speedstep technology, if u wan see 4.8ghz stress ur proc with prime95

how to stress using prime95 if i using prime95 will it stay for 4.8ghz

the core no need to run at 4.8ghz when its idle, its not u wan to let it stay at 4.8ghz or not, its not nessery

how to test using prime95 ?

You should have done some reading about overclocking first before even thinking of buying your parts. You did the exact opposite and you lack a LOT of experience, too much to explain.

fark, prime95 not a tool to let you reach 4.8ghz,
this.

Go do a google search on how to overclock on your board.

Your processor.
Idle freq = 1.6Ghz
Turbo = You set Ghz

OC = lower stability, so to test for stability, have to stress it using programs like Prime95. Need to monitor temps, vcore, and whether the frequency can be maintained that high under stress.
Overclock to 5Ghz then browsing internet = no bsod = does not mean STABLE, need to see how it handles when under stress (eg prime95)


Overclocking is NOT overclock to 5Ghz, no BSOD. Done.
Overclocking is change settings, stress test, monitor temperatures/voltage.

It is usually not necessary to overclock too much. You risk reducing the lifespan of your processor, high heat + high electricity usage, instability.

SUMMARY:
Google how to overclock on your board + testing for stability
Google Prime95
Monitor temps using programs like HWMonitor + CPU-Z (for Frequency + Vcore reading)

Do it slowly, don't go 4.5Ghz -> 5Ghz straight away. Step by step 4.5 - 4.6 - 4.7...

When you overclock always do in small incremental and need a lot of patience. It may take days to reach the highest Ghz with stability which they run the Prime95 for 24 hrs. And doesn't mean that 1 system specification will have the same overclock with the another system with the same specs.

aiyark i already OCed at highest Ghz just now

Stable with how many hours of stress and max temp?

AIDA64 Extreme Edition too have a System Stability Test which you can monitor your temp, fans & voltages.

stable means no auto restart ?

Stable means no BSOD, auto restart, errors when put under at least 1 hr of stress test... go get prime95, do blend tests. Be aware of your temperatures.

i already run prime95 test without OCed and my temp is high to 60C

Normal la, under stress will be hot. What cooler are you using? OC must make sure stable under stress and temperatures stay within 70c/80c (up to you to decide the upper limit)

corsair h80 and im not satisfied ! later want to change WC if got more $$ so under stress without OCed also high temp ka ?? haiyo...how long shud i run this stress ? what is the main purpose for this test ??

To check max temperature and to see if stable when OCed. Length of test is up to you. I would say 30-60 or 90 minutes.
OC may be stable under light load, but when full load, it might become unstable. Prime95 tests the full load part.

then if i OCed and run the prime test there will be more hot??

Yes, and it can be quite a big amount when you exceed ~4.3Ghz

so it a waste i run the prime95 without OCed wah...not OCed yet also already 70C if OCed then 100 liao

This post has been edited by slap2begin: Apr 9 2012, 01:41 AM

This thread was about OCing. At least you know the temperatures of Non OC then can compare to with when OCed

You sure 3.4Ghz 70c using H80? I get ~66c using TX3 2600k @ 4.3Ghz.

This post has been edited by adbacc: Apr 9 2012, 01:43 AM

yeah bro h80 using small dot tuniq tx2 thermal paste arghhhh....wah... 4.3ghz already prime95 ? are you using aircond in ur room or what ?

Ambient temperature was 28c got ~66c prime95. Ambient 31c got ~71c prime95.
TX3 standard single fan full speed. Thermalfusion400 thermal paste

The temp are also being effected by your ambient temp. If you really wanna do OC , its not a 1 - 2 hours thing then you can settle. Just like other said , do it step by step. I suggest 2 hours of blend in Prime95 for each increment in Ghz. And of course , you need to always monitor the temps in each test and i'll say 80'C and below are good enough. You wont hit those temps in real scenario such as gaming etc. After you hit your desired OC frequency and able to finish the 2 hours test without any issues like BSOD , restarting etc. Continue the test for at least 12 hours minimum. If you didn't get any BSOD , error etc. That means your OC is good enough. But always remember to check the temps frequently. If it didn't go through the 12 hours minimum test , perhaps u should add more Vcore ( depends on the BSOD code ) etc , lower your OC frequency and try again. Haish , you should have asked around or do some reading on OC before you actually doing it. No offend , but it wouldn't hurt to learn isn't? Cheers.

right now my reading is 67-71 not OCed yet using full speed fan until my casing noise sound like jet

still like dat whats wrong ha ? btw how u know ur ambient temp ?

Ambient temperature was room temperature. Readings taken using thermometer in room.

woooo now my h80 radiator become so hot and the temp increase to 80C

Did you remove completely old thermal paste on both surface of CPU and cooler? Tuniq Tx-2 should able do the job.. What casing and airflow setup that you use?

yes already remove all the old thermal paste and apply a dot of tuniq tx-2 on my cpu...im using corsair graphite 600t ...my h80 using airflow pull and push inside the casing

Have you tried the airflow diagram as below. Blue for intake while red for outlets.


Attached thumbnail(s)

is that a standard airflow or i need to change the fan position ?

The most important part is front intake, top exhaust. Fans on H80 best to be installed blowing out immediately and not blown into the case.

This post has been edited by adbacc: Apr 9 2012, 08:16 PM

but right now im not putting the side panel yet did the air flow still important even im not putting the side panel ?

Try in closed case.

already closed with setting high speed rpm fan on h80 but the temp now is 40C-42C load only 5-10%

What were you expecting with idle temps? Blame ambient temperature + OC
Under normal conditions, OCing will also lead to higher idle voltages, which in turn lead to higher idle temperatures.

right now im not oc yet...haiyoo

Even so, 40c isn't a dangerous temperature.

i still wonder why my temp is so high...i already reapply thermal paste twice, i ask alot of ppl they said they also using h80 and the temp is 36-38 ...without airconditioner

Maybe your ambient temperature is 2c higher, so normal for your temperature to be 2c higher. Also, you may have stuff running in the background, using small amount of cpu (1-5%) which can also contribute to a little bit higher temperature.

what about the high speed level fan at h80 ...it seem like not function at all...

What does not function? RPM reading? Your fans are connected to mobo or power supply?

the fan is functioning well...the speed also working good...there have 3 speed on the h80 controller...but when i put it on the level 3 it seems the temp still dont want to change to low...its the same temp even i put it on the level 2

Don't worry so much on your idle temperature. As long as it isn't 50-70 for idle, it should be fine.

btw how i want to know my ram is running on 1600mhz ?

CPU-Z. Memory tab will show ~800 for DRAM Frequency = 1600Mhz

dram frequency only 532.2mhz..how to make it 800 ?

What ram are you using? If it has XMP 1600, go bios and load the XMP profile (not really sure how to do - check manual or do internet search)

corsair dominator1600mhz

Added on April 10, 2012, 12:43 amalready set it to xmp profile and it becomes 798.3 not 800

This post has been edited by slap2begin: Apr 10 2012, 12:43 AM

That near enough to 1600Mhz.

right now testing OC 4.4ghz using h80 and the temp on full load using prime95 is 80 C

normal ?

Load temp can be further reduced by lowering Vcore (can check current Vcore using CPU-Z).
Not sure how to manually lower Vcore on your mobo though.
But then too low Vcore - BSOD/crash/error
It's the delicate balance that makes OCing a headache.
