Want to oc my core i5 lynfield

[dal]

Hi all, I want to overclock my core i5 lynfield a bit more than what it is already, but I don't anything about overclocking except clock x multiplier = speed. I'm currently running at 3.2 (160 x 20), so all I've done is changed the base clock speed, no voltages have been changed as I don't really know what I'm doing when it comes to voltages & timings etc.
I've ran prime 95 on it for 10 minutes & my highest temp in one of my cores was 73 according to CPUID HW monitor. I did try going to 3.3 but I got a warning coming from case speaker (can only assume it was cpu alarm), I cant tell you what the temp was as didn't have any monitoring software installed at the time.
So if you don't mind what would be my next step.


Thanks.

Edit : If I could get to around 3.7 I'd be happy with that

Most of these will do 4-4.2ghz with ease

These are fine right up to about 1.50 volts despite the recommended max being 1.4 but stay at 1.4 or less for now as the tuniq may not be able to keep it under 85 c full load

Just try 200 fsb
1.375 vcore
1.39 chipset
make sure memory ratio is set so the ram is at 1608mhz
set memory performance to standard

My old pc had an i5 760 that I overclocked to 3.8 with ease.

Cheers I'll have to try it tomorrow now got to go to work soon

I have a similar board gigabyte p55 ud4 and i5 750 i'll post screens of my bios settings later.
Your cpu will probably do 4ghz 1.4 ish volts easy and the tuniq tower is still a bit of a beast cooling wise, have you ever cable tied another fan to it ? might drop 5c load temps doing that on a tuniq as it just has the middle fan I owned one years ago.

I would recommend getting asus real bench for stability testing and cpu-z to monitor vcore etc, hwmonitor is good for temps and which games do you have ? run some games too I find left4dead arma III an unstable overclock falls down fast, also intel burntest can save time finding stability but the tuniq tower might not be good enough to keep it lower than 85c under intel burn test why I mention cable tying an additional 120mm fan to it.

Plus you may as well overclock with adaptive/dynamic voltage as it down clocks the voltage when windows down clocks the multiplier when it's idle.

I had to move from 1.38 to 1.4v when I increased memory from 8GB to 16GB but my chip has been at 4GHz for about 6 years now (2009 wasn't it?)

Going over 4GHz the voltage requirement went through the roof.

I have a maximus gene so the bios will be different but ill have a look at it later.

Cheers guys, looking forward to having a tinker with it tomorrow. Not tried any other cooling solution as I've never overclocked it much .

They overclock well on just stock voltage. On mine I had it running at 3.7 and undervolted to 1.25! The machine has now been rebuilt into a HTPC, and it's running stock at under 1.1v! The default CPU voltage of 1.3 is overkill for its stock speed.

Ok done this, booted into windows no problem, I started prime 95 & 2 of my cores got a error within seconds. I continued running & my highest temp was 86 but I only ran for 5 mins as only 2 tests were running.
It's around 58 idle.

Here's some photos of my bios settings, can you confirm I've set them as suggested.

Im I right in thinking QPI / VTT is the chipset voltage.


EDIT : Just dropped the clock speed to 190 & ran prime 95, no errors but had a max temp of 99 within 5 minutes so increased the fan speed on my cooler & max temp after that was 96. Id' be happy to run at 3.8, could I drop the voltages a bit @ 3.8 ?

Spoiler

 

[Hotwired]

Maximus III Gene + 750 @ 4GHz + 16GB @ 2000MHz

Ratio = 20.0
CPU = 1.4v
PLL = 1.802v
IMC = 1.219v
PCH = 1.06v
DRAM = 1.656225v


*edit: 99 degrees?

Please invest in something better than the stock cooler before you fry your chip.

**edit: appears you're using a Tuniq Tower Extreme, temps still seem excessive. Your BIOS says you're IDLING at 55 degrees...

Check your cooler is mounted properly and redo the thermal paste?


For reference:

My cpu with higher voltage is idling at 40 degrees in a 25 degree(!) room

And 5 mins in Prime95 takes it to 70 degrees: http://s9.postimg.org/svfut0jf1/temp.png

Load line calibration should be set to enabled heres my settings set your clock drive to 800mv like mine

Your cpu should not be hitting anywhere near 90 something is wrong and you should STOP and start on a lower voltage
Also I'd recommend double checking your cpu seating / fan settings as 55c idle something is up turn off all that bios cpu fan setting stuff and have the fan running at max

say 1.30 volts but keep the chipset voltage at 1.39 just to eliminate it and make sure your memory voltage is at 1.65 or 1.66 volts with the correct timings which they rated at for 1600mhz

when stress testing run the fan at max check your fan settings in the bios disable smart fan controls so the fan run max for stress testing the tuniq comes with a fan controller
so use that and turn off all motherboard controls over the fan you can sort all that out later

Only have your fan running max and try to cable tie another fan if you have it to tuniq tower so you have 2 fans pushing same direction
Use asus real bench and games to stress test and keep an eye on temps I am not sure a single fanned tuniq is up to keeping it at safe temps on programs like intel burn test.

Anything 85c or less under such extreme stress apps can be okay as long as that's the peak temp but 80c or less is more desirable.

Gaming temps anything 75c or less is fine mine peaks at about 60c gaming on a noctua d14 with 2x140mm fans so the tuniq will probably be 70-75c.
But temps depend on how much vcore you're using.

Start at 1.3 volts say 3.8 ghz and see what temps are like under asus real bench anything not over 80c is fine as actual gaming temps tend to be 10c lower than stress testers and up to 20c lower than apps like intel burn test.

I have UD4 and some people say clocks better if you set 800mv cpu clock drive so set mine there and for sure set vtt voltage to at least 1.35v the higher clocks tend to need 1.375-1.4 volts chipset

I thought my temp software (CPUID HW monitor)may be reporting wrong temps so I downloaded RealTemp 3.70

Then done another test without changing anything (although I did change my graphics card & I suspect my old one produced more heat than my new one)

5 mins in prime 95 gave me max temp of 86, but after 10 mins got max temp of 92.(CPUID and realtemp readings were mostly with 3 degrees of each other)


Then I changed the following :

Load line calibration set to enabled
CPU clock drive set to 800 mv
CPU vcore set to 1.3

5 mins in prime 95 gave me max temp of 92, after another 1.5 minutes my temp was at 95 max so ended the test there.

So it does seem my cooling isn't up to the job. Next on the list is get some more thermal paste, remove tower & clean with compressed air, clean air intake fan in tower & reseat tower. I'll retest when done & if I still get highish temps I'll either get another fan as suggested or I might even look at watercooling if I can get a basic setup for not too much money.

Personally I would not be increasing volts and especially if your not running a very good cooler.

What I would do is keep nudging the multiplier up and testing until you find a temp your happy with. Once you are stable on a clock / voltage I would then start to reduce (under-volt) the CPU voltage, this then brings your temps down but keeps the over-clock. All this takes time to-do, and should be setup over a number of days making small changes at a time.

Before doing any of this I would put the memory multiplier low, if your overlocking RAM at the same time as overclocking CPU, when something fails you won't know if it's CPU or memory.

IC Diamond paste I have found best.

Yes stop because 92c for prime is way too much and you're in danger of damaging the chip

A tuniq tower with an additional fan cable tied to it should be able to achieve under 80c prime.

Something is still up though imo because 92c on a tuniq with its fan going at max still sounds like something else is causing such a high temp at just 1.3 volts

either the fan is running on low or you have a bad contact with heatsink and cpu

 

[dal]

I will be removing tower & blasting with compressed air as its never really had a good Clean, I remember a graphics card I had once used to get hot quick basically it had so much dust in it it effectively had a fur coat on, if was much better after cleaning. I'll post back when done

 

[dal]

Well I've removed mobo, removed cooler & took fan out & it soon became clear why my temps were high....




So gave the fins & fan a hoover & blast of compressed air, blasted around the cpu & fitted back together :
Now after 10 mins of prime 95 my max temp is 78 as opposed to high 90's

Also when I removed the heatsink from the CPU it came away with no resistance whatsoever so I'm wondering if I'd put enough thermal paste on it the first time round.

 

[C64]

Just put a small amount in the middle of the cpu like a grain of rice or slightly less and let the heatsink spread it over time.All that reallyu needs to be making contact is the center anyway.

 

[C64]

I must say I think these gigabyte boards like 1.4 volts VTT to get higher clocks.
I am currently 1.4 vtt and 1.4 volts vcore (adaptive) 20x 205 mhz = 4.1ghz If I lower to 1.39 vtt it's unstable and takes 1.46 volts cpu vcore to be stable.

I think if you cable tied another fan or two new fans on that tuniq you could bring the temps down much further.

 

[dal]

I'm happy to run at 3.8 with those temps. May say my fan sounds a bit.louder now
