CPU/RAM OC

CC1300 · 21 Aug 2020 at 23:17

Hello everyone! I'm trying to push my old system for more as I cannot afford a big upgrade yet. I am new to overclocking and although I have watched various tutorials over the internet I have bumped into some issues.

First, I have an asrock z77 as mobo so I have overcloking options enabled in bios. I have tried to overclock my i5 3750k to 4.2 ghz, but unfortunately every time my windows loads I get system errors and my PC crashes. I have lowered it to 4.0 ghz and it seems to work fine. I was wondering what the problem could be? I have seen that this particular CPU can go up to 4.4 ghz. I have a cooler master 212 RGB black and temperature is not an issue as my cpu at 4.0 ghz always keeps to 35 - 45 degrees on idle and 60 - 80 when gaming.

Second, I have 16GB of HyperX Fury 1866MHz. I wanted to overclock this to 2200 MHz, but everytime I try it my windows does not even load. I have seen suggestions that I have to pull the mobo battery out. I have took it out for half an hour and tried pushing the RAM to 2200 mhz but still the same issue. What am I doing wrong?

Also, do you think it is even worth to try to oc the RAM? I have seen contrasting opinions on this.

Thank you in advance!

Hi, I left it on auto. What voltage should i put for 4.2 ghz?

I use cpuid to monitor and voltage plays between 1.1 - 1.321

Set it to 1.3 and see how you get on, up to 1.35v should be fine but keep an eye on temps though as you don't want to be going much above 80c.

Maybe take the cooler off and re-paste if this hasn't been done in a few years.

I have actually re pasted my CPU yesterday with arctic. I have tried to look for CPU voltage or Vcore voltage, but i cannot seem to find it? Which one of these options is it?

Just overclock the cpu first leave the ram.

will do that, thanks

Make sure all power saving options are disaBled and set load line cal to 3.

Does your motherboard have auto oc profiles, my arsrock did.

Try them.

Yes, im running one of those profiles at 4.0 ghz, and tried to do the same with the 4.2ghz. I will set load line to 3; power saving is also disabled. how about the voltage?

Increase it slightly then test checking temps also.

Yes but i do not understand how, if you check the images i put there is no option for cpu/vcore voltage.

Change cpu voltage to fixed and then you should have more options

There is no option for that. There is only Cpu voltage offset; also i cannot set load line to 3 (options available: auto, 0% 50% and 100%) ive tried playing with all options in the picture, there is literally no option to modify the cpu voltage; only additional turbo voltage?

What model is you motherboard, have checked the manual .

AsRock z77 pro4, i will check online for manual

After some googling It seems that the only option to overclock on your motherboard is offset voltages.

i was looking actually at the same thing plus this video

https://www.youtube.com/watch?v=DfVwP_Cw6Gs

and this

https://www.overclock.net/forum/5-i...-sandy-bridge-ivy-bridge-asrock-edition.html#

I have updated bios and some drivers and i have used these settings:

All core: 42
Spread spectrum:disabled
additional turbo voltage offset: +0.078V
Long duration power limit: 300
Short duration power limit: 300
primary plane current limit: 300
secondary plane current limit: 300
Cpu voltage power: offset: -0.010V
Cpu load-line callibration : 50% (i suppose this is lvl 3?)

No crashes until now, running idle at 30 degrees. Do you think i can push it to 4.4ghz with the same settings? The guy in the video oc'ed it to 4.6ghz but im afraid not to implode my chip.

Keep on temps at max load go as high as you feel comfortable .

Once you have stressed tested your overclock take notes of temps to compare.

So I have downloaded Prime95 and I have started running the recommended stress test, CPU has been running at full 4.2 ghz for some time now with temp at 70 C. I will leave it for an hour to see what happens. If temp will stay constant 70-80C at 4.2, do you think I could increase to 4.4?

Go for 4.3 next but I wouldn't want my temps going over 75c max.

Cheers, will try that and come back later with the results.

Tried 4.4ghz, computer did not boot, then downgraded to 4.3ghz, which worked for a while but it crashed, then it crashed again. I've put it back to 4.2ghz, i'm not sure if I can do anything else.

4.3 add a bit more voltage check temps

Increase the turbo offset by how much do you reckon? it's at +0.078V

Also, according to CPUID the voltage has reached 1.381V in some periods. Is that safe?

The absolute maximum vcore voltage recommended by Intel is 1.4 V, so I'd recommend staying under that for everyday use.

So you have a choice push higher if so increse voltage in increments till stable or stay at 4.2 , I would stay at 4.2 and try to lower the voltage .
Test and check temps keep reducing till you fund the lowest stable voltage.

Then tackle the ram check the xmp profile and set it

There may be others that have more knowledge than me that can help you achieve higher clocks.

CPU is stable at 4.2ghz, temp does not go over 65 even when gaming.

In terms of RAM, i don't know what I'm doing wrong. Whatever i try, computer does not boot.

Firstly what is your ram speed?
There should be a setting called xmp profile change that to the next available speed, it mite say profile 1 or 2 .

Try profile 1 as 2 being the most extreme

Hey, sorry for the delay, been busy these days.

So my Ram is furyX 1866hz, from what ive seen online people oced this to 2200-2400. However, whatever I do computer does not boot afterwards.

I do not have a thing called xmp profile anywhere in bios, I have looked everywhere. Anything else I can do ? Thanks

mickyflinn said:
Did you find the xmp profile ?

Nope, I do not think my mobo has those. The only thing i can do is change the MHz and timings. mobo is so old i cant do anything in it; i might just give up

I remember when I tried it was a pain, I could only get a small increase.

Best to use an overclocking guide and then it's trial and error

Sorry I can't help you further, good luck.

Yeah, I figured it is something like that; problem is whatever i try the computer just refuses to boot. I do not think anymore its worth the time. Thanks for the help anyway!
