PC not starting after overclocking CPU

Ambulas · Sep 16, 2016

Hello everyone, i overclocked bro's pc
CPU - AMD FX 6300
PSU - CX650M
And an aftermarket cooler DeepCool 400
Overclocked a CPU to 4.3 ghz

At first not touching voltage everything boot up, and monitor show blue screen of death service system exception

After disabling/enabling settings setting mhz, i set voltage same like someone in video did (with same overclock)

Now trying to boot up pc all lights lit, no beep, monitor doesnt show anything.

Please help.

Every chip is different, copying someone else's settings won't necessarily work for your chip and motherboard.

Reset the CMOS to default and hope your failed overclock didn't fry anything.

I reseted CMOS windows boot up, everythings fine.
If every chip is different then how can i overclock my cpu

im not tech savy

If you're not tech savvy then you should reconsider overclocking. Like he said every CPU is different, you can't just take someones settings and run with it. There are lots of guides that can take you through the process if you want to learn, but we can't just give you the answers you seek, and someone who does, is doing you no favors as bad settings can fry your CPU.

If you want to start reading about it I recommend studying this document first

This is exactly why I discourage overclocking!

Can you help me with overclocking ?

My dad specially bought new psu and cooler just to overclock and how now i can say to him that i can't overclock it

Rogue Leader · Sep 16, 2016

Read the guide i linked. And then try it, SLOWLY. Turn it up a little, then test, then turn it up a little more then test.

Once you have learned a bit about it, then come back here and ask questions if you have any.

Turn up what turn up where turn up how much...

Rogue Leader :

Also, is it safe to use AMD Overdrive ?

Rogue Leader :

Hi please help i did overclock by that guide but i got blue screen of death service_system_exception

Rogue Leader · Sep 16, 2016

AMD Overdrive is the best way to test overclock settings with an AMD processor.

If you got a blue sceeen of death then you overclocked it too much.

Go back to the guide and small steps.

4.3 ghz is too much to start.

Rogue Leader :

How you knew that i set it to 4.3 ghz

but if not 4.3 then what to do ? like setting it to 4.0 is bit low

Rogue Leader :

I set it to 4ghz and omg difference in fps is so huge, i just want to know, why some people can do it to 4.3 without changing voltage and i can't dont it.

?

What is your motherboard model ??

That is going to be the biggest difference by a long long way .

I've never seen a 6300 that won't hit 4.3ghz easily.

The difference between boards is also the difference between voltages required to do so.

A good 10 phase board like the gigabyte ud3p I've had chips overclocked by 700-800mhz at less than stock voltage.
On a 4+1 phase board that same overclock can require a huge voltage jump because the regulation is nowhere near as good.

madmatt30 :

Motherboard is MSI 760GM-P23

Now pc keeps restarting and showing service_system_exception

madmatt30 · Sep 16, 2016

The board is entirely your issue then.
That board is not suited to overclocking at all really.
3+1 phase & MSI always used cheap MOSFETs back in the day.
I wouldn't push past 3.8ghz on it personally , if you've got 4ghz stable leave it & be happy.

Those black chokes behind the cpu are what regulate voltage , they run incredibly hot & a tower cooler like the gammaxx offers no cooling over them whatsoever.

madmatt30 :

Omg then what motherboard should i get ?

Rogue Leader · Sep 16, 2016

Ambulas :

Because thats what you tried before, and I knew that you didn't listen to what I had said.

Madmatt is right, that motherboard is not for overclocking, and I should have asked this earlier. You're not going to be able to overclock well at all on that board. As he said as well your tower cooler while help the processor makes it even worse for overclocking.

You need to get yourself a 970 or 990FX based motherboard with an 8+2 power phase. For example the ASUS 970 GAMING/AURA.
