Is Overclockng worth doing?

1.25V is certainly more than you'll need, so I would recommend having a tinker and seeing how much lower you can get it. Lower voltages will reduce your running temperatures and reduce your power usage (leccy bills!), so it's worth seeing how low you can get it.

I would be very surprised if 1.25V doesn't get you stable at 4.2GHz, but don't forget to keep an eye on temps while the stress test runs as they creep up as your heatsink saturates with heat.
 
you need to learn to overclock using offset/dvid as this allows cpu to downclock itself at idle and switch to full speed at load

you only need tiny amounts of offset/dvid and each llc(loadline calibration) will add a further amount of voltage to the cpu depending on what level llc you use

check in cpu-z to see the load cpu voltage while stressing the cpu and use realtemp to monitor core temps and don't let them go above 80c

using auto voltage will usually overvolt/use too much cpu v,and a fixed cpu v wont allow the cpu to downclock itself at idle

for bios screen keep spamming the delete key as the splash screen whizzes past so fast

oh and to unlock dvid first set the cpu v to normal,you should just set it to normal for 4.2ghz you should be able to clock to that without adding voltage
 
Well it is up to you to decide....

Do you want an extra 10-40% performance out of your equipment for free at no major risk?

If yes then overclocking is worth doing. If no then leave your PC at stock.

Alternatively on the i series CPU's you could just use the Turbo mode and get a noob friendly 10% overclock.

My bios screen has disappeared when booting up. It just goes straight to my desktop.


Any ideas?

The post below yours contains good advice.

Download cpu-z so you can make sure your overclock has been applied correctly, and also so you can see what voltage is actually running through your chip.

When you load your cpu the voltage droops (referred to as vdroop) which can cause instability. Your motherboard has a setting to combat this called load line calibration (llc) and depending on the droop you experience you should choose a setting that gives you the closest load voltage value to what you set in the BIOS. That helps make things a bit more predictable. High LLC settings can cause big voltage spikes under load, which isn't ideal. Start with a lowish setting and see what voltage cpu-z reports while you run prime. If it's more than 0.02V above what you set, you can drop a setting. As long as it isn't below what you set then you can make overclocking a bit more consistent.

DVID (offset overclocking) adds an amounts to the default voltage while the chip is under load (when it needs it) and drops the voltage very low to save energy when your processor is idle. For your purposes this is the best option. If you decide to go extreme you may want to go fixed voltage to increase stability at your chip's limits. Add a few notches of offset and see what voltage you get in cpu-z. Over 1.35V is a bit dangerous so try to stay below that.
 
BIOS should come up. Try mashing the del key from the moment you turn on your pc. If it gets to windows then it hasn't worked. You may have disabled the splash screen, but you will still be able to get in.

Make sure your pc is completely shut down first btw. If it's just asleep it won't work.

It's not working. It was working before I installed my GPU a couple of weeks ago. It doesn't work now at all. Tried everything

take out your gpu,plug hdmi/dvi/vga into the motherboard and go into bios,set first initial display as peg or pcie save exit

power off and plug in your gpu,plug hdmi/dvi or vga into gpu and bootup should work then

it should auto detect it usually,but somethings up as its not displaying so try the above
 
right im in the middle of it and tbh im enjoying it. yes for my first time it is a melt but its fun.

i watched this video today...

https://www.youtube.com/watch?v=mBEeXajbG2o&list=UU_SN80_V2GymyCWM2oTYTeg&index=1

i followed step by step and taking the advice. im 28 minutes into it.

running my second test.

vcore set to 1.100 but on cpu-z its jumping from 1.100 to 1.126.

its sitting at 4.0 ghz my max temp is about 57.

any futher advice is welcome. :)
 
Can I join in? :)

Trying to OC the i5 3570K too but on an Asus P8Z77-V LX.

Noob question, is vcore the voltage? lol. I have it set at 4.2ghz and 1.180 voltage at the moment. After about 50 mins of BF3 on Ultra my highest temp according to coretemp was 54.

Is it worth pushing to 4.5, that's ultimately where I'd like to get to, don't want to go any higher. What's a stable voltage for 4.5? and when you guys are saying slowly bring it down until you find the limit what do you mean? Will the system not boot or crash or something? :D
 
I think you should read a proper guide as opposed to just randomly guessing voltages.... Get an understanding of what you are doing before messing about. Although you probably won't break anything you could damage it or shorten the lifespan quite easily if you put the wrong voltages too high etc.
 
its trail and error to be honest. i am going but thye youtube link and above and reading from the guys on here. it takes time. i have been at it from 5.30 today.

im now testing at 4.2 ghz @ 1.15v my highest temp is 64. fingers crossed :) im aiming for 4.5 ghz. i hear thats the G spot on the i5 3570k
