Increasing CPU Voltage help

Hello

Recently I bought a new PC with the following specs:

CPU: Intel i7 2600K Over Clocked @4.5
CPU Cooling: ThermalTake Frio
MB: Asus p8z68 v pro
RAM: 8Gb 1600mhz corsair ram
HD: 2x 120 GB Corsair Force Series 3 SATA III Gaming MLC Solid State Raid 0
HD2: 1TB Sata III 7200RPM for data drive
GPU: Nvidia GTX 580 1.5gb
PSU: Corsair 1050 Watts HX1050W


I have been getting Issues apon boot up where the PC would turn itself off after a few seconds of pressing the power button. After phoning tech support and giving them the blue screen error code they have got back to me saying that it is being caused buy the CPU not having enough voltage and they want me to "increase it by a few notches" (There words not mine) they really haven't been very helpful In directing me on how to do this. So I was hoping to get some advice?

I have entered the bios (Asus EFI Bios Utility) but can see nowhere to Increase the CPU voltage?

Also I have heard Increasing the CPU voltage can be very dangerous to the CPU lifespan and computer itself? Should I trust the tech support and go for it or look into other options?

Thanks
Matt.

 

How did you OC the 2600K? Did you take the 'dummy route' which should have easily gotten you to 4.3GHz, at least that's what mine did. After that it's trial and error, I hate to say 'try this voltage' so I won't post one as I don't want to be the one responsible for blowing up your machine.

Go into BIOS and increase the voltage by the minimum and then test for stability using Prime 95 or equivalent. You have quality components in there so I see no issues. Why the heck you want to OC that machine is beyond me.:confused

 

Hi

The Pc actually came to me over clocked, I did not Overclock It myself So Im not sure what route they took. I have never overclocked myself so am Not sure how to Increase the voltage to the CPU.

I entered Bios (Its the ASUS EFI Bios utility) But couldnt see anywhere to actually change the voltage? Is anyone familiar with the Asus Bios utility and can point me In the right direction of how to change the voltage??

 

Why don't you just go into BIOS and set to default, F5 I believe since you didn't start the OC, it's best that one doesn't trust someone else's OC. I wouldn't. Let us know what happens at default settings.:major

Edit: If you wish to OC after this, take it one step at a time and research as much as you can. Still the Sandy doesn't need to be OC'd, damn fast cpu!

 

Hi again

Thanks for the advice Augiedoggie,
If I were to revert to default would there be anyway to restore the OC that the pc came with? Please keep In mind that I wouldn't have a clue how to do it myself as I am not great with Bios settings etc!
If not I think I would be more comfortable trying the voltage increase first. (the people who made and Overclocked the PC are the ones telling me to increase the voltage)

Another thing i should mention Is that the computer will only give the blue screen every now and again Its not a regular thing at all maybe 2 times a week.

 

Oh ya, there's nothing written in stone here. Once you learn what to do and how, then you can start slowly on your own. Let's get it back to default and see what happens. BSOD's are not ever a welcome thing, even at twice a week. It just shouldn't happen.

 

Ok great.

In the morning I will revert It back to default and let you know how It goes!
(Its getting late here In the uk!)

Its a shame to see when you spend so much money on a pc that they cant even get it correct and then have the cheek to give you poor tech advice!

Also Im never afraid to learn so maybe this Is the best approach
(If I manage to blow my Pc up though my opinion might change haha!)

Thanks again.

 

Hi again!

So a little update to my situation

This morning I removed the overclock as suggested and found a guide online and played about for a little while and seem to have found something stable.

Guide used : http://www.clunk.org.uk/forums/overclocking/39184-p67-sandy-bridge-overclocking-guide-beginners.html

I must admit I didn't follow the guide to the letter but the cpu voltage seemed to be the problem after all.(Before I increased the CPU voltage running prime 95 would cause instant BSOD) I currently have the CPU voltage set to 1.35v running a overclock of 4.5mhz.

I have been running a stress test using prime 95 and Realtemp to monitor heat as suggested in the guide for the last 30minutes and so far so good.
the max temp i have reached under full load is 62C and from my research this is a safe level??
(I should also note that my thermaltake frio fan speeds are only set to 50% and could be increased by another 50% to reduce heat if needed)

does this seem ok to everyone? or Is 1.35volts to high for a 4.5mhz overclock?

I have never overclocked before so I could really use the confirmation

regards
Matt

 

Excellent voltages and temps. I had my Sandy at 1.38V, 4.6 and 70C. Good job!:major

 

Great!

Thanks so much for your help Augiedoggie.
I am much more confident now that I have performed the OC myself and to be honest It wasn't as complicated as I thought It would be!
Everyday is a school day :-D

So far stress testing for 1.30 hours and max temp is 64c and stable.
