My Build Overclock

[ovechkin1313]

Hi! I recently made a computer build worth 1249$ for the ultimate fsx experience!

My specifications are : Intel i5 2500k quad core processor @ 3.3ghz

ASUS P8Z77-V ATX LGA1155 Z77 DDR3 SLI 3PCI-E16 2PCI-E1 2PCI SATA3 DisplayPort
Antec HCG-620M 620W ATX12V Modular SINGLE-RAIL 48A 80PLUS Bronze 135mm Fan
EVGA Geforce Gtx 560ti
16gb ram -- kingston ddr3 1600 8gb ram ( 4x2) x 2
Antec 300 case
Coolmaster 212 evo
23" led monitor
So my question is, i want to overclock my processor to 4ghz , but i want to use STOCK VOLTAGE , i couldnt find a guide on it , so can someone tell me what to change? I know my base clock stays at 100mhz plus 40 multiplier equals 4000mhz = 4.0ghz. But do i keep my voltage on auto when i do this? Or do i put it as manuel and put in stock voltage I want stock voltages , because i want this computer to last me 5 years. Also can someone tell me what the stock voltage even is for the i5 2500k? And what settings do i change for it. The last thing i am also worried about is BSOD, if that happens, how do i reset my system, AND is 4ghz OC ON STOCK VOLTAGE acheivable? Thanks in Advance I didnt get an answer last time , soo please this time give me one!!!

I'm not sure if it's doable on stock voltages but you can try it.
Change the voltage to manual. It should be on the stock voltage so that's what you want it on. To overclock you can change the multiplier or the base clock. You only need to change the voltage when the overclock becomes unstable

I OCd my 2500k to 4.53 and my voltages are still on auto. Haven't had any stability issues.

If OP wants to use stock voltage then it should be set to manual right? Because in auto the voltage would automatically be increased to cope with the overclock....I think. Could be wrong

yeah thats the same issue im having , i think they do change, and the bios puts in more voltage then needed; but can i just open my bios and literally just change the multiplier to 40 and the base clock to 100mhz? with manuel stock voltagE?

 

[akxpckwb]

Yes you can. However it is best to change the multiplier to 40 and slowly increase the base clock. That way even if you don't get to 4Ghz at least you'll know how high you can go on stock voltage

ok! : ) before i give u top answerer , can u tell me what the stock voltage is for i5 2500k , that i can use without causing any damage?

I'm not exactly sure but it should be something around 1.2 or 1.3. You could just leave at auto too. Unless you somehow screw up big time the auto feature will not fry your CPU

So! Basically , i go into the bios and ONLY change the base clock and multiplier and put voltage manuel and stock ; NOTHING ELSE right ? thanks!! ) sorry for teh stupid questions , first computer this expensive , and cant afford to loose it LOL ( im 15 )

Core Voltage - Not recommended to exceed 1.38v, doing so could kill the CPU, recommended range of 1.325-1.350v for overclocking.
Memory Voltage - Intel recommends 1.50v plus/minus 5% which means up to 1.58v is the safe recommended limit. In my testing I've found 1.70v has caused no issues, depends on the RAM you buy.
BCLK Base Clock - This is strictly a NO, anyone using base clock overclocking could/will cause damange to CPU/Mainboard (Set manually to 100).
PLL Voltage - Do not exceed 1.9v!!

Can you overclock 4GHz and higher on stock voltage? Of course, but it highly depends on three things: Mainly your specific sample of CPU (which determines how high and with how low of voltage you can overclock), the quality of mainboard you use, and just important; the quality of power that your power supply delivers. I really recommend having a SeaSonic power supply like the X750 Gold if you're going to attempt low voltage overclocking ( http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087 ).

Keep in mind what s3anister said while overclocking.
You seem to not be an experienced overclocked I would even say it's probably your first time. In that case I seriously recommend that you read the basic overclocking guide for your CPU http://www.tomshardware.co.uk/forum/265056-11-2600k-2500k-overclocking-guide

thanks for message! , im going to try 1.1v - 1.19v for a 4ghz overclock , or 1.21 fora 4ghz overclock , is this completly safe? my blk clock speed will be 100mhz multiplied by a multiplier by 40. Thats it , no other changes at all .

Going above 1.52v is when you can kill the cpu.
