So i need to overclock my proccessor to 3.8ghz so that it won't bottleneck my new r9 280x
My rig is:-
Cooler master elite 431 plus with 2 fans on top 1 rear and 1 front fan
Hyper 212 evo
6gb of low profile ram
890gxm-g65(msi)
R9 280x twin frozer

My cpu temp at idle is 17* C and during gaming is 20* C
Recorded with HW monitor, msi afterburner
The voltage is at default,haven't messed with overclocking yet.

I'm looking to OC it to 3.8ghz so what multiplier and voltage do you reckon I should put and what stress testing program should I use to test my cpu.

the multiplier is an easy one, do the math, take whatever the FSB is and divide 3800 by the FSB. The voltage is going to take some trial and error. Just start bumping it in small increments and see what will allow it to boot.

there are two schools of thought however, some just want to go straight for 3.8, another option (way I would go) is slowly work up to it, maybe start at 3.2 or 3.4 and work up .1 at a time so you can see if you suddenly hit a voltage wall.

I've got a question,lets say my voltage is 1.3v and its at 18 multiplier,next round I set it to 19 multiplier and same voltage,it doesn't boots to desktop.Can I still access my bios or what can I do to return to the last stable OC

Not sure on your board, most will fail to boot between 3 & 5 times then throw you back into bios. if it fails to boot more than 6 or 7 I would power down the board and reset the cmos (either with the jumper, or unplug. pull battery, wait 60 seconds, push power button, put battery back in, plug in, try again). once you do get in bios most have a "previous settings" option. I would save 2 or 3 working profiles in different names on the bios as you work your way up just to ensure that it loads working values. When I try something like this I unplug everything unneeded, just memory, HD and a processor, not sure the boot loops can hurt things but they can't help any parts :p

unplug power ac from psu, find jumper cmos reset in motherboard (read guide your book for reset bios ) I'm not going to dig through your entire manual to look up how to reset your bios. If you aren't comfortable removing a stick or two of memory, and a GPU, I'm not sure you need to be trying to OC this thing. That is just my personal opinion however.

There is a CMOS RAM onboard that has a power supply from an external battery to
keep the data of system configuration. With the CMOS RAM, the system can automatically
boot OS every time it is turned on. If you want to clear the system configuration,
set the jumper to clear data.
JBAT1 Keep Data Clear Data
1 1 1
Important
You can clear CMOS by shorting 2-3 pin while the system is off. Then return to 1-2
pin position. Avoid clearing the CMOS while the system is on; it will damage the mainboard.


the CMOS to clear the bios is labeled JBAT on the board, move the jumper to the right to clear it (ONLY DO THIS WITH SYSTEM UNPLUGGED) will put the bios back to default.
