Battery Backup required for Overclocking?

post #1 of 7
Thread Starter 
Hi all. I'm new to oc'ing a cpu and am having problems with my vcore not being constant. I'm using the rig in my sig. I talked with my cousin and he said that I may want to try hooking my computer up to a battery backup so that my incoming voltage is constant.

Could the lack of using a battery backup cause my vcore to fluctuate between 1.238 and 1.384? Are UPS's required for overclocking and stability?

you do not need a battery backup. the power supply takes care of all of that. although, you should get one eventually. they are very nice to have...i can run my computer, 32" LCD, sound system, and cable box from the battery for almost an hour....rediculous

Frack! What size UPS are you using?

Mine is 810W and between one 24'' monitor (I only keep backup power to one monitor so I can still shut stuff down), my sig rig and my home server that draws 73W on idle (and it mostly only idles) I get ~10-14 mins. If I were gaming and the power went I'd have about 5.

I would think that kind of fluctuation on the Vcore would be related to a board/PSU than clean/dirty power. The PSU should normalize power to the components, the UPS normalizes power to the PSU itself.

Your voltages fluctuate due to Vdroop. It is an Intel specification where by the voltage drops while under load to prevent voltage spikes. If everything is on the default bios settings, your voltage will also lower while the CPU is idle to save power. It is not in any way related to having a UPS.

Okay...so it looks like my vdroop may need to be adjusted then? The question is how much??? I'm really starting to think I got in over my head with this whole overclocking thing...even if the 2600k is supposedly "easy" to OC... "easy" is definitely a subjective term!

Just to dispel any confusion: a UPS -- or battery backup -- does exactly nothing for your PSU's voltage regulation.
A PSU with active PFC accepts a wide range of AC voltages, and it doesn't terribly care what it is so long as it's within acceptable limits. It just adjusts to whatever is fed to it. The internal components take care of converting that AC power into several different, tightly regulated DC currents (chiefly +3.3V, +5V and +12V). But whether you're hooked up to a UPS or not won't make a difference.

Thanks for the info. Well hopefully this is just a vdroop or some other mobo setting. I'm a little concerned it is my psu because being the noob I am at building a cpu, I plugged the chassis fan on my case into both the fan header and the PSU. I know I had booting issues with the mobo after this..but I don't know if it affected my PSU....
