Highest voltage?

post #1 of 9
Thread Starter 
I want to OC my CPU to about 4.4-4.6GHz. Will that be stable or should I shoot for something more like 4.2? I AM running on water. Temps right now are low to mid 20s idle.

I just want to know how much voltage I should apply to this change. I don't want to do anything unnecessary. Anyone know?

It depends, no overclocks are the exactly the same. i7's do run at a lower vcore than most other processors. What's the voltage at right now?

Edit: I'd say probably around 1.35 volts should get you to that number. But like I said, it depends. Everyone is different. You might be able to hit that number using a lower voltage.

I'd be more than comfortable running 1.45v max on my chip underwater.

I'm getting my watercooling in this week, can't wait!

Depends on how much you push your ram and cpu, since the memory controller is built into the cpu. Mine did not require extra qpi voltage to stablize, however my cpu running at 4.52ghz ( keep in mind it is a six core ) runs stable @ 1.51v and it stays cool. on a quad core you shouldn't need to push it past 1.45v, that's a good range, but keep in mind the more voltage you dump in the processor past stock can decrease its life expectancy. Voltage = Heat, Heat = Degredation. Avoid going past 1.55v as anything int the 1.6-1.8 will either degrade it fast or kill the cpu. I personally capped my setup @ 1.51v, and if I do see any stability issues (none so far) I will reduce the voltage/clock speed as I don't want to replace the 970.

this is not true. voltage will degrade a chip much faster than heat. you can run a CPU at 100% load all day and it will get plenty hot, but it will be fine. you put the wrong voltage through a CPU once and you will fry it. chips can be fairly robust, within limits.

make sure you stay within the Specs of your CPU. what are you running that you need 4.6ghz out of a 980x that 4.2ghz wont run?

Just because you stay under the range that will fry a cpu doesn't mean the added heat won't degrade your cpu. Heat is the enemy of ALL Computer components, and this is true.

this has been debated many times on these forums, voltage kills chips. heat kills them too, but over long periods of time. the voltage will be more dangerous, immediately

hi i got a 2600k clocked to 5.0 ghz @1.385v is this ok as 24/7 clock, what would be a safe 24/7 voltage for this cpu i dont do folding just Bad Company 2 24/7 cpu loads are around 70%
got water cooling on it
