Overclocking BCLK 2600K

post #1 of 9
Thread Starter 
What voltage do i raise to get a higher BCLK?
post #2 of 9
you should only raise multi on the 2600k. raising bclk will cause stabilty issues. you probably might be able to get a slight increase with bclk.

Raising anything above stock can cause instability. After doing a bit of BCLK testing, I'd say keep it below 105-106MHz since beyond that seemed to produce too many issues for minimal performance gains.

I currently run 104.6MHz with a 46x Multiplier.

Do not mess with BLCK, only multiplier.

I can't confirm it, but alot of people are saying that anything above 100 can reduce the life of your chip/mobo.

Raise VCORE, and CPU-PLL to get higher clocks with the MULTIPLIER.
post #5 of 9
I just did a test, to find out if it makes sence to raise the BCLK compared to raise the multiplier.

You can see my results here:
http://sites.google.com/site/qwwwizx/Overclocking/bclk-106

I dont see any stability issues, and my memory is the cheepest corsair 4x2GB modules 1600MHz available. I got them in january with the rest of the system for less than $100 USD. If you manually set your memory voltage I think you are fine.

I use my computer everyday, for games, work and benchmark and it has been running 5Ghz+ from January.

Just did the same test again on my asus gene-z and got the same results. BLCK isnt doing anything that have negative or positive impact on performance.

For some reason the gene-z board have issues when booting with bclk at 106Mhz, but after a few tries it comes up.

Decrease cpu pll to 1.65v. Increasing it will make things worse.

Nobody can confirm that. Its hear-say. These chips arent old enough for anyone to have experienced decreased life span due to tweaking the bclk. Common sense people, common sense.

You can play with the bclk. Anything above 108 is pretty rare though. And I would not recommend anything over 103-104 for 24/7 use.

I will try to see if I can do it above 108. Havent tried above 106 which I felt would be enough to conclude performance increase or not.

My chip can handle a lot. Used it for OC since january, daily vcore at 1.45v-1.5v, benching 1.6-1.8v, and even had a defect pump accident. Used it every single day and still no difference in capabilities. The memory though, gets clocked up with bclk and I have burnt a couple of memory modules before - learnt my lesson there so I am carefull in that area.
