My Turbo Multiplier is already at maximum (42 x 100)
Now, I'm increasing my BCLK bit by bit.
So far, so good.
I have a Zalman cooler and 2 x cooler master blade master
So, my temperatures are still good at maximum stress.
My question is: ones I have found the maximum stable BCLK
and my stress test is still good after 24 hours, is it safe then
to keep these overclocking settings forever ?
Or are there still risks that my motherboard will be damaged soon ?
(it's lifetime is still decreasing with other words)
Not worth OC'ing a non K by uping the bclk. a 10 % increase in normally not detectable in normal operation and by increasing bclk you are also increasing the freq to other components such as the pci-e which should be kept close to 100 mhz.
BCLK OC'ing was the thing with the Intel 9xx series CPU's but w/ SB the multiplier is selectable and most OC'ing is done there. You can squeeze the BCLK t 103 or even 105 if ya wanna push it, but most consider it more trouble than its worth.
I'd get the CPU max to around 4.6 - 4.8 (whatever you can maintain good temps with). What I normally do w/ the 2600k's is set up two separate BIOS profiles.
24/7/365 OC - Set CPU to max multiplier of 44 - 46 (again, what temps will allow) with HT on.
Extreme Gaming OC - Set CPU to max multiplier of 48 - 50 (again, what temps will allow) with HT off.
With a good cooler, your temps should be OK, low max multi's will be needed with lower performing coolers ..... not all CPU's will do 4.8 tho
1. Approximately 50% of CPUs can go up to 4.4~4.5 GHz
2. Approximately 40% of CPUs can go up to 4.6~4.7 GHz
3. Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)
The non K version of i5 2500 can be overclocked to a maximum of 4.3Ghz(1 core active) and 4GHz(all 4 core active) on an ASUS p8p67.Set the multiplier to 41 , BCLK frequency to 105.4 and increase the CPU vCore by 0.025V.Thats it. Ran prime95 stress test for about 30 minutes and everything was perfectly stable.
Note:I was successful in pushing the BCLK to 106Mhz and didn't try anything afterwards as the motherboard temp would reach 40C.For stability I pushed back to 105.4.
