Thread Starter 
With regards to ivy, what is the highest safest BCLK 24/7 above 100Mhz?

I wouldn't be too worried about a high BCLK. Voltage is what you should worry about for 24/7 usage. Why are you adjusting the BCLK though? When overclocking, you should be adjusting the multiplier generally.

I realized that with 102.2Mhz you could go with a multiplier of x47 to get 4.8Ghz, I just ordered a Phanteks PH-TC14PE so I can't run it till I get the cooler. Or 102.2Mhz and x48 to get 4.9Ghz.

What voltage are you recommending not to exceed in offset?

I would recommend just leaving the BCLK at 100 and upping the multiplier to 48 or 49 depending on what you want. Once you start messing with the BCLK, you start effecting other system settings as well like the ram speed which can lead to instability. Voltage depends on the generation, but for Ivy, I would recommend staying under 1.4v for 24/7 operation.

i like to sit just under what people think is a safe voltage.

i personally believe in achieving the highest cpu speed within the intel voltage spec, which i am not sure for ivy, id sit under 1.35. but in saying that alot of people use 1.4 to achieve awesome clocks or unless there is ample cooling and you think alot more is worth it e.g 300mhz then go for it.

its all determined by your heat production and stability. for all you know your cpu could be a boss and handle 1.45 volts daily for 15+years.

i even think cpu heat doesnt really degrade life they are rated to 105,c sitting at anything above 80~85c thats when long term electron migration may start but even then 105c...... if you go stupid on heat and voltages (over 85c daily) you can then do damage called electron migration. but in saying that overvolting safely to 1.35v could also change the sensitivity of the cpu and electron migration may start slowly after 2 years or whatever. Thats why i wanna sit within the intel spec so long term usage and overclocking can somehow be prevented from growing this cancer slowly in the chip. i learnt the hard way with 2 Nehalem 920/930 i7's

Good luck, if your REALLY worried buy a second board and chip and keep them in the cupboard so when you fry your guy you can swap **** out asap.


Dizzy is also right about the rest. if u can just screw in the strap and whatch your clocks fly. hell put it on auto screw in 5ghz and down the voltages that where set by auto.

I agree, I've just come from the 3770k degradation thread and realized no one seemed to have their chips degrade at 5Ghz , 1.488v and great temps (80 and below). I won't be needing a second board/chip so am going to play it safe but aggressive, am really not interested in 5Ghz coz it comes with a hefty price. Probably something very close

As far as the ram is concerned one can change the ram multiplier to prevent the ram from being overclocked. So guys are you telling me that 102.2Mhz isn't safe at all for ivy overclocking??

Pretty safe, I've stability tested at 110 bclk with a 3770k, if an SSD or HDD hates extra pci-e frequency failing to detect the drive or data corruption could be a possibility, although the worst drive I've seen started having issues at 109 pci-e.
I've heard damage from higher pci-e is possible, never heard of anyone actually damaging anything though.
