Intel blocks overclocking on H81, B85 and H87-chipsets

Recommended Posts

Posted · Original PosterOP

Intel will block overclocking on all their 8-series chipsets exept the z87 that is meant to use for overclocking.

Intel is producing at the moment new cpu's where the bug is fixed that allowed overclocking, the microcodes in the cpu's are re-written and for using the new cpu's a bios-update will be needed.

 Intel is even planning to push an update through your OS that automaticly updates the BIOS so you are "forced" to stop overclocking your CPU. (unless you have a Z87 board of course).

The launch of the updated cpu's will be arround week 30 of 2013 but when the updated cpu's will reach the market is unknown and when the boards will have a new bios is also unknown.

Sorry if this sounds dumb, but what's the difference between H81, B85, and H87? I knew that the non z chipsets were never meant for overclocking, but is there any difference?

Does anyone who buys into a non Z chipset even plan on overclocking anyway? And do any non Z boards have good enough hardware on them for over clocking? It doesn't seem like a huge deal to me, all you can do on non Z boards is bump up the FSB, IIRC.

Their non-z chipsets are since the 1155 socket not meant to use for overclocking, but because there was a bug in the cpu's the motherboard manufacturers were able to allow overclocking on non-z chipsets with socket 1150, it allowed to boost up the voltage and the frequency a lot and you were able to receive the exact same overclocking results als on a z87-chipset board, If you are on a small budget and want to experiment a bit with overclocking it was possible, like AMD allows with their cpu's. The overclocking possibility was indeed not official, but possible.

Hello! Yes there are other differences! Look at the chart posted on the above page^^^

H81 is usually the cheapest because of the reduced features and Z87 is the most expensive. 

B85 is more of a budget business oriented chipset.

H87 is Z87 without overclocking and a max of 2 way SLI/Xfire comared to 3 way of the Z87 chipset.

H87 also does not include Intel Lake Tiny technology which improves SSD caching and reduces SSD power consumption.

 

Let me know if you have any more questions!
