Roman is a true hardware geek, this is so awesome:
Here is an interesting article with help from Overclockers UK, a daughter firm of Case King (where I bought my current pc build 's parts):
De-lidding Speed-binning Explained - Introduction
De-lidding CPUs has recently become much more popular in recent years, with many enthusiasts seeking the lowest possible temperatures, and in turn, the highest achievable overclock from their piece of silicon.
Overclockers UK, based in Newcastle-Under-Lyme, invited us down to investigate their de-lidding and speed-binning process. We spent a day working alongside Ian 8-Pack Parry, world-renowned overclocking guru, and the OcUK Tech Labs Team to witness the procedure first hand.
You might be left wondering “what on Earth is de-lidding and speed-binning?” The process of de-lidding a CPU is removing the Integrated Heat Spreader (IHS), cleaning off the factory-applied thermal paste and replacing it with a more efficient liquid metal, aiding heat transfer from the CPU die to the heatsink above, with the aim of decreasing temperatures.
Speed-binning involves running a CPU through a series of stringent tests, designed to identify any weakness within the CPU; think of this as a military selection exercise, where only the best will be selected. This process is necessary due to the unique properties of each CPU; where tiny imperfections within the silicon can affect their ability to overclock above their rated boost speeds. This is referred to as the “Silicon Lottery”, which 8Pack kindly removes for you.
De-lidding is an inherently risky procedure, with a chance of completely ruining your CPU. Does the temperature difference warrant such a risk? Or is it best to leave this to the professionals at OcUK?
Hi,
I read this a lot and is vccio and this is in the bios but also "vccsa which is not a bios listing are people really referring to cpu system agent" or what :)
If yes why not say cpusa
Mike, I think some boards list things different. VCCSA is the System Agent voltage and VCCIO is voltage to the memory controller, I'm pretty sure. Mine lists it different. CPU VCCIO voltage and CPU System Agent Voltage.
