For those users who thought they'd like some silver with their Intel, german webshop Caseking has a product for you. The company has taken the binning concept that we've already seen with other webshops, which pass the onus of the silicon lottery towards themselves, and taken it to the next level. Caseking will offer Core i7 8700K products that have not only been binned towards achieving guaranteed speeds of 5 GHz, 5.1 GHz and 5.2 GHz, but they're also retrofitting these binned 8700K processors with a 99.9% purity silver heatspreader to improve operating temperatures for these guaranteed-overclocking processors.
Caseking is basically testing batches of i7 8700K processors, delidding them, and then applying Thermal Grizzly's Conductonaut liquid metal thermal grease and the aforementioned silver heatspreader to improve operating temperatures as much as they can be. The company is doing this in partnership with overclocking poster child der8auer, and brands the silver IHS with both Caseking's and Der8auer's logo. The silver heatspreader versions of the Core i7 8700K are being sold as the Ultra Edition, and Caseking are asking a hefty premium for their binned CPUs: €690 will get you an 8700K that is guaranteed to clock up to 5.0 GHz, €750 will guarantee 5.1 GHz, and the premium of premiums (for now, we'd imagine) 5.2 GHz overclockable processor will cost €870.
These are some hefty, hefty price premiums to be sure; however, the company really is taking many risks out of their prospective buyer's hands, in that they not only won't have to bet on the silicon lottery to get some good results, but also won't have to run the risk of delidding their six-core Intel CPU. There's also an Advanced Edition (stock heatspreader with Thermal Grizzly Conductonaut) and a Pro Edition (Niquel-plated heatspreader with Thermal Grizzly Conductonaut) available, for lower prices than the silver options.
