What about warranty? Do they sill have any? Did you overclock your cards? For how long were they used? Did any have them got their fans replaced during that? There isn't a chance to buy a single card, is there?
Hello
Cards are around 12-13month old. They come with 2 years warranty, invoice will be given to the buyer. All cards have been OCed a bit, but not too much to prevent killing them quickier. To give you an example, if the max OC gave me 24MH/s on Ethhash for a 1060 I tried to lower a bit to preserve component, reduce electricity drawn and reduce heat.
Cards runs @ 40-50°C with an ambiant temp of 24°C in a ventilated place.
All cards are often cleaned to avoid fan problems (we choose EVGA, AORUS and MSI gaming X as they have ball beering fans (=longevity)) --> On 264 cards, NONE had a fan problem.
Sorry but we do not sell 1 card only, at least 1 rig --> We priced our rigs with the price of X cards, so if you buy a 8GPU rig of 1080ti, you will pay 8*500 (price per card) and we offer the whole rig ! Motherboard, CPU, power supply, RAM, Riser etc FOR FREE.
