Colorful introduced the iGame550-1024 D5 Ymir, a non-reference GeForce GTX 550 Ti with an overclocking BIOS that ups the core frequency to 1000MHz and memory clockspeed to 4400MHz. The card is now available in Asia and will soon arrive in Europe.
The card uses Colorful's non-reference design PCB that uses a 4+1 phase VRM, high-grade components, and dual BIOS that is selectable with a switch on the rear panel. One of the two BIOS ROMs packs failsafe clock speeds of 900/1000 MHz (core/memory), while the other "Turbo" BIOS runs the card at 1000/1100 MHz. The card is cooled by Colorful's iconic "Shark fin" cooler that packs large heatsinks, and some clever air-channeling mojo. The NVIDIA GeForce GTX 550 Ti packs 192 CUDA cores, and connects to 1 GB of memory over a 192-bit wide memory interface.
