In addition to the GTX 550 Ti DirectCU and TOP Edition working at 975MHz, Asus has also announced the GTX 550 Ti Ultimate Edition clocked at 1015MHz for the GPU.
It looks like Asus decided that GTX 550 Ti is quite stable over the 1GHz mark, and even memory got overclocked to 4200MHz. The TOP Edition works at 975MHz while the DirectCU one ended up overclocked to 910MHz. Both version swill have memory clocked at 4104MHz. It looks like GTX 550Ti is quite an overclocker, and it will be interesting to see how far can it actually go.
Most partners are sticking to 1000MHz for their overclocked editions, and it was simply a matter of time before someone actually got over it. All three cards use GF116 GPU with 192 CUDA cores and pack 1GB of GDDR5 memory paired up with a 192-bit memory interface.
According to Asus, the new GTX 550 Ti Ultimate should be available as of next month with a price tag set at €168.
