Guild Wars 2

Turned off the memory X.M.P. profile in bios and AUTO DRAM frequency ON,
24h no crashes.
(X.M.P on before and DRAM locked at 1600MHz).

Continued: running GW2 in windowed mode (1h) and it crashes, have a MSI GTX 570 OC so i tried using MSI Afterburner clocked down the GPU, the game run for an 1 hour then crash! Other games run just fine! Will try Memtest on my 16 Gb of RAM now

Same issue here, Win 7 64bit, GTX 570, i7 2600k. 30 sek to 1h playing then crasch. Moved game from SSD to HDD still crasching, 3 different GPU drivers and crasch. Feels like a bad Betas test!
