D9GKX are going to die easy with 2,6 my Ballistix @ 1250 i fead them with 2,45 V
i had feed on kit Mashkin Xp2 6400 with 3Volt for Cl 3 and 10 min later the kit died

D9GMH are "listening" better than D9GKX on Volt but same think here not more than 2,3 for 24/7

now i have 1100Mhz Cl4 3-3-3 2T with 2,275Volt with more than one month Uptime
