  1. Hey everyone, Just finished building my watercooled rig last week and I found some interesting results that raised a few questions for me... First off, my parts and my loop: Crosshair V formula (Non-Z) AMD 8350, 4.7GHz @ 1.48125V R9 290X, 1115 Core and 1450 Mem @ +50mv CoolerMaster Silent Pro Gold 1200W 240GB & 256GB SSD 2x 500GB HDD EK 140mm Res > D5 @ Setting 5 > 360MM EK PE Series Rad > EK Supremacy > 120MM EK PE Series Rad > EK 290X Block w/Backplate > Res I've been testing for the past couple days using games and benches (Heaven, Valley and 3DMark) while using MSI AB to monitor Core/Mem fluctuations. After thorough testing, I've found that the core will throttle after 50mv. Temps are NEVER A PROBLEM (45c Core, 50c VRM1 and 42c VRM2) so I have no idea why it would throttle. I double checked the seating on my card, made sure that the VRM's had contact with the thermal pads to the block... basically the install was perfect. I tested by using the same clocks above, power limit maxed at +50 and running extra voltage at 50mv and 56mv. While playing games and running benches, the core didn't stay rock solid @ 1115Mhz on +56mv. I dipped as low as 25MHz sometimes. I know its a rather small number but its just weird that adding +6 mv would cause it to throttle. Maybe I got unlucky with the silicon lottery or maybe I'm missing something? Thoughts?
