u lucky dog! L312B515 is my favourite batch, i never had one but NameGT and JJJC reached monster clocks on these. So if you find a lucky one you in the zone.
Andreat that batch will fly if you find the right low V chip. i had 2x 6.5 and XA had 3x 6.5 on 310B491. So that batch should be fine. I also had alot of L310B488, they scaled with LN2 but i never found a low V chip before they went out of stock.
@alex, i dont have mem that can go high so i dont test IMC :<
PS: How much do you guys pay for 4770K? i pay 390$ At the distributer because i resell. I was in the mall the other day and saw 4770k go for 490$ new in stores
