Yes, you can add another 2x8GB DDR3 RAM kit.
Consider adding another 2x8GB RAM module for your upcoming modding projects. Your current setup with the Asrock Z97 Extreme9 and i7-4790K supports up to 32GB, so it’s feasible. The G.SKILL RipjawsX you have is compatible, though a newer 2018 kit might offer better performance. You could also explore a dedicated 4x8GB configuration if you prefer maximum capacity.
take a look at the burner screenshot to spot the issue. The model matters more than the revision, but the maker counts as crucial since most low-quality Samsung 4G models settle around 2400 while Hyundai 4G models run above 3000. I strongly warn against buying XMP DDR3 4GB (SR) and 8GB (DR) modules—those lower ranges often come with faulty Samsung chips that can be easily damaged by Hyundai parts, even in OEM form. They’ll still cost more than standard OEM units that match the same specifications. The PCB on XMP sticks really matters; you’d notice differences if you checked old photos. I didn’t capture the actual boards, but they’re HMT351U6C 1600C11 blue PCBs based on Hyundai 2Gbit CFR. I managed to get DDR3 2800C11 stability with an i7, but only in dual-channel mode because triple-channel needs extra cores. Any ratio from 1:1 to 2:1 is unstable at 45nm. Remember, 4GHz Hyundai clocks are higher than 2GHz Samsung, so OEM 8GB sticks (like HMT41U6MFR/AFR/BFR8C) will hit DDR3 3000+ if the IC is solid enough—X58 still has worse performance than Haswell. My best chip (W3680) only nailed DDR3 3008C11 dual-channel for about two hours before failing, likely due to channel issues. The outer channels usually work better; the innermost one with poor IMC often causes problems. For a 2600+ clock speed, expect board limitations and probably need tuning. Aim for a range of 2400–2800, but be cautious with 2600+ because of compatibility limits. If you’re unsure, stick to 2400 and double-check the specs.
