    Update BIOS to latest, set VCCSA to 1.1v, disable memory fast boot, choose Gear 1, set memory reference frequency to 100:133, then try changing the dram frequency to what you want

    12th gen ddr4 controller is rated for 3200mhz by Intel but unlocked chips can do higher unless you got really unlucky

    I have a 12600kf, I’m using 1.25v system agent, 1.3v vddq, 1.45v dram to get 4000mhz working in Gear 1. I have single rank Micron rev B so it’s not too taxing on the memory controller. Dual rank would be more difficult




  • RockyXvII@alien.topBtoIntelWhen do you usually upgrade your processor?

    When FPS isn’t enough or it’s bottlenecking my GPU too much. I went from Ryzen 2600 to a 12600KF at its launch in Nov 2021 because the R5 2600 was holding back my 6800 XT way too much in practically every game. When I got the 12600KF the bottleneck was significantly decreased and performance was up. I play at 1440p and notice still a little bit of bottleneck in some games, GPU usage won’t always be 99%. But after I overclocked the CPU and RAM… It’s chef’s kiss immaculate

    Need to upgrade GPU now if I want more performance, especially after seeing games like Alan Wake 2 and Cyberpunk RT being a little problematic with this card. Waiting for 40 Super cards and Arrow Lake




  • Nice results especially on that 6700 XT!

    My 6800 XT Gaming X Trio has a 30-35c delta. In games like Alan Wake 2 and Cyberpunk the avg core temp reported bounces between 70-72c but the hotspot will be 100-105c. This is with a reported power draw in Adrenalin of 280w. Had the card for around 2.5 years now and never repasted. The temps have always been high. Seriously considering a swap to PTM7950 to bring that delta down so the gpu fans don’t keep ramping up to 2200rpm and maybe I could increase power limit to overclock a bit further

    Thanks for making this post



  • There are no dedicated AI cores in RDNA3 (RX 7000)

    AMD specifically call them “AI accelerators”. They schedule the matrix computations to be calculated by the texture units on the card using WMMA instructions

    This is the same technique they use for ray tracing. They don’t have dedicated cores. The ray bounces are traced by texture units. That’s why AMD is behind Nvidia in RT

    It saves them money on die size
