Introducing the Radeon R9 Fury X the HBM memory overclocking was locked for security reasons, but some experimenters have managed to raise the frequency of this memory type . Anyway, they thought so - utility GPU-Z showed a change in memory frequency . However, colleagues argues that the possibility of increasing the HBM memory frequency is locked, and even if the utility GPU-Z lets you think otherwise, it is not.
But colleagues report about the possibility of changing voltage, which some enthusiasts even managed to open on the reference Radeon R9 Fury X.
Most interestingly, a new publication on the site WCCFTech already talked about successful experiments on memory overclocking and voltage variations on video cards Radeon R9 Fury X. To do this, just need to use the utility MSI Afterburner, which allows you to raise the frequency of the GPU is not only Fiji, but the HBM memory . Associate tested Radeon R9 Fury X overclocking the memory up to 540 MHz at a constant frequency of the graphics processor, and the results suggest that the performance of the graphics card at the same time increased. Thus, overclocking memory on Radeon R9 Fury X is blocked only in official drivers, and third-party utilities allow you to access it.
Regarding the possibility of increasing the voltage, it will be implemented in new versions of utilities such as Sapphire Trixx and MSI Afterburner.
