可调整基址寄存器 (Resizable BAR) 是一个可以在主板 BIOS 中启用的功能,它可以使显卡直接访问主存,从而提升 GPU 的性能。你遇到的问题可能是你的电脑主板并不支持 Resizable BAR 功能,或者在启用时出现了问题。这需要根据你的具体情况进行排查和解决问题。以下是一些可能的解决方法:1. 检查你的硬件是否满足要求。有...
自从AMD推出了Smart Access Memory（SAM）功能后，英伟达很快便借助PCI Express技术标准，提供了相似作用的Resizable BAR，现在许多主板的BIOS都能开启这项功能。作为近几年的一项新的性能优化功能，可以让CPU直接访问显存，消除了瓶颈，从而提升大概10%的游戏帧数，不过这玩家需要使用基于Ampere架构的GeForce RTX 30系列显...
I'm considering using an External GPU on my laptop that requires Re-Bar to work properly. Below is the report GPU-Z generates. It's saying the current (internal) GPU is unsupported, which is fine, but what I want to know, is if I buy and attach an external GPU, do I have all...
Although [Resizable BAR] and [Above 4G Decoding] are actually enabled in the BIOS,Intel Arc Control prompts [Resizable BAR general-not-supported] and [Automatic system support detection is not available] I have written to ask the motherboard manufacturer and followed the steps given ...
Since GPU-Z shows Resizable Bar as Enabled and Intel® Arc™ Control shows Resizable Bar as unsupported. It appears to be aesthetic in nature since Resizable BAR is enabled. We are aware of the situation and Intel is investigating this issue. We are working really hard to solve...
notice that in GPU-Z, it will show UNSUPPORTED GPU under GRAPHICS DRIVER SUPPORT and RESIZABLE BAR ENABLED IN BIOS. You can stop here since there is nothing else that can be done. You will need to physically update your GPU hardware to a model which can support the Resizable Bar feature....
Currently there is no known method to get it on Windows without BIOS modification I set an unsupported BAR size and my system won't boot Clear CMOS and Resizable BAR should be disabled. In some cases it may be necessary to remove the CMOS battery for Resizable BAR to disable. Will less ...
