梦回GTX9系，NV BIOS数字签名被破解，BIOS可以随意修改
怀疑是NV有意放出来刺激市场用的https://www.techpowerup.com/312631/nvidia-bios-signature-lock-broken-vbios-modding-and-crossflash-enabled-by-groundbreaking-new-tools 有啥用，能解锁核心电压了？ 修改显存容量成为主流 ？ 当年maxwell改bios还好玩的 那些供电和散热能力溢出的型号有福了。丐版直接刷成旗舰版 所以会有4090 48g？ 4080 32g? 3090 48g? 3080ti 24g? Narsil 发表于 2023-8-21 16:20
有啥用，能解锁核心电压了？
You can now play with NVIDIA GeForce graphics card BIOS like it's 2013! Over the last decade, NVIDIA had effectively killed video BIOS modding by introducing BIOS signature checks. With GeForce 900-series "Maxwell," the company added an on-die security processor on all its GPUs, codenamed "Falcon," which among other things, prevents the GPU from booting with unauthorized firmware. OMGVflash by Veii; and NVflashk by Kefinator (forum names), are two independently developed new tools that let you flash almost any video BIOS onto almost any NVIDIA GeForce graphics card, bypassing "unbreakable" barriers NVIDIA put in place, such as BIOS signature checks; and vendor/device checks (cross-flashing).
The tools bring back the glory days of video BIOS modding using utilities the likes of NiBiTor (now discontinued). The possibilities of such utilities are endless. You can, for example, flash the BIOS of a premium factory-overclocked graphics card onto your close-to-MSRP graphics card. In addition to clock speeds, BIOS modding now lets you raise power limits, which have a more profound impact on performance, as they increase boost frequency residency. BIOS modding also gives you control over the graphics card's voltages, cooling performance, and fan-curve, so you can make your card quieter, as long as your cooler can keep the GPU away from thermal limits (which you can adjust, too). You are now able to restore a voltage of 1.1 V on your RTX 4090 GPU, if you've got one of the newer models, which ticks at 1.07 V only.
PL可以随便改，但是电压还是不能突破核心上限 堆料的可以上了 能为20系显卡启用SAM吗？ 所以可以直接显卡里面设置功耗电压墙了 懒得折腾,也翻不出个花来 slymitec 发表于 2023-8-21 16:37
9系
意思GTX 980ti可以大艹，还是可以搞出12GB的？
是的 当时可以操到打1080的 维修显卡的 UP 收入又可以增加了 kingw12 发表于 2023-8-21 16:43

3080不用艹就可以拿捏4070[流泪] wasili8888 发表于 2023-8-21 16:39

是的，不用软件改了 可以3090改单面显存了嘛？ vasomax 发表于 2023-8-21 16:43
懒得折腾,也翻不出个花来
对GA102, AD102核心的卡意义比较大，别的无所谓 BFG9K 发表于 2023-8-21 16:47

太棒了 少一个启动项 感觉利好4080 4070ti这种，4090功耗以及傻* 16pin接口问题功耗拉高了问题太大了 没啥影响，我都是用核显的 proc 发表于 2023-8-21 16:38
能为20系显卡启用SAM吗？
官方工具就没有这个选项，我觉得难。 利好各种卡功耗墙的卡, 尤其是功耗墙比较低的10/20旧游戏本
比如移动版2060, 早期PL只有80W还碰上老黄封死硬刷, 不拉小飞机游戏里经常只有1.4G 让死水一般的DIY市场多点活力 坐等2080TI 44G了 4080显卡是不是可以狠超一把了？毕竟用的超标散热器。 是不是假卡又会出现 qjb2008 发表于 2023-8-21 16:24
所以会有4090 48g？ 4080 32g? 3090 48g? 3080ti 24g?
那专业卡真就卖不出去了。

仔细看啊 bios是随便刷 但是支持第三方修改的bios最多只能20系
所以新卡不必担心 最多是4090这种1.07v的给你刷成1.1v的
如果不造成硬件损坏的话 就算刷了那也没什么损失啊[睡觉] PolyMorph 发表于 2023-8-21 16:46
3080不用艹就可以拿捏4070
功耗上也能拿捏，用接近2倍的功耗获取相同的性能。如果不是黄狗作妖，现在的4070根本就不配叫4070。
