T61园了4核梦

yzfh000

我尝试了超频，很可惜没能成功，用稳压电源看电流跳变似乎是挡在了内存，我只刷了一条533内存，有空我再刷两条试试。

不对，我错了，还没到内存，虽然电流有跳变，但感觉复位还没完成，猜测是某个设备或某些个设备承受不住。
兄弟你的超频方法应该是正确的，另外我觉得不割线，直接把R1024一端加1.05电压，北桥端接地也可以，和超266一样。

好吧，围观一下  LZV5

我看了下，貌似14寸的宽屏T61不管是集显还是独显，管脚D22都没有在PCB上打孔，要飞线只能从CPU插座上部引线，这不好操作啊。而方屏的主板貌似打过孔了，可以直接飞线

我看了，14宽屏的是没有过孔，不过我觉得可以用漆包线从CPU座孔引出来。

觉得最大的可能是T61的供电就不行，原本TDP 45w的供电，现在几乎要上90W。

再一个办法是找个135W的适配器。

highsun

Q9000的，温度怎么样？待机似乎不到40？ 满载呢 超过90了么？

highsun

开始你说的加套，用的是什么？热缩管么？

真牛B.顶起。

135W的我有一个，有点问题，可以送给楼主研究
还有一个是好的，是19.5V-6.25A   这个肯定比90W的要大。我用在T60的机器上

2009年胶水入门四核，win7约6.9/7.0的样子，但毕竟是4核，可以应付大部分应用了，软解4K不行，当然也没那必要啦

bryan5656

您什么时候考试完成？很期待

bryan5656

楼主这种电工活估计大家干不了……而且新平台的整体优势还是高多了

武之伯言

进来学习，牛啊！！

yzfh000

我觉得不是适配器的问题，我用30V5A可调稳压电源，应该有150W的功率吧。
Q9000待机45度，满载测试10分钟稳定在82度左右，室温20度。我还没认真处理散热，用的是几块钱一小罐的硅脂
开始用的细电线上的皮管，差那么一点塞不进去，如果能有很细的热缩管最好了，我没找到，最后干脆直接断针。

楼主 高啊 能不能帮改啊 让我的老机也升级下

I flashed the W500 BIOS 6F on a T500 motherboard (they have the same BIOS) and it did not brick but quadcores do still not work as they should. It is a step in the right direction anyway.

With the original lenovo BIOS (+ pin insulation and GTLREF2 connection) quadcores were recognized in the BIOS, but it was not able to finish boot process to a bootloader like grub2 or the windows bootloader, when "core multiprocessing" was set to "enabled". After the thinkpad boot screen and the LAN ROM message "press ctrl + s to configure", only a black screen was shown and the boot process was stuck.

When "core multiprocessing" was set to "disabled", booting to an operating system worked but only one core was usable. Table loading with grub2 never worked, even with supported dual core installed.


With the modded BIOS, table loading with grub2 is not necessary any more. Booting with a dual core and "core multiprocessing" set to "enabled" works but linux kernel complains about CPU 2 and 3 not responding (only CPU 0 and CPU 1), which is obvious. Booting to the linux desktop is successful despite this error message. But this shows that if 4 cores were available, they would be recognized.

Unfortunately, with a quadcore installed and "core multiprocessing" set to "enabled", booting to a bootloader is still not possible. It is the same situation as with the lenovo BIOS. After the thinkpad boot screen, no image is shown and the boot process does not continue.  With the option set to "disabled", the boot process is continued to the bootloader, but booting an operating system fails with bluescreen (windows) or kernel panic (linux) because APIC table still shows 4 cores but "core multiprocessing" has been "disabled" completely.


I am sure that if the problem of stuck boot process with a quadcore installed could be solved, then quadcores would work in T500 / W500. But I suspect that it is very hard to find out the reason for this, so I do not have much hope regarding this issue.
Maybe there is a piece of code in the BIOS that is executed only when a quadcore is installed and was never debugged. The APIC table with places for up to 4 cores and the q9000 microcode in the original lenovo BIOS show that lenovo might have intended to support C2Q in W500 and T500 but at some point in design process they decided against it and never finished this.

Try disabling the OS detection for switchable graphics and enable the dedicated graphics card only? Maybe it will help, I guess

德国thinkpad 论坛上一位哥们(diablo666)有事相求：
能否将ivb CPU的微码加到t420的bios里?
================================

highsun

T420以后的机器,BIOS修改似乎都是针对每台机器的,无法实现统一修改,我也没有研究过EFI BIOS.目前暂时没有时间折腾.

heimahei

散热压得住，4核不是梦

浪.子

牛逼得很

highsun

基于http://www.ibmnb.com/thread-1437626-1-1.html 修改的。

核对过，只添加了最新的T430s的 microcode

CPUID=206A7
CPUID=306A4
CPUID=306A5
CPUID=306A6
CPUID=306A8
CPUID=306A9

其它未做修改。

刷机有风险阿。第一次改EFI的BIOS，要有心理准备。

T430 原始的BIOS里面是含 206A7 微码的，也就是支持i7-2720QM i5-2520m等CPU的，不知道有没有人尝试过。

金陵老游侠

支持！
不知道能不能把W530的bios里刷入W520的键盘定义...巧克力键盘的手感还凑合，键位实在是受不了

highsun

还没有搞明白键盘scancode放哪里了。

highsun

我记得有人说过把T420的scancode放到T430 BIOS里面了，现在找不到链接。

金陵老游侠

这个比较有意义
前面说的让T420上ivb的CPU好像不止是加微码的问题，据说T420主板芯片不支持ivb。当然，这个也是猜测，看德国人小白鼠做得怎么样了

highsun

我也觉得是。EFI BIOS改变很大。

highsun

可是改了W530的BIOS，有人试么？万一不对，最理想的结果是能用外接USB键盘刷回来。
不理想的结果是彻底爬窝，只能焊下BIOS重刷，我觉得吃螃蟹的人不多。毕竟W530还算半新机器。
大家多半舍不得。
