日本戴尔Precision 17 7770评测–其散热需要改造
| 3
拆卸、升级选项和维护
我们在这台笔记本电脑上看到的第一件事是服务门。用一个塑料工具撬开它，你就能看到一个M.2 PCIe x4插槽。
要继续拆卸，请解开六个固定的十字头螺钉。然后，用一个塑料工具撬开底板，从前面的角落开始。
在里面，我们发现一个93Wh的电池组。它让我们完成了13个小时的网络浏览或超过10个小时的视频播放。要取下它，从主板上拔下连接器，并解开固定它的三个十字头螺钉。
接下来，是戴尔为取代SODIMM而推出的新的CAMM内存。它占用的空间较小，但升级起来却要困难得多。这是因为它是由四颗螺钉固定的。其中两个是用来将CAMM连接器模块安装到系统板上的。有趣的是，如果你喜欢使用传统的内存类型，同样的连接器被用来放置SODIMM适配器。
两者之间的区别是，你可以在笔记本电脑内放置高达128GB的CAMM DDR5内存，而SODIMM内存则限制在64GB。反过来说，它支持ECC内存。就存储而言，你总共有四个M.2 PCIe x4插槽，适合第四代固态硬盘并支持RAID模式。
最后，冷却包括两个热管，在CPU和GPU之间共享。它们被连接到一个长的散热器上，由两个强大的风扇进行冷却。此外，你在处理器和显卡的正上方有两个散热片。值得庆幸的是，显存和VRM是由几个散热器管理的。
despite the common verdict of the Precision 7770, and I agree their performance and design flaws aren’t worth their workstation price premium., but still I ordered one, and didn’t end up returning it. Why? Because on Dell’s Outlet store got one with i9, 64GB RAM, and 16GB A4500 GPU for a relative steal by combining discount codes totaling -81% off, paying $2,100 when sticker price was $9,865!!!!
It has met the needs of my academic research analyzing and training models on large engineering datasets, can even play Forza Horizon 5 at Ultra setting on 3440×1440 widescreen monitor at 60-75 FPS!
The most marketing oriented waste of ressources and money I have seen in recent years. With only 210Watts of AC power available, the mainboard is physically incapable of using CPU and GPU at the same time. Putting this amount of power into components that are half the price will give similar, if not better results. (better because a 4090GPU has a larger baseline powerdraw, and needs to be extra careful to not accidentally fry itself under that flimsy heatsink). This thing is like an 7.2l V8 with a fuelpump capped to 1 Gallon per hour: Overtaking a Big Truck will… Read more »
Can you just upgrade the power supply / wall adapter to 300W+ to get better performance? Also, I understand recent BIOS updates have fixed, or at least mitigated many (all?) of the thermal / amperage management concerns.
