按楼上的配置升级了:1.CPU由T5550升级成T8300，41元(本想升T9300要120元，太贵)；2.内存条由两条海力士1G-667MHz换成两条金士顿2G-800MHz，60元(中途买过便宜的但开不了机退货了)；3.硬盘由120G机械换成了120G固态78元，(网店上最便宜的一款，本想买240G西数，想下升级没比要花太多钱)；买了个硬盘盒装原来机械硬盘当移动硬盘使用，27元；4.网卡升级Intel-5300，20元；5.买了0.3mm厚紫铜片改造散热，0.1mm厚石墨片公司的打样材料，取消显卡和北桥的散热泡棉垫，用两片紫铜片替代，规格(15*15*1.5mm垫显卡芯片，15*15*1.2mm垫北桥芯片，中间的所有接触面涂上薄薄一层导热硅胶，我是用的手机的散热硅胶)；(内存条和固态硬盘两面贴石墨片改善散热，散热器用锡线焊接0.3mm厚紫铜片，主要加焊显卡端到风扇口，再用石墨片贴在表面；0.3mm厚紫铜加焊不容易顶后盖，改造完用鲁大师压力测试3分钟显卡和CPU都不会超80度(夏天室温32度)；6.系统换成了Win7-64位(老的系统识别不了4G内存)；总共花费235元。
你这个本内存已经插满了，这个本最大支持两条2G DDR2，就是最大4G，如果已经是4G那就没必要升了，CPU最大升级到T9500，T9500现在淘宝好到200块了，性价比不高，T9300是70左右，个人觉得T8100和T8300更适合升级，一个是十块一个是二十块。T8300相当于台式机奔腾E5200，T9300相当于E5300，别看二级缓存翻番了，但是差别不大，T8和T9都是45纳米，发热量低，比有些人说的T7700好多了。另外，m1330本身散热就不好，不适合用65纳米的cpu，况且，你这个是独显版本。Geforce 8400M GS当年好多因为高温出现六分屏，黑屏，所以更建议用T8300，性价比最高的选择。如果之前cpu主频不低于2G，我建议不要升级了，没必要，这个本都产了11年了，当年我买这个本也是买的独显，主板都换了两块，现在用的集显主板才勉强撑到现在，平时也只能用来上上网，看看电影，玩个跑跑卡丁车，打个拳皇而已。没有太高的升级的必要了。最后附加两项，换固态硬盘和无线网卡，原来机器的机械硬盘太慢了，换个固态硬盘比升级CPU还有用，另外本来机器带的无线网卡是54M的无线网卡，有线是百兆，应该换个好点的无线网卡，我换的是intel 5100.因为我用的是LED屏幕，所以只有两根天线，所以只能换5100，如果你不是LED屏那就是三根天线，可以上intel 5300，现在网上20块钱包邮。
可以参考以下：
CPU -> T7700 (此款CPU为PM965主板最高适合，T9系列不适合此款主板)
内存 -> 最高4GB
换固态硬盘，原硬盘可放在光驱位置作副盘，光驱拆下。
换掉这些，你的XPS再活个3-4年，应该不成问题。
注：此款CPU是可更换的，本人已按上面的配置升级完毕。
首先你要确定处理器是可以拆卸的 其次你要知道自己电脑内存是几代的
