iPad generation RAM expansion service appeared in China

Recently, the reporter discovered that there have been domestic Apple product repair shops began to provide users with the iPad's RAM upgrade to 512MB service. According to a survey by the reporter, the principle may be to replace the original A4 chip with the A4 processor in the iPhone 4. According to some of the upgraded consumers, they said that their iPad has been updated through a program and the RAM value has indeed been upgraded.

The first thing to tell the general reader is that the concept of RAM and the memory in the mobile device is basically the same. It guarantees the fluency of the device running tasks and provides effective support for multitasking. Currently, Apple's iPad 2 has a RAM value of 512MB, while the generation of iPad has only 256MB, and this level is equal to some low-end Android phones on the domestic market. As a result, the iPad generation is prone to caching or flashback when working with multiple tasks and browsing multiple web pages.

Recently, the reporter discovered in the maintenance network of some Apple devices in Zhongguancun that some domestic merchants have begun to provide expansion RAM services for iPad 1 users. They can expand the original 256MB of RAM to 512MB, and the price is generally 600. Yuan around, and the entire upgrade time is about 2 hours. At the same time, the merchant also assured the reporter that the RAM upgrade will not have any impact on the quality of the iPad. The user's daily use is completely normal, and the capacity expansion of RAM can also be found through some application tools.

According to the store's owner, there is no need for the user to replace the motherboard during the RAM upgrade of the iPad generation, thus ensuring the success rate and the stability of the iOS system to some extent. However, the reporter learned from previous iPad data that the iPad's DRAM chip is actually built into Apple's A4 processor. Although the store did not disclose the specific upgrade principle, but the reporter speculated that the current A4 chip in the iPhone4 has a built-in 512MB DRAM chip, and if the store replaced the original iPad A4 processor for the iPhone4, then it can guarantee With the CPU configuration basically unchanged, the RAM value can be doubled.

In addition, at present, there is a phenomenon that A4 processors are sold separately as maintenance parts. Generally, the price is about 200-300 yuan, and some businesses also tagged the iPad along with their products. In addition, it is not necessary to take such a long time to perform the replacement of the entire main board in view of the two-hour maintenance upgrade of the upgraded store.

The reporter also learned from some consumers who have already tried to upgrade that the upgraded RAM value of their mobile phone's iPad has indeed been improved, and the system has become more fluid in its daily use.

However, it should be noted that if, as the reporter guessed, the replacement of the iPhone 4's A4 processor is true, then the iPad's CPU speed may drop, because the iPhone 4's clock frequency has been limited to 800MHz by Apple, and It is not 1GHz that is mentioned in some propaganda. Of course, Apple's CPU frequency setting for the device has also adopted a firmware lock method. The 800MHz clock frequency may also be restored to 1GHz speed under the iOS iOS firmware control.
