我尝试使用4GB RAM在Windows 7（64位）上通过git bash进行git克隆 但是如果我在8GB的机器上试一试，那就很好了。
我输入和获取的内容：
git clone user@url:/rep
Cloning into heverest...

remote: Compressing objects: 100% (38411/38411), done.

Receiving objects: 100% (85868/85868), 303.58 MiB | 1.12 MiB/s, done.
fatal: Out of memory, malloc failed (tried to allocate 521762198 bytes)
fatal: index-pack failed
配置：
[core]
filemode = false
bigFileThreshold = 2048m
[pack]
windowMemory = 2048m
threads = 0
window = 0
deltaCacheSize = 0
我需要做什么？ 我需要在配置中更改什么？
