Hi,
I suggest you have a look at http://reviews.gem5.org/r/2087/
In contrast to earlier attempts I’ve seen, this patch properly integrates
DRAMSim2 as a type of memory in gem5.
All you have to do is follow the instructions in the patch.

Subject: [gem5-users] DRAMSim2+GEM5 Error
Hi, I want to use DRAMSim2+GEM5, and the patch of Xiangyu Dong is used. Dong
only supplies the se_dramsim2.py, but I want to use the FS mode.
I modified the fs.py, only adding one sentence below
test_sys.physmem = DRAMMemory(range=AddrRange("512MB"))
the following error occured.
xniu@hec-53:~/gem5_parsec1/gem5$ ./build/ALPHA_FS/m5.opt
