Samsung 4GB 1Rx4 DDR2 PC5300F FBDIMM Running Hot

sensors|head i5k_amb-isa-0000 Adapter: ISA adapter Ch. 0 DIMM 0:+115.0°C (low = +127.5°C, high = +127.5°C) Ch. 0 DIMM 1: +63.5°C (low = +127.5°C, high = +127.5°C) Ch. 0 DIMM 2: +61.0°C (low = +127.5°C, high = +127.5°C) Ch. 1 DIMM 0: +65.0°C (low = +127.5°C, high = +127.5°C) Ch. 1 DIMM 1: +75.0°C (low = +127.5°C, high = +127.5°C) Ch. 1 DIMM 2: +70.0°C (low = +127.5°C, high = +127.5°C)

The 115 degree chip is the 1Rx4 4GB chip, while the Ch .1 DIMM 0 is a 2Rx4 GB chip and is running cool.

I'm not sure why but these Samsung chips with the 1Rx4 run extremely hot and this is not the only example, I have seen many other servers like this and always thought the chip was in a bad/hot spot of the server but swapping the positions didnt' change anything.

Specs again of the cool/good chip:

Samsung (Made in Korea): 4GB 2Rx4 PC2-5300F-555-11-D0

M395T5166AZ4-CE60

Specs of the bad/hot chip (it works perfectly fine but the heat concerns me that it won't last):

Samsung (Mede in Korea) - no the "Mede" is not a typo, could this be fake RAM?: 4GB 1Rx4 PC2-5300F-555-11-B0

M395T5166AZ4-CE66

The two chips also have a different style heatsink.
