DDR3 Week Round-Up

Test Rig:

All of the RAM sets were tested on the same computer, with the parts listed below:

CPU-Z:

CPU-Z isn't exactly a benchmark, so there's really no "who's better than the other" here. Below, we've posted the CPU-Z images for all 6 products for each frequency. Refer to the individual product reviews if something you see doesn't make sense.

Kingston 1375	Corsair 1600	Kingston 1600	PQI 1600	Super Talent 1800	Patriot 1800

MemTach:

Higher numbers are better.

Model:	memset 1375	memcpy 1375	memset 1600	memcpy 1600	memset 1800	memcpy 1800
Kingston 1375	2351.4	1872.9	0	0	0	0
Corsair 1600	2410.6	1928.4	2443.3	1938.5	0	0
Kingston 1600	2403.2	1866.3	2469	1926.2	0	0
PQI 1600	2413.6	1902.1	2296.8	1875	0	0
Super Talent 1800	2360.5	1878.4	2429.3	1910.9	2344.2	1798.7
Patriot 1800	2402.3	1924.8	2452	1934.3	0	0


memset	memcpy

As you can see from the graphs above, the PQI RAM seems to lead in the memset 1375 test, but drops to the bottom for the memset 1600 test (since the Kingston 1375 can't be tested at that frequency). The leader in memset 1600 becomes the Kingston DDR3-1600 kit. Memcpy 1375 starts with a nice lead from the Corsair DDR3-1600 kit, and stays strong through the memcpy 1600 test as well. We notice in the 1800MHz test that the Super Talent RAM has a severe drop in performance, even below the 1375 test. Our Patriot kit wouldn't operate at a FSB of 1066, so the results were not included to be fair.
