which memory set is best?

[livinus88]

Hi all,

I am configuring a pc for autocad use. I know I can use a lot of memory on a system like this, which is why I'm going for a 12GB memory kit (6X 2GB).

I have two options to choose from, one being a 1333 Mhz set and the other 1600 Mhz. They cost exactly the same, which is probably because the first one has better access times?

The system:
Mainboard: Asus P6T-SE (X58 chipset)
CPU: Intel i7 930 ( 2.8Ghz )
GPU: nVidia Quadro Fx580
Western Digital Velociraptor
64-bit windows 7


Now I'm trying to find out which memory kit is better:
1)
PATRIOT 12GB Kit (6 x 2GB) 1333Mhz DDR3 7-7-7-20 Viper Low Latency ( PVT312G1333LLHB )

CAS 7
tRCD 7
tRP 7
tRAS 20


2)
CORSAIR 12GB Kit (6 x 2GB) 1600Mhz DDR3 9-9-9-24 XMS3 Classic HX3X12G1600C9

CAS 9
tRCD 9
tRP 9
tRAS 24

Thanks for the help :)

The first one because of the lower latency.

I would say they are equal it is a trade off, you trade latency for speed. I am sure that Corsair memory will operate at the same latency as the Patriot memory if you lowered the speed and the Patriot memory would work at a faster speed if you lower the latency. They probably both have the same DRAM chips on the PCB

I would sugest buying 4GB DIMMs 4GB X 3 if you decide that you need more memory later you wont need to remove 3 DIMMs and replace them with 4GB DIMMs. Your motherboard only has 6 DIMM slots.

For $5 more then the Asus P6T-SE (http://www.newegg.com/Product/Product.aspx?Item=N82E16813131386) you can get the
ASUS Sabertooth X58 LGA 1366 Motherboard (http://www.newegg.com/Product/Product.aspx?Item=N82E16813131665) with SATA 6Gb/s and USB 3.0 for future upgradeability

Haha, "only has 6 slots." Let's tell Intel to work on quad-channel memory ASAP.

Thanks people, I'll go for the first one :)

The 1600 is better. Faster clock speeds definitely trumps slightly lower latencies.

There is a big difference from 1333 to 1600. Especially when you consider triple channel and times the speed by three. 3999 vs 4800. That's almost a whole GHz faster. ;)

1600 is a for sure and the idea of 3 x 4gb sticks also

That's might be right

lots of good info :) I used these guys to build me a computer and found out they put in Patriot memory which has worked so well for me.

The main system:
Mainboard: Asus P6T-SE
CPU: Intel i7 930 ( 2.6Ghz )
GPU: nVidia Quadro Fx580

Probably the one with the lower voltage rating, but be very suspicious of any DDR3 module rated for more than 1.50V (no chip manufacturer specifies a higher nominal voltage) or that doesn't have the chip maker's logo or full part numbers clearly visible on each chip, unless the whole module was made by a real chip manufacturer.

Test any memory you buy very thoroughly overnight, at its stock settings (no tweaking of voltage or timings), using both MemTest86 (or the very similar MemTest+ but not MemTest) and Gold Memory. Try to test with every combination of modules and sockets, that is, rearrange the modules and test individually and together. Unbranded memory, which is what Patriot, Corsair, G.Skill, Kingston, etc. primarily use, is pretty bad.
