1600mhz or 2133mhz?

[vElectrixx]

This is my $1200 build:

 CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz Quad-Core Processor
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Motherboard: ASRock Z77 Extreme4 ATX LGA1155 Motherboard 
RAM : Patriot Viper 3 8GB (2 x 4GB) DDR3-1600 Memory
HDD: Western Digital Caviar Black 1TB 3.5" 7200RPM Internal Hard Drive
GPU: Sapphire AMD Radeon HD 7970 Ghz Edition 
Case: Zalman Z11 Plus Mid Tower ATX Case
 Power Supply: XFX 750W PRO750W Core Edition Single Rail 80+ Bronze
Optical Drive: Lite-On iHAS124-04 DVD/CD Writer
Operating System: Microsoft Windows 7 Home Premium SP1 (OEM) (64-bit)
System Fans: Enermax T.B.SILENCE 120MM Blue LED Twister Case Fan

Should I switch the 1600mhz 8gb Patriot Viper with the 2133mhz 8gb G.Skill Ripjaws X-Series?

The 1600mhz is $40, while the 2133mhz are $55.

Should I keep the 1600, or should I switch? Is there a major performance difference?

There will not be major increase at all. Stick with the 1600mhz. Also, I'm fairly positive that the 2133 RAM will void the CPU warranty.

Just get DDR3 1600Mhz as it makes virtually no difference when your not using the Intel GPU.

Also may I suggest you look at memory that is low profile as the tall heat spreaders are just gimmicky and get in the way of CPU coolers sometimes.

For example of low profile memory:

Thanks for the tip! I'll swap for that spec right now.

1600mhz to 2133mhz is an about %1.3 in performance. Also your motherboard does not support that speed, so stick with the 1600mhz.

Glad I could help.

I have been buying only low profile memory now as I can't see any reason to buy anything else since these came out. Don't have to measure for CPU heatsink clearance ever, as they are barely taller than the DIMM slot they go into. Cool thing is you could say at a later date re-purpose the memory into a small form factor PC like say a home theater PC and have no worries about clearance.

These from Crucial I linked prior are based off the 30nm tech which uses less power and runs runs cooler than the common 60nm tech(most all other memory today except Samsung.) Its also the smaller chips from the 30nm process that allows for the shorter memory.

These are the only other 30nm super low profile 8GB DDR3 sets I know of at this time:
