I've been getting great advice on my other questions about my i5-750 gaming build, and I'm hoping to get some more suggestions on my choice of RAM. I'm looking for 2 x 2 GB of DDR3 1600mhz RAM for my P55 motherboard, and price is a big factor. I'm not planning on doing more than modest overclocking. I'm currently looking at these sets (prices after rebates):
A few more questions - how much of a difference will CL 9 versus CL 8/7 timings make in actual usage? Is 1.65v an overvoltage setting for the P55 chipset (is the normal 1.5v?), and will that be difficult to maintain with stability? The first or fifth Corsair sets seems to be the best deals, but do they have a good reputation for actually giving out rebates?
Hoping to finish buying all components this week, so advice would be appreciated soon. Thanks!
I wouldn't say one is definitively better then the other.
Be prepared to wait 2-3 months for the rebate.
Yes tighter timings from CL9 to CL7 would be noticable if you had CL8 not so much between 9 or 7
if you want lower volts i suggest you buy a low voltage set
such as Gskills ECO
Corsair is the better quality over G.SKILL but both are outstanding manufacturer's, so both would work.
Outside of benchmarks, you will not see a "real world" difference between Cas9 & Cas7, not saying that Cas7 still isn't better though. Typically, most RAM will run at looser settings, specially not at stock voltage. My guess is either RAM will default to Cas9 at stock voltage of 1.5V.
Thanks for the answers - I went with the G.Skill Ripjaws DDR3 CL7 RAM, which just went down $5 to $110. I'll be pairing it with my Asus P7P55D-E PRO motherboard, which I also just ordered; should be fun to play around with once they arrive!
