Is the extra money worth it, or should I use these cheaper sticks?

I'm building my first PC. I've got all my components already, or they're on the way, except for the RAM. I want to use the Gskill Eco series, but they shot up to $125 or so, after shipping. My question is, are they worth it, or would the cheaper RipJaws do the trick. I'll spend the money if they're worth it. The lower voltage would mean less consumption, heat, and stress on my system. Again though, is it worth it, or would the benefits be minimal?

This is my rig:

Asus P7P55D Pro
intel i5 750 Lynnfield
Corsair 650HX
CM Storm Scout case
Sapphire Radeon HD 6850
Windows 7 64
CM 212 HSF

These are the sticks I'm looking at. Which one would you buy, and is the disparity in price worth it?

(1.5 volt 9-9-9 timings) - Only $93.99
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
http://www.newegg.com/Product/Product.aspx?Item=N82E168...



G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 - $104.99
http://www.newegg.com/Product/Product.aspx?Item=N82E168...



Timing 8-8-8-24-2N <> Voltage 1.35V - $121
G.SKILL ECO Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600
http://www.newegg.com/Product/Product.aspx?Item=N82E168...



Timing 7-8-7-24-2N <> Voltage 1.35V = $126
G.SKILL ECO Series 4GB (2 x 2GB) 240-Pin DDR3

Any and all advice is appreciated. Thanks.

Are you going to overclock/adjust your CPU so it can run the ram at 1600MHz, or are you going to run it at 1333MHz? (at stock speeds, the i5 750 has a max memory speed of 1333MHz).

If you do run the Ram at 1333MHz, then the first set may be fine as you may be able to get the timings down to 7-7-7-21 and keep the low 1.5V.

The Eco does look really nice, but a $20 price jack is pretty high for a small benefit.

Yes, I do plan on OC'ing the i5 750. That's why I want 1600 mhz.

One question I have is whether or not the first RAM listed, the Ripjaws for $94, will cause any problems with other components physically fitting in my case. The other sticks are al low profile, but the cheaper Ripjaws are not. Think that's a problem?

Depends on how close the RAM slots are to the CPU. On my board it would have been close, but I think Asus gives you a little more space.

Ignoring the potential for not fitting, there will be very little (if any) noticeable difference between the higher and lower timing sticks.

1.5V is the spec, so it will run cool and safe, though obviously the Ecos will run a little cooler,

So I take it you think I should save the $30+ dollars and go with the $94 Ripjaws?

That is probably what I'd do if just looking at realistic Performance vs. Price. i can't find any comparisons offhand, but if you do searches for something like "DDR3 timing benchmarks" etc. you should be able to find some reviews so you can see how much faster timings will help and whether it is worth the higher price. I can tell you now though that in just about anything but benches the tighter timings will not help much.

Thanks bud. BTW, I just noticed we've pretty much got the same system build. How's the i5 750 & Radeon 5850 treating you? I'm very excited about putting mine together, and seeing what it can do. I'm currently using an Athlon 3400+ with a 128 MB 9550 SE. I'm guessing the improvment I'm going to see will be something else.

I ordered the Ripjaws. They actually went on sale too, so they were $84.99 with free shipping. Thanks for your help EX.

Well, compared to your old system, unbelievable. In general though it is running great, though I have gotten one Grey Screen of Death (however, at that point Crysis was really acting up and seemed to have a memory leak). The card and processor run very cool and very fast.
