Picking ram for i5 2500k

post #1 of 6
Thread Starter 
I'm very familiar with Ripjaws, and was looking to buy Ripjaws X series. a few questions. Buying ram at 1600.



1) Which 8 GB do you recommend for photo editing? Or should I get a 4 gb with lower timings?
For the 8 GB ram, I can get the DDR3 1600 w/ lower timings
http://www.newegg.com/Product/Produc...-445-_-Product

or the higher timings but 1866 speed
http://www.newegg.com/Product/Produc...82E16820231455

Building two comps, one with 4 gb ram and one with 8 gb. Both i5 2500k's with hyper 212 + in CM 690 ii advanced, it'll fit right?

Should I get 1.5 or 1.65v? Is there a major difference? One mobo will be asus p8p67 pro and one gigabyte z68xp-ud4

I have a G.Skill Sniper (2x4GB) @1.5v with my mobo (asus) and it is working fine. XMP'd to 1600Mhz @1.5v (stable with IBT. I'll use memtest when I have can afford an empty disc ) and will test at 1866Mhz later. Generally, I would say go with lower voltages so you *may* have more voltage raising headroom without frying your system. However, many other factors affect voltage tweakability of the ram.
Lower voltage will also correlate directly with less heat.
I would definitely go with 8GB ram though timing will be another factor to look at. The extra RAM will come in handy in photo editing for the most part though I doubt 4GB will suffer at all. 8GB @ 1600Mhz and CAS 9, should be fine.

Hmm, The RipjawsX @CL9, 1866 will have about a 9.6ns response time whereas the 1600 @CL8 will have a response of about 10ns. The timing of 9-10-9 throws me off a bit so I'd say it should be anything between 9.6ns and 10 ns. Generally, I'd expect the 1866 model to perform faster though you will probably not notice the difference much anyway

For overclocking i5 2500k the rams that mylilpony has on his first post on this thread
would the 1600 cl8 be better or 1866 cl9 for overclocking on a sabertooth rev 3
im afraid it might be not stable and i will need to increase the ram voltages for 1866?

Well, I didn't touch my RAM voltage (still at 1.5V) and my 2500k is overclocked (see sig) and passed 20 tests with IBT @ the Maximum setting so I dare say you shouldn't have to raise the RAM voltages for that overclock. However, i'm not exactly a RAM overclocking pro so this is juts my $0.02. Generally, whatever the RAM's speed/timings and voltage are, it will run at that stably.

I have seen people suggest that you go with more loose timings for overclocking and then tighten them yourself as you OC...

I have a day off tomorrow so I'll push my RAM to 1866 and see how stable it is with minimal voltage tweaks. Will post back results.
