I'm looking for some good memory to go with my 3570k. I am looking for 16GB (2x8) that way I can add another 16GB (same brand and model) down the road. Is it better to go with a 4x4, or since I plan on adding the same brand and model does it matter?
So far I am looking at:
Patriot Gamer 2 Series PGD316G1600ELK (1.6V with 9-9-9-24 timing) - 130
G.SKILL Ripjaws X Series PGD316G1600ELK (1.5V 10-10-10-30-2N timing) - 120
G.SKILL Ares Series F3-1600C10D-16GAO (1.5V 10-10-10-30-2N timing) - 120
Mushkin Blackline Frostbyte ?????????????? (1.5V 10-10-10-27 timing) - 120
Corsair Vengeance CMZ16GX3M2A1600C10 (1.5V 10-10-10-27 timing) - 110
I've used 1.5v gskill, patriot, corsair, and kingston. Generally, avoid the value ram unless you can't afford something better. Low profile with heat spreaders is what I prefer in case you have some interference issues with the video card.
Is there a reason that you want 16gb?
Games do not use more than 2-3gb by themselves. Normally, for the gamer, 8gb is fine.
If it is for 64 bit enabled apps, then of course, more is better.
Do realize that for >16gb, you will need windows 7 pro or ultimate.
If you do want 32gb, then buy a 32gb kit of 4 x 8gb up front.
Ram vendors will not guarantee the operation of non matching sticks.
Ram is sold in kits for a reason.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
Although, I think the problem has lessened with the newer Intel chipsets. Still,
it is safer to get what you need in one kit.
As to which kit, do not spend extra for fancy heat spreaders. They are not needed for 1.5v ram.
A low profile kit like the ares will work better with aftermarket cpu coolers.
DDR3-1600 is the sweet spot for performance. There is little value in faster.
Most vendors are good. Pick your favorite.
Or... Check out the vendor support forum to get an idea of what kind of support they give.
It's always best to get 1.5v memory, but up to 1.65v is considered safe. Frequently cheaper kits run at higher voltages to get more speed without using higher quality parts. Comparing two kits of the same speed, one 1.5v and the other 1.6v, the 1.5v kit is almost always superior.
The lower the DRAM voltage the easier it's on your CPU v-e-r-y long-term. Most of the, IMO waste of money, ultra fast RAM is >1.50v and there's no proof that 1.60v~1.65v does any harm to the (SB, SB-E or IB) CPU; there's been a ton of empty conjecture. The degrading is all done by excessive vCore (CPU voltage) and VCCSA/VTT (CPU IMC) voltage. I personally run DDR3L (1.35v) RAM on my SB-E/X79 and plenty of 1.50v and 1.65v RAM on a variety of Intel based CPUs -- not one damaged CPU from DRAM voltage.
Does Ivy not support it?
No, the IB is Dual Channel and so it supports up to 4xDIMM slots unlike the SB-E/LGA 2011 with its 8xDIMM slots.
Keep in mind, there will be 16GB/stick RAM and initally it will be wacky expensive just like 8GB/stick not that long ago. When 8GB/stick was hitting the consumer market 4x8GB would make quite a dent in your wallet @ $2,000 for 32GB. That inturn made other Intel chipsets with more DIMM slots very appealing even IF the CPUs cost more.
The CMZ32GX3M4X1600C10 is either DDR3-1333 CAS 9 (9-9-9-24) or DDR3-1600 CAS 10 (10-10-10-27). The Vengeance are fine, they run @ Rated but they are not so hot OC 'above' Rated and they have very tall cooling fins (they are not low profile). I have (2) sets of Corsair Vengeance CMZ16GX3M4X1600C9G.
The Patroit kit PGD316G1600ELK should be fine as well and it's low profile but with 1.60v so as long as they stay cool you're fine.
Between the two I'd go the Corsair route as long as they can fit with your HSF.
