triple channel ram in z77

Flashheart · 6 Jul 2013 at 19:34

I'll eventually when funds allow put another 4gb stick to match my triple channel 12 gb set. But in the mean time, with my new ivybridge setup is it worth running 8gb in dual channel or the 12 gb in three slots do you think?

Just a general conencus really. It's primarily for gaming, I'm guessing the difference between single and dual channel will be negligable.

just run 8gb in two slots as its dual channel

three sticks might confuse the board and run in single channel which is slower

you could always try both. but probably 8gb dual over single 12.

I wondered exactly the same thing when I got my Ivybridge 3570k. I posted these results on another forum at the time:-

For some reason sometimes my new Samsung greens dual channel 1600MHz were slower than the old Corsair dual channel 1333MHz. Guess the Samsung has slacker timings out of the box.

Default speeds
(1) 2x 2GB Corsair 1333MHz 9-9-9-24 1T 1.5v
(2) 3x 2GB Corsair 1333MHz 9-9-9-24 2T 1.5v
(3) 2x 4GB Samsung 1600MHZ 9-9-9-24 1T 1.35v

Overclocked RAM and CPU to 3.9GHz
(4) 2x 4GB 2133MHZ 10-10-10-28 1T 1.5v.

Cinebench 11.5 (higher is better)

Lightwave Rendering (lower is better)
Scene1 = 1,000,000 polygon car model with HDRI and radiosity
Scene2 = 430,000 polgons, volumetric render

AIDA64 (MB/sec) - higher is better

Sisoft Sandra (GB/sec) - higher is better

Intel Burn Test (GFlops/sec) - higher is better

Metro 2033 Benchmark (fps) 1920x1080 DX11

Heaven 3 benchmark (higher is better)

you need to overclock that Samsung,1600mhz is a sin

I've settled on 1.35volts, 1866MHz 8-8-8-21-1t now - those graphs were just at BIOS auto timings. Looking at them ago though, what is strange is that in benchmarks the 1600 Samsung did better than 1333 Corsair, but in both rendering tests plus Metro 2033 it actually scored worse!

the Samsung have loose timings at stock though,they can be improved a lot

have mine at 2133mhz 1.55v dram 9-11-11-21-1t timings
