I'm going to be thoroughly disappointed in myself if that's the problem given how much time I wasted last night. I could have sworn that 1T was the stock setting, but apparently not.

Does 1T vs. 2T make much of a difference in performance? Everything I look up goes back to the DDR2 days so it's hard to gauge. I see the settings you had me use have 1T, so my DIMMs must be crappy in comparison if they can't even run 1T at stock settings whereas yours are doing 1T with a CL of 13.

Edit: Also, my VCCSA is set to +0.220V now, unlike previously where it was stock, so it should be 1.06V once booted.

Large majority of kits on the market are binned at 2T, as per what is specified on the serial label and packaging
post #2123 of 5463
Well since my kit is apparently crappy compared to most of yours, did I just get a bad draw? That is, do you guys buy a lot of kits and effectively bin them and keep the best, such that you all have sets that can run 1T with tight timings? I still can't find any information on 1T vs. 2T (for DDR4) so I don't know if it actually matters, but it is disappointing to have RAM that won't do 1T regardless.

Edit: I see benchmarks showing the effect if DDR4 speed, where these authors are using 1T timings but on Skylake. Perhaps Skylake plays better with tighter timings since the memory bandwidth is so much less due to being dual channel? Or do they just not test their RAM with MemTest so it's probably not stable if they did? For example, see this review:

It could be the IMC, it's not necessarily the RAM.
And more VSA is not always better on this platform, you have to find the sweet spot.

When you say stock settings, did you bump your ram voltage up approximately 25mv to get 1T stable? That set should be 14-14-14-34-2T at 1.35V stock. To get 1T, you need to tweak ram voltage to about 1.37~1.38. VCCSA about .96 ~ 1.05

I would be hesitant to say you got a crappy kit. Some people have spent a lot of time tuning to find the limits of their kits. Most of the people you are referring too with higher clock speeds or tighter timings have higher rated kits than you.

For myself, I would say if you are stable at 3200 14-14-14-34 CR2 1.35V and a reasonable SA, then you got your moneys worth out of the kit.

Not that you couldn't push it further, but I would use that as a baseline.

Got a 3400-C16 16GB TridentZ Kit coming from OutletPC this Thursday(Got it on a 15% discount for $87), let's hope the kit is good and my 6700K can handle it. Otherwise I will probably have to return kit and try my luck with a 3000-C15 TridentZ kit from elsewhere

A better 3200MHz kit than the quad channel 4x8GB TridentZ CL14s? I didn't know they existed, unless you mean people bought faster kits and clocked them down for the better timings?

Hello

I purchase the kits and then tune as needed. Seems that method is not for everyone though.

Exactly biggrin.gif

FWIW, the actual chips in these DIMM's are rated at 2133 by the actual manufacturer(Samsung), and then they are binned by G-skill and sold at whatever speed they could get reliably stable.
