Ram timings and Speed

[HardwareGeek]

Hey guys,

Long time lurker on these forums but just got registered and this is my first post.

First off just want to say this forum is great, easily the best i've ever found, people here are so helpful and knowledgeable.


So, my question is:

Basically general performance and best possible timings of different ram kits


I know ram now makes very little practical difference in the last few years since cpus have intergrated memory controllers, so this is more a hypothetical question i guess.


Another thread got me thinking which type of ram would give best timings and performance over a wide MHz range


For example type A vs. type B below

Type A = 16000C9 2000MHz 9-9-9-24

Type B = 12800C7 1600MHz 7-7-7-24

So in certain situations which would perform better?

1) For example would the 2000 MHz run the tighter timings of the other kit if it was run at 1600 MHz?

2) Would the slower kit reach 2000 MHz with better timings than the faster kit or the same timings or would it struggle to reach the same specs?

3) For a standard i7 over clock speed which kit would reach the required MHz speed and give the best timings? (Guessing tighter timing kit here)


I guess a lot of what i am asking would be to do with the binning of the memory chips on the ram and if they are specifically binned for high MHz or tighter timings.

Hope this makes sense and apologies for the long post.

Thanks v much guys

The 2000 kit should easily run at 1600 with timings of 7-7-7 or better. The 1600 probably won't reacj 2000 at under 1.65v which is what is important for i7's. The best kit to go for would be the 2000 kit without a shadow of a doubt.

e.g. I have 1600-7-8-7 kit and it takes me 1.67 to run at 1900-9-9-9. A 2000-9-9-9 kit would easily run at 1900-9-9-9 at under 1.65v

Thanks for the reply.

I think what you said is right and i had forgotten about the voltage limit on the memory controller and possible damage from higher voltage.
