Big difference between cl9 and cl10 ram at same frequency?

[PaulG]

Hello,

I am planing to buy the Kingston HyperX Fury 1866mhz cl10 8gb dual kit.

Is there a significant difference between cl9 and cl10 kits for gaming at the same memory bandwith?

Thanks.

Lower CL = better performance

Specifically by how much, I can't say. Haven't looked up how the math works in a while.

IIRC though, it's a pretty insigificant difference between something like 9 and 10.

If it was 7 and 11 or something, then it'll probably be more noticeable.

You will notice exactly 0 difference between the two. Get whichever is cheaper.

We're talking nano seconds worth of difference between the two, so it's negligible.

Lower CL = better performance

 

When comparing the same generation DDR memory with the same clock rate, yeah; but not always the case if one's clock rate is high enough.

You will probably only notice a difference in memory heavy benchmarks.

 

At the same memory speed a lower CL is better, but not if it costs extra.

1600 cl9, 1866 cl10, 2133 cl11 will all perform about the same. All this stuff is the same ram with timings changed and a voltage bump.

 

If you can get 1866 CL9 for the same price go for it. If a 1.5v CL9 1600 9-9-9-24 is cheaper? Buy that. It will do 1866 CL10 in a heartbeat and can usually do like 9-10-9-28. 2133 cl9 is probably as good as it gets for gaming, but not worth paying for. Maybe .5 FPS in only some games. 

 

By whatever is cheapest, change T3 to T1 and you are pretty much set. Past that you can spend a ton of time memory testing, and you can check bandwidth with maxmem or AIDA but it doesn't mean much outside a synthetic benchmark.

 

This 64 bucks atm. Gskill 1866 CL9. The timings are pretty much ideal and already set for you. If it is cheaper than the Kingston. Grab it, enable the XML profile then change T3 to T1 and you are done. If you are bored you can also try for CL9 2133 on it, and can most likely get cl10 2133 (will perform almost the same). Gskill makes quality stuff.
