One more question:
What defines the boundry of possible range then?

Call Timing Table Editor, set focus on the "Min CAS Latency Time" listbox and scroll up/down with mouse wheel until the DefCAS field changes to another CAS. And you'll get the possible range.

Sorry looks like i ask the qeustion the wrong way.
What i do not understand is that the RAM runs ROOCK STABLE at 8.656 ns (CL9/69) with T1 command rate but won`t boot at all at 8.531 ns (CL8/68) with T2 command rate and even witch all other parameters much looser. Thats just a difference of 0.125ns...
Same with the tRCD it is stable at 9,781ns (10T/78) (as 9-10-9-27), but won`t boot at 9.656ns (still 10T/77) even if i raise the whole thing to 11-10-11-34?
It feels more like running into some artificial wall than really reaching the technical limits.
Thanks for your patience!

Prema, I assume that it won't run at CL8 because it means 8 tacts for 8.531 ns. I don't know this for sure but think that it means 1.066 ns each tact. But when you choose CL9 8.656 it will work at 0.962 ns each tacts. Your RAM needs at least 9 CL tacts on certain speed. while chips are so ROCK SOLID that they may work easily (perhaps) on the fastest possible speed of 1 tact which is 0.962 ns.

I just think hat I'm right but I may be fully wrong.

That indeed makes a lot of sense for the CAS!
Still wondering about the tRCD which remains within 10T and still refuses to boot no matter how slow i set the rest...

OH MY GOD, 18 pages about one product and not one real world benchmark is contained in here.

I would be one of the people telling you that unless your using a integrated GPU there is no reason to have faster ram than what comes stock with your laptop and rather than say that since HT already tried to, I wanted to see the benchmarks but nobody has posted any...

Wonder why?

Yeah it started be boring for me too som module modding for 3% cant be arsed..
And benchmarks? I think i have posted som ( depends which u wanna see) winsat shows 24620 MB/s same as the kingston no diff. at all

I think what Vicious meant was real world usage benchmarks, for example, running games and checking min/max and average fps. I've seen some claims in Asus gaming that faster RAM helped keeping the minimum fps a little higher, if that is truly the case, then the RAM may be worth it to some.

Yes this. RAM benchmarks don't tell us much. When I became interested in SSD's all I saw were SSD benchmarks and nothing more. Once you get to real world usage you would see for your average consumer the "slow" SSD's performed just as well if not better than the "fast" SSD's.

Please offer some gaming benchmarks before/after comparison would really tell us something. Even a run of 3DMark Vantage and 11 at 1333 and 1866 if nothing else. I'll even provide links to reasonable gaming benchmarks if desired.

HyperX 1600Mhz PNP





I'm running



Will do a few vantage runs later but need to wait till it's minus outside cause I'll be pushing the cpu for 30k

But I want Vengeance 1866!!!

James D,

Here is the link to the datasheet on Micron D9PFJ chips:
MT41K256M8DA-125 - Micron Technology, Inc.

Perhaps, you'll find it useful for your first post.
