[SOLVED] High frequency ram not working ??

[VickyTech]

I have a lenovo e41-15 laptop which supports upto 1600mhz 8GB ram. But i bought a 1866mhz ram instead of 1600mhz. When i install this ram the laptop is not booting. I thought the ram will be downclocked to supported frequency. I installed the ram in another laptop which supports high frequency ram (1866mhz ..maybe more) it is working fine. Why it is not working in my laptop??
What should I do to run the ram in my laptop ?? Help me please !!

I think that as long as you cannot boot your laptop with the 1866 MHz RAM, you can’t clock it down.

As your laptop specified on it’s own, it can only support up to 1600 MHz RAM. The only solution is to get your hands on 1600 MHz RAM

I found that laptops usually don't have an option to adjust ram speed in bios. But it should automatically downclock the ram right ? Thats what I found on the internet. But I don't know why my laptop is not doing it ! Anyway Im going to get a 1600mhz ram. But i just want to why it is not downclocking automatically?

It could be you laptop doesn't like that brand of memory, Crucial's memory for it is low voltage 1.35 volts. What did you buy?

I bought a ram with same specs as crucial's (Brand - Zifei).

But since my processor supports upto 1600mhz of ram it is not working in my laptop (I guess my laptop doesn't do downclocking).

It's probably not downclocking because it NEEDS to boot first. If it doesn't boot, your laptop can't acces the bios to downclock it. Software is needed to downclock RAM. It's either that or your laptop just doesn't like the brand, as lynx1021 stated earlier.

You said "I bought a ram with same specs as crucial's" That is not correct because Crucial does not publish all it specs that a person would need to match it up to another brand. They don't tell you if it Rank 1 or 2

I understood. I checked amazon's customer images section for crucial's product, where cpuz shows Dual Rank. The ram i bought is also a dual rank ( 2R×8).
Many say that single rank memory is faster than dual rank. But almost all brands including crucial and samsung sell only dual rank modules. I can't even find a single rank module in amazon.
