Unable to run ram at max speed

[Samrezkhan]

Hi There Everyone.

I am unable to run my ram at the maximum speed which is 1866mhz
Here are my system specs

Processor: i5 3570k with stock cooler
Motherboard: P8z77- V LK
Ram: Gskill ripjaws F3-14900cl10s 1x8gb
Psu: VS550 watts
Gpu: Yet to install
Casing: Cm Storm Sniper

This is my first build and I cant run the ram at max speed.Yes I know my build is outdated but I live in Pakistan and prices for every item is almost a 100% extra.

Now back to the question, I have the updated bios version. I have tried the xmp settings and rest all on auto, but it doesnt go beyond windows startup and always shows "system occured with a problem" and goes into system recovery.

It is only running at 1333mhz, any speed higher doesnt let it run.

I tried putting the speed in manually, which didn't work either even the voltage to 1.55v. (but i dont know where are the rest of commands like tcr to 2t etc)

I have tried different slots but the case remains same.

Any help will be highly appreciated.

It sounds like a bad stick, so it's defaulting to the slowest speed.

I would RMA the stick, and if possible get another identical stick or replace with a kit with TWO sticks instead (such as 2x4GB 1866MHz).

TWO sticks in Dual-Channel (must use recommended motherboard configuration) double the bandwidth between CPU and Memory compared to a single stick.

For most things 1866MHz on a single stick is fine, though probably 1333MHz you're losing some performance. It's very hard to be specific as it varies a lot.

Hello Samrez,

You need to use the xmp (intel extreme memory profile) profile.

edit : my bad, you have already tried xmp profile.
thanks to photon master for correcting me.

Check your BIOS version, I know you said it's the LATEST so ignore if this is true. If it's older than 1402 you should update it. (check while in BIOS or use CPU-Z)

v1402 adds support for newer memory, though you may still have a bad stick.

1. click "others" for OS

2. download 1402 BIOS, and bupdater

3. follow MANUAL instructions to flash to 1402 BIOS

It is already at 1402.

ok something to add

I just put ram to 1.65v and it ran at 1400mhz, though it is nothing but I havent tried it at higher speeds yet.

Lets see what that gets me
