Ram Causing Overclocking Failed Error

[InfiniteRetro]

I am at a complete loss. I'm running a standard i7 3770 on a p8z77-v lx board. everything has been awesome but lately I noticed that the ram was only running at 1333 instead of the 1600 ive had before.

Ive updated the bios, ive checked the settings in bios, ive reset the bios as well as moving the jumper on the board and also removing the cmos (for some reason none of this restored my updated bios of 2501 back to its factory which is 0401)

If I have 3 sticks in I can set it to 1600 and its fine. soon as I stick in the 4th, boom it wont run it unless its set to 1333.

I thought it was ram at first so I bought brand new ram to test and it did the same thing. I also thought it was the dimms but its not since it doesn't matter what slot I leave spare as soon as I fill it and try to run at 1600 it crashes (aka boot loop before post)

I love batmaning this stuff cos it feels like im missing something really simple. im going to reinstall all the drivers for my motherboard after this post but if you guys can figure out why its causing the overclocking error when it never did when I had it set to 1600 would be awesome my wife suggested I post here lol

thanks guys

Resetting BIOS only resets the settings, it does not and can't change the version of the BIOS. Have you checked RAM voltage setting from BIOS? You propably need to run it at higher voltage to have 4 sticks running at 1600MHz. Default for DDR3 is 1.5V, you should be safe to run the RAM at 1.6 or 1.65V voltage. If you are using different memory models this might also have an effect.

the voltage I believe is set at 1.5. why would it though after all this time suddenly need a bump? I have a 700w psu to, if helps hehe

Did you update bios before or after you noticed the ram running slower than you thought?

Which ram brand and model number?

run memtest86+ installed on an USB flash drive

set an xmp profile in BIOS if available and try again

its G.Skill Ripjaws F3-12800CL10Q-32GBZL

I did think of doing memtest but on brand new ram that was supported it still did the same issue. also did it with my sons ram to. i did try xmp but it just fails...in fact...if i disable all the cpu turbo options and set it thru xmp which reads it at 1600mhz, it doesn't boot loop, but boots up with no beeps and no image.

it happened on factory bios and updated. could it be anything in windows causing it? i do have a lot of stuff plugged in. 9 hdds total could it be somehow causing it to crash? and what does the overclocking error relate to? the cpu?

run memtest, because the ram controller is integrated in the cpu and could be faulty

just plug in one RAM at a time and set the intel xmp profile

unplug all unnecessary devices

set the timings and frequency manually:
Tested Speed 1600MHz
Tested Latency 10-10-10-30-2N
Tested Voltage 1.50v


Because the standard jedec timings are at 1333MHz the motherboard detects an overclocking issue, if something went wrong. But with the xmp profile it should run without problems. Are there more than one xmp profile to choose from?

so the cpu itself could be buggered? my son has the same chip i could try his?

try memtest first please, but could be the cpu socket pins of the motherboard as well

some ddr3 RAM operate at 1.5v at 1333mhz, but 1.65v at 1600mhz. I would check this in AIDA64
