ram settings in bios

timbo2410 · 11 Dec 2015 at 14:12

My ram is showing up as 2133 mhz when it is actually 3733mhz ... now do I just use the ram info to alter the bios settings to get it to run at the rated speed? Never done this before:
Ram: 16GB(2x8gb) Team Group dual channel DDR4 3733 (18-20-20-39) at 1.35v

anybody

look in the bios for xmp,then enable it/select profile that gives you rated ram speed

it will set correct speed/timings/voltage for you

thanks

nope no go, xmp puts in all the correct values apart from the first. Instead of 3733mhz it puts in 3731mhz .. the timings are correct and so is the voltage. Cannot boot into bios after re-start. Have to reset to bios safe mode and changed back to boot. Error comes up as "55" - no memory detected.

could it be anything to do with the two sticks of ram in slots 2 and 4 as the manual suggests? I've always used slots 1 and 3 as instructed prior to this ??

just ran a windows10 memory test and all appears fine on that ??

What is your system spec. It sounds to me like you cpu don't like the speeds or you cpu is over clocked be for you put new ram in? Do a full bios reset then set xpm.

1 and 3 will work just the same,its usually 2 and 4

latest bios? you might need more memory controller voltage no idea what it is labelled as on x99/z97 and onwards though

timbo2410 · 12 Dec 2015 at 19:33

already done reset. All a new build. Specs are:

Case: Phanteks Enthoo Primo
mobo: Asus Maximus viii Extreme
cpu: Core i7 6700k
Cooler: Corsair H110i GTX
Ram: 16GB(2x8gb) Team Group DDR4 3733 (18-20-20-39)
SSD: Samsung 850 Pro 1TB
GPU Asus GTX980 Ti Matrix
PSU: Corsair 1200W
Optical: Pioneer BDRW
Nothing is overclocked. Windows 10 Pro is up and running and all software and drivers installed.

I've checked and I'm about 3 or 4 bios versions behind current. Should I go for latest?

wazza300 · 12 Dec 2015 at 19:43

yes I would,use usb stick and flash through ezflash within the bios

timbo2410 · 12 Dec 2015 at 19:44

no usb stick can I do direct download via internet in bios

wazza300 · 12 Dec 2015 at 19:52

can try it,should be fine

timbo2410 · 12 Dec 2015 at 20:36

ok updated to latest. Checked ram and it's still reading low timings and speed. I have ASUS memtweak running, is it worth altering the settings there on the desktop or go back into bios?

timbo2410 · 12 Dec 2015 at 20:38

actually thats no good because I can't put in the ram speed anyway, so it will have to be bios ..

wazza300 · 12 Dec 2015 at 20:43

it depends on the cpu/memory controller

it wont match the timings exactly unless you tune the ram/adding more memory controller voltage

timbo2410 · 12 Dec 2015 at 20:54

ok. I'll go back into bios and manually set the speed, timing and voltage. Everything else I will leave in auto ..

wazza300 · 12 Dec 2015 at 20:56

its not dram voltage its another one for the memory controller

system agent, im not sure on that platform though,you might need two or three clicks more than what auto uses,maybe someone who knows more can help with that

timbo2410 · 12 Dec 2015 at 21:02

i'll wait before I touch anything then. I did try on the ASUS forum but I've gotta wait two work days for registration :-(
