Hello guys!

I just bought these rams (G.Skill TridentZ RGB DDR4-3866 C18 QC - 32GB(4x8) and i just cant run it at 3866 - it goes black screen everytime i try to run it at 3866. I can only run them at 3600. Please somebody help!

UPDATE: I just checked what my ram speed were, and in CPU-Z it says now 1800?? Please help!

My specs are:

Motherboard
ASUSTeK COMPUTER INC. STRIX Z270F GAMING (LGA1151)

CPU
Intel Core i7 @ 4.20GHz 41 °C
Kaby Lake 14nm Technology

1. When I look at all these new RGB "innovations", I can't hep but think of my experience when my 3 kids were all bugging me for Britney Spears tickets ... we were able to get them in advance of going on sale and by the time the concert date rolled around, none of them wanted to go ... Britney was now "uncool" for their age group ... and only little kids were into Britney. Next, everyone had to have an iphone and then, having an iPhone was "uncool". This is the future I see for RGB.

However as indicated the high speed stuff is harder to run stable .....

faster is harder
more sticks is harder
more chips per stick is harder

For a gaming build, I really can't see 32 GB as offering any benefit...and this from a guy who has been...

DDR - Double Data Rate ... 2 x 1800 = 3600

To enable the higher setting, you will need to select XMP in the BIOS and make sure voltage is at least 1.35 Many will tell you that Intel doesn't want you going over 1.20 and how doing so is "ooh scary, scary". Rest assured that Intel has no concerns here .. just look at the certified compatible XMP list. Lower is always better and you should use the lowest voltage possible at your OC, but for XMP 2 compatible kits, the max recommended voltage is 1.5v

I never tried lower than 1.35 - but this is actually quite funny. When i start only using one of the rams, i can run 3866 with no problem. And SOMETIME after shutting down the computer and installing the ram nr 2, i can also run 3866 - and then i shut the computer down again and installed the 3 ram and it did work with 3866 - but it wont run all 4 rams with 3866 speed. What im i overseeing here?

1. Never buy 4 sticks when you can fill the need with 2 sticks. Making 4 sticks run at high speed is a much tougher job that 2 sticks ... the faster you go, the harder it is.

2. Run Memtest86+ on the RAM once working, if it fails get an RMA ... try and get them to send you back 2 x 16 rather than 4 x 8GB

3. Going back to my 1st post ... and make sure voltage is at least 1.35 ..... 1.35 in my experience has worked every time at 3200 but above that you may have to go higher ... especially with 4 sticks.

1: I dont think there is 2x16 on these rams - i liked them very much because of the RGB. Do you think i can get 2x16 on 3866mhz of those? Perhaps there is other RGB with 2x16 on 3866?

2: Im gonna di it now

3: I tried 1.35 and higher, it doesnt work.

For a gaming build, I really can't see 32 GB as offering any benefit...and this from a guy who has been using 16 GB as a minimum for some time. Of course, if you have a substantial video editing load or use other workstation apps but then you's prolly not be using Z270.

As for 2 x 16 GB, I can't recall seeing any units > 3333

On gaming platforms (Z series MoBos), 1) I find it hard to justify anything beyond 3200 and 2) I don't like to go higher than 2 stick because it negatively impacts the CPU OC which is more of a piority than faster RAM speeds.

2. BTW, the tests are typically tin 8 - 12 hours or until you get an error. I'd test in this order...

a. all 4 sticks
b. 2 sticks in primary slots
c. other 2 sticks in primary slots
d. Repeat b in secondary slots
e. repeat c in secondary slots

You could start testing single sticks but that involves 4 tests for each stick for no gain ... doesn't really matter which stick is bad when ya have to get a new *matched* set of 4 anyway.
