Also, shouldn't you normalize the format and remove the "C" or "C-" in front of the timing on the table, so it look all the same on every entry? 2cents.gif

Done from my iPhone, I'll change them this morning

Found a good explanation by raja on another forum while googling about.

I had it set to 65000 and from all accounts that *could* cause data corruption because the charge in the cells will diminish over time.

Now, any of you bother to change trefi and if so what do you change it too or is it just best to be left on AUTO?

The post is 2013 so does this still apply for DDR4? I take it that it does.

** I have lost some decent gains in maxxmem reverting to auto but hey ho.

Also, If I change from 65000 to Auto then do I have to do another memtest/stressapp??

I also found this http://utaharch.blogspot.co.uk/2013/11/a-dram-refresh-tutorial.html


*** Auto is 11440.

If you're not sure it's best to leave it in auto. Beyond that not sure whatever to tell you. If you're not experiencing problems with the value used then it's likely ok. Also for key differences read the paper on FGR that Praz posted. Best honestly to see what works for you and report if you experience any changes.

Ok no problem.

I was not experiencing any issues I know about on 65000 but I was worrying that maybe some kind of data was becoming corrupted over time that I am unaware of.

I will have a read through that paper though thanks.

Well, I started at the bottom 2133mhz auto since I was working on my CPU OC, I've now moved up to 2666mhz 15-15-15-35 1.200V and the sticks remain at room temp after 6 hours of P95 blend. I wish I could get a manual voltage reading off of this board, I can't get anything off of the cap solder points on the back as it seems to be coated. PCH is still an oven though, its showing 62C under load while the CPU barely breaks 45C.

There isn't an easy way to flag it, that's pretty much the question at hand. As I posted earlier it was suggested by Raja to possibly try suspending things to DRAM that consume a lot of memory.

Morning, guys.
I really need some help and hope someone from here could same me from the headache.
On december I bought a new computer and built on on my own.

I5 6600k
Asus Z170 Pro Gaming
EVGA 750+ Gold
Cryorig H7
Kingston Hyperx Fury 2x4GB 2666MHz
AMD R9 390

Everything was working well until I decided I wanted more memory. So I bought another 2x4GB f2666MHz from Kingston, the same Hyperx Fury.
Since then I haven't been able to use the computer.
After tweaking VCCIO and CPU System Agents voltage I managed to boot windows and even open the browser for a few minutes. And it shows up as 16GB in windows.
I was yesterday the whole day trying to change the voltages to get it to work but failed.

I contacted ASUS customer service and they just copied me an answer I had already found on the internet.
Told me to set System Agent to 1.25V and VCCIO to 1.20V. It doesn't work.
I tried enabling and disabling the XMP and even underclocking the memory to 2133MHz.
Right now all I want is a stable system with the 16GB I bought,

Could someone please help me?

It is possible your new ram is broken.
First you should try your new ram only slotted (remove the old stick of ram), and perform some test to see if you have issues or not, like HCI in the header of this topic, or memtest on a usb stick for a few hours.
Can you also check memory timings and precise voltage with a software like hwinfo64 (you can have memory timings, and DRAM voltage in that).
if there's no issues then you can put your other new ram and probably will need to lower to 2133 and "higher" timings to at least get it workable, then you will work from there

Thanks for answering!
I just removed my old sticks and plugged the new ones and ran HCI memtest 100% with 0 errors. So I think the new memories are also fine.
I really don't know what is the problem with these new boards if people try to use more than 2 sticks of memory. Everything works flawlessly if I use only 2 x 4GB memories.
I guess, I will stay with 8GB of RAM (2x4GB and try to sell the brand new sticks I bought). :/

Well its a really sad day frown.gif i finally received my G skill kit from newegg had to import it and payed fees for importing it and a stick is DOA i tried every single slot on my x99 and nada also on mi z170 board .... There probably isn't much i can do about it right ????

Hi

I was wondering which RAM sticks are good for overclocking and speed/timing. Maybe not one with too crazy of a heatsink so I won't have problems with adding a heatsink (probable h100 series).

was looking at these
