Gigabyte Z490 Aorus Elite Ac memory compatibility issues/bsod

it wont boot with single stick in A1 try a single stick in A2 for post
Have just tried with ddr4-4400 19-19-19-39-69-1.45v in slot A2. And it boots into windows. This is the highest memory profile. Not sure on stability but it boots. Im going to test the other sticks. But its interesting it won't boot atall in slot a1 with the xmp 4400?
 
try them in pairs, first kit using slot A2 and B2 run system and check for stability, then swap the kit over using the same slot, then try all four with manual voltage

Will give that a go now and report back. Im begining to think there was possibly a mistake and they sent different ram kits?

So tried the pair that report 1.45v in 4400 profile. In the slots you suggest and works fine. No crashes. I will test the other two sticks that report 1.65v in the same slots. And see if that works. Could it be faulty ram? Or possibly faulty slots on the motherboard? Is there any reason for it not to post using slot a1?

So I tried both pairs in the slots you said and works fine. All sticks. Could the motherboard be faulty if slot a1 isn't working? I will try installing dual rank in slots a1 and b1, see if it boots. Im hoping it's just the motherboard applying incorrect voltage. Think I'm getting somewhere though.

to add to this, will not post in solts a1 and b1 with xmp 4400. However the xmp reports 1.45v which is correct? But will not post. Does this indicate a faulty motherboard? Could the cpu have anything to do with memory? Could it be the memory controller inside the cpu?

okay, so to update this. all sticks of ram work fine in slots in slots A2 and B2 at xmp 4400. when i use slots A1 and B1, it will not post with xmp 4400 (profile 1). it will post with xmp 4266 (profile 2) so with all sticks installed it seems stable on profile 2. profile 1 works only in slots A2 and B2, and profile 2 works in slots A1 and B1. profile 2 will not work in A1 and B1.

does this point to a motherboard issue ? could it be the cpu memory controller ?

Possibly cpu can’t cope with running 4 at that speed, I would run them all at 4266 and tighten the timing a bit maybe 18 18 18 39, the memory is working fine at 4400 in a2 and b2 so the memory isn’t the issue, some cpu can’t run all 4 at full speed as the memory controller can’t cope with it, you will normally find you can get faster running speeds when only using two sticks. To be honest you won’t really notice much difference between 4266 and 4400, glad you have it all running thou and bet you are seeing some solid FPS increases across the board

Hey there,

Finally got some time away from work.

Trouble is. The system isn't working. Even without xmp profiles enabled. I was playing some borderlands 3 last night with the wifey. And the system crashed 5 times, even without xmp profiles enabled.

Im doing a mem test now, and so far on pass 1. It's found 1305 errors.

I really cant figure out if it's the memory. Motherboard or cpu. But either way there's a big problem here. You would think if you buy new components. They'd work together. Having checked the motherboard support page for memory. It clearly states my memory is supported.

It failed on test 7 moving insertions 32 bit patter and gave me 1305 errors.

It's doing random number sequence now and that's given 5 errors.

Edit.... To add. Im not seeing any gains over my last system. The frame dropped from 120fps to 92 fps. Same gpu aswell. All that changed in my system is the cpu memory and motherboard. My old z87 platform with a 4670k @4.2ghz was much better than this.

it is looking like you have some faulty memory, try running mem test with only 2 sticks, if successful swap the kit over and test again
Will give this ago when I get back. Some one else suggested just get the ram rma'd. I've never had to do this. So I don't know the process or how. Seems its a headache.

I would contact the place of purchase and order another pair and return the other pair for a refund, that will be your quickest turn around. You will probably find that one of the sticks is faulty, you have just been unlucky with one of the kits you have received. I personally cant remember the last time I had faulty memory that was new it was a very long time ago. once you have identified the faulty kit you can continue to use your computer with just the 16Gb installed until the new memory turns up. The RMA process is normally straight forward thou you just contact the manufacturer with you details and copy of the receipt with photos showing the errors and send it back, you normally receive the new ones very quickly.

This is a good point. Hopefully. Not all sticks are faulty.

Trouble is I got this from over clockers on thier buy now pay later scheme, so not sure how it works with refunds with this.

But I will test each kit/stick individually. Hopelyy one kit doesn't have any errors, and i can send one kit back like you said.

Fingers crossed that it is the ram and not cpu/mobo combination. Ive never seen ram this bad before.
