Question PC won't post with 4 ram sticks

[cristian_gabi]

Hello! I have a few question if possible.

I have an old system which has the following components: cpu: i7 6700k, mobo: asus h110m2 d3, and a gtx 1060 3gb

I wanted to upgrade the ram to 32 (since it already had 16 gb). I had two old HyperX sticks and I thought of buying another set alltogether, so I got 4 2-power 8gb sticks at 1600mhz 1.35V (since they were really cheap, I think they sell in bulk or something).

The problem is that for some reason my PC won't post with all 4 sticks. I tried all the slots and sticks individually to see if anything is broken, it worked, then I tried 2x configurations in all 4 dimm slots and it worked. But when I put all 4, the pc won't post.

Now, these 4 which I bought in bulk they say that they are single channel modules. Reading the asus page it says this:

• 2 DIMM: Supports one pair of modules inserted into eithor the blue slots or the black slots as one pair of Dual-channel memory configuration
• 4 DIMM: Supports 4 modules inserted into both the blue and black slots as two pairs of Dual-channel memory configuration

Does the issue come from the ram sticks not being dual channel? But if that would be the problem, why does it work with 2 pairs and not 4?

Should I return them and get two dual channel sets?

Thanks!

Download CPU-Z and check the SPD tab for all four sticks, one at a time if you have to.
Write down the timing and voltage tables shown in JEDEC and XMP. See if there is a common or very close set of timings and voltage. Pick a set, try to set that, then (the trick will be) to see if it will boot after you add the other sticks in on those manual timings if the mobo will keep them.

My assumption here is that the timings are so different that the board can't train a common setting. Matched set of four is best option.

Thank you for the quick response! Here they are, I did some screenshots because I think it's easier.

So what I did is just try two sticks (slot 2 and 4) and the other two sticks again

Please let me know if there is anything else I can show. I'm not that advanced to this kind of stuff.

IDK if you mixed up your links but those appear to be the same sticks of RAM in both shots. Manufacture date is same as well as timings. I would expect if they aren't the same brand the timings should look different as well.

They are the same (I put a different color marker on them so I wouldn't mix haha). The thing is that all 4 are the same brand (2-power it's called), since it was cheaper I got 4 of them (it was like $10 each).

What I said about those two hyper-x ones, those are my old sticks which I just put in a drawer.

Did you read user manual of your motherboard?
Here's what it says:

Due to Intel® chipset limitation, this motherboard can only support single-side
memories when four modules are installed and they will run at the maximum
transfer rate of DDR3 1066 MHz.

Are your modules double sided or single sided?
You can not use four double-sided modules with this motherboard.

When you purchased the ram, was it in a pack of 4? Or 2 packs of two, or were they all just single DIMM purchases. Either way, populating 4 slots can often lead to problems. If these are all single packs, then it's no wonder it won't post.

Screenshots show they are dual ranked.

This.
Your system probably can't run dual rank sticks in all 4 slots.

Thank you for the response! Seems like this is the case. I will most likely return them and get 2x 16GB instead.

Good idea! It will serve you better. Try for a reputed brand, as they will be less likely to have issues.

Nope.
16GB DDR3 modules are for servers (ECC Registered modules).
You need four 8GB DDR3 single sided modules.

I see, so it won't work with two 16GB sticks? In that case I think that I won't upgrade the ram anymore since I couldn't find any one sided modules.
