[I CONSIDER IT PRETTY MUCH SOLVED, NOT MUCH NEED FOR MORE INPUT]

Hi,

I bougt a second hand gaming pc not long ago, because it was pretty cheap.
Acer predator orion 3000.
Motherboard: Po3-630
CPU: i7-11700f
GPU: RTX 3060 ti

and it came with 32 GB ram, ddr4 and was in the form of 4x8, so all 4 memory slots used.

I found some good offers on ram in the second hand market and bought 4 sticks with 16 gb ram each, so 4x16 GB ram, all ddr4, 3200Mhz corsair vengeance LPX, all 4 sticks.

But after I replaced the old sticks with these new/used sticks the pc does not boot. Well, power is on, but the monitor says "no signal" and the computer starts making a fairly loud sound, like a long continous "BEEEEEEEEEEP...."
Something I have never experienced before.

I did use the computer before I found and tried to install the new ram, so I know that the computer with its old ram works perfectly well, no trouble at all. So it seems clear that something must have gone wrong with the installation of the new ram.

I am no experienced pc builder at all, but I am a decent patient researcher and looked up guides before I started this project (and many places people stressed that installing ram should be one of the easiest 'operations' in pc building, so I did not feel worried). I also looked at other threads around the web with other people having similar problems like me and tried to go through some of their troubleshooting steps and solutions, which did not help, which is why I now ended up here.

I did research before hand that my setup should support ddr4, 3200Mhz and up to 64 GB ram.
What did I actually do:

1) I did ground my self by the touching the metal case with my fingers before taking out components or touching anything else within the pc

2) I did completely disconnect the power supply cable from the pc before opening it up and starting work.

3) I did put the ram stick into the slots properly with firm pressure until the clearly made a clicking sound and sort of locked them self into place while the 'latches' (or what you call them?) locked them self down on the ram sticks.

4) During troubleshooting and problem solving, I did try to take out the GPU in order to access and remove the motherboard battery, which I put aside for at least 10 minutes (to revert back to factory settings in the BIOS) before putting everything back into place again, which did not help and when booting the pc, it made the same odd long beep sound without going to BIOS or any startup and without signal in the monitor.

5) I did press and hold the outer case power buttong for more than 30 seconds at every retry of installing the ram, before removing them again.

Question:

1) Since all 4 out of 4 memory slots are being used, it should not really matter in which order I put the sticks in? Like starting with the second closest to the cpu or whatever?

2) Do any of you kind people out there have a good idea as to what I could try to do to make it work? Any ideas about what the problem here is?

Extra details:

I bought 2 different ram packages, from two different second hand sellers. Each package contained 2x16 GB, 32 GB per package, both at 3200mhz, both Corsair Vengeance LPX. If you look at the two packages (they both came in original packages), they look completely identical, with the same exact letters and numbers and same precise images and illustrations. But there might be some very small difference somewhere that I am not fully aware of, I can try to look more into that if any of you believe it is relevant. None the less, I did also pair them so that the 2 stick from the same package went together in the installation. So for example I put the first stick into a slot, then junped over/skipped the next slot in line and put the second stick from that same package into the next slot and then I installed the last 2 sticks from their own package them came from (just to be on the safe side).

Thank you in advance, if anyone is willing to give some advice here and I will let you know that I live in Northern Europe, just in case someone replies from a completely different timezone and wonders why it may take long time for me to respond, then maybe it is because I am sleeping at night while they are awake during the day...

What happens if you only use 2 sticks?
Hi,
I was just in the process of testing running only one stick. I have not tried 2 sticks yet.

I will tell you now what happens with 1 stick (one of the new ones with 16 gb)

The pc tried to boot 3 times in a row, where it booted and then shut down, but the third time it booted successfully and now it shows a BIOS screen:
Among other info, it tells me to press f1 to continue or Del to enter bios setup menu, so it seems successful now with 1 stick at least.

I will test with two sticks as soon as possible and respond back to your question soon.

Thanks for responding.

The manual that I found online says that it will accept 64 GB at 2666 MHz. You may need to turn off XMP so that it tries to boot at default speeds.

PREDATOR ORION 3000 USER'S MANUAL https://www.bhphotovideo.com/lit_files/627687.pdf
Thanks a lot and for link to the manual, that is great.

With this successful boot with one stick I registered the ram as 2133mhz for some reason, even though the stick is a 3200mhz, so perhaps it has already scaled it down automatically like you talk about?

Anyway some other research online shows some weird problems with Acer systems, where they have intentionally made it almost impossible to acces xmp configuration settings in BIOS:

"
Well, unfortunately, Acer does not want you to be able to configure the ram XMP setting.
I downloaded their bios corresponding to your machine, loaded it into a bios editor, the memory tab option is there, but hidden as other bios options.

You can check this Reddit thread, about keystrokes combination, to unlock the hidden menus.
If it does not work, you would need a modded bios, that unlock all the usual bios options, that Acer doesn't want you to access to."

hi again,
I am finally back with an answer for this question.

I have just successfully booted now with 2 sticks.
In the bios menu it shows 32gb ram but at the same 2133mhz and not the 2600mhz, which it should be able to support by default?

Also thanks to the manual that you linked to, I have put them in even more correctly now, since I now know what is DIMM1, 2, 3, and 4 and the right sequence to put them in with.

Anyways, guess I will try with 3 sticks soon also.
Still weird that it runs at that low 2133mhz and very irritating I bought a pc where access it denied to xmp settings, so I can never run ram at 3200mhz.
It is true that it says in the manual, it is only 2600mhz that is supported, I just read many places prior to purchase that it supports 3200mhz, it is so confusing.
I hope that the 3200mhz of the sticks them selves is not the thing causing trouble... hmmm...

2133 is the default speed for most DDR4. 3200 is an overclocked speed. To enable that speed you have to turn on XMP or set the speeds manually. Easy to do with diy motherboard BIOS but for OEM stuff it's hit or miss.

Thanks,
Yea was starting to understand that this whole setup was not really designed with much tinkering and upgrades in mind, for the owner... Would need a new motherboard it seems.

Now I tried to put in all 4 stick again, and the same problem arises, now nothing works, the same long beep sounds comes up and nothing happens on the screen.

I see in the manual that the only way to put 48 gb ram, would be to fill out all 4 slots, but with 2x16 + 2x8, So I can't test 3 of my 16gb sticks to see how that goes.

But I will test now the two last sticks I put in, I will put them in DIMM1 and 2 and have nothing in 3 and 4 and test those 2 compared to the 2 other 16 gb sticks that already have proven to work.
Then I will know if all the sticks actually work well on their own at all...

I can add that I now have tested both pairs of 16 gb sticks in DIMM1 and 2 on their own of a total of 32 gb, first one pair of 2x16 in slot 1 and 2, then the other pair in slot 1 and 2 on their own.

One package of the sticks seems clearly to work well enough, but when I tried the other 2 sticks on slot 1 and 2, the same error appeared that appeared when I put all 4 sticks in on the same time:
the long beep, no proper boot etc...

So it could seem like perhaps 1 package of the 2x16 gb ram may have some problems on their own... perhaps... At least there is a clue, this could be the problem...

I will test one of the 16 gb stiks one its own from the package that has caused problem.

I think perhaps I should close this thread now.

because i have tested the old 8gb ram sticks together with the 2 new 16 gb sticks to fill out all 4 memory slots for a total of 48 gb (2x16 pack + the old 2x8 pack) and it works great.

So it seems fairly clear to me at least, that the problem really lies with one faulty 2x16 gb package I bought second hand.

but thanks a lot to take the time and especially to find the manual for me, that on helped a lot.
