Computer doesn't boot, PLEASE HELP

[warriorunited]

Hi all I just created this account to ask for help...

- Asus H170 Pro Gaming
- i5 6600
- G.Skill Aegis 16GB (2x8GB) 2133mhz
- Corsair RMX 750
- Asus 1070 Strix Aura

The problem is... The PC doesn't boot up with both sticks of RAM at the same time, it only boots up with one.

I've already tried both sticks alone on every RAM slot and always boots up... But if use both stick, whatever their positions, it just doesn't boot up.

I tried updating the BIOS wich was on a very older version of that Mobo and still nothing.

Some clues on what might be? A faulty Mobo?

Best regards.

Hi

dont panic yet.


Have you checked all your cables? Is the 2 x 4 pin cable attached?

Try reseating your ram.

That LED - if it's on solid it shows a fault but the picture isn't clear enough to say what it is. It will be Boot Device (HDD or SSD, could be an incorrectly inserted cable) or DRAM LED (memory issue). I've checked the manual and the memory is in the correct slots so it's not a slot issue.

Double check what LED is staying on - it's telling you what fault it is.

Just tried to boot up the computer with only one stick of 8GB (16GB in total) and now it booted up.... How i fix this? lol. Do i have a second stick broken is just a BIOS configuration?

Well, switch it off again and put the 2nd stick back in - see what happens.

 

[Jetster]

Try the other by itsself

Its not a setting in the bios

 

[warriorunited]

Ok, so the Motherboard only boots up with ONE stick of RAM. I tried running with only one , testing both and it booted. If i put both sticks, it doesn't boot up. Should i update BIOS?

 

[warriorunited]

Just done updating the BIOS (was very very very outdated....) and still nothing. The computer only boots up with one stick of RAM.

Tried the RAMS on different slots, and no result either. Just don't know what to do anymore... Is there anything else to be done?

 

[the54thvoid]

BIOS should be fine.

On my motherboard, I cannot get the RAM working unless I use 2 x 8GB in two specific slots. I used to use 4 x 4GB but after a water cooling incident I believe i damaged a RAM slot. I think i caused my damage because when i put my CPU back in, I bent a socket pin. I actually bent two but i managed to reset one of them but the other sits funny. I think my clumsy hands caught a pin and that is why my memory slot doesn't work. But, I use 2 sticks of RAM now and don't use the broken slot.

I don't know if anyone else will agree if it's worth taking out your CPU and checking your 1151 pins are intact.....

 

[warriorunited]

No man, it's not CPU problem, it's the Motherboard, for sure! The computer only boots up with one stick of RAM, and i've tried both sticks at once on all RAM slots and it boots. It just doesn't boot with two sticks at the time.

 

[the54thvoid]

Ah, ok - so every DIMM slot works (A1, B1, A2, B2) if you just use one stick of memory? I guess you tried that with both sticks? That would be 8 tests of slots and memory to check. Have you really checked that out?

If so, I'm out. I still think a bent socket pin can cause those sorts of weird issues but you know best and removing CPU's once seated and thermal pasted is a pain in the ass. For record, a bent socket pin looks like...

Yes, i've tried that, and i am right now instaling Windows, because everything is running fine, i just can't use two RAM at the same time what the hell...

return the board. or check ram compatibility listings for your board

 

[warriorunited]

return the board.

I'm going to do that, it's the only thing possible, a faulty mobo. I just tried another kit of RAM from a friend, and same thing happens...

Before you return the board, check the pins. It they are bent, you will not be able to return. This goes back to what @the54thvoid said.

If you can use each piece of RAM in every slot, then it is either CPU (the memory controller is in the CPU, not the motherboard) or the CPU pins on the motherboard.

Its not a windows problem so there is no need to reinstall it every time.

If the CPU pins and socket check out ok, plug a memstick into slots 1 and 3 (not 2 and 4, yet), do not power up yet until you follow the procedure to reset the CMOS for that board. If you can get into the BIOS with both sticks, this is good. Do a complete memtest.

If not, use one stick so you can boot and get access to the BIOS. Scan thru the BIOS at all the memory settings that everything is on AUTO, and nothing has been disabled accidental or not. Do a complete memtest with each stick. Try to find out what the BIOS is reading the timings of each stick.

While in the BIOS also take notes of all the CPU settings.


if all else fails start to take pics(use phone, etc.) of CPU and memory screens and post them for us.

^^^This.

Easy with the responses buddy, the only reason they are recommending something that seems impossible to you is because the majority of us have dont this more tha once. On a side note before wasting your time installing windows which is a really bad idea to do right now because you have hardware issues that can corrupt the OS resulting in you posting yet another thread about random BSODs I would run the ram sticks (individually obviously) using memtest to rule out issues with the sticks.

To lay it out a bit technically, (I know some people refuse help unless they are certain the people they are talking too understand it.)

When you first boot a machine a specific portion of memory is reserved for BIOS and STRAP code. This is usually only a few kilobytes. (the POST test code for memory comm is usually called BASE64k in case you were wondering)

When you change the amount of memory and amount of sticks the address spaces it is kept in change. Meaning it could be attempting a R/W operation on a segment of nand that is failing when both sticks are being mapped at the same time. Furthermore this explains why both sticks may work when by themselves. Which only means when more memory is consumed (by the OS or programs) the machine will run into issues when attempting to access that memory address space.

ya follow.

Now lets look at the other alternative. CPU and motherboard. Both could be causing the problem. Why?

The IMC (memory controller) on todays boards (since like 5+ years ago?) house this on the CPU. It is not part of the "Core" in a conventional sense and could exhibit problems even though the "Processor seems to be working fine because it boots with one stick of ram."

The next option is the motherboard itself and the communication between the slots and CPU socket. As well as the BIOS doing the initial provisioning. Chipset issues and socket problems (bent pins) are a big cause of memory related issues. that show up as

failing ram
dead slots
slots that only show ram once in awhile
ram shows in bios but OS says x.xGB is hardware reserved.

most of these issues again assuming they are mobo related specifically are caused by

chipset-configuration settings regarding voltage timings or otherwise.

socket-bent pins or damaged pins or corroded pins or pins.

PCB communication- Issues with traces, warped boards caused by cooler mounting tension, board flex, broken caps/transistors damaged slots (bent pins corrosion etc)

but you know im just guessing your probably right. you and your friends ram kits are just bad at the same time. #runit #yolo.

 

[DeathtoGnomes]

yea forgot how touchy windows is when you have hardware issues.

 

[warriorunited]

Sorry guys, i dont want to be rude or seem like it on My answerd, i was just under stress because of that situation... Sorry again.

Answering some of your questions:

The LED that stays on when i power up it's the DRAM LED, he does pass the CPU LED without trouble.

When i got from work, um going to try checking a few other things that DeathtoGnomes said before going back to the store.

Thank you all for your help until now.

 

[FR@NK]

I would install one stick and get into the bios and set all the settings to manual; like the FSB clock, the memory strap, memory timings, and maybe bump up the CPU and DIMM voltages.

Also, how long are you waiting for the system to start up when you power on with two sticks? I've seen systems that take afew mins to post the first time when you change memory settings. After that first time it will start up fast until you change another setting.

 

[warriorunited]

Okay, this is getting weird lol... I tried something i haven't tried yesterday wich was to connect both sticks bad connected, i mean i connected them on A1-A2 and guess what... It did boot up... If i connect the correct way A2-B2 it doesn't boot, A1-B1, B1-B2 does not either. What the hell...

 

[Jetster]

Some ram is temperamental on some boards. Just switch

 

[warriorunited]

I've tried the rams on another computer (VIII Ranger, I5 6660k) and it's happening the same as My computer. I guess i can finally say it's faulty ram lol

Your using 8Gb likely double sided double density ram which most integrated memory controlers treat different from single sided in that it can't be ran as quick due to timing etc, on Amd boards I could describe further but I'm I5 iliterate I'm affraid.
Try much looser timings ,look up your mobo and find out its max speeds allowable for DS/DD ram, then look up your memory and check you have the timings set right if so loosen the timings a bit more and retry.
I say this cos I've often had issues with my mobo and different memory, inc it appearing the same as your fault does.
Ie its memory timing profiles are not liked by your mother board , what speed are you running it at too ,1333 would be best for initial testing at jedec set timings ,then if it works slowly clock it up to the best speed it can do.


Oh and this suggestion or one like it should have been near the top before hardware swaps , shit my pc took me setting the timings with 1 Mushkin stick in as 2 didn't work as yours are until its base timings were right and guess what it stalled on the ram led on post too.
