Solved Cannot Boot to Bios - No Video or Boot. No Mobo speaker.

February 4, 2017 at 16:20:30
Specs: Windows 64, DDR4 - Varying mhz
Weirdest issue I've had. I'm sure I'm overlooking some trivial thing. It's a new setup for my brother. The setup is as follows:
[list] Mobo: ASRock Z270 KILLER SLI/AC LGA 1151. [/list]
[list] CPU: i5-7500 Kaby Lake Quad Core 3.4 1151. [/list]
[list] HDD: WD Blue 1TB. [/list]
[list] ]PSU: EVGA SuperNOVA 650 G2. [/list]

The issue is the RAM. I tried 2x8GB Ballistix 3000mhz, after having been told that it will downclock itself. This is where the strangeness began; every slot on the MOBO works fine with this RAM, with just one stick inserted. However, no matter which order I put them in, even incorrect ones (1221, etc.), it will not work with two sticks. Both sticks function fine on their own. I decide, fine, 3000mhz isn't listed specifically on the mobo specs, maybe it's having an issue downclocking. That RAM was Ballistix Tactical 8GB DDR4 3000. So, I swapped it out, and tried Ballistix Sport 2x8GB 2400mhz, which looks like it matches the CPU and Mobo requirements. Neither stick will work, no matter which slot or slots they're in, either on their own or together. It simply will not boot to BIOS. All I get are fans, lights, and nothing else. Keyboard doesn't light up, monitor gets no signal. I'm completely at a loss here. I've reset CMOS more times than I can count. I tried going into UEFI under the good RAM (which I no longer have; exchanged it for the new RAM) and playing with the settings to manually set the mhz, but it didn't have any effect, except making me reset CMOS and refum I missing something re: compatibility, or have somehow managed to screw up RAM purchases twice in a row? Thanks for all your help, guys!

✔ Best Answer
The memory you are using is not listed in the Asrock Memory list:
http://www.asrock.com/mb/Intel/Z270...

Even on the Crucial website, It is listed as not compatible with your motherboard:

(run the "Will it work on my system" check

If you don't have a speaker for the board, get one & install it. It's very important to be able to use beep codes for troubleshooting. Do you know which BIOS version you have? Update 1.10 improves DRAM compatibility. There are also two Beta BIOS - 1.30 & P1.31A. Unfortunately, it appears you're going to have to get different RAM to be able to do anything. Are you still in the bench-testing phase or did you already install the hardware in the case? Or did you skip the bench-test step altogether? Bad move if you skipped it.

Riider: I'm not sure. https://www.newegg.com/Product/Prod... is the model I bought. It was purchased several weeks ago, so I doubt it's the 1.31A.

I ordered a set from the approved list that sluc kindly provided. I never stay abreast of tech updates as much as I should. Always thought that it was alright if it was within spec for the CPU and Mobo.

If the new sticks work fine, I'll let you guys know. Same-day delivery (thanks, Amazon!). If I still have the same problem, I'll follow up with you, too.

You guys rock!

I just edited response #2. A board will NEVER ship with a Beta BIOS. If it shipped with the original BIOS 1.0, updated BIOS 1.10 may have fixed your RAM issues. Also, without the speaker, you don't know if you simply didn't install the RAM properly. If the board was already installed in the case, it will flex slightly while pushing down on the RAM & this can sometimes prevent it from seating fully. If the RAM is installed during bench-testing, the board has full support underneath & the RAM can be pushed down firmly & evenly.

I installed the board with stands myself, it's definitely seated fully. I wish I still had a mobo speaker to listen for beeps, but I'm fairly confident that's what it is. The part that mainly confused me was that the original (3000 mhz) set worked, but only with 1 stick at a time. Since I can't boot to BIOS as it is, I doubt I can update to beta. If I could, I would definitely try that. If you're curious, when the new RAM shows up, and it works, I'll try updating the BIOS and using the old ram with the beta installed, and let you know if it works.

If you boot into BIOS select the XMP profile for the RAM if that option is available. This sets the memory to all optimal settings all for you and you can take advantage of its best available speed. It also sets necessary voltage and latency which sometimes prevent some memory from working or working optimally. It also may allow the use of the second stick if you can only get into BIOS with one installed. If the XMP profile is not an option on the mobo or RAM then read all specs from the sticker on the memory an set it all yourself manually.

You have to be a little bit crazy to keep you from going insane.

Bought a 16GB set from the approved list, works great. That's the last time I trust someone at Micro Center to tell me what's compatible with what! Thanks for all your help, guys, really appreciate it. Tried fiddling with the settings to get the old RAM to work, just out of curiosity, but all I wound up getting for my trouble was having to reset CMOS a few times. Thanks again!

I bought approved RAM for this board that was listed right on ASRocks website and had all kinds of issues. Just updated bios to 1.3, which seems to have fixed these issues. It may have been your bios more than anything... Just saying.

Swapping the RAM out worked fine without touching the BIOS for me. I'm glad you got yours working, too, though! I think the poster above mentioned that 1.3 fixed other compatibility issues. Seems like this mobo just doesn't like RAM!

Hello I bought this ram model
Crosair CMK8GX4M2B3000C15, and it's not in the list it's difficult to buy another ram so what is the solution?
