Hey TH. Turning to the gurus for help

I tried to install some new RAM on my rig today, it was working before I shut down the system to install it. I got the Patriot Viper DDR3 8GB (2*4) 1866mhz.

My motherboard, intel desktop board dh55tc can only support up to 1333 mhz RAM, however I was under the impression it would automatically detect and cap the speed, due to a forum post I read.

Upon removing 2 1GB sticks from my channel B slots, and replacing it with the 2 4GB cards, on restart my CPU, GPU fans turn on, my HDD light is on, but I don't get a display, out of my integrated graphics or any port in the GPU.

I did some reading and tried resetting the CMOS, restarting with only 1 ram card installed, putting in the old ram, and now whatever I try I am not getting any display on my monitor, which works because I am creating this thread on it right now.

I removed all RAM and my motherboard beeped at me, so it's not the motherboard that's dead.

PLZ HELP. Computer was built by previous owner, but have had no issues until this point. Without completely disassembling the entire CPU and playing an endless game of trial and error on my friday night, are there any hotfixes that you /g/reat people might have for me? Advice?

As the title states, I have completed the sticky checklist without any results. The only thing I'm still doing now is checking the user manual, but I have put off testing individual RAM bays and cards as my rig was on and working perfectly before shutting down to install the new RAM.

Thanks in advance.

Please refer to your manual if you don't know how to access the BIOS and change settings. The modules should normally use the SPD settings. What modules are installed and what are the settings in the BIOS? If it boots, you can use CPU-Z Memory and SPD tabs; note that CPU-Z reports the real frequency which is half of what you may expect, e.g., 667 MHz actually is 1333 MHz (DDR).

1. Are you sure the modules are fully inserted? Try with a single module.
2. I doubt the new RAM is compatible with that old system. If they are manufactured with only 8 high density chips, then they won't work. G.Skill F3-10666CL9D-8GBNT will work because it's manufactured with 16 low-density chips.

Thank you for the quick response GhislainG

I figured I screwed up with the RAM, but do you know what would now be preventing a video signal when I have the old RAM installed, a build that has worked for years?

I get a boot, just nothing coming out of my GPU or integrated graphix, any port.

I have tried with a single module, and I'm pretty sure they are fully inserted, they click into place.

I will continue to test individual modules and bays, but should I be resetting CMOS each time? I just can't deduce what the problem is as I can't even get into BIOS at this point, but the RAM bays speed should be automatically set for the old RAM shouldn't it?

How do you know that it boots if you can't display anything at POST? The new modules won't work, but the old modules should. It always is possible the motherboard was damaged when inserting the new modules, but I suggest you test with minimal components installed (motherboard, CPU and a single memory module) with the monitor connected directly to the motherboard. Nothing else should be connected (HDD, SSD, keyboard, mouse, GPU, etc.) If that doesn't work, then remove the motherboard from the case and perform the same test again.

The CPU fan, the GPU fan and the HDD light all come on, I get a single beep when I push power, like always, but I just don't get any display. No accessories are connected but i will try removing the GPU and the HDD next

UPDATE: after trial and error, removing the GPU and starting with one module, I do have display, and am able to enter BIOS. What are my next steps before putting the rest of the RAM back in, I don't want to be back to sq 1

Bear with me, I inherited the rig. The GPU and RAM worked fine together before, so I had no idea to remove the GPU, again forgive me, I'm pretty vanilla at this.

If you're still here, I am unable to boot with more than one stick of RAM installed
I have updated the BIOS and am about to run Memtest, do I have to set the voltage and the speed of each ram bay?
Or should I try loading optimized defaults

Thanks for trying to help. I installed the RAM module by module and it booted. Then had trouble with my GPU but I just reset it and changed my video boot settings to auto and then on the next boot it ported to my GPU instead of my integrated graphics.
Not sure what was amiss, but my rig is back to working condition, and I think I will be upgrading the motherboard before I attempt to make any further modifications.
