8GB 2400Mhz not working on Z77 + i5 3570K

post #1 of 3
Thread Starter 
A week ago, I sold my only set of RAM (8GB 1333Mhz) to a friend. Just today I picked up a new kit of 8GB 2400Mhz RAM (from Team). Installed it, and I can't even get to the BIOS. My system won't boot up, at all. I get no video signal (currently using the i5's iGPU) at all and Dr. Debug gives me either D6 or D7, which is "No console output device found" and "No console input device found" respectively, which strangely don't seem to be related to the RAM... but as far as I/O is concerned, neither my keyboard or mouse light up and like I said, I get video output from my DVI port. This only started after putting in the new 2400Mhz kit, and I have no other RAM to test out right now.

Motherboard is an ASRock Z77 Extreme4, CPU is an i5 3570K, and the RAM is a 1.65v kit (as opposed to the 1.5v kit I had before). I have cleared CMOS multiple times and it didn't help anything. I have also tried installed just a single stick (tried them both individually) in each of the 4 available DIMM slots. Have tried the pair together in both the 1st +3rd slots and the 2nd + 4th slots. Motherboard is rated to handle 2800+ Mhz RAM, and while the exact model number of this RAM is not on the official supported RAM list, there is a 8GB 2600Mhz Team kit that IS on the list, and if that RAM works I don't see why mind wouldn't. I thought any 240 pin RAM that was within the MB's rated speed would work...

I was anticipating the possibility that I wouldn't be able to boot Windows if my CPU or MB couldn't handle 2400Mhz, but why can't I even get to the BIOS? Any tips on anything else to try? redface.gif

You may want to try updating the BIOS to the latest version. It's rare, but sometimes certain types of RAM are incompatible with certain motherboards.

The RAM itself could also be faulty. See if you can find someone who can test it on another board for you.

I don't think I can update the BIOS if I can't even get into the BIOS menu thumb.gif

I'll see if I can test on a friends PC
