Attempted adding more RAM but the DRAM indicator lights up and the system fails to boot.
System Setup: Processor i5-4690k, Graphics card MSI GTX 970, Motherboard Asus Z97-a, Power Supply EVGA 650. I wanted to upgrade my RAM. Initially had 2x4GB of G.skill Ripjaws and ordered another 2x8GB Patriot Viper. While mixing RAM types isn't typical, these options were cheaper and the new set fit perfectly with the existing configuration on the Mobo's QVL. I decided to test compatibility first, opting for the new sticks since they matched the specs. After some troubleshooting—clearing CMOS, checking voltage, using MemOK, trying all combinations, reseating CPU—I still faced issues: the PC would power on but not boot, DRAM LED lit even with old RAM. No visible damage or shorts found, but no solution emerged. I’m unsure what else to try and can’t flash BIOS without a post. Any advice would be greatly appreciated.
Yes you can actually, theres a socketed bios chip near the cmos battery but it may be covered with a warranty sticker You can reprogram using a 4$ usb bios programmer like ch341a, also might aswell upgrade the bios to z97 deluxe for better oc capabilities, also no more worries of bricking cause that is straight up impossible with a bios programmer that will reprogram your bios ic If bios flash doesnt work try dunking the cpu socket and ram slots with 99% IPA and clean the cpu and ram pads also with said IPA
Thank you for the idea. I've placed the order for the programmer, hoping it meets her requirements.
I placed an order for a CH341a programmer from Amazon. It’s worth mentioning that the available units on Amazon only provide 5V output, with some including a 1.8V adapter. My device required 3.3V, which wasn’t suitable for either option. On Aliexpress I found configurable CH341a v1.6 programmers, but shipping would have been too slow for me, and without soldering skills, I opted to use the standard 5V setup—everything functioned correctly.
I strongly suggest either adjusting the voltage or buying a programmable solution. Regarding removing and programming the BIOS chip, the video explains the method well; my process added a few extra steps. Luckily, my chip had a socket, so I avoided soldering and just had to be careful not to damage the IC pins during removal. The video includes links to drivers and software used for reading/writing the chip.
Before proceeding, confirm your chip model in the software’s documentation. Initially, I doubted support, but checking the datasheet on datasheet4u.com showed a compatible version existed. If ASProgrammer doesn’t cover it, consider NeoProgrammer (which supported one model) or explore pre-programmed BIOS chips on eBay—riskier but potentially effective.
Next, obtain your original BIOS file from the motherboard manufacturer’s site. You’ll need a .bin file to flash the chip. Unfortunately, ASUS only offers .cap files. There are alternative methods, but the approach in this video is the best path I found.
After reprogramming with the new firmware, double-check that read/write operations work properly. Once done, reinstall the chip on your motherboard and expect your BIOS settings to reset—so you may need to tweak them. This should help others facing similar issues, even if a professional repair saved you from a costly mistake. Thanks for the advice!
