Does anyone know the location of the onboard CMOS battery for STRIX Z690-I GAMING WIFI motherboard.
The reason I'm asking is the system worked fine on the bench with Intel Pentium G7400 Gold CPU with the included OEM Intel Cooler, RTX A2000 12GB card in PCIe X16 slot. Everything worked fine, I loaded Windows 11 Pro, and all drivers, updated BIOS.
OK,.. after updating system I pulled the Pentium chip and installed Intel Core i7-12700K CPU, and installed motherboard in LIAN LI A4-H20-X4 chassis, than custom water cooling single loop on CPU.
After completing the build in chassis, leak-testing, filling loop the system will not post, I have no DP out from graphics card, thus no monitor. The fans all spin-up, and pump starts, all DRGB lighting,.. but no display on monitor.
The GPU is mounted on the back side of chassis with a 4.0 riser cable.
Now is whare things get frustrating,.. I figured the riser cable could be the issue, so I re-set both motherboard, GPU connections and no luck.
Than I replaced riser cable with known working right angle 4.0 riser cable,.. just coming out the front with card laying on bench as all I wanted was to see if cable was faulty, but still the same issue no display.
Than decided to go with IGPU, pulled riser cable and tried onboard graphics both type-C ports and HDMI ports and no display.
I have powered off, pulled power cord, pushed clear CMOS button on rear IO several times and no display, no post with IGPU,.. which should default to on-board graphics when no card is installed as BIOS setting was in AUTO when I tested system on bench.
So I decided perhaps pulling CMOS battery, and pushing clear CMOS might solve issue. As it seems swapping CPU to i7-12700K must be the issue, as system was fine on bench before swapping CPU.
I have not started system after swapping CPU, I just pulled Pentium chip installed i7-12700K and built system in chassis.
Any thoughts, advice before I start tearing apart this system looking for CMOS battery,.. I know it's not under M.2 drives, or on back-side of board. I'm thinking the battery is located under rear IO shroud which means I will need to drain system, and pull CPU block to remove IO shroud.
Thanks in advance for any advice,.. hopefully someone has a fix for this issue that does not require pulling CPU block,.. 😛
