I'm playing around with this dual C621 3647 socket motherboard. I brought this on a Chinese second-hand market app. It's said to be retired from Amazon AWS data center. The BIOS indicated it's manufactured by FOXXCON. No other documentation or user manual can be found about this motherboard. Cheap, but no support no warranty nothing.
I put in two ES CPUs with the code QL2K. At first the CPUs are working fine as the above shows. All LEDs on the board are green.
It's said that these CPUs' multiplier are unlocked. I tried unlocking the hidden menu in the BIOS using AMIBCP and then tweaking the CPU with Intel XTU and ThrottleStop. But I haven't been successfully in overclocking it. There are Power Limit and Current Limit which I don't know how to unlock.
Then after once shutdown, the board can't boot. There are 8 LEDs near the Altera MAX 10 fpga chip and the 5th (from left to right, or 4th from right to left) LED goes red just after 1 to 3 seconds right after boot.
I don't know what config actually caused the issue. I tried remove the second CPU, CPU1 and only keep the CPU0 then it works. I tried swap CPU0 and CPU1 and it works. This only happens when CPU0 and CPU1 are both installed, it appears the second socket becomes bad...
I have tried remove the CMOS battery. I also tried clean the CMOS using ipmitool ( ipmitool -U root -P changeme -H SP-IP chassis bootdev disk clear-cmos=yes ). I also tried flash the BIOS and BMC chips using flashrom and ch341a programmer to it's original backup. (https://paste.c-net.org/HarrietConcept) But nothing works...
What to do?
