Well... I read around of many people made the step to the new BIOS without issues...
Just wondering if there is a specific parameter to look at to improve stability. For example, I read on Reddit about people reaching stable 1900 IF lowering SOC voltage, which is something against theory.
I'm not so addicted with hardware I can't run my pc at CAS16 for a while.

I've tried raising VRAM to 1.45 but still get beeps on boot... best I can set now is CAS 15 but with GearDownMode enabled it's 16 (with GDM off it won't post).
Any advice for me?

If the PSU is on (not in standby) You should be seeing 12VDC across the pins on all 4 pairs of the 8 pin connector (sometimes called ATX12V 4+4, sometimes called EPS 8pin)

Doing that is tricky - you have to attach the main ATX power connector to the motherboard (or jumper it) to get the PSU to power up, and them carefully measure the 4+4 or 8pin connector. Be aware of which pins are +12VDC and which pins are ground. You can use the following webpage as a guide: https://www.moddiy.com/pages/Power-S...d-Pinouts.html

On some modular power supplies, it's possible to plug the modular cables into the wrong jacks on the power supply, so just be aware of that possibility.

Otherwise, if the PSU was properly powered on (not in standby) and you're only seeing 6.5VDC on the EPS connectors, you should consider replacing the PSU or at least contacting the manufacturer for support.

New CH8W with CPU Power Issue

I'm not an electrical engineer, but I feel like someone should be paying me like one...

Is this normal?

THOR 1200 P PSU should work amirite?
No, it's not normal. First, just for the sake of testing, I'd only connect the 8pin connector. (The additional 4pin isn't really needed unless your going for extreme overclocking or your PSU cables use thin wires. The motherboard should boot fine with only the 8pin connected (in addition to the normal ATX connector, of course.)

If you get the same issue, try to swap cables and/or connections to the PSU. (If it's a modular PSU, try a different cable and different PSU connector. If it's not modular, then just a different cable.) Again, stick with only the 8pin connector.

If you still get the same issue, I'd check that the cables/connectors with a multi-meter to ensure they are providing 12VDC on all 4 pairs. If the cables/PSU connectors are all good based on a multi-meter test, but the motherboard still acts as if it's not getting power on the connection, I'd exchange the motherboard for a new one.

Definitely check to see if something's not making a good thermal connection. I've got a C8F and the fan is inaudible at 60C and it never strays from that temperature. There are others here who usually say something similar. If yours is getting to 75 then I think something isn't making contact.
