I need someone to share their experience with MSI's Tomahawk and Mortar experience (I heard it's about the same quality) on the boot time and overclocking experience. I've read of long boot times on reddit and of low overclocking capability (or no State overclock). Would like to verify those facts.
Thanks for the help
I have the Mortar and I can confirm it's not featured with P-State overclocking as of v1.7 BIOS.
I'm running an 8-core (R7-1700) and I think it's fair enough to say mine over-clocks as well as any other b350 motherboard. Which is to say: you're pushing it really hard at 3.8G. While you might get 4.0G you'll not have any kind of stability even for a short stress run. It should (might?) hold for browsing and light, single threaded, game play though. A 6 or 4 core might fair better.
This is common throughout the B350 platform: all the mfr's have super-skimped on VRM section and, especially, MosFET cooling. It will hold stable even if I didn't but at 3.825G I have to put a fan on the MosFET's during encodes and stress testing or the temp blooms above 100C. That's very common on these boards, all of them.
One really nice thing is the Mortar has 4 fan headers so I put a dedicated VRM fan on one header and set it's profile to only turn on if CPU temp is above 65C with a 5 Second delay. So it only turns on if I'm really stressing the system hard meaning it's totally quiet otherwise.
Otherwise: I can only compare the Mortar to an AB350M Gaming 3 since I have one of them too. They both overclock about the same but the Mortar has, hands down, the superior BIOS. Better features and, with LLC, better voltage control so it's easier to get more stable overclock that's gentle on the CPU while idle. It's also seen more frequent updates and quicker attention. Just all around better.
Also, the G3 uses 'offset' Vcore adjustment ONLY which seems to screw up the ability to gage Vdroop in operation. So no utility can provide an accurate Vcore voltage while stress testing (I had to probe at the processor socket). Not good for tweaking a good overclock.
