Asus Maximus V Formula - Questions and Concerns

post #1 of 3
Thread Starter 
So I decided to upgrade this week to the MVF but I'm still using my Sandy i5 2500k CPU for now. I've been using an Asrock P67 Extreme6 (B3) and it has served me well. It was still working fine when I made the switch yesterday. My initial thoughts are that the Asus board looks wonderfully built, however I'm not very impressed so far with the stability of this board and I fully realize that there's dozens of settings to tweak on this board but even with most settings to auto and just manually adjusting a few like voltage, LLC, etc, this board seem to require a good bit more voltage to keep my CPU stable than the Asrock did. The Asrock would run this CPU at 4.2Ghz at only 1.25v, prime stable for 12-24h hours, this Asus MVF seems to need closer to 1.3v for the same stability. LLC is adjusted to the same level as it was before on my Asrock which in this case is Extreme setting, it was numbered on the Asrock 1-5, 1 being the highest and I had it set at 2 so Extreme setting is the Asus equivalent.

I also changed heatsinks during this changeover, going from a Cooler Master 212 to a Thermalright Venomous-X, temps dropped by about 8c under load even with the added voltage from the Asus to maintain stability, but why does the Asus require so much more voltage to maintain the same stability even with cooler temps?

Also, playing around with the CPU Level Up option, does anyone know why when I choose the CPU Level Up option, it always tries to raise the Bclk to 103 instead of just leaving it at 100? It gives me three Level Up OC speeds, each of them it raises the Bclk to 103. Is 103 more stable on this board or something? These are pre-programmed settings by Asus so it seems they wouldn't choose it if it weren't best. None of them have been stable everytime it sets it. I can get into Windows but it crashes under Prime. I may need to raise the voltage for stability but I know that raising ther Bclk can also cause instability so I was wondering why Asus is doing it. I know most people frown on auto overclocking and I generally don't use it either, but after so many reviews that this feature works wonderfully on this board by every review I've read, why is mine seemingly not Prime stable?

Extreme is the equivalent to ASRock's setting of '1' because Extreme is the highest option. Or, is this wrong? That's why you have to set the voltage higher in the BIOS. There's more vDroop. This doesn't mean that your actual core voltage in Windows is higher.

If Level Up is setting the BCLK to 103, then I would stop using it because it sounds like some kind of automatic overclocking for people who don't want to figure out how to overclock.

Extreme is the highest setting for LLC, I should have said I was using the Ultra High setting which is the second highest meaning it gives 75%. Asrock has a setting of 1-5, 1 being the highest LLC which is practically 100% so Ultra High is the same as level 2 for the Asrock. The vdroop is the same on both boards at equivalent settings, the problem is that the Asus simply requires more core voltage to get the same stability even with a lower temp.

Level Up probably is a quick and easy way to OC for people not familar with OC'ing. I don't use auto-overclock options and I know how to overclock but since Level Up is touted as a feature for the ROG boards, I thought I would see how well it works given that all of the reviews for this board are good and they all say this feature works well. I'm just not seeing that and was curious if everyone else is seeing the same. I was also curious why it was raising Bclk since most people don't do that unless they're extreme overclocking for records. I thought it might have been a quirck with this board that it prefers a slight bump in Bclk and was wondering if anyone had seen this or knew the answer.

That being said, the reviews says its great a board, I've certainly going to keep exploring the OC options in the UEFI which it has in abundance but I can't help but feel a little dissapointed that a flagship board like this isn't performing any better, if not worse than an Asrock board that costs half as much.
