But the Mpower boards are still MSI boards on z77. All MSI Z77 boards lack offset voltage control, at best they only have Vdroop voltage control only.
Why would you buy an mpower when you could get a gigabyte, high end asus/asrock instead, and for the budget range I don't see anything beating out Biostar. If not biostar maybe asrock pro3, Asus LX (offset only). Biostar is the king of budget, the way I see it, asrock isn't bad at lower level, while Gigabyte, Asus, are the king of higher end. You don't buy a Toyota Spyder, and you don't buy a Porsche SUV.
I happen to have an msi g41, i'll be testing it this week though. I know but it's a build for someone else, im just tuning some near stock voltage or so oc for value. it was $19... I mean when I bought it the UD5H was $79 - and one way to look at it, it's basically $60 for ~500 mhz or so, (4.5ghz vs 5ghz on the ud5h, which is being a bit generous, but then there's memory and bclk overclocks to factor in im sure). I think for value, like actual useable performance, a $19 msi g41 is comparable to a $79 ud5h.
But for someone who actually enjoys overclocking, even just the tiniest bit, and being generous about the impact of overclock and the difference in overclocks, then the ud5h at $79 is a way better deal, hence why i got it for myself.
if that makes sense.
rhosigma it sounds like you are just caught up in marketing lingo lol. Im pretty sure gigabyte doesnt give a rats ass to go to the military (what military? who made this designation? The military of taiwan? Oooo that means something to me, they don't even have nuclear weapons bro) and get some kind of stamp.
Kind of like the whole PSU bronze/silver/etc thing is a useless designation too that's just jumping silly hoops that's no real reflection of the PSUs actual performance or quality, and can be easily faked.
A lot of the reviews you posted are pretty questionable too. besides Sin's overviews, i almost never see good motherboard reviews. I mean it's a well known fact that gigabyte and asus, especially, as well as other motherboard companies, fudge stuff like setting the bclk at stock to 100.01 or slightly overclocking the system at stock on load and giving artificial voltage readings (so you think oh wow this board does the same oc with less voltage!) and ram overclocking, then these reviewers 'bench' the boards and say one board is better than another based on some bench score. A CPU at 4ghz is a cpu at 4ghz is a cpu at 4ghz, i mean the cache has a bigger impact than the motherboard on performance.
Motherboard is kinda like a power supply, you just want one that does the job. But unlike a psu i mean you can really push a motherboard to its limits with overclocking even just air 24/7, so having a decent motherboard can make a difference, or rather, hold you back less.
Does anyone know if the biostar have digital power design? I dont know if there is a real advantage to this, but i have heard analog can create coil whine at certain frequencies? I
The chokes on the TZ77A look exactly like the chokes that I had on my Biostar A770E3, a $30 motherboard I bought 3 years ago for my athlon ii x3 build. Great board, for a 3+1 phase, anything less than burning out in a fire and taking out my entire system with it, would be reason to give the board 5 stars for the overclocks and volts I pushed on it (got 3.8ghz on c2 phenom, basically the max a c2 has ever gotten on ambient so great board), but it would get coil whine when the mosfets reached 90*C or above (id use duster held upside down to spot cool them to stop the whine during benching).
The TZ77A has more phases, probably at least some better stuff in there, has a heatsink (a proper one, not some sawed am2 heatsink like I used), and is for sb/ib which use less power than a phenom x4. I think for a sub-$100 or whatever board it's fine. I would imagine the quality is on par with other boards it's price level.
And coil whine has nothing to do with analogue or digital PWM. It mostly has to do with the choke quality, and a little bit about how the VRM manages itself, the drivers, phase count, et cetera (ie how well the load is managed between phases). It tends to happen when chokes get hot, the coil in them starts degrading in performance and then starts shaking too much. It makes more sense if you look at a picture of an old coil choke, which is just a ring, most modern chokes are inductors, a box but the ring is inside it). You see them in PSUs sometimes, if you look in there:
By the way, my MSI-G41 has nikos mosfets. They look 'newer', different, than the NIKOS that were on my Biostar A770E3, but they still lack low rds on. I guess I'm okay with Nikos on boards under $30 :XEdited by Belial - 1/31/13 at 10:50pm
