For example, what type of VRM's (and how do we tell the good quality ones?), what type of chokes (again, how do we tell?) how many VRM/phases should we look for minimum? And finally, what company consistantly produces the best quality boards? I've seen you talk about Asus problems and bad ASRock VRM's, so who *DO* you recommend ?
Thanks in advance!
Gigabyte and Asus have my vote for best VRM's.
I've never had a Gigabyte board, but Asus boards have always given me great VRM's and usually have some nice bios options to tweak them. If you start to overload them they will throttle the CPU to lessen the load on the VRM's, and if you really overload them too much they will shut the board completely down to prevent VRM failure and component damage. I would NEVER get an MSI board though because that brand has been known for VRM failure even with the higher end boards. Don't get me wrong, there are good boards from MSI.. but most of them are just ick, and don't offer any VRM protection should you overload them to a point of no return.
I'd say if you want to try to go for a max 24/7 OC then I'd get no less than a 8+2 phase VRM setup. Anything after 12+2 phase is overkill IMO unless you're going for a LN2 high voltage bench/etc. Also, the more phases you have the smaller each one tends to get so there really isn't too much of a benefit of having like a 16+2 phase or something ridiculous.
Just so you know, VRM's are located to the LEFT of the CPU socket. Most of the time on good quality boards you will see a nice heatsink there and sometimes going above the CPU socket as well. Edited by iinversion - 4/1/12 at 11:02pm
