Can you elaborate on this? When you're talking 4 phases, do you mean the connectors that powers the CPU? I'm trying to get a 4GHz OC myself, and nobody told me of this. Is it something for me to worry about?


Edit:

Just read the reply with Chew's quotes in it. Just looked up my mobo's spec's to and it says "8+2 Phase Power Design" so I guess that means I'm okay?

Power Phases regulate the voltages and other stuff going to your CPU.

4+1 stands for, 4 for the CPU, and 1 For the memory.

If you have more phases, each phase will have to do less to out put the same amount of power.

ex. you have a 100w cpu load, and you have a 4 phase design on the CPU. Each phase would have to regulate 25w.

If you had 8 phases, each phase would have to regulate only 12.5w.

4 Phase designs are not known to hold up well under high overclocks, but MSI doesn't see it that way, and continues to use ony 4 phases on even their high end boards (890FXA-GD70). If you don't overclock too hard, I would not worry about having a 4 phase board, and any processor will run fine at stock on a 4 phase board

The "+1" after the cpu phases doesn't really matter unless you are seriously overclocking your ram.

note: VRM=phases, vrm just refers to the whole power management system, but the terms are usually interchangeable.

4 pin + OC'd 1090t = bad news.

You maybe should have invested in a board with 8 pin power like the TA890FXE for example.

Good luck though, I hope the best for you - and I hope you get a good replacement.

i am happy i have 16+2 power phase system...
wait did i jsut say that my mobo has 11 power phases more?
WTH?
why did MSI put just that few power phases on a mobo?

Maybe when they start using 8+2 Power Phase Design it'll be worth looking at.

MSI's gonna have a handful with this one
True, MSI have had problems (just check their forums) with all 4+1 designs, in the beginning, they even advertised the K9A2-CF-F as a 125watt-capable board. But when their inbox started flooding with people saying "My computer just blew up!", they changed their website to 'No 125w CPU support".
AFTER people had bought their mobos!

I wrote a letter to them, asking if they could RMA my Rev 1.0-board and give me a Revision 2.0 (or was it 1.1?) board instead, that they added two more power regulators I think it was, but they were the most arrogant tech-support I've ever come across, and I've spoken to a lot, since I've worked as a hardware-tech for years.I then asked the web dealer for a refund, but they had gone bankrupt, and their supplier (NOREK.no) wouldn't replace it because of scratches during transport, when the mobo was already dead! LOL

So, no pudding for you, MSI! Personally, I made a promise to myself to never buy anything MSI have made, and go back to ASUS,Gigabyte,DFI etc, because of their ability to at least answer their customers, and not try to squeeze the most pennys out of every board by under-designing the power phase design.
I use an MSI Radeon 5770 Card with factory-enabled voltageunlocking ( ! ) but I've never dared to even touch the switch. It's worth mentioning that I got it as a present. LOL

Sorry MSI, but you've brought it upon yourselves. Power-regulators are the most important component in an DC-design. Wierd that they don't recognize that, overclocking-"friendly" as they want to be recognized as.

My build has a 4 pin, and my Phenom II X4 955 has been running at 3.7-3.86 ghz 24/7 at 1.4875 *for 3.7* and 1.5375 *for 3.86* for a year 24/7 fine.

Although it does have 8+2...

reflex99 thx for the explanation.

As far as msi goes, I burned mine up on an ol x64 3700+ with just starting a mild oc without voltage changes... Bought a gigabyte to replace it and oc'd the heck out of it, and still going strong 4 yrs later.
