A 125W TDP CPU on a 95W TDP Motherboard

Hi guys! To make it short: I've a 125W TDP CPU(Phenom X4 9750 2.4GHz) on a 95W TDP Motherboard(MSI K9N6PGM2-V2). For now the PC works, but will it work for a long time?
When I bought the components I didn't notice the TDP thing, also because on the CPU Support list the CPU is in there.
What do you say guys? Have I to change it very soon?

Yes and no it depend's on how much load the CPU is drawing so don't do any strenuous CPU bench test that will cause the CPU to draw it's full 125W as you may end up cooking the POWER mosfet's..

Under normal load It should be fine, Looking at the PIC of your mobo there is no heat sink on the FETS witch could be a bad thing what type of CPU cooler are you running this could be the difference between life and death for this MOBO

If its on the support list I would not worry about it to much. It is kinda odd that they say 95w only and then list 125w CPU's. I would shoot MSI support a e-mail just to be certain though.

Buy a fire extinguisher.

Joking aside, you should be fine unless you're running Prime95 or other CPU intensive load for extended periods of time.

I also have this CPU, which is coded as Agena.
There are two variants..95W and 125W. As far as I can tell XAJ in the CPU code indicates 125 w and WCJ 95W.
I also understand that it only supports DDR2.
Not planning to pop it into a mobo that only supports 95W.
This page helps a lot.

and this one:

Hope it helps.

Sorry but maybe i should have been more specific.
Not talking about that MSI board in particular, but the question is: what is the danger of putting one of these into a mobo that only supports 95w, like the Asrock N68C-S ucc as an (bad) example?
This CPU is on the Asrock support list, but of course there are two versions of the same cpu, which can be confusing.

The motherboard BIOS won't support it and if you do, the CPU will not function. You could theoretically destroy the voltage regulation circuit components, but they are usually self-protected.

Sorry to be pedantic, lol.
But this is what I thought and actually tried this 125W in a mobo that supports UP TO 95W and it came up with a warning and shut down automatically.
I'm in the PC business and frankly it's not worth the gamble, with so much good hardware at risk.

That is what should happen with a good BIOS implementation. Also, this thread is a year old.

Not in MSI's case for AMD boards. It's more than theoretical. It's a reality. There are countless issues of MSI AMD boards failing in the overclocking community for this reason.

I would NOT overclock at ALL on that board with that CPU, and I'd honestly be nervous just using it as is. If (maybe it's a case of when) your board fails during use, the board should be your first suspect. Check the VRM area for burn marks if it happens.

I hate to sound so dire, and normally I'd say you be fine, but MSI has a huge track record of this happening on AMD boards, so I'd be very careful.

I am guessing that if they put up 125w - 140w CPU on the support list along with what BIOS to use with them ..it should be ok, as long as you don't do any OCing..

Phenom X4 Agena HD9750WCJ4BGH 9750 200 2.40 2M 2M B3 95 7309v25.zip
Phenom X4 Agena HD9750XAJ4BGH 9750 200 2.40 2M 2M B3 125 7309v20.zip

its on your CPU support list..
