oic....that mean i must upgrade to 990fx chipset mobo?

yeah...running all 8 core

As goldfries mentioned, the power demands of AMD FX processors are too great for low budget boards with inadequate VRMs to handle. That "125W" TDP assumes that the cores are running at normal loads, but when pushed to almost 100% loads then that TDP is broken and the motherboard will start throttling to prevent the VRMs from failing (which can cause slowdowns, crashes, weird behaviour, and even shutdowns). Here is a recent example: Computers -> Technical Support -> HELP: My New PC always crash when after Full Load, HELP!!! (Hardware) the problems occurs when using Prime95 (which pushes the cores to almost 100%) with an AMD FX6300 on a low budget board with 3-phase VRM only(!). As mentioned in that thread, my recommendation is at least 4-phase VRM for 4-"core" and 6-"core" AMD FX processors, and at least 8-phase VRM for 8-"core" AMD FX processors...

Yups, you may have to consider higher end 990FX boards. If you want to use those AMD FX 8-"core" processors, then cannot skimp on motherboard quality (unlike Intel systems).

I've had my share of VRM failures, especially when the 8 core series just got introduced.

My Phenom II X6 1100T killed the MSI 790FX-GD70 board a few times until I fed up to do RMA.

The 790FX-GD70 uses 4+1 phase VRM. No matter how I RMA it, my X6 1100T will trip the whole system once it goes full load.

I gave up. It now runs an Athlon II X3 425.

no wonder...my pc now are not stable...i mean performance....so slow...i think better upgrade it to 990fx chipset..but...can u show me how much mobo 990 chipset???

want to ask..how much 990fx chipset mobo??i mean price???plz i need know it..

best buck vs perfomance should be from gigabyte GA-990FXA-UD3 (rev. 4.0)
http://www.gigabyte.us/products/product-pa...pid=4672&dl=#ov

take note rev 4.0 is most stabil n less isuee than other rev

it will hit you wallet around rm 470-RM499

ohh...that near rm500...ok...i will sell it my 970 then i will grab this.....where can i get??which shop?
