Anyone,

I want to upgrade my CPU. I am looking for FX6300
Will FX6300 bottleneck PNY GTX660 SLI? I am thinking 8350 and 8320 but I heard it's not good on my MSI mobo.
May I ask is my XFS 550W PSU good enough for the 6300 and GTX660 SLI?

I have:
amd phenom x4 925
MSI 9701-g46 mobo
master cooler Evo,
4x2gb 1333 DDR3 ram,
XFS 550W PSU.
PNY GTX660 GPU


Thanks for helping and advise,

I am a gamer and want a pc performance as close to PS4 or Xbox one. I currently have amd Phenom x4 925. When I play watch dogs, it is so laggy and struggle when driving. The FPS went down to 10-20 FPS during driving. I am thinking that maybe cause of the CPU. That's why I am thinking to upgrade my CPU. I tried to OC the 925 but I can't get stable beyond 3.1GHZ.

PS. micro center has free Gagabyte GA78LMT/USB3 mobo when purchase FX6300 which seems a good deal.

Thanks for helping and advise,


I own and use an MSI 970A G46. Overclockers beware. The VRMs (voltage regulation modules) are notoriously crappy. I use an FX8350, and I basically gave up on overclocking for fear or losing a $200 CPU to a $60 motherboard. I would get the 6300 with the gigabyte, then, if you have to, sell the 6300 unused and buy an 8350 or 8320. If you plan on overclocking though, keep in mind that both of those processors will need a better cooler-probably liquid or a large air cooler like a Noctua.

XFS 550W PSU good enough for the 6300 and GTX660 SLI? Should be , but I usually recommend 650w.

Thanks for the reply. This is a great forum with a lots of great people.

May I ask if 6300 OC to 4.1 GHZ will bottleneck on GTX 660 SLI ?
I may consider getting the second GTX 660 for SLI.

Thank you,

This is a common AM3+ issue, after some research with my FX 6300 underclockings, I have found out that you will need a minimum of 970 chipset, MAKE SURE the VRMs have a heatsink, and the motherboard sports 8+2 power phases.

This is fault of AMD bad efficiency. They have huge clocked chips that draw tons of power, and motherboards have problems to keep it up.

That board has a poor thermal design , get this one.

I am a noob. May I ask what heatsink (brand name and type?) do you suggest for the VRMs on the MSI 970A G46 motherboard? If I don't buy the heatsink, will the FX6300 Over clock burn out the stock motherboard? I have bought the Master Cooler Evo for CPU.

Thanks,

That motherboard already have heatsinks on the power phases...

The worse thing is I had the GTX660 card and I was thinking to SLI in the future. There was on Sale for that MSI mother board which support SLI ($60). I have bought it and now I can't return it for avoiding restocking and return shipping fee. T_T
Too late for me now.

Yes, only the 990FX motherboards will provide a x16 config in two PCIe lanes.

On the note of MAD chips being incredibly innefficient- competivite unlocked i5s have stock power draws around the same amount. AMD's 3rd gen of AM3+ CPUs are supposedly going to feature greatly lowered power consumption. Quick question for the op-I am no sure if the 212 Evo will be enough for a 4.1GHZ OC on that chip. SR71-any recommendations on the air cooler side?
