AMD CPU under 100$

[TeknoBug]

That board has heatsinks for northbridge and soutbbridge, but not on the VRMs:

lol that's a rev1 and rev1.2 board, rev3 has a heatsink on VRM.

rev3 has a heatsink on VRM.

Okay, but then you mention the board overclocks FX-4350 easily to 4.7 Ghz. (So I doubt overclocking FX-6300 should be a problem)

My Gigabyte 970A-D3 with 4+1 and heatsink didn't play nice with OC'ing a X6 1090T, FX 8320, 8320E but OC'ed a FX 4350 easily to 4.7GHz.

How much overclock did you attempt for the X6 1090T, FX-8320, FX-8320E?

It just OC's the 4350 no problems no adjustments to anything other than multiplier. I have no explanation.

1090T 3.9GHz, can do 4GHz with ridiculous vcore settings which isn't good idea 24/7, 8320/E to 4.2GHz but VRM got warm (can't remember numbers).

So when you buy AMD you need to buy the right mobo with the right revision with the right ancient chipset so you don't blow the VRMs. Plus keep an eye on the volts as looking around here auto volts on FM2+ is all wonky if you go APU. May as well save another $100 and buy a 4460.

 

[DrMrLordX]

Uh, no. The whole point is to NOT buy el-cheapo boards with chipsets that only marginally support the CPU/APU and then fret over VRMs. Voltage problems on FM2+ can easily be remedied in the UEFI.

OP bought an 860k so it's too late to indoctrinate him now.

For the people reading this thread besides the OP can you please clarify what this means?

And what specific problems it causes.

I wouldn't exactly call one example out of 273 reviews a trend.

P.S. That AM3+ 760G board I linked has a four egg rating too. So yeah, I don't think we can call it a bad board. In fact, I've seen more expensive FM2+ boards (including A88X) with worse ratings on newegg.

That s because the FX4350 at stock is not a 125W TDP chip despite the official specs, FTR at stocks it is 80W under Prime 95 and 65W under MT loading.

At 4.7 and with regular Multithreaded loading it is within 100W and still within 125W with Prime 95.

So it is no surprise that a 125W MB can withstand this chip at extreme clocks, but it wouldnt equally support an FX6350 for instance since the limitation with Prime 95 would be at 4.3Ghz.

I sport this bad boy:
http://www.amazon.co.uk/MSI-760GA-P43-FX-AM3-ATX/dp/B00G6AYVHQ

and have fx6300 oced to 4.5Ghz.

I think this is the cheapest am3+ mobo with the most MOSFETs.

Since there s SATA3 for the HDD and USB3 ports it has the essentials, with onboard GPU this is an economical card power usage wise, the 760G has relatively low TDP given the included graphics.

The FX 83xx E have been specificaly released for such cards according to AMD, but if one wants to overclock that s another matter.

Also if you dont Prime 95 your set up the FX63xx at 4.5 is still at 125W max with heavy but regular MT loading like Cinebench, Fritzbench or other such tests.

 

[Erenhardt]

This cheapo board is rated at 140W Phenom II X6, so it should run 8350 with some OC'ing. Maybe one day I will grab 8 core fx and see what this board has to offer.

Bought it some time ago for 50EUR.

Since there s SATA3 for the HDD and USB3 ports it has the essentials,

Since it uses a 3rd party controller (Asmedia... D for those SATA3 ports, they'll be lower performance then native southbridge/FCH provided ones. The USB3 controller is also 3rd party, so its limited by available PCIe bandwidth.

with onboard GPU this is an economical card power usage wise, the 760G has relatively low TDP given the included graphics.

Not impressive at all when you consider FM1/2/2+ (and Intel for that matter) fits both northbridge and graphics within the APU/CPU TDP.

To say the integrated Radeon (not even HD) 3000 is obsolete is a polite way of putting it. It doesn't even have HD video decoding.

Oh for goodness' sake. Stop being so deliberately obtuse. You're feeding ammunition to the Intel trolls.

I understand the point you made about old components (besides the chipset) in this post:

http://forums.anandtech.com/showpost.php?p=37401847&postcount=140

How is the chipset being older specifically a detriment though?

It means someone's dumping old inventory, whether it's old components or just flat-out old boards. Those ICs were not designed to handle Bulldozer or Piledriver, and the VRMs and other board components certainly weren't either.

But some 760G boards like the one I linked have new revisions released in 2014 or later. In fact, even revision 5.0 of that board I linked supports 8370E on the first BIOS. So on a late manufacture 760G it is very likely things like VRMs and other components have been updated. That potentially leaves only the chipset as the only "old design" component left on the board.

1090T 3.9GHz, can do 4GHz with ridiculous vcore settings which isn't good idea 24/7, 8320/E to 4.2GHz but VRM got warm (can't remember numbers).

That is a pretty good result IMO.

P.S. Was that using a CPU cooler that doesn't blow air on the VRMs? (eg, Coolermaster Hyper 212, etc)
