What's the solid choice nowadays for AM3+? - Page 5

post #41 of 183
I have one 990FXA-UD7 and it´s the worst AM3+ I´ve ever tried. Never used it since I got it for Gigabyte competition at HWBot and definitely never will.

It´s the most overpriced board there is unless you absolutely need six PCI-E slots.

Think there were a couple versions of the 990FXA-UD7 hence they may of produced a decent board...... by luck.

Gigabytes were always a choice of extreme luck, when you first take it out of it's retail box and plug it into your Power Supply thinking.gif .

Be glad to take it off your hands.... Send it on over!

Would rather LN2 on that board than a good working CHVZ board any day. That's the reason why I had purchased the M5A78L (about 50$) and beat on that instead. Got tired of ruining 200$ plus motherboards just to get some clock speed.

The worst one I ever tried was made by biostop err biostar.

My love for Asus though extends far beyond compare of any other board manufacturer. I mean who'd thought 4+1 Asus board would be benching at 7ghz and beyond?

Benching at 7GHz and beyond on 4+1 phase board?
Please post a Cinebench run or any other fully multithreaded benchmark done at >=7GHz, with a FX-8K series CPU on 4+1 phase board.
Gotta see it since the newer C5FZs can´t do that either. The old ones could though wink.gif

2 cores 2.0v.

Benchmarking on one core is still benchmarking is it not?

Also, I don't have enough PSU for all 8 cores. 1000w Antec CP series doesn't have it on the 12v rail.

Max clocks increased from 7500mhz to 7600mhz going from 850w to 1000w with the same set up.

I just don't have the moneys like some people to throw at it. I do the best I can with what little I have.

Here's the best I pulled off on 850w PSU. Probably could have done better.... but I'm no magician you know wink.gif

4+1 VRM Asus M5A78L MX PLUS

Does this tickle your fancy?

If you have the patience to wait for me to test it for a while, I think I'll try the MSI 990FXA gaming motherboard and I'd be happy to give you the lowdown.
It's the right color scheme and I see they are rated to support the FX 9xxx's now.

@Stilt - Here is 7ghz plus 4+1 benchmarking. No it's not all 8 cores, But I never said anything about all 8 cores, that was your idea.....

OH you noticed steam? Yes I did game at these frequencies. Just in case you where wondering.

Gigabyte 970A-UD3P is electrically fine, however the bios is a complete bug fest (applies on all Gigabyte AMD boards).

With sufficient cooling all of these will handle a 4.7GHz FX-8K CPU without any problems.

I think I agree 101% with this post. I have tested several AM3+ boards and Asus are the best hands down. Spec wise Gigabyte boards are a match for Asus but Giga has dropped the BIOS ball really hard with AM3+.
There is a newish Asus model that I haven't tried though.

Does seem low end admittedly.

At 7.2GHz / 1.968V a FX-8K series CPU with low leakage characteristics consumes around 380W of power during Cinebench, in floored LN2 temperatures.
If you stress just one or two cores, the power consumption will be around 1/4 of that (~95W) for the VDD_CR circuit and at voltage that high it means only <49A of current.
Even 2 phase VRM would have no issues in handling that, especially when the VRM is cooled close to sub zero temperatures through the VDD_CR / NB power planes.

So saying that 4+1 VRM handles a FX-8K series CPU running at 7.2GHz / 1.968V is pretty inaccurate IMO, unless you specifically specify "in single threaded or non CPU intensive workloads" wink.gif

That would be great. Patience I have.

I've been to MC already and just couldn't pull the trigger yet.

Meanwhile I did grab a kraken g10 to toss on a r9 290 tonight so that'll be fun smile.gif
