Re: Can you over-clock RAM with a non K CPU on a Zxx mobo?

I would disagree that Haswell is a lot more energy efficient. Yes somewhat but not that much. Though if you have an app making use of AVX2 that would probably help there... On the downside, you don't get the free 4 turbo bins any more with non-k cpus, so overclocking is out. (Certainly though gettin...

Re: 30-inch monitor recommendations

It looks like the Radeon R3 iGP supports UHD over HDMI (4k). It's a line item in your mobo's specs . However, I haven't seen whether it's using HDMI 2.0 or 1.4. The former allows for 4k/60Hz, the latter is 4k/24Hz. No AMD chip can do HDMI 2.0 today, be it discrete gpu or integrated (soon to change ...

Re: Quiet 4K multi-monitor DisplayPort graphics card help

AMD FirePro, either a W5000 (DP 1.2) or a V4900 (DP 1.1), any of them fitted with an Arctic Cooling Accelero S1 Plus heatsink. DP 1.1 can't drive 4k displays at 60Hz (only 30Hz).

Re: AM1

Is anybody looking at the recently available AM1 platform? Isn't Bay Trail even better? Not really though it depends what you're looking for. Bay Trail has lower TDP and indeed their peak power consumption is lower (should definitely be easier to cool passively). At idle it seems to be more of a wa...

I think HD6870 are a bit pointless these days. HD7850 are faster and have slightly lower power consumption (hence they are potentially easier to cool quietly), while not costing really more. Of course, if they are actually quiet depends on the cooling solution. There's probably some threads here aro...
