Sure, it's right after the page with the table of all motherboards affected and which firmware releases are patched.

Yep, this thing has 4GB and FF is no go. Same on 8GB machines, Safari or go home. Kinda :evil: as I've been using Firefox since it was Netscape Navigator in 1994 or so.

Re: Spectre-Meltdown barricade

I'm convinced that the main effect of this is going to be to drive new PC (Mac) sales due to browser mitigations which increase memory usage.

@notfred, thanks. Now thought really does need to be given to using separate machines for separate use cases :wink:

If you've been happy on the HD 5770, almost anything would do unless you want an upgrade. I second the recommendation against the GT 1030, it's not good. Same for old GT 710-730 .. but I'd suggest you stick to current generation or at most 1 back. If you want an upgrade, your PSU can handle most opt...

Don't know anything that goes to 0 RPM / 0 dB, but would e.g. the Mugen 5 PCGH at 4-14.5 dB do?

Obviously you might need the case and room cooling to be helping out.

Re: Transplant sanity check

If I read this correctly, your board supports some Ivy Bridge processors, which would get you more performance at even cooler temperatures. Nice idea, but not a goer thanks to it being too early a revision. Detailed nonsense explains. It's annoying, in part because the board is an RMA one (for the ...

Chess scales well. Apps use SSE for extensive bit-twiddling, and a fair bit of memory access for the hash tables. AVX and wide SIMD don't help much.

Raw performance is what matters in the end. Kinda. To users, what matters is ease of use, then support, then latency from job submission to job start.

Exactly. 1.5% of peak is laughable. It's a huge step in the wrong direction in terms of efficiency of compute, especially as power density and total power becomes more and more of a challenge. If so, almost everything Intel-based on that list of 130 machines is laughable. Most of the rest could be ...
