That's the AMD version of Silver's (Intel) board. Apparently we both have good taste. Yours: https://www.asus.com/us/Motherboards/M5A97_R20/overview/ Mine: https://www.asus.com/us/Motherboards/P9X79_LE/overview/ Bought Silver's used off eBay, CPU included... was the best sub-$200 option at the time, and haven't seen anything more exciting since in that price range. Now if only I'd finish moving computer so I could actually USE the thing...!! (I kinda prefer MSI's feature set, and suspect they have better durability, but the higher-end MSI boards rarely show up used.) > The LLC stuff sounds like a possibility only because deals with voltage. > which _may_ be the USB lockup.

The cable > has probably been moved to a different port over time. The very first shoulda-been-a-clue with mine was that the USB3 hub plugged into the USB3 add-on card quit working. Thought it was the hub, replaced it, new one worked... for a while. Pretty soon it didn't work either. And then I got around to testing the "dead" hub with another PC, and found it works perfectly. By then all Tarnish's USB ports had quit and I'd had to resort to corded keyboard and mouse. And that's when it got swapped for its twin, which doesn't seem to have the problem. Discovered another problem, tho -- Tarnish (old Silver) had 4GB RAM because WinXP 32bit can't use more than that anyway (and it was what was handy at the time). Tried to give it 8GB since it's now hosting PCLOS, which benefits from more RAM. WOULD NOT BOOT! Guessing it's the same issue -- added power draw was too much for the defective circuit. Ah, well... when I get completely moved into New Silver, Cash can have its old job back (secondary PCLOS streaming box) and Tarnish can run ReactOS (which runs well on Tarnish, and doesn't like it when there's more than 4GB RAM anyway). > KM> Nope, it doesn't bypass -- USB is still USB, apparently.

By what I was reading sort of thought so: PCI to Southbridge, so > if Southbridge is the problem not bypassing. Yeah, I'da had the same thought, if I hadn't already experienced the above fail!! After all, you can bypass a dead onboard NIC with an add-on card (done that twice), why not same for USB?

Yeah. It's been slow to penetrate baseball, and each spasm of Stupid has tended to quickly peter out, but when there's so much top-down Thou Shalting... hopefully this crap will die down everywhere without devolving into civil war. :( > > KM> ... so I can have two games going at once, since I haven't > > KM> figured out how to get the Dell with the updated PCLOS to speak > > KM> to a 2nd monitor.

Oooh, thanks, I'll give that a look (when I don't already have two baseball streams hogging my shrinking connection...) Did I gripe about CenturyLink yet? they changed my loop -- it got shorter, but my connection went from stable 5Mbps to unstable 4Mpbs, and am told by their now worthless tech support that it sucks to be me. One of the fixed wireless companies is now almost competitive price for faster connection... might have to switch. þ RNET 2.10U: ILink: Techware BBS þ Hollywood, Ca þ www.techware2k.com --- QScan/PCB v1.20a / 01-0462 * Origin: ILink: CFBBS | cfbbs.no-ip.com | 856-933-7096 (454:1/1) .
