  1. Take a close look at the DIMM slot with a magnifying glass and strong light because you may see corrosion, lint, or even a bent contact. Don't clean DIMM slots with cotton swabs but instead get some cardboard the same thickness as a DIMM edge connector. Apply alcohol to it and insert and remove it several times to clean the slot. Most retail DIMMs are marginal because they're made from chips that are slower than the module ratings or unbranded chips (factory rejects).
  2. I like any module where you can easily read the part numbers off the chips and those part numbers are from the actual chip maker, as opposed from the module maker (unless the module was made by a chip maker, like Micron/Crucial or Samsung). Sometimes you can find such modules in a local store, but generally only Crucial and Samsung brand modules are like that.
  3. The Ultra employee who said that had no technical qualifications. I don't think anybody at Ultra does because several years ago, back when they still had a forum at their website, I asked if their V-Series PSUs had thermal shutdown. They had to refer to the actual manufacturer, Wintech, who told them the PSU didn't have that protection but would inherently start cutting back on power at 55 Celcius enough to shut down before burning up (reassuring). My only Ultra PSUs are some old ones made by Wintech that were free after rebate. One came with a couple of ground wires that weren't soldered because they were too dirty, and a capacitor on the low voltage side came really close to touching a 120VAC lug (that capacitor was bent down for greater clearance in the other PSU, which probably came from a different factory or production run). Also the fan wouldn't turn on if the PSU was cold and the room temperature was oo low -- bad design. If you bought the PSU with a credit card, do a written "billing error" chargeback and say you do not "accept" the product because it's not only defective but so is it's warranty (you paid for a warranty but didn't know it wouldn't be honored). Mail this to the special address for billing inquiries because that will put the credit card issuer under certain federal legal obligations, and they'll be responsible for correcting your bill, regardless of the merchant paying back the money (but don't be surprised if the card issuer denies that -- they often misinform consumers about their rights). Your only obligation is to _try_ to return the merchandise to the dealer. And while you should provide proof of purchase, a copy of the warranty, any advertising claims, etc., you're not obligated to do so, contrary to what the issuer says. If the card issuer gives you a hard time and it's a Visa or American Express card, contact those companies because they're good about making their member banks comply. Mastercard seems to be a lot worse.
  4. What memory are you using? If it's got heatsinks on it, the chips don't have the part number or logo of a chip maker, or are factory overclocked, be suspicious. You want something like Samsung or no-heatsink Crucial modules for testing.
