The first memory M#"KHX3200AK2/512, note the "A" has listed timings of 2-3-2-6-1T. the other M#KHX3200K2/512 Non a, has listed timings of 2-2-2-6 1T. as listed on newegg and the Kingston website. I called kingston yesterday and the customer rep I spoke with said that there was no way to tell if you got bh-5 chips or not until you buy them and take off the heat spreader. I spoke with a tech guy too. They also don't sell the non 'A" without a heatspreader. I then called Mushkin and they told me that all Levl 2 memory had bh-5 guaranteed. She also said that Mushkin will proly change the name when they run out of bh-5 chips. Like instead of calling it black Lvl II, they would call it LvL 3 or something. I also learned that there is no such thing as PC3500. Its just PC3200 guaranteed to run at that speed and at 433 FSB. So I whipped out my credit card and bough a matched pair of Mushkin PC3500 DDR433 512 sticks. I'll let you know how they work. In the end i feel you get what you pay for.
