Hey Bucko, congrats on getting the card working!
krose & Fuzn, I did just what AS said not to do and spread a thin layer of AS5 across the heatspreader. The layer I put on is exactly as wide as the bottom of the SLK-948U. It kinda freaked me out when I saw that the the heatspreader was wider than the base of the sink, but it's working great. Anyway, with a Panaflo 92mm H my die temps are 44C idle and 46C load according to the Soltek HM. The biggest drawback to applying the AS5 this way is that it does make it more difficult to remove the heatsink. It's almost like a vacuum is created and you have to slowly turn the heatsink back and forth while pulling up on it with some moderate pressure until it suddenly pops up with a little "smack" sound. I was a little worried about that at first because I thought it might pull the heatspreader off of the chip, but I've done it a few times now with a couple of chips and it hasn't caused any problems (knock on wood). You gotta love the SLK-948U. The first installation is a minor PITA with the backplate and everything, but after that it's a piece of cake to safely remove/reinstall the heatsink.
Here's something interesting that I discovered last night - my gig of Ballistix PC4000 is suddenly able to run up to 235MHz totally stable at 2.5-3-2-10. I was messing around doing testing of 5X HT at 200 FSB and then at 210 FSB (where 5X maxed out with stability) at 1:1. I tried 220 and forgot to set the RAM to the 166 setting and the system booted but wouldn't load Windows. Now that's a big change from last weekend because the Ballistix wouldn't even post at anything over 210MHz even with max VDIMM and relaxed timings. I started testing all over again at 1:1, bumping it up 5MHz at a time, and was able to hit 240MHz using 2.5-3-3-6. Prime couldn't get past a couple of minutes, so I backed it down to 235 and it was totally stable. This was with the 3000+ so I popped the 3200+ back in and got the same results up to 230MHz (max stable FSB of the cpu at 1.55V). I checked and re-checked my notes from testing last weekend and every single setting in bios was exactly the same. Freaky, huh? I guess the Ballistix had to burn in or something before it would start to overclock with two sticks installed. Here's hoping that it continues to burn in and I can get it up to 1:1 at 250MHz with the 3000+.
