In the mail I just got my Fop 38 and a 92mm sunon case fan from thecoolerguys. Anyway I have the heatsink and fan installed and I can get my computer to boot just fine. Currently at 800mhz from 700 my cpu temp is 26c. I've had it going at 850 with my old one but when I try lets say 950 with multiplier 9.5 and the votage around 1.80 and 1.85, I save the cmos and then restart but when I restart the computer says 700 at 7.0. Is this as far as the chip will go. I really need to get it too go higher or the heatsink and fan were a waste of $. Any suggestions?
On the top of the CPU (you need to take it out again), you will see 4 tiny bridges labeled "L1". These are what AMD uses to "Lock" the CPU to a specific clock multiplier. These connections must be repared. The easies way to do this is to draw several times across each connector (without shorting between two differant bridges) to reconnect them. Once all four are "fixed" you can go into BIOS and set the clock multiplier to user defined and set the multiplier to whatever you want. If it will not run at a speed, it will lock up, run unstable, reboot, or fail to boot or post. Extra voltage helps this, but keep the temp below 40'C if possible (50 works, but is harder to keep stable).
The COMPUTER is your FRIEND!

Ok, well I'am just running a multiplier of 8 right now so there is no fsb o/cing. Now some of you are saying that my L1 bridges aren't closed enough but would that affect my abilty to go above 800 from a orig 700 duron? I've tried all of the voltages above 1.660 with 850, 900, 950 and I tried 1gig with 1.85. Could my cpu be limited to this? I did have it going at 850 with my old heatsink and fan from Globalwin.
All of your bridges are not closed. I had the same thing happen when i tried to use a conductive pen. I use a magnifying glass to look at the bridges during and after connecting the L1 bridges, they looked good. I set the cpu back in and overclocked it to 700@750 but when i tried 700@800 it went back to 700. I then cleaned off the conductive pen goop and used a #2 pencil and tried it again. I got the cpu to 700@1059. It was stable but wouldn't shut down right. I sure didn't like that. I also tried different mhz settings like 850, 900, 950, 1000, 1050. All the settings i tried i ran for one day and they were all very stable. The only setting that gave me trouble was the 1050, the machine just wouldn't shut down. Long story short make sure the L1 bridges are connected. By the way that 25C is a great temp you sure that isn't your case temp instead of your cpu. The reason i ask is i have the same globalwin fop 38 and my cpu temp at 700@850 with vcore default setting, is at 32C and that is with two 4" 85cfm case fans blowing and sucking Hope this helps in some way, good luck.
Don't hate me cause i'm beautiful.
Ok looks like I will be reconnecting the bridges again. I'm pretty sure that is my cpu temp because I'm running mbprobe and also cpu cool. I'm also checked in the bios and it has be around 27c. Right now my cpu is dropped down to 24c when I've been idling typing this message.
Well after reaplying the pencil trick this morning I was able to get 850 mhz, but I will hope a I can get 900-950 cause that was the point when buying my equipment. There is anything that needs to be changed with the I/o voltage also?
BTW I think my FOP 38 wasn't getting enough power cause after this morning when putting my mobo back to gether the thing seemed to whine alot louder
