Hello. Well, it´s one of my first post here on THG forums.
I live in Argentina. Now I have a P3 750 Mhz (slot 1) on a Soyo SY-6VBA133. The next month I will be buying the last part of my new system: an NF7-s mobo (currently I have this parts: Athlon XP2100, GF FX5200 from Albatron, 120 Gb. HDD from Maxtor, 2 DDR 333 memory modules from Samsung (CL 2.5), Topower Case, my old 40 Gb HD, and my old optical units (Pionner DVD105-s and OptoRite 16x12x40 CD-RW). Well, looking at the fact that I will sell my old system, I started to overclock it, as a test for ocing my new system. As you know, my mobo supports 133Mhz FSB. But my CPU is a 100Mhz FSB one. So as the multiplier on the intel CPUs is locked, this is my only choice: the FSB. With stock cooling I reached the non-despicable speed of 900 Mhz (120 Mhz FSB). But the CPU temp at that level was too high, and the system was not fully stable. (it was runing at ~1.69v instead of 1.66 wich is the correct voltage for my processor). The first thing that I do is change the fan. I replaced the standart one with the one that I buyed for my Athlon: a Delta of 38CFM@6800RPM. Then system turned fully stable and bery noisy. But the temps still high. So I took the processor´s cartridge and dissasembled it. Look at the aluminum heatsink and... what is it? a THERMAL PAD!. Quickly I removed it and, as I readed in some sites, used a sandpaper to make the heatsink so plane as I can. After half hour of work, it have a much more plane contact surface. I cleaned the proccesor´s core with alcohol, added a thin layer of thermal paste, put the heatsink back again... and I´m ready to go. Start the system, windows booting... and what I see during the last step of the OS boot-up??... MBM sayin 38 degrees !!! Looking at the previous temps (around 42 at idle, and 70 at full load) It was a bery great difference. So I continue overclocking... reached 930 Mhz at 124Mhz of FSB and... that´s over.. my BIOS does not have an higer option. But.. wait a minute... i tooked the Soyo´s guide... and... yeah! there is a jumper combination that tells the procesor to boot-up a 133 FSB, and thrus,another that enables all the FSB options on the BIOS. so I do that. Re-jumped the mobo... pushed the power button... and... beep... BIOS POSTED!. Enter the set-up, set 133 FSB, CL 2 an DRAM frequency at 133 (My 128Mb module is PC133)... and... booting... what the hell... it loaded windows!!!!. Runs stable. So I just start "Enter the Matrix" and start playing. At this point, the CPU was working at 1.70v. played some minutes.... and.... locked Up. GRRRRRRRRR. Well, the last option: +10% of normal core voltage. Reboot, set the Vcore option at +10%... and boot!!!! It currently passed the 3dMark 2003 test stable 3 times. And also I can play "enter the matrix" bery fine. And trus, the PCI clock and AGP clock run at standart speeds!!!! (remember that the setup believes taht is a 133 FSB processor). All my fist attempts to increase the FSB (before changing the jumpers) was overclocking the PCI bus and AGP port. They worked at a max speed of 41 for the PCI and the AGP at 81, both never showed any problems.(even at 81 Mhz of the AGP, it loaded much more fast the textures onto the 128 Mb of the FX5200). I have a Sound Blaster PCI-128 sound card, and a "el cheapo" 3com winmodem.
Now the system still runing bery stable. Now the max temp is around 45/47 Celsius degrees. I´m bery pleased, and I´m thinking to add a cooper base to the heatsink, in order to change the fan with a less noisy one, and reduce the temp.
Somebody reached the Ghz on slot 1? ;-). I can say YES!.

P.D.: sorry for my english.
