Home / I-Opener Areas / I-Opener Technical Stuff Full AMD conversion kit (group buy) available I have 8 kits available with CPU, res, switches and .012 ohm power resistor

Full AMD conversion kit (group buy) available (modified 0 times) DMasier Profile Hi, I've been lurking around for a couple months getting help hacking my IO. Thank you all very much for the help. Could not have done it without you. I'm currently running Win95 with a AMD K6-3 333MHz CPU at 233MHz (2 volts). Very reasonable performance now. As a "thank you" of sorts, I overbought my AMD conversion kit so I could help others who don't live near a Frys. (I live in Fremont CA.) I have 8 kits available. (Actually 9, but I'm holding one back because I'd like to get one more IO and convert it. I may change my mind.) Anyhow, I'd like $56 for the kit. I hope you feel that's fair for goods, time spent, etc. That includes insured USPS to you. Other than the CPU (Frys), it's all Digikey stuff. Here's what the kit has. 1x - AMD K6-3 333MHz AFK 1x - .012 ohm 1 watt 2512 power resistor 2x - 4 pos half pitch dip 2x - 200k ohm SMD 2x - 10K ohm SMD 2x - 102K ohm SMD 2x - 100K ohm SMD 1x - 24.9k ohm SMD (was supposed to be 2x but I goofed on qty. If I find some locally, I put another in.) I think that's enough to convert any model of IO, mess with voltages, and install any missing SW you may have (plus some extra stuff in case you drop one). It made sense at the time. If you are interested, please email me. Pay with Paypal. (kingmiwok@bigfoot.com) If you want to know about me, you can check my feedback at ebay (kingmiwok). Any questions, let me know. If I was wrong to post this here, please accept my apologies in advance. Thanks, Glen 10-08-2000 01:44:35

RE:Full AMD conversion kit (group buy) available (modified 0 times) DMasier Profile As requested, a procedure: Procedure: I have a V3b (V3 but with split voltage and (previously) a RISE CPU). Below I list the steps I took to convert over my IO. It believe they will also the cover V1 to V3 models GET READY: - Unplug unit - Open up case. - Remove EMI shroud. - Remove existing CPU. - Remove modem. WORK: Power Resistor: Do this to give your IO maximum possible available current at CPU. This is a tricky removal and requires two soldering irons at the same time on both ends of the resistor (what I did) - Remove R302 (near power plug) - Install .012 Ohm in R302 Split-plane: Mine was already split (V3b), but if you need to split yours (V3 and earlier) I BELIEVE you do this. Please verify elsewhere in this board. - Desolder R60 and R61 - Solder same to R184 and R185 Voltage Reference: This cuts the ref voltage (2.5V) to 2.0V for lowest CPU core voltage adjustment point. - Remove R342 (10K) - Install 24.9K in R342 - Install 102K in R343 Vcore adjustment: This enables the core voltage. - Remove R203 (if existing, I had a 1k there.) - Install 10K in R203 Set the core voltage. - Remove R202 (10K) - Install nothing in R202 for 2.0 volts core or - Install 200K in R202 for 2.1 volts core or - Install 100K in R202 for 2.2 volts core Multiplier Switch: For easy changing of CPU multiplier setting, install switch in SW1 - Remove R130 (0 ohm jumper) - Solder 4 position switch in SW1 location (near CPU) Bus Frequency Switch: For easy changing of the bus frequency, install switch in SW2 - Remove R208 (0 ohm jumper) - Solder 4 position switch in SW2 location (under edge of modem) NICE complimenting photos from Tackhead. Show switch settings and item locations. http://photos.yahoo.com/bc/tackhead_1999?d&.flabel=fld14&.src=ph TEST: Check for proper core voltage. - Plug in unit - Check voltage on pads of R60 / R61. (near top of CPU) - One side should read 3.3 volts. - The other should read your intended core voltage (say 2.0) Test CPU. - Install CPU - Boot it - Hit a CTRL-ALT-ESC to go into CMOS. Check CPU setting and voltage. FINISH: - Install modem - Unplug unit - Install EMI shroud. - Close up case. If I have any errors, PLEASE post them here. I believe everything above is correct to the best of my understanding. Please use you common sense if you suspect a problem. Thanks, Glen 10-08-2000 15:22:11

RE:Full AMD conversion kit (group buy) available (modified 0 times) DMasier Profile 3 kits gone. 5 left. Again, this kit is best suited for V1 - V3b owners. Thanks, Glen kingmiwok@bigfoot.com 10-11-2000 02:05:06

RE:Full AMD conversion kit (group buy) available (modified 0 times) ASPguy Profile | Email DMasier: When and how did you get a hold of the 4 prong dip switch and the 100k resistor? Last I checked, digikey was out on them. -aspguy 10-11-2000 13:01:58

RE:Full AMD conversion kit (group buy) available (modified 0 times) DMasier Profile ASPGuy, Actually got the switches several weeks ago and just didn't get the kit listed here right away. I had to wait on the power .012 ohm resistor anyhow. I think the 100ks were in the first batch. Plus I wanted to mod my IO first so I'd know it all worked. Glen 10-15-2000 01:14:12

RE:Full AMD conversion kit (group buy) available (modified 0 times) ASPguy Profile | Email Hey Dmasier, I spent 40 minutes trying to take the r302 resistor our to put on the .012 resistor. But that thing wont come out. I had 2 soldering irons working. How did you get it to come out. how much time did you spend on it? also, the 4 prong dip switchs. these dont go directly onto the board do they? the layout of the pads for it don't fit up to the dip switches. they are everywhere. did you have to use wires? and if this is so, they it wouldn't matter which type of dip switches were used right? -aspguy 10-16-2000 12:39:00

RE:Full AMD conversion kit (group buy) available (modified 0 times) UPSGuy Profile ASPGuy, To remove R302, melt both sides. Then use the soldering iron with a fine tip to melt one side, while applying pressure against that side to the right or left to dislodge the resistor. Now go and do the same to the other side. You might have to do this a few times in order to get the resistor off, but it works. The dip switches from Digikey do fit the pads correctly, and they do go directly on the board. Use some flux, then apply just a bit of solder to each pad, before attaching the dip switches. UPSGuy Power before the Storm 10-17-2000 19:43:12

RE:Full AMD conversion kit (group buy) available (modified 0 times) Turbo3 Profile Don't need to remove the old one just soldier the new one on top. I have tested this and it works. We just want a lower value total resistance. As long as it is less than or equal to 0.012 and not zero (per BadFlash) you will get all the current the iopener can supply. 10-17-2000 19:51:55

RE:Full AMD conversion kit (group buy) available (modified 0 times) DMasier Profile ASPguy, My experience was nearly the same at UPSguy. The switches fit fine, actually the easiest solder to do. A simular style would probably be fine. It did the double iron bit for the big resistor and it popped off at some point, maybe 40 seconds of various trys. I used LOTs of solder wick (mistake?). I actually had to re-wet it at one point because I couldn't getting heat into it. Just to comment on the resistor stack idea by Turbo3... actually a clever thought. Much easier to do. Wish I had though of it. However, if you do Ohms law on it (two resistors in parallel) you will get about half of the resistance (about .006 ohms), plus tolerance considerations, blah blah blah. Anyhow, it might get close zero ohms. I don't really understand the repercussions of doing that but if it works, who can argue. Glen 10-17-2000 21:52:37

RE:Full AMD conversion kit (group buy) available (modified 0 times) DMasier Profile Also, I'm down to maybe one kit. (I'm holding a couple for promised payment.) Anyhow, if you've been thinking about it, but holding off, you might want to email me pretty soon. Thanks. Glen kingmiwok@bigfoot.com 10-17-2000 21:56:35

RE:Full AMD conversion kit (group buy) available (modified 0 times) ASPguy Profile | Email Dmasier, funny, i was looking at either my sw2 or sw1 pads on the iopener and they weren't lined up the way the dip switch were. they were like everywhere. One pad here, one pad there. not uniform like the dip switch prongs. anyways.. i'll check i again, maybe i may have looked at something else. how odd, i could have sworn what i saw was right. hey, can't i just use wires and a radio shack dip switch instead? -aspguy 10-20-2000 10:27:17

RE:Full AMD conversion kit (group buy) available (modified 0 times) PVAMan Profile | Email Hey, if there is still a kit left i've got a version 3 and i'd love to upgrade it. 10-23-2000 18:49:19

Unsoldering SMD things (modified 0 times) Russ Profile I picked up some wick stuff from fry's, seems to help, its basically braided copper that absorbs solder with capilary action. I was able to work with very small components with a radio shack soldering iron. I saw fry's had a SMD removal kit, didn't buy it, might be helpfull. Also, the fry's in tempe has the AMD K6-3 333AFK in 10-24-2000 00:31:57

RE:Full AMD conversion kit (group buy) available (modified 0 times) ASPguy Profile | Email PVAman, i'm putting together another group buy, just email me to inlist your address . studmufn@hotmail.com 10-24-2000 11:30:17

RE:Full AMD conversion kit (group buy) available (modified 0 times) DMasier Profile PVAMan, If you have not already emailed me about a kit, do so. I MAY have one left. A couple people have 24hrs to figure out payment. If they are not able to, I have one for you and can ship immediately. Glen kingmiwok@bigfoot.com 10-24-2000 23:56:50

RE:Full AMD conversion kit (group buy) available (modified 0 times) DMasier Profile Hi, It looks like all the kits are gone. Thanks for the interest. Glen 10-29-2000 04:02:18

RE:Full AMD conversion kit (group buy) available (modified 0 times) Johnson Profile Again, if anyone is doing another CPU Upgrade mod buy...PLEASE LET ME KNOW ASAP!! jackson_1@hotmail.com 01-24-2001 00:42:39
