i-opener version and cpu upgrades (modified 0 times) msdek Profile I have 3 i-openers, and I would like to upgrade one of them to a K6-450 (or a K6-500, if anyone if that is possible...) Anyways, I've spent a lot of time searching through the messages, and have just gotten more confused about the upgrading process. Which one of the following units would be the easiest to upgrade? Unit 1: Winchip, no goop, intact pins, nothing but net screen. I think this is a V1, and it currently runs linux off of a hard drive Unit 2: Rise 266, no goop, intact pins, new boot screen, Yamaha sound chip. I flashed this with the patched V5 bios on fr44dr1ve, and it will boot Jailbait or a hard drive successfully. I think this is a V4, but I'm not sure. Can anyone clear this up for me? Unit 3: Rise 266, no goop, intact pins, Yamaha sound chip, and SW4 switch below CPU. I have not modded this one at all, but I am thinking that it may be that easiest one to upgrade. I have no idea what version number it is, though. It's like my unit #2, except #2 doesn't have the SW4 switch (to set the CPU voltage). Any ideas? So, which of these would be the best for installing a K6-450 cpu? I will run Linux on the upgraded system, so using SoftFSB is not possible (unless anyone knows of any alternative for linux...) Thanks 12-09-2000 16:31:50

RE:i-opener version and cpu upgrades (modified 0 times) BadFlash Profile | Email 2 & 3 are both V4's as they have a rise 266 and yamaha sound. The V5 has a different sound chip. Unit 3 is your best bet. You can use the dip switch to set the voltage for your K6. You will also need to bypass the current protection to get above 6 amps to the CPU. The K6-II 450 is pretty power hungry, so I wouldn't advise going over 250 Mhz without doing some serious power supply mods. Running a K6 at 450 or 500Mhz will cook the board. The K6-III+ 450 is a better bet. See http://www.linux-hacker.net/cgi-bin/UltraBoard/UltraBoard.pl?Action=ShowPost&Board=technical&Post=1753 12-09-2000 17:45:00

RE:i-opener version and cpu upgrades (modified 0 times) msdek Profile How would I set the cpu speed? If I chose to, what exactly would I have to do to support 450 MHz? 12-09-2000 18:05:36

Which CPU for v1? Running WinChip2 now - too slow for the kids! (modified 0 times) blunlimited Profile I'm looking for some advice... I have a v1 that is running a WinChip2 with Lasagna fan with WinME on a Fujitsu 3GB. After 5 months of use in this config, usually on 24/7, I have noticed that the unit is not getting used regularly by either myself or the family (too slow). I am looking to do a CPU upgrade (again) and am numb in the head over all the info contained on the board - any quick advice on which cpu would be my best bet - I can do board soldering... or I should say the maintenance department at work can help me out there. Any advice would be sponged in and used. 12-12-2000 03:39:52

RE:i-opener version and cpu upgrades (modified 0 times) BadFlash Profile | Email The first link shows pretty much waht needs to be done to support a K6-III+, there are other similar links if you search for them on how to do a V1 and how to reduce the CPU voltage below 2V to draw less current. With this change you can get to 350 mhz. CPU multiplier with the K6-III+ can be selected via software in windows via autoexec.bat To go to 450MHz you need to de-solder the tab on Q16, raise it to verticle and add a small heat sink to it that touches nothing as it will be electrically hot. Between it and where it was soldered you need to add a 10 watt .13 ohm power resistor. Turbo3 has pictures of his. I think he overdid it with the heat sink, but you can't argue with success. 12-12-2000 10:58:20

RE:i-opener version and cpu upgrades (modified 0 times) msdek Profile is this mod specifically for the K6-III? What is(are) the difference(s) between the K6-II and the K6-III? 12-13-2000 10:40:08

RE:i-opener version and cpu upgrades (modified 0 times) Programmer Profile k6-2 no cache; not very suitable for the IO k6-III; has cache; intended to run at ~2.2v; is power hungry; mostly OK k6-2+; 128k L2 cache; intended to run at 2.0v; low power; multiplier soft selectable; good deal k6-III+; 256k L2 cache; intended to run at 2.0v; low power; multiplier soft selectable; Super good deal!! I would not recommend using anything less than a k6-2+; it's power saving features, on die cache, and the fact that the bus is soft selectable, make the (+) series very suitable for the IO. Many people on this board have managed to get their systems running well with the k6-III (no +); but they find that they have higher heat and there is more to be done to get them to higher speeds. 12-13-2000 13:13:52

RE:i-opener version and cpu upgrades (modified 0 times) ASPguy Profile | Email are the amd k-3 333mhz afk chips from frys a k-III+ ? Where can we get the k-III+ at? is there a huge difference? 12-13-2000 22:41:51

RE:i-opener version and cpu upgrades (modified 0 times) Linuxguru Profile | Email The AMD K6-III/333AFK at Frys is not a '+'. However, it is an excellent choice (IMHO, better than a K6-2+) because it has a 256k L2 cache like the K6-III+, costs only $29.95 and runs comfortably in the I-Opener at 200 or 266 MHz with minimal mods. It's not really power-hungry, except in comparison with the K6-III+ (which costs almost twice as much). 12-14-2000 01:42:58

RE:i-opener version and cpu upgrades (modified 0 times) BadFlash Profile | Email Just remember that the K6-III can't change the multiplier via software. This limits the ability to go above 300 Mhz, as you need to boot at full speed. No one I know of had had an I-O boot at much above that speed, but many have gotten up to 500 MHz on a K6-III+ using software changes on the FSB and the multiplier. This is worth $25 to me. 12-14-2000 14:08:22

RE:i-opener version and cpu upgrades (modified 0 times) ASPguy Profile | Email no wonder my io been crashing. i used to be able to boot at 3.5x95mhz but then it started crashing and wouldn't boot after i installed the Yamaha sound drivers. Then when i uninstalled the drivers, it still had problems booting in. i can boot into safemode without any problems though. once i reset it to 3x95mhz all problems stopped. i use softFSB to increase the 95mhz to 110mhz. and it runs fine. i couldn't find that k6clk program, any ideal where it's at? what's the best jumper configuration for the amd 333 mhz afk chip? would it be 3x95mhz then jumper the 95 mhz up? Thanks. ASPguy 12-15-2000 09:35:49

RE:i-opener version and cpu upgrades (modified 0 times) msdek Profile does anyone know of ANY programs like SoftFSB that are for linux? I don't like the idea of having to install windows on my i-opener just to make it run faster (seems kind of like an oxymoron...). Anyways, would SoftFSB work on VMware or wine, or would I just be REALLY pushing it too far? Thanks 12-15-2000 14:30:10

RE:i-opener version and cpu upgrades (modified 0 times) Void Profile I've got my V4 booting the AFK at 333. Windows runs rock solid, but I can't boot with Jailbait. I believe I have it set at 5x66.6, 2.2V, with a short on the power sense resistor. 12-15-2000 16:09:18

RE:i-opener version and cpu upgrades (modified 0 times) Programmer Profile where does JB stop? 12-15-2000 20:05:15

RE:i-opener version and cpu upgrades (modified 0 times) Void Profile Programmer: Jailbait konks out at 'Testing 'HLT' Instruction' or something like that. In another thread, I read that another person saw the same thing happen with their AFK at 333MHz... after downclocking it to 266MHz (or something like that), Jailbait booted fine. I havn't had the energy to try booting at a lower clock rate (my multiplier settings are jumpered with solder and wire). 12-16-2000 01:50:20

RE:i-opener version and cpu upgrades (modified 0 times) Programmer Profile :) you're in luck... I happen to know *EXACTLY* why it fails.. there is not enough voltage going to your cpu for it to recover from a halt. bump up your voltage a tenth at a time(or increase it by the smallest amount you can) until it works.. not that many posts on this board refer to a 2.0vcore, your cpu (not a +) specifies a 2.3v core 12-16-2000 19:58:52

RE:i-opener version and cpu upgrades (modified 0 times) ASPguy Profile | Email Anyone, programmer, My 333mhz amd afk moded iopener vcore is 2.17. the heat gets as high as 68c system, 48c cpu. i have a sunon on the cpu. Anyhow, it's at 3.5x95mhz now. boots up, but it takes longer than it does at 3x95mhz. and at 3.5x95mhz it won't restart, i have to do a shutdown. otherwise it'll get the black screen. i've tried booting up at 1.98 vcore, it goes into the windows splash but get stuck there. any ideal which is the best vcore and which jumper setting (3.5x95, 3x95, 5x66mhz) is the best to choose? Much Thanks. ASPguy 12-17-2000 04:33:10

RE:i-opener version and cpu upgrades (modified 0 times) Tackhead Profile Void/Programmer: Exactly right. I was running Windoze and using a software CPU cooler - which is also based on HLT - and had exactly the same problem. (K6-III-333 running at 1.91V) Bumping the voltage a notch (2.05V) fixed it. The extra heat I got from the higher voltage was more than made up for by the cooling I got by HLTing the system while idle. As always, YMMV. Remember that the K6-III-333 is specced to 2.2V. "Undervoltaging" is just like overclocking - exploiting an engineering design margin for performance at the expense of stability. It's just that we're (usually) aiming for lower temperatures instead of higher clock speeds. And just like overclocking - some chips will cooperate, and some won't. Them's the breaks. 12-18-2000 13:53:39
