Home / I-Opener Areas / I-Opener General Posts Intel P-200 Overdrive Upgrade CPU Anyone using this Cpu on there i-Opener?

Intel P-200 Overdrive Upgrade CPU (modified 0 times) Topic I have access to an intel P-200 Overdrive upgrade "Drop in" Cpu. Did a search here and that really sucks after going through to many threads..... This Cpu has the fan intergrated into one unit powered from the socket. I realize and am considering cutting the hole in the shield and back cover centered over the cpu socket. Is there a significant performance difference from the stock winchip? 07-18-2000 18:08:50

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) cyrixone There's one hell of a performance difference, I'll say! The damned integrated fan won't spin and it puts the CPU in a low-speed mode so it won't burn itself out. 07-18-2000 22:16:54

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) Overdrive Sorry but the overdrive CPU is socket 8. Dumbass. 07-18-2000 22:54:45

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) Hmmmm Uhhh, Overdrive you are very very wrong...You might want to find someone to help you remove your foot from your mouth.... Next time you post accurate information would be appreciated! http://www.intel.com/overdrive/podpmt/index.htm?iid=prodinfo+proc12&#Upgrade1 The 200Mhz intel overdrive drop in is specifically designed for most socket 7 systems. 07-19-2000 00:51:34

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) ____________________ Configure original cpu settings on the i-Opener down to 166Mhz and it may work! 07-19-2000 00:57:06

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) cyrixone Before you go cutting a hole in your I-Opener's case, test the Overdrive out. It is VERY common on VIA boards for the pin that is used to supply power to the Overdrive's fan to NOT BE CONNECTED. Due to the protection circuitry the Overdrive has, if the fan won't spin the chip goes into a VERY SLOW mode so that it won't burn itself out. Even if you could somehow "trick" the CPU into thinking the fan IS spining, the voltage conversion module on top of the chip would get in the way of mounting a "normal" heatsink or Tennmax fan. 07-19-2000 01:05:47

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) Opener General You may want to try an evergreen 333 0r 400mhz drop in since you are going to cut a hole in the case anyway...Will require external power supply for cpu. +12v and +5v. Frankenstein post around here somewhere... 07-19-2000 01:08:47

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) milhouse Profile Hold on Now!! All you need to do to get these nice processors humming is to tap +5v for the fan. If you look down at the top of the fan with the pin key (on the underside of the processor)to the lower left, there are three pins on the fan module that make contact with the cpu on the upper left hand corner of the processor WHEW! What a run on... Add a wire to the leftmost path and solder to the +5v on cn12 and VIOLA! She spins up like a baby. Hey,a picture is worth a thousand words, yes? Just look here I used conductive epoxy to attach the wire. Good luck and have fun! 07-20-2000 18:52:32

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) milhouse Profile Anyone else try these? 07-21-2000 19:46:34

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) goober Profile Yeah but what is the performance gain? IMHO, if you're going to cut a hole in the unit, it should be for a substantial gain. 07-22-2000 00:25:39

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) interweb Profile | Email Hi there I'm glad to see that you guys figured out how to get the overdrive fan to spin and thus out of the slow cpu mode. By the way, I believe Cyrix1 got the overdrive chip from us. I know it is not allowed to post ads here, so just let me say that if you are having trouble find a P200MMX overdrive, I do have them for sale just email me or go to www.interwb.com. Just trying to help those folks here who are looking for them. Oh well hope this doesn't upset anyone. Thanks. 08-17-2000 14:10:02

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) milhouse Profile Yep, I got mine from George at Interwb. Quite happy with them. 08-23-2000 15:53:01

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) interweb Profile | Email Hey millhouse can you email me at gcw@interwb.com I need you to clarify exactly which pin is the +5V contact pad out of the three pads. I don't want to get the wrong info!! Regards George 08-30-2000 09:10:56

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) Barak Profile A working OD 200 MMX would not work for me. Digging around in Intel tech specs, the OD chip expects a core voltage of 3.3v, which is what the older IOpeners provide. The newer units (V4 and later?) which have the SW4 for setting core voltage, can only go to 2.8, so the OD will not work with them. -B 07-12-2001 10:19:03

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) Linuxguru Profile | Email The Rise MP-6 (found on V4/V5) is significantly faster than the P200 MMX Overdrive CPU, so there's no point in "downgrading" a V4/V5 by trying to plug in a P200 MMX OD. The performance gain over the WinChip in the earlier V1/V2/V3 units is marginal. Why would anybody want to attempt this kind of nonsense when there is an inexpensive and straightforward upgrade route to 450 MHz using the AMD K6-III+/450, which blows away the P200MMX, even at 200 MHz? 07-12-2001 11:51:10

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) RIPDOTCOM Profile A P-200MMX is about 25% faster clock for clock than the Winchip. You will not see much of an improvement in any integer applications (office apps, internet and basic windows use) but video, audio, games, and any floating point intensive operations will spped up dramatically. 07-12-2001 12:59:01

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) ckbone Profile Plenty of reasons to use a P200-MMX.....cheap, easy to find, a 100% drop-in upgrade.....safe, no soldering, no whining because you won't smoke your board. Hell, if you dont like it, get the AMD chip and test your soldering skills. Mine works just fine..... 07-12-2001 14:18:43

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) oldman Profile | Email the rise cpu may be faster than a p-200MMX, but the sound drivers for the yamaha chip need the MMX to work in Windows. if you are not running Windows, this is not important oldman 07-12-2001 18:39:41

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) ckbone Profile I'm curious...Where does this idea that a RISE chip is "faster" than a Pentium200-mmx come from? I have both chips...Benchmarking on the same V4 I-Opener always gives the Pentium a higher score (at least 10%). Realworld usage shows me the Pentium is faster. FWIW...The Pentium is a drop-in replacement for any I-Opener that uses a RISE chip...no changes are necessary, switch settings are the same as the RISE. 07-13-2001 03:17:07

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) RIPDOTCOM Profile I will probably just drop a winchip-2 in my iopener due to the higher clock speed "233MHz" and It will allow for MMX and 3Dnow! technology. Does the Iopener video card support any hardware 3d? if so, the 3dnow instructions will help out at around 10-15% in directX http://webstore.evergreennow.com/acatalog/Evergreen_WebStore_Pentium_Upgrades_4.html evergreen sells them for $59.00 but I have seen them for $20 before. 07-13-2001 07:37:03

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) Linuxguru Profile | Email OK, I'll apologize for ruffling some feathers. The P200 MMX is comparable to the Rise MP-6, clock-for-clock. The link to the original discussion on this issue, with benchmarks from Turbo3: http://www.linux-hacker.net/cgi-bin/UltraBoard/UltraBoard.pl?Action=ShowPost&Board=technical&Post=1714 For V1/V2/V3 (Socket 5 single-plane configuration), the P200 MMX OD or the WinChip2 are certainly worth considering as a solderless upgrade to the WinChip, and both are significantly quicker. However, I'll stay with my position that they're not really worthwhile upgrades if you're willing to perform the split-plane and Vcore mods, now that faster choices are readily available. For V4/V5 (split-plane Socket 7 configuration), there's really no significant gain to be had from the P200 MMX over the Rise. 07-13-2001 14:43:12

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) ckbone Profile As with everything in life, you cannot believe everything you read or hear off this BBS. I have a habit of trying to benchmark every component I use in every computer I have....this includes three I-Openers of various flavors. After I got a Pentium200-mmx, I did exactly that....which proved to me anyway the pentium was faster than the RISE chip, Turbo3's results not-withstanding. I suspect various differences in OS configuration give slightly varying results during benchmarking. Whatever... Trying to clear up a few things here....I do not think you can drop a standard Pentium200-mmx into an I-Opener that had a Winchip, or a Winchip2 (without soldering stuff). I am not familiar with a Pentium "overdrive". Perhaps it's different. If your board had a RISE chip, the pentium goes right in. If you want the maximum performance without any soldering, a Turbochip400 (amd K62-400) drops right in....although it does require a separate power supply. This setup will work on any I-Opener. One of mine is setup with this chip....it's fast, but not as fast as the Turbo3 mods or the Badflash mods that use a K6 II/III of various sorts. As far as there being no "significant" gains using a Pentium over a RISE...I think a 10% gain is significant, considering the relative low power of this computer..... 07-13-2001 17:17:34

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) Linuxguru Profile | Email My understanding is that the P200 MMX OD is a single-voltage 3.3v (Socket 5) upgrade CPU, with integrated fan. The original P200 MMX is a dual-voltage (Socket 7) CPU. Their cores are probably identical in other respects. I guess that the P200 MMX OD is a drop-in upgrade for the WinChip 200 on V1/V2/V3, and should be better than the WinChip2, but about the same the Rise MP-6, clock-for-clock. Note that if you have multiple versions of the I-Opener, you can often get a Rise MP-6 for free when you upgrade a V4/V5 with the AMD K6-III/II+/III+. The MP-6 can then be used to upgrade a V1/V2/V3 after doing the split-plane and Vcore mods. This would pretty much eliminate the need to buy an additional upgrade CPU for the V1/V2/V3. What I'm trying to convey is that there's no economic rationale for the P200 MMX OD over the other available options. However, if you get it for free, it's probably a good upgrade choice for the V1/V2/V3. 07-13-2001 18:11:00

RE:Intel P-200 Overdrive Upgrade CPU (modified 0 times) Ragnar Profile Gang, I have a spare Rise mp6 and a couple sticks of 32mb ram, if anyone needs these.:-> 07-24-2001 09:55:31
