gettin k6clk to work (modified 0 times) Ragnar Profile Gang, I am at my wit's end trying to get k6clk to work. I have what is marked as an amd k6-2+ 450 mhz processor that I got from Software and such. I have installed sw1 and sw2 and am booting at 300 mhz. I have tried different combinations of sw1 and sw2 to boot higher but no go. I have downloaded k6clk and saved it to a directory. I rewrote my autoexec.bat to load k6clkini.com on boot up. But when I run k6clwin and change the multiplier nothing happens. Could any of you have been successful at getting this to work write a step-by-step procedure, or basic how-to? I would greatly appreciate it. Thanks 06-10-2001 00:45:48

RE:gettin k6clk to work (modified 0 times) Programmer Profile what do you mean by nothing happens? what utility are you using to determine the speed of the system? 06-11-2001 06:40:48

RE:gettin k6clk to work (modified 0 times) Ragnar Profile I have the wcpu program loaded in start up and displayed in the tray at the bottom. It is a real time program. "Nothing happens is not really accurate". Once I initiated the k6clkwin command, I foolishly typed in 4.5 as the multiplier. Nothing happened immediately,wcpu reported no change in the speed but within ~20 minuite I started to get screen black outs, and a slightly elevated heat problem. Nothing severe, just motherboard monitor reporting that temps had risen for ~90F to about 115F. That not terribly high, but this particular I-opener's video chip has always been sensitive to heat. This may have occurred because I had removed Rain, because I had read that it can cause problems when using k6clk. After that, I tried to lower the multiplier but when I would check to see if the change was accepted, in dos k6clk = always reported the 4.5 multiplier setting. So I removed the k6clk program and re-installed rain and I am back to a happy camper at a reported 300 mhz with temps stable between 90F and 95F. I am thinking about using the dos k6clk application when I get up the nerve this afternoon. 06-11-2001 09:50:41

RE:gettin k6clk to work (modified 0 times) Programmer Profile sounds like it was working.. 06-12-2001 06:08:26

RE:gettin k6clk to work (modified 0 times) Ragnar Profile Yelp, it does sound that way, but wcpu did not report a change in speed. On my V1 I use softfsb to go from 200 to 225 mhz and when I do, wcup reports the change immediately. I have played with several versions of autoexec.bat and don't quite remember the one that "worked". I have all of them .bak1,.bak2.,... but there like 12 versions. Let's see if I can line these ducks up.... 06-12-2001 09:13:45

RE:gettin k6clk to work (modified 0 times) Ragnar Profile I do believe my initial problem using k6clkwin is due to an I\O mapping conflict. Usually after crashing Windows would have to do a systems registry restore. Since I don't want to get into I\O remapping I have set up my V4b I-opener to us the dos program k6clk.exe in autoexec.bat. Right now I have only k6clk.exe stored in a folder. My line in autoexec.bat is Path C:\k6clkdir\k6clk.exe. Since the default multiplier is 4.5 I have added nothing else. Though it seems that every program loads faster ( wishful thinking?.. at least I haven't crashed, yet ) Wcpu still reports a speed of 300 mhz. My question now is to any of you who are using a k6 + at higher than 300 mhz, how do you really tell, and by using what software? Thanks. 06-12-2001 16:00:55

RE:gettin k6clk to work (modified 0 times) Programmer Profile I use AMDs cpuinfo utility available from their web site. 06-13-2001 04:45:32

RE:gettin k6clk to work (modified 0 times) Ragnar Profile Gang, OK, I finally got k6clk.exe to work reliably in my V4b. Copy k6clk.exe to C: directory. Then add two lines to your autoexec.bat file. 1. Path c:\k6clk.exe. 2. k6clk X, where X is the multiplier that your processor will support. My amd k6-II+ runs rock solid at 4.5. It runs so well there that I tried a multiplier of 5. I have had mixed success at that speed. I have noticed that if I try that multiplier from a totally cold computer ( Right now I am using a 12V fan and heatsink to cool the processor. With it I haven't seen any temp over 110F. I have a seperate 5V fan used to cool the .12 dropping resistor and force air movement through out the case. Motherboard temps do not go over 95F. This is without using any cpu cooling program. ) I get the continual automatic rebooting thing. But if I set the multilplier to 5 after using the computer for a couple of hours I don't get the ghost rebooting my machine. But if I turn the computer off, let if cool, automatic rebooting reoccurs. Has anyone else seen this behavior? 06-15-2001 13:54:11

RE:gettin k6clk to work (modified 0 times) mp3boombox Profile | Email yes its a 2 part problem. first part is WAY TO MUCH HEAT. second part is a power problem. What are you using for a power supply??? dc-dc or dropping resister or NON of the above??? REGARDLESS you NEED one orthe other f you go above 300mhz no matter what!! as for a FAN a 12v fan if its not running off a seperate power supply that thing will suck more power regardlss becaues it can handle more power. you should be using a 5v fan and a DC-DC adapter. My io runs fine at 550mhz OC 100mhz temps run around 110f for CPU and less for board. i never get boot problems any more. When i had the dropping resister i often found my self with a STABLE running system BUT it didnt boot correctly. would freeze or not even turn on. bare these in mind. Also as for k6-clk program its very easy just have a line inyour autoexec.bat that says k6clk X x being the multiplyer example: k6clk 4.5 so in the autoexec.bat it is like ######### ############################ ################ k6clk 4.5 just put the k6clk program in your C:\ DIRECTORY 06-15-2001 22:53:07

RE:gettin k6clk to work (modified 0 times) Ragnar Profile Mp3boombox, Yes, I am powering the 12V fan using a second power supply. I am using the dropping resistor to solve the q16 heat problem. I quess that I will have to get a better power supply if I want a stable 500 mhz or above. And, I want to move the 12V fans power source in board and use a transistor to have it turn on and off with the rest of the system. It always seems that there's one more thing to do! :oP 06-16-2001 07:26:29

RE:gettin k6clk to work (modified 0 times) mp3boombox Profile | Email just wondering??? why are you using a 12v fan???? you can get plenty of 5v fans which will work just as well. The main problem is just setting up the IO to work nicly. The things you need to work the IO well are simple. laz fan, or custom like i have. DC-DC power adapter to save a bundle of power insteading of making heat out of it. an imod3 or waht ever hard drive mounter so that the IO doesnt have a loose connection to the drive. if you do this you can hit 500mhz easy, OR if you have GOOD cooling you can run at 550mhz easly 600mhz is realy kind of pushing the CPU a little to far if you got a k6-3 450, if you got a k6-2 500 you could prob run it at 600mhz easly BUT the IO tends to loose its USB function's at 600mhz for X amount of time, I dont know if this is a heat problem or what??? my k6-3 450 doesnt like to run at that speed for much more then 20 minets befor it reboots on me. I need to refind my cooling system a little bit. and maby find out if i need to put a super shallow heatsynk on the IO system chip. OR main input output chip which handles the AGP,ide,serial,every thing a standerd computer has onboard is run from this chip. 06-16-2001 20:36:36

RE:gettin k6clk to work (modified 0 times) Ragnar Profile Mp3boombox, I was able to pick up three surplus socket 7 heatsink/fan combos for $2 each. Using one of these alone cools the cpu down to <105F and motherboard temps < 95F. This is the max temps while running at 450~500 mhz. The 5V lasagna fan didn't begin to keep the temps where I like them to be. Having had two laptops die from heat I know what the cost of improper cooling is. I am not sure of the cost of using the dc-dc dropping method, but, to me, at least, it would cost more in money and time compared to the resistor method. My definition of hacking is getting the results I want using the materials at hand and at the least cost. Have you ever heard of Occum's rasor? To get more power to my machine, I am going to frankenweenie the old Dell laptop power supply that I saved when the laptop finally died. It provides 19V at 3.5 amps. More than enough. ( Can you tell my specialization in math is optimization theory? ) I have my second 5V fan blowing IN thru the ram door. This over pressurerizes the inside of the box and helps expel the heat generated by the hard drive and video chip out the whole I cut from the radio shield right above the hard drive. It solved my video heat related blackouts. My V4 has a mod kit mounting the hard drive and provides very little space for air movement to cool the video chip. A 5V fan alone blowing on the cpu will not cool anything but the cpu. Overclockers will actively cool everything that generates heat. By the way, since I am a mathmetician and not an engineer, on a V1 to enble split-plane voltage you use a simple two resistor voltage divider, is it not possible to use the same method to divert the unwanted voltage back to ground before it gets to q16? I apologize for the lengthing reply, but it is by exchanging our thoughts and methods that we will work out the best solutions to get the most out of this machine, more than was ever intended for it.:o) 06-16-2001 22:37:08
