Hello, just wanted to get others result on their cpu and system temperatures when they are running the amd 333 mhz afk chips.

i can't run it at 3.5x95 mhz cause it crashes. i am running it at 3x95 mhz and it hasnt crashed once yet. but the temperature of the cpu and system worries me.

using mbprobe and having the default settings. it says the cpu is at 140 degrees Farenheit, the motherboard is at 115 farenheight.

in the bios though, it says the cpu is at 115f, and the system is at 140f.

So my first question is what are other people's temperature reading according to their mod, and what temperatures are overheating?

My next question is why would the bios temp readings be opposite from those from the program mbprobe.

has anyone been able to run the amd 333 mhz cpu at 333 mhz? have you been able to run it at 100 mhz or 95 mhz bus? are there any further cooling than what i have which is a sunon (lasagna like) fan and it's own heatsink?


much thanks for the help.

Your BIOS temperatures are correct. Fiddle with MBProbe and rename the sensors.

(MBProbe, MBMonitor, and all these other programs make assumptions as to where to look for temperature data based on their best guess as to the motherboard type. Since the IO's mobo is pretty nonstandard, sometimes they guess wrong.)

But yeah, your temperatures of CPU 46C and mobo (sensor near Q16) 60C are pretty much in the ballpark for a well-cooled system running at 300 or higher.

The one thing left to use is the software CPU coolers. CPUIdle, CPUCool, etc. can really ease the heat load on Q16 during those idle moments.

I also have the switched mbprobe read out on the mobo and cpu. I have a tenmax fan/heat sink with a heat sink on q16 attached to the fan heatsink. The correct idle temps for my iopener are cpu=36.7C and mobo=55.9C. I have the multiplyer set to 4.5 and the sys bus at 70mhz which gives me a 315mhz cpu freq. Not bad. I would like to know how to set the fsb to more than 70 in softfsb or with the dip switches i recived from apsguy. If i go high than 70 fsb in softfsb my system crashes. Looking forward to my temp postes!!

parasyte,

i guess you're also in my boat, my iopener blanks out at 3.5x95mhz. but at 3x95mhz it runs fine. hmm.. hey, does your io run fast at 4.5x66? maybe i should switch to that cause i don't think my iopener is superfast since it has the amd as well as a 128 ram chip.

i expected much faster speed.

did you do anything else for cooling other than a lasagna fan? does your fan blows our air or suck in air? my sunon fan sucks in air. i tried switching the wires but it wouldn't even turn. i have a large square cut off of theh rf shield for the sunon fan so it can pull in more air.

my ram seems to be very hot for some odd reason.

the degrees on my io currently is 59c cpu and 43c system.

ASPguy,

Im not sure what you mean by fast, but its sure a hell of a lot faster than the winchip or p166 i had in it. I can run divx movies full screen with no problem, and mp3's with visuals full screen 640x480 with great fps. Actully the fps in the winamp viz im using is reporting 12fps,but it sure is a lot faster than that. Im thinking the fps display, which looks primative, is only capable of displaying 2 characters, therefore making it 120fps, or something in that range. My roms run great too. If you think you are going to switch, let me know if im over rating the performace of my 315mhz clock speed with 70mhz bus, because i will take the time to install the other dipswitch. For now i am pleased with the performance of my io!! MY only concern is the temp read outs by mbprobe. The alarm goes off when i do anything. I had set the tolerance upto 60C on the mobo, and 45C on the CPU, and it still manages to reach both those temps. Yikes, what to do????

ASPguy....none of these fans will reverse direction if you reverse the wires. Even if they could, the air would not blow out the intake because of the way the blades are designed. If you want a cheap, easy way to provide a lot more cooling, get a small 3" desk fan.....blow it on the rear of the case. It is surprising how much it helps the cooling.....not hi-tech, but so what? Neither of my I-Openers has seen board or CPU temps over 45C.

my iopener has jumpers on the motherboard set at 3x95mhz. i would boot it into windows then run softfsb and clock it to 3x104mhz. so it's running at 315mhz without any problems.

temperature are: 62c system, and 45c cpu.

anyone know how high we can get the amd 333 mhz afk chip to? and what the jumper settings prior and after using softFSB are?

Thanks.

by the way, where can i download that other fsb overclocking program? i couldn't find it anywhere on the net.

Temperature:

I noticed when I removed the heatsink from my V1 machine that there was a pad of heat conducting material that was supposed to conduct the heat from the CPU to the heatsink. Oddly they had not peeled the plastic cover off of it and so the plastic cover was acting as an insulator. I peeled it off and then scraped the material into a higher lump so it would contact the CPU. I dont know how much difference this made, but I am sure that plastic is not a good conductor of heat.

CPU Type:

I saw an AMD 266 for sale at the computer junk store yesterday at $26. Would I see much difference from my Win Chip if I put it in?

You might have to do the amd mod to bring the voltage down from 3.3v to 2.2v for the amd chip. the winchip uses 3.3v i believe. you can read the voltage on the chip.

therefore you can't just drop in an amd 266 and run it at that.

266 aint that bad of a speed. i'm not familiar with the difference in the amd 3 and the amd 2 though. maybe someone can let you know.

you can order hte amd 333mhz afk chip from frys for 33 dollars.

ASPguy: If your box at 300 is sluggish, what are you doing that's eating up so much CPU time? A K6-III-333 *underclocked* to 200 MHz is about twice as fast in terms of real-world performance against the original WinChip. (Are you using USB peripherals?)

parasyght: Yeah, those are about the right temps for the IO. They run hot - you're turning serveral watts of power into heat in Q16 and there's nowhere to dump it but the motherboard.

Millennium_Falcon: Probably at least a doubling in speed for most applications. But you'll have to do the CPU mods first. If there's a Fry's in your area, check out the K6-III-333 at $33.

I'm not running any special programs at time i'll use the dlink usb ethernet or dlink usb videocam. but the speed is the same with or without them.

the speed doesnt' seem to be as fast as my 300 mhz k6-2 desktop. when i open the windows explorer, it takes longer than exected. i have a 128 ram chip in the iopener, versus the 64 in my desktop.

so i don't really know the iopener isn't a superspeed as the desktop.

i have a 540 meg hd, with 166meg free space.

i'm worried about the heat. cpu is at 70c and motherboard at 45c. is that like too hot? the ram chip area seems hot. i have a sunon fan on the cpu, thought that would help, but the heat is the above.

your desktop likely uses an ultra dma hard drive, while your IO is using a VERY slow (likely PIO mode 1 or 2 hard drive) put a nice fast drive in your IO and you'll likely see some HUGE improvements..

ASPguy: What Programmer said. Your hard drive is the bottleneck here.

(The second bottleneck is likely the onboard video, the slow-updating screen and the "it ain't a mega-wowzer-3D-woohoo video card" combining to make it "feel" less responsive than it really is.)

But the hard drive's the big bottleneck. No CPU is gonna solve that problem.

Granted my IO is not super fast right now but for what it is its running prity smooth. Curently I'v still got my orignal IDT 200 chip. But here is what my system is running at:
220mhz 2x110fsb, 128MB ram, 12gig udma33 hard drive 9mm thick ?? MODLE, AND ACTIVE cooling with my own style heatsynk/fan. ASPguy has see pictures of my cooling system. but as is my system runts prity DANG fast. especialy with 110fsb. pci is running at 36mhz clock speed.
agp is running at 73mhz. I have yet to have a problem with this computer, also i'v got 3 power sucking mod's installed. I'v got my mini 1" fan, serial mod, and audio mod.

Only thing i realy need right now is someone to point me to an AMD k6-3+ 450 or greater cpu. thats cheep!

the temp on my iopener worries me.

it's 68c system and 48c cpu. i'm running it at 333mhz 3.5x95mhz.

any ideal what temps would make it dangerous for the iopener and that i should shut it down? i have a sunon fan on the cpu.

at 3.5x95mhz , when i restart and reboots it gives me a blank screen. i would have to do a shutdown instead. at 3x95mhz there are no problems.

what is the best setting ? 3.5x95mhz , 3x95mhz, 5x66mhz, or 3x95mhz ?

and up to what temperatures is it safe?

thanks.

also noticed that the power brick gets hot compared to when it was used for a winchip.

now would it matter at which vcore it is as far as the temp of the power brick is concerned?

my vcore is 2.17 , i heard someone said they run it at 1.98 but am not sure. i thnk when i tried to bring it down it wouldn't start the harddrive and the display would be blank.

which vcore would be safe for the amd mod 333mhz so that the power brick won't get fried as turbo3's brick was?

EVERY cpu/motherboard/powerbrick is different.. your results WILL vary as far as lowest voltage etc, vcore indirectly affects the heat of the power brick by increasing it's load

Bit of advice about heat sink paste: Less is better. White thermal compound is made to fill in the almost microscopic scratches between parts. It works best when it is a *very* thin layer between CPU and sink. Very thin. So thin that you can see through it. Using any more traps heat and is counter productive. If there's a obvious gap between your CPU and sink I suggest you do as the overclockers do and get out the 400 grit sand paper. Place the paper, face up, on a hunk of window glass or mirror (It's flat!) and move the two parts, one at a time, over the paper untill they're uniformly flat and shine. This is called "lapping the CPU". It works. I average 8-10' cooler after this mod. As you reassemble the CPU/sink unit go easy on the paste. What you're trying for is as much metal to metal contact as you can get.

Good luck

El_Kabong has got it right. The best heat transfer is by a metal to metal contact....the thermal paste fills in the slight gaps. This is why the stock heat-sink can never be very efficient. There is NO metal contact...only a gap filled in with a pad. Some brands of paste are better...the ones based on a silver compound are the best. You do have to be careful not to get the paste on board components, because it can be conductive (electrically). When lapping, I would start with a 400grain paper, and go up to a 1200 grain in steps. You could also use a laping compound for an ultra-smooth finish. All this trouble can really mean a big difference in heat transfer.

You, now i'v been thinking and no one has addressed this, your system is running at 60c, DO you have any cooling on the q16 chip??? because the second therm. senser is located right by that chip. AND that chip can get hot with diff voltages.

i have no other cooling other than a sunon fanon the cpu and a square above the fan that is cut off of the rf shield.

i thought running it at 333mhz or in my case 3x95mhz was okay without further cooling.

i still want to figure out how i can run it at 333mhz without having problems of it not able to restart but instead having to do a shutdown. and also it taking forever to reboot if it reboots at all at 333mhz aka 3.5x95mhz.

Thanks.

No way if thats the CASE your POWER suply is OVER heating!!!!! The q16 chip is failing when you hit MAX temp!!! You need to have a heat synk on it baddly!!!! the best way to do this from what i'v hurd with out removing any thing. Is as follows:
take a piece of copper thin/straight maby 1-2mm thick, put a bend in it 90 degree so that there is a little LIP that would just tuch the BIG long metal end ofthe little chip. you want to solder to this.the rest of the copper needs to be tuching the surface of the q16 chip or SHOULD maby even have heat compound between the CHIP and little metal strip. fold it at the oposit end whre you solder but have enuff metal tuching the majorty of the q16 chip top surface, where you bend/fold it up will act like a heat synk!

Not great but effective. Though I'm prob going to REMOVE the chip from the board and put it on my own speical heat synk setup for the ultimate in COOLing and some heavy guage wire!! NO MORE THEN 4" from orignal solder points. I bet that would maby even get you OVER clocked to 350mhz :) so it sounds like you'v got a 2part problem, YOUR CPU is to hot and your q16 chip is WAY to hot :) happy moding bed time night night

i don't know about you mp3boombox. After seeing your mod, i highly doubt if anyone else can do or would do that.

no one mentioned anything about cooling anything else besides having a regular cpu fan if running an amd at 333mhz or even yet at 300mhz. where did you read that q16 needed cooling at that speed?

my iopener runs fine at 300mhz , aka 3x95mhz. but i was just concern about the power brick because it get warmer than if it was running a winchip at stock speed. i became worried from reading about turbo3 post, but then he was running the cpu at 450 mhz and more.

does anyone else know about if it affects the powerbrick running an amd 333mhz at 300mhz-333mhz with a vcore voltage ov 2.17? which vcore voltage should i use anyways? i've heard people say they've used 1.98 but i'm not sure why.

Ive been trying out motherboard monitor and softbsd on my iopener, having used them on my other computers. However, I can't seem to get the settings right. Can anyone point me in the right direction for these two programs?

There's a great discussion on a simple method for Q16 cooling with faster CPUS at
http://www.linux-hacker.net/cgi-bin/UltraBoard/UltraBoard.pl?Action=ShowPost&Board=verytech&Post=133&Idle=0&Sort=0&Order=Descend&Page=0 for V3 and
http://www.linux-hacker.net/cgi-bin/UltraBoard/UltraBoard.pl?Action=ShowPost&Board=verytech&Post=131&Idle=0&Sort=0&Order=Descend&Page=0 for V4/V5.

To summarize earlier posts, Q16 can blow from excessive heat, and so can the capacitor next to it (from Q16's heat). BadFlash has come up with
a new simple mod using one resistor to throw off excess heat before it gets to Q16. I'm trying to get a buy of the resistors going -- they're
under $2 but you have to more than one from the usual vendors.
