I have not tested 5.5x100 yet but currently 5x105 for 525mhz is rock solid running winamp for 2 hours with FULL screen 3d effect at 640 res.

Rember all you k6 over clockers out there. Higher front side bus speeds will increase preformance more then cpu alone will. BUT the higher the FSB the hotter the q16 and the MORE power draw your going to have. This is because each chip needs a little more power preforming at the higher rates of speed.

Your system will run cooler ifyou only over clock your CPU, i.e. HIGH multi and LOW fsb. for example if it could be DONE 7.5x66 would be 500mhz.

i just love all this teadering back and forth between to little power and to much heat. Makes for any hackers paradice ;).

oh ya cpu temp at 120f
system at 134f

voltage is at 1.8v any less and i cant run the CPU bench mark tester in sandra.

well this is wierd, i cant run the cpu multi media test in sandra after 20min of running at 1.8v 5x105 BUT if i drop the voltage down to 1.69v i can run the CPU multi media test 20 times in a row with out it rebootig on me. This sounds like a power problem hum, I never tryed the lower voltages with it clocked at 5x110 for 550mhz.

my results are:
mmx 1393
fpu/3dnow 1933

these numbers are about 200 points below a p3 500 on sandra.

cpu bench mark

cpu 1229 mips
fpu 632 mflops

memory bandwith

cpu 106 mb/s
fpu 155 mb/s

any of you guys want to test this for me?? So far it seems like the higher the FSB the lower the CPU voltage i can use. every test i did at 105+ fsb speeds i was able to do using a 1.69 vcore, but using a 100mhz or slower FSB i have to use about 1.78+ vcore even on a fresh cold boot. Or things wont work correctly??? any of you guys want to try to varifiy this???

I believe this is true because there are less CPU cycles per board cycles. meaning the cpu has fewer clock cycles per cpu/board sink cycle.

as for preformance thus far my best at 500mhz is 4.5x110 for 495mhz.

i did some more changes to my IO, at the top where the plastic cover has the slots, i traced them onto the RF shield and then cut them out with a dremmel. Boy the heat poors out now.

Be interested to see a summary of your configuration and hacks to get where you are. Which CPU are you using ?

Ok, well i did post the info i have in an other thing BUT i'v kind of got a MIX of mod's, most of which are from badflash and trubo3.

for setup i'v got a 100k resister 48k resister, 500k pot .012 resister in parallel with r302, 3x .45 ohm dropping resisters in parallel.

my own heat synk/fan for the CPU not the standerd tennmax, a speical heat synk for the q16 and a number of other things i'v done. AND A LOT OF dremmeling on the RF shield to make better air flow.

for hardware i'm using a k6-3 450+ chip, 128megs off crucal memory, 12gig 9mm HD, one of my serial hacks i sell and one of my audio chiphacks that i sell.

a second fan which for RIGHT now is being powerd via an out side source. This is due to the little fact that the power draw on the standerd power brick that comes with the IO cant take the heat. I'v done some COOLING thigns to the POWER brick but that doesnt help to to much. one fan is for the CPU ONLY, the other fan sucks the HEAT out of the IO right where the majority of it is located then spits out of the io. this keeps my case farly COOL. but the heat i'm emmitting is ungoodly. I'm going to do a second part to cooling the CPU in a while. this involvs cutting off the metal cap on top of the AMD cpu. its just stuck on with epoxy and has heat compound on it on top of the CPU core. It is nothing more then a HOT box and removing it gets rid of a LOT of heat on the CPU.

when i do that and get more juice out of the power brick I should be able to run stable at 550mhz, thats 100mhz OC. but i'm also going to clock at a higher FSB. 4.5x110=550mhz

a 110mhz fsb will give you at least 25+ more points in sandra bench marks.

a good test for CPU preformance is that of this. download the final fantasy movie from www.finalfantasy.com its a MOV file or also known as quick time. Well at 500mhz i can play that movie Ok, it has some pauses here and there. At 525mhz its ok 5x105=525, at 5.5x100 the movie plays 94% ok with a few pauses here and there but no audio screw up's. at 4.5x110=550 i get NO screw up's peirod. except for one spot which always seems to have a small quick little pause. I cant run at 550mhz for more then 20minus stable. much after that with hard use it just reboots on me.

The other thing thats kind of intresting is that at higher FSB i can run my CPU at lower voltages. 110fsb 4.5x110 for 550mhz i could run my CPU at 1.7v, but at 5.5x100 for 550mhz i had to run my CPU at 1.82v to run it stable. even then it's a HEAT problem more likly thats causing it to reboot.

The second fan blowing air out right where the majority of the HEAT collects HAS realy helped a lot. You would be suprised at how much heat the second fan removes.
later on I'm going to change one of the resisters to a higher value so i can get a lower VCORE. if i can get the CPU to run at 550mhz at 1.6v I'll be a happy camper.

You know we realy need to have a LIVE chat for the IO again.

I could create a ROOM on MIRC that peopld could go to. Best part is that NO one can try to take over the room cause its on a server that is moderated meaning there are FOUNDER people who basicly own the room and if any one try's to screw with it. Well hehe the people who have room powers can get rid of them people's.

You know i think i will create a ROOM like that, it will be on DALNET


go to www.mirc.com download the software then for a SERVER your going to want to use DALNET any dalnet server

the room will be:
IOPENER

I go by the NIC _unreal_ using MIRC.

thre its done dalnet server room iopener

has any one seen any REALY flat squirl cage fans??? something that would be as low as the tennmax??? but only a squirl cage?? because this would be a more effective way to COOL the inside of the IO. sucking inair form all dirrection's and spitting it out the back. plus it would be thinner if the correct fan could be located.

If I read your question about squirrel cage fans correctly, you're looking for a flat fan that blows out the center, rather than sucking in and blowing out the sides. Don't think it's possible.....With a normal fan, you can reverse air flow by changing rotation direction, or by turning the fan over....not so with a squirrel cage type. What is your objection (other than looks perhaps) to cutting a hole in the case somewhere, mounting a fan on the outside blowing out? During some heat experiments I did, I mounted a std socket seven heat sink on the cpu(with a hole cut in the case), on the outside of the case I made a small enclosure over this hole with a small fan blowing out. This worked just fine....kept the CPU cool and exited all hot air to the outside. I never used this setup in my final design.....but I've beed considering doing so in my next I-Opener hack. If you just turn the fan over on a std fan/heatsink setup, you will get this effect. The fan sticks out the back slightly....so what?

a squirl cage fan will work in revers just fine. all it is is blades at a 90 degree rotating. they either pull air in in to the center and spit it out OR you can revers it and suck air out and force it into the middle which is then spit out or up if you will. I could use an impeller but i have yet to find one of the right size. the problem is finding a VERY small fan. if i could get one of them super thin fans that I'd have to attach in the middle this would be perfict. I'd perfer to use a flat squirl cage gan because it will suck air in where its the most abundent. But a standerd fan will make for a very small space in which it can remove the air with. and i'd perfer not to put a FAN on the outside which i have right now being power via and out side source.

also we should put some effert into getting as much juice out of the standerd IO power brick's as possable. If we could get more power with out it getting so HOT, over clocking and using extra devices on the IO would be less trouble sume. as is i'v drilled holes in the power brick just to get some air flow. just because of the hard drive and RF shield.

CK if and when i ever get the time to load my web page to some server you'd be intrested in my COOLING method. as is my cpu runs around 119f clocked at 525mhz. Thats MINUS the tin cap hack. Just no time or energy to do it.

also any one who has gotten one of my serial mod's non of you guys have ever given me any kind of a responce other then yep got it works thanks good buy? heh i'm in the dark you like dis like?? ugh.

has any one else gotten to a NICE fast pace speed???
if we could ge ta DRIVER which utlizes the 3D ablites of the video card and running at a NICE high speed video mark. this woudl be totaly ausome.

I'd love to be playing games with the IO using 3d. grantd the SCREEN IS SLOW but hay it fast enuff to game with at least for me. tipicly i do stratagy games so thers not much motion to the screen. but getting hardware working would be ausom.
