How to get 1.05v~1.825v on the ST6

[ol' man]

Somehow I got my old ST6 going and I found that connecting vid 0,25 and 3 while covering vid1 gave me full use of all voltages through 1.825 to the lowest possible. (vid 1 is actually ripped out:9 but covering it will give the same affect. I used black nail polish so I could see where I missed some. I used a old retractable pencil and dipped the end in the nail polish and simply put the end of the pencil down over the pin sliding to the bottom but being very careful of course. Then I pulled it up and it left a fairly good coat. Doing it one or two more times seemed to cover it completely.)

This ST6 seems a bit more stable than my TUSL-2 at lower vcores. VIO is at default for this board at 3.3v.

I found if one applies a real thin layer of nail polish on a vid pin it will still fit in the hole. At the same time also though it will disable that vid pin too which is neccesary to allow full use of all the voltages I think. It essentially gives one a 1.75v default vcore. Thus you can wiretrick the vids 0, 25, and 3 together and somehow this gave me full use of all my voltages on this board.

Running prime right now and I will tell you how it goes. If this works good I may have a TUSL-2 for sale "cheap". If thise works good though one may not want it for OC'n this celery. Yeah I think abit still makes a good board. I will keep you posted.

Awesome.

I think I'm becoming increasingly willing to try and pull the IHS off... dunno that I have a razor blade though ,might have to pick one up.

How fragile is the core again? :)

[ol' man]

I may come up with good idea's but I make plenty mistakes. I got a dead 1.2GHz tualatin to prove it(DON"T USE A HACK SAW ON YOUR TUALATIN CHIP). I do like this board though right now better than the TUSL-2. I think I am going to start a thread on this cause I am the second person now that has good results it seems to hit the 1.6GHz with the ST6. Been running prime for close to an hour. I will tell you this though. One thing I almost want more than this chip to stay stable at 1.6GHz is to clean up all the crap I got all over my room from thge last week of trying to get this chip to do the 133 dance while also to put this dag blasted system back in the case. If you haven't noticed I am starting to go loopy. I mean this chip was stable for a good while on the tusl-2 then all of a sudden it took a shi# on me essentially. This ST6 is well burn't in though too by now since I have had it running since early August. Maybe after the burnin' on that TUSL-2 it took a dump. One other nice thing is I got one more notch to go with the vcore if I feel so inclined. May hit higher than 133FSB if it may.

Thats a cool method!!

Lets see what others get on the ST6 and the TUSL2..

Its plenty fragile. If you have a stubborn clip I would reccomend finding something better. You have the pal and that is a pretty good clip for this core. I found a piece of foam that is thin enough to make pseudo pads with. It is the kind of foam they put in packages when shipping stuff. The real thin stuff. I am not using it now but I found it would probably work much better than those feet the pal comes with. Just an idea.

Yeah, a shim of sometype will be required ;)... I have already removed and promptly discarded the foam pads because they didn't cut it (too high and were keeping the heatsink from making contact with the chip).

I'm close to doing this, but for now (since I'm only surfing) I have her at 1.20 with the +33 clock which seems to move just fine for everyday use (again, for now... until I get that IHS off)

The reason I've decided to do this are 45C temps and a really high voltage (1.725 on this board turns out to actually be 1.79 :eek: ).

[ol' man]

Yeah dude that is close to what I am using for my vcore. Might as well be running it at 1600MHz with that much juice.

I am starting to think that jmsandrsn had the right IDEA when he used the st6 to OC his celery to 1.6GHz. I have been running prime now for four hours. No problems what so ever. But with my luck that may change soon. You never know. I like though being able to run at 3.3v I/O and still be this stable. Very nice. Just cause the TUSL-2 has all those goodies doesn't mean it is going to be the best I guess. For that matter some of those other MOBO's like the Gigabyte and the SOYO and MSI may be good for this chip too even better than the TUSL-2 for OC'n it. I just didn't know much about them. Live and learn.

[funnyperson1]

yeah, hopefully my dadll get his BD133U and 1.2 this week so i can mess with that......

[6502kid]

Wow. You are one hardcore overclocker dude.

Nice trick.

How much are those things anyways?

Seeing how people are saying Abit is stabler than Asus.. I see it really shows.. :)

[ol' man]

The nice thing about the wire trick on the abit is that you get complete use of the vcores you know as I have said. The other nice thing about the abit is you can run a 130 x 1/4 divider too. I can't do that on the asus and also I can't get the asus to run stable at anything over 38MHz PCI. This here abit would run 43~44MHz and I haven't tested higher:D Wish I would have had this mobo going when I did my dryice/alcohol oc'n earlier when with the ASUS I hit 1870MHz. The PCI bus was maxed at 38MHz. Go figure huh. I was really hoping on hitting the 166MHz fsb mark for a 2GHz score but alas no go. Maybe next semester I will go nutz for a night again once i have this chip good and burn't in. I'll see what she'll do then.

[Yodums]

Crap your a crazy ol man!! Going for a 85% overclock!! hehe

The 1/4 divider is only for Abits? I have it to but I thought many motherboards would have it rather than just the Abits

The Wiretrick seems to be very useful once you can hit more but you can't hehe.

the Iwill is about 100 buckaroos....

[ol' man]

I should add also don't leave 4 lbs of dryice out in the cooler to simply evaporate/sublimate in the air. If you do you may wake up in the morning like me with a splitting headache:D Yeah thi sreally happend and I am sure I lost a few braincells that night.

Who says overclocking doesn't kill:D

Felt tarded for a good couple days.

Ahh pretty similar prices to the TUSL2..

[funnyperson1]

yeah, but i wont have to do a mod to get those voltages that ol' man did, also goes from 65-200mhz fsb in mhz increments, only pII board ive seen do that...

[ol' man]

If I am not mistaken my st6 will goto 255MHz fsb in 1mhz increments of couse. I would love to see a pci bus that could run at 255/4;) Though!

Think there's a 1/5 divider, isn't there?

[ol' man]

Think there's a 1/5 divider, isn't there?

Oh no, if there was I would have found it:D I had my tualatin before its untimely death do 169mhz fsb on this board. There was no 1/5 divider. If there would have been it most certinely would have increased stability at that speed. But at 1500Mhz/166fsb it was a tank at 1.6v. Hot running but still a tank. I used the retail sink on it.

[Pinky]

So I guess thos bus speeds up to 200 are worthless then, if there's no 1/5 multiplier which begs the question: "Why bus speeds that high?"

[Placid]

You need to be special to use them :)

[ol' man]

I should tell you all now I found out that it will show all the voltages from 1.05v to 1.825v but when your defualt is 1.75v I guess you can't use the lower voltages or something with out taking out the wire trick. O well this is still applicable to hit 1.825v core which is more importent than hitting 1.05v:D To some here;) Like me:)

Holy crap.. Talk about wacked FSB!

[ol' man]

I almost ordered turbo pLL form a japanese outfit and I still have their adress if anyone is interested. They would work great with a 133fsb tualatin chip to hit the 166 or 200fsb mark. Especially if one had a engineering sample. If anyone here is interested let me know. Here is the stickler they are I believ between $250 and $300:eek: I think I will stick with my celeratin.

[Placid]

$250.00?
Yatta!

I seemed to have been full o' shi# here again.

THE MOD EXPLAINED ABOVE DOES ALLOW ALL VOLTAGES BETWEEN 1.05v~1.825v.

I screwed up cause I set the FSB at 100 and vcore at default but left the pci divider at 1/4. So I thought I couldn't run this machine at that speed. My mistake, shold have ran the dividers at 1/3.

ONCE AGAIN THE ABOVE MOD DOES ALLOW YOU TO GET ALL THE VOLTAGES BETWEEN 1.05v~1.825v ON THE ST6.

Good day:)

[weoul]

Very interesting,but does this method suit for III-s?
I have Abit ST6 and Tualatin 1.13 with 512kb on die,so could I use in my case?Or it's more safe to connect vss and vid2 and simply get 1.67v?This is first question.
If your answer is yes,how could it be practically done?I mean:to set in bios "default cpu voltage",then perform your mod,return tobios and set desirable value?
OR anyhow otherwise?

Yeah I don' t think you will need more than 1.675v on that chip. You had better have good cooling with it too. If you really need the extra .025v I can show you how it is done.

[weoul]

Thanks for answerring,but I still donn't understand,can I use YOUR way to mod my proc?
