Tbird 800 @ 934 is that the highest i can go?

[Newguy123]

Hello

I have a Tbird 800mhz running at 934mhz. My motherboard is a Asus A7V. I have my Vcore set at 1.75. Multiplyer is at 8.5x. FSB is at 110. I have tryed to set Multiplyers to 9.0 but it will not boot it justs hangs. I then put up Vcore to 1.85 and get the same results it just hangs at 9.0 multiplyer setting. I am cooling with a Alpha Pal 6035 and a comair fan. My temps are 48C and been running all day. Also playing Motocross madness 2 it gets up to 50C 52C. Is there any way i can get my Tbird 800 to 1000mhz?

Thanks for any advice

[AZZKICKER]

ok your temps are high

what kind of cooler ou have
and case flow?

also you need to clean the pencile off the bridges and go to the auto parts store and get a rear window defroster repair kit and use the conductive paint in it to connect the L!s

i used to couldnt get any multiplyer that had the .5 on it

as in 5.5 6.5 7.5 8.5 9.5 ect..

but when i did it with the conductive paint i went to the10.5 from 9.5

and all multiplyers worked

now go this blue core 950 @ 1311 mhz 2.21 volts

[Newguy123]

I am using a Comair fan that came with my Alpha Pal 6035.

I have 3 case fans in there now. One in the front that is sucking in air. 2 in the back that is blowing the air out. Any suggestions on how i can lower the temp. should i switch any of my case fans around to blow air in or out of the case?

When you mean connect all the L!s as in L1 - L7 connect them all. or just the L1.

With the rear window defroster repair kit just use the conductive paint. Is there any special brand i should buy? or just anything will do?

And does the rear window defroster repair kit conductive paint remove from your CPU if you dont want it on there anymore.? or how could you take it off out of the bridges you connected with it? Can you even take it off. Like say if i mess up putting it on how can i remove the Conductive paint if and start over.?

was your old CPU a blue core?? How can i tell if my CPU is a blue core or not?

Thanks

[AZZKICKER]

my 850 is a green core

also cut a hole in the side of the case and put a fan in it blowing in right aboove the cpu

only connect the L1's

and yes the conductive paint will come off

scraped it off mine with the tip of my pocket knife

[Newguy123]

AzzKicker,

You know how you said you couldnt get any of the .5 like the 5.5 6.5 7.5 till you did the rear window defroster repair kit and use the conductive paint to connect the L1.

I can get 8.5 using the Pencil trick. But i cannot get 9.0. or 9.5 or 10.0.??

Will the Conductive Paint help this out?

[AZZKICKER]

i would think it would with 1.85 volts
also you need some more cooling before you go higher though

[Newguy123]

Azzkicker,

So your saying after i get better cooling i should do the Voltage mod to my Asus A7V so i can get more Vcore. and then raise it to 1.90Vcore or 1.95vcore then i would be able to run at 9.0 Multiplyer?

And how can i tell if i have a Blue core or Green core Tbird ?

[AZZKICKER]

just look at it
if it has a green/purple tone then its a green core
if it has a blue/purple core then is a copper chip

[Newguy123]

If you do the vcore mod for the asus a7v then can you start the computer at 1.55vcore but that would really be at 1.99vcore because of the mod?

CPU Core Voltage| CPU Core Voltage after Mod
1,55 Volt Normal | 1,95 Volt After mod

Can i start the computer running a Tbird at 1.55 or does it have to be minimum of 1.7Vcor before the mod, but with the mod that would really be 2.11Vcore?

Thanks for any advice

[proze]

have a look over at tom's hardware. they have a great article about the voltage mod for the a7v with some really good pics. i wouldn't attempt it unless your soldering skills are sharp.

also, think a bit before you do it. if you want to have high voltages, you will most likely need exotic cooling of some sort unless you live in a fridge. these amd chips run very hot if you don't have adequate cooling.

[Newguy123]

i have a good friend that has great soldering skills.

I got all the pictures of how to do it. The only thing is that i dont have the Very best cooling.

And i still had a question that never really gets answered. When you first start up the AMD Tbird Defult Vcore is at 1.70 and that is the lowest it will boot off right?? So if you do the Vcore mod to the A7V then the 1.70vcore will change to 2.11. Now my question is will the computer start if you done the Mod to the Moterboad but want the Vcore at 1.95 and you have to set the Bios Vcore to 1.55. Will the Computer start that low?? at 1.55vcore in bios but its really at 1.95 because of the mod to the motherboard?

Thanks

[proze]

the article at tom's hardware has a table of what the corresponding voltages are before and after the mod. you're concerned with how much voltage is actually going through the processor, not how much bios thinks is going through it, so it should work fine, imho. you can always use the jumpers to set the vcore, and then bios has nothing to do with the voltage whatsoever, apart from monitoring it...

[AZZKICKER]

but a good cooler like a alpha,orfio,or a swiftec

[Rob Cork]

Like Proze says, it doesn't matter what bios thinks your voltage is - as long as it's enough in reality to give the chip the power it needs, it will run fine. One thing with those case fans - if i understand, you have two and the power supply fan exhausting out, and only one sucking in. That would give a negative case pressure, which I imagine would be worse than positive pressure - less air to transfer heat to. Reposition one of the exhaust fans to suck in over the pci cards/cpu as Azz says, that ought to knock a few degrees off, and that's a start.

I'm afraid I don't believe using the defroster repair kit is necessary. Seems like a waste of time. I'm using the pencil trick, and I have no trouble with any multiplier settings. I believe it's a matter of accuracy with the pencil, and applying enough graphite to make a solid connection.

Now, I have a a 800Mhz t-bird that had no trouble at all making it to 1ghz. Top temp measured is 49c, ballz out. Idle is around 32-33. I'm gonna venture a guess that you've got a green-core t-bird, unless you have really poor cooling.

What are you using for thermal compound?

[Newguy123]

I am pretty sure i do have a green core Tbird 800mhz. I have a Alpha Pal 6035 for cooling. 3 case fans. Going go get another one and cut a hole in the side of the case and put it right ontop of the Fan that blows on the Heatsink. I am using Thermal Grease.

My temps are 46C at 1.80vcor.

Torch,
What Kind of Tbird 800 do you have? The blue or the green? What are your settings Vcore? FSB? what kind of Motherboard are you using?
What are your temps?

Thanks

Hey

Well i was messing the multiplyers Vcore 2.03 then i tryed to get my Tbird 800 to 850 with 8.5x multiplyer, did it and boot just great. Then i tryed 9.0x Multiplyer i booted and nothing happens system just hangs and then does strange sounds from the speaker. Then i decided to go for 9.5x multiplyer same thing system hangs and it just does strange sounds from the speaker. Well i decieded to go for a cool 1ghz 10.0x multiplyer boot the computer and Guess what it boots just fine in windows now at 1ghz.

Why is it that i cannot get 900mhz or 950mhz but i can get 1ghz??

Thanks for all the advice

I think the reason you can't go higher is because your FSB is to high. Try leaving you FSB at 100 and kick up the voltage and multiplier till you can't go any further. Then turn down the multiplier by .5 and this kick up your FSB 1mhz at a time till you can't go any further. THEN kick up the I/O voltage (becareful) and try to up your FSB some more, keep working it till you get all you can and watch those temps. i think you get the idea i'm trying for. If anyone has any more input please let us know.
