ABIT VH6

[dave]

Does anyone know of a way to get more voltage than 1.85 out of the Abit VH6? I know there was a way with the BH6 by flashing the BIOS, but it doesn't work on this board. The manual shows a screenshot of the BIOS with the voltage set to 3.50 so there must be a way. Please help! Thanks.

There is always a couple of methods with an Abit board.

1. follow my procedure here

2. Flash your BIOS using the /cc string at a high voltage in order that you can reset to having this as the base voltage.

Personally - I would use my method if you are a little sceptical about BIOS flashing since I know that my method is safe and it has been used on literally hundreds of peoples machines.

On the other hand - if you're a little sceptical about wrapping a strand of wire around the pins on your chip - you should flash the BIOS instead!!!

for some reason flashing the BIOS doesn't work on the VH6. I've tried it about 20 different ways but everytime the max voltage stays at 1.85, which isn't getting me past 100MHz FSB.

Looks like the VIDPIN extravaganza my mate!!! It's less scary than BIOS flashing.

Depending on what kinda FCPGA chips you do it on, different voltages sometimes appear due to the pins already connected under the surface.

It enables me to knock out 990Mhz by attaining 1.86v - so I'm happy.

My abit VH6 has max voltage up to 1.9v by default. Strange!!!!!!

 

[dave]

Your board probably shows 1.9 max because you're running a processor with a higher default voltage setting than mine is. The BIOS just takes the default voltage setting and allows you to add a certain percentage to it. I'll bet that your processor has a default voltage of 1.7 where mine is 1.65 which would explain the .05 variation. I just want a way to give me more room than the default plus.

I have this board on order should be here saturday for me to play with I am going to put my celeronII cCo 700 on and see if I can hit 1Ghz (viedo TnT2 U ) does anyone think this is possible and at what Voltage and FSB do you think would obtain this

 

[dave]

The 633 Celeron II is the most overclockable, but you should be able to get the 700 pretty close. I actually got a new 633 and am able to hit 1Gig with it at 1.85 volts. The multiplier on your 700 will 10.5 so at 100MHz FSB you'd be at 1050MHz. I'd try small steps....75, 83, then 100 and beyond just to see where the limit is. Make sure you have a good CPU cooler as it's gonna heat up. You probably wanna keep your voltage at least at 1.85, I'm not sure what the default voltage of the 700 is but you should be able to get to 1.85. If you can get higher it would be better. Good luck!

thanks i will keep you posted. Do you think a golden orb or just an orb will do the trick ??

Maybe Abit VH6 is not a good choice for OC. I have p3-800E and I can only go up to 992Mhz@124 with this board. At this speed, PCI bus is way too high (124/3=41.3) that my PCI devices (ex. SCSI controller) wont just work. Windows just refuses to to read my SCSI CD-ROm and DVD-Rom. Anything above 124Mhz will result in a blank screen. Maybe it's just my cpu and just want to tell you my experience. Hope you have better luck than i am .

The P3 is not the best processor for overclocking to begin with, its extra cache memory really restricts it to smaller overclocks.

A golden orb will probably work pretty well, but if I were you I'd get a Peltier setup. http://www.leufkentechnologies.com has some really awesome setups and will keep your CPU the coolest and allow for the highest overclocking.

Well get the new board today And golden orbe (for now) will try 75 fsb first as suggested at 1.85V default is 1.7. I got the 700 to post and boot to windows @ 833 with a-BH6 last night thought the voltage was set to 1.9 and FSB @ 81. SO I hope that it is true that I could hit 1002 /w 100fsb and 1.85V that would be so cool !!!

 

[burly]

Ok up and running but for some reason can not get to boot @ 100Mhz FSB so no go on 1000 Mhz do you think a bios flash will work ?? I can only boot @ 83 Mhz FSB putting Cpu @ 875 not bad but I want more Voltage is @ 1.85 no change if set to 1.9 what is really strange is that I don't have option for 90mhx FSb like I did on Bh6 doens anyone else have the 90 setting ???

 

[dave]

There is no 90 FSB setting on a BH6, but the good news is that if you set the voltage to the max and flash the BIOS it will set the current max to the default and allow you to go to a higher voltage...on the BH6. You definitely want to get a better cooler if you are going to try for 100Mhz, sometimes it can make all the difference. Check out the link in my previous post. Also make sure you have a power supply that can handle it all, I would say at leat 250W if not more. Good luck! My 633 is still running good as ever at 950MHz, it will run at 1000Mhz but I'm waiting for my CPU cooler to get here before I leave it there.

 

[burly]

I'm sorry I upgreaded to Vh6 no longer have BH6 and can not hit 100Mhz FSB I am using the following config
Abit Vh6 (newest bios)
celeron II 700 cCO
diamond viper v770 U
Right now have it set @ 83Mhz FSB 1.85V running 40Degrees c @ full load 700 @ 875
Golden Orb and two case fans

The VH6 will not increase the Vcore with the bios flashing trick. I have had to wrap the pins on several to get more voltage. See http://www.hardocp.com/articles/intel_stuff/bumpvoltage.html

for more info.

after wrapping pins still no luck I guess I will never hit 100mhz fsb *sigh* I even tried all the way up to 2.3V still nothing
