A7V133 doesn boot up at 133 MHz FSB and Leadtek GeForce 2 GTS problems

[Mené]

Hi there...

I wonder if there are some tweaks (or a website about it), that would allow me to boot up my Asus AV7133 and Tbird 900 with 133 FSB.

With Bios Rev. 1004 I had problems overclocking the motherboard in Jumper Free Mode and Jumper Mode at 133 MHz FSB. At 100 Mhz, I could overclock it and have it post at 950 and 1000 (9.5 x 100 and 10 x 100), but only 950 was semi stable.

Yesterday, I noticed Asus did not have any longer Bios Rev. 1004 listed on their site ... they only had Bios Rev. 1003 and 1003a. I thought they may have discovered something wrong with the 1004 bios, so I flashed the A7V133 with 1003a bios. With this bios, I'm able to overclock with great stability in Jumper Mode to 1000 (10 x 100) at default core voltage (1.7 V), but I still can't seem to get the motherboard to boot up at 133 MHz FSB. I have even underclocked to 865 (133 x 6.5) and had no luck.

Today I have noticed Asus put Bios Rev 1004 back on their website along with 1003a. I wonder if I should flash it back to 1004.

I would love to find out if there is some sort of jumper or setting that allows 133 MHz FSB.

With this motherboard and Leadtek Winfast FeForce 2 GTS, I have also noticed some blue vertical lines in DOS, Bios Program and Win98. Sometimes I get a bunch of dots (as if it was a chain of squares with dots on its vertices). I tried an NVidia Vanta card and I didn't get this problem. After testing some settings, some of them recommended by Leadtek's FAQ suggestions, I discovered that enabling the S2K Strength setting in Chip Configuration helped, but I still get the problem. I wish Asus was more clear on the function of some of these settings. Hope this may help somebody else.

I would appreciate any suggestions,,

Did you find a solution so far or not!
Before the Leadtek card what did you
have in that mobo.. I may help you if
I know if you had a video card before
or not!? I had encountered the same problem
and I should warn you that the Leadtek is
not as good as you read in the reviews..
I believe that its memory is so fragile.

When you switch to 6.5X133MHz, did you let it boot into the windows at 6.5X100MHz first + addition voltage. Shut down and turn on the pc and then change the multipler in the bios to 133MHz.

Thanks for the reply,... you are right, as far as your suspicions. I called Leadtek and fortunately I had imediate help by tech support. Upon describing the problem the tech told me it seemed like a memory problem. He told me to take it back and have it replace or send the card to them and they would replace it for me. I was getting frustrated because I tried this card in a K7T Pro-2A mobo and got the same results. I then plugged in an NVidia Vanta and had no problem. This card was bought in retail package to be installed on a new system. When I took back the card, they replaced with a new one, packaged on a differente box that said 5.5 ns memory. When I opened the package it said the card was a GeForce2 Pro and the memory was set by default at 360 Mhz. I overclocked it a bit - to 220/380. It turned out a cheap buy for $159 + tax.

I plugged the Tbird 900 in a MSI K7T Pro-2a and tested all the multipliers using 100 MHz FSB. I discovered 4 multipliers didn't work - 6.5, 7, 7.5, 8, and these were the ones I needed, so that I could use 133 Mhz FSB. I redid the L1 bridges with silver conductive paste, until I had all the multipliers working. Then, I installed the CPU in the Asus A7V133 and it worked at 1 Giga (7.5 x 133) in Jumper Mode. I'm not that greedy, so this is fine for me, but for some reason the system still hangs once in a while when in Jumperless mode. So, I just gave up and I'm using it in Jumper Mode. So far it's working vvery stable.

Wow, A 64mb geforce 2 gts pro $ 290 for a 32mb gf2 gts $160, something went right for you for a change : )

Using Bios 1003a with no problem. I unlocked the CPU chip with the pencil trick. Set my 1GHz T-Bird to 133X7.5=1000. Have KingMax PC-150 Ram. Never changed the voltage settings & works like a charm. Boots perfect!

Read this, it will explain it all so you can use 133 FSB.

I have read that Anandtech article ... it was great.

It still doesn't explain why my system hangs once in a while when initializing in Jumperless mode. So far it has been working great at 1 Giga (7.5 x 133) on Jumper mode

I have the same problem. Wont post to 133, only 132 !
Asus A7v133 BIOS 1004 and TBird 1 Ghz. core AXIA
132*11= 1450 "POST OK"
133*7.5= 1000 "DONT POST" !!!!!!!!

Whats the problem ??
