have aopen ax6bc.want to run it at 133mhz or greater.having probs,please help!!!

[celeron550]

finally growing tired of my via boards(aopen ax63 pro)sluggish performance,i swapped in my ol ax6bc,after reading annands article about running a bx at 133+.i had given up of running my 600e at 800 on this board,because my creative tnt2 ultra apparently did not like running at 89mhz..i then read the article and discovered that my card had sidebanding enabled,and with that failed at 89mhz..according to the reviews in the article,creative tnt2 ultra work fine at 89mhz and 148(at least the one annand had did!)..ok.so i fired up the ax6bc(without reinstalling windows,just swapped boards,it seemed to go without a hitch..no conflicts or missing stuff in device manager,but i think the via drivers are still in there,maybe that might be a prob..),set the agp jumper to 2/3,disabled sidebanding with creative agp wizard,set the chip to 800(does 900 stock) in bios and away i went..got into windows,all my settings intact(thats why i didnt reinstall win 98se),went into device manager to make sure all the bx stuff was there annd via stuff gone,which it was..no problems so far..done a run through of 3dmark99,2000,final reality(my god! i didnt know what i was missing!i just wish via would get their act together!)all went without a hitch..i was happy..real speed at last!!!!! so then i went on the net and surfed awile,still no problems THEN........i went and run another round of 3dmark2000.it locked up in the first test(didnt before that)..i reset,tried again..same result..ok..i then tried 3dmark99 it completed a 20 min looping process..wtf?!? cool,i thought,i,ll try 3dm2k again..bingo it locked in the first test again!!! atthis point,i thought it might just be 3dm2k,as 3dm99 had no probs..i then tried final reality and guess what?it freakin locked too!!!now im at a loss..i have sidebanding disabled,agp forced to 2/3 and according to annands article,i should be running at 800 with my creative trouble free..it must be agp related,as the pci is running at spec.what do you guys reckon? could it be that my ultra just might be one that dont like 89 mhz??? or could it be something else? please help!!!as i would like to run at 800 on this bx board..im running my chip at 600 at the moment and it benches just a little slower than my old via at 800!!! could the problem be that i didnt reinstal windows? any info much appreciated...thanks all,

I dont know if I can be of much help, but I use the AX6BC Pro Gold, and it hated creative tnt2 Ultra...try a G400 or an Asus V6800 or V7700..they love to run high FSB..IMHO

I hope Mastertech is right.

OTOH, I have seen comments in one of these forums from one of Anand's testers to the effect that they do not recommend BX's @ 133 in their Buyer's Guides because some of their testers have themselves had problems reaching that speed with their own rigs.

It wasn't clear to me what all your components are, or whether this a recent stepping of this CPU , or if you had ever gotten this CPU stable @ 800, or just couldn't do it with the AX6BC. In any event, if I assume you know what you need to know about o'clocking, BIOS, etc., I think you should start from scratch @ 600 and start working up until it's unstable. Then start messing around to try and find what is causing the instability. It could be the board, voltage setting, CPU, RAM, video card, BIOS settings, etc., even the HDD. Tweaking the BIOS may get it a little higher, but also tell you what is limiting it.

AnandTech's article made 133 MHz look like a sure thing, but it just ain't so. Remember, your mileage may vary. As somebody here said, "they don't all do the dance." Anand probably used the latest versions of what is now a stable HW platform, while your board and maybe the CPU and other components are older. And their latest article dealing with this was to test specifically the video cards @ 89 MHz, not other components.

Hope this isn't too discouraging. Good luck.

This is true Ulysses, many things can cause instability..
