I have Amd 2600+ Mobile Barton Stepping of Iqyha and Aopen motherbrd of AK-77 600n which is a KT600 so PCI/AGP unlockable, question is how bad is this if i continue to increase fsb, will it fry my videocard or..?? what will the effects be..comments would help alot, thank you..

Welcome to the forum!

When you say the Aopen has unlockable PCI/AGP, do you mean it's unlocked (PCI/AGP frequencies increase with FSB)?

If you can monitor your PCI and AGP frequencies, you want them to not go above 38 and 72 respectively...if the PCI frequency goes above 38 (and even sometimes happens at 38) the harddrive and or cd drives can be corrupted. The AGP will not respond when it passes 72.

If its lockable, LOCK IT! You want your PCI/AGP to be at 33/66 regardless of FSB.

thanxs for the welcome, yea sorry about the mishap, i cant lock the pci/agp speeds, when i increase fsb the pci/agp go along with it,so is my biggest concern is anything going to blow or get hurt if i just up fsb with no lock on pci/agp..

Like Xavier1421 said, as long as the AGP/PCI frequencies don't go over 72/38 you should be alright. If you have a preset 200 mhz fsb option in your bios, it should set the divider to 1/6 which will set the AGP/PCI at 66/33. If it does, you should be able to hit 210-212 mhz fsb.
Usually the first thing that happens when the AGP/PCI gets too high is data corruption of the boot files. If this happens, you will probably have to reformat. At least this has been the case with me.

ill try that when i get home ill put the jumper up, thanxs again for the replies, i was just being cautious, my video card is the most expensive peice in my rig atm and want it babied more then anything, as im new i appricate the tolerance boys..i know the same oc questions can get frustrating...
I personally think harddrives run faster with a faster PCI bus speed-
some chipsets handle it better than others-
with a promise ata 100 pci raid card running striped raid a 38 mhz bus speed will out perform a 33 mhz bus speed- what does lol mean ???
-did this post help ?

ok i put my divider right up to 200 fsb and put my multi down to 10 before i did it, and also put agp fast write on and now it seems when i boot up windows it fine for about 2, 3 mins and then start to really hang, i rebooted some times tried upping cpu volts just alittle from 1.57 to 1.60 and did nothing, i tried upping memory volts from 2.6 to 2.7 nothing, i recieved two errors regarding video though..?? one was VPU error and a recovery ws made by ati, and another was a blue screen just before getting into windows saying problem with ATI2CQAG.DLL error 0X0000008e and then more errors similar, and said dumping physical memory..?? any suggestions..??

edit: i went and lowered the Fsb to 166 * 12, seems to be working fine now, but i have memory rated for 200fsb and the mobile chip is good for 200 fsb what am i doing wrong..??also i can hear the a: drive working at given points..?? like its trying to axs the disk
If you're board supports 200fsb, then you can set your mobile to 200x10 or 200x11, but the Vcore (cpu voltage) will need to be at least 1.725 or higher...ANYTIME you raise your clockspeed, whether by multi or by FSB, you will need to increase voltages.

Hangin in windows seems like a voltage issue. Overclocking is an iterative process. So be patient, and we'll get you through it

im checking the aopen site and i see that the brd can handle up to 400fsb, as i have the KT600 chipset, but i cant really be sure i do recall seeing the chipset in Cpu-z at Kt400, could this be an issue as well, would i need to increase volts to mem or leave that the same..??, man and im at work so nothing can be done until i get home but the more suggestions and comments the more it helps out, thanxs for the replies, my specs show be able to cope with the fsb..being at 200 * 10..?
I also have a 2600-m.mine tops out at 2570 stable.
How about this-shut off machine and clear Cmos with jumper,and set to 166 by 14 with 1.8 volt, fast write off,timings at default,T1 off. set cpu shutdown temp at 50 or 60 if aval. If it boots windows,check cpu temp first thing with sandra or equiv.then go for 166 by 15 with voltage maybe at 1.85 or so-(watch cpu temp)the 166 bus speed will keep pci speed at stock-also maybe set mem latancy at 3....what do you think ?

will try that, im new those settings i understand and have something i can try now, perfect as also i will try Xero reply as well, however i came accross this now,

i also found this on the fine print under Memory for my motherbrd, now going from left to right i have my mem stick on the right side thrid slot,i have 3 slots, so this means i should have it in the middle correct..?? based on what is said down below..??my mem stick is doubled side

DDR400-3200 Ram
a. Max memory size will be 2GB.
b. DIMM1 + DIMM2 by double side module.
c. One double side on DIMM1 + 2 single side on DIMM2 + DIMM3.
d. Don't suggest DIMM1 + DIMM3 use double side module because the driving on memory is unstable.

now i should mention that my ram stick is also silver and then fades to copper on top just above one of the rams at the bottom of the stick, is this something i should be concerned about

try booting with just one stick and try different slots,and maybe try to clean mem pins a little with rubbing alcohol and stick um in a couple of times to try to clean ddr slots a bit.....
I have one stick of 512 and everything is brand new so i doubt anything needs cleaning..? well i wouldnt say brand new about 2 weeks or so i mean thats still pretty new...i think it may be a matter of upping voltage...
Well i upped my volts to 1.75 for the cpu and now prime 1hr 20mins stable with 41 cpu and case 39, current fsb 202 * 10, should i keep going with 1 hr tests until computer starting hanging again and then lower fsb, and then work on multis the same way..?? also my ram timmings are still set on auto should i leave it that way..??
a 200 fsb is a good stable speed tighten the timings and watch for stability now and see if you can add .5 multiplyer at a time but it will run hotter so watch voltage and cpu temp,maybe set up a fan and blow cold air on motherboard like I do,Im running 200 by 12.5 ,1.82 volt 2 2 2 5 t1 ,41c.............................................. .........................................
Alright ive done alittle more tweaking and got it to 2.43, and only 44 load, i can get it higher but it seems im alittle stuck, i go alittle high and windows likes to hang, ive got my mem still on auto, can this be a prob and volts to cpu is 1.75, to mem its 2.7, any suggestions..??
It can start to hang because the AGP/PCI frequencies are getting too far out of sync. What are they? What is your fsb? Most people I know with the KT600 max out at 210 mhz fsb.
im about that right now on FSb currently im at 44 load with Fsb(212) and multi 11.5, which is 2.43, ive tried alittle higher and gets to windows xp screen then reboots, any ideas, i can go higher my temps are still low, well i think so
