I am confused

[x_Threat_x]

I´ve been trying to O/C with my K7T Turbo RAID but i refuses to even post att 113fsb and above, and on 112 i need to use 1,8vcore to post. I´ve tride to remove all PCI cards but that didn´t help, i hade the same probem with my other processor on the exakt same system (just changed the proc. to se if it was a bad on). I´ve tried to disable AGP 4x, didn´t help, Sidebanding is off, DMA is on. I am running my only HDD on one of the RAID controllers, could it have anything to do with my problem? The cooling is good the Taisol Copperbase cooler doesn´t even get hot. I´ve tried to falsh BIOS didnt help. I Cant solve it, tried for about a week now, anyone got ANY idea?

what chip are u using - i tmight be locked with the L1 bridges. If so its an easy fix but we nbeed more info also what chipset does that board have. I fits the kt133 than that is ur prob tha kt133 is only rated at 100FSB and wont do much over 107, if its the kt133a then set the FSB to 133 and lower the multiplier

[x_Threat_x]

It is a KT133A mobo so its good for 133fsb, i am only trying to krank upp the fsb, it just won´t post, and i want a fsb Only clock, dont have any more thermal paste home so i can´t remove the taisol cooling, and draw the L1 bridges. i just can undersand WHAT is wrong

My friend got the same board, he had to remove a jumper on the mobo change it too 133fsb. I dunno where it is exactly but if u read in the manual u will find it.

[x_Threat_x]

k, but wont it go on 133x7,5 then?
i want it tog ho on 120x7,5 133x7,5 wont it be to much for my old 750 =)
or is there a possibilty to activate the 133 jumper and the go below 133fsb anyway?

did you friend have the same problem???

First of all, Welcome to the forums.

If you can get that motherboard to run at 133FSB, you will be better off. This is because of the PCI bus. At 100FSB, the PCI bus is running at the default of 33MHz (1/3 of the FSB), as you increase the FSB, the PCI bus speed increases proportionately, however when you reach a predetermined point with the FSB the motherboard changes the divisor to 1/4 yielding a lower PCI bus thereby bringing it closer to spec even though you're running at a much higher FSB. For example, if you were running at 123FSB this would result in a PCI bus of 41MHz (1/4 of 123=41), way over spec. But running the FSB at 133 would yield a PCI bus of 33 right on spec. Much less potential for problems with the peripherals particularly the hard drives and the nic.

I hope this helps.

Good Luck!

Thanx FRANK, havent tried if it is the HDD that is caousing all the trobules, it is connected to the RAID controller toug, is the controller efekted inte the same way as the standard IDE ports (from FSB overclocking)

[Phil]

yes it is, one quick way of seeing if the harddrive is holding you back is to change from udma to a pio mode. In this bios this is usually done in intergrated peripherals but on a raid controller it should be on the actual raid controllers bios. Try the lowest pio mode at first (pio 0 ) and if the problem goes then it is likely the drive holding you back

[x_Threat_x]

I tried to remove the HDD and the CD and o/c but it didnt help :( i just cant figure it out, any idea?

[Phil]

I much doubt it's a drive issue as ibm drives are quite tolerant of high fsb's. Did you try what I suggested to lower the multiplyer then set a higher fsb to see if it was the cpu or another component holding you back?
I have the feeling it's either the ram or board holding you back which a small increase to the vio voltage may remedy

[x_Threat_x]

It is not a IBM hdd it is a Western Digital, i will try the fsb/multiplier tip later on (when i´ve got some new ASII home at home)

[Phil]

I don't know why I though it was an ibm I must have been reading some one elses profile. I still have the feeling you have reached the limit of either your ram or board, setting a lower multiplyer and then testing higher fsb's is the best way to check for sure.
why is it you can't use a higher than 10x multiplyer?

[TranceBear]

I really don't think it is the board, these boards are made for overclocking. I would spend some time on your ram and other components and find out what is holding you back. I would try to mess with the ram settings to see if this is the culprit. The jumper that will get you 133mhz FSB is located behind the AGP port.

[x_Threat_x]

thanx, i will try to up the I/O voltage to 3,45 (from 3.3 stanard)

oops I was making posts in the wrong thread, I was on another thread on a similar subject and posted here by mistake, sorry for the confusion
