Overclocking/data-corruption

[xSnowblindx]

I read in the FAQ section of the Overclocking Guide by UberL33tJarad here on the forums that overclocking can cause some corruption of data. I recently RMAed HDD with 100% failure on the sectors. It was a real suprise to me that every sector came up bad. I really have no evidence of what did it, but the computer was my first overclock on an unlocked Athlon XP (2800 @ 210x11) with my Corsair XMS overclocked to 210mhz.

Anyways, I'm just curious if it could have been due to a bad overclock or something. Also, should I be weary to overclock it again on the replacement hard drive?

Thanks.

Check the fourth post down in this thread, i explained the best logical way to OC with a motherboard that does not have PCI or AGP locks, hope this helps.

I must say that i find it a bit odd that all sectors were corrupt on the HDD. I would say that when you receive you new HDD, just install the plain OS and OC software, then find the max stable OC on the basic install. If you corrupt your install again when testing you can just quickly get another working OS backup. Once you have found the sweet spot for your OC you can carry on and install your proposed OS that you intend to work on without worry of any corruption.

EDIT: when you say unlocked do you mean the processor or the mobo PCI locks etc, i think that i may have miss read you!?

I think its the memory that causes the data corruption. From what I understand, overclocked CPUs will not have a huge affect on bad data.

I meant the processor is unlocked

BUMP

I've heard stuff about PCI and AGP clocks... does this apply to my motherboard and my Athlon XP, or is this just something from new generations?

Is it possible that my data corruption could be because of that? If so, what should I know about PCI and AGP clocks? How do they correspond to overclocking the CPU?

Thanks.

The ASUS board has PCI and AGP locks in the bios. Not sure about SATA though. You didn't say which drive got corrupted, but usually bad sectors isn't the same thing as corrupted data.

edit: I mean if you corrupted the data you could just reformat the drive. If bad sectors the drive would format to no/ hardly any space.

It was my SATA hard drive.

What are PCI and AGP locks?

If not the overclock, any ideas what could have caused all the bad sectors on my hard drive?

The locks keep the PCI @ 33, and the AGP @ 66 no matter what FSB (overclocking) is at. Did you try to reformat the SATA after the problems? I just remember lots of people corrupting SATA drives when the NF2 chipsets came out. Check the bios to see if this board has a lock for SATA, it might, it has just about everything but the kitchen sink. I have one, but don't have any SATA drives so I wasn't looking for it.

It looks as though I can change the AGP frequency, but I have no control over PCI or SATA frequencies.

Are there any precautions I should have in overclocking (for the sake of having locked frequencies for PCI and SATA)? Like don't go over an FSB of 200Mhz, etc.? What should I do with the AGP frequency when I overclock?

 

[bwnv]

In the bios I believe you set the PCI for 33.33 and just below is the setting for AGP which would be 66.66 Not sure, but you should be ok on the SATA bus if you stay 200 or below on the FSB. Try adding the motherboard model to the topic, a heck of alot of these boards are owned by the good folks here. I'm sure someone else could give you better advice for the SATA problems. (edit "some concerns" and add model #)
