Graphics cards and overclocking

[hardc0re_tid]

**please read before moving this thread**

when i was overclocking my CPU i noticed an option to change my PCIe Latency.

it is currently at 100, i should be getting the MSI 7900GTO sometime in the very near future, i will more than likely be overclocking the card.

questions:

1. if i am overclocking the card will i need to increase/decrease the timer
2. what actually does the timer do?
3. the timer is currently at 100 (is this the default)

you should be able to lock it to 100 in the bios somewhere.

it is set to 100, i changed it from Auto

from what ive read you gotta leave it on 100 otherwise on auto it will rise with ** fsb and could go pop!

100 is the safe option, many people set it to 101 if their mobo doesnt automatically lock at 100, in many situations you can push it higher without losing stability, i can set mine upto 120 on DFI ultra/7800gt and it is fine, doesnt seem to help in any way, i think it gives more bandwidth but the 7800 doesnt saturate it as it is, hence zero visible effect

sometimes helps in overclocking, on ati cards

No it won't I hope that was a sarcastic comment.

Its safe up to 120mhz.

Im on 120mhz for my X1900XTX

Know from my P5B that raising it too high causes the BIOS to not see any SATA drives that are connected.
