Bumping PCIE volts improves clockspeed?

[chiew]

hi guys,
i heard from one person who bought an evga 8800GTS 640mb version that they upped the PCIE volts in their mobo BIOS. They said that this helped them to overclock the 8800GTS, and said that they reached 690mhz core and 2010mhz DDR RAM. Is that true that upping the PCIE voltage via mobo BIOS will affect your ability to overclock? 690mhz seems very high...

PCI-E voltage, no, but PCI-E frequency,yes- in most circumstances. There was a thread on XS and even AT a while back about this and the general conclusion is that it can help for higher core speeds particularly on the G80 series (which when paired with a 680i and link boost operate at 125mhz anyway) but it seems that 125mhz would be as far as you'd want to push it before something *bad* happens

wow...i thought 100mhz was standard, and that most people wouldn't go past 105mhz...

bad to your 8800GTS, or bad to your mobo?

Bad for SATA HDD's as they run on the same bus as well as Lan controllers -but to be honest I have not read many threads with people causing permanent death to their components due to a high PCI-E frequency, however most people don't dare push it too much anyway . The 3dmark 06 records are done with PCI-E frequency's of 150+ but they obviously are on suicide runs with Liquid nitrogen.

ah i see. thanks for the help . what would you suggest i turn mine up to, if anything?

Bump...

I'd like info about this as well...
