Puma/Sire Posted May 28, 2006 Posted May 28, 2006 Does anyone up there pci gfx slot from 100 to 105 when using the 7900GTX? Share this post Link to post Share on other sites More sharing options...
Guest Joalaielna Posted May 29, 2006 Posted May 29, 2006 I've heard rumors that this does help with the OC but I've never seen it done. Share this post Link to post Share on other sites More sharing options...
trgl Posted May 29, 2006 Posted May 29, 2006 Yea what exactly does the pci-e frequency do in the motherboard? I up it to 105, notice no difference, up it to 110 and it wont boot so I had to clear cmos. Share this post Link to post Share on other sites More sharing options...
Thraxz Posted May 29, 2006 Posted May 29, 2006 What does a frequency do for your htt? Share this post Link to post Share on other sites More sharing options...
uneedav8 Posted May 29, 2006 Posted May 29, 2006 It wont make a difference in performance. It could cause corruption in your files though. Share this post Link to post Share on other sites More sharing options...
red930 Posted May 29, 2006 Posted May 29, 2006 Yea what exactly does the pci-e frequency do in the motherboard? I up it to 105, notice no difference, up it to 110 and it wont boot so I had to clear cmos. It just increases the rate of data transfer across the PCI-e bus. Mine works fine over 120mhz, though I run higher voltage on my chipset (~1.80 and ldt (1.5) which may affect it. No difference in overclocking for me though, I just leave it at 100. Keep in mind too that apparently increasing it can cause instability in other compoents accessing the bus..apparently SATA drives are included in that. So be warned it might really mess things up.

ViperJohn Posted May 29, 2006 Posted May 29, 2006 Does anyone up there pci gfx slot from 100 to 105 when using the 7900GTX? It isn't needed with a stock or stock OC'ed 7900GTX. Modded cards, expecially running TEC's, Phase Change, D-Ice or on LN2 running much higher cores cocks require high PCIe bus feqs to run stable. The higher the core clock the higher the PCie bus freq required. With 800Mhz cores around 110-115Mhz is needed. The boys pushing 900Mhz core on LN2 need 125-130+ on the PCIe bus freq to get through the benchmarks. Viiper Share this post Link to post Share on other sites More sharing options...
Guest caffeinejunkie Posted May 29, 2006 Posted May 29, 2006 Dfi recommends 101mhz for nvidia based cards 105mhz for ati based card I myself use between 102-105 and it actually gives me a decent ammount of added overall system stability and I get higher clocks on both core and mem Share this post Link to post Share on other sites More sharing options...

Angry_Games Posted May 29, 2006 Posted May 29, 2006 actually DFI recommends 100Mhz since the PCI-E bus also houses the LAN and the SATA controllers and pushing more than 100Mhz can cause LAN drops, hdd corruption, etc Share this post Link to post Share on other sites More sharing options...
