Problem with 7800GTX

[TheMeekon]

Hello

Got my GTX setup last night and it runs fine so i decided too install Rivatuner and push it a bit further. I upped the core from 475 too 490 and did a few benchmarks no problem. I then check the hardware monitoring tools in Rivatuner and at stock 475 core it reports the core at 510??

today i used the detetc optimal settings in coolbits and it detected 515 core so i started too benchmark which gave me artifracts so i jumped out and check Rivatuner monitor which reported the clock at 551!

Is this rivatuner messed up or is my core actually higher than it says? I am confused

XFX 7800GTX Gamers edition

thanks in advance

Ok so when i am clocking i obviously need too take this jump in core speed into consideration, very strange

Nvidia control panel and riva tuner actually say 475 in the core settings but in the real time monitoring tool in rivatuner it says core = 529 while in 3d applications. Should i be clocking this card down? Not sure whats safe for these GTXs.
