XFX 5770 - Pre cold OC testing

[Sil3ntSnip3a]

I'm testing my 5770 today. Earlier I hit 1000mhz just testing my core @ 1.29~1.31v. It passed vantage test without any troubles. In my 1010mhz test it kept crashing on about frame 3k toward the end of the gt2. So I kept increasing voltages, nothing got better. Ever since the voltage increases @ 1010mhz vantage has been crashing. Even when I went back to the already successful 1000mhz @ 1.29~1.31v

As a given, it just took me 1.3v @ 990mhz to pass gt2 and gt4 in 3d03. Its being really funky. Testing 1000mhz @ 1.30v, gt2 and gt4

Edit: I forgot to mention that I've been disabling explorer.exe and setting 3d03 and vantage priority to realtime.
