Hi guys, anyone here have experience with overvolting and overclocking their MSI R7770 Power Edition GPU (Factory overclock to 1100 core and 1125 memory)?
It is this one http://my.msi.com/product/vga/R7770-Power-...on-1GD5-OC.html I am new to graphics card overclocking. Currently managed to OC it to 1130 core clock and 1185 memory clock, without overvolting as I have no idea how much voltage to add. Stress test by FurMark. Also in msi afterburner (updated to the latest version), the maximum core voltage is set to the stock voltage at 1200mV. Is there any way I can change that? Cheers.  |

QUOTE(wongtheboy92 @ Apr 12 2013, 11:01 PM) I see. After restart your PC, does the overclock settings remain? hmm I just realized the settings revert back to stock settings after I restart pc. Is there any way to overcome this? |

QUOTE(WiLeKiyO @ Apr 12 2013, 11:19 PM) I am using the build-in Overclock from catalyst and I manage to overclock my HD7850 from 860MHz to 1050MHz WITHOUT TOUCHING the voltage. I gain an average of 7-10FPS. yea no difference from 1100 to 1130. But without overvolting I can't even exceed 1170 without instabilities even in need for speed most wanted.I doubt that you barely notice the performance from 1100MHz to 1130MHz. Try to push to its limit before increase the voltage, increasing voltage means you are taking risk of damaging your card. Currently I managed to overvolt from 1.2V to 1.3V using Trixx and managed to overclock to 1230MHz and its stable. Only problem is that I need to enter trixx manually each time I restart my pc in order to load the saved profile. Dunno whether is there any method for it to load the overclock automatically lol. |
