Running an E8400. Between 1550 and 1600 FSB, Windows 7 comes up in 800x600. It's set to 1680x1050. PCI freqs fixed at default 100MHz.
Only voltages I've changed are vCore and vTT (1.3V). Prior to setting vTT, Windows would not start at all above 1550. Now it starts, but the video mode is screwy.
The 8800GT is a factory overclocked "BFG" generic from Best Buy a couple of years ago. Never had a problem with it. Obviously, I'm hoping to upgrade the CPU without affecting the PCI circuits.
Memory freq set to "unlinked" -- supposedly it's still running at 800MHz, but perhaps not. (Corsair XMS2, factory 5-5-5-18, 4x2048 DDR2)
Can anyone recommend where I should look, when increasing speeds are affecting video mode settings? Memory? Northbridge? HT?
Thanks in advance.
