Sapphire HD4850 Bios Modded, Core upper Limit to 850Mhz in CCC!

[MagnumMan]

I have 4x 3870 water cooled and voltmodded to 1.675V. I pulled down a newer BIOS from Techpowerup, 010.081.001.000 and proceeded to modify it with RBE 1.14. I did touch the custom clocks page. I also selected "Method 1" from the other clock page, and RBE said I would be able to go up to 1100 GPU speed in overdrive, but my max there is 900MHz.

Also in Catalyst 8.6 I can do Quad CrossfireX, in 8.7 and 8.8 I cannot do anything more than 2-way Crossfire, with the same hardware. Anybody else having this issue?

I have attached the BIOS I am using. Any help getting themax clock up past 900 would be great. I have set some of the voltages in the clocks panel to keep the idle voltage at 1.4V and the load voltage at 1.675V with the voltmod I have on each card. I want to set the system to 1000MHz GPU and 1271MHz memory on the 4x video cards just like I was able to with the older 010.071.000.000 BIOS that was posted early this year to get past the 862MHz GPU speed limiter.
