3Dmark05 now 8114 with 7800GT

[t024484]

I was struggling all the time to get the maximum from my XFX7800GT.
Although auto detect came with nice high figures, Firefly Forrest and Comanche 4 did not let me cross a certain border.
Increasing the GPU voltage increased my problems, and from 1.6 Volt the board refused to run in 3D mode.

But..... I found the cause. It was the Vgpu current limiter that was adjusted so marginal, that it did not allow a setting too far off the standard setting.
That caused black screens and the CPU hanging.

With an XFX Black version, standard setting 450/1050 I am now at 567/1350
Original 3DMark05 7221
Current 3DMark05 8114

What I have done is:
Hardware Vmod of Vgpu from 1.4 to 1.6Volt
Delta geometric clock of 50 (567Mhz in 3DMark05 and 517Mhz in Coolbits)
Hardware Vmod of Vmem from 1.1 to 1.2Volt
Change the current limit for Vgpu
Zalman VF-700
Adjust the (wrong) Mem timing to the manufacturers specs

System is trouble and artifact free.
Can run for hours with ATITool. Highest temp is 74C.

I went back to all basic setting, P4EE CPU back to 3.46 and 7800GT to its basic 400/1000, and got the following score:

3DMark05 6769

So I gained in total a fantastic 20% increase in performance !!
I know it's not a WR, but it was fun.

I have 8400 without any mods...
What was the max oc you got before you did the mods?
I am not sure if its really worth the risk.
I can run 500/540/513/1135 just fine with the silencer. With the stock cooler the card started trottling as soon as temps hit 75°C.

I was on the stock cooler with my CPU at 2.9-ish.... I was hitting 8500, didnt break 50degrees

stock volts on the core, voltmod on the RAM to 2.15, 40 delta I think.

You are lucky to have an Opteron, these AMD's give you much higher scores than a P4.
To answer your question: the max oc before modding was 462/1100.
after modding 567/1350.
All my 7800GT clocks have been increased by 30%, but 3DMark05 score has increased much less than 30%. This most certainly means that my processor is the limiting factor now.
I will try a much faster P4 that will let me increase my score significantly.

What's like the WR with 7800gt? There were one guy at SMPC here in sweden who got like 9k in 3dmark05..

I had this with onlu a 2800 mhz SD3700..



Seems u had to mod mem and core to run higher...very strange...

I don't wanna trod on your bubble or whateva. But isn't the XFX already factory clocked to 450/1050?

Heres what im getting with my PNY 7800gt:


I had to do a lot of trial and error to even get this high. almost no process/services running a very dry XP. One thing that helped a lot for me is running MSconfig and disabling every thing and rebooting. also if you run 3dmark once make sure you reboot before you do a 2nd run or your score will almost always be lower. Another thing is to set 3dmark to "real time" within task manager. Also dl Process explorer, I cannot remeber the order but if you kill services in the right order you can have only 1 running and still be in an windows enviorment. My friend from work is working on a script for me that will automatically do it for you after booting up.

Why not put a shortcut to the exe in the startup folder? Or a batch run?
