I just got my new system. Standard it gets 5306 score in 3d Mark 06.
Started over clocking the graphics card a bit using CCC optimized over clocking. Only get 4806 :eek:

I also have Ati tools. Don’t know what settings I should use.
What would be save for my system? I have read the overclocking thread
Where should I start? CPU or graphics? I read that the 5000 have problems as the multipliers is all messed up. Anybody know what multiplier I should use for the 5000+ ?

I have the following system:

Motherboard: Sapphire AM2RD580Adv
Processor: AMD AM2 5000+ CPU
Memory: 2X 1GB DDR667 Kingmax Dual-Channel Memory-modules
Harddisk: 1 x Seagate 250Gb SATA2 , 160gb Seagate IDE 133
DVD: 1 x LG DVD-Combo drives
Graphics: Sapphire Radeon Crossfire X1900XT 512mb.
Misc: 6 casefans. Silent Stream CPU water cooling kit

Found out what timings I should use for my memory:
Kingmax 667Mhz DDR2 memory settings - 3-3-3-8 - 2.3V :D

Now I just need some timings for my processor and GPU.

I found this on the web:

Basically there were three factors to the successful overclock - four if you count the updated BIOS.

Figuring out the fastest stable memory speed
Figuring out the fastest stable memory timing
Setting the HTT speed and multiplier
Getting the right Vcore
I wish the BIOS just let me choose the divisor manually, I could then better control the memory overclocking and get even better memory performance figures.

The memory frequency is determined as follows:

(HTT speed) x (cpu multiplier) / (memory divisor) = memory clock

... And the DDR2-800 memory (by definition, since it is Double Data Rate) actually uses a 400 MHz clock.

Therefore, to reach the 333 x 9 final overclocked speed, the following steps were taken:

- Set the FSB (HTT) speed to 333MHz
- Configure the HTT multipliers to 3x
- Raise HTT voltages to 1.25V
- Raise Vcore to 1.5V
- Set the memory speed to "DDR2-533"
- Set the DDR2 memory voltage to 2.2V (as specified for the modules)
- Set the memory timing to 4-4-4-12/2T (as 1T was not stable at that speed)
Now why was not 1T stable? Simple! According to CPU-Z the memory was running at DDR2-876!


The only problem is my memory is 667. What do I need to change
