Problems since BIOS Update (NF4LD406)

[KingZer0]

Greetings,

 

to make a long story short sice i updated to the bios version mentioned above it seems that the RAM always clocks a little bit under the value it should have.

 

For example i set the HTT to 300MHz and if i adjust the RAM Divisor to 166 then the RAM should result in 250MHz but unfortunately it is only 245MHz reported by Memtest and CPU-Z

 

Is that a common issue and can you guys help me?

 

Sorry for my bad english but its not my native language.

Every Bios gives you 245.

On AMD 64 Cpu's there is no fixed Dividor.

hmm i dont know what you mean cause before i did this BIOS Update the RAM Clock was always @ 250 as it should be if u set 300MHz HTT and 5/6 (166) for the RAM.

Check your bios, it could be that Odd Divisor, disable it.

No this wont do the trick

 

Well could it be that the previous BIOS Versions incorrectly displayed the RAMClock?

Cause if my calculations are right the following should be correct:

 

2700MHz CPUClock (9x300) and if you set the RAM to 5/6 then 245 should come out of it cause u need to calculate it with the CPUSpeed not with the HTT which means

 

Wrong: 300 x (6/5) = RamClock

Right: 2700 : 11 = RamClock

 

Am i right?

Using multiplier 9 and 166.67 as index/divider has always given 11 as memory divider .

Thats 2700/11 for memory ~ 245.4 mhz

 

It's tied to multi/mem.index

E.g 10*270 gives another (2700/12).
