Hello.

 

In the BIOS Genie settings >Dram configuration

 

Press F7 to load optimised defaults

Then change only the CAS latency to 2.5

Save & Exit

 

What happens?

@THunDA

no unfortunatley not , had to sell my old Socket A rig to be able to buy this. Tommorow a pal of mine will lend me his Kingmax Hardcore 466 SPD 2,5-3-3-7 and we'll see i f its the board or my memory.

 

@wakeup which board revision do you have? R.AA0 R.A20 R.A30 R.AB0?

it's written on the sticker thast on the side of the second PCI-e slot.

I never got CAS 2,5 work either. Only CAS 2 seams to work with my RAM ... No biggie for me, as long as it's stable (which it is).

 

Kind regards,

Karl

I have the exact same problem and have been unable to come up with a solution. I can't post with 2.5 or 3. But I can with it set to 1 , or 1.5. Strange....
