Twinmos winbond CH5 with P4P800?

Does any one know how well these rams work with the P4P800? I currently have these 2 sticks and am in the midst of upgrading to a P4P800. Heard about some compatibility isssues with the Abit boards. Does it happen with the Asus?

I am using 2 512MB Twinmos Winbond CH-5 sticks in my P4P800 Nondeluxe and it runs great...

Ive got em in my P4C-800 Deluxe and they work OK too
