I do not think so..    But you can try.
I understand to split the FD amount is for in case of the prematurely withdrawal issue.

But I want to figure out why guy3328 mentioned about dangerous/attracting attention..? 
"dangerous/attracting attention if put big amount in 1 cert.."

Does it mean that this will attract attention from income tax department.... 
I guess one of the reasons is BR follows other banks current trend not to offer higher interest rates to FD depositors.
Thanks for the BR current info... 

I just placed my 12 months FD (Islamic) at 3.78% with RHB couple days ago. No gift was given to me.
This FD promo has required me to deposit a minimum RM 100 to open an Islamic saving account so that monthly
interest will pay into this Islamic saving account. I did not expect to open a saving account would need minimum RM 100,
but luckily I brought enough money in my wallet at that time.

RHB calculates FD interest based on monthly basis, for example, I have placed RM 10K FD for 12 months, RM 378 profit is printed on the FD cert. I collected FD cert within 20 minutes after submitted my banker's check.

RHB expects they will hit their target by next week.

I forgot to add:
RHB Islamic saving account does not come with a saving book. It comes with a small piece of green color
paper with one account number printed on it, and also with one blue color A4 size terms and conditions for
RHB Islamic bank.
