Updating information with Credit Bureaus?

I recently paid off 1 credit account (the limit was 500 and I had used about 450 of my limit. I recently paid 400 toward my balance, leaving me with a limit of 450 currently.) My question is....I am in ahuge rush to update my credit report to skyrocket my credit score!! Would it be beneficial to write the 3 credit bureaus AND my credit card companies to ask them 2 update this information?? Has anyone ver heard of this working?
