If you get one beep that repeats, it means that there is a problem with the RAM.
The RAM might be physically damaged, or is not within specifications, or not installed.
I would go with the last one.
Keep in mind that it's very easy to miss getting your RAM sticks properly seated. It can take a fairly firm push.
Reseat your RAM several times. Try one stick in one slot only. If you get a good boot, add the second stick.
If you get a good boot with both sticks, you're good!
If not, swap the sticks around, still with only the one slot, then try the boot again.
Also, the MBPros that use the PC3-8500 RAM can be quite finicky about working with RAM that is slightly out of specs.

You will soon find out which sticks work, in which slots.
Of course, you should double check with the OLD memory, too.
If you can't get either new stick to work, what exact memory did you get?

(curious - what exactly is a "mechiobnew"? :D )

I hear you. My 67 year old eyes don't always cooperate, either. :D
It's pretty easy to strip out those tiny screws on the bottom, too, so take your time...
When you open it, the time spent discovering how to seat the RAM properly, will probably be your best choice, and likely will get you to a good fix.
