RAM voltage and timings -- add RAM of unknown specs using current settings?

Right now my rig has 4 x 512mb sticks of Corsair Value RAM. I'm interested in swapping out two of those sticks for two 1 GB PNY RAM, upgrading from 2 to 3 GB RAM. What happens if I add the PNY RAM and use my current settings?

I don't know what the specs are on the PNY RAM since it came off a great deal on Craigslist (along with an Opteron 185, a premium 939 Asus SLI mobo, a monster HSF, and two other 1 GB sticks now in my wife's rig for $75).

After talking to a Corsair tech guy a couple years ago, we determined that I would need to run at these settings (otherwise Unreal Tournament 2004 would crash after a few minutes):

RAM Voltage: 2.8v
RAM Frequency: DDR 333
CAS# Latency: 2.5
Min RAS# active time: 7
RAS# to CAS# delay: 3
Row percharge Time: 3
1T/2T memory timing: 2T

Rest set to defaults/auto.

Would it be OK to add the PNY RAM and keep the same settings? What's the worst that could happen? Could I fry the RAM if the 2.8v is too high for it?

Do a google search on the part number on the PNY RAM.

I would think it should be ok at 2.8v, but I would look up the specs first to make sure.

I've searched for data on the RAM and can't find anything. I have:

2 sticks of PNY A0TQD PO127394

1 stick each of A0TQD PO127266 and PO127186

I received an email from PNY tech support. They said the specs are:

3, 4, 4, 12 2.5 volts

Thing is, I have to run the Corsair RAM at those other specs. So what would happen if I kept those specs and used the PNY RAM at those specs? I guess it couldn't hurt anything to find out.

Mixing memory can be unpredictable and the ONLY way to know for sure how it works is to install it and test it.
