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

[WhipperSnapper]

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 to 3 GB RAM. My question--what happens if I add the PNY RAM and use the 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 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?

I would take out the existing ram, set BIOS to default, put in the patriot, get it to boot, fire up CPU-Z or other 3rd party app, and check the SPD data for the actual model number of the memory.

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.
