Black screen after new CPU!

[Erm]

Hello, i'm having some problems with my coputer.
I was running an i3 530 on a P7P55 LX motherboard and decided to upgrade to xeon x3440. Now the cpu isn't on the official supported list but i've seen plenty of people running the same setup, it's the same socket and it should work just fine with p55 setup.
What i did: turned off the pc, removed the cables of fan and the cpu power, took out the fan and cleaned it from the old thermalbpaste, got the old cpu out, installed the new one correctly (fits exactly) got some thermal paste on it, a tiny rice bit, installed the fan and connected all the plugs. 
I pushed power and all i got was black screen(fans speening).
I pushed the mem reset butten which did nothing and took out the little battery (cmos battery?) which also did nothing.
Please help!

Make sure the BIOS is up to date.

that chip doesnt have integrated graphics.

I have a gtx 660 connected as gpu, that shouldn't be a problem. 

I'll try updating the bios

The xeon x3440 is a server CPU. It may not work

I've seen a good amount of people running the same setup

Yep, bios update did nothing at all. There's a red light near the memok! Butten and still have completely black screen (｡╯︵╰｡)

Help? (｡╯︵╰｡)

Reseating the ram into different slots did the trick after bios update for some reason.

Now only problem left is cpu overheating, i only had 1 packet of thermal paste so i didn't changebit after swapping out cpus, i suspect that to be the reason. Temperatures are idling at 50-60 but when i throw it a little task it jumps to 70-80. I'm using the old stock cooler from i3 530

Need a better cooler and some real paste. ~$20-30 would be about what that will cost.

80 is pretty good actually, that's about the safe upper limit for long semiconductor lifespan. How many cores is it? i7 style?

It's 4 cores and 8 threads, but it's strange why it's running so high on stock clock of 2.53. I'll try to replace the thermal paste and see if that stabilizes the temperstures. I had 1 small packet of thermal paste yesterday so i didn't get the chance to replace it after swapping out the cpus for bios update. I'll get some more today and see if that fixes the problem. Otherwise it seems to be running fine, updating the bios made the memok butten turn completely red, which gave me an idea to mess around the ram and after reseating those 1 by 1 into the blue slots from the black slots did the trick and it booted.

since you're using the stock cooler, it's not a thermal paste issue. 4 hyperthreaded cores are just hot, and the stock cooler sucks unfortunately.
