I got my new Geforce GTX 550 Ti and I still cant play crysis 2 because my computer doesn't have the needed amount of RAM which make me so freakin mad!!
I really want to play crysis bad.

computer specs:
-Desktop
-AMD Athlon II X2 2.70 GHz
-4 GB RAM DDR2
-windows 7 (x64)
-Geforce GTX 550 Ti
-Beast sound system

4gb of ram it is enough for any game o.O Maybe it's because of your CPU which is quite old.

Btw... when you run Crysis 2 what happens? Any errors or messages are popping up?

I got a graphics card before this one (made my power supply blow up) and crysis ran just fine with my specs but after what happened I decided to get the geforce GTX 550 Ti and now every time I start the game like I can go through the main menu and all that it is just that when I start the playing the campaign my computer screen just goes dark and I am sure there is nothing wrong with my graphics card because when I run other game with lower graphic quality it run normal with no problems.
my new power supply is 450W so thats not the problem either.

Those could be drivers problem, if you have newest start testing going down with versions and see if there will be any changes. Also do other games also get black screen when you setup graphic on high or equivalent to high?

PS: Geforce 550 Ti need minimum 400W power unit so yea your power unit can run low on energy when you start to play game, and thats why there is black screen. Try borrow from someone something stronger like 550W unit and try with it.

..my new power supply is 400W so thats not the problem either.

When they say 'minimum 400W power supply' they are talking about having a quality unit, so long as it got good rails/ rail it should be fine.

i got XFX 850, good price, made by gamers.

I tested the driver versions and that wasn't the problem. Any thing I do that requires the graphic card to use a lot of processing speed will go to black screen and I will have to restart my computer. I looked through the requirements that the graphics card needs and my computer was good on each one except this one

-requires 2GB (4GB recommended)

I was nervous about that because I knew that crysis 2 took up a lot of memory. Thats why I am sure that it is the RAM. Sorry my power supply is 450W I forgot.

Yeah but what company make your power unit?

Umm you said you have 4gb of ram so whats the problem?

That's better for sure,

A vid game NOWADAYS, don't use RAM like it used to, it's all handled by the massive amounts of VRAM now, before it would have to revert to the RAM, now the games have Gigs worth of fast VRAM.

Your power supply is fine. The 550 Ti barely uses any power.

Why it doesn't work...not sure.

(Blue star) is the company that made my power supply.

I am planning on buying 4 more GB of RAM soon.

I'd get a SSD before more RAM, it's very over-rated, have you got a high performance CPU fan?
Many other things could help more before RAM.

Ahh so you have 2gb of DDR2 then, yeah it could be problem then. Also if you have win7 64bit you could use some DDR3 with it, but then you need change Motherboard xD

Ps. Blue star? o.O Never heard about this company :X

I don't think my graphic card has problems I think it is my RAM because 4GB DDR2 ram is probably not enough to run the card.

I have windows 7 (x64) but I have no money to spend on a whole new motherboard

DDR2, hmm..., DDR3 would be better.

yet blue star is way off brand.

ya but DDR3 cost more i don't have the money to spend.

DDR3 will (likely) not work with your system anyway. 4Gb of RAM is plenty. If you put another 4Gb in, you will run into problems with the cpu being able to cope with it.
I suspect the cheap psu to be the problem. $30 for a 450 psu means it is crap. Should never skimp on the power supply, 'cos often when it fails, it will take out other, more expensive hardware (read graphics card, processor, motherboard) with it.

I looked it up and my computer can hold up to 8GB of RAM

I had one before that went out in my computer before and it didnt damage any thing

4Gb of ram for gaming it is absolute maximum, and more ram won't give you more performance [period]
RAM don't have anything to do with graphic card and ability to run it or not [period]

If you have 2gb of ram you can buy another 2gb BUT i don't think that it is a problem since not enough Ram will give you only crappy performance in game, and for sure not a black screen.

If anything it can be your power unit fault since you have off-brand PSU, basically you are running game with good graphic on PC which have a bit weak CPU, and you are running Win7 on 2gb of DDR2 so graphic card take everything on herself during game and use more and more power, when finally there is not enough power and BAM you get black screen.

PS. In matter of performance you need 4gb of ram (in total) to have decent performance, because Win7 use 1gb+/- of Ram, and second 1gb will use game + it will use some of ram from graphic card. One way or another your system will choke under pressure, so if you ahve 2gb of ram it could be good to get another 2gb.

Definitely the PSU, who the hell even uses a 450w for gaming these days and a **** cheap brand? 550/650w minimum, get a corsair or scythe or something, then everything is good for a long time. Also specs like that with a 550Ti, bottlenecks the **** out of it.

ok I thought about it and I am going to return this cheap power source for a 600W not so cheap power source and see how it works.

Do yourself a favour and get a Corsair brand or similar.

Also I don't think you got what I was saying before. The processor has a built in IMC that interacts with the RAM. The older AMD processors have a great deal of difficulty handling more than 4Gb of RAM. So regardless that the motherboard can take it, the cpu will not.

who the hell even uses a 450w for gaming these days
My PSU is 150W and I'm playing this game fine.
