Solve : PCI Express Version Issue ... Crysis 3 a friend wants to play on this old system?

Answer»

Friend of mine contacted me that his system is showing a black screen with new video CARD ( no picture ). He at first thought that he had bought a defective video card and so he sent it back as RMA DOA, and was given a second video card. Second video card arrived and same issue. Placing original GeForce 8400GS back in it runs fine. Knowing that the odds of 2 video cards new being bad is slim he contacted me to see what I had for suggestions. His prior older videocard a GeForce 8400GS worked fine in this old motherboard, but the newer more powerful video card would not show up on the computer, not even the POST display when checking connections to either of the DUAL Video DVI Out as well as no video out through the integrated VGA port when testing that with an older SVGA monitor. He also determined on his own that it may be that he needed a heavier power supply for the video card. So he bought a 750watt PSU which is more than plenty for his old computer and still had the same results. He also took this video card over to a friends house and plugged it into his friends system and the video card worked without any problems ( so this new video card is proven good ) and this systems power supply was only 500watts, but it was a Core i3 computer with modern motherboard.

I suggested to him that it may be an issue with the PCI Express Version of the new video card, and sure enough the new video card is PCI Express 3.0 and his motherboard given its AGE is likely just PCI Express 1.0 with the ASUS motherboard.

His system specs are:

AMD Athlon II 2.5Ghz
ASUS Motherboard (required a flash to support the newer Dual-core was originally a Athlon 64 system with PCIE 1.0 )
2GB DDR2 533Mhz
Windows XP Home SP3
120GB HDD IDE

The Video Card he got for his birthday is this one = http://www.newegg.com/Product/Product.aspx?Item=N82E16814130818 EVGA 04G-P4-2647-KR GeForce GT 640 4GB 128-bit DDR3 PCI Express 3.0 x16 HDCP Ready Video Card

On his GeForce 8400GS its a dual video out VGA/DVI and he uses the DVI port to his single monitor, so its confirmed that the display and DVI cable are good, and its a mismatch to have this PCI Express 3.0 card in the much older PCI Express 1.0 motherboard.

Even though video cards are suppose to be backwards compatible, this is not the first time I have seen a video card that was too advanced for the older motherboard and not play well, and I have seen PCIE 2.0 work fine under PCIE 1.0, but PCIE 2.1 not play well with PCIE 1.0 and this is a first that I have seen where PCIE 3.0 video card was connected to a PCIE 1.0 motherboard.

He is now asking me for a video card upgrade solution in which he can run a modern video card on his old computer which can run Crysis 3 for around $100, and I told him that I am unaware of any good modern video cards that are backwards compatible to 1.0 but that I would suggest finding one that is PCIE 2.0 and avoid PCIE 2.1 or higher cards. I also warned him that there will be a performance loss in running the card at 1.0 vs its native 2.0 speed and this may be a serious issue trying to get Crysis 3 to run without lag and poor frame rate.

My suggestion was to save the $100 for a new computer or new Motherboard/CPU/RAM which is at least PCI Express 2.1 or better and try to find a tripple or quadcore CPU used, but he urgently wants to play Crysis 3 and I am unsure if this system can play it.

Anyone have any video card suggestions or know if this system can even play Crysis 3 or not without the system acting like a slow piece of junk? I have serious doubts that it will play the game well given the age of the hardware even if the CPU meets the requirements.
PCI-E is ALMOST always backwards compatible, the only exceptions as far as I'm aware were some old cards, I think it was some early PCI-E 2.0 cards on 1.0 slots.
I'm unaware of any sub-$100 cards capable of running Crysis 3 well at all, especially with a 2.5GHz Athlon X2. Crysis 3 is quite a demanding game and he'll NEED to splash some cash unless he'll settle for low RESOLUTION and low detail settings.Quote from: Calum on August 05, 2013, 02:42:11 AM

unless he'll settle for low resolution and low detail settings.

In which case he'll have to play it for the gameplay.

And let's be honest, nobody really plays crysis for the gameplay.Quote from: BC_Programmer on August 05, 2013, 12:19:09 PM

I actually quite enjoyed Crysis for the gameplay...but I wouldn't want to play it on lowest detail settings and a low resolution, knowing that the game was capable of so much more.Quote from: Calum on August 05, 2013, 12:52:04 PM

Well what I mean is, most people don't hear the story of the game and go "wow, that sounds very compelling and worth playing" they usually play it because they heard it totally taxes their system and has some of the best graphics available today. The gameplay is reasonable of course (and certainly better than anything previous trendsetters like id Software have put out. Crysis actually has a form of a story, whereas id's "tech demos" pretty much have the story "kill everything. good luck".Hah, well yeah, that's very true, most people do just play for the graphics. I haven't played Crysis 2 or 3 yet so I can't comment on those.

Sounds like a game of the year candidate to me!Thanks for responses to this... I think I finally convinced him to save for a new computer and get by with already existing games on his current hardware. He said he is going to save the video card for a new computer since its already proven that the video card is good and for some reason his older motherboard seems to be the issue.

I told him that I'd post this here for him to get some feedback to confirm that he really needs better hardware. Sometimes in the past when it came to games and system specs I have read people running weak CPU's with good video cards and they are able to get by without any issues, but Crysis 3 even though the CPU meets the requirements is likely to lag with both cores stuck at 100% even if he did get the modern video card to work in this old system from the sounds of it.
