Doom3/Far Cry sticking when u turn fast???

Yeah, i'm on 512 right now but my friend has a gig and there is a really big difference in those games. The smaller games you wont see any difference though.

Or add another 256mb to make 768mb. That will help a lot also for a little less cost.

I experienced that as well. I had 512MB of really high FSB ram (240, not super high, but high) @ 11-2-2-3. A gig @ 11-3-3-3 230FSB is much, much faster.

welcome to the forum and yeah CPU and RAM play a lot of differences in Farcry and Doom 3.

Yep, 512 MB ram ain't gonna cut it anymore with games like Far Cry and Doom3. I confirmed this also with my RDRAM board going from 512 to 1 GB. The problem mimics the 5-10 sec freeze problem lots of guys are getting with the Nvidia 6800 cards, but the low amount of ram compounds it. If you ask me, Doom3 could use more physical ram than 1 GB. The problem is the game was coded to load levels everytime you open a door or step out of an elevator or look around. That requires memory.

As I got a spare pair of Buffalo -5B C sticks I am seriously thinking of running 2 GB ram in my gaming rig. Since you can't overclock as high with 4 sticks (you also lose PAT unfortunately), the way to go is get a 3.2-3.4C and run low fsb, <250 at 1:1. It's possible to run 2 GB at decent timings this way. 2 GB of Buffalo should be able to do 240, 1:1, 3-2-3-5/3-2-2-5 at low voltage. On a 3.2C, that's around 3.84 gig. The massive unbuffered bandwidth of four DS sticks on an 865/875P board might make up for the loss of PAT, and hell, the Abit 865P boards do well without it anyway.

For a lot of AMD guys running high fsb with 2x256 MB, there go your overclocks. And on the A64 boards supposedly running 300 fsb with a single stick of 512, well, not sure the FX CPU can make up for that. My experience is the lack of physical ram will affect gameplay in Far Cry and Doom3 regardless of GPU overclock or how big a CPU you have or how fast CAS timings you are running.

Keep in mind I've been running an 6800 Ultra and X800XT PE the last couple of weeks, and I still saw the problem .

yes, i was afraid of that. but its isnt reasonable to expect 512 to do the job anymore. i even get freezes sometimes with diablo 2 as the cpu dips into the harddrive (i guess) cause the 512 is all used up.

I never played with 4-512 sticks ram before, and I heard of the massive unbuffered bandwidth you can get, so I'm gonna give it a try. Eva has tried this and has recommended boards. Can't overclock anywhere near as well as 2x512 though.

I might set up one gaming rig for Far Cry and Doom3, with the 2 GB ram and my 3.4C running an easy 230 fsb or 3.91 gig. The CPU will do up to 236 so I'll take what I can get from the ram. For all the other games, 1 GB of ram in the motherboard and 256 MB on the video card is OK for gaming at 1600x1200x32.

I can imagine how Doom3 will run on 2 GB ram. Man, I'm driveling .

Keep in mind that BH-5 running only 225, 1:1, 2-2-2-5 and Sr-Enh-A-D-D on an Abit 865P board will generate 3550 unbuffered bandwidth - on the 800 strap no less.

Me glad I stockpiled those seven 512 MB XMS3500 sticks .

Wierd but on FryCry I took care of most of the freez by downclocking and/or relaxing the mem timings.

At 1600x1200, Far Cry is a *****cat compared to Doom3, with 1 GB ram. If you are mainly into this game, wait for an X800XT PE. Running the Far Cry 1.3 bench at 1600x1200x32, ultra details, 4xFSAA, 16xAniso, I get 22 fps on the 6800 Ultra. On the ATI I get 32 fps, but it seems much faster.

Even with 1 GB ram in Doom3, I still get a slight stutter when opening doors. Dropping resolution the problem is still there, and it's not like I have slow video cards. The rig is a 2.40C at 294 fsb, 5:4, 2-3-3-6 with PQI TCCD, partial PAT.

I hope this John Carmack game is not a sign of things to come. Does it say on the box a minimum of 1 GB ram is required? It should have but they didn't as nobody would buy the game.

The difference between 512m and 1024m is like night and day, not just in gameplay but in level loading times too, too bad I played through and beat far cry and doom 3 before I got my other stick of 512 lol

I was able to run 4x512 MB sticks (surprisingly well) in my IS7-E board last night, and I tell ya, Doom3 is pretty darn smooth. Even at 1 GB I get a slight stutter opening doors, and maybe you guys notice the 5-10 second freeze when loading a saved game first time you run the game. With 2 GB there is no freeze, you can move forward from the gitgo.

I was surprised how smooth the 3DMarks are with 2 GB, particularly 3DMark2005 and 3DMark2003. Even the CPU tests in 3DMark2003 are smoothened out, although still jerky. Of course, load times are cut in half everywhere so the bench seems to be running faster than it is.

Frankly, once you've seen 2 GB, hard to go back to 1 GB. Only reason I had four sticks ram is I put in my spare pair of Buffalo. Rig is below; I was surprised how well I could run 2 GB ram, all slots filled:

IS7-E
2.40C at 236, 1:1, 3-2-3-5 at 2.8 VDIMM, or
2.40C at 286, 5:4, 3-2-3-5 @ 2.8 volts (!!!)
4x512 Buffalo PC3200 with mT -5B C chips
Asus 6800 Ultra at default clock

Even at 236 fsb (2.84 gig) with 2 GB ram, Doom3 and the 3DMarks run smoother than at 294 fsb (3.52 gig), 5:4, 2.5-2-2-5 with 1 GB of Ballistix PC4000 ram. Of course I get a lower 3DMark score with the smaller CPU, but the benches run smoother. Don't laugh at the CAS settings. In actuality, Buffalo at 3-2-3-5 is faster than Sammy TCCD at 2.5-3-3-6 .

I was surprised how well the board ran 4x512 sticks at 5:4! Hell, I think it ran higher than with two sticks ram. Unbuffered was 3400-3500 at 236, 1:1. Normally I'd need to run 2 sticks at 250 to get the same bandwidth. On an AI7 board with >2.8 VDIMM I can probably gain 10 mhz at both 1:1 and 5:4.

Doom3 is playable at 1600x1200x32, Max details, 4xFSAA, 16xAniso with 2 GB ram on the 6800 Ultra, default clock. I got 40 fps in Demo1, and 30 fps is generally considered playable. Mouse movements, mouse lag, panning, etc. was acceptable. Didn't do any tweaks to the game config files.

I just benched in 3dmark05 with my 1gig in dual memory and the cpu score seem to increase!! dont know if its by chance or the memory but WOO HOO!! cpu score went from 3366 to 3803
