View Full Version : 6800GT stuttering? new build - I need HELP

Hi everyone, I am new to this forum and in need of help, I have been lurking here for a couple of weeks and just registered after I got my system built and figured maybe someone could help me, anyway.....after a good "beating" on my new system over the weekend, I am somewhat dissapointed in the performance with games.
If you look at my sig you can see what I have set up.
My favorite and most played game is the new FIA-GTR racing sim.

I had this game installed on my older (A7N8X Deluxe) system with an ATI-9700 Pro AIW and the game was flawless, never a hickup or stutter at all and that system had less memory, was run from a single (non raid) boot drive and I never had an issue.

Now with this new system, I am booting from SATA Raid-0, the game is installed on the other (IDE) Raid-0 array, and I get fairly severe "stuttering" in the middle of any game I play, I can be racing along and the screen appears to freeze for very brief moments then resume and then a few corners later (racing game) it will do it again, and then it seems to run fine for the rest of the game.

This is my first Nvidia based GPU, I have been an ATI guy for a long while now but I went with the EVGA 6800GT based on the HW Leaderboard reviews from PCper.com.

This is totaly unacceptable to me and I need some help figuring out what it may be. Is it the video card for sure? and how do I test that or know for certain?

I have some of the benchmarking stuff but I am really not that sure how to decipher the results, however here are some test results:

PC Mark 2004
Overall - 4241
Memory - 4931
CPU - 3823
Graphics - 6872

Sandra (lite)
Multimedia Benchmark:
Integer - 19169 it/s
Floating Point - 20169 it/s

HD Tach
SATA Raid (boot) - 118 MB/s sequential read
IDE Raid (games) - 117.7 MB/s sequential read

AquaMark
Triscore - 60,597
GFX - 8,889
CPU - 9,517

I have no idea what to think about these test results, all I know is that this new system which I built exactly 1 week ago feels faster in daily use, surfing the web, decrypting DVD's and shrinking them, printing, working in PhotoShop and other graphics apps but in the few games that I have played (FarCry, FIA-GTR, UT-2004) it does not seem to perform any better than my 2 year old system with an AGP card (9700 Pro) a gig less memory and no raid.

I am seriously considering either returning this 6800GT and getting a ATI X800 (or something like that) or selling it (eBay?) unless I can discover (with your help) that I have something configured wrong or whatever.
I am less than satisfied for sure.
Please let me know what you guys think, I am NOT overclocking this system in any way, I just want a serious game machine and a digital video workstation that will last me a couple of years, that I can upgrade to dual core when the price reaches the "reality" zone.
This is the first time that I have built a new system and felt like the preformance was just slightly better than my last system, every other build gave me the feeling of going from a Yugo to a Marinello.
any help greatly appreciated!
Thanks!

Is there a PCI-E setting that is similar to AGP Fastwrites? I just had a similar problem with my setup and that turned out to be the problem. Check around in the BIOS for something like that.

defrag you HD!

Brand new build, newly formatted HD's, new RAID-0, 1 week old,
cant really be much fragmentation there dont you think?

Ok here is the latest on this deal.

I went into the display properties settings for the 6800GT, and after reading the other threads in this forum regarding the clock frequencies of the 6800GT series GPU's I decided to use the "detect optimal settings" feature and it returned settings of 406/1.11, so I hit apply and went out and played the game.
FLAWLESS!
It was faster and smoother than I ever thought possible, and my temps reported immediately after playing the game for about an hour were :
GPU Core: 73c
Ambient : 46c

at idle like now they read:

GPU Core: 64c
Ambient: 46c

Now do I need to start thinking about the 1.4v mod reffered to HERE (http://www.nvnews.net/vbulletin/showthread.php?t=36901&page=14&pp=15) or if my system is stable with these new settings should I just go with it?
Also is 46c ambient a little too warm for this machine? I have the stock Athlon64 HSF, and 1 fan in the case (the one that came stock on the Antec P-160), I do not want a machine that howls like a 747 on take off roll but I would like to remain stable, fast and QUIET.

On another note my new Aquamark3 scores are as follows:

65,283 (total)
GFX - 9939
CPU - 9510

Is this a good thing?
Please remember I am not an overclocker by nature, and I am really newb when it comes to understanding what all of the settings and terminology mean, but I am technically inclined enough to know how to follow directions and suggestions. So please take it easy on me.
And THANKS for all the help and replies. :eek:

For comparing your AQ3 scores, check this thread:

Your temps look fine to me. I'd stick with the new "optimal settings" and wouldn't do the 1.4 volt mod.

Actually as soon as your done installing your fav apps your hard drive will be fragmented. I have a seperate "games" partition and after installing HL2 the drive was reportedly 80% fragmented and CS:S was stuttering like hell until I ran O&O 8.

After installing XP and all your programs the drive will be fragmented, it's always recommended to de-fragment your drive after you've finished installing.
