Hey all,
Ive had a lockup problem while playing games for about a month or so now. I can surf all day no problem
but anytime i play games like COD:MW2 it will usually lockup. There is no set time, it could be right away
or any time during play. I have tried, New drivers/Old drivers,Fresh install of XP, I even RMA the video card.
nothing has helped. The error is reported as NV4_dsp has stopped working properly.... reboot and i have to
reboot to get back to normal. After reading alot on the net and nothing helping, i finally saw someone say try
manually setting volts to RAM. So i check my Ram makes stock volt #, 2.1v still locks up. I saw in same
thread that 1 said he had to go to 2.3v before it stopped lockups. I tried 2.3v and so far no lockup yesterday.
All my temps are @ normal CPU 40 idle 50 gaming, Video card, 65 70 gaming.
If 2.3v has stopped the lockups, would that be a sign of bad ram or something else not up to task?
system:
Intel Quad 9550 "yorkfield"
4 gig (2x2 gig) Crucial RAM
BFG Nvidia 275 GTX
XP pro
no sound card, uses USB for sound/mic

its probably the ddr2 rams. 1.9~2.1 is about the average for these (http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=crucial+ddr2&x=0&y=0), and 2.3 is a lil bit high for stock speed.
might want to try lowering ddr2 speeds and setting it to 2T, loosen timings to lower the voltages.
have you tried using memtest86+ to test for bad mem blocks? http://www.memtest.org/#downiso (http://www.memtest.org/#downiso)
.. it might be that NV4_dsp gets mapped to that same bad memory address. unlikely but possible.
-
did you try memtest? try it at stock or recemmended voltage see what happens, or try it at the 2.3. see if you get any errors.
thought id throw that out there
guess i posted at the same time, lol not trying to copy your answer

2.3v is a scary amount of voltage to throw at memory. I would run memtest and see if you have a faulty stick or more. Is your system overclocked at all? Do you have the memory settings set in the BIOS or are you letting it do it on the fly so to speak. Can you please post your motherboard and memory make and model. If your memory passes memtest then to me I would bet it is a compatibility issue between the mem and mb. Despite what some say, not all memory will work at its rated speed and specs on all motherboards.

There could be a lot of problems related to this. My guesses would be RAM as #1. However, there could be another issue at hand. May be PSU related. A few years back my computer would operate just find and dandy with no issues until I would go to play a game. Randomly, it would reboot and get a BSOD. Sometimes I'd play various games and could play for a couple hours with no problems, and sometimes it was 5 minutes. My BSOD would also display the nv4_disp.dll BSOD message as well. My first thoughts on this RMA the video card, but after talking with BFG with an actual technician (not a regular read off this screen troubleshooter) he mentioned check out my PSU. Which in turn proved to be the issue.

I was curious and googled the problem, looks like a array of possible problems. memtest first:
possible power supply as mentioned, card temp( running to hot).
-
What motherboard do you have? What USB headset are you using? Im betting therein lies the problem.

CPU: Intel Core 2 Quad Q9550 Yorkfield 2.83GHz 12MB L2 Cache LGA 775 95W Quad-Core Processor
MB: ASUS P5Q Pro Turbo LGA 775
RAM: Crucial Ballistix 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Model BL2KIT25664AA80A
PSU: Antec Signature SG-850 850W 80 PLUS BRONZE
HEADSET: Logitech
i set Ram to 4 4 4 12 which is what its suppose to be, didnt stop locks. only thing that stopped them is volts to 2.3.

Sounds like a faulty ram, either dying or not seated. Try unseating/ reseating stick(s), or remove all insert 1 at a time, see if error still occurs. Process of elimination.
Good Luck!!!

run memtest. Its easy to do if you have a way of burning an ISO to a cd/dvd. You can get it here http://www.memtest.org/ (http://www.memtest.org/) scroll to the download section and get what you need.
