Ok I just built my news system about a month and a half ago. Was getting the nvlddmkm error bsod had to reboot pc. I believe the fix for that was nvidia reverting back to an earlier driver. Im a gamer so im playing L4D2 and the sceen stutters hangs for maybe 5 seconds then snaps out of it everything is fine. 10 minutes later screen freezes the sounds stuttering for about 5 seconds pc then reboots on its own this has happend 10 times since Ive built the pc. My cpu temp never gets above 50 And my video card never gets over 60. Ive run a memory test on my pc every thing is fine. Now im playing Borderlands and the same thing happens. So now I have a pc problem as the issue happens on 2 different games in the same way. BUT not 2 nights ago I played for 4 hours and not an issue to be had. THis happens randomly. So this time I got some info as to what the issue may be.

Can anyone tell me what this menas?

Reseat Ram and GPU (pull it out and re-insert firmly) .... Rotate Ram to diff slots.

Could be PSU(intermittent heat related) or Vid drivers ...

Must sometimes manually clean out all vestage of previous video drivers before adding newer (or older) video drivers.

I guess you already know about ShortStuff's Fabled PROBLEMS doc ? ?

It has been known to help isolate just this sort of issue . . .

What are your complete system specs? The problem you describe is often caused by RAM problems. What RAM test did you perform? Have you manually set the RAM speed, timings, and voltage to their rated specs in the BIOS? If not, that's the first thing I'd do. I've seen more than one system pass multiple runs of Memtest86+ but have stability issues during normal use. Manually setting the RAM values fixed the problem on those systems.

What SS said ...

Take the published timings from the data-sheet (or packaging) which came with your RAM . . .

(1) Go into setup to the RAM timing fields and *MANUALLY* enter the values that the manufacturer published/sent with your RAM (from the mfg data-sheet ... NOT auto-sensed).

(2) At the Top-Level BIOS/SETUP screen/menu choose "SAVE & EXIT" . . .

(3) Go back into the Setup Screens and make sure the manually entered manufacturer's RAM timings were properly saved ...

(4) exit setup and allow normal boot ... should be OK after all this.

Thanks for the link.


ASUS M4A79XTD EVO AM3 AMD 790X ATX AMD Motherboard

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL

CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power

I have reseated the ram, and tried the 2 sots closest to the CPU but the system wouldnt boot up it hung right before POST? no beep or anything like that. I have reseated the vid card before but ill try it again. I changed the PCI-E cable as well as the PSU connecter. I ran the windows memory test, my memory has been set at 1333 and 1600 same issue locks up then pc reboots. I havent messed with timing on the memory. BUT I will find what the recommend for timing settings.

THanks for this input!

Oh I wanted to add that I got this vid card a 2 weeks before the rest of the stuff arrived and never had an issue on an older build I had tried it out on.

HEY ...

If you have not updated your nVidia Drivers within the last ONE week then I would do that first !!

I just got back from their dnld site and I am pretty sure there is a newer fix than you currently have.

Try that first and ... we can continue, if necessary. I don't think we're going to lose this patient.

Roger that. Oh btw the motherboard isnt on the memory site scceptable list, but I have seen ppl running this Mb and the ram that I have. In my memory timing I have a 1t and 2 t but no 2n I set it to 2t.

As you probobly know the Amd 955 memory controller works at 1333mhz, anything above that is really not producing much benefit. Also there are some adjustments to CPU mem voltage controls that may be neccessary.
If you examine the first 2 or 3 pages of user comments at newegg you'll notice alot of rma's happening, even with a quality manufacturer like G.Skill *&^!! happens.

So, really, for the record ... There is no substantial performance gain to OCing 1600cas7 Ram, at $120 to some basic 1333cas9 generic sticks at $94 ? ... with a 955 ?

What about a 965(C3) ?

Anyone get anywhere with this? I have a '955, the Asus M4A79XTD EVO board and the GSkill 12800 memory per a "good deal" from the egg. Started with XP32, things went okay with 4 Gb; just tried moving to Win 7 in the past couple weeks with some luck. Tried to add another 4 Gb of the F3-12800CL9D -4GBRL (DDR3-1600) memory and the PC looks like a baby's face when they first try sour lemons when booting. I've had to pull the extra memory out twice to get anything to boot, and even then stability takes some warmup time at the 1333 speed.
Tried calling Asus, they outright disconnected the number the 'egg gave me. At this point I can only return the extra memory, but I'm half thinking of just going to another board manufacturer (regrettably like my LAST Asus build). Updated the Bios to the latest (2001); any ideas would be appreciated.
I should note, I have a 700W power supply, Nvidia 570 with updated drivers, Caviar black SATA-II that all seem to work fine.

@ Uber-User - You should start your own thread instead of hijacking this one. Many motherboards have stability issues when filling all the RAM slots. Often you have to bump up the RAM voltage a bit higher than the rated values for stability when all the RAM slots are full. It looks like your RAM is rated at 1.5v. I would try manually setting the RAM voltage to 1.55v or 1.6v and see if that helps get your system stable.

It's also possible you have a bad stick of RAM. Have you run an overnight run of Memtest86+ to test for RAM errors?

This fix sounds funny, but I had this happen to TWO computers in my house, it fixed it both times.

Well, not trying to hijack this thread. When I did a search with the Asus board I have (the same as CWest, probably due to the same deal at Newegg), this is one of the links that popped up.
Doing a little bit of research, it seems the Phenom X4 955 doesn't like 1600 DDR3 memory (feel free to verify). I've run across specs saying use the DDR3 1033 "unganged". I've fiddled with voltages, timings as suggested here but I think that's the root cause.

Oh, I did run across this link of approved boards for the 955 processor at this link: (http://products.amd.com/de-de/RecommendedMBResult.aspx?...). The Asus board we both apparently have isn't listed, so it kind of falls under we're on our own. Not sure which components I'll replace, anyone want a good deal on some GSkill memory? <G>

This is the first time its done this since my last post. I thought I was out of the clear but no...this time I was playing Borderlands with a friend who strangley enough had his vid card tweak out and his machine rebooted or he did I dont remember.
