So I finally was able to try out one of these fancy smancy Winchester's in replacement of my CG Newcastle as my mobo was holding me back due to a RAM upgrade (and we can't have that overclockers, now can we??). Anyways, for first two weeks or so, was stable at 2.7Ghz @ 1.6v, 270x10 but felt I was pushing a little too much and dropped down to 2.6 @ 1.55v. Hell I even got it to boot at 3.0gig just to take the screenshot. However, just recently, I've been getting some very odd issues. I haven't throughoughly tested these problems because I am going to reinstall AGAIN because of some different hard drives, but I think I'll run into the same problems anyways. Basically, the problem is this: I play World of Warcraft, and what was happening at 2.6 gig was after playing for say two hours or so, sometimes more, my game would either lock and drop me to a blue screen citing nv4disp.dll as the problem, or go into one of those horrible sound loops where it would loop the sound, and in between each sound loop there would be a horrendous screeching come from my speakers. Dropping down to 2.4 so far has alleviated this problem, but man I really want that extra clock speed and memory bandwith back. Vid card even at stock settings at 2.6gig causes this, but I can overclock the video card at 2.4gig and do not see this issue, so I am not sure it is the video card. Reinstalls of drivers as well as Windows has not fixed this either, so again, I can't say I blame the video card but why in the Hell is it cititng nv4disp.dll as the problem? Also, what is up with the horrendous screeching? A buddy said this might be overheating, but is this true? I am using an SLK-948U and a Vantec Tornado, so I HOPE it's not overheating.

The sig info below is what I am using currently, so I don't think it's an issue of parts either. My CPU is a week 48 CBBHD I am *pretty* sure, as I'm at work, so the stepping is of good quality as well. My HUNCH lies in either my application of arctic silver, which I followed directions and placed a small drop of the stuff on my core and then bolted down my heatsink so I don't think I did that wrong, OR a cooling issue with my northbridge, as I didn't remove it and check the TIM present on the stock cooler. Could THAT be my issue perhaps, northbridge overheating? I know the chip isn't the issue, as in it's early days it was running Prime at 2.7gig nonstop for 10+ hours.

I need to install some more 3dapps and compare the issues to both World of Warcraft and Prime95, but basically what perplexes me is the deterioration of the CPU overclock, the nv4disp.dll citations in the blue screen, and the sound looping/screeching locks. Any info any of you hardcore folks could supply me with would be GREATLY appreciated, as I know the headroom is there, but something just isn't playing nice anymore.
 
I would check the thermal paste to make sure its on right. Try clocking to 2.6ghz and run memtest for a bit. If memtest is fine, then try prime95. If that is fine try running prime 95 and 3dmark2001 at the same time. It could be possible that once your powreful CPU and video card both start drawing power that the PSU is being taxed to its limits. My antec 400w smartpower was being drained to its limits with my system so I replaced it with 500w, and your system draws considerably more power at 2.6ghz.

Possibly at 2.6ghz your agp bus is somehow running out of spec?
 
1) what speed are you running the memory?
2) to run *mine* p95 stable at 275x9, mem on the divider, i had to set my vcore to 1.45 + 8% over
 
It could be the chipset overheating problem, because I noticed that when I used 3d applications causing traffic to AGP bus my chipset warmed up quite a lot. Of course this was before watercooling. :)

So I would at least check if there is enough thermal paste under chipset cooler. I have seen msi boards with almost no thermal paste including mine!!!
 
brake: In regards to the agp bus, I've checked many times with clockgen, and it was indeed set where it should be. Also, for awhile I was running 2.7 no problem, so I don't think it's running out of spec. I did consider power and if it comes to it that is definately an option I think I'll have to look into. Man I figured 33A on 12v was enough too :(

Scar: Lot's of speeds to try different things, it's stable at 270 @ 2.8v though I've used it in my machine as well as other's machines at rated that high no problems. 2.8v is as high as I want to go but I think according to PDP it can go higher I forget what it's max *rated* is but it's something like PC4400 @ 3-4-4-8 or something. I did have it at 260 @ 2.8 before the problems started cropping up. Gonna try 275x9 when I get home and see if I can isolate the problem further from anything but CPU or heat. The RAM was why I upgraded from 754 so imma cry if my RAM is causing me trouble :(

So yeah definately going to check the TIM on that NB....fabo your prolly 100 percent right and MSI did the crap job of the paste for my NB.

I'll post an update when I get home, let ya know if MSI screwed me or not. Thanks for the suggestions so far guys, and if there's anymore, keep em comin! :)
