Sam,
The 955BE/C3 I have is 125w. I did see a picture of a Megalump that had squeezed all the stock thermal paste that comes applied to opposing outsides. To my way of thinking, that would be caused by something being bowed out, more likely the Heatsink, because it is harder. I would think if it was the heatshield on the CPU, it would break the CPU. You could see in the picture, where it was wedged to both sides, with the middle almost completely clean. I read a lot of complaints about their heatsinks not being flat or level.

Yeah AFAIK Russ's chip is one of the best clocking 955s I have seen.

Also Russ, just got done installing the Eco-120 on my friend's 1090T. I must say the quality struck me and the install was a snap. And one of the only aftermarket coolers I've seen with a proper TIM application. So well done I didn't even bother to clean it up. I just slapped it on, lol. After seeing his temps I can hardly imagine that lapping or different TIM would make a difference. It runs cooler than my 940 does with the Tuniq fan maxed.

Speaking of which I will finally be getting some new fans for my Tuniqs. Specifically Noctuas, but I'm not sure which model I want as there are so many and not all are made for CPU HSFs. What woould you recommend for a good airflow/noise ratio and 24/7 use sandwiched in a heatsink?

Trying to get stable at 4Ghz again since heat isn't an issue anymore but I'm getting instability (BSOD) after 1.5-2 hours of linpack (crashed at ~41 pass @ 4GB). Any ideas on what I need to raise? Some say put the IOH up to 1.3v, which is probably what I'll do next since it seems to respond well to NB voltage boosts.

current settings -
Vcore [1.33]
CPU PLL [1.88]
QPI [1.33]
IOH core [1.22]
ICH core [1.22]

TIA,

Just FYI I am currently making this post using said Gigabyte board. Seems fine to me so far... next couple hours will tell me if my theories are correct. User error might have been the problem here. He was running some wrong settings for his OC and the 2.1v RAM was running at 1.8v... Can't say for sure though. We'll see what the future holds.

I do know the dumbass tried running other CPUs in the board to see what would work and couldn't get it to POST. Yeah he was still running his OC settings for a completely different chip >.<

Thanks a bunch for the insight Russ but I wasn't the one having problems with the board. One of my friends recently started OCing after installing a Coolit Eco, but has absolutely no clue how to scale voltages and clockspeeds to match the rest of the system. Thus the board was having random shut downs and at times wouldn't POST at all. He has since given up an moved on to a Biostar 890FX board(fitting as he is the one with a 1090T). The board was given to me on the basic premise of "if you can fix it, keep it."

So far, the only thing I did was load the fail-safe defaults, set everything to stock for my given hardware, and try a little OCing with known 100% stable settings to see how the board behaves. So far, I have had absolutely none of the problems he told me about. I think he truly just screwed up his OC and got rid of a perfectly functional Gigabyte motherboard.

The previous issues were shutting down randomly, even after showing 100% stability in IBT, and locking up in the BIOS. Since I have gotten the board and set it up properly, it has been perfectly well behaved. Been playing games, listening to music, and posting on forums for over 5 hours now and not a single hitch. Previously, it wouldn't make a half hour without locking up or instantly shutting down.

My theories for his issues are as follows:

- Wrong voltage to sensitive parts
- No airflow to the VRMs after installing the Coolit ECO-120(though he does have a HAF, same guy with the 1090T and dual 5870s)
- Possibly a shorting issue with his mounting method
- A bad OC that he didn't recognize, considering Gigabyte AMD boards usually bluescreen or lock up on the desktop with a bad OC

Whatever it was, at stock settings, and at a mild OC I have had zero issues including 10 runs of high stress IBT and 3 hours of Prime 95. I think it was simply user error.

Either way, the offending party has now agreed to let me do his OCing for him. He has no clue how to use the HTT or CPU-NB clocks and has replaced several boards in the past thinking they were broken. One had burnt VRMs(That's what you get for putting a 1090T into a 780G board...) and the other turned out he simply wasn't screwing in his DVI connection and it caused constant rebooting and POST errors(this is the second of the board he's used, having replaced the other one for the DVI issue). This one seems like more of the same issues. Can you say PEBCAK? LOL
