Back to spinning symbols-covered rabit corpses above my rad... tongue.gif


If I may bud, the 8350 chips have terrible IHS planes. I recently lapped mine to receive around 10C off my stock load temps. There was a circular valley that ran around the core. So between the center and edge of the chip there was no good water block contact. Something to consider, obviously you would have to check yourself.

Yeah, someone noticed it when I joined the club. Not to mention the dents in my H80 and cpu block... frown.gif I sanded my CPU's a few days ago, here's what I got so far:

I stopped sanding after 2h, cause that's ridiculously long. I should also have bought some 2000 grit and a buffer, the top still is a bit rough... 220 -> 800 -> 1500 doesn't make it as smooth as I hoped.
And yeah, it did take about 5-10C off. That was worth it. The next time I take the thing apart, I might spend one more hour sanding it off to complete copper. Maybe. Damn that takes forever.

Mine too. 2hrs and said Ill finish another day. wore me out after a long day at work. I got the kit and it had 400-800-1200-2000-2500 grits.

Finally got in some IBT runs at 5ghz!! I had 4.9ghz 24/7 stable, with not much luck above that. Got in 5 runs before linpack.exe broke, still a good sign compared to a complete freeze up. Now to reach the next milestone.....5.2ghz?

Perhaps that is because cooling and proper voltages are the primary components of high overclocking . Perhaps we have overlooked something about vdda on Asus but 2.8 volts on 24/7 will eventually damage your hardware. Check it out with Asus if you don't believe me.

At 4.7ghz on my 8350, up from 4ghz stock, if I do anything less than 2.8v some of my cores fail Prime95 in the 2nd test. It is the cores in the last module usually, but sometimes it affects the first module as well. If I leave VDDA on auto, 2.4v, the cores fail. If I have anything less than 2.8v, the cores fail. This is with all the same settings and the same voltage on the CPU, 1.475v.

If it didn't do anything on ASUS boards, then why does changing this value make me stable? I can pass a whole run of P95 with my OC and 2.8v VDDA, and 10 loops of IBT, which is stable enough for me. With the value lower than 2.8v I can't pass Prime95 and I get a system hard lock (frozen mouse cursor) in IBT. If it didn't do anything this wouldn't be the case. As I stated, in my experience the value helped stability on Phenom IIs as well.
Funny part was I read on it some, now cant find the actual numbers but it must have been 2.9v or more. I had mine at 2.8554v and I was stable completely. But then everyone threw a fit and I couldn't find that number anywhere so I don't go over 2.65v just to be safe.

After Wednesday you won't see me on the forums for a while. I am having some serious surgery next Friday for an aortic valve replacement. I'll probably be in hospital for 4 days and in recovery at home for at least a month. I hope to be back in fine fashion as soon as possible. The bosses at my old job managed to give me a heart attack 2 years ago when I was standing up for my co-workers who were being hounded into resignations and firings . I have been retired for a year the damage is done. I have no regrets. I still have many friends in the workplace and they all miss me. In any case I am trying to prolong my life for a few more years so I can be there for my wife , daughter, and grand daughter. Take care. Say hello to Gerty for me.

You will have to move your computer to your bed! haha. Best wishes with your surgery going well aswell as your recovery. Hope to see you back sooner then expected biggrin.gif

I recently too had surgery, so I know what it's like, I hope everything goes well and the fasting doesn't make you want to hurt people lol. Rest well mate. Wishing you a fast recovery smile.gif

I've always wanted to sand down my chips, but I though that removing the layer of Zinc to expose the copper would make the IHS get covered in oxidysation? Especially when constantly heated and cooled (idle and under load), as it excellerates the process.

Once you sand the IHS down to the copper, are you having to constantly maintain the IHS to keep oxi at bay? How much of the IHS can you remove? I assume the less material there would be between chip and heatsink, the better heat transfer there would be.
