bad chip
That chip must get really hot when the vdd is up. I'm thinking I'll hs it if I ever go higher on the vdd. I'm at 1.75v-1.77v right now with a fixed resistor.
I put ramsinks and a 40mm fan on my 8RGA MOSFETs.
So far I have a 2500+ @ 2750MHz, 2.1v.
we want pics :DQuote:

Ask and ye shall receive!
Here's the fan over the MOSFETs. You can barely see the ramsinks underneath it. I used Arctic Silver thermal epoxy to attach the ramsinks, and regular epoxy to glue the fan to the tops of the capacitors on either side of the MOSFETs.

At 2.1Vcore the machine would reset after a few minutes without cooling. With ramsinks it lasted a bit longer, but it was still unstable. With the fan it's stable.
Now it maybe just my chain if thought here, but if Epox give you the option of 2.0 Vdd in bios as with the 8RGA then I would expect a normal board without any mods not to fail with components frying. I now don't run at Vdd 2.0 24/7
Now I got my 1st board replaced FOC but I would not if there had been any sign's of any mods, even if it was extra cooling
If is a different matter with a modded 8RDA
What do people think?
I expected it to be able to do this stuff without modding too, but mine didn't. Ah well. It does it now, modding is fun, and it looks cool. I'm not complaining.
Those mosfets are designed to be cooled by air from a heatsink.
Running a prommy you will get stagnant hot air building up and possible instability... so a fan is a good idea.

You might also want to put a sink on that bare voltage regulator chip just above that mosfets fan.Quote:

Ah, good point. That makes perfect sense.Quote:

I've never felt it when it was on, but I didn't think it got very hot since it doesn't look like a high power chip. I'll check into that.Quote:

Yeah that Vcore regulator is indeed a hot little bugger, especially when you're using high Vcores!
M@tt, my original thought is to agree with you. That is, if it is an option in the bios, the board ought to be able to do it 24/7 without failing. However, maybe that's being short sighted. We know that manufacturers put option in the bios that could kill ram or cpus, so why not something that might kill the board, as long as they are willing to RMA it if it does. Let's us OCers at least have the option of running it if we want without fear of blowing the board up without recourse. Otherwise, they will get conservative, like say Abit, and only give us 1.7, which we then have to mod anyway, so we might as well have had nothing in the bios, because we won't be able to rma anyway.Quote:

What the extender plugged into the atx power coonector,did you make it yourself or buy it?Looks rather handy.Ta for any infSmiffy
