i have a g400 max with standard cooling sitting stably at a speed of 165/220. however i have aquired a socket 7 heatsink that measures 50*50*15mm (with a 50*10mm fan) and am looking forward to putting this to use. i shall use artic silver thermal epoxy to stick it on the core, and i shall also buy some aluminium ramsinks that measure 32*12*12. again i shall attach these using a.s thermal epoxy. also i plan to use the existing heatsink on the back of the core if the wire for the fan stretches that far. the reason for doing this is so that i can play the newest games @ 1024*768 with 32 bit colour as at the moment my system is struggling with nolf and project igi.
has anyone here perfromed a similar operation with a g400max, if so please can you post your maximum stable speeds reached, and any concurring performance increases.

cheers roadie

My G400 Max is currently @ 170/226, this is with a FOP 38 Heatsink and 20 CFM fan on it - Which doesn't help much because of poor contact with the chip.

Lapping that baby just wouldn't make it flat, for however long I tried. http://forums.murc.ws/ubb/frown.gif

Whats holding you ppl back is prolly the ram. Get some ramsinks. Stock MAX cooling is pretty decent. Just frag-tape on a small hs to the back, and u'd be fine.

If you want more cooling that that, see if u can find a Blue Orb from ThermalTake. That will give you as much cooling as the G400 will ever need.

But the trick is RAMSINKS. They'll give you more results than a giant FOP38 http://forums.murc.ws/ubb/smile.gif

I have my G400 (non max) running at 333 core/166 memory. I am using a homebrew watercooling setup with no peltiers. I can run it up as far as 366/183 but will occasionally get blue screen (Windows Protection) errors. 333 seems pretty stable. Is this a decent overclock for a G400?

Sorry, my mistake, I was quoting PLL clock speed, not core clock. The PLL clock speed is 333, not the core. Sorry for the confusion.

It's the cooling in my case. My RAM will go up to 232 Mhz, but the core just flips out higher than I have it now(ie, I get the broken mirror effect).

Guess I have a hot runner.

175core/233mem (powerstrip)
-> drilled holes in retail heatsink
-> replace thermal glue with thermal grease
-> used small thighwraps to fix it back on the card.
-> screwed a RadioShack 40x40x10 @6500 rpm fan on it.
-> put small ramsinks on the mem chips using fragtape

I use ram heatsinks with thermal glue, and a Thermaltake Blue Orb on the chip

Works stable (175/233)
