This is THE most important tweak you can do folks, don't doubt it for a second. I couldn't even run my system for more than 30 seconds at 133/133 for a Athlon 1900+...but now...oh yeah baby! Running great at 1.71 Ghz (143/143) and gonna tweak some more to see how high I can go of course....
Anyway, MAKE SURE YOU DO THIS MOD!!!! |

I assume you mean "auxilliary fan hanging underneath the CPU heatsink", not under the chipset heatsink.
That is fine, but have you reattached the heatsink with something else than the goo originally used? |

i tried putting toothpaste on a plastic just above the cpu casing. it became hard just like a gum. does this thing really work just like a thermal paste?

I am no expert
but usally if somthing is not designed to do something it probally won't suck it and see (not the toothpaste) ONLY if you are prepaired to loose an expensive part of your computer  |

how about reversing this mod? | ||

can this be reversed ?
can I remove the glued down heatsink cooler?

yes, if the glue can be removed easily. otherwise, dont force to remove the heatsink if it wont budge or it will be....

I just figured I would throw my 2 cents in. I was haveing alot of problems with the k7s5a (after the cpu fan died and of corse I replaced the fan). Every time I tryed to play max payne 2 it would windows blue screen out (which is normaly a memory issue). I figured I would try this mod to see if it made any difference. I had a heat sink/fan combo (looks like a blue orb but isnt). So I thermal epoxied it to the north/south bridge and every thing works fine now. I havn't tryed to over clock it yet but before it would run stable at 147 fsb. I'v heard there is no way to boot past 150mhz.

Yep. I'll confirm that. can't get to boot my 2100+ Tbred B with my friend's PC2700 ram to boot (133/166, which translates to stock speeds), even with slowest timings.
 Kinda pissed, I know my 2100+ (even my ram, if I bothered to do some soldering for volt mod) wants to go higher, but i'm capped out at 150/150!  lolAthlon XP 2100+ Tbred-B @ 2400+ (1.95ghz)

Chipset mod | ||

Posts: 13 (11/25/03 17:39:11) |
I have a K7S5A version 3.0 and have not modded the chipset yet. I am able to oc the FSB to 147 without problems. I changed from DDR 2100 to DDR 2700 and now it will go to 166 with CPUFSB (166 x 11.5 = 1910 Mhz)(on an 1800+) without the chipset mod.
Would like to go higher now. Not sure if I should change the multiplier of mod the chipset. Chipset is cool to touch. Board is one year old. Still need the mod? Thanks, Tom |

chipset heatsink replacement - great idea! | ||

Can't believe how $hite the thermal de-coupling is here.
I just read this thread and though..hmmm, give that a try...got some thermal paste lying around and see how it goes. Before - I had a 1.67GHz oc'd with the Honey X BIOS to 138/138 bus so 1.72GHz processor speed. Pushing it to 143/143 was often a bit much as it wasn't entirely reliable. My memory is 2100 DDR (266MHz). My old orange heatsink from the chipset was only warm to the touch when i took it off. Now - Re-pasted the processor heatsink back on and also re=pasted the chipset heatsink to an old Pentium 1 heatsink which is quite big compared to the old one!!!! They cam away very easily which is worrying as this would have meant a gap between the tape and the metal. I can now run 143/143 solidly without crashes so I'm chuffed! DO THIS - IT REALLY WORKS AND IS DEFINATELY WORTH DOING! |

I can't believe when I see this chipset mod guide.
It seems making such a big difference. My system is pretty hot (comparing to other users here) and I am using 2 x PC-133 SD RAM. The system only freezed occasionaly (once in a couple days), so I am not sure if it's overheating - but when summer comes this chipset mod may become handy. BTW, thanks to Milt for your step by step illustration, very helpful: radel.inet.net.nz/chipset/ |

ive done this. first i cleaned the chipset and then lapped the original heatsink. put some splat of grease, put 4 drops of glue on corners, then replace the heatsink. but i only got 1c lower
i mean i did everything right. since the super glue is super tight and wont budge, im goin to try to put another heatsink with fan on top of the heatsink, so that i will have a dual heatsink atop each other.k7s5a (dunno the version but it has brownish board and orange chipset heatsink)

Quote:The system and CPU temperature will not be affected by the chipset heatsink fix. What it does is lowering the temperature of the SiS735 chip. The SiS735 has no onboard temperature sensor anywhere near it, so you can't measure the difference without some extra sensor attached to it. |

I also have a 110 mhz morgan core duron, I lowered my multiplier to 9, with a fsb of 133, resulting in a totally stable 1200mhz. haven't done the chipset mod though it sounds like a good idea

Before doing the chipset heatsink mod my PC was crashing after a few seconds in any game, after the mod it became rock stable and only had some weird errors in prime95.
(which went away when I upgraded from 2-sticks SDR to 1-stick DDR). |

I did the chipset mod but without putting any hatskin back.Before my cpu worked only with 107(it's a arga 950
athlon) now it works at 110.I have 128 sdram so at the moment I dont think that no hatskin is a problem. It's hard to find a 486 hat in this parts, I was wondering will it work with any cpu hat? |
