eMachine 6805 Overclock Thread

[swaaye]

I have one of these wonderful eMachines notebooks. I've been reading up on here how to overclock the CPU and have been having a great time playing with ClockGen.

I can get the CPU up to 2100MHz without much effort. It runs through prime without any errors. Problem is....AGP clock. The 9600 gets all fruity up around 74Mhz, let alone the 79Mhz that it's at for 2100MHz CPU. UT2004 will just stop and ATI's VPU Recover saves me from a hard lock.

Has anyone figured out any tweaks of AGP timings to get it stable? Does anyone else have these problems to begin with? I tried AGP 4X and disabling fast writes. I also went into advanced smartgart and turned off AGP Read and Write, which killed performance a ton.....

Eh, who needs a Mobility 9700!?!?! I can get this 9600 up to 445/240 without much trouble. ATITool is the niftiest tool to figure out the max clocks.

445/240!!!! 9600s are unbelievable overclockers. That's from 300/210 or so too! (Still haven't solved the AGP clock overclock issue so I only overclock the GPU when I'm at CPU default)

I want to hear other 6805 owners' tales! C'mon!

405/220 here

Anybody open a 6805 or 6807 up and take pictures? I'd love to see what the inside looks like.... I'm especially curious about the cooling. Seems the thing has a cooling fan for the 9600 too....

Does overclocking void the warranty? If I trashed any evidence of overclocking would Bestbuy/emachines still be able to find out and not honour the warranty?

[swaaye]

I don't know how they'd tell unless somehow you actually cooked something. I can't see that happening as long as the cooling is getting air though. Instability comes long before barbeque too, in my long overclocking experience.

If you need warranty service, go a full restore after backing up everything important. I wouldn't send them all my data anyway.

What settings are you using to OC to 2100 and beyond? I've been real hesitant to do any serious OCing because I don't want to fry anything by using too much voltage. I'd like to get an idea of what seems to be safe and go from there.

Thanks

also to do with overclocking, anyone know how to monitor the motherboard temp?

370/256. Memory can get up to 263 in the m505 X artefacts free :headbang: :headbang: :D

[kristoff]

is there a way to asynchronously set cpu and agp clock settings? Also has anyone posted links to the overclocking tools, which are used in these discussions?

[swaaye]

No, the K8T800 has a well known limitation of having a locked AGP/CPU bus ratio. Tragic, I know.
