Vostro 1400 overclocking, its crazy.

I'd appreciate it if anybody can post a guide regarding putting arctic silver 5 on the gpu and cpu. Thanks.

Even without pics its fine.

 

mrg666 I'm experiencing something wierd using ATI Tool when overclocking.
When "Scanning for artifacts", Many times yellow blotches and dots will flash across the "hairy cube", but the scan still says no errors detected.
What are the yellow blotches? Aren't they artifacts that should actually be identified as errors?

 

That is because of overclocking beyond stable limits. I have seen Atitool missing some of the errors before. You need to reduce either GPU frequency or memory frequency. I would recommend reducing the memory first. If it does not help bring it back to previous value and do the same with GPU frequency. If none of them works you should start overclocking from the stock values again. Hope this helps, good luck !

by the way, you can now overclock with the latest 167.26 drivers, they do overclock!

AWESOME mrg666, what 3dMark scores/ fps are you getting?
I'm gonna try those when I get home.

Also, how come those drivers aren't listed on the main page of drivers, and only in the forum? Is it hidden for a reason?

 

Hi Everyone,

I've been following this thread for quite some time and can't think of a more valuable thread for the 8400GS, it's great. I have a quick question though because I'm not sure if it's been covered or if I just missed it...

I'm using the following tools and drivers:
- Laptop2go drivers - 167.26
- Riva Tuner
- Ik8GUI or something... can't remember the full name, for temp monitoring.

Currently, I'm able to overclock to the the following numbers without any artifacts:
- GPU - 530 - (56-66c)
- Shader - 1200 or so
- Mem - 750

My biggest concern is with the temp monitoring program, it shows the Chipset at 96c, which I'm sure is not a good thing. I don't get any issues when gaming, and it seems to run well, but I really don't want to melt the lappy. Is there something else I can use to monitor temps so that I may compare and see if I'm even getting anything accurate? Is this temperature even acceptable? Please help, I'm really sure that the video card can go much further, but I won't do so until I know if these temps are going to kill it.

TIA,

I run similar temps when overclocking and I think we confirmed that up to 130C is in the acceptable functioning realm of this GPU.

So as long as the I8KFANGUI is not off by 30C or so I think we are ok.

Also bear in mind the GPU probably has a thermal cutoff built in and, at least for me, the system never gets physically hot or even very warm around where the GPU is located so I think it's pretty safe...

 

Thanks Devedander,

That's pretty inspiring, 130c? Is that the chipset on the GPU, or the chipset on the mobo that it is monitoring? If 130c is the max, and I'm only at 96c, I've got a boat-load of headroom. It's time to take this GPU higher.

Does anyone have a way to go above 750 with RivaTuner on the memory? My slider bar stops at 750. Is it in the settings somewhere? Thanks.

(=(=(=(= 8400GS FTW!!! =)=)=)=)

 

You know I only saw that number here mentioned by someone else who said they had confirmed it... I am not sure the details on the 130C figure...

 

Can anyone else confirm?

Most CPU's have a threshold of 70c while GPU have 120c-130, anything below 100c is fine ON MAX LOAD.(you got big problems if that's idle). But remember the higher the temp on your CPU and GPU, the more unstable it becomes so even though it looks fine at 60-80c, once it reaches a higher temp your GPU will start getting artifacts or crash, but yeah. I can assure you that the threshold is 120-130. Although if you use the nibitor bios it says that the threshold is 110c. So it's up to you to find out
