Overclocking the HD3850...

[oscaryu1]

How far should I get? I have a 70mm fan blowing at it from a PCI Expansion slot. Blows directly at the heatsink, not the fan. So that helps a bit... it's adjustable speed and is currently at HIGH....

How far of a overclock fan you predict? With no artifacting that is...

Ooh, another HD3000 series buyer... I may have to go with the HD3870...

The heatsink is covered in plastic therefore I don't understand why having the fan blow on it does any good. And I don't know how much you can OC it but since at stock speed under load the thing sits around 90c I wouldn't OC it much.

 

[oscaryu1]

It doesn't. It stays pretty cool. Seeing as you don't have one...

Im not sure on the overclocking, i used riva tuner to turn the fan up a bit.. it was idle 60c and load 90c, i turned the fan up to 50% fixed.. and now idle 38c and load 65c

Regardless, even though the cards are different, turning up the fan speed will help.

I saw someone with the 3850 get 725/850.. but i don't know if it was stock cooling

But will, the first one was DOA, the second one comes today (to bad I'll be gone).

I still can't imagine how you have the fan blowing on it, care to elaberate?

Oooh When my RAM comes back Care to elaborate how you turn the fan speeds up?

(and I haven't shipped the RAM yet you know why))

download rivatuner, click the small arrow beside the video card name and select low-level system settings/fan. Don't do 100% unless you want the fan to die

 

[oscaryu1]

Man my cameras good

Hmm.. how many % do you recommend for mild overclocking? (if possible...)

 

[ThatGuy16]

I dont know i set mine to 50%, but they are different...


google?

 

[oscaryu1]

Meh, sure I'm sending my RAM back today Hopefully I get it back by next week. Then I start to OC again

-----------------------------------------------

Does bad RAM affect overclock?

 

[Joe2005]

@Oscaryu1, Is that fan on the side blowing in, or out?

 

[oscaryu1]

Which one?

 

[oscaryu1]

Oh wait, sorry. There's 2 fans actually. The rear one stinks (Ahh... cheap rosewill )

There's 2 80mm case fans blowing IN from the side. There is another expansion fan blowing IN to the GFX. There is 2 PSU fans blowing OUT. And one cheap and slow and weak Rosewill 80mm case fan blowing OUT.
