Decent cheap heatsink for Opteron 165 overclocking?

[thirdlegstump]

Looking for a moderately priced ($20-$30) heatsink for overclocking my Opteron 165 in an Assrock 939 dual board. Hoping to achieve 2.8GHz on air. Any suggestions or is this unrealistic?

i really don't think it's worth the risk

do you have the stock AMD one?

Nah I bought an OEM so no HSF comes wit it.

AFAIK thermalright makes about the best heat sink's there is I'am planing to us my SLK948U if it will work when I decide to upgrade to a 165 or 170.

How does the asrock and OPTY work together?

Don't have the opty just yet. Supposed to arrive tomorrow. I had a 3200 Venice before I bought the opty and was able to push it to 2.5GHz without mucho sweat on the stock retail HSF.

SI-120 may be expensive. But you definitely need good cooling for your goals.

Agreed and if people can pay extreme prices for water and phaze change the y not throw out a pretty penny for a nice air cooler.

Making the assumption that this is for a Socket 939 Opteron/motherboard, then the best bang-for-the-buck heatsink (excepting the retail one) is the XP-90. That being said, the Scythe Katana is the best, followed closely by the XP/SI-120. In truth, they are all within a few degrees of one another.

Seeing how the ASRock doesnt allow for very high vcore settings, you won't be able to put much to it anyway's, 1.4v maybe?. So I don't think you will need to spend more than what you are budgeting.
