Is it possible to overclock a e8400 to 4.5ghz on an gigabyte ep35-ds3p on air if so what kind of cooler do
I need?

Thanks,

Maybe you could overclock, but not from 3 to 4.5 its too much!

I just thought that because most people can overclock it to 4.0ghz on a stock cooler that it might be possible to get another .5ghz from using something like a turniq tower.

I have heard people getting the E8400 to 4.4 ghz, but never 5 ghz. I would suggest a Zalman cooler though, Zalman so far still has the best coolers imo.

it also depends on the quality of the cpu, if it's a good one, there is a possibility of getting to 4.5, at the same time it is also affected by other factors such as your cooling fan:D

On air cooling it would be a bit tough. The best air-cooling would be the ThermalRight Ultra-120 eXtreme, but if you really want to have a shot at 4.5, I'd go for water cooling.

Yes, you can run at 4 GHz with stock cooling, but I can guarantee you won't have that processor functional for very long.
I'm scared to even push my E8400 past 3.5 GHz, 52° C max load. At 3.75 GHz with stable voltage, I get 56° C.

thanks for all the help guys,
what about the motherboard, for the e8400 I would have to set the fsb to 500(9x multi 9X500=4500) will the ds3p go that high?

thanks,

I've had my 8400 to 4.8 on water. The world record is about 5.4-5.5 on phase last time I checked. On air I have one 24/7 stable at 4.5 @ 1.51v max temp 62c at 100% load.You won't get there with a Gigabyte board with sane voltages. You'll need a DFI board and lots of VTT and GTL ref tweaking.

what kind of air cooler were you using?


thanks,
Alec

A TRUE with two Noctua NF-P12's in a push pull configuration. I used Coollaboratory Liquid Pro compound and a lapped IHS.

Thanks for all your help I think I just stick with trying for around 4ghz

You should have no problem. I know those Gigabyte boards quite well and there are a couple of threads here with some tips on overclocking that'll get you in the ballpark. If you need help feel free to ask.
