Have ?'s and need help OCing E8500

[Homeboy2]

i dont have experience with that cooler, the true is fantastic but overpriced. Many peeps here swear by the Xigmatek rifle. as good or almost as good but a lot cheaper.

+1 The xigmatek performs very well for the money.

I got an E0 e8400 and I can do 4.0 @1.22V under load. Its VID is 1.25 😀

Only downside is I bought an nForce motherboard for my SLi 8800GT, so 445 is the chipset's limit.

yeah that's cause you got an E0 stepping. My E8500 is C0 🙁

mines a e8400 and it sucks as it needs 1.4 for 4.0ghz, 1.5 for 4.4ghz and 1.6 for 4.6ghz.

My C0 stepping 8500 is not much different... I need 1.4875v to get 4.37ghz or 4.275 for that matter. I could go higher on speed but heat becomes too much of an issue on air even with a good cooler and good case ventilation. Heat nowadays is really a multi faceted problem that can be costly and difficult to deal with. Take high speed DDR2|DDR3 that is already hot at stock, X48 NB thats very hot at stock, video thats very hot and overclock it all. Add to that drives, power supply, SB, audio and a very hot OC'd E8500 and you have major heat problems to be dealt with. My system is pretty well vented but will heat the room (even w/ AC) as much as 10-12F when gaming for extended periods. The biggest culprit is my 8800GTX which is like having a space heater blasting in the room. I'm going to get a 4870X2 but its even hotter.

I totally agree with you man. Once I got my 4870 and E8500, temps went up by 10 degrees within my system (according to Asus AI suite). I have 5 fans inside my system (1 - 80 mm fan at the top, 2- 80mm the sides near ram and VGA slot, 1 - 120mm at the front for intake, 1- 120mm at the back for output) so this is serious business here. You are certainly right about the C0 stepping. It requires 1.40v minimum to get it to around 4 ghz while stable. With each 0.01 voltage increase brings around 3-4 degrees higher in temps. This makes the heat management totally unbearable. I've already ordered an E8400 with E0 stepping. It can OC to 4 at just 1.24v or so which sounds a lot more reasonable.

well make sure that you have done some cable management because it can really increase temps just by haveing loads of cables hindering air flow. well you can fit any more fans but mabee you can set the fans at the top of the case the push the air out and the ones at bottom to air in that might help in keeping the hot air out and getting cool air in. other than that you could look at more powerfull fans.

Yeah I have cable management done (I use Corsair HX1000 PSU) which is a modular PSU (I only use the cables that I only need). The fans are fine too.

I've got:
- 2x 80mm silenX fans for 14dba ouputting 24 cfm (located at ram and vga areas)

- 1x Cool Master 21dba output 21cfm at the roof

- 1x Scythe S-flex 120mm 49 cfm 20.1dba 1200rpm at the front for intake

- 1x SilenX 120mm 73 cfm, 21dba for heat dissapation.

So really it's the setup within that's trapping all the heat 🙁

water cooling a possibilty or not?, otherwise get ure self some 100cfm 40db fans they will suck like you have never seen 😀. i have a few spare if you want some. 120mm

 

[Homeboy2]

Best bet is to cut a hole in the side panel and put a 250mm fan or a 360mm if you have room. Some noise but very low pitched, not objectionable, at least not to me.

When i get around to it im gonna build a case with much better airflow than anything you can buy at least among standard cases. Standard cases are laid out really bad for airflow. Nothing is finalized but it will prolly be a tall cube . first model with MB laying down. Two 360mm fans one intake, one Exhaust, at 90 degree angle with the vid card and hsf. Right angle adapters for dvi cables,rj45, etc. to get the exhaust fan close as possible.
Hard drives, psu in bottom so NO cable management problems. DVD burner in top with a Noctua 120mm exhausting at top.
The big fans will have a 12" tube in the middle to prevent turbulence and increase air speed.
Comments, suggestions? compliments? Curses? Flames?

Bet my ex gf can beat them!

lol but can she suck a golf ball down a hose pipe now thats suction lol 😀.

Well I have an old case that's why I'm left with these solutions but at that time this case does pretty well and I think it does pretty well overall even today. I have the Sunbeam Transformer case back in 2004 (It's almost 5 years!). I love it to bits though.
