Cooling an e7400

I'm buying the parts to upgrade my machine and I plan to OC my c2D e7400 i just purchased and now i'm looking for a decent priced cooler for a nice solid OC. I haven't found many documented attempts or info on OCing this particular C2D so any other help you might want to offer will be welcome. I'm holding off on order my mobo till i come to a decision on the cooler so as to only make one order from the egg. The mobo i will be getting to pair with this e7400 is Gigabyte GA-EP45-UD3R LGA 775 Intel P45

Are there any notable performance difference between the s1283 3 heat pipes and the s1284 4 heat pipes xigmatek Coolers?

I was also looking at the Asus Silent Knight fry's has it in store this week for $39.99

One other consideration is Thermaltake's Big Typhoon which is $44.99 with free shipping @ the egg right now.


I'm trying to stay under $50.00 shipped/taxxed.

I know i will need the retention bracket for the 2 xigmatek's

Any suggestions on other coolers or any info about OC'ing this new toy are welcome. I have read the stickied thread about how to oc your C2D.
 
The board should give you a pretty good OC as the FSB appears to be able to go to around 500Mhz?

(glanced at reviews... :p)

As far s the coolers go - just look for some reviews, though the 4 heatpipe Xigmatek looks alright. But look at reviews of the 4 first. Also the $3 difference between the 3 and 4 heatpipe versions is kind of negligible.
 
that was my hopes with this board was somewhere close to the 500 mhz mark. and a 10.5x multi on the cpu i'm hoping to make the 4ghz club on air so i'll let you know if i'm successful.
:D
 
that sepecific thermaltake big typhoon will not be able to cool the e7400 with overclocking.. that specific ones really designed for single cores.. you want the VX version with the 1800RPM variable fan speed control.. but i wouldnt recommend it for a 4ghz overclock on that cpu.. id go with the s1284 out of that bunch..
 
Well the 1284 does it. I'm sitting here typing this on my new toy.

GA-EP45-UD3P
Intel Core 2 Duo e7400 @ 4ghz (400x10)
OCZ DDR2 1000 Platinium Edition 4gb (2x2gb)
HDT-S1284EE (with bolt through kit)

and this mobo is EZ mode for this OC all i had to do was turn off all the CPU throttling Stuff and crank the bus up and the multiplier down a half notch.
 


I'll get on doing some orthos and shit later. I'm not sure if this is 100% stable seeing as almost everything is on auto and i'm getting a little studder her and there but it could have to do with the rash of stuff i'm installing right now as well.
 
Okay i'm not sure if this is a dumb question or not, but i always heard the only dumb ones and the ones you don't ask.......

Is there any difference in 4ghz

I can get this chip to 4 Ghz a boat load of ways and they all 4 hour blend prime stable so my question is this.

Is 500x8 any better than 470x8.5 or 445x9 or 425x9.5 or 400 x 10 or my current 380x10.5?

It will post as high as 4.7 Ghz 495x9.5 however it won't do much more than post anywhere between 4.7 and ~4.0 i want to try and figure out a nice solid every day OC so that the wife doesn't get pissed if she wants to use the box. Once i have that i'll see if i can creep up any past 4Ghz with a stable oc.

Thanks for your input.
 
personally id keep a 1:1 divider by running a 400fsb.

you may see some minor performace increases by running a high fsb with your memory in 1:1

500fsb = 1000mhz for your memory. more bandwidth there but at the added cost of putting a lot more pressure on your mobo.

try each way and see if the extra performance is worth it.
 
The S1283 is the better cooler, as the S1284 does have one more heatpipe, however the heatpipes do not come into good contact with the IHS (as they are more offset), which is why the S1283 is the better cooler, cheaper to.
 
In trying to better this OC and find one the max OC for this box where do i find on intels site the max safe cpu Vcore?
 
1.4V is probably as far as you want to go, as once you go past a certain level the heat rises up very quickly and the Mhz increase becomes less proportional to the CPU V increase.

Nice OC though!

Also - what PSU do you have?
 
Couple more questions in my bios right above the CPU Vcore setting there is a setting called Line-Load Calibration with 2 settings enabled/disabled. Enabled says improve vdroop directly; disabled says follow intel spec. Which setting should i have this on when trying to OC?

also which Core voltage do you go by when people said don't go above 1.4v the one in the bios that you set it on or the value that you read in CPUZ?

Don't know the settings you mentioned.

As for the 1.4V, I guess to be safe use the BIOS values as I'm not sure exactly how vdrop occurs. Either way - you have a very good overclock there! And thanks for mentioning the PSU.
