Overclocking 3.0E D0

[JoeCentrino]

I just got this Prescott 3.0E D0 out of some dell system.

I have read Batboy's article on "Cooling a Presscott". Should I have the CPU fan and the fan mounted on the duct both blowing ONTO the cpu? or AWAY from it. And what about the fan I have in the back of the case? Should it be blowing inward or outward?

Second question is what case do you guys recommend me getting that is suitable for a presscott and would require the lease amout of modifications. I know there are tons of cases out there im just wondering if there is a specific one u guys have had experience with or seen that has potential.


Last question, what is the best Stepping for 3.0E presscotts?


Any help at all will be appreciated :)

Heatsink fans should always blow ONTO the cpu. Rear fan should be exhaust.

Whatever case you like, part of the fun is modding it :thup:

I tend to think the D0's scale the best, but that's just my observation, i have nothing to back this up besides owning 2 nice D0's, one of which was a 3.0E.

[JoeCentrino]

All this time i've hav the heat sink fan blowing the wrong way. It's a thermaltake i will get the exact model for you guys. Im not sure if i can change which direction it blows though. Has anyone changed the direction their cpu fan blows before?

[enduro]

All you have to do is flip the fan over lol :D Or is it attached somehow?

And yes people have changed the direction of their cpu fan's before but it almost always results in higher temps. Better to flip it over and exhaust out the back.

I got an ordinary SL7E4, DO CR from Outpost bundled with an ECS board for $179. It's knocking on the door of 4 gig at 3.97 at a tad under 1.4 volts, HC200. Didn't try higher before I took it out. I think it was a week 44 of 2004. Board is the IC7-G.

Not all sinks blow; the Alphas suck best, according to the manufacturer. What I do is suck and use a 90 degree shroud to route air to my exit fans at the back of the case. So I use a 120 mm fan blowing cool air at the base, it sucks this up, heats up thru the sink, and exits the case. Ideal setup for overclocking. Unfortunately you can only get the aluminum shroud in Japan.

Here in Japan, we have relays to run two PSUs. Just plug the second PSU power socket into this thing together with any 12-volt plug. A relay senses power to the ON switch and turns on the 2nd PSU. No need to bother with getting extension power socket cables, splicing wiring, etc.

What type of memory did you have due to I'm only able to get 3.86 :bang head

[illogical06]

I'm wondering the exact same thing as you DuctJet. I got the same prescott @ 3.525ghz but my ultra slow ram is holding me back. I'm not sure which ram will yeild the best results with my cpu and mobo.

I will be buying the 3.0E socket 478 from ZipZoomFly very soon. I want an E0, but I guess I can settle for a D0 if it will do fsb250 (3.75GHz) stable without having the voltage up to high. What are the chances of me getting an E0 do you guys think?

A 3.0E is only doing 264-265 at 3.97 gig, so you don't need fantastic ram at 1:1. PC4000 will do. TCCD also should handle this fine. Unfortunately, 264 is no-man's land as no way BH-5 will run 3D here, even if you had 3.8 volts.

The only sure thing is PC4000 at 2.5-4-4-7 or TCCD at 2.5-3-3-6.

The ram with the most potential here is Ballistix PC3200/4000, as yields get better with time. I managed 263, 2.5-2-3-5 with some real late PC4000 sticks but the IC7 just hates ram at 1:1 and 5:4. No way I can run that high on this board. I did that on an IS7.

A 3.0E Pressie at 3.97 gig, 1:1, 2.5-2-3-5 with 2x512s will give absolutely awesome benchmarks!

The HIGHEST 3DMark2000 score I have ever clocked on my five rigs is at 258x10, 2.5-2-3-5 on a S754 NF8 board and a 3400+ Clawhammer with 1MB L2 cache. I hit 27.6k. Best I could do with S939 and Winnies at 2760 is barely 27k. That's with Ballistix PC3200. There is no other ram in the world right now that will do those timings >250 fsb with 2.8 VDIMM.

MemoryExpoUSA has EO 3.0Es still, I think. OEM.

[betterlife18]

Ok I just bought the 3.0E/478 from ZipZoomFly for $180.50 (retail box).
My girlfriend is getting me an Antec TrueBlue 480watt PS for Valentine's Day :attn:
I REALLY HOPE THIS SUCKER WILL OC NICELY!!! :-/

[jtracc20]

i dont see why you shouldnt be able to hit 3.7. i did with stock cooling and stock voltage. ran prime95 for a few days. ran fine. no errors. but the minute i inch past 3.7 thats when all hell breaks loose and the random restarts start. i might one day push it further. i tried before on stock cooling and just upped the vcore but that didnt do anything still restarted. need some better heat desapation. will eventually buy a nice cooler. but i am happy with 3.7 right out of the box. :clap:

[betterlife18]

Heck yeah! 3.7 out of the box would be awesome. I have 5 case fans and a copper heatsink... currently my idle temps are 25-27c with my Northwood. Cooling shouldn't be a problem, I just hope I don't have to up the voltage too soon. What's the max Intel recommends, 1.4v right? If I hit 4GHz with 1.4v or less, that would be awesome.

[Clevor]

I tested my buddy's EO 3.0E: ran Memtest clean at 4 gig, but wouldn't boot Windows. I estimate 3.9 at least at default voltage.

I'm really happy with the DO I got from Outpost: $179 including ECS board! That's a retail chip. I plan to sell the board to recoup $30. I dunno, I may install it to check it out, but it's a VIA, and I bet no VCORE options.

Guys are making a big deal of a 3.2E at 4 gig but a 3.0E is sweet, tho' I'm on water. A 3.0E at 4 gig will actually outperform a 3.2E due to the higher fsb: 267 versus 250, assuming the same ram timings.

[betterlife18]

Yikes! I just found out my girlfriend will NOT be getting my Antec 480w TrueBlue power supply, so for a while I will be sticking with my 350watt :-/

Do you guys think this will be enought to push this Prescott?

I've got three hard drives, a FX5900XT video card, two optical drives, floppy, three 80mm case fans, and a Cooler Master Jet4 HS/F being pushed by the 350watt, I don't think it can handle much more, especially a Prescott :bang head

Whatcha think?

[jtracc20]

i'd say your pushing it but it will probably run. if you ever decide to upgrade that video card, you wont be able to run it on that PSU. esspecially the 6600GT and up., or 9800pro and up.

but anyhoo, the pressy is a great chip. i gotta tell you, i was a AMD diehard fan, but i have switched pretty fast after seeing wat this pressy did for me stock. i am happy. i tried 3.8 it runs, but not stable. 4.0G out of it is pushing it, but hey if you got water cooling then hey its completely possible. the only thing i am having trouble with, because i am fairly new to O/Cing i just got into it a couple years back. i am still not certain what RAM timings i should run. i am on auto right now, but i bet there are better settings for me to be running. i just dont know about it. wish i could read something and that would tell me :drool: :thup: :bang head

[betterlife18]

jtracc20, about your timings...

I have OCZ Dual Channel DDR500, and at 250fsb (1:1), 2.5-3-4-5 were stable for me. (Or was it 2.5-4-3-5?).

And thanks for the PSU info!

[jtracc20]

yea i dont know a lot about the timings. what you just wrote up there is just numbers to me. LOL!

i need to know what locking means, and for example i can lock my cpu @ 66/33. now i have no clue what that does. but i know if i changed my timings and could use more of my ram and hit a higher o/c. cause my ram is capable of much more i know it. right now my ram is at 400 fsb when it can do 500. so i dunno .. not sure what to do. need to read something, that explains what timings are and how they apply. then learn ho to get the best one. i just dont understand it thats all. is the 1:1 = 66:66? wat timing is 66/33. like i have no clue what that means. lol. when it comes to timings i am a newb.

[betterlife18]

that 66/33 you are referring to is locking the AGP/PCI frequency, not the CPU. Locking it keeps it from fluctuating. If you raise it, it sometimes can help in overclocking, but nothing that I've noticed really.

My 3.0E from ZipZoomFly should be in Wednesday. I really hope it does at least 250fsb on air with my setup :attn:

[jtracc20]

250 will be challenging. mines at 247. wont hit 250. errors. its rediculous.

cant believe thta 3more mhz is that big of a deal. lol.

i read a few things on the timings. so of course i tried it and nothing but failure. had to reset my bios a few times cause it wouldnt post. doing something wrong obviously. need a little more practise.

[betterlife18]

Have you upped the voltage any yet?

[jtracc20]

yea i upped the voltage, but i have stock cooling. i dont want to mess around with the voltage until i get some AS5 and better heatsink fan.

not worth blowing up the pressy for a couple more mhz.

[illogical06]

U don't have to worry about blowing up the pressie if you monitor your temperatures with mbm5 or an equivalent. Also, make sure how accurate (i should say how inaccurate) your mobo reads the temps because most are pretty far off. 69.1C is the highest intel says it can go but on stock, you can still up the voltage a tad i bet and be fine, just watch your temps.
