i wonder why??

4.0 is max on average.

4.2 is if you get lucky

4.5-4.7 will require medium to upper tier water

5.0ghz will require a rosary for a good prayer and a dual cascade phase unit.

You talking about the E8400? 4GHz is standard, 4.5GHz is if you get lucky.
Yeah i've seen 5ghz on air but i will consider myself lucky to compelete 8hrs orthos at 4.5ghz on air


edit: best i've seen so fair is in your post over at ocforums ghost, 4.5ghz on air orthos for 6hours

Ah 4.9GHz, and only Super Pi stable. The E8500s seem to be ocing 200MHz higher than the E8400s, but they start 166MHz faster.

Well I just flashed the BIOS on my DS3L in preperation for my E8400 which should arrive friday(board came with F3). I figured it would be a piece of cake, but boy was I wrong. I borrowed an E6750 from a dell at work. That part went fine, was very easy to get the CPU out, no issues.

It should have been easy to put into my new P182 with my Tuniq tower since I had used the card board on the back to make the bracket tight against the mobo. Shouldn't haven't to take out the board right? Worked great except there is no way to put the screws in on the left side. My fingers simply don't fit. So... out comes the board. Once out it wasn't too bad putting on the Tuniq of course, though getting it back in was a tight fit. And then there was the 4-pin power connector on top of the board right under the tuniq, grrrr. Had to reach my hand through the tiny hole in the back of the mobo tray to get it in. Making me regret buying this cooler since i'm going to have to do it all again when my E8400 comes.

Oh but it doesn't end there. Got everything hooked up and running and tried to flash to the f8a bios. Don't have a floppy but the manual says a flash drive will work fine. So I put in the flash drive and go into Qflash. Sees my flash drive, yay. Cept it doesn't see any file in it. Was able to save my current bios to the drive and see that, but no .f8a file. Tried another drive, still no go. Made sure it was fat32, it was. Reformated it a few times. Tried f7 bios, same thing. Finally tried regular FAT for the hell of it, and it sees the damn file! So I try to update to the f8a file, get a Checksum ID Error. Son-of-a!! Updated to f7 just fine. Re-download the f8a bios and try again, finally works. What a royal pain in the ass!

Just thought I would share for anyone else who will be going through this.

Oh and one question and the CPU fan speed. What is the best way to control it, use the manual knob that came with it, or use speedfan that came with my mobo?

I bolded the important parts to re answer your question.


Okey let me clearify. Medium / Upper Tier water means:

A strong pump usually only in a CPU ONLY LOOP. Upper tiers are mostly dual loop systems.

A good block which uses a form of accelerators to speed the water over the cooling area in the middle. The 45nm blocks are smaller and have less foot print in the heat it dishes out. Having an Accelerator nozzle focusing on this little area should give you awesome cooling.


Lastly dont underestimate water expecially on single dies with small foot print. Anyone know if the IHS's are soddered on these guys? Im curious in getting one just to drop my storm on and see how well that thing would do.

Ugh. I'm going to be trying this process with a p35-ds3p and my actual e8400 that's not supported by the current bios, so I'm sure it's going to go much smoother :confused:
Wish me luck

Hmmm... Easy 4 GHz AT STOCK VOLTAGE? Wonder if Intel is watching this stuff and getting annoyed they didn't speed-bin faster chips for more money. Looks like they actually could create their first 4 GHz SKU.

I'm doing very well with what I now have, I wonder whether it's worth the trouble (you know, yanking the board and HSF, swapping, possible BIOs update, etc...) for a prospective 400 MHz speed increase. The 8400 and 8500 do have higher multis, though. Maybe I'll just go for a 1333 quad in a while. Don't think I want to disturb a system that hit 15 hours Orthos stable, not for awhile.

Hey VirtualLarry, thanks for the idea.

Here are my 2 system scores.(cEM/SEC)

x2=3164660 cEM/SEC at 52% cpu usage on both cores. set affinity to 2 and priority to high
e8400= 3922160 cEM/SEC @ 90% cpu usage on one core the other seems to be running at half of the first. set affinity to 2 and affinity to high.

I tried changing them to real time but it didn't seem to make a difference.

Not sure what these mean but if you have a clue please let me know.


Heres the results from something unorthodox.

I ran 4 instances of the progy on each computer at the same time
these are the scores from each test

x2- 894768, 786104, 826246,2140778 = 4647896 CPU 100%

E8400- 1289418, 1227761, 971221, 899679 = 4388079 CPU 100%

That even makes me more confused
also the matrix rip was from dvd disc drive.

watch out on that board!

you need a relative high VCORE to get high oc's on this chip from the looks of it.

That board has issues when pushed higher then 1.4Vcore. Just a heads up.

I had heard about this problem before but thought it was only for the ip35-E. Is this problem common to all the ip35 boards including the Pro?

100% sure it's soldered. Not too long ago I attempted IHS removal on a $30 Celeron and it was soldered. Ripped the core right off the bottom PCB. At least I got to see the beautiful rainbow reflection on the bare core.

u better bust out a screenie of this otherwise its another overshoot claim.

And it wont prime i bet you.

MAN! i hate doing the 4 razor trick. I f'd up a quadcore doing it. Lucky for me it was a crappy B3 X3210

dam..... someone hasnt found a feasible way to get the soldered chips off yet? other than a heat gun and some luck i dont think its going to happen.... although lopri that is kinda cool :p

I haven't tried it on a intel chip.
But on amd chips you cut the epoxy very gently around the IHS, heat it up with a hair dryer, then as quick as you can twist the IHS slowly. When it starts to give a little force back quit and throw the hair dryer on it again and repeat. Once the IHS has turned about 75% then heat with the hair dryer again and instead of turning, this time gently lift from an edge with a razor blade or 2.
I wouldn't advise it tho. I never got a significant increase to justify the effort.

on AMD Opteron /w storm.

Gave me around 8-10C Thats why i want to try. :D

Thats with my 7900GT's on the same loop burning up from RTHDRIBL. :p

Dayam i wish i had pictures of my storm.

But heres what i mean. If the IHS is off, the base on a waterblock is usally really thin.
So imagine having jets like these: (the silver plate in the middle forces water to move faster)

http://i125.photobucket.com/al...aigomorla/IMG_0842.jpg

close up of the jets plate:

What i mean about really thin base:
http://i125.photobucket.com/al...aigomorla/IMG_0844.jpg

Cooling that tiny little die. :T



Almost tempted to try....


PS: i just showed off the EK Supreme if anyone is curious.


Once again.. dont underestimate water.. :T

Something was wrong with my board. Last night I placed the two systems out on the porch and ran the cables inside. It was 3 degrees outside. Wind chill had to be -20 or lower.
Played with them both and had fun.Its amazing what extreme cold does.
Got the E8400 upto 1.41volts and managed a 4.5ghz overclock.
Then I heard a loud pop, more like a pistol going off , and the e8400 system died.
Brought it back in and 2 capacitors had blown out. A small one near the memory and a large one near the back of the board.
I also noticed that the memory sticks were cold. They should have been at least warm.
Performance was most likely being killed by the board. Think I will try another board and stay away from Gigabyte.


Aigomorla,
Nice work with the water.

I don't know about these, but back when I used to test Microcontrollers I used to saturate the connections with flux, and heat it up with a heat gun while pulling with tweezers. It would usually come off after a few seconds. Be careful when you are pulling though, you don't want to leave any pins behind. Clean the flux off, wash off the cleaner, let it dry (use the heat gun on low to quicken the process) and viola.

E8400= 17 sec

Liar.

PWNT. x2 would be like 40 secs and e8400 would be like 11

Sorry but I dont get the glee. :confused:
Correct me if am wrong, thot the guy was asking for help with the anomaly and seems the motherboard was the culprit

I think they are alluding to that the claimed SP1M times are what former Pres. Clinton would call "factually incorrect" (but much better than his "I engaged in conduct which was not correct" apology, but I digress). Perhaps I would not use the term "liar" in this context, perhaps "foggy memory" would be more appropriate.
