x2 4400+ Core 0 no like to O/C

With my FX-55 I boot windows fine at like 2.8

lambusser

our system are very close, same case, powersupply, and watercooler. except i run sli 7800 :-) and only 1gig of ocz 4800

4 hours strong now, time to let'er burn overnight and hopefully in the morning she'll still be going.

If I wouldn't have checked out this thread tonight I might not of ever removed that damn IHS and kept on thinking I had a bum x2, tommorow I think I'll try pushing it on up to 2.8ghz instead of trying to lower the voltages! :D

Its still amazing to me that my load temps dropped a solid 15C!

Welcome to club of uneven core :) I am so tempted to take my heatspreader off but I am on phase change so cracking on core might be... bit easy.

Oh my god, you people are making me do this to my X2. Perhaps someone can do a simple guide on this with pictures? That would be much appreciated.

Thanks.

Take the thinnest and sharpest razorblade you can find. And cut around the IHS. Start with the corners then the sides. Cut often but gently. This way you can always try if you can lift it up already and be sure not to damage anything.

Yeah but thats hardly amazing since stock is 2.6... :p

you think this would work?

There is some more information here.

Hmm.. ok. Maybe that won't work then. I will have to go out and get a really thin blade.

EDIT: Just ran out and got these. Wish me luck! :slobber:

Yikes - lapped his core by the looks of it..

How do you know how much each core can take?

Prime95 can do the job.
I some prog. you can choose which core the prog. have to run on

Okay, I just did it. Previously 2.6ghz wasn't possible on this board (MSi Neo2 Platinum). And it is running 2.6ghz and running prime so far without errors (15mins) without the IHS. Amazing. The thermal compound that was in IHS was hardened, maybe solidified? And as you see in the picture, the compound wasn't completely spread on the die. QC issue, perhaps?

Temp has dropped 8-10C approx.

EDIT: I just bumped it to 2.7Ghz using clockgen. Prime runs fine!!! Temp @ 48C. This is incredible!

EDIT/2: I've tried to set it to 2.7ghz in BIOS and won't boot windows. Tried 2.6 and will crash at bootup. However, if I boot 2.5ghz and overclock using Clockgen, it will work fine till 2.7ghz?!?! Could this be Bios problem?? (MSI Neo2 Platinum v1.9 NFM modded bios)

Hm that sounds really great! Anyone running a decapitated X2 with phase ? :slobber:

Edit: h4nc0 make sure you read the clocks with CPU-Z in windows

Yeah, I did that. Clockgen set 2.7Ghz is prime stable, but BIOS set 2.6ghz won't even boot Windows. :confused:

Almost 16hrs of dual prime goodness at 2.7ghz, hasn't missed a beat! :D

i have just take the IHS off my 4400+.
and the load temp are drop to 52C from 60C. so it give me 8C.
but i am not sure. the temp on my Dfi nf3 is jump up an down all the time.
for now it is from 18C to 48C .so i say 48 C is the temp.
maybe there is a bios update for that

Sounds like you have bad contact with core.
But 18c sounds to low, try other bios.

I would like to know also, since i am awaiting on a unit and would either get

this chip or just jump on an FX57.

I have a Dfi NF3 ultra D. there is 3 bios 602. 705 and 711.
i have testet 602 and 711 and 711 dont work werry well.
i win and bios my vcore is 1.58 to 1.60v i now the board undervolt.
idle temp is somewhere between 20C to 40C.

Edit.
I can only use 602 bios . 705 and 711 lock my fsb at 269 mhz.
This board is asap on it way to DFi for rma. i dont wont to fry a $740 cpu in a motherboard that dont work.
is the msi neo2 work with a x2 4400+ cpu ?

am I missing something or what? its been sid that maybe there wasnt good contact with one of the cores, but the naked pics of the X2 I have seen make it look like its just 1 big core, not 2 separate ones.....

explanation??

you have right about that . is one big core.

... which includes 2 cores, because it was planned that way from the beginning of the K8 core. Not like Intel, who just put two seperate cores in the Pentium-D with some crossbar switch.

Its not that hard to understand and nobody said there where two physicaly sepearated dies with the X2's, not sure where you got that.

A quiz for you, why is it important to spead thermal compound evenly, is it true that the X2 have two processors on the same die side by side, if so what happens if one side of the die has better contact than the other?
