M15x FSB Overclocking (not only 920XM!)

I just checked my one month old M15x and it also has rev 11.

 

I'm at work again... but when i get home i'll check mine also.

I think i remember Mr. Pras saying that it has worked and not worked with both revision 11 & 12 motherboards... so i don't think thats the problem... i wonder what's causing some to work, and some not to.

 

The rev. motherboard isn't the problem. It's just which pll the used on your board when they manufactured it. I'll probably tear mine down this weekend to see which one I have. More than likely those of use that it doesn't work on have the same pll. I don't see them using more than 2-3 variants.

 

So what's the working PLL number?

 

Would it any help to open mine up and share the PLL cause I don't mind. Have done it a few times already just don't wanna waste my time
If it's not worth it

- remember my PLL didn't work

 

If you want to and know how to find it you'll save me having to do it. I'm so lazy.
Here's kinda how to find it http://www.cpu-cool.de/FSB.HTM

 

It seems like none of the 820QMs have worked...

 

Good thing i traded my 820 for a 720 with my friend a couple days prior! Worked out in the end

 

Lol. Now I wished I got the 920XM. :S

Was only 130 bucks more.

 

So i took it apart.. I'm looking at the MB and I cant find anything. The link says it should prob be near a crystal but I can't even find the crystal.

 

judging from past experience, the only way to unlock multi's on non extreme processors is to physically short/cut bridges or pins on the cpu itself.

 

ahhh ... so scratch that then.. im not willing to do open heart surgery on this thing.. i7 @ 3.2ghz will have to suffice

 

I think I found the PLL on my MB.

 

wow, nice camera

 

Canon powershot G9.

Gotta love my baby DSLR

 

really nice photo +rep

clear as day on my screen

 

wow greatest pic ever posted,lol +rep

 

Look through the hunt for pll thread. Moo shows where his is in that thread. you posted a pic while I was typing.

That's it I believe. Have you asked abo about it yet?

 

I already e-mailed abo and he said that he doesn't have the datasheet for that PLL.

I did some research online and e-mailed a few people to see if I could obtain the datasheet so I can forward them to abo. Lets hope this works.

Now im wayyy to lazy to put my M15x back together... Poor thing is in peices on my desk.

 

maybe something will come of it.

 

Guys with the overclocking going on. Do you think it's the RAM that's become unstable @ 160, or the CPU itself? I'm gonna buy some 1600 Hyperx ram if the RAM is bogging the overclocking down. That is, if my 820QM can overclock when I try.

 

I don't think that's the issue since most people are using 1333.

 

I guess new 1333mhz ram should suffice then.

 

another M15x i have acess to wont work either and I cannot find what revision mobo it is

 

Did you look on CPUz?

 

well i have a revision 12 btw

 

i got rev 11 and it OC's nicely... but keep in mind the rev. doesnt have anythign to do with it apparently..

 

abo has updated his app setfsb

included in the patch notes:

i don't think so either, my theory is it's the pci-e bus.
i believe they might be linked.

when i pushed too far, i got a bsod, i noted that it refered to the nvlkdm driver.
upon reboot, i was greeted with a blank screen and my caps and scroll lock were blinking while numlock remained solid. after a bit of searching through these forums the best info i could find was this http://forum.notebookreview.com/ali...hing-scroll-num-lock-stay-bios-post-code.html

look at the image in post #2 by batboy (tyvm btw i couldn't find that anywhere else including the sm)

it leads me to believe they are linked and the pci-e cannot handle the oclocked speeds. now to figure out a way to unlink them if possible.

*edit* sorry for the double post

*edit2*
if anyone can find a program which will let me check pci-e speeds (in hz) that would be great.

one other thing, by unlinking and downclocking the ram in bios, overclocking hangs at overclocked speeds which are normally stable.
the more i stuff around with this, the more confused i am becoming.... arrrrrgh! also being unable to set ram timings manually... sucks bad!

 

For those that it doesn't work for have you reset your bios back to factory settings before trying?

 

Yes. And, reflashed bios anf, Full os reinstall. I tried just about everything.

 

could someone post a link for bios A05 please thanks in advance

 

i'm uploading it to sendspace as we speak for you shouldn't be too long

All done

http://www.sendspace.com/file/cuw7tx

 

thanks bro just bought myself an external as i need to reformat my comp to dual boot. So once ive got everything redone or before i put the osd and CC on ima change the bios back to A05 from A06 and hope i get better gpu temps.

 

wait what? why you formating? to get your cpu to OC?

 

no im CS(computer science) Major so i need to put linux on my machine as well as win 7

EDIT: ok so ive completely reformatted and now have dual boot and will flash the bios back to A05 tomorrow and we shall see if i can OC once and for all

 

well am going to donate right now... but isint there any side effects :s with SETFSB.... cuz ive got i7 720qm with ddr3 8gb 1066MHz? is it fine ?

 

Only side effect i know of is snappier, faster performance

temps haven't increased by much.. . maybe 2degrees?

 

btw i already donated for abo... but the problem is when i downloaded the setfsb it want start it will just show a box written in it SETFSB ID :...... dunno what to do?

 

he'll send you an email asking for your id , chipset, computer , etc,. then after you send it he'll give you your key.

 

man am lost he sent me message

examine the PLL data. I will examine whether it is possible.
1) start SetFSB.
2) click "Enter" button. (SetFSB ID screen)
3) click "OK" button. (SetFSB error screen)
4) select the clock generator to "PLL diagnosis".
5) click "Diagnosis" button.
6) click "Get FSB" button.
7) click "Capture" button.

but i didnt understand :S i downloaded the setfsb the shareware not the freeware after i install it it a double clicked SETFSB ... daah it didnt open anything just small box inside written inside it SETFSB IT ,,, am lost what does he want from me right now?

man , need help am noob !!!

full instruction from the begening first i download the shareware

is that right?

seconde i donate?

third he sends weired emails i didnt understand anything so guys help me with full instructions plz

 

There ya go.. just had to spend the time looking through the pages... annoying i know...

but i did that for you.... so you don't even gotta look for it

And since you got an i7 720 like me, move the slider to 492 (or 150mhz) ...as this is extremely stable and safe.

 

To my fellow people,

I was able to obtain the clock generator data sheet for the other PLL on the M15x Motherboard.

I am sending this information to abo ASAP.

Lets hope this works so we the rest of us can O/C our processors

 

Thank you so much! let me personally know if this works. I'd love to give abo his money back since he refunded me.

 

thank you titan god

 

Does this work with the 620M or am I gonna have to wait more?

 

it will work if you have the same PLL

 

It looks like your current ram is 1066, pushed up to around 1500MHz, that would certainly fail. I guess..

Rep++

Nice one!!!

 

Yeah, so I'm gonna get some 1333 or 1600mhz ram. But from what inap previously said, 1333mhz would suffice, so I'm probably gonna get 1333 instead of 1600mhz.

 

Updated first post to include JStarnino's info and updated the notes.

Yeah, I heard that 1600 doesn't really help or even doesn't work so well.

http://forum.notebookreview.com/alienware-m15x/499964-kingston-hyperx-ram-problems.html

 

Let me see if I can help with the memory questions....

The speed of the memory 1066, 1333 or 1600 isn't going to make a difference in OC'ing. If you are playing with the timings of the memory then it can make a difference.

The 1333 version of the HyperX memory comes in a non-XMP flavor. This means the advertised timings you see, you actually get without the system needing to support XMP profiles. This works great specifically for CPU and memory benchmarks but can have a large negative impact because of the additional heat caused by the tighter timings.

The person in the other thread has bad memory, not incompatible memory. I currently own 2 M15x system, one with HyperX 1333 non-XMP and one with HyperX 1600 XMP memory. They both run fine but when it comes time to benchmark I use my 1GB Elpida 1066 memory. You get better timings, less power, less heat with those sticks.

Hope this helps.
