Overclock core i7 920xm

Hi guys, i'm italian and im new of this BIG forum forum!
I have buy a Deviltech Hellmachine SLI (Clevo X9100) with i7 920xm, dual gpu 285m gtx (SLI) 6 gb ram, Win 7 64bit.

I want overclock the cpu but the bios is a Phoenix Technologies LOCKED !!!

I have try to oc from software with EVGA E-LEET but when set all the multiplier of all 4 cores to 27x, my notebook see blu screen and reboot!

After i have try setfsb but is not good, after only 1 mhz freeze the notebook !!!!!!

How it's possible arrive to 4ghz whithout freeze the notebook?

Thank you for your asap respons.


Regards
Simone.

 

Its quite possible your chip may not be able to do 4Ghz. If E-Leet at least partially works, keep tinkering until you find the best compromise between speed and stability, not every chip is made the same.

 

Thank you for respons.
I dont pretend to reach to 4 ghz but at least to 3,6/3,8 and every person that have this cpu and apply an overclock, it's good and stable to 3,6/3,8.

It's possible overclock with anoteher software?

 

nope eleet or nothing

tbh you got screwed with a locked bios with a 920

thats killed ur chances before we even start

 

It's possible unlocked the bios?

 

The problem is not that the bios is Locked but i dont see nothing of fsb or multiplier in my bios!

From eleet for me its possible run so:

core 1: 27x
core 2: 27x
core 3: 26x
core 4: 26x

If i move the core up to this multiplier, crash the blu screen (i try all with FSX)

 

Those multipliers are too high. You are not going to be able to accomplish that with the system. You don't have anything in the bios that looks like THIS?

 

The bios in the image is the same of my but, in the Advanced section i have:

- SATA MODE SELECTION
- LEGACY USB SUPPORT
- BOOT TIME DIAGNOSTIC SCREEN
- POWER ON BOOT BEEP
- BATTERY LOW ALARM BEEP

That's all!!!

How can I do to the section "ADVANCED CHIPSET CONTROL"???

 

you cant is the simple answer.

Deviltech probably dont supply it. The only way to get it is from them.

They havent installed the BIOS with the overclocking features, its as simple as that

 

Can't he reflash?

 

It should be possible but he would lose his warranty then I guess even though the X8100 is intendet to be overclockable with the 920XM.

Warranty provisions are quite strict in the EU so propably they wanted to reduce their risk by deactivating the overclocking feature. On the other hand you pay a lot of money for the 920XM especially because it is overclockable and the risk if the CPU fails is not with the reseller but with Intel so the feature should be enable since you paid for it.

 

For warranty purposes he should be able to flash back.

 

I don´t think a successfully flashed bios will kill his warranty.

It will be an issue, when the system dies during the flash process

 

If it's possible i flash my bios and at the moment that i have problem with my notebook i reinstall the original bios. It's possible?

How can i flash the bios?

 

I could overclock via software without going through the bios, increasing the FSB and the multiplier?

 

you need to run a program called addfsb first.

 

This program tune up the fsb?
It's compatible with my mainboard?
when i download this program?

Sorry for this many questions and thank you for your help ;-)

 

it was a bad joke. The Core-i architecture does not use FSB because the memory controller is built into the processor. Your best bet for OC'ing is getting the better bios.

 

How can i flash bios? There is a guide?

 

he could flash the bios he would need to get someone with the unlocked bios (seeing as there is no public release of this, its only installed on machines with 920's at point of sale from vendors who support it)

so if he could find a way of getting it then he could install it

 

An user of this forum said me of downgrade the bios to a back version because my bios is new version of clevo bios.
But what version of bios i can download from this thread?
http://forum.notebookreview.com/showthread.php?t=416916

 

My bios version is 1.00.01 without oc option.

This version with oc enable it's good for me?

W870CU (Sager 8760)
BIOS 1.00.01 with OC
Dec 2009
Thanx to bratella:
http://rapidshare.com/files/319486371/W870CU01.zip
Has OC capabilities

 

I shall prepare myself for a load of lols.

 

Only if you had a W870CU so no.

 

Where i download a back version of x8100 with enable overclock option?

 

It's probably not a back rev, just a different one. I can't help on where to get it.

 

Ok...!!
It's normal that eleet have locked the qpi? i have locked the qpi and unlocked the multipliers! Why???

 

correct the bios revision is exactly the same, one has the unlocked options and one does not.

Simon,

I am going to put this as simply as i can

Devil tech did not supply you the bios.

They are the only ones who can

If you want it get it from them

We cannot help you, anything we supply could brick your unit.

 

The x8100 as far as I know cannot change the bus speed. You would have to get an Alienware (M17xR2) or Asus (G73) but even then it's still limited.

 

I have read that the back bios version (october) have oc enable.

The M980NU is the same my notebook, here http://forum.notebookreview.com/showthread.php?t=416916 there is the october version, i can install this or create problems?

 

No you cannot install it

it has a different mobo, different cpu, its totally different you cant use that bios

Simon if you want the unlocked bios you ahev to get through your vendor

 

From cpu-z, Mainboard section:

Manufacter: CLEVO CO.
Model: X8100
Suthbridge: PM55

I have send an email to my vendor for bios.
The seller may have the bios? In the case can be sent or you can refuse?

 

Getting the bios version from someone who owns the X8100 and has the bios version were overclocking is enable is most likely your only chance.

Otherwise, if your German is sufficient, you can complain to Deviltech stating that you paid a lot of money for an overclockable system and got a system which cannot overclock in which case you could have saved money and bought the 820QM instead. But I heard the DevilTech support is not that great - at least they were very misleading with the Mobiliy Radeon 5870 telling me in the end of January that they would be able to deliver the W860CU with the 5870 the next week which could never have been true or so they should have known.

 

they can refuse to supply it

devil tech never promised to supply it to you so if hey want to refuse they can and will

 

its dangerous and can cost them money since people like ^^ try to do it and brick it ...Then file complaints against them for not fixing their mistake.

Anyway i agree with resellers , I do not think the BIOS should be avaliable.

 

But that's exactly why you pay more money for such a system. As far as I understand the X8100 with the 920XM is meant to be overclockable so he could expect to get an overclockable system. The "overclockability" would be limited anyway so that you cannot go beyond a certain degree from which on it would be too risky. But to deprive you of what you could reasonably expect when buying such a laptop is a clear reason to return the laptop, at least in my opinion. They did not state that the laptop is NOT overclockable so it comes down to weather one could have expected that the laptop can overclock or not. When buying such an expensive product it is likely that one will make a little research and by research I just mean typing in the name of the product into google - everybody with internet can do that. Without much research one can find out that the DevilTech HellMachine is in fact a Clevo X8100 and Clevo's product page on the X8100 states:

It's also quite easy to find out that the key feature of the 920XM is the free multiplicator which allows overclocking.

I would have expected the feature to be enabled because that's what's reasonable. DevilTech propably just wants to save some work because a bricked system would fall under their guarranty agreement with Clevo/Intel anyway. But well, just my opinion and this is pretty much what the German law would be like in this situation and DevilTech is a German reseller.

 

yes it is a x8100 but you are not buying it from Clevo as they do not sell to the public

That website is not aimed at end users, they can add whatever features they like, doesnt mean the vendors has to offer them to the consumer

deviltech do not advertise the machine as overclockable...end of topic really, if they dont want to supply it they dont have to

 

One last question and then you can close the topic:
if a user who has the x8100 with overclockable bios and is priced given me, if I install it cause me problems with my computer or not?
In this case defects can safely enter the original bios.

 

it could cause you problems yes

and if it screws up it is very hard to fix

 

perfectly fine on your opinion but it not yours that counts. The Reseller can get a unlocked BIOS but they are not and Clevo very rarely actually releases a laptop with a unlocked BIOS

Like i said it is your opinion but doesnt't mean its going to be that way. Good luck trying to change it...

 

Just for the record there is an unlocked bios being provided by a few vendors, just so happens deviltech isnt one of them

more reaserch beore buying needed really

 

Can you tell us who offers the unlocked BIOS?

 

I know of 1 in the Uk (no prizes for who) but i think exotic offer it as well

 

kobalt, xotic, rjtech, gentech...all the common suspects I assume.

 

Are we talking all CLEVO models?
I'm close to ordering W860CU with a 920-XM and looking to OC it with E-LEET. nothing to crazy but still I want to OC if I want.
Of course through the BIOS would be better but not sure if that's a option.
Any thoughts?

 

it exist... but good luck getting it from a reseller

 

not all resellers will give it to you, as i said some do give it out. However its very much a case of pot luck.

some retailers more willing to give it out then others.

 

This might be harder than I thought.
Never used the E-LEET OC software anyone run into problems using it with a mild OC.

 

Weird, I wrote the DevilTech the other day to ask them if they deliver the X8100 with overclockability or not and they told me that they do not have the i7 920XM yet and therefore could not test if overclocking is possible or not. I'll ask them again in a few days.

I also gonna write mySN and ask them if their X8100 is overclockable or not. Before buying the W860CU I was thinking of buying the then upcoming X8100 and would have been disappointed if it would not have turned out to be overclockable. Also going to ask mySN if they can give me some some bios version where overclocking is enable in case I wanna buy the i7 920XM or 940XM sometime in the future.

 

OK, sorry for double-posting but this is great news. Like I said, I asked mySN if they offer their X8100 bios version with OC-ability. They gave me no answer to that question, however, they said they can put the bios version with OC-ability on the notebook when you ask for it. Unfortunetly they will not send the bios spereately. If you want it after you bought your laptop you have to send it to them and let them install it. Sounds bad, but this means that you will not lose your guarranty or take any risk.

I also asked them for a W860CU bios version with overcloking ability and they said they can get that, too and install it for me. I'm not in Germany right now but once I'm back or near Germany and considering buying a i7 920/940XM I'll definetely send it to them and let them install that bios version.
