*Official* Alienware M18xR1/R2 CPU Overclocking Thread - Learn How and Share Tips Here

sorry that happened. No one told you to use those settings in that particualr pic... the pic only was to show you "advanced cpu control" is the right menu in the unlocked bios that when you adjust the long watt limit it will aloow up to 99 in that menu and only 80 if you go to the location of the stock bios overclock menu... you know the one where you can set the baseclock? If you go the the menu where you set the baseclock the highest long limit is 80watts but in "advanced cpu control" you can set 99watts like the short limit. Sorry for the confusion and in all cases of what we have been talking about adjusting... taking the laptop battery out and removing the ac adapter and removing the cmos battery power on the system with no cmos after the beeps shut off and replace battery and cmos battery and your good to go...this will fix almost any prob we will run into unless you flash a bios incorrectly and its usually very straight forward. Stick to the suggestions... I don't suggest enabling hardware cpu id limit as I have had the same results. disabling virtualization is not necessary and completely up to you... if you aren't going to use a virtual operationg system then you don't need virtualization on... but like I said it's not hurting anything either. Guys if I can manage a 32m wprime run at *threads 5.0ghz can we then say that's the highest we know we can go quad so far? Obviously I don't mean for real world use but as hardware limitations... I will need to do it on AC in next day or so... but my pic from previous post was for s few seconds and without anything but a poorly designed notebook cooler Zalmon NC-3000 and fans at max which is how all my benches except for one I haven't posted have been done. The 167sec wprime i'll post later was on the ac. I got 168 lowest without AC. But as for being able to use the chip in 8thread usage 4.6ghz is really near the max thats realistic. I have had a few 4.8ghz and a partial 4.9ghz 32M run on wprime at 8threads. Do you guys want any pics of the 4.8ghz quad or the partial 4.9ghz? The 4.8 was 8threads 100% and the 4.9 not all the 8threads were completely 100%. So i don't need an answer on all of these questions but I want to know opinion of the 32m wprime 8thread that I plan to run at 5.0ghz. BTW the intel processor ID utility puts a light load on the cpu much less than wprime, prime95 and intel burn. So if you guys want to check ultra short term quad core peak speeds while your trying to hone in your overclock try intel processor Identification utility to see whats going on... Thanks guys just wondering... haven't had many responses.
*****************
Johnkss thanks for helping get Side-Swipe back in order. You've been giving everyone great advice. It's all coming down to all the same stuff its been all the long temps, amperage, voltage and wattage.

 

even at 37 and throttle stop temp at 90 it cuts back to 3.5 final time was 258.734 with everything at 37 and throttle stop at 90

 

I've been able to run 37x on 1024 prime all through the test with flex @ 0 and Pri Plane @ 600, temmps never go above 88

 

in my experience there is no magic number. I have tested up-to 2400 not sure if anyone else has been in those ranges yet... and as long as I don't raise watts to high I have not had ill side effects. From my observation as amps are raised it allows the watts you set to actual show up and the chip operates at them more and not as low as when the amps were at 97. So for me I've gone to 2400 in bios equaling 300AMPS. This could be deadly to all the inner electronic connections as these systems were designed with a specific set-up in mind. So if I go from a majority view 97amp to maybe 130amp is the most you will need. I'm crazy don't follow me I like to push things as far as I can...(5ghz 8thread)

at 300amps instead of 99watts long I found 81watts to be more in my long-term thermal headroom. But around 112amp the 99watts long-term seems just fine.

 

I and Johnkss.. may be more excuse me if I am wrong have gotten 4.6ghz 8thread 1024m wprime runs. I am saying this just as reference so you know under best cooling scenarios its about the max for a laptop heatsink (unless someone tries dice). We both used hw-info to max our fans out and i am repasted with ICD24 not sure if Johnkss is repasted or what he has repasted if he did.

15flex is sufficient to survive a wprime run at 4.6ghz. You can try 12 flex and inch up if your not scared of bsod's. if its like 0000000124 0r 0000000101 they are common for needing to increase you cpu voltage-flex. john what did you use on your 4.6ghz wprime? if it was a low flex its because you kept yours cooler than mine was during the run. As temps rise the cpu requires more voltage and adds it necessary till it hits the max vid and when the cpu requires more it crashes unless you add more voltage(flex) or throttle it yourself some how ie long and short time limit helps that scenario allowing high speeds for short periods and then drops to your long limit... so your long watts need to be able to survive anything and not shut down because of your temps. Actually it was a 4.62ghz at 15flex so go up from 12/13 to as high as 15 flex. Go to "my computer" hit properties. Go to advanced system settings and under "Start up and recovery" and "System failure" uncheck "Automatically Restart". This way you can see what BSOD code the system posted instead of it flashing and restarting or it may be set to make a dump of your memory to a file before its shuts the system down in which case the bsod screen could show for a few without uncheck automatically restart. Just hold the power button for 4seconds when your done seeing what code it was. A few posts back I showed common overclocking bsod codes.

 

Right Johnkss helped me get super stable at 46x it runs a whole 32mb Prime, the issue is that anything past that and I can sustain it with my temperatures. We conculded I need to repaste big time to continue the tests. I'm sure he's going to want me to try 47 eventually.

At this point and while I wait for the repaste, I'm trying to find a scenarion where I can run 40x all around a Wprime95 withouth extended custom cooling the magic number in my M18x seems to be 5 flex 800 plane. But it does touch 90's then the throttling kicks in at atound 60%.

 

32M I can get 4.8-4.9ghz not just 4.6ghz I am repasted with Innovation Cooling Diamond 24, I posted 4.6ghz 1024M. I am when I have time going to try for a 5.0ghz 32m wprime. 4.7ghz for 1024M would be cool. But for 32M we can definately go much higher than just 4.7ghz on the 32M test. nice work thus far... these are amazing chips right?

I can boot to windows with 50/50/50/50 on the multipliers and load a tiny 8thread load at 5ghz. My super Pi runs are at those turbo multipliers.



wprime 1024 8thread 167.016 secs 46x 100.9bclk 4638mhz 116 long and 117short 128tdc 15flex

this was on air conditioning... my only bench on AC. 167secs... and without AC the lowest i've squeezed out is 168secs.

 

Nice! Would be nicer if you could run 24/7 and game at those clocks

 

The funny thing is you wouldn't see that much improvement in game performance...

 

Very Impressive RV.

When you say AC, do you mean sitting the laptop in an AC vents? I'm thinking that's probably a better idea than a freezer due to more air being pumped in.

 

Thanks Xeneize. Yes that's exactly it on my 167.016second run. But it wasn't long that i had to tinker so there could be more to be gained... but as reference I got 168 with regular air cooling (a Zalmon nc-3000 with the m18x raised maybe a half inch away from top/ back of m18x on the notebook cooler since the fan isn't over gpu's this allows full air flow from the cooler and cooling doesn't before hand with fans at max and and I lock my multi at 8x until i start the bench to keep the cores extra idle. Also Johnkss got 167seconds too not sure what his cooling was.

 

Yes the 5ghz runs i've been trying aren't good for anything long term since the temps skyrocket the second you put a load to the chip. It also requires rather unsafe voltage for the SandyBridge line even higher than a desktop would desktop sandybridge to get to that range. Johnkss or someone with a 2600k what does your chip require in voltage id and amps and watts to get to the 5ghz range sepecially quad core 8thread range? Preferably air-cooled estimates since these chips aren't liquid cooled lol. I seem to be able to manage 1 to 2 core 100% or 4 threads 100% all at 5ghz... but as soon as I attempt it at 8threads I drop to 4.5 then 4.3 right away. I'm back tracking to the 4.8 to 4.9 range and I'll go up from there to see where it just drops from ... like if 5ghz 8thread won't run then maybe i can identify whhere its going down maybe it's around 4.95ghz range? Mind you I'm speaking a bench as long as 32M only.. in 8thread.

*************************************************
on the side as a separate project i've been working on a 4.6ghz quad to anywhere's from 4.7-4.9ghz single core overclock for gaming... that would be in short limit on the cpu and if there was anything as stressful as intel burn or prime I will have my long watt limit programmed to safe levels so under worst case scenario my laptop could turbo boost but keep under the thermal shutdown temp no matter what... so its just based on length of time for short watt limit and the amps you set with whichever watts you set for short and long limit. Always stress test before setting clocks to be for gaming in the long term.*But if you set you short watt limit to the outer limits too this also could some day cause a thermal shutdown since turbo boost would take your temps right up to the shutdown.

 

eh......a stupid question
how to set the core ratio above 45 in the unlocked bios？
in my bios the limit is still 45 45 45 45
when I try to set it to 46
it go back to 27......
thanks~

 

You just have to use "hex editor" and set the multipliers you can set as high 50... haven't ever had it successfully set higher. I wish it went to 57 like the 2600K it was posted under A03 bios editing via Da_g's Method

 

So I cant get that 37 across stable wat should I do?

 

The problem is when newbies like us try OC'ing, they miss two key points - proper TDP/TDC settings and of course Temps. If your ambient is 25C + and you don't keep the system on a coolerpad, elevated, etc, - you won't be able to push it above 3.7stable unless you raise the throttling temp, up the Long and short duration PWR, up the bus and keep the Flex as low as possible. I don't feel comfortable about pushing my CPU above 90C and am not interested in keeping my system apart/in a freezer/etc, so I'm staying below 4.0ghz untill a better heatsink is ready...

 

This is what I recommend... I have been able to get a very stable 38x to 40x

For 38x try this:

Set all the Multis to 38x
Set your Vid to 0 (zero)
Ser yor Max and Min power to 99 and the time to 56

Then on the Power menu, under CPU set it to 800

Also make sure that on the Thermal menu, you have throttling start at 90 (from 85)

Make sure you download Throttlestop (latest version) and Wprime95, try running the long test and make sure all your cores/threads are maxed at 38x throughout the test, the temperatures should not go above 90 in order for it not to throttle.

If it completes the test and the CPU never throttled, that means that it is rock solid.

The Vid to 0 really helps in keeping the tems low...

I can't tell for sure that you will have the same result as me but worth a shot.

 

Appreciate for the suggestion Xeneize. It'd would be greater if you could describe those settings (Vid, Max and Min Power) as well as when we need to change, and how we change them. Thanks in advance

Edit: I haven't done any tweaking yet. But I tend to start from the lowest level. Describing those setting would provide me some knowledge so I will know what I am doing. Because my CPU basically starts at 37 all cores (3.7 GHz for 2960XM. Correct me if i am wrong please), so I would go lil' bit further Will get it started tonite thanks

Advance edit: Sorry for the incorrect info. To be exact, the 2960XMs start with 27

 

you could always use...teamviewer...hahaha

side note:
first 18k gpu single 580m
Laptop Forums and Notebook Computer Discussion

 

Yeah but I didn't wanna throw you under the bus

I'm not an expert, I leaned from Johnkss and folks around here.

 

In fact, I just made a full 1024MB run of Wprime 95 with no cpu throttling at all with these same settings @40x..

John is this possible? 40x no Turbo boltage at all and only 800 pri plane?

 

I think I was able to do 42x with no voltage. Just had to provide it some current, around 800 sounds right

 

Exactly John and Xenieze... plus the info is posted all over these threads we just have to read. I posted a guide in my sig too but much of the same info is in this thread, the unlocked bios thread, the Da_g editing registers thread and the M18x benchmark thread... cheers.

 

46x with 100.5 bclk @ 15flex on wprime 1024m for 4.625ghz

 

Yeah I can do 46 with 9flex, just need 1060 pri plane.

47x however needs 15flex so my temps are insane without repasting not going to even bother running anything till then.

 

Man...I cant boot 46x no matter what I try

Always locks up during the wavy windows loading screen

 

yep, just ask the guy below..

it is looking like your chip is a 45x (what we use in the dt world of SB)

even my es could boot 47x...now i wish i would have did some serious runs with it before i sent the machine back. all i was running was vantage...(smacks one self across the face)

 

I think I just got "lucky" again

 

I can boot 50/50/50/50 on the multipliers.
*****
and I got a 1thread test of 5 runs to pass on intel burn at 5ghz @very high (4gb ram usage) setting.

 

okay can you post a pic with an 8thread 1024m wprime run showing the memory, system and cpu tab in cpuZ... just open 3 instances of it. John and I have 167seconds if your running 4.6ghz through the run you should be i at least the 170second or less range. someone could do a run at less flex than that its just a matter of cooling... you could use way too much flex and still get good scores if your keeping it just as cold.

 

my 167 was still using the da_g bios and not the unlocked bios. after using unlocked menu...i think i had it for 2 more days, before sending it back. with that unlocked menu bios...it opened up a few other aspects.

 

I can't finish anything... my temps creep up there in a hurry... give me a few days still waiting on my ICD7 to repaste.

This is the best I can achieve so far.... 46x doesn't stick at all... throttles to 44.28 most of the run and at about 85% foes way down to 25x for a few then back to 44.x again....

 

Take your time yes John I use the unlocked bios myself and edit only the registers I have to. Was the time you got over 5.1ghz and didn't get a validation in 1 active core at boot with or without hyperthreading... I've only tried all cores active and hyperthreading on... with no hyperthreading and only 1 core at boot is that how you got high clocks for cpu-z or was that with extra cooling?

 

I'm also with the unlocked Bios... In my freezer is where I can keep those temps under 90-95

 

The 0 VID helps keep temps down for sure its one of the safest ways to go but if your looking for an overclock for a bench that never drops from your targeted speed you will need more voltage than 0 flex on quad core or single core. Higher quadcore speeds take more voltage per 100mhz than raising single core speeds would. Try a 32M run on wprime where its a matter of few seconds you cpu has to run... on the 8thread test if you want high quad core 8thread speeds you will need a lot more than 0flex atleast at the ranges we are talking about I've had 4.8 and 4.9ghz runs on the 32m test they needed even more than the 15 flex to survive. I think some astounding runs can be done at 0 flex but if you want to survive a bench with extreme clocks you will need more flex

 

I never benched in a freezer I used a air conditioner to get 167 on wprime but its barely less than i got without which was 168 something once. Any other benches i've done were just with the fans at max on a basic notebook cooler in my house... no ac I had to use my parents for that. I need more time with the AC... someone's bound to just use dice soon and show everyone the most these chips can manage.

 

as a matter of fact just raise the flex if you get a bsod related to voltage otherwise leave it at the lowest possible setting.

 

Use more amps in the bios that's all you have to do and edit the throttle temp to your shutdown temp and hope you don't reach that.... if its too much for the chip but you didn't get a bsod for voltage than just lower the watts your using to hone in on what wont drive your temps out of range.. the higher you raise the amps the higher speeds you can maintain since it can maintain the watts you had set better.
******************
I have run 4.8ghz-4.9ghz 8thread wprime 32m so I know this works... i had to do it eventually since I had used all the amperage the stock 97amps provided
*****************
to raise the throttle temp over 90 you have to edit it manually and reflash your bios

 

Scook try it again start at 25 flex and try to boot but don't overclock the baseclock just to get a feel for what boots... when it boots start to lower the flex till your getting bsod about voltage on the bench your doing then raise it back up one. I got 4.638ghz on a 8thread 1024m wprime and it required 15 flex to run it without bsod by the end. so you should be able to boot at 25flex... Xeneize can do a 46x at 9flex. Its just a matter of temp and speed range your looking for... if temps dont raise up much the same speed can sometimes require less voltage.

 

I'm yet to get a BSOD actually... so I guess I'm getting lucky with the voltages

 

I can boot 25 flex. After working with John I know that my CPU likes 45x, 15 Flex, and 900 on Current. Adding more current actually drops the multi during runs

It loves those settings, rock solid lol

Change it to 46x and no amount/combination of amps/flex will make it boot

 

That's bad luck... I actually sucessfully booted 48x last night (1st try with 25 flex), but will not even try anything withouth IC Diamond repasting.

 

Read my comment in the other thread about paste.

Me and John are only using OCZ Freeze (unless he switched and I don't know).....the paste is not your limiting factor - I promise

 

50X guys I'm telling ya... mines OEM and John's is ES so no difference in handling. Current I have had at 300amps before and as you raise the amps you need to lower the watts set or you will go out of spec... when you raised you current scook you were telling the cpu it could operate even higher and thats probably why no boot... try setting 25flex at 46x but have the bios say 80 short and 80 long and once in windows and booted then raise the watts where you want them with throttle stop. If you set the current or watts too high to boot it will force it to run too high for the flex your setting. In my search to be ale to boot at 50x I figured that out and it works. If your not booting to windows its the flex needs to be higher.
******
I have gpus and cpu repasted with ICD 24
*************
I posted pic showing we can use 99flex in the unlocked bios and its in my guide too. If 25 isn't enough though it should go higher.
*************
the limiting factor if not the amps for Xeneize is the throttle on temp.. I set it to the temp I set the system to shut-off at so I don't see thermal throttling.

 

I agree, I think its just the settings... limiting things there, the temps he can take care of.

 

I'm experiencing a weird problem (1024M at 8 threads):
VID = 25: the CPU could only reach x41
VID = 15: the CPU could only reach x43
VID = 0: the CPU could reach x45

The temps were almost the same in all cases (+- 2C).

Stock pad, Long Duration PWR Limit: 99, Long Duration TimeWindow: 56, Short Duration PWR Limit: 99, Pri Plane: 900 (Tried to set it to 800 and the CPU couldn't reach x45), throttle temp: 90C.

 

so if you reach 45x with VID 0, you should be able to reach anything under 45x as well with VID 0... right?

 

I dont get your point by asking this but the answer is yes.

The thing I dont understand is that when the VID was 0 the CPU could reach x45 but when the VID increased, the max multiplier it could reach dropped (right at the start of CPU stressing, not temp issue).

 

My point was that I was confused as well... did you inject more current on 45x or were they all the same? (pri plane)

 

Everything else is the same (as stated in post #447), I only change the VID (and each time I had to change the Long PWR Limit back to 99 in the Power menu as it got reset to 0 in the Performance Options menu).
