I7-3720QM(ES) with unlocked multiplier and 8MB L3. Worth getting

So did we find the reason? Flex (increasing voltage) settings? If it is so then I was right - not enough power

P.S. People who own AW always tell me that it is AW forum and I have nothing to do here LOL. I thought it is NBR.

 

Well it was the most convenient rebuttal to your 820QM argument without going into snobbish words like "hasty generalisation"..

On topic: if anything, keeping the flex at 0 helped me curb power consumption massively and hence temperature. Unless you run into stability problems, which you shouldn't with a limited multiplier, leaving flex at 0 is the reasonable thing to do.

 

i'll try flex later but i coubt that will work... you got my unlocked stuff than i do so maybe thats because its a 3820 but i don't know.

EDIT: wow i must have been tired or retarded when i wrote that here is rewrite.

I'll try flex later but i doubt that will work... you got more unlocked stuff than i do (in XTU) so maybe thats because its a 3820 but i don't know.

Also you haven't responded if you have been able to edit standard TDP. You got a 45w TDP chip so i still don't get how you can run about 45w TDP for ever without it busting you down to standard TDP. So either you have turned off long turbo timer limits or you increased base TDP. I would like screen shots of your TDP and you running above 45w TDP for 5 mins or more. Can you give us BIOS, TS, CPU-z, and XTU shots of your TDP and settings because i have no clue how you can run that above 45 TDP because it simple doesn't add up with how Intel made their chips.

Also this 3720QM ES chip does anyone know if its 100% unlocked TDP? as i have stated many times unlocked multipliers are useless if you don't have unlocked TDP.

 

I didn't edit the TDP at any point. Only changed the settings for short/long duration power max, neither of which was 45 to begin with. As the name TDP suggests, it's not up to us to change but the Intel engineer that wrote the specs for the CPU. Do you think that those guys running 4.5 on all cores on XM chips have TDP other than 55 W?

I've taken shots for XTU


CPU-Z


and TS


Really didn't want to go into BIOS as it sometimes screws up my XTU settings.. Hope you find the images helpful.

Edit: The CPU-Z shot was an afterthought, hence the different multiplier and Core VID..

 

your TDP is 45 w so i don't know how you can maintain anything above 3.5GHz because that requires 45w of TDP. You must have a mythical processor or something to maintain those speeds. I don't get it.


BTW XM chips can change TDP. my 920xm is at 80-85 TDP. Once i finish my cooling system i'll overvolt and push above 100 TDP. I currently only can go to 80ish TDP with my 920xm before it crashes due to lack of voltage.

 

My short/long duration max. powers are, as you can see, both set to 99. If I lowered them to 45 then I will of course be experiencing throttling. Another setting that can limit the performance is the core current max. The default of 112 A is already an overkill as I believe I can run my current clocks at about 80 A max. Apart from these, I don't think there's anything I can change to limit the clocks. (In the unlocked BIOS there are some "Advanced CPU power management" and "Advanced thermal management" options. Maybe you could look into those? Don't bother if you don't already have unlocked BIOS btw )

I most certainly do not have a mythical processor. It is a well-known fact that 3720/3820qm can OC by 4 multipliers and hold those clocks. Ask Heihachi88 for more confirmation on that

If anything, YOU have a rare CPU with its x47 multiplier

 

wont go that high as i told you. single thread apps will never break 4 core thread max. it'll only go to 38.25 or so. try running single thread you'll never get that 41x multiplier of yours. I have tried to get it to use single thread speeds on my 920XM and 3720xm but it'll never go more than 1x higher than 4x active multipliers. Whether i play Rome total war, which is single threaded or run prime95 or TS bench single or duel thread. You will never see the max single core speed. Try it you'll see. I have even tried to set affinity and no change you'll see everything on 1-2 threads and yet you'll only get 4 core multiplier speeds. I even ran more data and it still shows your only getting 4 core multiplier speeds. So to break this down if you got 47 45 43 38 multipliers you will only see 38-39 multipliers on any amount of threads and load. You can try 1,2, and 3 threads and you'll never see higher than 38-39. I don't get it.


Also your "99" TDP should only last 56s. As I have stated many times those short/long term TDP only last for as long as the "time window" which stock is 28s max is 56s. So your turbo boost TDP should drop to 45 TDP just like mine. I have stated this many times. Mine will go to 55TDP for the rated 28s or so and go back to base. Look at your settings. You should not be above 45 TDP for more than 28 or 56 seconds. Your window is set to 56s. I tried setting mine to 56s but its still stuck at ~28s window. As I have said i don't get how you get to run out of the short/long turbo time window....you have a mythical cpu because it is not designed to do that. Really wish you read my posts better. I have stated this everytime

Also my multipliers in XTU cahnged several times and kept going higher as i fittled with BIOS so i have no clue how XTU claims i have that high...it'll never go that high so it must be a glitch

 

You can never get above 4-core speeds? BOOM:

I have never claimed that my TDP has been set to 99. It's termed "Turbo Boost Power Max" and "Turbo Boost Short Power Max". As for the time window thingy, if you read the description, it says "The time window over which the average CPU core power must be below the Turbo Boost Power Max. (PL1 time)". According to this, the time window is not even concerned with TDP but only the long duration power max. The screenshot in my previous post was taken around half-way through a 10-min stress test. Only 56 secs?

I understand that it can be frustrating when you say things repeatedly and they seem to go unheeded. However, as my screenshots have hopefully shown you, what you believe and state to be true may not always be the absolute truth.

To end off on a constructive note, I recently learnt that there're websites that help you shop on the Chinese taobao.com (google "taobao English site"). I had a look myself yesterday and the prices were breathtaking. Would've got myself a 3940xm or sth if UK taxes weren't as high as they are.. If all else fails how about something properly unlocked?

 

as i said no more than 1x which your only getting 40 not 41 like you showed. BOOM

As i said your turbo boost TDP is 99, which lets you go higher than stock 55 turbo boost TDP. Again not listening. Also as i said it still has to do with TDP even if its overall TDP doesn't matter your still going longer than you should. Mine lasts ~28-35s from which is probably because of the average you stated. Your still getting performance that is not possible according to how the chip was made. Just as i am getting a magical 47x multiplier.....which has to be a glitch BOOM

Dude read Intel's statements....your chip is not running normally. I am telling you what intel has released stating that the window is only 26s stock and you set it to 56s average. You getting 5 mins of turbo good is not normal. BOOM


Now here is something else. I mis read something and so i deactivated it. It was called "Package Turbo Lock". I disabled it and it gave me control of all the other setting so I changed them to max and they still only give me that short turbo boost power time window

look here for a 4.0ghz single thread prime 95 screenshot


also to quote myself from another post :

***I ended up redoing my paste job and temps were improved by a few degree*** My point here was not about temps but about the fact that the 3720qm can get up to 4.0 on 1 core and keep 3.8 on 4 core.

So dont tell me a (normal) 3720qm cant get to 4.0ghz or cant hold 3.8ghz on 4 core ...
just need to up those power limit to get there, I use 85 for long duration power limit and 95 for short duration power limit. (Quite sure I cold get away with less then that too)

 

i am done wasting my time with you...you seriously don't listen worth anything

 

whatever you say, enjoy the throttling

 

So... did we ever decide if that I7-3720QM(ES) with unlocked multiplier and 8MB L3 was worth it? Because I just bought one and THEN found this thread (instead of doing it the other way around which would have been a lot smarter). :/

 

let us know if you can have fully adjustable TDP as well with no Turbo window

 

Surely you need to run XTU monitoring and look for throttling that way.

Prime 95 will fully load your CPU regardless if your skipping cycles.

Your oscillating temperatures seem to point to this xmadror.

 

Okay sounds good. I might have to ask for some direction in finding those things, this is my first foray into unlocked CPUs. I actually bought a 2920XM and this ES 3720QM at about the same time. The Ivy Bridge proc will go in a new Mini ITX build I'm doing.

 

Call this the comedy thread.
This chip is in no way shape or form an unlocked xm. Cpuz is playing mind tricks on you guys.

 

Unfortunality I have to say, that this CPU is the same Chip like a 3920xm ES. The Chip is labeled as QBC1. The only difference between these those chips is, that the Stock-Speed is for the 3720qm 2.7GHZ (27x100) and for the 3920xm 2.9GHZ (29x100). I got my CPU from upgrademonkey - this CPU is pretestet and does his work awesome. The only thing that I really need is a better heatsink.

 

Are you sure that it is the only one?

What can you say about turbo graphics frequency? is it 1.25 or bigger or what?
You can use gpu-z while stressing iGPU. Thanks.

 

Got a 3720QM unlocked ES. @4.1 at max power, same TDP ofc

MSI 1762

sorry if going off topic

 

How does it do at 47x on all 4 cores, BCLK at about 102MHz with flex at 54 and pri plane at 1325, and both TurboBoost power settings at 200W? If it can handle that well and run stable, it might convince me that it was a 3920XM prototype that Intel accidentally labeled as a 3720QM ES by mistake. Honestly, I would be surprised to see Intel make such a blunder. Not saying that it cannot do much greater things than a 3720QM or 3820QM, but I haven't seen any evidence (yet) to convince me that it is a low budget equivalent that will match the performance of a 3920XM or 3940XM CPU.

You don't need a better heat sink to test this.

CPU-Z Validator 3.1 - Freq : 4792.72 MHz (101.97 * 47)

 

Really. A 3940xm 3.0GHZ (30x100) and yours is a 3720qm 2.6GHZ (26x100). What does that have to do with anything?
Taken directly from his listings.

And here is the image for that same cpu

No where in there is an adlibed post of this (3720QM QBC1) cpu being an XM. (You know, Extreme Mobile)


But I do understand, you wanted to be cheap so you bought it. I know because the first go round I was cheap and I bought a "Real Unlocked" 2920XM ES first gen cpu. And you know what, it still beats this 3720 Unlocked cpu. It can do 45X on all 4 cores which you can not do sir. All you have is a "Real" unlocked 3720qm and that's about it. And it's only unlocked to 38X or 39X on all 4 cores.

Im only speaking because I dont want other users to fall to this line of thinking. Thinking that this chip is beating the system for what your paying for. It's not!

Fellow forum users, you have been formally warned.

 

The CPU-Z screenshot is just 4 illustration. And the "Engeeniering Sample"-CPUs are the same CPUs, except the multiplier. The multi is 29x 4 the xm and the 27(!)x for my CPU.

Here is a screenshot of my cpu (you have take a look on the multiplier, TDP and the L3-Cache):



And my multiplier is unlocked as same like a XM-CPU, i´d already said it´s an engineering sample. And there is just one 3720qm with this specifications: a QBC1. For detailed information use google and find it out . I´m sorry for beeing wisenheimer, but in this detailed situation you are not informed correctly. But no doubt you know very much about AW-notebooks!

And with a normal locked 3720 you were not able to set the multi over 45 (the highest multi of one core is 39 and on all 4 cores 37):

 

The part you seem to miss my friend is. Your chip is NOT and XM. It's an unlocked version of a 3720QM and that's it.

But it's real easy to prove this.
1: set all multipliers to 41X
2: run Throttlestop bench or wprime 155 @ 8 threads
3: watch Throttlestop window and take a snap shot of just how many cores are active
4: Post here.

But posting them screen shots...not really working for you my friend.



Edit:

And that is about the only thing you have completely right so far.

Edit: Again, I see allot of talking and no proof.


edit: now hit the apply button and run the test.

 

Unfortunality I´m not able to upper the multi above 39x on all cores, because I´ve some problems with the cpu-temps (single-pipe heatsink). But take a look on the 2nd screenshot: I´m able to set the multis over 41 in Intel XTU. But I promise you, I will do a wprime bench when I´ll get a triple-pipe heatsink.

 

You dont need a triple pipe heat sink my friend....
And you only need to run the test all of 15 seconds and take a picture while it's running. Then you can stop it.

I really am hoping im wrong and you have a fully unlocked chip able to run in the upper multi's, but it's really looking like it's not.
If you are worried about heat and are running an unlocked bios...You can disable HT. That will allow you to run only 4 cores. See if it will allow you to run that at higher multipliers.
But from all the testing we did on some of these chips..Best they did was 3.8 to 3.9 multi on all 4 cores with ht enabled.

 

johnkiss, you know that single pipe heatsink will make any unlocked CPU FAIL with those values and show throttle. And you want it. Lets wait when he buys better heatsink if he is planning to.

P.S. So what about iGPU?

 

Actually it wont.
I did this with a single heat pipe on a 2920xm es at 4.5 ghz when I first got mine.
It only needs to actually hold on 41 for 5 seconds to show it can go higher than 40X.

But we can wait if the masses feel this will allow it to run 41x for 5 seconds. Sure, no problem.

 

.​ As Fire Marshall Bill says... "Lemme show ya something"	OK, your CPU multiplier is definitely unlocked. That is very good. An unlocked multiplier is nice... I can use XTU to see my multipliers to 6.0GHz... But, that doesn't mean my CPU will run 6.0GHz. The more important question about your unlocked multiplier is, "What can the CPU do with it?"
	I did not hit the apply button, but neither did you

 

You can´t compare a sandy- and ivy bridge cpu. You´ll have to wait until I get my heatsink. Actually I´m a Desktop-Overclocker and these are my first steps in the area NB-Overclocking.

Once again i´ve to say sorry for my bad english and i have great respect to see that you take care to understand what I really mean :thumbsup:

With a 3720qm-cpu you can´t go above 39x. And the screenshot that I did is based on the statement that my cpu just only does 39x

 

Try a CPU-Z validation like I mentioned earlier. This should not create a temperature problem. See how high you can validate 4 cores. I think you can do that with a one-pipe heat sink.

Nobody is saying your CPU multipliers are not unlocked. They clearly are. The question is, how far being unlocked will take you. If the machine will not boot and/or run properly over 42x4 with hyperthreading enabled it's not all that beneficial.

 

"Scratching head"
Desktop over clocker?

Im a Desktop/Notebook World ranking over clocker.
LEAGUE RANKING
Worldwide: #205 out of 2574 in Xtreme OC league. (Highest rank of #78)
National: #28 of 2296 in United States Xtreme OC league(Highest rank of #18)
Team: #13 of 40 in PURE Xtreme OC league
Hardware Masters: #153 out of 20651
And team Pure is rank #1 in the world.

Let me make this more simple.
I can run single heat pipe on a 3940xm and still can do at least 4.1 ghz for at least 5 seconds. Is that more Ivy enough for you?

 

Maybe we misunderstood then. If you are saying your CPU can run stable at 3.9GHz on 4 cores with hyperthreading enabled, that sounds reasonable and having unlocked an multiplier is a nice benefit. That is definitely better than a stock 3720QM but not equivalent to an XM.

 

I know that you are in the right when you say that a qm cpu is not a xm cpu. The only thing that I want to say is, that a 3720qm QBC1 is the same like a 3920xm ES (important), because a 3920qm ES is labeled as a QBC1 too. My target is 4.2GHZ and I hope to get up the cpu to this level with a better heatsink.

But no question- and I know- I cannot compare my cpu with a OEM-xm CPU. I´ll never get this level in overclocking, but my performance is already better than a 3940xm which is not oced.

 

Hummmm, maybe it's just user error. And he doesn't know how to make the chip do what it's capable of doing...

 

I´ve reason to doubt it

 

Doubt what? You don't know what your doing or that you do?

 

It was an ironic comment I know what i do - trust in me

 

ahh.
Actually we want to help you get this going in the right direction, personally.
And would take about 1 to 15 minutes to know for sure if it would even work.

If your chip is like riri fifi then you should be able to do 44x to 45x on all 4 cores. You dont have to run anything, just show that it's possible.

 

For 44x - 45x I will need the H2O-cooling system from asetek I know that I made the mistake to use a noname thermal compound, but at the moment I am too lazy to install a better one.

 

I'm trying to explain this as simple as possible...
1: You do not need a super heat sink.
2: you don't need super duper thermal paste.
3: you don't need an air conditioner.
4: you don't need water cooling.
5: You don't need anything spectacular at all.

You only need to set it. That's it. Your not running any test. Your not gaming. Your not benching. Your not doing anything other than, checking to see if you can get it to load at that. And that's it. You are not putting any load on anything. The only thing you are doing is checking to see if it will boot at those clocks. Nothing more, nothing less.

 

Ok - here is a screenshot from shift 2 - cpu 4GHZ on all cores



Edit: A screenshot from Intel XTU with 42x (more is not needed)

 

Now there we go. That's better than an ordinary 3720QM is capable of, and it's a good start. Nice job.

But, more is needed to demonstrate what that ES is capable of doing. That's not as good as it needs to be to get very close to a 3920/3940XM. That's similar to what a 3820QM is capable of doing.

I would still like to see where you can get with the CPU-Z validation. That should not create any issues with overheating.

See below... this is with nothing special. Laptop is sitting on my lap. Fans are silent. System is idling at 4.8GHz and 51°C.

CPU-Z Validator
Freq: 4805.23 MHz (100.1*48)


Here's what you'll need for 4.8GHz on 4 cores...

 

I´d already posted that I never have the same overclocking abilities of a xm-oem cpu. a really great problem is, that i´m not able to hit the 99w tdp in bios. if it is a problem of the locked bios, the cpu specification or what else - i don´t know why. But I haven´t to encumber - it´s a cpu who costs 200US$ and it outperforms every non oced mobile-cpu. the performance hit in games with mgpu-configurations is impressive.

 

Brother Fox, just forget it. He doesn't understand. We'll have to wait for someone else who has this chip and is willing to listen instead of telling us what they can do. Which isn't helping anyone learn how to get the most out of spending 200 bucks or what ever it cost.

 

Tell me, why (and how) should I post a screenshot, when I´m not able to boot into windows with 44x?

Anyway: Here in germany it´s very late (2.45am) - I´ve to go to bed - good n8

 

Because we kind of wasted like 8 hours to get this far.

 

Well, have a good night and enjoy your Sunday. I hope you don't think we were picking on you... we were just trying to understand if that CPU would really work as well as we thought you were saying it would.

We did not really expect you to be able to run 44x with that CPU. If you could, that would be a dirt cheap CPU that performed better than any other QM option. It still looks like it might be a good low budget option for those that cannot afford an XM and want more than what an ordinary 3720QM or lesser CPU is able to deliver. It looks like it will run very similar to an overclocked 3820QM, which is still a powerful processor.

 

Hello and good morning, the first I´ve to say is especially from you I don´t feel picked up - so I´ve to say thanx for ur support. But there is more I´ve to do to get a performance near your AWs. At first i´d to flash a unlocked BIOS, because the actual regular BIOS holds me back to get better results (max. TDP-Setting 99W which seems too less for my CPU). To flash a unlocked BIOS I´d first have to downgrade (incl. blindflash) to A03. Then I have to flash a vBios with a higher Vcore for my GPUs - but I really ask me: Why should I do this - the performance is great in every game I´ve installed - so there is no need to do this. My Target is 4.2GHZ which should be a easy going with this CPU with a better heatsink. Multi 42x should be enough to solve the problem of the underutilization of my GPUs. And the last I´ve to say is that the performance is a bit higher than a 3820qm-Oem, because with a 3820 you can afaik max. 40x on one core and 38x on all.

 

I would do some more research on here before downgrading to A03. I don't remember the exact thread title but I know that one of our members did this and it caused him serious issues. I'm sure Mr. Fox or John can point you in the right direction.
