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

I wait of the official A10 and hope that I will be able to flash the unlocked A10 without downgrading.

 

To be honest....This whole thing was to see how high this es chip can go so others would understand what it could do. If I had this chip, I would have done this for the community already, but I don't have one so I haven't done it. We rely on other members to have it to help contribute to the masses. If no one ever took the time to exploit these things then no one would ever really know what they were capable of doing.

So that brings me back to the statement about me knowing allot about an AW. That would be because I try to explore every possible theory in to making it scream like the machine I think it should. Not how Dell thinks I should run it.

So that brings me to this picture...

1: You don't need 20 to run 42x You need 0
2: 28 needs to be at least 56 seconds, but really doesn't matter till you are much higher in over clock.
3: Your chip will not do more than 99 watt's even if you change that to 4024W
4: You dont need an unlocked bios to get to 45x either. It can be done off a factory bios.
5: New flashing method doesn't need to be blind flashed first. Thanks to Svl7's new method.
And the list goes on....

1 and 2 are crucial mistakes which generate unnecessary heat, throttling and lower than optimal performance. The Goal is optimal performance, not "hey look at me doing 5 ghz" That looks pretty silly to someone doing 5 times better at a far lower over clock. The key here is optimal performance. And what you get out of it is based on what you know. We have all the information to point you in the right direction, but if you make excuses at every turn on why you can't..really is not the Alienware way. We are all about what we can do. And why, with what ever means you have at your disposal. We understand that all you want to do is 4.2 ghz which is fine and all. Nothing wrong with that. We were only trying to see how high this chip can go....
And sorry if you feel Im riding you because i'm not, but if your a real over clocker then you would really understand why....

 

1. I know
2. Please describe the exact functionality of turbo window. I´d never heard something about it in Desktop-OC. What happens when I even raise it to 56ms (4 example)?
3. Thx 4 the advice
4. Hmm, I saw screenshots from the unlocked bios and there were many more abilities to tweak the cpu
5. I even read the thread at techspot. but thx 4 the advice

Your posting is a little bit different in comparison to yesterday and that is fine But what offers a cpu-z validation, when i get 100°C in Futuremark by 3.9ghz on all 4 cores? let me buy a better heatsink and then lets find it out, of what the cpu is capable.

 

When I started yesterday, I was mostly joking. Starting with my first post. You chose to reply like you had all the answers. so of course the posting took a different turn.

This all could have been hashed out with in the first 30 minutes, but rambled on for 8 hours.

1: We already know you wont be able to RUN anything at these high over clocks, not really sure why you persist in keep trying to do so.
2: This is nothing more than an initial test. To find out how high the multiplier can go. Nothing more. Not run furmark or futuremark. Not run a bench. Not run a game. Just sit there and idle, that's it.
You have an IB cpu so you can change everything within windows. You don't need more amps or watt's what you have to work with is plenty. we are not going for any records or stability right now. You would need to have a triple pipe heat sink and much colder temps to start pushing the issue. And we are not asking you to do that. Just a simple thing of set the multiplier and idle. that's about it. When it locks up. Power off and reboot. and try again, with adding a bit more voltage to cpu.

If you have teamviewer we can show you how to do it. Explaining seems to not really be working at the moment..not really sure why....

 

I believe 4ghz ish was the max for this sort of chip in the MSI which due to the earlier stepping I would rather have a 3.8ghz OEM with a bit of base clocking up to 4ghz.

 

I've gotten my 3740qm up to 3.991 with the level 3 preset settings in the bios. That's what 3dmark11 told me. Anyway. That's about as high as it goes right?

Hmm



sry 4 doublepost

4.3ghz on all cores

 

Ok, so now we are getting somewhere as to how high the multipliers will go.

Now, even with a single heat pipe. You should be able to run throttlestop prime test and set it for 4 threads(quad core with ht off)
Have Throttlestop open and set to turned off. You only need it to show watts and clocks across 4 cores.

This will tell you if you can even hit that on 4 cores.

 

See there, Brother Gerd. That wasn't difficult. Thanks for posting it.

 

Okay, I´ll do it tomorrow (I had to stand up in 3.5hrs 4 work at factory). But please give me some more instructions in terms of throttlestop, because i don´t have any experiences with that tool. Thx and good n8

 

Sure, no problem. We will get to it tomorrow.

 

Here's something you can digest while you are recovering from a hard day at work.... some of this (maybe most or all of it) can be useful for your CPU.

Alienware M18x R1 R2 Tripple 3 Pipe Intel Extreme Copper CPU Heat Sink 00MXJ5 | eBay

 

Hello

No probleme 3720QM ES

Spoiler

 

I ordered the HS - but 49US$ for delivery ....

 

so we're getting 4.5GHz on this ES model? Are any still available?

i am seeing a few for 250 right? How much does a 3720qm OEM go for?

 

unlocked multiplier - 8mib L3-cache and pretestet:

INTEL i7 3720QM QBC1 3.6GHz ES ,for 75 76 77 mobile chipset, upgrade monkey only | eBay

You can expect nearly the price what you´ll pay for minus the delivery costs

 

So far it's only 1 verified owner who can run complete test at 4.4 and 4.5 ghz with this 3720qm es moniker. We are now waiting on the second to emerge once he gets his 3 pipe heat sink installed.

 

You´ll get it. My 3-Pipe HS is already deliverd to germany but what are the next steps? Does anybody have experiences with usps and international delivery?



BTW. how much is the difference between the one-pipe and the three-pipe heatsink. And one more question: should i remove the t.i.m and use AS4?

 

This means you'll likely get it upcoming Monday/Tuesday (and have to pay taxes instantly when USPS delivers it at your door, before they hand you the package)

 

Did you actually check your system to see which cooler you have?

 

Stock is single pipe. That is what I got. I need to get my 3 pipe heatsink because the OEM 3720 hits 95 c with stock everything. I assume a lot of it is crap paste

 

Same here - installed is just only the single piper. But with stock frequencies i got max. 83°C. with 39x38x37x37 (which is similiar with a 39xx_xm) and stock vid afaik 89°C, with 39x on all cores 100°C and with 41x on all cores in games (no prime, F-mark etc.) max. 93°C. The actual vcore with 4.1ghz is 1.191V.

 

We have some triple pipe heatsinks spare IIRC, if anyone is struggling to find one you can email sales if you need one.

 

BTW not sure who said the statement that a 3720qm is not the same as a 3920xm...all intel quad cores are the same as far as i know just some have limited settings and restricted memory. They all have the exact same amount of transistors and die size so i thought they are the same chip but modified to limit the performance so they can make more money by having tiered CPUs. I remember we got into this conversation in another thread before.

 

I just wanted to clear a few things up. The information in the CPU-Z Specifications box is the exact information that Intel wrote to this chip when they manufactured it.

What CPU-Z displays in the top Processor Name box is its best wild guess at what CPU model this really is. When dealing with early ES processors, its best guess is not always right. Just because CPU-Z says in that box that this is some sort of 3720QM doesn't mean anything.

The retail CPUs have a CPUID of 0x306A9. This CPU has a CPUID of 0x306A4 which shows that this is a very early ES CPU. It might have some significant issues compared to a retail CPU or the issues might be very minor and never noticed during normal use.

The TDP data that CPU-Z displays is also written directly to the CPU. A 3720QM has a 45 Watt TDP. This ES CPU has a 55 Watt TDP so it is likely equivalent to a fully unlocked 3920XM. The XM chips are the ones with the 55 W TDP.

I recently discovered a magic register that shows whether a CPU has a fully unlocked multiplier or a partially unlocked multiplier like a 3720QM has. You can use my MSR Tool and type into the MSR Number box, 0x194 and then click on the Read MSR button and post a screen shot of that.

You will probably see something like this if the CPU has a fully unlocked multiplier.



If your CPU shows something a little different than an F in the middle of the EAX register then post a screen shot and I will tell you what it means.

MSR Tool
MSR.zip

Now head to EBay and start buying up some of those cheap 3720QM CPUs before the guy figures out what he's really got.

Edit: I just noticed.the 8 MB of L3 cache. That is another clue that this ES CPU is more related to the XM than it is to a 3720QM. The 3720QM only has 6 MB of L3.

 

I got it from upgrademonkey - pretestet and warranty included. BTW I already know what I "really got".

The differences between a 3720qm OEM and this CPU are:

TDP: 45W -- 55W
Stock Multi: 26x -- 27x
L3-Cache: 6MB -- 8MB
Locked Multiplier -- unlocked multiplier

 

full blown XM chips are for 600 bucks so i give it another 3-9 months and they will be 300-400 bucks i bet. So it is about that period where is it worth getting a pre XM type chip or get a real one in 6 or so months.... if you keep laptops as long as i do i would just wait for them to drop but this is one of those things if you got it 6 months ago when we started realizing what was going on it would have been worth every penny. Kinda wish i bought one 6 months ago but at this point i might as well just wait since i rather get an SSD now instead of an XM chip.

Speaking of that...i need to go over to TI and see if that guy ever finished his built in water cooling kit.

 

Hi unclewebb, have a look at my 9's and tell me what it means? Thanks in advance.

 

https://www.dropbox.com/s/zftjhvh0137rhe7/3720qm R4.png

this is mine and i have a 3720qm oem...very different. I know it is not unlocked but thought it would be helpful reference

EDIT: everyone is clicking read MSR right? BTW everything time i re open the program and do a read i get a different value....

Also what are the plus and minus for? I never touched them nor have i touch write MSR...figured best not to mess around ^^ I don't need more computer stuff blowing up in my face ^^

 

You have to type 0x194 in the MSR Number-Box

 

Gerd Weller: MSR 0x194 settles that. The F in that register confirms a CPU with a fully unlocked multiplier. The D in that register to the far right indicates the Flex VID voltage offset so it looks like you are giving your CPU a little more juice.

Your CPU definitely has absolutely nothing to do with a 3720QM.

 

https://www.dropbox.com/s/qbu8eauokklbso2/3720qm R4 2.png
here is the new one. Yea i got the 9 thing too

 

The 9 represents that you have +4 bins of Turbo Boost available beyond the default settings. This is what you should see when you read this register in a 3720QM, 3740QM, 3820QM or 3840QM. The 3600 series of CPUs do not allow any overclocking so you will probably see a zero for those CPUs.

 

Thx 4 the information and the effort

 

Stock is fine, but certain aftermarkets will do a tad bit better.

I was one of those people. A 3720qm oem is not the same as a 3920xm oem. As for how you want to define what is the same... Is something different.
As to this ES chip. We are trying to establish just where does it fall. And only testing can prove that.

Now that is good news! Now we just need to get a max cpu wattage read. Since the OEM's do about 100W max, but there is one program that will force it to do 115W max, but try doing that with anything else and it will just crash around 100W.

 

The Vid@13 is from my 41x afaik. But sometimes I forget to change the Vid back

4.1ghz is gamesstable with the stockcooler, but it´s too noisy. so I reduce the multi down to 40x and the vid down to 5.

 

Hopefully this will change when you get the new heatsink.

 

Gerd Weller - MSR 0x614 might contain some information about the maximum value for the turbo power limits. Can you post a screen shot of that MSR?

It's always interesting to see what $250 bucks can get you on EBay. Looks like money well spent so far.

 

Yapp and I hope i´m able to reduce the vcore as well.

 

i´d seen your post too late - sorry. I hope that is information enough

 

Well I just ordered one too Just need to source a pipe from the uk.

Thanks for the eBay link Gerd, I assume this is the same one you got?

 

IF that doesn't go through, Meaker is selling them.
Edit: Making this a bit more clearer.
Meaning he is selling the 3 pipe heat sink.

 

Yes, this is the CPU I´ve got from Ebay - but you´ve just to order a triple-hs too if you prefer to overclock the cpu



@unclewebb

do you get already any information about the turbo power limit?

 

That register only shows (1B8) which is the code for a 55W TDP processor.

0x1B8 = 440
440 / 8 = 55 W TDP

Some CPUs will also have specific limits detailed in there but your CPU shows zero so there are no turbo power or turbo time limits that have been specifically set. The bios might only let you go up to 99 but with the right software, I think you might be able to go beyond that. Better get that new cooler first before you go for that.

 

Now your about where we are in testing. What is the "Actual and Factual" watt's limits, which has to be performed from the machine itself. Watts can be set to 4000+. Amps can be set to 1023. And voltage can be set to 255 or 996.+ Vcore.
What it can actually do is the "more to the point" question...

 

Thx Lets gonna be crazy......(with that new cooler)

 

huh? i am talking about at the chip level. They appear to be literally the exact same chip except Intel changes what they hard code into the chip to limit it....as in if they didn't hard code limits like freq, multiplier, and TDP they would be the exact same chip. Quality is a different question. We were discussing if they might use chips that didn't come out as stable for lower level chips and they use the cream of the crop for the XM chips. Anyways that was what we were discussing in another thread. Also i thin Qing was in that discussion. Anyways, prove me wrong or right i would love to actually see some proof either way bit beyong that they are the same chip as far as i can tell. If they were different their actual size and transistor count would be different.

 

the last point you can´t forget. the best chips of the wafer are the unlocked xm cpus the rest are 38xx and more downleveled cpus. Actually i know fox and john are in right when they say a es cpu isn´t a xm cpu. you ask why?

- at first you don´t have any warranty to get the frequencies with stock vcore the cpu should be.
- es cpus are presample cpus that you can not get any warranty to run in stock settings with stock frequencies (thx 4 advance - upgrademonkey does)

in my opinion the es cpus with 8 mib l2- cache do the same performance as the xm cpus at the same frequency. but probably you´ll not be able to get these very high frequencies with this low voltage (i´ve gonna to try out)

But: When you have a mgpu config (especiallly AMD users) you should try this cpu - it maxed out your performance 4 less money that every biosmod can do!

 

Sorry about that HopelesslyFaithful. You are right. It is very possible that that is where these chips came from.
But coming from overclocking, I never just believe what is on paper. To many ways to prove paper wrong when it comes to performance and finding out what "we" think a chip is capable of doing. And the only real proof is to put it to the NBR testing method and find out the real.(Well, that list is a bit bigger than that with other outstanding members who contribute time and effort from other forums) So if it's a diamond in the ruff...then it's time for many others to take the plunge and get while the getting is good, but before we can put that stamp of approval down.... We need more folks to test it. I would sure hate to say, "Go get it" And come to find out, it was a select few that would do more than 4.1 ghz.


Side note:
That chip fits perfect with the AMD way. Performance at cheap prices!!

 

Cheers, I'll give him a shout
