ES* CPU Unlocked Multipliers Info Thread (Engineering Sample)

So recently I bought a few ES core 2 duos with the assumption that they had unlocked multipliers. They didn't. Not that I was super disappointed or anything, they're still decent.
I do think it would be good however to collect some info on these specific ES cpus. Not necessarily for overclocking or for any reason except that I have never seen it done.

Relevant information other than unlocked multipliers would be stepping codes, temp sensors, and really anything out of the ordinary.
I don't have a lot to contribute yet but I'll start off the list.

Core 2 Quads (Soviet Sunrise deserves the credit for these)

• QAVR - Q9200, E0, 2.4ghz, - unlocked multipliers - 1.05v LFM, 1.163v stock, 1.3v IDA
• QAVS - same as above
• QAJF - Q9200, unknown
• QDRS - Q9100, C0, 2.26ghz - unlocked multipliers, no temp sensors
• QGMU - Q9100, E0, 2.26ghz - locked multipliers
• QAVK - Q9100, E0, 2.26ghz - multipliers? - no temp sensors
  

​

Core 2 Duos

• Q174 - X9000, C0 - unlocked multipliers, good temp sensors
• QADW-S - T9300, C0 - locked multipliers
• QZNM - SP9400, 2.4ghz, locked multipliers - no IDA, no temp sensors

​

5/2/11
Imac specific (socket P) Core 2 Duos
All of these CPUs are like the T9*** (6mb L2 cache) series but with higher TDP and voltage.
These are not ES CPUs so they all have temp sensors, but occasionally there are other features left out.

• SLAQB - e8235, C0, 2.8ghz - 44w TDP - 1.1v LFM, 1.225v stock

​

If you have an ES or Apple Imac specific CPU or think you might, please run CPU-Z and report your findings. I will update this post.

 

X9000-Q174: working temp sensor and unlocked multi. The Q174 is a final revision es and is identical to the oem version under CPU-z except for the (es).

 

So the normal C0 steppings?
Thanks.

 

so QADW-S is pretty much exactly the same as production t9300. In case anyone was wondering about the ones on ebay.

They are pretty well priced. I cant quite get dual IDA though. Oh well.
Also the temps are really funny one core maxes out exactly 10c above the other. but not bad at all.
lol

 

er bump

I swear someone around here had an interesting B1 t9300 with unlocked multipliers...
im going to pick up some QJAZ soon tho so ill be updating this

 

Any word of luck with version QGMU of Q9100 ES QS?

What is a better choice between QAVR and QAVS and for what known reasons during regular everyday use when overclocked?

I found the QAVR here in US on my side of the counttry so it was a fast local buy. and I got a buyer for my old one so everybosyds happy.

 

QGMU is locked, some ES dealers say VR is better than VS.

 

Well I had the QGMU and I confirmed, it was locked. I moved to the QAVR and just getting to know it but so far, I like it. It was already a treat at stock with 2.4 but with Turbo on it uses 2.66 (10x multi), so all I did was up it a tad to 11x the now 11.5 for stability testing but just for the record, it did 12x at 3.1GHz but I didnt run any long test cause temps got to 70c so I want to use on a cooling pad or when I add my 2nd fan soon.

 

Don't the ES CPU's that were originally thought to not have working temperature sensors actually do have working temperature sensors, but you just need to tweak your software to read them?

 

Is there any difference from QGMU to SLB5G? I'm after a suitable Q9100.

 

Where did you hear that, and what software?
I'd love to be able to read the temps on my sp9400. Maybe I can read the ambient temp, that never occurred to me.

Not really.

 

I have an unlocked QDRS Q9100 (actually detected as core 2 extreme QX9100). Its got no temp sensors, but the multipliers are unlocked
Not having temp sensors is really not an issue. The GPU temp senstor makes up for it, and the laptop still modulates fan activity accordingly, so the laptop always stays cool.

I am looking to get rid of it so I can upgrade to a Q9200 for a faster base clock.

 

Same here, I couldn't see. multi was fixed, locked, temps read for what looked same. I only forgot to confirm hight vcore under load but I think it was like 1.17??. below 1/2v in idle power saver..


my QAVR loaded stock at 1.30v. Is this too high or normal for some of the ES? What are you guys with QAVR's getting for vcore at stock and what does it take to get 3.06GHz? What ab What is the lowest stable vcore I can do atx with turbo off? It does fine at 0.05v on 6x just fine. Temps feel comparable to my pulled QGMU so I guess that's the important part. What about 10.5x with turbo enabled? Does ThrottleStop account for turbo if a certain vcore is set?

 

thats a bit high. my q9100 QDRS is stock at 1.1625 and it runs at 2.23 ghz.

never heard about this. if anybody has any info on this please let me know. I'm fairly sure the temp sensors HAVE to be there, how else does the laptop know how to control the fanspeed?

 

I'm pretty sure your CPU temp sensor is not working.

The fan is probably controlled by another sensor (this sensor can be accessed through the EC). It gives a very rough value. You can see it if you download hwinfo32 and look at the sensors tab.

 

no cpu sensors picked up.

 

You might need to supply some info to Mumak to get support for your notebook, that's what I had to do to get mine to work with hwinfo32.

Here is the thread:
http://forum.notebookreview.com/win...uestions-reports-suggestions-discussions.html

 

what info do i need to give him?

 

I think this:

 

cool, just did all that we will see what comes of this.

 

Indeed, certain ES parts don't have the DTS sensors enabled or working properly. Depends on particular QDF and ES-phase (ES0, ES1, ES2, QS)...

 

So the ambient CPU temp would be under EC>CPU?
Thats very good to know. Seems to be be a bit hotter than my CPU up to 5c difference.
I didn't think my fan responded with my sp9400 which has no temp sensors.

Thanks for the qdrs info Technos, added to the main post. Do you know the stepping?

 

The EC temperature depends on particular notebook model and whether it is supported by HWiNFO32.
Check this conversation with technos and a new build to support his MSI GX720 readings: HWiNFO and HWiNFO32 Forum • View topic - No temp sensors?
The QDRS is C0 Stepping, ES1 stage.

 

Quads:
QAJF is as QDRS (ES1, C0-Step, NO thermal sensors), 2400 MHz, Extreme
QAVL, QAVK is E0, ES2, 2267 MHz, Extreme
QAVR, QAVS is E0, ES2, 2400 MHz
QJTA is E0, QS, Q9000
QGMT, QGMU is E0, QS, Q9100

 

I know about EC, I was using it. Thats why I said it was 5c hotter than my CPU.

I have "clevo EC" and then 2 temps under it, one is CPU and the other is temp2 (which now says max 731c but thats beside the point). One is my chipset temperature and the other is my CPU EC temp correct?

 

That depends on particular model. I added universal readings for Clevo EC, however the 731c doesn't look ok. I'd need to know the model and see the dumps using RW-Everything for ACPI DSDT and EC to check that further.

 

QDRS- 2.23 GHz, unlocked multipliers, C0 stepping, TMP1 enabled, TMP2 Disabled, identified as core 2 extreme.

 

...but essentially you can't read that temp on every laptop?
Thanks again for the info.

 

Nobody can. There's no universal standard for this and each vendor does this his own way, since EC is completely proprietary. Some have this temperature accessible via ACPI, but many others don't or there are many monitoring values hidden.

 

My 2 cent about q174 ES x9000.
Since im using one in my xps i want to point out that its not a rule to have perfectly working thermal sensor as i dont.
For instance, the second core thermal sensor is partially working. When the cpu usage goes to 0% it reports 149c while first core reports only 29c.
As long as the temperature raises, both thermal sensors align with difference about 2-3c.

Its just a problem with idle state as long as i tested. Multi is unlocked, but i cant take full advantage of it in my xps due to the huge power requirement it needs compared to the OEM.

As an example, to run stable/daily @ 3,8ghz as im doing now, i need v1.4750.
Another xps user with the same chip but the OEM version, it needs v1,3850.
With the same voltage i use he's able to keep the x9000 running @ 4ghz with no issue.

But the whole point is the price. My ES came really cheap (250euro) while the oem have almost double price (500 euro).
I guess im fine @ 3,8ghz as the temp never raises above 60c even under full load.

Step is C0, ill get a screen as soon i turn on the laptop.

 

I think the reason your voltage needs to be so much higher is because it's a C0 stepping. You should have gone for the E0 stepping.

 

I think the X9000 is only available in CO steppings. My Q174 X9000 did not have that temperature sensor problem. I was only able to get it up to 3.6ghz in my gateway 6860fx.

 

Ahh ok I keep getting confused with the x9100.

 

On the other hand my x9100 is e0 step.
I cant push it further than 3,6ghz on my m860tu because the cooling system sucks, otherwise the voltage is low (v1,3650 @ 3,6) and prolly it can higher than 4ghz.

 

It is rev EO (step QAVR). It loads as stock before I changed anything in Windows or ThrottleStop as 1.3000v.
Whar some of you guys with QAVR EO getting as stock vcore before overclocking? Is it safe to just lower it and if so to what should I start with for average 2.66~2.8GHz? Temps are ok and CPU fan on mine respomds to heat and kicks in when it seams to hit 48~53c loading.

 

They were talking about the x9100
but to try and answer your question, you mean undervolting? Well firstly the stock voltage is 1.163v. And then the IDA which is 2.66ghz is 1.3v.
If you are going to try lowering back to stock voltage while at 2.66ghz, I don't know if it will be stable. Make sure you have throttlestop in mobile mode if thats what software youre using.
Every chip is different, some will run stable at much lower voltages.

 

What do you guys think about adding the imac specific CPUs to this thread?

I'm going to add one that I have because its C0 AND it doesn't seem to have EIST, I will confirm this and the spec code later.
Also speaking of voltage I'll go ahead and add that to some models.

 

Is iDA and Turbo workingtogether on these ES? What is suposed to be regular vcore without turbo active? I dont remember if the AGMU had one or the other. So during performance encoding is it best to leave turbo off and just fix multi to 11.5 at 1.30? If I leave turbo on with set 10.5 @ 1.24v is IDA going to use 1.3 when needed? And is Turbo only using 11.5x on 1st core or will it run all 4 as such?

 

IDA is C2D, turbo is i5/i7 at least thats what I thought....

When you use throttle stop you are overclocking all 4 cores, its similar to what it can do with the i7 & turbo I think but 1.3v is still kind of a lot for normal use.
When you overlclock I think IDA is automatically turned off...

 

after reading all these posts,
i presume i can use ThrottleStop to unlock multiplier of a T9800 QJFL ES processor like an extreme CPU does?

 

Hard to say, but i think it' s impossible.

 

how did you manage to have multiplier 13.5 showing on CPU-Z, 13.0 on throttlestop and 12.5 when running orthos?

 

Well I know throttlestop updates much faster than CPU-Z and is more accurate.

 

ok so if i buy a T9800 ES which is said to be have unlocked multiplier,
can i achieve like the T9300 ES above increasing multiplier from 12.5->13.5 or higher?
if yes, are both cores running at 13.5 or just one core?
because it seems to drop back to 12.5 while running orthos, which is utilizing both cores that IDA will not work.

 

Nice thread. Ive been running a couple of iMac c2d's as per this thread...
http://forum.notebookreview.com/har...1425-apple-imac-specific-c2d-cpus-anyone.html

I have an E8335 2.93GHz (SLGEB) and E8435 3.06GHz (SLGEA). they are pretty good except there is no support for IDA at all. Otherwise they are identical to the proper c2d's. Both can run stable at their full speeds undervolted at 1.1150V, which is pretty good. The stock top VID of the E8435 is pretty damn high though, it really needs to be undervolted unless you want a hairdryer for a laptop. The E8335 by contrast has good stock VIDs and runs very cool and quiet by comparison, even though its only a half multi less.

I also have a couple of QAVR QX9200 quads. I've just recently been into overclocking them, but am limited by the laptops power circuitry (HP 8530w and 8730w). I can get 3.2GHz stable around 1.3250V, but I get this weird internal C0% throttling eventually on anything strenuous over 2.9GHz. The good news is that they can run rock solid and vid pin modded at 2.8GHz @1.2000V. In fact, on the 8530w I have to vid pin mod otherwise it won't boot properly. The default 1.3V IDA is just way too high for that laptop during boot.

I have also run one for well over a year on 1.150V @ 2.4GHz max using a vid pin mod, which also makes the lowest multi only 0.950V rock solid. It can also go to 2.66GHz now that we have throttlestop, still at 1.150V. The trouble with overclocking the quads is that you need to bump up the voltage a lot for each half multi extra.

I know its not quite relevant but I have an OEM E0 step Q9100 now too, and it can run in dual IDA at 2.53GHz @ 1.0625V linpack stable. Thats pretty darn good, its just such a shame the E0 step ES QGMU Q9100's don't have an unlocked multi or I'd be getting one.

 

QAVR is also cheap now, imo better than Q91. So don't be shame not getting a QGMU.

 

Why don't you take a look at your motherboard and see if its missing some power circuitry that you could solder on?

Oh and I don't think there are any ES core 2 duos which can have the multipliers unlocked other than the ones that already would if they weren't ES. I mean go ahead and order the t9800, thats what this thread is for but unfortunately it doesn't look like intel was into it this time.

 

The reason I wanted an unlocked qgmu is so that it can boot stable in my 8530w without pinmod. QAVR needs to be pin modded to 1.2v for boot on that machine.

Yes all my laptops I'm running quads in right now are the proper quadcorr mobo and chassis. It makes a big difference on the 8530, but it still struggles at 1.3V

 

According to laptopmonkey on eBay, the C2Q QAJF has no temperature sensor but maybe an unlocked multiplier.

 

I have a X9100 ES QHBQ Stepping E0 that maxes out at multiplier 16, but only for a short time.
For normal work(Office, Internet) it runs flawlessly at multiplier 15.
For 3dMark06 I have to use multiplier 14 at max as I get thermal throttle with multiplier 15.
