Clevo Bios Mods

hmmm....true, theres still sufficient head room till Tjmax 100 °C. what would u suggest? something like 65W/75W? although theres not that much more gain to be had anymore, just about +100 Mhz in each turbo boost step ^^

 

Hmmm, I didn't know that until now. Can you direct me step-by-step on how to test my CPU if it does perform up to specs?

 

thats fairly easy actually: run Prime95 with the option "In-Place Large FFTs" and the appropriate number of threads to be used (i just checked 1 through 8 in sequence, one after another) for 3-4 minutes and keep an eye on the cpu temperature as well as the clock speed. if after 3-4 minutes it runs on the advertised clock speed at the respective number of threads used, then ure good to go. if not, the modded BIOS would be an option for you, provided your CPU temps arent that high yet on the stock BIOS.

example: with stock BIOS my CPU was clocked at 2.5 / 2.9 Ghz using all 8 threads after 4 minutes of Prime95. with the modified BIOS it runs at 2.5 / 3.2 Ghz (jumping back and forth between the two), which is pretty close to the advertised 3.3 Ghz it "should" run under optimal conditions.

PS: thx for the update prema, ill check the new BIOS once i have the time

 

though 100c is the official limit, we should not let it cross 90c on a daily basis...

Did you try the lates yet JB?

 

My P150HM came with a ES chip, and it is clearly under-performing. I would like to try out a modded BIOS. I have the 6990M so I cannot flash back to 1.06. I now have Bios 1.14 and EC 1.13. Any help is much appreciated!

 

true that Prema ^^ id actually already be uncomfortable with CPU temps in the 80s. havent tested the new BIOS yet, probably wont get around to it until next week. im having my master thesis defense tomorrow and im still busy preparing for that

cheers

 

So I got hold of the modded Bios 1.14 for P150HM. And I must say it's awesome. Passmark scored continuously around 6750 - 6801, and now it scores from 7071 - 7129 after 5 runs. It stays cool, after 3DMark 11 the CPU had reached max 68 Celsius according to HWMonitor. I will also check throttlestop. Thanks Prema!

 

Ya, steberg=big balls,
he tested the version 14 mod with additional ES CPU microcode from 06 bios.

That`s what you wanted jigglywigglyx

@Saltius just PM me if you want to send it to 伊然假面, too.

 

Prema, here are the throttlestop values;
power limit 1 & 2 = 60
turbo limit 1 = 32
turbo limit 2 = 0

 

EDIT: debweted

 

edit: debweted

 

So he flashed a modded 1.14 bios with the 1.06 EC?
That yielded him with 60/60 correct? That's pretty awesome. I am doing 48/60 atm, as you already know.

Steberg did you use all Clevo or sager?

 

nope, steberg flashed a modded 1.01.14 BIOS that included the ES CPU microcode from the 1.01.06 BIOS. no EC file involved here.

cheeres

 

very manly indeed
how did he find the differences?
went in blind with a hex editor?

Also prolly mentioned but I haven't checked is this a clevo or a sager bios? I am on Clevo atm, and well stuck now ;p

So to steberg
If it's Clevo can you send it over, would love to try it. If it's Sager, any chance you could do it on the Clevo BIOS?

 

I have a notebook clevo W150HRM based and i did updated the bios into 1.01.09 and Windows 7 stopped booting.
So i made a new fresh install and it continued happening the same thing, and running in "safe Mode" it also freezed at file CLASSPNP.SYS.

I have googled arounf this file and see that theres severall complaining about this problem, but with was after updating the BIOS, can anyone please help me?
Should i downgrade to an older BIOS? If so whish one?
Any other hints?

TIA

 

Oh ok. Are you using CPU-Z to monitor the clock speed?

AFAIK, the ratings are based by the number of cores and not by the number of threads, right? So what clock speeds will I expect for odd number of threads like 3, 5, and 7 threads for my 2670QM?

 

hmm

the modded bios has wifi disabled at boot

have to manually enable it

 

@jigglywigglyx, It's a Clevo BIOS, just send Prema a PM and he will send it to you. It has increased the performance on my ES Cpu, and I'm very pleased with the mod. And I have no problem with WiFi disable at boot. It works great! +1 rep for Prema!

 

oh this forum has +1? I forgot I owe prema lots

 

im actually using this pretty neat gadget here:

OrbLog Blog Archive Intel Core Series – Sidebar Gadget

concerning ur thread/core question: the answer is yes and no ^^ its true, the turbo boost specs are based on the number of cores but i found that an odd number of threads would get a slightly higher performance than comparable even threads with the same number of cores. thus, 3 threads would reach a slightly higher stable CPU clock than 4 threads, even though both are based on two cores with hyperthreading.

cheers

 

Are you using the unlocked W15HRM.09 bios that moral hazard made?

@jigglywigglyx YES, ALL BIOS ARE CLEVO BASED. PM send!

 

Which means? I mean how do you test this issue step-by-step? Sorry I'm not 100% sure on the process.

 

So steberg you sure yours worked? Mine just killed turbo so I got lots less performance.

 

Have you checked to see if your CPU's microcode is included in the BIOS?

If it's not, that can lead to turbo not working.

 

Ya, guess each ES is different, will make a special microcode combination for you tomorrow...

 

My ES is Q154 (ES2) Intel Core-2200, according to HWINfo64, on Microcode Update Revision it says Not Updated. CPU-Z id it as i7-2670QM - Genuine Intel(R) CPU 0 @ 2.20GHz (ES).
But it has for sure given my CPU a boost! I have run plenty of benchmarks that showed an increase in CPU-Speed.

 

Yes.

I'm also interested in finding if the boot splash can be changed to any BMP I want like my 6 year old Inspiron.

 

OK will take a lookat that bios today to see what that wifi stuff is all about...

YES we can change the splash, but that`s for things to come...

@Jiggly PM with fully ported microcode patches 06>14 sent. This should give you same speed as 06 on your ES, but will you will have latest bios.

 

Wow handsome!
Seems like i7 2720qm can't use this patch. Will you make one for i7 2720qm on P150HM?

 

The 2720 ES works best on 06 bios even though it limits the TDP to 45/56 compared to the 60/60 of 14 bios the benches are faster.
With the mod we can push the 06 a tiny bit to 48/60 and get alittle extra, but thats it.

There should be no problems to change the TDP with an OEM 2720.

 

These modded bioses, what models are these for?
I might be looking for a bios for the W860CU (or NP8690)
Does anyone know if it the original clevo bios can handle 16GB ram or if other bios is needed?
Cheers

 

@jaybee83

Have you read my question above?

 

btw, has anyone done a comprehensive analysis of the w150hrm bios versions?

hey! sorry i wasnt online for a while, since im travelling at the moment ^^

so anyways....ure asking how to specifically test all thread combinations right? or to be more exact: how to test the stable CPU frequency at one thread / two threads / three threads, etc? thats easy, just use Prime95, set it for torture testing in the max heat mode and specify what number of threads ud like to use.

For example: I start off with all 8 threads and let Prime95 run for 3-4 minutes, then i use the above-mentioned gadget in order to check at what clock frequency the CPU is stable. When that is done, i stop the Prime95 torture test and restart it, this time with 7 threads, another run with 3-4 minutes.....and so on. thats it!

cheers

PS: of course its most important to always monitor ur CPU temp while stress testing. the modified TDP values could potentially fry ur processor if not handled with adequate cooling!

 

No worries Thanks for the answer!

So for odd number of threads, what frequency should I expect from my 2670QM to consider it "working as rated"?

 

officially, id say at least the same frequencies as with the even number of threads, thus (in your case):

7-8 threads = 2.8 Ghz
5-6 threads = 2.9 Ghz
3-4 threads = 3.0 Ghz
1-2 threads = 3.1 Ghz

although it wouldnt surprise me if you see a clock of 2.9 Ghz appearing when using 7 threads. but in the end, only checking all possible thread numbers with Prime95 will bring you the hard facts
once you flash a BIOS with modded TDP i recommend always applying Fn+1 when stress testing or gaming, in combination with propping up the back of your laptop for improved air flow / lower temps.

cheers

 

Thanks. I thought 2.5GHz should be the frequency when all threads are running?

When you say prop up the back, I should just raise the laptop at angle?

 

as for the frequencies, the info supplied should be accurate. check the following page as reference: notebookcheck.com 2670qm specs

and yeah, i usually put some small object beneath the back of the laptop to prop it up it vastly improves load temps for cpu and gpu!

cheers

 

Thanks!

How high should I prop it up? is this applicable with the p151hm1 as well? How vast are the temp improvements?

 

Just an inch or so will make a huge difference. It depends on your ambient temps but 5-10C is not unusual (or more).

 

@Prema

alright, ive finally gotten around to testing the new modded BIOS u sent me with TDP values of 65W long / 75W short / 32s. My results so far:

ThrottleStop shows me 65W limit 1 with 32s duration and 72W limit 2 with 0s duration, so i guess 72W is the max for this CPU/BIOS combo?
Running Prime95 on all 8 threads right now, short peak wattage is at 66.4W whereas long wattage peaks at around 59.2W (how come it stops there and doesnt go higher for long durations?). Clock alternating between 2.5 Ghz and 3.2 Ghz, thus the same as before. Only that temps seem to be a bit higher than with 60W/70W/32s: after 20 min. with Prime95 im reaching 79 °C as opposed to 75-76°C before.
That being said, i think ill stick with the 60W/70W, since it seems to provide the same clocks but with a tad lower CPU temp ^^
thanks for ur help, keep up the good work!

cheers

 

Thanks for the confirmation. Is this a design flaw for the chassis of this laptop?

What is the safe temp limit for the GTX560M?

Also, I have a question regarding the Fn+1 fan pulsing issue. While stress testing my GPU and I enable Fn+1, the only fan that starts pulsing is the CPU fan. This is expected because the GPU fan is at full speed (so it will continue at full speed when enabling Fn+1) while the CPU fan is initially at idle and will start pulsing since it is not running full speed.

I then tried stress testing my CPU. While stress testing the CPU, I enable Fn+1 but the weird thing that happens is that both fans started to pulse. Is this normal behavior?

 

@kevin

id say critical temps for all GPUs would be 100°C+, but to keep it safe id make sure that it always stays below 90°C. same goes for the CPU, actually.
i wouldnt say its a design flaw. clevo laptops are generally known for their very potent cooling systems. problem here is that you would have to significantly increase the laptop´s overall thickness by applying bigger/thicker prop-up rubber feet to the base in order to improve air flow.
concerning the pulsing issue: ive noticed that the respective fans only pulse when the actual component is not stressed to 100%. for example: stressing the CPU to 100% would result in the respective fan to stop pulsing, whereas the GPU fan would continue pulsing. once i stop the CPU stress test, both fans pulse. on the other hand, when i run FurMark the GPU fan stops pulsing whereas the CPU fan doesnt change. i guess when u enable Fn+1 the EC keeps overriding the regular fan table, thus the fan alternates between its regular fan table specs and the Fn+1 manual override. once both specs overlap (meaning that the CPU and/or GPU is stressed and exhibits steeply rising temps, thus pushing the EC to ramp up the respective fan) the pulsing stops, since theres no difference in the manual override / EC fan table commands that the fans receive. my theory at least

cheers

 

Understood. Actually this is also my initial thought. The only thing I don't understand is why the CPU fan still pulses even though I stress test it already at 100%? My CPU temps maxes at 82C only though. Does it have a connection with those CPU core temps still not reaching the threshold for the fan pulse to stop?

 

hm, no i wouldnt think so, these temps should definitely be high enough for ur fan to stop pulsing. i dunno, i mean, as long as the Fn+1 feature works at all you should be fine. the pulsing shouldnt interfere with the actual cooling btw, are the 82C with a propped up laptop? and whats ur ambient temp?

cheers

 

Ambient temp is around 30~32C.

Well, propped or not the CPU temps are the same since the fan is not running at full speed (without Fn+1 enabled). This surely has to do something with temps since 80~82C core temp is still not enough for the fan to kick in to 100% RPM, right?

It's different with the GPU. Not-propped max temps are around 90~91C and fan kicks in to 100% RPM at those temps. Propped max temps are 81~82C (roughly 9~10C decrease in temps) and also kicks the fan to 100% RPM. Enabling Fn+1 at both instances will not affect the GPU fan since it is already running at 100% capability.

What do you think?

 

GPU temps sound deff fine to me try and see what ur CPU temps are like when enabling Fn+1 and propping up the laptop!

cheers

 

Enabling Fn+1 and propping up the laptop decreases CPU temps to around 71~72C. I was expecting 82C to be normal for my CPU since my ambient temps are high, right?

 

good stuff ^^ as u can see its really worth doing, actually! even though both temp values are fine, as long as u stay below 90C

cheers

 

Thats like the same problem I have with my ES, albeit my maxes are lower than yours.
