PREMA BIOS MOD Review

Look on page 76 for Prema's post.

It seems it was my win8 portuguese iso fault since it hadn't the bootx64.efi file, instead it had bootia32.efi

With the new english ISO it now boots the pen drive in uefi mode, but gives the 0xc0000225 error that disappears if I unplug the HDD. I guess it's because it is formatted with MBR...going to backup and wipe all partitions.
Thanks for the help and for this great bios :thumbsup:

 

Hey there mate

So is the Wind8 UEFI really that good? Does it boot fast? And can Wind8 be installed on normal MBR without using the UEFI mod?

He said he would be making them for anyone to buy.

Keep Cool

 

It was a nightmare till I got it working, but I think it was worth it
The boot is quite faster with uefi (I also played with win 8 RC without uefi some months ago), and win8+uefi is way faster booting than win7 :thumbsup: With a SSD it probably should fly.

And yes, win8 can be installed in the old MBR way. At least the RC version worked like a charm here.

 

Heya Prema, any luck with the RAM control unit in the UEFI? I shall forward additional funds/supplies/overlords/pylons

 

Nope not by setting it in BIOS menu...sorry!

 

Hi there Prema, Im running the PM 2.1 for the w150ERx and every once in a while the fan blows at maximum for about 1 sec and then its normal again. might this be something in the new bios or whatever? its not a problem or whatever but was wondering why it does this cause when i check the cpu temp when it does that its like 50 degrees

Do more ppl have this "problem" ?

 

It maybe a combination of your systems temps and this EC version...will see if I can push a newer EC...

BTW:

To properly install windows 8 in UEFI mode you should first format ur usb stick to fat32 with diskpart. use this guide here:

1. Connect the USB flash drive.

2. Open an elevated command prompt in Windows 7 or Windows 8.

3. In the elevated command prompt, type the commands below one at a time and press Enter after each one. (see screenshot below step 5)

diskpart
list disk

4. Make note of the Disk # (ex: Disk 4) for the USB flash drive. (see screenshot below step 5)
WARNING: It is critical that you use the correct disk #. If you do not, then you could delete the wrong drive below and lose everything on it.

5. In the elevated command prompt, type the commands below one at a time and press Enter after each one. (see screenshot below)
NOTE: Substitute # in the first command with the actual disk # from step 4 above. For example: select disk 4
select disk #
clean
create partition primary
format fs=fat32 quick
active
assign
list volume
exit

then send all the files of ur win8 iso to the usb stick. Set ur bios to win8 OS and UEFI enabled.

Now boot from ur usb UEFI install stick and let it load the files.
When you get to the screen that lets you format ur drive etc press shift + F10 and you get to command prompt. type the following things there:
1. diskpart
2. List Disk
3. Select disk number (select the disk you want to install windows on)
4. clean
5. convert gpt
6. DONE

Install windows normally. after that go into bios again and enable secureboot. Go to custom and install the default keys. when thats done set the secure boot menu to standard again but leave it enabled and ur done. you are now running windows 8 in uefi and with secure boot enabled. thats how i do it not sure if there is an easier way or whatever. Hope it helps anyone hehe

P.S when you have bought a windows 8 laptop with the key embedded in ur bios you need exactly the same version as was pre-installed. i had this issue with an acer laptop wich came with windows 8 (not pro) and it was quite a search to find the right iso for it i have to say. most versions i downloaded gave me a message saying the productcode doent match any version you try to install or something like that. so for the non pro version i needed this iso: Windows 8 64bit NL DVD OEM HRM CCSA X64FRE NL-NL DV5 . this one was dutch but i assume this iso should be available in many more languages. Caause when i called microsoft and acer they both pointed to eachother where to get this disc hehe but the final answer was that those discs arent handed out to end users hehe weird saw on amazon they sell it for 100 euro..lol

 

I had the same issue, it was a real pain in the bum to find a win 8 normal iso. I would love to get a hold of one but they're rarer than dodos

 

yeah i had trouble finding one as well. really rude by microsoft and laptop manufacturers. When i called acer about it the first person said we dont support that we only support whats in the laptop atm, cause i wanted to put in an ssd and clean install windows unbelieavble. Then i called microsoft asking about that .iso and they said i had to ask acer lol....

I read now on some forum that some ppl had succes with re-installing by using this .iso file:

Windows 8 (x64) English
3416 MB
File Name: en_windows_8_x64_dvd_915440.iso
SHA1: 1CE53AD5F60419CF04A715CF3233F247E48BEEC4

Hope you can find that, if not let me know in this topic or send me a PM and i will try to find it for you. I cannot guarantee it will work cause i did not try this myself. Remember that if you want UEFI you have to create that usb as mentioned above or put the bios at legacy bios instead of UEFi otherwise it wont find a bootable device.

Good luck.

*EDIT* i uploaded that iso in 2 parts to wetransfer now so if anyone needs it send me a message and i will give you the links. or can i post those links here? since it is an original msdn file and it will be used with a valid windows 8 oem code.

 

I figured I would post this here so maybe Prema could chime in. I have been doing some research into ram chips and how they differ from other cards in our class such as the 675M GTX and I was thinking I am going to attempt to steal the ram from another GPU from a mobile card and solder it onto the 650M. Prema, is there anything in the BIOS that dictates what memory the GPU "expects" to see? I am wondering if, as long as I get the right type of ram and voltage for our generation card, it might work. I know very little about how it works but I have to try it to satisfy my craving lol

 

That' a no go , I looked in to this a while ago. I even contacted the Samsung ram sales reps. Apparently gddr5 needs very precise pcb traces with very specific turns to prevent back chatter as the memory operates at really high frequency. I. E. The decision to deploy gddr5 had to have been made when the motherboard was designed, alas ours was designed for gddr3 with much looser tolerances. You also gotta consider that our bga for the vram is totally incompatible with gddr5.
If you are still feeling brave, the Samsung rep told me they do produce a gddr3 chip that is higher binned then ours. It is specced to run at 2133mhz so i believe you can oc it to at least 2600mhz with fairly loose timings. Be warned, the chip is expensive and you gotta order at least 16 units, our mobo needs 8 so the extra chips allow more attempts should you mess up the soldering.

 

Is it pretty safe to flash latest Clevo/Sager stock BIOS using rufus?

W150ER
Prema Mod 2.1

 

Just flash EC first, then BIOS and don't use an older EC than v04 and BIOS than v07

 

Can't download latest bios. It says user's traffic exhausted

 

LOL, that's the second file hoster telling me that story...will add another one tonight.

 

I'm the 3rd file leecher to confirm this:

File owner's public traffic exhausted. (da3c7b74)


Does it mean I must get a paid account with Rapidshare?

 

as prema mentioned he will add a new one this evening, better wait for that then

 

DONE!

Added mirrors for the latest versions...will add additional links to older versions later.

Megaupload was shutdown by the FBI...
Mediafire asked us to pay or leave...so we left
Rapidshare didn't even inform me that some never before mentioned limit was reached...
It's Mega's a chance now...they will do all they can to please us...so as long as they are not taken down again...

 

Hi Prema !

Thanks for your amazing mod !

I've enjoyed great increase in perf thanks to my GPU overclocking with 2.1 UOV, but still have some CPU "issues" thougt.

I have an i7 2630QM @2.0Ghz (2.9 Turbo), but even with ThrottleStop, it does not go over 2.4Ghz. With OCCT, it even gets to 2.1Ghz.
I've put : 30 for time limit, 57 for power limit.

Here you'll find some charts I've uploaded :

Clevo w110er : la relève du m11x par Clevo [Topic Unique] - Page : 27 - Ultraportable - Ordinateurs portables - FORUM HardWare.fr

Could you help me ? I'm working on it for a week now, but still can't find out even if its normal behaviour or not...

 

I am not sure what it is suppose to run 4 cores at, the advertised 2.9Ghz is only a one core max.
What multis does the Throttlestop TRL window report for 1-4 cores active?

 

I have :
1 core = 29
2 cores = 28
3-4 cores = 26

Package power limit is set to 36W in TPL, and I can't change it. Is it normal ? My TDP is 45W though.

 

If the bios has set the lock bit, you won't be able to adjust the TPL using ThrottleStop or any software.

If the power limit is set too low, you will not get full turbo boost. The bios might be ignoring your power limit selection.

 

Hi,

I would like to load prema bios, but i'm quite new to topic and don't know with which i should flash into my lap.
Currently I have a everything stock i7 3630QM. I have run following tests ( I did set trotle step to Turbo):
1. Prima 95 (heating setup) is doing its thing at 28x multipler (~40W) and temps after 10min of operating are reaching 95C
2. When playing Crysis 2 after 30min CPU temperature are fixed at ~82x. GPU temperature is around ~75.
Multipler was reachng max 32 for a short while. Mostly on ~30 though.
3. In idle state CPU getting ~8,5W temp at 57C.

I have CPU/GPU repasted by xoticPC by this better termal compaund.


What BIOS version I should load to:
- avoide problems with overheating
- been able to overlock GPU
- been able to reach 33-34 multipler without overheating

I would much appreciate your help with that topic. I'm new with that and I do not want to distroy my new laptop

Thanks!

 

Thanks for answering

Shoundn't the PREMA Mod unlock these settings usually ?

I have limit#1 = 36W and limiit#2 = 56W in TPL. It seems weird, since my TDP is 45W. It looks like a setting for a 35W TDP processor, don't you think ?

 

What Notebook model do you have? If you have the W11 I would suggest you use the v2.1 UV EDITION to get the temps down...

I enabled it BIOS setup menu...
What is the "Long duration power limit" that you set in BIOS?

 

I have w110er.
As i understand, as i cannot OL CPU anyway (not in your relases) i should keep UV to reduce temps?

Any chance CPU will be having lower multiplier due to lower [W], and CPU having problems with lower voltage ?

 

Only the voltage of the GPU is lower the voltage of the CPU remains the same...you can reduce the multiplier of the CPU with Throttlestop down till 8x and also allow it to use Turbo while the dGPU is active:

To force Turbo Boost while the dGPU is active we need to:

1) Launch Throttlestop v5+
2) Set multiplier to “Turbo” (Highest value) and check the box.
3) Click “Turn On” in the bottom-right corner.
4) Click “Save” in the bottom-left corner.
5) Click “Options” and check the “CPU Mhz” box to see your current speed (optional).

 

I've put : 30 for time limit, 57 for power limit.

According to HWINFO, the following specs are :

CPU Power Limits (Max): Power = 72.00 W, Time = 64.00 sec
CPU Power Limit 1 (Long Duration): Power = 36.00 W, Time = 56.00 sec [Locked]
CPU Power Limit 2 (Short Duration): Power = 56.25 W, Time = 0.00 sec [Locked]


Should I follow the numbers indicated in the second line ?

 

So the Power Limit setting works as HWInfo just reports the value that you have set in BIOS.
The problem is that for some reason the BIOS auto sets your short therm TDP as 36, which should be higher for that CPU and since short is lower than long the whole thing won't boost properly.

I'll PM you another test BIOS to get things sorted...

 

Thanks Prema !

But, forgive me, I don't understand how you can see my settings are applied correctly...

For long duration I've set 30 as time limit and HWINFO gives me 56 and I've set 57 for power limit and it gives me 36.
If I switch the values, it seems it would work, but it's strange though...

Short term TDP isn't 56.25 ? 36 seems to be the long duration TDP.

By the way, why a long duration TDP of 36 if it's a boost ? The stock TDP is already at 45.

I'm a little confused

EDIT : Just to be clear, I've just set the long duration time and power limit in BIOS, as I don't have a line for short ones.

 

The BIOS sets the Short TDP to 36, which is too low...
The long you manually set to 57 shown as 56.25, which is correct.
HWInfo doesn't report the correct Long Turbo time, better use Throttlestop

Also because the Short TDP is lower than long it won't use the long at all as long has to be equal or lower than short....

Run the test BIOS, which will give you two new solutions...

 

I've noticed no change either in TDP or frequency, according to TS : around 30W, 2.4 Ghz with 4 threads on 4 (i've disabled hyperthreading for the tests, which by the way, increases TDP by 5W).

With 2 threads, frequency goes to 2.6 Ghz, and with one, to 2.8 Ghz.

So I have :

1 core = 28
2 cores = 26
3-4 cores = 24

We can notice it does not follow what I have in TRL :

1 core = 29
2 cores = 28
3-4 cores = 26

 

Ok. Does it cause any issues with UV, If I load OV is there any chance I have OL better ? Maybe UOV ? I don't know..
GPU tempes seems to be <80 while playing several hours in crysis ...

What is scarying me this 97C temperature of CPU while doing stress on PRIMA95 with constant TPD 40... (stuck on 28x multipleir)
I have never seen CPU going so high with temps :O
On the other hand I never saw it draing so much TPD even while gaming in crysis, but I did not seen it reaching more then 31x anyway via Turboboost. Is there any way to unlock advertised 33x and 34x to match 3,4 GzH for my processor?

I have been it using it max I have reached vitch "more information" ticket was 31 for a short while.. What about 32,33 and 34

 

Most people can still OC the GPU even with UV BIOS...
The 34 multi is only a one core Turbo. If you use TS and run the inbuilt bench you can set 1-8 threads. If you just select one or two threads your CPU will Turbo to 3.4Ghz because only one core will be used. I would not increase the TDP in BIOS in your case as CPU gaming temps of 80c are OK, but you shouldn't push it much further...everything is as to be expected in your case.

 

forgive me, I don't understand. Isn't TPD increase also increasing the temperature? Why would i need to do that?
by TPD increase you mean increasing "Short boost time" ?

 

Advertised Turbo speed is only the maximum speed for one CPU core.
For example the advertised Turbo speed for my 3612QM is 3.1Ghz.
But while using two cores the max speed is only 3Ghz, with 3-4 utilized cores the maximum Turbo speed is again reduced to only 2.8Ghz.
ONLY if a CPU DOES NOT reach its advertised speeds an increase in TDP values will fix that issue in allowing the CPU to draw more power and for a longer duration.
It is NOT required in your case as the CPU is already reaching its advertised speeds.

 

IIRC, short boost was a common thing with Sandybridge where it allowed the CPU to shoot past the advertised clockspeed if TDP allowed before settling in to the Long boost speed. Though, I haven't encountered this implementation with Ivy perhaps because Ivy tends to reach adequate clockspeeds with the Long boost thus no need for short boost.

 

Short package power limit allows to consume more than the advertised watts (not going beyond advertised speed) for a very short period of time to reach advertised maximum Turbo speeds. (In case of my example the 3612QM it is 43W)

The long package power limit is equal to the advertised maximum power consumption (35W in the example of my 3612QM) and again allows this limit to be crossed for a limited period of time. The multis are once more lowered if the limit is still crossed after that period.
(The power consumption raises along with the temperature of the CPU)

So in my example the CPU is allowed to cross 43W for a few seconds, then is allowed to cross 35W for another few seconds and after that it has to stay below 35W and multis are dropped accordingly if required.

From what I have seen IB processors have a higher tendency to sustain advertised clocks as the older SB.

(Sorry for all the edits/corrections, writing on a mobile is not my strength... )

 

So i did install Prema latest version UV So far so good.
Temperatures goes down 5-10'C on CPU and GPU.
The only thing I observ is with fn+1 option FAN is behaving like it is constantly trying to boost and then ti goes little slower and boost again from one step below, I do not get constant blow on highest speed. Is it normal ?

 

This is normal, I believe HT said it has something to do with the Temp Sensor polling rates. It reads the temps every couple seconds and notices the temps are lower, tries to force fan to lower speeds but then it's bumped back up to higher RPM because of the selection you made.

 

Thanks!


So i got another question. I do not see RAM timing/speed option in Fine Tunning.
At least not how it is shown W110ER/NP6110 | Prema Mod
I only have few options there.

 

That's because Clevo broke the RAM Tuning function on their latest BIOS.
For W11 Win7 users I would suggest Prema Mod v1.4 if they want RAM Tuning Options. Or even better wait for PMv1.5 which is going to combine RAM, GPU & CPU OC all in one BIOS for Win7.

 

can i downgrade it now ?

 

On W11 we can go from v2.1 to v1.4 (and the next v1.5) and back no problem, just load setup defaults and delete hdd and BIOS passwords before flashing between versions.

 

Any ME updates lately? It's been quite awhile since the last one. Just curious

 

I am using a new one since a few days...though not sure what's the best driver atm...

EDIT: Put it up for everyone on the blog.

 

thanx a lot
