PREMA BIOS MOD Review

I don't have the "Memory" tuning option listed, only:

All controls
Core
Cache
Graphics
Other

None seem to include any memory configuration options, so perhaps I'm limited to what I can set in the Prema BIOS? This is on a Clevo P651SE/XMG P505

 

I had that problem when I moved my old hard drive into the new P770ZM. What you do is:
1) Download fresh copies of your Intel Management Engine Interface, your Chipset driver, and XTU
2) Uninstall the Intel Management Engine Interface, the chipset drivers, and XTU from your computer
Note - this may involve going into control panel, device manager, and uninstalling driver by driver if you are not given the option to uninstall in mass.
3) Reboot.
4) Install Intel Management Engine Interface
5) Reboot
6) Install Chipset Drivers
7) Reboot
8) Install XTU
9) Reboot
10) you should now have all available options in XTU for your computer
Note - the options will depend on what the bios allows for modification, etc. If it is locked in the bios, it may or may not be available in XTU. Thanks for playing...

 

For me, it was primarily fully uninstalling the Intel MEI and fully reinstalling it that gave me access, but as those are the three programs that are at the core of it, I'd say that this, while overly inclusive, should work.

 

But I only just did a fresh install of Win 8.1 yesterday, installing all those programs in the recommended order (this was after I had flashed the Bios to Prema), the installing XTU, so I don't see how reinstalling them again would help, unless I' missing something?

 

I know that the chipset driver replaces one of the drivers from the MEI. Also, XTU installs drivers for MEI. So maybe just uninstall the MEI and reinstall it, uninstall XTU and reinstall it and try again.

Edit: Things can corrupt and also not install correctly, but it not necessarily cause a failed install. It is always best to verify the drivers first. On my other windows install, I only updated the drivers. This prevented me from having the ram in it. After uninstalling both xtu and MEI and reinstalling, it worked for me. Maybe I need to edit out the chipset part. But the point is give it a try. At worst you lose time. At best, you get the ram settings in XTU. I'd test this, but mine is RMA'd for an improperly seated heatsink (either a problem with screw #2 or the mount being too high for screw #2).

 

Not every model has XTU support for RAM...ZM Series has but entire W-series as well as P6, P15 etc do not...

BTW: In case you guys haven't noticed. The BIOS Mods also add some extra options in XTU and Throttlestop.

 

So there's no XTU support for RAM for the P651SE? If not, it's not a huge deal, as I can at least get my Corsair Vengeance RAM running at 2133Mhz in the Prema Bios and tweak the timings there too.

What does it add to XTU?

 

@Prema world ask mod of P150SM-A ultimate bios release Please, please, please!!!!!
One info, ultimate bios stock flash mei firmware to 9.1 damn

 

@Rhadamanthis

With 9.1 Firmware you will loose BCLK OC on SM model.

@ALL

http://forum.techinferno.com/showthread.php?p=125592

 

btw, would i be able to downgrade to pre 9.1 firmware on the ZM series to enable BCLK overclocking? cuz it seems like i cant oc it at all (crashing with +0.2 Mhz )

 

ZM series already has a 9.1 compatible ME "counterpart" in BIOS, so no need to downgrade there.
BCLK OCabillity is just very limited on most Haswell systems in general...

 

then i guess im just outta luck in that regard.... thx anyways

@Prema , I am still waiting for my RMA, but had a thought during further research on Dynamic Voltage Offset Undervolting:
Currently, a drawback to using dynamic voltage offset (DVO) is the offset must be true for all C-states voltages. So, if you would like to run balanced and have lower avg. temps by doing so, but want the DVO to be at it's lowest state when stable undervolting, you would need one of two things: (1) locked voltage C-States for all except the one for highest end processing, so that they are completely unaffected by DVO and the set DVO doesn't have to be stable at every given lower energy C-State since the offset doesn't apply to them, (2) individually customized C-state voltages that allow for the testing and setting of the lowest possible voltage for each C-state while at the same time having no effect on the other C-state's voltage. There is practically no penalty by running these C-states, but it can add cooling and lower power draw while not doing intensive activity, further prolonging the silicon.

EDIT: In addition, I have not seen a single motherboard manufacturer include this to date. I could be wrong, have not seen enough to make an educated statement on it. But in many other forums, this is the primary reason that it is recommended for desktops to not use voltage offsets.

 

@Prema yes i say. You write in your site and another forum but the problem is the new bios contain built in 9.1... This is why i request your magic mind and hand to release best bios mod for 150 sm-a.
Please prema, i donate, no problem

@Prema -
According to Raja@asus in the Asus forums (see https://rog.asus.com/forum/showthre...Mode-for-CPU-Core-Voltage&p=481284#post481284), Intel doesn't separate VID states for the C-states:
The control parameters for all of these situations are coded and developed by Intel not ASUS. The control you have right now is what they offer us. There are no separate voltage entries for individual C-States that I am aware of. The C-States only control the depth of power gating across the die - so there is no inherent reason for Intel to provide additional VID points for them.

Another thought I had as a potential solution:
Since the C-states work to control the depth of power gating across the die, is there a way to make these other C-states always refer to the stock VID at stock multipliers rather than the offset VID from the stock. They both have to be in there somewhere, right?

EDIT 2: Sorry for this, as I track down more information, I am trying to narrow down the issue and pass information. If I'm annoying anyone, please let me know. With that said, I have tracked the problem down further. It isn't with the C-states per se, but with the offset voltage shifting the entire VID stack. I am wondering if there is a way to set the offset without shifting the entire stack, but just the load VID value.

EDIT 3: FINAL UPDATE
So Asus (and others) have added an Adaptive voltage offset as well as a Core voltage offset. The Adaptive Voltage Offset applies to the Turbo voltage Offset. Adaptive Vcore makes it so that it does not affect any ratio outside turbo ratios. So there would be no issue with idle voltage levels. This is what I was getting at. Once my machine is back, I will check if Adaptive or Turbo voltage offset is available on the P770ZM. This would allow for the stable OC without the unstable UV on the lower C-states. Yeah (know the problem and now I know a solution exists in some form).

 

easiest thing to do would be to disable intel speedstep while keeping the turbo boost active, thus rendering the C-states and their associated VID change a non-problem

 

Of course, but I look at the end of the rabbit hole and product development. I am not saying I want it NOW, IMMEDIATELY, etc. I am saying we have this for awhile. Eventually, I'd like both speedstep for the coolest possible setting and a turbo offset. This way I find the lowest stable Vcore offset for the speedstep states to keep it cool when idling and surfing the web, and have two profiles for the turbo multipliers and further offsets so that I have work mode and game mode. It is a wish list. And I finally realized how to ask for what I want (joyous to have words!)! That is all!

EDIT:
View attachment 122446 The Additional Turbo Voltage is what we would need enabled to be able to do a full Adaptive offset without making the lower C-states unstable by changing the Vcore offset. Not to say we should not also try to optimize the Vcore and Cache offset (for obvious reasons), but this additional setting is what would allow for modifying the Turbo voltage without modifying the VID stack with the offset! Just trying to give a bit more info...

BTW: this is on a MS-168C-ID1 (MSI CR643) with a 2760qm thrown in it (only officially supports dual core processors). I can give the versions of Intel ME, MEI, XTU, and Chipset upon request, could dump the bios, etc. Anything in hopes of enabling that one little setting called additional turbo voltage!

Edit 2: Looking at something like this that Dufus posted for voltage management: http://forum.notebookreview.com/threads/guide-to-haswell-voltage-adjustments.742522/

 

Guys, what are best power saveing settings for P150SM-A powered by ATI R9 m290x and prema bios mod ? Is it possible to have more than 2:30 hour battery life ?

Bonus question:

Will Quadro K5100m work with P150SM-A and Prema Bios Mod ?

 

@ALL Prema Mod vBIOS for GTX980M/GTX970M updated to v1.1 and now on the blog!

Changelog:

- Thermal slider adjusted and throttle target upped to 92c (to make better use of Clevos FAN curve which only kicks to 100% between 86-90c).
- OC slider max raised to +810 as apparently some people hit a wall with their cards at 1560Mhz...LOL
- NVFLASH updated

ENJOY!

 

Hey Prema, is this MXM only or is the 4GB 980M also invited to the party?

 

@Cakefish P6xxSx BIOS Mods inlcude the vBIOS Mod, as their GPUs are soldered to the board anyway...

@ALL Updated stock BIOS for P75xZM, P77xZM, P370SMA, P375SMA, P377SMA, P6xxSE & P6xxSG are now on the blog.

 

Thank you very much Prema for your hard work, once again

Edit: I've just had a look at the website and notice that the P6xxSG BIOS is still at v1.0. Does this include the updated version of the VBIOS? Or will we 4GB 980M users have to wait until a future BIOS mod update to access the new VBIOS? Thanks in advance!

 

@Cakefish I'll update the P6 vBIOS along with the BIOS Mod.

@ALL Prema Mod vBIOS for 4GB MXM GTX965M released and now on the blog.

This is the card at stock voltage @ 1100Mhz (THX@Yun0 for testing):

http://www.3dmark.com/fs/4595992

And 1200Mhz @ just 1v:

http://www.3dmark.com/fs/4633741

ENJOY!

 

OK, I look forward to that day. Thanks!

Thanks for the updated mod for the P670SG!

Have a nice trip!

 

yes, thanks Prema for your good work!!

Can we G-Sync User hope for a Sager NP9773 / Clevo P770ZM-G ?

 

New ZM as well as their g-sync model Mods are already done but still in Prema Mod Partner exclusive phase...public Mods are always released with a bit of delay.

I am sure @HTWingNut has a thing or two to tease about.

 

Thats very good news
And in this Moment your Donation is on the way

Can you say something about a 980M G-Sync Bios?

 

What would you want to know about them?

 

I cannot get ftp://ftp.clevo.com.tw/P37xSM-A/OTHERS/Hotkey.zip to work it acts like there is no website or the website/fps is down?

 

@Meaker

I mean if there coming a Prema Vbios for the GTX 980M G-Sync

 

whats new? and the links for the latest HotKeyApp don't work.........what is full RAM SPD ?support?

 

Thanks Prema

 

Clevo FTP is just down sometimes...
BIOS and v(BIOS) for g-sync model will come...look towards HTWingNut for feedback.

New with these BIOS is a lot, bug fixes, cpu microcodes, performance tweaks, RAM SPD writes, latest BIOS & EC base, removed RAM locks in systems that throttle fast RAM, additional BIOS options, latest Intel vBIOS - LAN - SATA/RAID, updated style, latest ME Firmware, improved stability, proper support for latest GPUs and FAN control, unlocked vBIOS with removed throttle on W230SD (now also runs all cards @ 1202Mhz and not only for the select few)...etc...

 

@Prema Thanks so much for the update and all you do for this community, I really want to use your bios but I don't want to void my warranty I think it is stupid if I flash the bios and do it correctly and everything is okay that it voids my warranty :/ but w/e gotta follow xotic's rules even if I think I should beable to do what I want with my own laptop I paid damn good money for

 

Prima - pls help!

I have flashed to v2 of your bios for my laptop in sig. Now it will not boot. Tried F3. It keeps powering itself off after a random time and refuses to boot. I can't even get it to stay on long enough to re-flash to v1 or stock.

I think I may have encountered this before when I flashed to v1 but cannot recall how I solved it

Help appreciated

EDIT: YEP... basically f**ked

 

Does the current version for the p750zm support Broadwell processors, or is this functionality still in exclusive phase too?

 

If anyone could upload the latest hotkey update that would be great, europe ftp has the wrong version. Asian ftp always bugging ^^. thx.

great Bios prema thx .

Just one question : the Silent opition in EC : would it affect the cooling performance when playing or it's normally the same behavior under load than the cool option ? I read just above about the fan being always on in cool mode, but dunno about the behavior under stress.

Again as a prema donator : GOOD JOB it works flawlessly, you're good at what you do

 

there you go guys, hotkey 3.20.35
https://mega.co.nz/#!wxE32aAD!t6Pg84JOcZQ2kQdRyXYL4L7IUUa0VLsFSAk5eX0Bgxw
clevo's server sucked so badly that it took me like an hour to download this

 

The cool EC will spin higher at high temps. The silent one also spins up later at low temps.

User can get "warranty supported" customized Prema Mods with their systems directly from Partner Shops. There you get updates also before the public Mod is released (Check my blog).

Your system is probably running its RAM at its stability threshold. You can also verify this by only using a single RAM for testing stability.
(There are a few changes regarding RAM with the new BIOS in order to allow it to run at its designed speed).

It may have ran under-clocked with your old BIOS. In BIOS settings "Chipset" > "Memory" section change the "Command Rate" to "2N". If that isn't enough to stabilize the system either raise the 'first 3 RAM Timings' under "Advanced" > "Performance Tuning" > "RAMOverclocking" (e.g. 11-11-11 to 12-12-12) or lower the RAM speed manually (e.g. from 1866Mhz to 1600Mhz).

I have added Broadwell (non-Xeon) support for the BIOS released today...

@ALL Prema Mod for P75xZM and P77xZM has been updated to v2.

I am going back to hiking in the mountains now, you girls and guys ENJOY!

 

Thank you so much for all you do!!!

 

Coolness. But... uh... Mythlogic doesn't appear to have the updated files on their web site. Do you have any suggestions?

Thanks.

 

I always have seen Prema as a phoenix thing so when he says he's doing things like hiking my mental image is always crazy XD

 

To help restoring your image >>> I also do paragliding above the mountains

 

YESSSSSSSSSSS =D

 

Now i'm just really jealous XD

 

I have just dropped the Prema Mod for P75xZM-G & P77xZM-G on the blog.

ENJOY!

 

prema dropping them bios bombs

btw, any news on the maxwell undervolting front?
