Where's the 9.5x multiplier ?

Well i was trying to OC my p9500 and i was doing tests with orthos.

I am using RMClock (undervolting) and with theses try, my system crashed or got a bluescreen and crashed. So I turned my power management off because I guessed that my voltage settings was maybee too low and made it unstable.

Well as for the OCing, i didn't manage to get results, but while doing some orthos burning, i saw in cpuid a multiplier of 9.5x while not undervolting (and 100% cpu and os usage) and with undervolting, 9.0x and 95% cpu usage

So im wondering why the max multiplier in RMclock is 9.0 instead of 9.5

So unlike said, there's a performance lost in Undervolting my cpu or im just wrong with my settings ?

 

RMClock does not support half-multipliers, so you lose 133MHz on each core when undervolting with RMClock. You can use CrystalCPUID to undervolt.

 

RMClock, from what I understand, does not support half multipliers. If a new version ever comes out (unlikely) it will likely support half multipliers.

 

And I guess this one support half multipliers ?

 

That guess would be correct.....

 

Does Crystal have mobile cpu support or do you have to continually check with cpuz as to actual voltages?
I was told it only uses desktop voltages, but I could be misinformed.
I might just give it a try and see if I can get my lower voltages under 1.00v, as I can't with RMClock even with the unlock voltage tweak. Plus it would be nive to run at a full 3.06 rather than 2.96

 

There will not be a new version on RMClock because author is dead. But you can change it to 9.5 ot whatever you want with regedit.

 

Whoa. Crazy necropost.

Like said, RMClock does not recognize non-integer multipliers. There are two other programs similar to RMClock that you can try out: CPUGenie and CrystalCPUID. Both support non-integer multipliers and are fairly solid undervolting utilities.

 

Sorry, Sov Sun, but you are wrong.

RMClock does recognize non-integer miltipliers. But it's not showing up them. How to make system to think about half? It's easy.

regedit => HKEY_CURRENT_USER\Software\RightMark\RMClock
We need key => PStatesData

It's 16 HEX. So here you can put the ammount of multipliers and make system think about rounding not to left, but also to the right side.

So each multiplier has FOUR 16HEX digits.
As example : 06 1B 00 31
1 pair - number of multplier (06).
2 & 3 pair are voltage - you can change them inside RMlock (1B 00).
4 pair is a TYPE of multiplier (31).

So we create so many of them whatever you want and play with each type.
About types:
20 = Normal\Standard\Rounding Left
31 = SLMF
22 = IDA

So if you need half-multiplier then just update last multiplier which is not IDA to +1.
So if you have 8 and 9 and 9.5 and IDA
you need 08... 09... 0A... (which looks like 10 multiplier but it's not)... 0B (IDA will be also +1, so from basic IDA 0A it will be 0B).

Have fun.


P.s. About CPUGenie and CrystalCPUID. I didn't liked them. Especially CPUGenine, it's working non correct and locking my cpu at 1.050V with Win 7 x64.

 

Most fascinating, h0w1er.

+1.

 

I really want RMClock to have half-multiplier support but I really don't understand how you did it. I'm sorry, I read your instructions over and over but it isn't really clear.

Would you mind clarifying everything again? Sorry

 

it took me a while to understand how but i got it to work

basically, if your top multiplier is 10.5x, you go in regedit and add a 11x multiplier entry (0B)

then when you open RMclock you'll see a 11x multiplier, you enable it, but since your processor is LOCKED to 10.5x, the 11x multiplier will run at 10.5x and the voltage you entered for 11x.

i will post some screenshots when i get back home if you need

 

Oh ok, got that. But how would you exactly add a 11x multiplier entry? I can't understand the steps posted above, lol.

 

when you open the specefied file in regedit, you'll see a list of entries, one line per pstate... the first pstate will probably end with 31 (SLMF) and the last pstate will end with 22 (IDA)

all the other pstates should all end with 20 (normal)

the first two digits for all pstates is the multiplier, so you want to add one entry right before the last pstate that will end with 20 and start with 11 (0B in hex)

example:

before
06 __ __ 31
06 __ __ 20
07 __ __ 20
08 __ __ 20
09 __ __ 20
0A __ __ 20
0B __ __ 22

after
06 __ __ 31
06 __ __ 20
07 __ __ 20
08 __ __ 20
09 __ __ 20
0A __ __ 20
0B __ __ 20 <---- added 11x pstate
0B __ __ 22

let me know if you still cant get it done and i'll post screenshots

edit: make sure RMclock is NOT running when you edit the registry file

 

Awesome mod! Having a few problems, but still, +rep for the idea how1er.

I made the modification for my X9100, and while I have an 8th state now, with a 14x multiplier (the max for my chip is 13.5), the voltage is screwed up. The only choice I have is .7125V. I know that the 2nd and 3rd values in each 4-set are voltage, and it should be set at 1.1875 from what I can see.

Any ideas?

And no, I'm not modifying the registry while RMClock is open, just showing the values.

 

Same prob here. My 10x multiplier (which I added in the registry) just shows me a 0.7125V VID, what is wrong?

 

Try to create first SLMF and last IDA.
Why you need so much of them? 1 SLMF, 1 lowest, 1 max, 1 max plus half, 1 IDA.
Also try to unlock all voltage levels in the registry.

 

Well, I'm just editing their default values. How do I know if my CPU supports IDA?

I don't need so much of them, I just need the default multipliers plus the max multiplier (9.5x).

Also, how do you unlock voltage levels? I thought unlocking voltage levels are risky and dangerous?

 

Breathing with air is "risky and dangerous" because of lethal death. Others "to do" in the list are just fun.

%Program Files\RMClock\RMClock_Tweaks.reg use the notepad as example:

"UnlockFid"=dword:00000000 change to "UnlockFid"=dword:00000001

"UnlockVid"=dword:00000000 change to "UnlockVid"=dword:00000001

"UnlockTM2"=dword:00000000 change to "UnlockTM2"=dword:00000001 (IF AMD CPU)

"UnlockEIST"=dword:00000000 change to "UnlockEIST"=dword:00000001 (IF AMD CPU)

P.s. IDA on everything that have 2 cores and more.

 

Man, can you just post some screenshots? I did what how1er one said but it really gives me one voltage only.

 

Yeah I tried it too. I successfully set the IDA and SLMF and tried all the tweaks. No dice, but no huge deal. Thanks for the help guys.

 

@How1er

Dude don't be offended but I really don't understand what your trying to explain. I followed all your procedures the way I understand it and nothing seems to work.

 

BUMP!

Can anyone help me on how to do this tweak?

 

sorry didnt check the boards in a while... i'm uploading screenshots right away

 

ok... after looking at my regedit and rmclock settings, here is what i did:

before
06 __ __ 31
06 __ __ 20
07 __ __ 20
08 __ __ 20
09 __ __ 20
0A __ __ 20
0B __ __ 22

after
06 __ __ 31
06 __ __ 20
07 __ __ 20
08 __ __ 20
09 __ __ 20
0B __ __ 20 <---- replaced the 10x pstate by 11x
0B __ __ 22

all i did was
1) exit rmclock
2) regedit the file specified by how1er
3) substitute "0A" by "0B" in the second-to-last pstate
4) close regedit
5) restart rmclock

the voltages should be unlocked by default since you did not create a new pstate. i think this is the best way, since it does not make much sense to have a 10x multiplier if you have a 10.5x multiplier

 

Ok, just tried your suggestion. It worked, showed me different voltages for the 10x multiplier which should be 9.5x for mine but when I set to 0.100V less than the default 1.075V, it just gives me BSOD, this is not right since 0.1V is just very little to start with.

I think RMClock seems to "try" to force the CPU to reach 10x even though it just have a 9.5x max multiplier, am I right? This explains the BSODs I'm having.

And I don't understand, why doesn't RMClock detect that my P9500 has a IDA pstate? I don't have a "22" in the regedit key.

 

I dont think you should worry about RMClock trying to overclock your CPU, it should be locked to the 9.5x multiplier. My P9700 undervolt runs very stable at 10.5x. Your BSOD is not necessarily due to the 9.5x multiplier, it could be due to one of the slower multipliers if you undervolted those too much. What you can do is only enable the fastest pstate in RMClock and testing it, then when you're confident you found a stable undervolt you can add the slower multipliers.

I have no idea why it wouldnt detect IDA. My suggestion would be to hit the "Defaults" button in RMClock and start from scratch.

 

{deleted}
Problem solved itself.

 

I can't see that file in regedit. Whats the problem please help me.

EDIT: Problem solved just needed to run my admin account

 

I've installed RMClock on Win7 x64 7600.
The problem that RMClock wrote nothing to regedit. Tried to install with admin, with compatibilties - nothing.

Can anyone to export whole HKEY_CURRENT_USER\Software\RightMark\RMClock please?

Many thanks in advance.

UPDATE ***
No need anymore. Restored this part from old system.

 

I have the same problem with P8700. Any thoughts?

 

I already said this, the undervolt of my P9500 is just up to 1.0375, so try yours and don't complain.

 

I read in another post that to enable the 9.5 (P8700) you only had to enable the IDA setting. I did that with the 9.5 voltage that was verified to be working with CPUgenie. However, it would still crash the computer. I came to the conclusion that when you enable the IDA or the fix mentioned in this thread, that the computer goes to 10x for a slit second (I can see that on CPU-Z) and if the voltage is not enough for the 10x, the computer will crash. So I just added a couple steps on the 9.5 voltage level and I am fine. CPUgenie is not working for me because sometimes it just doesn't apply the specified voltage levels (unacceptable for a sofware that you have to pay) and CrystalCPUID is a mess (wrong voltage levels detected/applied)

 

Hi guys!

Need some help with my 13.5x multiplier. This is how it looks in regedit:

08 0B 00 31 06 0B 01 20 . . .1. . .
07 10 02 20 08 14 01 20 . . . . . .
09 19 01 20 0A 1D 01 20 . . . . . .
0B 22 01 20 0C 26 01 20 . " . . & .
0D 2B 01 20 0E 33 00 22 . + . . 3 . "

How it,s needs too look for me?

Thank..

 

Just want to say thanks to how1er and roymathieu

I followed your tips along with the images provided by roymathieu, and now have a 9x multiplier

When testing with ORTHOS CPU-Z reports it as running at 8.5 and the correct clock speed

 

Benjamin,

in your case, look at the first 2 characters of the last line...
substitute 0D by 0E and you're all set:

08 0B 00 31 06 0B 01 20
07 10 02 20 08 14 01 20
09 19 01 20 0A 1D 01 20
0B 22 01 20 0C 26 01 20
0E 2B 01 20 0E 33 00 22

 

Hi guys I can't seem to enable IDA on my P9500... The box is greyed out and under CPU Info "IDA" is also grayed out...

It's a Sager NP8660.

I also don't have a IDA/22 line in the PStatesData key.

It looks like
0000 06 0F 00 31 06 0F 01 20 ...1...
0008 07 14 01 20 08 1A 01 20 ...1...
0010 0A 1F 01 20 ...

I changed the last multi to 0A to get my 9.5x but it was already 20.

 

I have a problem that i would be really glad if i got some help with...

I have unlocked the voltage and set all three multipliers (6.0, 7.0, 8.0) to 0.7125 (lowest i can choose), but when i look at the monitor and CPU-info i can see that the voltage moving up and down it actually never goes down to 0.7125!? I have also unchecked Os power management and checked 100 % min. because i have win 7.

Although this have lowered the temperature on max load, but i like to lower it in idle to.

If there is any help to you guys i have a Sony Vaio FW-series.

Thanx in advance

 

Hi guys! (... and ladies, if so)

The application works for me, but tweaks are necessary. I would imagine the "normal" public would appreciate out-of-the-box functions.

MY QUESTION:
ANY IDEA OF HOW TO OVERRIDE LIMITATIONS IN BIOS?
How can you extend the interval of VID (software / hrdware hack)? It is the question that comes back - see even the post just above.

I have extended the voltage range by tweaking RMC registry, but it's useless since it is limited by bios.

I am in the weird situation that I can stay perfectly stable on minimum voltage throughout all multipliers/FID. I suppose that voltage could be lowered more for all the FID's +/- the maximum.

If not, the excess of voltage is there - SHOULD I OVERCLOCK just for the fun of using that wasted energy?
Seems like I have a 10 centigrade headroom to do so, that's how cooler my laptop gets with RMC.
Would overclocking work together with RMC - or is there any soft to do VID + FSB control simultaneously?

If that is again a no-go - would it be wise to force the maximum multiplier within RMC or with something like throttlestop with the minimum voltage available?

THNX!

 

can someone plz help me, below you can see how it looks for me in regedit, how should i do to get half mulipliers?

0000 06 00 01 20 ... ...
0008 08 00 00 20 ...

I dont know why it isnt showing all multipliers? I have 6, 7 and 8 in RMClock.
