'Laptops w. Intel Series 5 chipset can not take full advantage of fast SSDs'

yeah
my heart was beating so fast i pushed the emergency button and restart my computer lol
if i was wearing glasses i would have said it was my glasses but nop
i just reapplied your setting without changing anything to see if i can reproduce the problem

 

yes it happening again up to 165x

 

Try bumbing up the 'processor idle time check to 10,000ms or even default of 50,000 and see if it changes. Or try to drop max CPU % to below 100%.

Also do you have another app to view the multiplier, i deleted HW because it never got my GPU clocks showing correctly....

I tlooks like everything else is reading correcttly including temps....

 

i don't see my ssd speeds are lower than yours.. they are more or less the same..

 

is it only me
has anyone tried HWINFO?
maybe it's a software problem the way it compute the core ratio
what software do you use JJB?

 

i am using hwinfo latest beta and my multipliers seems fine.

 

Surprising results on a QM57 chipset with i7-840QM and Crucial C300 256GB.

First after applying stamatisx tweak: Temps between 54-59 C. All 4 core clock speed seems be around 1900Mhz. No much varying. CDM 4k scores are 25MB/sec read and 45MB/sec write.

Now disabled stamatisx tweak and applied JJB's tweak: Temps between 54-59 C. All 4 cores clock speed vary drastically 198 Mhz to 3100 Mhz. CDM 4k scores are 19MB/sec read and 33MB/sec write.

Please note my CDM 4k scores without any tweaks are 15MB/sec Read and 24MB/sec write.

 

ok i think i have found where the problem is
it's the throttle state
unclewebb give an excellent explanation of what the throttle does
when pushed to the limit the cpu start to slow down giving more and more errors
i replace throttle state to off and the problem is solved

 

That last post was 1000MB runs which, as I kept trying to explain earlier in the 50MB vs 1000MB debate, has vastly different results (lower on 4K) than the 50MB score. And that was before my final adjustments to the settings. Here are my current numbers at 50MB x 3 from my D: drive which is a bit fuller:



Also you mentioned earlier that your 4K reads are only 5MB/s slower, that is a 20% performance drop on the biggest bottleneck of the intel drive with the PM55 chipset. That's the one I would be most concerned with as it will show the biggest real world performance improvements.

I have several, for the most accurate data I use Everest, but ThrottleStop is also very good for real time multipliers even though it is a program for unlocking CPU throttling while on battery. Also CPU-Z works well but you have to use a drop down for each thread.

 

Thanks for trying separately NotebookGrail, it is very helpful because I try to collect as many data as possible

 

@stamatisx what is the downside of doing your tweak.?

 

i notice something from hwinfo it looks like my both core can go turbo boost now and reach 3.3ghz at the same time

 

I have that tweak applied for a while now (I didn't post it because I wanted to make sure first that it's ok) and I haven't found any, that's why I need you to test it further because I don't run the laptop on battery mode ever, so that's something we have to investigate as well.

 

That's why I mentioned before that I applied that tweak when I was overclocking my CPU, you need to check if you have increased CPU performance as well

 

My guess is that the flucuating speeds are from the 'proc. idle time check interval' or the or the 'proc idle time check' which adjusts how often the speeds can be changed. I think this is part of why this works, the quicker changes keep it from reaching a C1E state which was the problem.

Anybody know if these fast clock fluctuations can cause any long term issues with a CPU? It's not like their are any moving parts or anything...

 

Just to make sure guys:

I am not responsible if something happens to your hardware after you apply the tweaks.
Proceed with caution and on your own responsibility

 

Just want to say that I did what you recommend above and did not find any noticeable difference (the numbers I gave before stand).

Btw, Tip#2 is very important for almost any tweaks we are doing.

 

yes but the i7 620M is not supposed to allow overclock

 

Good catch, do you notice any difference is SSD performance with that at 5%. Also check your idle wattage, on battery I gain significantly with 0% min setting, tha's when i want to make sure the CPU fully idles....

 

Here's a list for the needed options:

FYI, None of the power plan tweaks need a reboot to work they change instantly. You can even do it while running CDM and see the change on the next speed run.

 

Makes sense.

Now that we know both the tweaks work, we are still in the unknown teritory of what will happen when the system is loaded or in the general long run. For now, i will act chicken and revert everything to non tweak state. At least, this makes me get a sleep as i was worrying if my SSD was bad.

 

Just switch to 'balanced' Power Plan and your back to your earlier settings (or whatever plan you didn't apply the tweak to)...

 

nop same wattage
I'm now at 20% and still get the same wattage results
the only difference i see is in the fluctuations of the core frequency
it doesn't go under 20-30% (1.199 Ghz)

 

I was almost ready to try this tweaks with fear of the unknown consequences before you posted this....

Maybe later then

 

I think that if you fill your drive to 67% you will see similar results to mine.

 

Yeah I know, just check with and without the tweak to see if there is any difference that's all

 

I think it does cause long term effect as transistors/capacitors have a MTBF they can last X switch on/off during their life time
speeding up frequencies reduce their MTBF
one soluce would be to keep the same switch frequency (ex: idle time check) but the amplitude is still a problem
same for idle disable tweak due to high temps (don't know which solution is the best anyway)
higher cpu temp means high wear over the cpu, the battery and the whole motherboard compare to high wear over few components which switch on/off
What I don't understand is how without any tweak the cpu can go into idle state without being shown into the core fluctuations in HWINFO32
we all know how idle disable can increase the ssd performance
it means that before any tweak idle state is enabled and used

you were right it does overclock the same way before and after the tweak

 

stamatisx,

Paying a little more attention to the device manager, this is what I notice with your tweaks above:

When I first apply these tweaks and reboot, I see the CPU's in device manager all have exclamation marks.

If I then proceed to uninstall those and rescan for new hardware, they are shown without exclamations. Sounds good so far, but now, the Intelppm tweak is set to 3 in the registry instead of 4. The processor tweak stays at 4.

If I don't uninstall the yellow exclamation marked cpu's and reboot they stay the same (yellow).

Do you have any comment on this behaviour? Is this expected/desired?

I really don't care if they stay yellow - the Inferno responds with some of the fastest 'ssssNAAAPPPP'! I have ever experienced!

Btw, not only do these tweaks improve the snap (and benchmarks) of SSD's, but they also do similar things for an XT bases system too.

 

I would find it hard to think this applies to our CPU's?

 

Good to know that you have improved performance.
About the registry tweak, you need to edit those two entries on the registry from 4 to 3 and then delete the yellow marked CPUs from the device manager. After you reboot everything will be back the way it was.
That's the reason I mentioned that restoring only the registry won't restore the default performance. (I do it this way and everything is as it supposed to be, let me know if yours behave differently)

 

Well, my GX660R and Vertex LE 240GB are afflicted with the power saving bug.

With no loud 4k R/W was about 13/26. When I loaded Prime95 while doing CDM I managed 18/52.

I'll be reading up on these tweaks.

 

don't know which part you're talking about so i can't answer your question

 

I don't know if all of the settings have already been reversed (just skimmed through the pages), but I found an interesting PowerPoint presentation from Microsoft detailing quite a few of the registry values with their meanings. Thought I'd share.

I'll be sure to toy with all these new settings, nice find JJB

 

This part seems implausible when applied to our CPU's.

 

ok you probably right
i was talking about the transistors/capacitors on the motherboard which switch to give the cpu more or less power when it requires more or less power to change from idle state to some other state

 

Okay! Lol...

I don't think those trans/caps need to switch at the speed the cpu does though.

 

i didn't say that
asynchronous transfert maybe but yeah i didn't make my cpu myself neither lol

slide 8 from friendly0fire link

 

Power cycling is harder on the CPU and motherboard components than frequency switching. However heat is hard on the electronics, and reduces the life cycle as well. This is all factored in how Intel calculates MTBF (in Hours of run time) for their processors. This is where the quality of all the parts used in a laptop comes into play, if they are over specified in relation to voltages, currents and temps (for each type of component) that will be a bigger factor in your overall life cycle.

Edit:in other words don't worry about it.

Now back to your regular scheduled posting of the SSD problem

 

Thank for your explaination othonda

so let's back to business
regarding the ssd problem
I would make some change to the JJB tweak as they make nearly no change over the results but avoid some problems (that it seems i'm the only one to have close to the core working limits)

allow throttle states: off
minimum processor state : 5% or more
processor idle time check : back to 50000 microseconds

 

Confirmed, for your situation you may want to try lower the 'proc. performance boost policy' below 100% and see if that helps. I also now have the 'proc. time check interval' at 10ms with no negative impact.

Good news I have match the 'on battery' setting to the AC settings for the CPU with a few minor changes, and then changed the rest of the PP settings to max power savings and it appear I am getting the same or possible better battery life while now getting full SSD speeds. A very noticable difference for me since the Envy 15 is throttled on battery to 9X, it now feels much 'snappier'

 

i still get a 163X ratio
it does really disappear when i switch allow throttle states to off
with this feature off everything else is just fine : tweaks approuved lol

my temps are just amazing 41C
wattage as well 5.1W
cores frequencies from 1.199Ghz to 3.283Ghz
and CDM 4k: 20.22/55.02

 

In this post here:

See:
http://forum.notebookreview.com/6658594-post193.html


I stated what a speed up disabling idle states did for me when running a 'Full' scan (on 2.5 Million items) with MSE. A few hundred posts later, we have the stamatisx and the JJB tweaks to play with.

How do they compare to disabling idle states?

Well here are the MSE Full scan times:

No tweaks / default settings: 2:45 or, 165 minutes.

Disable idle: 1:37 or, 97 minutes.

stamatisx & JJB tweaks: 1:14 or, 64 minutes.

I've asked before (with no responses), but does anybody else see these kind of improvements in the programs they're using?

 

I've only run a bunch of CPU benchmarks which all show equal or better performance than standard 'balanced plan' with no tweaks. Right now I am on battery and the difference is amazing on this computer which is throttled to 9x CPU on battery, it seems as snappy as when pluged in now and battery life with the same tweaks is doing great, may be a little better than before. SSD speeds unplugged are the same as on AC

 

ok i found out that the jjb tweaks is even better in performance than the idle disable tweaks for dual core program
i ran coresmark to test the cpu


dual core coresmark benchmark
jjb tweak
26th to 12th worldwide rank
217,51868s

idle disable tweak

no tweak
CDM 4k 3run 50MB read/write (MB/s): 16.41/29.76

standard laptop use (1 minute after the tweak is applied)
jjb tweak
average core power : 5.3W
temp : 41C

idle disable tweak

Your 'dual core' improvement is impressive. I guess I'll try coresmark becuase it appears that I am not getting the same increase as far as I can tell. Can you please confirm If you are using the "defualt" tweak settings that I posted or have yoy modified those settings? If modified, could you please share what you changed?

Thanks

 

I have changed the allow throttle states to off

I may have changed the minimum processor state to 100% as well as when I change back to default settings
the minimum processor state is set to 100% under high performance profile but i'm not sure
I should test back everything again but I'm kind of lazy

 

Can you guys tell me what kind of tweaks you guys are using? I can't find what you guys are changing

thanks

 

the tweaks are in processor power management under power options but you have to change the registry first

look at the jjb post page 31

 

Thanks, I have been trying to get the gains your seeing with no luck, and being a bit lazy myself, I did not note all the tweaks I have done.... I just reset everything back to default and am going to try again with my original settings you (just re-posted pg 31), I'll see what happens but now I forget a few of the settings that I determined were probably not neccessary from my original list. I would like to try and narrow down the minimum actual setting changes required to get the SSD boost and then modify my origianl 'step 1' to only adjust the registry 'attributes' that are needed for the tweak....

On a side note, and I'm not blaming you , I tried your 'paint' trick to copy all the new 'power saver' default settings before setting things for max battery life while maintaining the SSD boost. Like an idiot I rebooted before I saved all the 9 power saver 'defualt' images, Paint was minimized with all images open in the window.... Don't suppose you now a way to recover them if I had not saved it yet ??

Good news is that I was able to get full SSD speeds on battery and it appeard that there was little to no impact on battery life....
