How To Improve SSD performance on Intel Series 4, 5, 965 Chipsets (JJB Tweak)

Sandisk G25-G3 Extreme SSD 240 GB tweaked. Thanks!!

 

I am trying this tweak on my HP Pavilion DV7 3090ED with crucial M4 128GB SSD. The results so far seem to be a bit better.
Without tuning I scored 13,6 MB/s read and 17,2MB/s write for the 4k test in CDM. With tuning I score 21-25MB/s read and 39-42MB/s write.

I am noticing some weird behavior with Trubo boost/ cpu freq scaling and because of my issues I have some questions about some of the setings.

•Proc. performance increase threshold = 30%

When I read the description in my native language it seems to me that this value determines at what load percentage the cpu should start to scale up in frequency. So settings this lower would cause a rise in temperature but the system would also be scaling up in frequency a lot quicker. I think 30 percent (default) is fine because it leaves some room for the cpu to run idle.​

•proc. perf. decrease threshold = 85%

This translates to the load percentage which the cpu should start scaling down in frequency. I think it is weird that by default this frequency is below the perf increase threshold value and after the tweak it is way higher.
When my cpu has a 40% load it will scale up but when it it loaded lower than 85% it will scale down? Seems to me that 30% to scale up versus <85% to scale down could cause my jumpy cpu frequency.

In some older cpu's scaling actions should be limited because a scaling action could cause a minor delay in processing so when the scaling would be very active the system would suffer from minor delays. I don't think current gen cpu's stil have this "problem" but I am just wondering what actually causes the 85% decrease threshold to be more effective. Settings this value at 85% percent does seem to benefit the SSD's performance a bit but it does also cause my cpu's speed and idle/low load temperatures to be jumpy.

•Proc. idle demote threshold = 85%

The description from these settings confuses me. I think a higher idle state means more power savings. This settings determines when the cpu should go in a lower power state to deliver more performance.
I started thinking about this settings after reading this.
​

•Proc. idle promote threshold = 95% **

This settings will increase the powerstate and the energy savings of the cpu? Then why does it default tot 60% where the idle.demote setting defaults to 40%?​

•Minimum processor state = 0%

On my system high performance somehow set the min state at 100% when plugged in, this caused one core to run @ 2+ Ghz all the time.
​

The other values make absolute sense to me and modifying core parking settings really does benefit SSD performance. I think my confusion over the above settings is mainly because of the Dutch descriptions in my windows version. Hopefully someone can explain the actual impact of these settings, the standard description is a little short.

 

Just installed a new desktop system:

Asus Sabertooth z77 MB
Intel i7-3770K
Samsung 830 Series 256 GB as OS Drive
Hitachi 720 rpm 1TB HDD as D

Ran initial benchmark after just the basic tweaking of disabling Prefetch and all that. Set Power management to HIGH POWER and haven't tweaked the little settings as yet. Disabled Speedstep in the bios...maybe C1 next. Looks great...just a bit off on the QD32 scores...

Thoughts?

Thanks

 

Looks pretty decent to me !

 

Great guide good job

 

work for me! good job!

 

Hey guys !

I need a quick answer on this one, since ibood is selling an SSD ( OCZ Octane S2 SATA II 2.5" SSD OCT1-25SAT2-256G 256GB ) for €149,95.
Got an intel ssd 160 2nd gen, so how will it compare to that ?

Thanks !

 

So, I seem to have found some interesting results As you can see below.



I didn't go back to default settings after the first time I ran the bench mark, and with that gave me decent scores. After I did the tweaks I noticed I wasn't getting better scores anywhere, and in some cases significantly worse scores. So I set everything back to defaults and did a re-boot. This time my scores where horrid as you can see in the picture. My tweaked scores after reboot where significantly better in most cases.

Note all scores where taken with Winamp running on a separate HDD, and the music on the separate HDD.

** Due to some issues I had with my laptop (random freezing 3-6 times a day) A solution brought up was to, instead of editing the CPU idler, to disable it all together. I wasn't made aware , nor did I notice any severe heat issues, I'd say mostly due to the G73's cooling setup. But as you can see with the idle disabled all of my scores increase to a notable point. Especially the 50% increase to 4k writes.

To disable Idle go here "HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Power \ PowerSettings \ 54533251-82be-4824-96c1-47b60b740d00 \ 5d76a2ca-e8c0-402f-a133-2158492d58ad" and change the 1 to a 0 to get the option. It's then right in with the other CPU options in your power settings.

 

Legit double post I swear!!!!!

I'm sending this from my buddies g74 He just reformatted it today and got a new ssd in there. These are the results :



I didn't do the Idle tweeks; just the idle disable. 2 for 2 on Improvements going to run the test again to see if the 512k writes goes back up or gets higher.

 

Whats the option name in the cpu power management? I did this registry tweak and I dont see any new option :\ could you add a screen pic or something?
thanks.

 

Sorry I suppose I could have given you a bit more.
Here is the regedit page
Change the Attributes 1 to a 0 as you see in the SS below.




And this is the option

 

hi,new here but just like to say thanks for this power mod as my result have gone up by just over 50 percent on the 4k result.

ps.why are the results so different on this CrystalDiskMark 3

Would these tweaks work on a Dell Latitude E6430? It uses the Ivy Bridge Mobile Intel QM77 (part of the mobile Intel 7 Series family) Express Chipset.

 

Great thread! Thanks for this. :hi2:

 

Yes 9% improvement

 

Well after all the years I finally decided to get an SSD - not that I didn't want one in the past, just haven't been able to afford it. But anyway, I grabbed a refurbished Corsair F60 60GB drive from Fry's on Friday afternoon (SATA II, specs say 285MB/s reads and 275MB/s writes which I actually did get in testing with Ubuntu 12.04's Disk Utility, a nice flat line across 285 and 275 respectively). Been testing it out without actually using it for my OS drive just yet and I had been looking around for all the respective potential ways to maximize the performance when I happened upon this thread and the idea that there's a little glitch or bug or "feature" with respect to these chipsets of ours and see what I can do with it.

So, I have the following hardware:

Dell Latitude E6400 powered by a Core 2 Duo P8700, 4GB DDR2 667 MHz, 640GB Western Digital drive on the eSATA controller, with the Corsair F60 internally mounted (firmware was updated to v2.4 after I got it installed), Windows 7 Pro x64, utilizing the latest Intel RST 64 bit driver from 5-30-2012 v11.2.0.1006.

Took me awhile to find that driver because I kept seeing people with the iaStor driver in AS SSD and I kept seeing msahci (which isn't a bad driver at all, just not the best performing as we'll see). Anyway, once I got everything set up I used diskpart to clean the Corsair drive (it had already been securely wiped using PartedMagic so it was totally clean) and then a single primary partition with NTFS, labeled as "Test" and letter T.

I have Windows 7 plugged into the AC adapter and using the Balanced profile for this first batch untouched (meaning I haven't tinkered with any of the power profile settings for Balanced). These are the results:



About the same as the very first tests I ran when I got the drive on Friday, then started doing all the research that led up to the latest results found below. Obviously it's an older SATA II capable SSD, so that much I was aware of, but I wasn't expecting the 4K stats to be quite that low, so that's where the primary benefits always seem to come from with respect to these tweaks that JJB and Phil and the other folks have found for us.

So, did I get a boost in performance? Yes sir, I most certainly did.



A tiny boost on the general reads (about 6% by CrystalDiskMark), a nicer boost on the 512K reads (just shy of 10% by CrystalDiskMark), but low and behold look what happened to the 4K reads and writes...

About 140% improvement on the 4K reads (by CrystalDiskMark), and about 90% improvement on the 4K writes (by CrystalDiskMark)

Now, I can't say everyone will or has seen such a boost that I've noted (gotta re-read the thread again just to be sure), but I can honestly say that right now I am one very happy SSD-owning camper.

Why? Well, it's an older laptop so anything I can do to improve performance is a plus obviously. Not much I can do in terms of processor upgrades anymore (could get a faster Core 2 Duo but it won't make that big of a deal), can't do anything about the video chip (could upgrade to a Quadro-based mobo but not worth the money), want to get 8GB of RAM in here but the 4GB I have will do nicely, so that leaves getting an SSD and I got this Corsair Force F60 for $40 at Fry's, that's good enough for me considering what these tweaks have just provided in terms of performance.

Not bad for a refurb, eh?

 

Is there a more accurate explanation of those terms? (Let's say, with more words, i.e. "XXX is a % of cpu utilization at which the processor will enter into higher power state")

Processor performance increase threshold
Processor performance decrease threshold
Processor performance decrease policy
Processor idle demote threshold
Processor idle promote threshold
Processor performance core parking overutilization threshold

And, is changing any of them needed if one uses ThrottleStop?

Have you read the thread?

 

Well, I admit, not entirely (it's too big), only few pages at the start and at the back and I haven't found what I need to know.I don't want to blindly apply values, and I want to weigh in pros and cons, especially in regards to heating. The recommendations are more oriented towards pure SSD performance, and I want to be able to estimate what I will gain/lose, and of course experiment.

GL

 

37 pages is too big? Lol...

In summer 2009 I read the SSD thread in it's entirety before I started asking questions.

Keep reading... we can't learn for you.

 

Well, I found some explanations in ProcPowerMgmtWin7.docx. Searching by GUID everything pointed to that. But still I feel some things are missing, like what are the default values and what is the impact of various increase/decrease algorithms (ideal, single, rocket) in real time performance and were they tested at all, why there is Processor Performance Decrease Policy (40fbefc7-2e9d-4d25-a185-0cfd8574bac6) in this tweak, and no Processor Performance Increase Policy (465e1f50-b610-473a-ab58-00d1077dc418), the question about ThrottleStop etc.

*Edit: Also, what do the percentages of some of the settings apply to - whole processor, one core, one package (core + hyperthreading core)?

Also, I think Proc. idle demote/promote threshold are wrong, they should be as low as possible. The percentage is idleness, so there should be reverse logic. This way, the processor would operate (in a single C state) between 85% and 95% idle all the time, which is quite impossible. So it (maybe) just jumps quickly through the states from lowest to highest, effectively turning off all power features. Maybe that was the intention, but that could be accomplished in other ways.

In fact, everything needs to be explained better (I'm talking about Microsoft or processor makers). How is idleness (idle percentage) defined? Is it 100% - busy percentage? Then half of those settings are superflous (I'm talking about all the "hidden" power settings, not only in this tweak). Should busy %s (in these tweaks) be mirrored to idle %s?

Oh, so many questions... And so many edits...

*Edit 12: To explain further, I wanna test all those hidden power settings because I think the processor technology has improved since Win7 was made and maybe Microsoft put conservative settings, or 'one setting fits all' or 'it should work even on PIII'. I really think there is room for improvement.

So there's still no fix to this problem?

I just bought and installed a samsung 830 256GB into my dell XPS 1645. Unfortunately, I didn't see this topic/problem until I noticed my bench results were way off.

I applied the tweak, and saw some improvements but I'm still only getting 30mB/s 4k write. I might as well have bought a cheapass OCZ vertex with these speeds .
Anyway, none of the other tweaks are possible for me because both disabling idle and disabling CPU driver completely kills turbo boost for me. (1.6ghz max instead of ~2.7ghz).

With idle disabled I get around 50mB/s. Can't believe how much they failed with this design.. Had ages of throttling problems with both CPU and GPU, and now this.

 

This problem is 'fixed' - unfortunately the 'cure' is to 'buy a current platform'.

Your 3 year old 'first gen' Core architecture based platform simply cannot be expected to utilize modern components to their fullest potential. (It didn't even achieve that with then current SSD's; hence this thread, along with many others...).

Is it an issue for us owners of this older platform? Sure. But it is/was not a deliberate attempt at simply throttling our performance so much as it was to tame the power consumption use to better fit or exceed what was available for the mobile sector at that time.

Beside the 'tweaks' available in this thread, you can also try ThrottleStop 5.00a and/or do a clean install of Windows 8 x64 PRO with 8GB RAM (or more).

Both give substantial real world 'responsiveness' improvements to these older platforms - with Win8x64PRO even having the edge when responsiveness and maximum battery life are equally important.

ThrottleStop 5.00a is much preferred over these tweaks included here (imo); but it too also increases power usage (along with heat and noise, of course...).

What you may also want to consider is trying to 'unpark' the cores on your platform - I noticed a marked improvement with that also (with minimal detrimental effect on the battery) - especially with Win8x64PRO.

Do note that the 'improvements' I'm reporting have nothing to do with benchmarks (though I'm sure they'll improve too) - I'm talking about noticing results using the system in everyday tasks.

In the end, even with all of the tools, tips and workarounds available in this thread (including the one I've mentioned here) - this is still an old platform which pales in comparison to a current IB based platform with a minimum 8GB RAM on a current O/S (Win8x64PRO) and a current SSD.

For myself; my U30Jc is still 'very' viable today (although it is relegated to simple 'digital notebook' status now in my workflow) because of the many improvements Win8 and the core un-park utility have offered my i3 350m based platform (with 8GB RAM and a Sandisk Extreme SSD 240GB partitioned with ~75GB 'unallocated').

While upgrading the whole/complete platform is a 'once every few years' process for most of us, including me, I have always enjoyed close to 'always current' levels of responsiveness, usability and workflow efficiency by:

1) Maximizing the RAM my systems could hold (from 'day 1' of ownership, when possible).

2) Upgrading to the most current O/S (yes; even Vista was better than XP in workflow usability, reliability and of course; 'real' x64 support).

3) Upgrading my HDD's (now SSD's, of course) to the latest 'best of class' as they became available.


Even with all the above; I didn't expect the 'performance' of my systems to increase (new platforms are always needed for that to happen) - but what it did do is take away as many bottlenecks (including workflow bottlenecks) and alleviate as many issues (such as this one) as possible and allowing me to pick and choose exactly when that next big platform upgrade would give me the best bang for the buck once again (not only immediately, but also for the next few years when I'd do this all over again...).

Hope some of this late evening rambling helped?

 

Thanks for your reply.
I've in fact been using throttlestop since the day 1.. to prevent CPU throttling. It's already at turbo mode and 100% clocks.
I will try to unpark and see if it helps

edit: wow, 52mB/s 4k write! From 30! Why isn't this tweak in the OP?
I even noticed it when I rebooted, firefox came up noticeably faster..it usually comes 2-3seconds after all programs are loaded..

 

Glad it worked for you. Lol... actually, that was my impression of that tweak too.

 

Without reading through the entire 1400+ ThrottleStop thread, can someone point me to a particular post (posts) that relate to the SSD performance problem?

(Or, of course, repeat them here? )

 

No! Nobody says/repeats anything - I MEAN IT!

wpcoe HAS to read it him/herself!!! OR ELSE.


I have an Uzi and I'll take this thread's daughter hostage. I want an airplane with a hanger door and a helicopter inside. I want a limousine to pick me up from the roof and enough money to buy Bolivia. I don't want anyone following us and if they do: I'll have no choice but to blow up the limo (after I get to the airplane).

Okay? Okay? Everybody got it? Now, get me the limo/plane/helicopter/money and country and I'll go quietly.

Nobody better be following to my unknown location...

uh... I'm feeling so sleepy... what was in that (a dart?) through the windo...

a few hours later:
Hu! Wut, where am I?




I think I was DRUGGED!!! AND had temporary insanity. Also I have to pee. Please accept my apology.


Ah - Here, what the hey! I'll tell you myself.

See:
Maximum SSD performance on your laptop with ThrottleStop and registry mod



Hope that helps (and you enjoyed it too).

 

That was the weirdest read ever. Thanks..

 

Glad some of you enjoyed it. I was in a weird mood - but the official response is:

"I think someone hacked my system!"

 

Just redid it and tweaked a little, made my 4k random read go up by 20!

 

Oh, btw:
Setting Proc. idle promote threshold at 100% will kill all turbo boost on my 720QM.
Setting it to 99% will allow turbo boost

 

Thanks! Good to know regarding the 720QM on my W860CU +1 rep

 

Correction.. every time I reboot my turbo is gone. I need to adjust the idle promote threshold (by 1%, whatever) or simply switch profiles and it works.
Wth

 

I set mine to 95% seems to be perfect

UPDATE:

I am still amazed.....

 

Update: I ended up disabling all the tweaks from this thread because no matter what I did, after a while my CPU would be locked at 1700mhz (i7 720QM). You might not notice it, but take a look at your throttlestop. For me it would get stuck at 1719mhz or something.

Anyway, I noticed with throttlestop you can also disable sleepstates. Perhaps it's been mentioned in the thread but I didn't see it on the 1st page so here goes:
Set your throttlestop like so:
1)


2) Use core parking tool from:
Coder Bag: Disable CPU Core Parking Utility


I now have consistent 55mB/s 4k! No registry/power options

 

whoops.. double post

 

I have mentioned TS and the awesome Coder Bag utility here - but not in one post.

 

Sorry for bumping the thread but I wanted to say that this problem persists even on 7-Series Intel chipset.
I have HM76 and Plextor M5Pro 128GB SSD. Here are my results when usual and when benching 1 core in Throttlestop.


The difference is not so little. Anyway, I tried to use Throttlestop and Unpark CPU app without success. Same way as JJB Tweak. Maybe I will try Stamatisx Tweak and tell you how it goes.

 

I'd really love to give these steps a shot, but it seems the attachments are now gone. Anyone still have them?

 

Same, attachments are missing.
