[Q] Achieving High Linpack Scores

Ok, so I've experimented a LOT with different ROMs, different kernels, different overclocking etc and I just CANNOT seem to break the 48.333 barrier. I've achieved this several times on CM6 nightly with Wildmonks 1190 kernel.
Tonight, I took a few different ROMs (Rods, CM6 & NAZTech Plain) and modified them removing anything that could drain resources such as Maps, Messenger, Voice Search, etc etc. I re-signed them, flashed them AND flashed Wildmonks experimental 1267 kernel (maxed JUST below because 1267 is an insta-freeze) and I STILL only achieved 48.333 max.
Any tips?
I mean, I'm happy with my phones everyday performance, I'm more or less just trying to clock a linpack score in the high 49's for S&G's.
(The linpack record for N1 is like 50, showing an overclock kernel of 1300 but I highly doubt that as I've never heard of an N1 achieving even 1267 without lockup)

my highest score was 47.6 I think, and for about 2 weeks I kept running linpack days and nights to attempt to get higher score
But after second week I gave up, I could get around 47.6 and no higher.

Anyone?

Nobody at all can tell me how to achieve better scores?

1.267 was achieved by 'the jesus phone'

Mine was 41.01 with Stock Nexus One (Froyo)
Now (with the new version of Linpack) I can't get more than 34.9xx

The Jesus phone isn't even in the top ten for Nexus anymore. Check my signature. I hit 50.525 3x using Wildmonk 1267 kernel experimental. OC 1228 mhz stable. The highest for the N1 is 55 legit. Persian.

what is the ideal setup to achieve maximum mlops on the nexus?
1. Rom?
2. Kernel?
3. ?????

Why are benchmark scores so important?!
I find that just using my phone on a daily basis, being able to complete all the tasks I need, and do it with style & grace, is enough for me.
My Nexus still outperforms every single device amongst me and my friends.
I can do way more things, etc. etc. you all know this.
So why bother with trying to get the highest Linpack or Quadrant scores?!
BTW: I read a post the other night in which Cyanogen himself stated that cheating on benchmark scores was easy. so ... hhmm.

Because we can?

@uoY_redruM
How come I can only score around 36 on my Nexus One? I did full data wipe, cache and dalvik wipe. Then installed CM6 RC3 and wildmonks kernel 2.6.35_SVS-950mV_CFS_AXI_720p_1113MHz_081910. I've also installed SetCPU and overclocked to max of 1113. How can get this above 40?

Jesus' phone was fast, but not as fast as mine!
Love,
GOD

Don't trust in the top devices list.
It's too easy to cheat
I can show you if you want it and put any MFlops you want.
So here is my advice : Use linpack to improve your device, but never compare your results to other, that make no sense.
I wish greenecomputing can solve this, maybe I should contact them.

Yeah, you might be right, however this popped up while driving right after flashing CM6+Wildmonk's 1113 kernel and shocked the heck outta me It's real, not faked....probably inaccurate, but real.

No worries, I didn't mean yours is fake
I just wanted to warn people about the reliability of the list and tell them to use Linpack as a personal device benchmark (ie after a ROM update) and not like a competition because some results may be totally fake.

well i was getting same scores with stock froyo, so just wondering why when overclocked with WM kernel and using CM6, shouldn't it be improved??

I personally usually get about 36 I would love to get 45

Overclocking?

Hello,
I've seached as much as i can and i guess as a rookie i am still having a hard time understanding all of the benifits of overclocking other than speed. I am basically Autonootered 1.01, would it do me any good? If so which Kernel should i go with or is this for the more advanced?

Do you know what overclocking is? If not read this: http://en.wikipedia.org/wiki/Overclocking
After reading that you still don't understand how OCing will benefit you, and the dangers of it, I don't know what else to say.

As of 24 hours ago I purchased a nook color rooted it, applied the 1.1 update zip, and overclocked the nook Using the 1.1 ghz kernel honestly I haven't notice any speed increases because I did everything straight out the box but quadrant scores are very high
Sent from my Vanilla Tazz using XDA App

There are no other benefits of overclocking other than speed. That's the purpose of overclocking. Stability and battery life is usually the trade off. With the kernels from http://forum.xda-developers.com/showthread.php?t=925451 I would say the risk of instability is very low. Especially since there are different levels of overclocking with those kernels. As for battery life, it doesn't feel like my battery is draining any quicker but I haven't compared my run time before and after overclocking.
I have had my NC since just after Xmas and I can tell you by my own experience that things were noticeably quicker when I went from an Autonootered 1.0.1 stock (800 MHz) to 1.1 GHz overclock. Before I overclocked I had been running stock for at 2-3 weeks. I mostly noticed the speed increase loading eBooks and websites (using Dolphin HD).
Personally, I would just go and try the 1.1 GHz kernel (kernel-1100mhz-omap3630.zip) within the link above. There a lot of people running on that kernel, including myself, that I don't hesitate recommending it. However, I would download all the kernels so you have them all handy just in case so you can flash to another kernel, such as stock, if for some bizarre reason you can't boot or have stability problems with the 1.1 GHz overclock.

As I stated I wasnt sure of any other benifits, other than speed with overclocking. But I do understand what it is. The majority of the threads i found that people were discussing it were either Froyo or more advanced than autonootered. Just trying to do my homework.
Thanks for the help guys.

Benchmarksssssssss!!!

Hi guys!
can you post your SGS configuration and tell us how do you score with Quadrant Benchmark?
mine is that:
SGS i9000m
kernel speedmod 13c - rom ZeroGingerMIUI with no OC Lagfix ---> 1800
kernel speedmod 13c - rom ZeroGingerMIUI with 1.2ghz OC Lagfix---> 2100
kernel super optimized - rom ZeroGingerMIUI with 1.2ghz OC Lagfix--->2350
kernel hacked Supercurio for GingerBread - rom Ultibread v1.4 Lagfix(no system) --->2000
yes, i'm a bench_maniac!

Stock I9000 XXJVK --> ~awesome scoreon my user experience benchmark.

Awesome... no words to describe!

Quadrant doesn't reflect real life performance at all. I used to get 2200+ with a lagfix on 2.1 but it was no where close to the real life performance of what I experience now on 2.3.3 JVK with no lagfix where Quadrant score is just 1020 .

Nice

quadrant doesn't reflect the actual user performance/experience because in the past i've had high quadrant scores but poor user experience.
but as the versions change (i.e eclair>froyo>gingerbread) i get lower scores but better user performance.

Agree my user experience benchmark is also off the scale .
Quadrant crap as always .
Why dont you post all these benchmark quadrant posts in the same place if you want to compare size.

Mine is scoring "awesome" too in user experience!

I personally think this thread should be removed I'm afraid.. For starters, there are a billion other quadrant threads, and nobody has F***king bothered, as mentioned to collate the values into a table. Also, nothing is worse than breeding a culture of people who believe that Quadrant accurately measures the mobile performance for all workloads.

I agree with Ausy that this kind of thread is not of much practical use. I run Quadrant weekly, but only to compare my phone to itself as a diagnostic. If the Q score changes radically, I try to find out why. I also use it to compare ROMs.
However, I don't see that the benchmark scores of two different phones will tell you anything of much value when you compare them.

Speedy Nook

Thanks to all the hard work from all the developers on XDA:
I love my nook with a Quadrant score of 2539!!!
CM7 v85, OC at 1.2GHz, cleaned /system/apps
Everything works: NetFlix, various markets, Flash, Youtube in HD, etc
I have a picture of the Quadrant scores, but I'm not allowed to post links yet

I would post this in the General forum for future reference.

Thanks, I'll move it to the General Forum

I feel the new OC Kernel is pretty great and I love deep sleep. But I will always remember the 4/24 Kernel at 1300mhz, which got me scores of 2700 regularly ;p
That said, I get about 2300-2500 (depending on the sd card) now, and I don't mind taking the small hit for the much better battery life.

With the 424 kernel, I was getting like 2500-2700 normally at 1.3gHz
Now with the 523 at 1.2gHz:
I had one really low one at 1400 something, I was shocked.
My highest was 2513.
Averaging around 2300-2400 excluding that first test.

I actually had the same scare (1400) lol. But that was the first test back with beta 3.1 and with just the 925mhz.

All tests were done with the exact same settings, so I was like what the hell is this.

I'm running Phiremod 6.2 with the 424 OC Kernel, and even though I'm too chicken to run at 1300, this thing just screams at 1200.

Not to derail, but how did you get Netflix working? Are you using the leaked APK, or just the website? When I try to stream from the website it gets an error.

Use the apk, test it and if it chipmunks, edit your build.prop.
A search will tell you all you need to know.

Overclocking the 8.9 Galaxy Tablet

Hey guys,
Posted under general questions and to my surprise not one reply in a week. So, I'm curious to know somethings about overclocking these tablets. What settings are you using? Have you had any issues with overheating and shutting down?What settings are recommended for web browsing, gaming etc? Let's talk linpack and benchmark testing. Where do you rank and how did you get there? Let's talk SetCPU benchmark scores, what kind of results can you squeeze out out of your device? How does someone pull off 41916.7 MFLOPS?! (Nexus) I'll start......
GT-7310 Running 3.2 / Motley Kernal / SetCPU
SetCPU Scores
Long Bench @ 178ms / Native @ 621.5ms
Linpack Scores
Single thread @ 42.4 MFLOPS / Multi thread @ 83.2 MFLOPS
Obtained running 1504MHz max / 216MHz min
Note: I have overheated and shutdown at 1504 web browsing. At 1400MHz I have had no issues. I see some scores are through the roof. I'm not to familiar with Overclocking and just would like to hear what you guys have to say. Thanks in advance. I may of posted this in the wrong area and I apologize. I would like this to be a thread on the topic rather than a Q & A.

Well I personally run my tab @1200Mhz with -25mV on the 1000&1200 steps, but anyhow, due to the interactive governor the most used setps are 216, 456 and 1200. I don't undervolt the lower test for stability reasons as I mostly work on the tablet so I don't want to test yet how low uV can go, don't have the time to test it right now. (Even though I'm pretty sure -25mV even on lower steps is still largely stable)
As for the set CPU test I tried them out on 1504Mhz: 150 and 595ms. I once pushed the tab to 1600Mhz but it ended up in an immediate freeze so I will skip on trying that again.
I don't have linpack but tried running GLBench 2.1 Egypt and the score was pretty embarrasing

Thanks for sharing. Since my post I have flashed aokp-34 galaxiansoup with v-3 of the Motley Kernal. Running 1400 on 216 no undervolting and am seeing a tiny increase in numbers. I'm still stumped on these linpack scores. This thing runs great. No complaints whatsoever. Anyone want to chime in on the best bench testing app or what the stock numbers on these 7310's are?

everyone will tell you that benchmark scores aren't very representative!
run the test 5 times and each time you will get a slightly different score.
i don't really care about benchmarking, as long as i feel that my tab runs smooth (which i think it does) im pretty happy. im normally at 1,4ghz and everything is smooth and stable!

Thanks for sharing. I couldn't agree more. My tab runs great at the same speed settings as yours. I just don't understand the numbers and how certain device's have like 100 times my mflops......I'm a numbers guy by nature, I like to see it on paper....but I am content with my device. Just always looking to make it cleaner and faster.....you know the addiction I'm sure.

Are you happy with this kernel? I found it stuttering and laggy...

Yes, I've not ran into any issues. Totally impressed and content with v3 motley. If there is a better kernel out there I'd love to hear about. I have yet to look, no need.

Been running a few custom profiles via Setcpu peaking @1.5GHz on B37 for a few weeks now. Other than a force close or two and an occasional browser freeze, which is normal with these roms, this thing is running pretty snappy. Gotta watch the temp though.

I sure hope that you've set up your profiles so that your tab overclocks to 1.5Ghz only occasionally, it's a thing that you HW can handle it, but will it on the long term?
Also, I regret that you can't overclock the bus frequency to get an overall performance boost (the GPU could really use it..) as on the Galaxy S

Yeah, I'm only pushing 1.5 on occasion, per profile. I normally run 1.4 all day everyday for the last 3 months with heavy use and no issues. Just gotta watch the temp. I've had mine to 113 degrees which kinda scared me.
