[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!

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

I think you are confusing FPS (Frames Per Second that Neocore gives you) with MFLOPS (Million Floating-Point Operations Per Second). Your Hero can get as high as maybe 5.4 MFLOPS, at least that is the fastest I have seen.
All of these are arbitrary measurements that probably mean very little. it is easy to get caught up in it. I run CM6 and consistently get 4.7 MFLOPS at the stock 691 overclocking. If you hero can tolerate faster processor speeds, it will go higher.

What is the fastest ROM?

I am getting annoyed with the speed of my Sprint Hero. the lag on the dialer is really annoying me, I hit dial and wait 5-10 seconds before the phone actually dials then it does the stupid vibrate after the call is ringing already.
Sometimes I think i did not hit the call button so i hit it again, and nothing happens for a while then suddenly I get 2 calls going at the same time to the same person.
I am rooted and running a 2.1ROM but I forgot which one, but it doesnt have any special features besides the super user app and htc sense.
Im willing to settle for something with out sense as long as it speeds up the phone.
I am even considering if its possible to unroot and to whatever 2.1 version sprint has out now and hope it fixes things.
Please let me know which ROM I should try, I dont care about sense, live wallpapers, special animations, just make the phone quicker.

cyanogen 2.2 mod is the best...overclock it to 768

Well, I assure you that using stock 2.1 will *not* fix your problems, especially lag issues. Better to stick to modded ROMs, to be honest.
After trying a few ROMs, I came to love ZenEXP. And with the 0.9.7 release that just came out, it seems like things have gotten even faster. You're rooted, so... do a nand backup, and give it a shot. Try Cyanogen too, as the last person said.

Please note that not every Hero will tolerate 768 on the processor. Really, seems only a select few can run it without stability issues. Mine will freeze instantly if set any higher than 710. This is why the new CM6 is clocked at 691, so everyone can boot it, and so it is rock solid. If you can get 768, then you are one of the lucky ones!

How do you get it to 768? I'm using setCPU and it peaks at 528

My max is 678.. but I put it at 652. Should I just max it out at 678?
Never mind its 691.. I maxed it.. I wont have a problem with battery overheating right?

The app that you use to manage your OC speed doesn't determine how fast your processor will actually run, it's all based on the kernel embedded (or flashed) onto your phone. If you're running stock 2.1 then SetCPU will only show your max speed as 528mhz because that's how fast the stock kernel is. Other ROMs like DarchDroid and CM6 have kernels that boost the max speed to over 700mhz. If you install one of those then you'll see massive speed improvements to your phone and with SetCPU you can either leave the kernel to allow for maximum speed or you can throttle it down if your phone becomes unstable and can't handle it.

Wow, thanks for the tip. I'm running the stock 2.1 atm because I haven't found a rom that combines both live wallpapers and multitouch yet. I play games on my phone often, probably too often, and I have to be able to use two fingers. The live wallpaper thing is just because I think it looks really cool, especially that mario one.

Cyanogen8

Cyanogen 8? Is this next? Or is this in the works? Also is 2.3.5 next and would it be numbered a different version when Ice Cream comes out? Also is anything coming from the devs to overclock to 800 yet?

It's been done. So very very few phones are even stable at 800, and those that could generally performed worse in benches at 800 than at lower clocks. Many of these devices bootloop above 700.

Cyanogen 8 will not come out yet since will most likely be ice cream sandwich. I am not even sure is 2.3.5 will even come out and no the devs can not overclock this device to 800mhz because is 768 is the limit of the processor. Most people's phones do not even run that smoothly at 768 anyways. If somehow the dev found a way to overclock it to 800 (impossible btw but this is just a what if kind of statement) since the processor can not handle 800 it would just overheat the thing and cause crashes.

Also, on a side note, this should not be in the Development section. This should be in general or Q&A

This belongs in Q&A for future reference.
CM8 will be next, obviously. It will be based on Ice Cream Sandwich, so no, it won't be in development until ICS is released to AOSP so that the CM team can start using that code. 2.3.5 is an update coming out soon for the Nexus S 4G that fixes wifi and network speed, as well as adding more secure NFC for Google Wallet. It won't really affect us when it is merged into CM7. ICS is expected to be Android 4.0, but it could be 3.5 if Google decides.
There is a kernel that goes over 800Mhz, but anything over 768Mhz can be unstable on some phones. I tried it and there were no real performance gains, but battery life was a lot worse. Performance was actually worse at the highest CPU clock, in my experience. Just stick with 768Mhz. It's stable and chances are that you can get even better performance at a lower clock. I get better battery and performance at 633Mhz. It all depends on each unique phone.

I can confirm that the Godmode kernel was able to push some phones, such as mine, past 800Mhz. Although I had a faster processor speed, my battery would drain incredibly fast as well as overheat. Even though I never hit a bootloop with the kernel, the battery life, overheating, and loss of performance kept me away. Sacrificing too much for having a faster processor speed. Normally I overclock to about 729Mhz and have great battery life, speed and performance in conjunction with a min of 19Mhz and a smartass governor.

Yup, I'm at 806 - 19 ondemand while posting this and I can already feel it slowing down a little. 729 - 19 on demand is my best setup. I've tested a lot with trying higher setups than that but so far 729 seems to be the best for battery life and performance on every rom I've ever tried

Correct me if I'm wrong, but from what I've noticed is that newer Hero's that were sold with Eclair as opposed to the original Donut, when I bought mine, are not able to reach those higher processor speeds past 691Mhz.

i bought mine at radio shack back in september and it was still on 1.5 and ive never been able to get over 768mhz without it freezing and bootlooping its different with every hero.
i stay at 352-691 ondemand and thats plenty fast for me

Mine was running 1.5 also and it will run fine at 768 but battery life suffers so I usually run at 352/710 and battery and performance are good (depends on rom kernel)

Hey rubyknight,
just wondering why 19? Ive seen people do that but can the processor really ever do anything at 19? if so, doesnt it affect stuff like wake. Im trying it now just to see for myself. Ive been playing with a really high min value between 480 and 576 with the high at 748 and it actually doesnt only seems to affect battery life a little, both on the .29 and .35 kernels on jaybobs roms and on OMFGB.

so update, ive run it at 19/768 on demand all day and after 11hrs 13 min its at 60% thats not bad for my phone! and there was almost no performance difference. Just the slightest UI lag... this is on jaybobs 7/8 with the .29 kernel, with background data off. And my regular usage which is not a lot. but for me its good. i wish I had tried it ages ago.

I believe that you can set the ramp up frequency and that may help with the lag. Setcpu, advanced settings, I think?

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.

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.
Sent from my GT-P7310 using xda premium

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.
