Re: i7-820 performance

2010-09-14, 18:50 PM

All of the settings are exactly the same -- for a minute there I thought I found the culprit --

I was the only one with hyperthreading enabled.  Had to be it right?

 

Turned off HT, still can't turboboost like Knight Rider.

 

Ah well.  Maybe I'll just leave well-enough alone -- i mean, 2 more years and maybe

i'll get a new laptop, right? :)

 

Thanks all.

lol, personally I'd find out what's wrong with it... I upgrade my notebooks every 3 years about the time the battery dies out.

 

Well I just got my W510 literally just now; it's got a i7-720QM so I'll test out turboboost and see how it goes.  But going to replace the CPU within the hour after that.

my i7-720QM turbo'd to near 2.8 once and I set my ThinkPad power configuration to basically max everything.  I just replaced the CPU to an i7-940XM and saw it boost to 3.2Ghz so I know it works.  I would really look into your power settings and change everything to max. Also try running something labor intensive like a game.

Hey thanks for your patience playersnoop.  Can you change the processors in any/all

W510's?  I have a 4318CTO.

 

I'm going to try to insert a screen capture of my batt settings.  I put every possible setting

to "Max" both in Power Manager and Windows power control panel -- and disabled timers.

 

As you can see the 2nd and 3rd row are never at max green dots.   Do yours show as all maxed

out?  Are there bios settings for power?

You are running a 940xm in the W510!? Does it not melt the system considering the many W510 overheating threads around?

outofstepper - well your dots look fine but no way to know the settings of each individual settings.  Make sure your fan setting is on active.  Also try running Windows Experience Index to see if your cpu boosts higher.  And yes you can replace the CPU on any W510, which is why I got the lower end one and upgraded the CPU myself since Lenovo is still selling the x20 series which is last years model.  If I was going to pay this kind of money I didn't want to settle for a 920XM.  Actually almost all higher end i5 and almost all i7 processors can be swapped since they are all PGA988 sockets; which are non soldered.  It's just that Lenovo actually allows for somewhat easy access to the CPU, "took me about 30 minutes from start to finish"

 

jket - yes I'm running i7-940XM on my W510.  Overheating is primarily due to the GPU not the CPU, I am actually running some tests on thermal compounds to see how much of a difference it makes.  As for my CPU temps idle is 31-34 deg celcius; normal is around 41; high is around 55-60 when playing StarCraft 2.  the GPU is about 10 deg higher than the CPU.  The HD temp is halfway between the CPU and GPU temps.  So the CPU overheating is the least of my worries.  Besides the x20 and x40 series are only 133Mhz difference between the two and doubt there'd be any big difference since Lenovo gives the option for the 920XM processor.

 

Right now I'm using a silicon based compound, was considering doing silver too but the GPU is so small didn't want it to get on the board, I'll be switching to carbon based MX-3 tomorrow for the final fit, and hopefully I can manage to drop 5 deg across the board... "hope" :)  Also when I took out the original CPU I noticed some sloppy compound all over the edges, good thing I was doing this.

Your thermals are awesome and also in stark contrast to the people stating that their W510 have suffered thermal throttling and even thermal shutdowns. Maybe Lenovo found a way to improve the cooling system. However, I now remember that someone on this board stated that one of the BIOS updates to the W510 resolved some of his overheating problems but instead resulted in lower FPS in his games (making him suspect that the GPU was being throttled or downclocked).

outofstepper good news... I think I found your culprit, mine started doing what yours is doing after I updated the bios today... capping my CPU to 2.4Ghz no matter what I was running.  It is a power setting but in the bios, you need to adjust your SpeedStep settings.  Go into your Bios, then Power, then adjust your SpeedStep settings for AC and/or Battery to Max Performance.  Hope yours is the same problem.

 

Now I'm doing a Prime95 stress test on my CPU to see it work plus some heat temp tests to make sure it doesn't go too far.

Player, my friend, you are good good man! (woman? person!).

The bios setting did the trick!  I'm consistently seeing 2.8 and a jump

just a few moments ago to 2.9.

 

How do I go about giving you 11 stars?

 

Thanks!

PS. my machine turbo boosts on the docking station with 2 monitors attached AND the lid closed.

At least for now it does. :)

 

PSS .. since I'm not one to leave well enough alone -- are there instructions available somewhere

on how to upgrade the processor?  is it something I could call in a tech to do? (i'm in warranty, and

i'd pay for expenses/time of course, just don't know if they'll come out like that on a 'whim')
