ThinkPad W510 Can you Overclocking with i7-920XM

At the config on the brink of thermal shutdown I got 100 C in 3 threads/cores. and 97 C or 98 C in 5 other threads/cores. The answer would be 2-3 C.

 

My W510 with i7-920XM connected to a Dell U2711 (27-inch) monitor had two thermal shutdowns yesterday; and it prompted me to inspect the reliability of my overclocked system. I did several rigorous tests from 6 pm to noon of the next day, conducting a lot of repeated Full System Stress Tests. Here are the findings:

1. Overclocked configuration can survive at most 5 rounds of repeated, automated non-stop Full Stress Tests

2. Non-overclocked configuration can survive 20 rounds of repeated, automated non-stop Full Stress Tests.

Turning off ThrottleStop does not reset the overclock setting. I needed to restart Windows to reset the configuration to its original settings.

Summary:

If you are working on something serious and need full reliability of your machine, restart Windows and do not start ThrottleStop at all before starting your work.

Overclocking is fun and exciting, though!

 

Hehe. Sounds cool? Maybe..

 

thitiv,

What SSD Drive are you running and whats speeds are you getting?

 

hi guys,

Im on the way to upgrade my w510 to 920xm or 940xm...
For what reason all of you bought the 920xm and not the 940xm one?
On ebay they sell the ES Versions vor 240 and 300 Euro.
I would buy the 940xm but Im not sure if it will be overclockable the same way as you overclocked the 920xm...

I am now using a 256GB Crucial M4 as primary and another 256GB Crucial C300 as secondary in the Ultrabay. Typical sequential read/write speed is around 200-230MB/s.

I just traded my W510 + 920xm in with a W520 + 2820qm. A 2920xm is still too expensive for me and I don't know whether an "ES" is reliable. Please share with me your experience with W520 as well.

@rionale, a 920xm is significantly less expensive than a 940xm. Both can be relatively equally overclocked.

 

I haven't used my W520 in few weeks. I am rather disappointed that it's not overclockable. The TRL AND TDP are locked. I geekbench around 11700..if you are wondering. Do you know anyone who can hack the Bios? I have a feeling that the W520 runs much hotter..and overclocking might be very limited..but I am willing to see how far we can push it..if we can get a unlocked bios.

 

No wonder why people are upset about the 2920xm on W520. My W520 + 2820qm geekbench around 11000! There is someone on the net whitelisting the BIOS. They should be able to do the same to unlock the o/c.

 

The 2820qm..well worth the price..

 

Did you buy the "ES" or the OEM version of 2920xm, by the way? The clock speed of the ES lower than the OEM one. But the price on eBay is significantly different too?

 

OEM. I am not sure about the ES stuff. It's probably worthless to get the ES..if we cannot get the bios unlocked..

 

That's sad. An OEM 2920xm gives similar geekbench score compared to a much cheaper 2820qm!!

 

Fine I bought the 940xm for 70Euro more... Im now wondering how to overclock this in the right way... I did the same as shown on the youtube video but I only get 7000 Points with same settings. Is there any guide how to overclock the i7 with thtorttlestop. I changed the TRL to 36 / 34 / 30 / 29 but the Monitor never shows an higher FID then 15...

Time ago a bought a qx9300 for my W500 but the Cpu doenst got recordnized. I searched the web for someone to hack the bios, found a few forums and websites. But on one of the "experts" ever did anything, even I beted 300 bucks... I think there is no way to hack the bios in that way.

 

You need to increase the TDP values. See our older posts for more information. Use a decent thermal paste, like the Arctic MX-4. It will allow you to push the TDP values to some higher limits. Believe me, this thread is the most comprehensive source "in the world" on how to overclock a W510 with i7-920XM/940XM!

 

Thx.

I set TPL to 75/65
and TRL 34/32/30/28 and geekbench scores @ 7600
what is wrond some pages before someone got over 8000 with lower TRL´s...

 

Actually, I think anywhere from 8000 up the system gets really unstable. If you run intensive tasks, you will get thermal shut down. So be careful save your work often.

 

for sure, but with same settings Ill have to reach the same score or not?

 

To get 8000..I am not sure you will have to play around with throttle stop. Increase TDP, TRL and Geekbench. Then Test the system with Lenovo stress test..keep eye on the temps. If they reach 100 fast without completing the test then..it's not stable for very heavy usage. At 8000, on my w510 it wasn't stable..it would often fail the stress test and BSOD. To find the sweet spot you will have to do some testing with your setup. Try our setting..and increase and decrease, come to a stable point where system won't fail the stress test and runs smooth.

 

With TPL 74/65 : 29/28/22/22 I 7062
even with much higher values like
TPL 80/75 34, 32, 30, 28 I dont break trough 8000...

 

Notice your multipliers 34/32/30/28. Watch also the actual clock speed in ThrottleStop. You would rarely go beyond 3.6 GHz or 27x. The math is 27 x 133 MHz = 3600 MHz.

When the CPU gets too hot from running at high clock speed for an extended period, it will throttle down, i.e., it will decrease its clock speed, to cool itself down, automatically. I'd call this a "relaxation."

If you let the CPU runs too hot by putting too much energy/power in as seen by higher TPL values, the CPU will get too hot faster resulting in more frequent automatic relaxation and degraded overall performance.

 

Finally I understand it... The multiplers I set are not fixed, the cpu can go down if it run too hot.
Ill give this an try later. what are you best undervolting values?

 

I didn't change the voltage. I don't think the W510 BIOS allows it. We just played with the TDP and TRL values.

 

Hi,

I noticed something strange... when I setup throttlestop 4 cores @ 28 in normal use the FID stays @ 28 but as sonn as I put some load on the cpu it falls down to 19-20...

whats wrong?

2nd one:

I restarted windows and started ts in monitoring mode and scored 7900... I turned ts on and scored 6500...
There must be something worng

 

When playing around with overclocking a 920XM or 940XM, it is a good idea to download wPrime so you can fully load your CPU. I would set the multipliers to 25, 25, 25, 25 to start with.

Run 8 threads of wPrime and see what average multiplier ThrottleStop reports. Increase the TDP / TDC values and see if the average multiplier goes higher. It might be heat that is limiting your performance. You need to post some screen shots while testing or a ThrottleStopLog file so I can see what's going on and let us know what 32M wPrime times you are getting so you can compare to other users.

 

Hi,

here is a screener @ TDP 85/TDC80

 

Are you testing on battery power? The little ThrottleStop battery button says you are sucking 67 watts out of the battery. Doing this on a regular basis will probably reduce the life expectancy of your battery. You should not expect to get maximum performance out of a modern laptop when running on battery power.

When plugged in during the wPrime test, is the multiplier higher than 20? Your CPU might be a power pig and you might really have to crank up the TDP/TDC values some more. You are already hitting 87C so with your present cooling, you probably won't be able to go much higher. I think some of these laptops max out at about a 22 multiplier when fully loaded before excessive heat becomes an issue. As heat goes up, power consumption also goes up so you need to raise the TDP/TDC higher and higher which creates more and more heat. I think you can start to see the problem when hitting almost 90C.

The Alienware M17x-R2 with this processor can use a 26 multiplier on all 4 cores when fully loaded and maybe even 27 if the cooling is perfect. I don't think the cooling in the W510 is up to the job.

 

I need better cooling to let the cpu run longer on high multiplers.
Last time I overclocked a cpu was an old celeron 300 Mhz...
Ill try to boost up the cooling by installing less paste.

I have a W510 with 920XM, with stock thermal paste.
What are the safe multipliers I should use for overclocking?
