Bad i7-2720QM?

Hi, I've been digging around the forums and google for a few weeks duo unsuspected crashes of my new Clevo P150HMX. I've stumbled upon this. I guess I should just return it next monday but I've done a few benches and comparison to give some more info.

HELP
Can someone with a normal i7-2720QM Post pictures please ( not ES ). I want to straighten things out b4 i RMA it.

 

Stability Tests

Prime 95 @30min no crash/error;
IntelBurnInTest @ standard No crash/error;

IntelBurnInTest @ maximum No crash/error;

IntelBurnInTest @ Standard + Furmark running = Stable. Except when the programs stop and the load drops and it's starts downthrottling I'll get a light blue screen ( Not a BSOD) and have to hard reset.

Pics too small to really see but if you have an Eng Sample chip even if its same spec/step/ect... as another does not mean they are identical.

This is one of the downfalls to ES Chips. Some have been modified/tweaked special. Yours looks like it’s got some features disabled which probably means it was a chip that was going to get pushed hard or tested until it was killed to see the limits or something.

If you can return the chip I would say do that....

 

Sorry, thought those pictures where clickable, if ur still interested.

Yes, some features are disabled and mine goes far beyond the 45W TDP.
No TM1 /TM2. I'll try to edit the pics.

 

My laptop had an 2820QM (currently had to send laptop back because defective) but the first day I had it I was able to go well over its rated W myself.

I was like 10-15W over. I was not to worried about the CPU doing that because its pulling it so its not the same as over voltage but what worries me is the PSU...

I had the 2820 & 580M and watching the power usage between the two they pulled almost 200W and yet the PSU is only rated at 180W so makes me think PSU will die soon from over taxing (another failure of testing on clevos part).

Anway I would not worry about the power usage being it matches what I saw with an oem chip, but the fact that it has features disabled maybe. Looks like some of them are the temp monitors which might mean if it overheats it wont shutdown the system as it should but that it will just cook itself and possibly the mobo.

IF your laptop is on the latest bios (to ensure all features are enabled via BIOS) I would say see if you can exchange or return the CPU.

Not really much else you can do past that. I know the older bios had some things disabled but at this point on latest ones everything should be on.

Good luck on all that, I know it sucks, kinda like me spending almost 3k on a laptop 2 months ago and it being DOA on day 1 and sager just wanted to tear it apart and swap random parts instead of giving me a new one... :/

 

Yes I've talked to BTO Tech myself and he said I should ask for an replacement and I should get an i7-2720QM OEM. They are obliged to do that or so, so gotta wait till monday to contact my reseller.
Though I'm interested How did u measure the -W ur GPU pulls, as I'm interested in this too. Just to make sure my PSU isn't under heavy pressure and duo to fail very soon. Ergo my Battery has already reached 3% Wear after lets say a week.

 

Not sure how accurate it is but I was using everest to look at usage. It seemed to work well on desktops I have had.

This laptop is the first machine I have had that has shown in it to go over th manufacture listed spec though on power.

If you have a 100w GPU (which in my case shows as like 115W when maxed) I would say you are in same boat as me. PSU will not last the best.

As far as battery, thats normal. I would not worry about the battery being any more strained because these darn GPUs lock themselves so low.. If the GPU could run at full spec on battery you would get like 25-30 min of life. eheh.

I am waiting for bios editor to support GPU so I can mod it. I want my GPU to run at full spec on battery but not to game on battery full time just so that if I need to get online with a MMO for a few min I can actually play until I can get plugged in or something silly (though this is another topic on its own).

Anyway if you can get an OEM CPU you will be good. I hope the best for you on that as the laptop seems like it could be a great machine though I dont know as mine is DEAD and makes me hate sager right now. lol

 

I had the same problem as you. Originally had a 2720 ES and it didnt bench properly either. From what I can see theyre basically a dud batch of ES chips. If you monitor the turbo on these chips they dont hold speed...they fluctuate like mad under load - that's why you are getting those horrible bench scores. If you play games that are CPU intensive like SC2 you will notice stutter too. That's when you really know your CPU cant hold the turbo. Throttlestop doesnt help either.

I eventually took mine back and upgraded to a qualification sample and it works great. It's a bit more expensive but also a lot more reliable as it basically is a retail chip.

BTW - the red out on the thermal monitors in HWinfo is strange. My QS chip has those functions red too but my thermals are absolutely fine and I can check them too. So I don't worry about that too much. Another thing to add, the ES not working properly is absolutely nothing to do with power draw. The dud ES seems to not be tuned to draw the right amount of watts - that much is correct. Another reason to get rid of it.

Good luck with getting your replacement. Like you I thought the 2720 ES would be great as it has 8MB vs the retail 6MB. But it's far far worse than a properly functioning 2720 if you have a dud!

 

I've a hard time understanding what you mean by "dud" I suppose u mean me ? Also I've ran SCII this weekend and yes u are right I never reach the 3.3 Turbo more then 1 second, though It can stay on 3.2 Forever. Also the strange power settings were there because it was manufactured to put under heavy stress until it fails for testing purposes I guess. Als a problem with downthrottling causing my notebook to crash. I'm returning it today and hope to get a replacement. As the programmable TDC + TDP and Unlocked TUrbo modes and Thermal Monitoring seem awsum if u want to somehow OC it or put it under heavy stress. I don't think it'll match with my AMD 6970M and the 180PSU.

 

You cant OC with the chipset in your laptop anyway so its not really relevant. Sorry Im English so maybe I have some weird expressions

Dud just means you have a bad chip, bad product etc. Youre not a dud! Maybe a dude but not a dud

 

Oh okey, well after 2 months of RMA of having GPU issues, they still won't change the processor because they say it works but they won't send me proof or any results..
