E6400 overheating throttling

Interesting. I thought my system wasn't affected by this underclocking, but I checked the Event Log and Event ID 37 (7) does show up occasionally. Though, the underclocking never lasted that long, the longest I could see was only 77 seconds.

 

So you don't foresee any future consequences of disabling Dell's throttling?

A half-multiplier is only relevant with 2.53 or higher for Penryn, right? So a 2.4GHz won't become a 2.2GHz, etc.? So you could do the undervolting and the throttling disablement both in one profile?

I was under the impression that, for some users, the throttling could occur even without pushing the notebook. I just read the title of the thread over at the Dell forum "...Overheating issues with minute tasks such as playing flash videos for extended periods?" So I figured since some users aren't even experiencing these issues while playing games and some are experiencing them just by watching flash videos, there must be some variability in the bug's severity.

Thanks

 

I'm seriously considering buying an E6500. I would prefer integrated graphics for a cool running system and long battery life but this issue is a concern. Is it safe to say that all E6xxx systems with integrated graphics are affected by this bug?

 

The Quadro NVS 160M is a cool running GPU. It's not a gaming GPU, but not Intel one... it sits in between both worlds (light CAD and light gaming). The metal base is used as a heatsink as well to ensure cool running. The only downside that would be visible, would be a slight reduction battery life. There is a battle on the clear answer between real world, and calculated; I say ask Dell, or view the great battle in the 350-450 about (somewhere there) page of this forum section:http://forum.notebookreview.com/showthread.php?t=293401&page=440

 

Well, in response, I'll just reiterate what I've already posted (sorry to be repetitive, but I can't think of any other way to counter the myth being propagated that this problem doesn't affect E6X00 NVIDIA users.)

I'm an NVIDIA user and I absolutely do have the problem in a pretty bad way. My 59-page report describes my problems in excruciating detail (and explains much detailed technical background about how the problem occurs). It seems many other NVIDIA users have this problem as well (some with E6400's some with E6500's). For example:

Just because there might be more Intel graphics users reporting the problem than NVIDIA users, that may only mean there are more Intel systems out there than NVIDIA systems (which seems a logical conclusion given that the NVIDIA Quadro NVS 160M discrete graphics chip is a higher-cost premium option).

 

It's not safe to say that unless Dell says that. But I've scoured all the forums I could find on this and I'm not sure I've ever come across any report of someone saying "I have an E6X00 system with Intel graphics and I have done all the testing necessary to confirm that I most definitely do NOT have this defect". But then again, if there was such a person, what are the odds they'd post to this forum (or even come across it in the first place).

Bottom line is the jury is still out.

Sure would be nice if Dell would weigh in on this somehow one way or another (either publishing something or even just to one of us poor slobs who are calling them about this problem). The longer they remain silent, the fishier it smells.

 

A quick note about the Quadro NVS 160M- the E6400 has the DDR2 version, while the E6500 has the GDDR3 version. The difference is substantial- the E6500 scores 35% higher on 3DMark06 than the E6400. Just FYI.

 

I never understood why the E6400 doesn't have DDR3 GPU memory, if still true for the E6500.
Either-way, 15inch is not what I would call very portable. I think the best deal right now is the Mac Book Pro 13inch.. I mean similar performance, less expensive, more or less the same quality, add Windows to it and you are set (just wait for the matte screen option), and you have a better GPU. But, I go off topic here.

Based on what was reported here, the benchmark score of the E6500 is 1943 for 3D mark 06, I have (without overclocking) 1823. It is 120 point different.. which is not much.

@tinkerdude!, you said that Nvidia users are also targeted. I wonder, if you know, do they have the Core 7 error, and if they are using Vista/Win 7 64-bit?

What I wonder is if, the problem for Nvidia user is a driver bug of sorts, and not hardware level like the Intel issue?

 

I strictly use XP. There's no equivalent to the Vista "Event 7" error on XP - I get no such thing or anything like it in XP's Event Viewer.

one4spl, from another thread, back in February (when it was summer in Australia) said he/she had an E6500 w/NVIDIA and had the problem under Vista, Vista 64 and Windows 7. The posting is here.

It hardly seems to me that the source of the problem has been determined - could be hardware, could be software. In fact, to me it seems likely to be a software problem for all cases, but no one can be certain yet. How are you so certain it's a hardware problem for the Intel graphics case? Are you sure you're not jumping to a conclusion prematurely?
