E8400 stuck sensors RMA:"Works fine for us." That possible?

I recently bought an Intel E8400 E0, and like many other E8400's its temp sensors were stuck. So I decided to RMA it. My supplier sent me an e-mail saying they tested it and it worked fine for them, so now I need to pay for testing and shipping. I was wondering if this is possible, for stuck sensors to suddenly start working. Had some bad experiences with suppliers just flat out lying to me when I RMA'd something in order to avoid giving me a new part saying it must be my system that's the cause, happened several times.

Now I do not know what board they tested my E8400 on, but I'm using a GA-P31-DS3L with the latest F9 bios which supports E0 stepping cpu's. And I've been unable to find anything on the internet that indicates that stuck temp sensors is common when pairing an E8400 with a p31-ds3l.

So can stuck sensors really just suddenly start working again or is this e-tailer just lying to me.

As far as I know, they only test the chip to see if it works, not the sensors.

But it MAY be your motherboard.
Thx for the reply, but they stated they did test the sensors and that they were working fine.
Honestly, they probably didn't even check the temps to realize that the sensor is stuck. They probably just stick the CPU in a system and see if it boots, and since it does boot they say that it works fine. I sent back an 8800gt to XFX because it ran way too hot and they told me that they tested it and found nothing wrong. They replaced it anyway though and the one I got back ran way cooler in the same environment, so the first one definately had an issue. The point is they obviously didn't check its temps when they tested it or they would've saw the same results I did. I wouldn't pay them anything though, I would reply to them stating the exact problem you have with the chip and challenge them to prove that it's working fine. I don't think they're neccesarily lying to you, just not testing the chip thoroughly enough.

Wouldn't that be considered lying if they claim to have tested it?

Not if the workers are just lazy...Which is most likely the truth.

Meh, I suppose

I agree. Perhaps they just need further clarification to understand. After all, their minds are probably dulled from the day-to-day work they have to do. So, I say it's time to wake them up and say, "hey, please run this chip in Windows. Then open up Real Temp and give me detailed results of your findings. Here are my findings, and they show that the sensors are stuck." I'm sure that they're just sick of the same old crap day in and day out and would rather not put any effort into this. So, show them that they need to wake up and pay attention.

So, is it possible for stuck sensors to suddenly start working again or not? If it's possible they're not necessarily incompetent liars, I haven't received the E8400 back yet since I have not paid the bill yet so I can't tell at the moment.

Oh really? Wow, great. Why don't you fax me the screenshots of the idle and load temps so I can see how it's working for you?

If they are willing to do that, you should pony up a reasonable fee (if they agreed in the first place). If not, then you have no way to know their not BS'ing you.

Sensors which bottom out below 50C are not a valid RMA reason anyway.
hell. my temps sensors dont even read right.
One of my temp senors on my e8400 is stuck at 40 but the other works just fine. If both aren't working I would call that a valid reason to RMA, just for the danger of not knows at least the general area of your temps. Your cpu fan or w/e could quit on you and most likely wouldn't know until it's too late.
customer is always right. always.

I would not take no for an answer......and if your having trouble because hes a good talker, put it to the bottom line and spell it out for him......Tell him your not the average customer and you know that the sensors are indeed stuck.....and if he doesn't want to rma it, say you want your money back and your going to a new supplier for now on. simple as that.....since he runs a pc business I'd expect him to have half a brain and realize not to let that happen.

and no sensors would not magically fix like that...chances are zero to none lol
Sensors stick below 60c they usually work just fine above that. If they tested it to the thermal threshold then they probably did work.

Good point. I agree that they probably just tested it with 100% load and then said, "yep, they work just fine". But that's likely true. For example, my sensors cannot go below 33°C, but they work just fine once the temps go above that. So, as long as I know what the temps are when there's load, I don't care one bit.

Here's a quote from Real Temp's Results window that comes up after clicking Test Sensors:

Quote:


Intel has designed and calibrated these sensors to accurately trigger thermal throttling and thermal shutdown and does not recommend using them to report idle temperatures.

But, I say that this makes sense since it's really the load temps we need to watch, not the idle temps.

agreed the under 55-60 range sensors wont move sometimes......BUT.....the question is.....do they do that on his cpu?

my 3rd and 4th core sensors only start reading once they are at like 55ish and then only do they give readings of like 3-4 degree intervals....
When testing a sensor that must report accurately throughout it's range then you would want it to work correctly. If you are testing an upper limit sensor then the bottom of the range can be off or fail completely as long as it is accurate at the upper end. These are upper limit sensors plain and simple. We just got used to using them as a monitor. You shouldn't use a high level float that doesn't even reach the bottom of the tank as a level sender. But this is what we do.

Whoa, nice analogy.

my e8400 has one core sensor that sticks at 40.

above that, it works normally, reporting accurately with the other core.
