CPU Vids

[Guest2]

Can coretemp reported vids on Q6600 chips differ from motherboard to motherboard? A while back I tried a Q6600 on an Nvidia based board and then an Intel one and the VID stayed the same.

I bought one that was supposed to be 1.265, got it fitted and is reported as 1.35. The seller had this to say

"Hi. Like you asked me to I used the core temp program to find the vid of the chip. It stated 1.26 on my old board. This board was an xfx 780i. Would this make any difference? I don't know! In real temp it said its lowest was 1.25 and highest as 1.32 like you have said. But I have given you the one from core temp which seemed right being inbetween the low and high"

With VID there is no going inbetween any low or high? Do you think the seller has possibly got mixed up with the voltage as it lowers and increases based on load? I would like to think this instead of him trying to sell me a higher VID on purpose, in the hope that I do not find out.

no-one have a cpu vid then, or know if they change?

 

[Sukh]

I don't think they change. I thought they were set at manufacture.
Is he talking about vcore?

Based on his claim that Real Temp went from 1.25 - 1.32... sounds like they were looking at current voltage instead of the VID

Yeh thats what I think he has done

It clearly says 'VID' in coretemp. It also says core voltage, but I didnt ask for this

What you have to decide now is, do you think the seller was mistaken (noob), or a chancer, if a noob, you may want to let them off, perhaps a part refund?
If the latter, then you should be looking to return for a Full refund.

Did the seller not give you a screenshot of Core Temp?

I had a new case arrive at the same time so when I got home I spend a good hour and half lapping the CPU before installing it. Once installed I noticed it was 1.35vid and not 1.26. It wouldnt boot at 3.6ghz as my other one does with 1.56 volts in load. I increased upped the vcore a bit and it booted and primed for 5 mins at 3.2ghz

So, viable options are to either send it back for a full refund, however as its lapped he could think I am sending back a different chip.

Either way, I will probably be leaving something negative in feedback stating he send me an incorrect product as its been a waste of my time

 

[Sukh]

Hmmm bit of a sticky one, was he a business seller?

 

[UKDTweak]

Ouch! you lapped it before you even tested it was working?
Shame, looks like your stuck with it or sell it on, hopefully not lose to much in selling it on?

Yeh, I presumed it would be what he said it would be. Like buying a ferrari and getting all the clothes and then a metro being delivered to me! (not that I would ever buy ferrari clothes, or any other make of car)

More annoyed at the seller, I presume hes not a numpty but cant see how he didnt notice 'VID'

Dont think he is a business seller, it was on here

If you bought it on the basis that you were getting a low VID chip I'd get a refund tbh.
A q6600 with that VID is probably only worth £65 seen ones with slightly better vids go for around that price.

I have seen a few people do that in the mm claim it's a VID it isn't !

If it were me personally I'd be furious and leave negative feedback if the seller didn't offer a refund.

If for example I paid £85 for it on the basis it has a low vid I wouldn't accept anything other than a full refund or at least £25 refund and i keep the chip 1.35 VID 3.2 ghz q6600's are worth no more than £60.

If anyone cares to dispute that at least 10 bad clocking high VID G0 Q6600's have sold for that in the last 6 months.

If it was on here and not ebay I would ask for the difference between the average price of a poor clocker and the price you paid as a compromise.

Maybe email a Don or something?

 

[Guest2]

Maybe give the option for a £25 refund based on the fact its not the VID stated, or ask for a full refund?

I dont like leaving negative but this has already wasted my time. If neither of these are met then maybe I will

 

[pastymuncher]

You would have more leverage if you had'nt lapped it. You should always make sure things work before doing anything to them.

 

[iNPUt]

Lucky me, offered on that chip, not sure you really could ask as much as £25 since that would be valuing the chip at £60. Maybe £10-15 part refund then chuck it back up for sale with the correct VID and you should break even / +£5 to cover postage. Wouldn't leave negative feedback, maybe neutral since he gave the wrong VID, contact the seller see what he has to say about it.

VID will be reported lower when speedstep (or EIST, C1E, or whatever kicks in on these 775 boards) is downclocking the CPU.

My 1.2125 VID Q6600 reports as 1.1525 when speedstep drops the multi to 6x.

Of course, you're only really interested in the VID at proper stock, not when speedstep is downclocking your chip.

There's a couple of conflicting definitions of what vid actually is.

Overclockers tend to take it as the voltage cpu-z reads when the system is at stock settings. This is a function of motherboard and whether vdroop is currently allowed or not. And, as above, probably of power saving features. Certainly it'll change with load as well. This seems to agree with Intel however, that there is some default voltage burnt into the chip during initial testing.

At least a few documents I've come across consider it to be synonymous with core voltage / vcore. This makes the most sense to me considering the above.

On another note, cpu-z is likely to disagree with a multimeter, and speed fan et al may offer completely different values to either of them.

Finally, low vid => good overclocking is at best a correlation. There's a competing low vid => runs hot correlation too. There's no known causal relationship here. Or at least, I'm yet to come across any document showing statistical significance for either or a reason to believe low vid is a good thing. Beyond the inevitable hearsay anyway, I'm sure someone will shortly tell me that out of their sample of two high vid chips, neither clocked very well.


Personally I'd rather pay a premium for a chip that hasn't been overclocked, so would likely buy from someone who has no idea what vid is. I disagree with the belief that temporarily high voltages/temperatures cause no damage, however this is the consensus meaning people are under no moral obligation to mention what abuse the chips been through before the sale.

Suppose my rather longwinded point is that it probably doesn't matter.

edit: speed step <> speed fan

I have just enabled speedstep, EIST and C1E, booted my computer and it clearly shows the VID in Core Temp as 1.35. It does not move when you enable C1E and EIST

edit - I received a couple of replies from the seller...


Seller - I'm not taking it back as you have lapped it. Sorry no way! I will give you a tenner refund. That's my only offer on that I'm afraid. I did what you asked. Core temp etc. Its a genuine mistake. And seeing as though you have in all damaged it by lapping it I think it then should be your responsibility to move it on. Stick it on the bay! Check my trust out its all positive all my transactions have come in the last couple of months really and there is no suspicion of any dodgy dealings there. Its up to you mate but my stance is quite clear. You have been very honest about the lapping which I appreciate. Its one of those things I'm afraid.

My Reply - Yeah, I understand about not wanting it back because its been lapped. Would
you be willing to refund £15 then I could at least try and get £70 for it
(plus about £6 in fees) meaning I would have only lost a few pounds. I
know you have good trust and it will have been a genuine mistake

Seller - No ten it is! I'm trusting you here that my chip is actually what you say it is! I would have taken it back for a full refund if it hadn't been lapped. I run a multi million turnover supermarket so I know about customer service but in my eyes the chip is damaged now so I wash my hands of it.

Me - please sent £10 paypal gift to .......
I will leave feedback after the money has gone in

Seller - As you can see after reading your thread I'm vindicated so no payment I'm afraid! Read strumpusplunkets post. Sorry Alex but I knew what I sent you was correct. I'm glad I just read it or I would have beern a tenner lighter.

Me - I have just enabled speedstep, EIST and C1E, booted my computer and it
clearly shows the VID in Core Temp as 1.35.

The more emails I recieve from him, the more I feel that he has sold me a chip with a higher VID when he knew about it.

 

[Sukh]

I've never seen VID move with speedstep either :S

You should have checked before lapping.
