Thumbs down Nvidia cold bug?

My 7800GS EE runs like 50fps and 20fps then crash in aquamark3.. but only when its really cold
when my temps are int the 40C range it runs perfect but yet I put it int he window and get temps of 33C or lower it sucks.. Whats the deal? Is there something wrong or does it not like cold temps?

Trust me, 33C or slightly lower will not bring the cold bug out. If you were running -20C or better, we would talk. You are not in the ballpark to talk cold bug, as a matter of fact, you are not even in the same universe.

Sorry to prove you wrong BA, but just search google and see what comes up...

7800gs cold bug - Google Search

It seems the 7800GS series does have a cold bug, caused by the core throttle control wrongly thinking the card is overheating when it goes below ~38c, and therefore throttling the card waaaay down.

Please re-read my reply, then read your response again. Try it sober.

Hit me up on MSN. I will mod the bios for you to fix the cold bug

BA sorry but you're not sober. The bug is real although I have heard it happpening from 35C to 25C. The AMD cold bug on the other hand happens anywhere around 10C to -40C.

With the help of Cpt.Planet It doesnt not have the bug anymore!

I'm confused. And I don't drink so I wasn't drunk either when I replied to that post.

Did you misread the tilda as a minus? I put a tilda as meaning 'roughly'.

Read the original post. He was talking about the cold bug at 33C, not -33C. It seems you assumed I was talking about below zero temps. Killert was asking about the cold bug hitting him at PLUS 33C, not MINUS 33C. Understand?

EDIT: CPT P, you need to learn to read better also. As far as my sobriety goes, the less there is the more it enhances my ability.

Maybe I can help...Reflux was saying that the bug would hit approximately around 38, not negative. He used the ~ key and not the - key. I think that Cpt. Planet was only trying to clear that up also. The important thing is, it is sorted out and killert got his problem fixed.

ROTFLMAO...wow.....he's hit a new low that even I marvel at!!!!

Interestingly enough, despite being proven wrong and/or being corrected by two others; you STILL can't admit that you were wrong; which only confirms my theory.

yay.

On a more important note, good think that Cpt. was able to help fix that problem.

I'm surprised that nVidia would have a bug like that. I also wasn't aware that AMD had a similiar bug as well.

What's also more important (or interesting, at least to me anyways) is NOT being a ECE, why such a bug would exist. (looking at the CPU/GPU from a purely signals perspective.)

Hmm.....(too bad that that's not my area or expertise, although it's still intriguing to me nonetheless.)

Here is the original post. Can anybody show me a minus sign or a tilde? Please, I would like to know if I missed it.

Alpha, you are an ass. I wish you would have read the first post before you attempted to make fun of my reply. Then you wouldn't look like such an anus.

DW, I am dissapointed that you didn't look back through the posts before you made your "funny" post.

Ive read this thread more than 5 times over and still don't see what the confussion is.

Killert suspected there was a cold bug in the 7800GS when temps get below 33 centigrade (thats +33C above 0).

BA disagree and said you won't get a cold bug unless you go into negative temperatures.

Reflux corrected BA, and confirmed that there is a cold bug in the 7800GS at around the level that Killert original suspected...

Agreed...I thought that there would have to have been a mention of phase change or such before any assumption of killert going to -33...

Well, BA, to answer/address your concerns:

first off - I DID read the original post. I made my response brief enough such that it'd be able to keep your attention for the brief moment while it lasts.

If you READ it, you would have found that I wrote that it is a very interesting problem and I do not fully understand how it happens from a ECE perspective as it is not my area of expertise.

The question isn't in where there was a tilde the original post. First off, no one can even measure the temperatures exactly! Therefore; there is already error introduced into the actual measurement which makes the temperature BEING 33C to approximately equal to 33C (i.e. ~33C).

Something that you would have known if you have ANY clue about measurement devices, in particular, digital measurement devices, temperature and the measurement of, and numeric computation/numerical methods.

(go do some reading on trunctation error)

Second - in your reply:

That was proved incorrect by a simple google search - which I am CERTAIN that you had already done prior to posting that result.

If the cold bug didn't exist, then why would killert POST about it in the first place?

and if THAT is true, then why would Cpt. had to assist killert with a BIOS flash to correct that issue?

That's the second indication that invalidates/proves contrary to your statements.

Third - you failed to address the results from a simple google search on the topic, nor did you address to reflux's remark about "sorry to prove you wrong". In addition to that, you offered no help, or advice to solve the original issue, to which, you are so keen/apt to direct people to re-read without offering any form of resolution to the question/topic at hand.

So, in bringing the question of soberity, not only did you contradict yourself, but also raises question about your own soberity.
