how bad ram affects dvd burns

Recommended Posts

Recently I did a ram test with memtest, that reported an error.

So my question is: could it affect my burns, and how?

 

Sometimes, while verifying a dvd, just after burning it, imgburn shows an error.

At a second verifying attempt (Verify Against Image File), with the same drive, it seems the dvd's fine (no error messages)...

Could it depend on the bad ram? And which of the two verifying should be more trustworthy?

 

Thanks in advance

They're the same function so it doesn't matter which one you use - verify after write or the standalone one.

 

Bad ram would give you miscompare errors.

 

 

So, if I got it right:

- Bad ram could affect only the verifying process (and not the burning process).

- Even if i get a miscompare error, the dvd could be fine, and the error message may be because of bad ram.

 

If I don't get any message, can I be sure that there's no miscompare error?

(I'm asking this because, sometimes, at a second attempt i get no error, and would like to know if it's enough to consider the burn ok, even if "verify after write" was unsuccessful)

 

 

Thanks!

bad ram is bad ram, and needs to be fixed

 

Yes, of course, and I'll do it soon :)

But in the meanwhile i would like to know if i can continue to burn dvds relying on the imgburn verify process

(no miscompare errors, even if with bad ram, and even if after multiple verify attempts = dvd burned ok).

use this progam to look at your older computer and see if the temperatures and voltages are an issue?

 

your ram might be fine, same thing for your burner

 

 

Thanks for your suggestion.

I installed the program... Should it give an advise if temperatures and voltages are an issue?

I don't know exactly what to look for :(

 

Anyhow, any answers to my previous question are welcome! :D

No it's not just a problem with verify, *anything* that ever sits in memory is subject to corruption if it's faulty - this includes data being read from a file and written to a disc.

 

There's just no way of knowing that this corruption is taking place unless you compare it against a 'known' something (or of course if the application/computer just keeps crashing!).

So I assume that when I verify against an image, and imgburn gives me no miscompare errors,

I should be sure that the content of the dvd is exactly like the one on my hd,

apart from any possible problems with ram.

 

The fact that at first it gives me miscompare errors may be because of bad ram,

but if at a second attempt the verify is ok, i could be sure that the burn was succesful...

 

This would be give me relief :)

Yeah, I would have to say it's very unlikely that the burn and the verify would both be corrupted at exactly the same spot, therefore if the verify passes it's fair to say the disc is fine.

 

If Verify fails once with miscompare errors and you do it again and it passes, the first was probably due to bad ram and so again it's safe to think the disc is fine.

 

If in doubt, take the best of 3!

Great!!

That's exactly what I supposed, but I wanted to hear from you!! :D

What do you mean with "the best of 3"?

Thanks again.

Verify it 3 times!

 

Compare any miscompare error addresses and take an average.

 

 

Ok, even if, according to what we said earlier,

 

if I get no miscompare errors at the first verify, it would be useless to verify the dvd a second time.

 

And if I get no miscompare errors at the second verify, it would be useless to verify the dvd a third time... and so on

 

 

Don't you think? :)

You shouldn't really be in a situation where you can't trust your PC's memory.

 

I'd concentrate more on fixing the ram issues right now than verifying discs and hold off on burning anything else until it's sorted.

 

 

Anyhow, maybe I just worried too much about my RAM, probably it was just a false alarm...

 

memtest gave me errors in my RAM at the first pass, just after a few minutes.

 

Now I'+m testing it with memtest86+ , which seems to be more trustworthy: I'm at the third pass and still not getting any errors...

Don't forget that Microsoft made one too.

 

Give that a go when you're done with Memtest+.

 

You might want to enable the advanced tests though because the standard ones are done with pretty quickly.

 

If you're running Vista it's an option in the boot menu (maybe press F8 if it doesn't appear automatically?). Failing that, just download 'windiag' from microsoft's site.

I would give the computer a good cleaning and update my bios and retest the power

 

I always keep my pc quite clean...

As regards with bios update, I admit I've never done it, because it seems quite complicated (even just to find the correct update...)

 

 

try to get a cpu temp reading?

Is it normal!?

It may be 127F, which is not all that bad (this is 53C = the temp my PC runs at under continuous 100% load).

 

127C and she's a goner.

 

Anyway, his Everest temps and voltages look OK, although I am a bit sus on those memory timings even though they are the SPD ones. I run faster RAM (Corsair PC3200) and only run it as 2-3-3-6. Also, his CPU Core voltage is just a tad high for mine. 1.40 is where is should be. I wonder if his PSU is on the blink.

 

Regards

It's strange since the other temperatures are in °C

But of course it's more than strange a 127°C temperature and the pc not exploding.
