• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

The accuracy (or otherwise) of AI

My HP desktop PC is 10 years old now. I'm reluctant to change it because all the saftware (apart of the OS itself) is also old, everything is of a generation. It all works and generally, apart from a few regular browser problems, all is well.

I put in a new SSD about a year ago and that has been fine and I (reluctantly) upgraded to Win11 a couple of months ago, but it all went smoothly.

The only problem is that it is getting a bit slow, especially when I'm editing video. So I'm thinking of upgrading the RAM.

Currently I have 8GB, so I asked Copilot how to find my particular motherboard (it's an 82F1, apparently) and what was the maximum RAM it could take. This is what it told me:

The HP 82F1 motherboard can support a maximum of 32GB of RAM. It has two memory slots, so you can install up to two 16GB RAM modules for optimal performance.

That is not correct. According to several vendors and HP itself, the max is 16 (2X8) GB. So where does this machine get its information from?

I've just installed Resolve to see if that makes editing easier - I need all the RAM I can get.

It doesn't. These language models don't have a concept of actual information or knowledge, just what words appeared together in its training set. If the question you ask is something that was directly answered somewhere in that training set then this is usually enough, but if it isn't then it's incapable of saying "I don't know"; it just makes up something that looks like it has the right sort of words in it to be an answer to the question.

In a sense we've come full circle on this. Before the Internet, if a child wondered about something, they'd ask a parent or other relative, who wouldn't know the answer but would make something up to sound authoritative, and the child would file that away as the definitive answer to the question until they discovered otherwise decades later. Then Google came along and you could find the actual answer immediately, so people didn't need to make up plausible sounding nonsense so much. Then ChatGPT arrived, and now when you ask Google the first answer you get is... a machine that doesn't know the answer but makes something up to sound authoritative, except now it's "Google says ..." and not "uncle Dave says ..." so people are even less likely to question it.

If you're ever in doubt about how much to trust its answers, I refer to the following classic example which has been posted many times online before, but it still produced for me just now:

probably not a bad idea upgrading the ram, depends on the price, I find higher clock speed CPU both single and multi core speeds makes a huge difference, you also want a decent GPU for video editing, if that's upgradable then I'd look at improving that as well.
 
Thank you.
I don't know whether my existing RAM is DDR3 or DDR4, How can I find out and if it is DDR3, can I install DDR4 instead?

PS The trouble with all this upgrading is that it can end up being a bit like Triggers Broom...

It's currently an NVIDIA GEForce GTX 1050. I don't know if that is a separate graphics card or if it is built in to the motherboard.
20 years ago I knew what I was talking about with this stuff, but I've been to bed since then.
 
Is it really worth it Steve? Bedrock are doing entry level gaming PC's for £190, £490 for one with i7 and significantly better spec than you have now and a Dell Inspiron is maybe £600 if you shop around and will have a pretty good video card, fast clock speed etc. Latest Windows on board etc, guarantee and should last a good long time.

We've just built a silly spec design PC for offspring for professional CAD work and that cost quite a bit more, but you don't need that spec.
 
You make a good point, Adrian. But these days I belong more and more to the "if it aint broke, don't fix it" school of though, so I'm trying to change as little as possible. As I say, it is all working reliably, if a tad slow. A bit like me (except for the reliable bit...).

Hi Steve,
If you use perplexity AI, along with the answer, it gives you the source that it found.
