Interested with questions...

Sorry for the newbie type question:

Will switching my CV 64 from 70NS to 50NS video memory make a noticeable difference? I know this is a very subjective question, but I don't know the impact of it.

PM additional questions on shipping and availability.

It will make zero difference. The 50ns / 70ns only refers to the highest response speed the chip can handle. The card will not access them any faster unless there is a setting on the card to do so.

Made same experience with 35ns chips , zero acceleration towards the original chips , but may you can change the 50 MHz crystal with a faster one to gain some more speed ?

Hello,

replied on PM!

@all,

i remember a tool (software) to overclock some Amiga RTG Graphic card, on Picasso96 and CyberGFX, or to change a parameter on the icon placed on "sys:devs/monitors".
Exchange the crystal oscillator is trivial and not so intuitive like on a cpu card.

Pretty much the same as a Voodoo card: simply edit the tool types and Bob's your uncle.

If you intend overclocking the card, then I'd definitely advise using the fastest RAM you can find to avoid instability.

Bryce,

i have understand your first reply: we have in mind two different point of view!
Your reply is right, but the question was if it is possible to take advantage from the better performance of this memory chips.

That's what I was trying to correct in my last post (obviously unsuccessfully :D ). The answer to your question is then yes. Yes, it's possible to take advantage of their better performance by increasing the base frequency on the video card, but you'll still be limited by other parts, so you might not bring them to their limit if some other part can't go that high.

Do I need to change the card crystal or other hardware? Or do I just swap the ram and adjust the tool type?

Hello,

just to exchange the memory ICs of your Cybervision64 with faster ICs (all eight memory modules) and then make fine tuning with the software (the variable to set is MEMCLOCK).

Hello,

this part are correct for your Cybervision64, but pay attention at the max speed of this IC. I sell a 50ns memory IC: if you mix it with the 70ns memory IC of your Cybervision64, you dont have an increase of performance of your card. Only more memory for bigger video resolutions.
If it is OK, i will sell to you 4 parts.

But if you put eight of this parts on your card, you can increase the performance of your card.

Hello,

Yes, do you have further stock of these?... and do you find VRAM chips available to come by?

Cheers,

---------- Post added at 15:01 ---------- Previous post was at 14:59 ----------

Declaring interest.

I will take 10 DRAM's if you have them. I will PM.

---------- Post added at 15:04 ---------- Previous post was at 15:01 ----------

Willing to take less ofcourse depending on availability, and if other people are in need.

I could reduce the order to 6 if other people are in need.

I have a card that requires 4, but would like 2 spare... just in case.

Thanks
