How much memory I loaded up some software back when. Then earlier this month loaded on an update. (Was that ever a mistake) The manufacturer now mentions, I need a bunch of memory (RAM) loaded on too if it is to continue running in Win. 98. It is flat taking much too long to process the files I now find. Per their consultant can take up to 100x longer, without sufficient RAM, for it works the hard drive (which I can see it does). I perhaps ought to add more. What I got is an older H-P Pavilion, a model 6563Z . The type with a cheap 500 mhz processor. It currently has 128 meg of RAM on board. I'd like to get more going on it. Essentially as much as possible. The motherboard has two slots for 168 pin DIMM. It also has a bracket that runs along the edge of the memory boards, so cannot get too over done with size vertically, for may not fit. Will this motherboard support more RAM? Will it support 256 or possibly 512 meg? I see single sticks of 256 meg, 168 pin DIMMs on occasion. Do you foresee a problem here? Wm.

From Google it seems it can support up to 256M http://www.edgetechcorp.com/memory/... [W98 is OK up to 512M without tweaks so the operating system is not a problem]. What is the software that requires the RAM increase and can you not simply uninstall the update? DerekW

Oh, many years ago, had been told that certain motherboards would not support big memory. Thus wanted to check here. The software Mfr. is in the U.K. and it is a CAD conversion program. They reccomend about 512 meg (or better). I thought there to be a hang up with many motherboards not able to handle greater than 256. A few topped out at 384. Aw, nuts. I think I can borrow two 128 DIMMs from neighbor to see how they work. Problem being is due to arrangements inside the case, it will take 20 minutes to get in there and be able to pop them out. Wm.

The max your system can handle is 256MB. I assume 128MB per slot, but it doesn't specifically state that. Regardless, you have one 128MB already, just add another & you're done. http://www.crucial.com/store/listpa...

jam My link in #1 kinda "recommends" the RAM sticks being equally sized, so it does seem that another 128M is the neatest way forward (if the CAD update can't be uninstalled). DerekW

I actually have two of the 64 meg DIMMs in place. Total of 128 then. When neighbor gets home, should be able to borrow for a while two 128's. The updated software is already loaded on. And, can't be removed. Per their rep,. it works OK as long as the overall drawing size is small. 99% of their customers must do such. I, however work with ten feet long drawings. Which is when the rep, said to up the memory. Absolutely zero is mentioned else where, that an upgrade to memory is required. "Oh, didn't anyone tell you?" In asking to go back to what was when, according to them Nope. Can't be done for it alters your registry. Bleeping out anything will remove the elements, plus take elements shared with other softwares. I didn't write it, I only use it. Wm.

... just thinking aloud: If you still have the CD or original download then I guess you could uninstall the lot, reload the original version, then set it up as before. DerekW
