MEMORY UPGRADE

Hi there

Can you plese tell me what type of memory will be compatible with my computer. Is is quite old probably 5 years old.  It has a pentium II processor 233 MHZ.  not to sure if you require any more details.  Want to upgrade it with at least 256RAM.

Thanks

This type of computer probably takes standard SDRAM, as opposed to the newer DDR-SDRAM.  The bus speed is 66Mhz, but unless the BIOS is picky you can safely install the newer 100 and 133Mhz rated memory.  Some BIOSes will complain about mismatched speeds even though there is no technical reason faster rated memory can be used.

There is a small chance that this computer needs the even older EDO type memory.

Do you know the brand and model number of the computer or the motherboard?  For example, "HP Pavillion 5000" or "Asus KT6"?

You can purchase standard SDRAM from www.crucial.com which is the retail outlet for Micron, a large manufacturer.  Simply select standard SDRAM in 100 or 133Mhz according to your budget.  Avoid the temptation to get extremely large modules, like 512MB, because of technical issues with newer modules and older motherboards.

All I know is the computer is pf Phillips make.  Do you know how I can find out what brand and model my motherhoard is?

Thanks

You should be able to find out the model no. of your m/b from the m/b itself. Often the info is printed on the m/b.

I think it will be well worth your efforts to establish the exact model no. as it is highly likely that your board will only support older type EDO RAM. By the way not long ago many m/b suppliers claimed their m/b could handle 128 of RAM when in fact they could not. I have one such m/b and since I have drive overlay software and many partitions (not thru choice) I decided it wasn't worth the hassle getting my machine to recognise the installed 128 of RAM - instead I put up with it only recognising 64 - as the chips came out of an obsolete I'm not too bothered. But don't assume that even if you get the right RAM that it will necessarily work on a realtively old m/c.

Hope that helps

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

download free tool at belarc.com this simple tool will tell you alot about your computer, from type of motherboard, bios and the drivers that are on it . There is another tool called aida32 http://www.aida32.hu/aida32.php that can even give you more info on your system

I tried to search on the Philips website but they don't have a comprehensive list.  I need an exact model number.  There should be a sticker somewhere with a model number.  It might be on the back, expecially near the power supply.  Philips makes a lot of parts like monitors and cdrom drives, but I can't find any mention that they make the whole thing.

We can either fiddle around with trying to figure out the model or we can examine the memory that is already there.  Turn off the computer, open the case, and remove one of the memory modules by pressing down and out on the little clips at the ends.  If the module is 5 & 1/4 inches (13 & 1/3) in length then it is SDRAM and get it here:
http://www.crucial.com/store/listModule.asp?module=SDRAM%2C+66MHz&cat=RAM&package=168-pin+DIMM&submit=Go
Get any of the three 'non-parity' modules.  Count how many slots are in the computer and multiply by 128 for the maximum.  Crucial should be taking into account density issues that patricab has mentioned so you can almost certainly use the 128MB modules.

If it is shorter than that then it must be EDO type, sorry no EDO handy to measure but it is not nearly as long as SDRAM.  In that case, you can get it here:
http://www.crucial.com/store/listModule.asp?module=EDO&cat=RAM&package=72-pin+SIMM&submit=Go
Get any of them up to as many slots in the computer according to desired total capacity.

Oops, forgot to label the 13 & 1/3 measurement as mm.

It appears that you have 72 pin memory modules. Those memory types are harder to find and generally more expensive. contact the guys at www.bkcomputing.com for memory strips.

Very few PII boards came with slots for 72 pin simms.  Even if he doesn't know the model he can look at the memory slots and tell us what color they are.  If they are long and blackish-grayish then they are standard sdram pc100.  If they are shorter and white/off-white then they are 72 pin simms.  Every PII board that I have ever seen with support for 72pin simms also came with slots for sdram.

In any case, he can probably take, at least, 128mb dimm (sdram pc100).  Since it is a PII he won't require pc133.

If, on the extreme rare chance, he requires simms it is unlikely he will be able to add 256mb of ram (total).
