Hi, I have 128Mg ram and want to install more. The chipset has 8+8 (doublesided) modules. and is PC100. My system is PentiumIII, the motherboard has a paper label stuck on it wich reads SL-67EV1 (Solteck). But electronic check (Belarc Advisor) returns following: System model VIA Technologies, Inc. VT82C692BX. Motherboard model 693-596-W977. Question one: Shouln't I use one-sided ram chipset? Question two: can I use PC133 Ram (my Bus Clock is 100 Mgz) Many thanks! Carvalho

Well, You will gain nothing by installing 133MHz sticks on a 100MHz bus!!! You may have problems mixing RAM stick types with the existing RAM(maybe not?) Always a good idea to go to www.crucial.com to input your computer model (or mobo model if tech built). It will tell you exactly what your mobo can take, even if you buy elsewhere. Good luck!

Thanks a lot for the tip. Well, I was wondering if I could install a 133mhz stick because, the stores I visited sell it much cheaper than the 100mhz ones...! Again, could anyone tell me if one-sided (high density)ram chipsets will perform well with my motherboard (specifications in 1st message) Thanks! Cheers, Carvalho

I would guess that high density RAM will NOT work on your board. One way of telling is to divide your total RAM capacity (found in your manual or the mobo manufacturer's website) by the number of DIMM slots...if your board can't handle 512mb/slot, it won't accept high density RAM sticks...either it won't be recognized at all, or it will only be seen as 1/2 it's rated capacity (i.e. 128mb seen as 64, or 256mb seen as 128). Doesn't matter if it's PC100 or PC133, it has to be the proper density. http://howto.lycos.com/lycos/step/1,,5+30+82+23519+37366,00.html

Many thanks, jam and DublA! My main problem is to find out the specifications of my comput. Maybe you can help me. I got these results from a scanning software: Motherboard name: Soltek SL-67EV(1) (2 ISA, 5 PCI, 1 AGP, 3 DIMM) Motherboard Chipset: VIA VT82C693A Apollo Pro133 System Memory: 256 MB (SDRAM) DIM: System: VIA Technologies, Inc. VT82C692BX Before reading your posts, I installed a stick of high density ram memory (128MG)along side with the other one (low density). There's a small improvemnt of performance, but very small. I would change it if it could be improved. The fact that the system scanning software recognizes the 256MG means anything good or the system may not be using them all? In the Crucial Memory site, the automatic system to determine my needed memory asks my computer's manufacturer. Should I say Solteck or Via? Finally, jam, if my motherboard is Solteck I read in their website: Main memory: from 8 MB up to 768MG SDRaM with DRAM table free configuration; with 3 slots, this means (256) high density not supported? Is this right? Many, many thanks! Carvalho

Hi jam, for the sake of clarity: In the last part of my previous post, what I read in the solteck website goes from "Main MemorY".... to.... "configuration". The rest of the post is my question... Cheers! carvalho

If your total main memory is 768mb & you have 3 slots, your max per slot would be 256mb (768/3)....that means that high density RAM is NOT supported. This site gives a quick explanation...look at the table labelled "High density vs Low density": http://home.cfl.rr.com/bjp/Sdram.htm If you have 2 sticks of 128mb RAM installed & they're both being fully recognized, neither of them is high density. Single sided or double sided isn't always the best way to tell if the RAM stick is high or low density. If you go to the "how to" site I posted in response # 3, it will explain exactly how to determine what you have.
