Hi, I'm in the market for my very first PC. I've saved and saved (for years) and watched the PC market as it has evolved and even better, as prices have fallen through the floor. As it will become apparent, I don't know a lot about what I'm buying, thus this posting. After lots of looking around and asking friends for recommendations, I have probably decided on a Gateway 2000 486DX2/66mHz ISA machine. Several trade journals recommend the DX2 machines and all suggest that a *minimum* CPU cache of 128K is the way to go. Unfortunately, Gateway only offers 64K cache. Their sales representative suggests that I could get the cache increased but they do not currently do it. They even gave me the number of a guy who sells cache memory! I called him and he said that all I need to do was to pull 8 chips out and insert his 8 chips and cache would go from 64K to 256K! And all for $69.00 for the set of 8 chips! Now this sounds too good to be true! Is this kosher? He did mention that a jumper would have to be changed and the books that come with the PC should show me how to do this. Is this standard or is there a possibility that the Gateway system doesn't have the sockets for the new (and larger) chips? EVERYTHING else in the lineup of features meets or exceeds my personal requirements for my new PC with the exception of the cache memory. Anybody done this, with success. Obviously no one has the system described above cause Gateway hasn't shipped the first one yet. They say in about 6 weeks. Still, if anyone can shed some light in this area, I would be most appreciative. I tried calling Gateway back but unfortunately they require that I speak with *my* sales rep who has gone for the holiday weekend. =-( Guess they are making money faster than they care for.... You can reply directly back to me, or post, either way is greatly appreciated. -- ----------------------------------------------------------------------------- Gantt Edmiston - SysAdmin |If you always do what you have always done, SAS Institute Inc. |you'll always get what you've always gotten!

Gantt,
I(we) have a Gateway 2000 486DX2/50 EISA (not ISA and not 66mHz) but it comes
with 128KB direct mapped cashe. The manual shows how it can be easily
upgraded to a 256KB two-way set associative cache system. On my system board
you need the following:
One 128K SRAM SIMM module
Two tag SRAMs (28 ppin DIP IC)
One LRU SRAM (28 ppin DIP IC)
no setting of switches and/or jumpers.
Again, this is for the Gateway 2000 486DX2/50 EISA using Intel's 82350
EISA chipset.
I suggest if you're gonna do something like that, wait til *your* sales
rep returns after the holiday.
Hope this helps.

Unfortunately, Gateway >only offers 64K cache. Their sales representative suggests that I could (deleted stuff..) I have a GW486/33E. In the manual, it gives detailed instructions on how to upgrade the cache, including exact part numbers and the like. However, it also states that ugrading the cache will provide little, if any (and it makes a big point of this) difference. I figure GW2K is doing one of two things: 1) they are telling us the truth, or 2) they discovered that the motherboard doesn't like the expanded cache very much, and decided to lie to us. I'll stick with the first. My system is so fast it's mind-boggling. Well, not quite. I'm saving up for the DX2 to stuff in it.. <Grin> -Dave -- ----------------------------------------------------------------------------- Kappa Xi Kappa - Over & Above! dcg5662@hertz.njit.edu 9 Sussex Ave., Newark, NJ (car theft capital USA) 70721.2222@compuserve.com
