I understand the concept behind the Mhz speed of RAM. But would you go for 128Mb of 133Mhz or 256Mb of 100Mhz. I believe that it would be wiser in the long run to set up a computer with a 133Mhz FSB not 100Mhz as upgrading is not that hard. Save up another $150 and get yourself another 128Mb DIMM and you have to 256.. right? are you following? opinions.
 
Sure, get the 133MHz, it's not much more $ at the moment. I really don't think it's gonna make much difference - from an upgrade perspective. If for instance, your building a system based of the BX chipset, which is 100MHz FSB - buying 133MHz, well sure why not, it's only about $5 more per 64MB. But, by the time you do upgrade, the 133MHz ram will have been replaced by something new, DDR or something. 66MHz bus is still pretty common, and quite capable. Performance increase between 66 and 100, not that big a deal, 66 and 133, maybe a bit but not ground breaking.

133 FSB is a scam. Intels botched chipset supports 133MHz, I suppose the Athlons will run at 133 overclocked... (200MHz FSB crap - maybe someday, but not at the moment). If you want 133MHz the only real chipset choice is the VIA, but then your risking potential problems that non-intel chipsets are famous for. Stuck in 100MHz for the moment, these are trying times.

Personally, I would like to see the software end of things improve. We have the horsepower at the moment, but bloated applications and OS's (including W2K, the most bloated of them all as far as install size). I know they can do better (programmers), but we are a small crowd.

I got an option for ya. I have a P-III coppermine .18 micron slot 1 chip for sale for $ 250 or a Celly 400MHZ and Mother board I would sell for $ 150.00
 
A few weeks ago I bought an ASUS P3V4X motherboard that uses the VIA chipset with 133 bus speed. Right now I am using a Celeron 333 (66 bus speed) with 100mhtz RAM, using Cakewalk 9 and a Gadget labs 8 channel hard disk unit. Everything seems to be working fine. I intend to upgrade shortly to a P3-600E chip (133 bus supported) or faster, and when I do I will swap out the RAM also. If I had not already owned the RAM chips I would have bought 133, and I agree that for the price difference it is what you should buy regardless. The more RAM the better - there is no other single componant that makes such a huge difference in performance.
 
If Im running a BX chipset at 100 Mhz FSB then can I use pc133 RAM? Can I use pc100 RAM side by side with pc133 RAM? What's the difference?
 
bobolocks:

You can use 133MHz ram in your machine sure. Side by side with 100MHz DIMMS, probably, but potential problems.

The diff is technical, higher MHz for higher FSB's.
 
RWhite: I'm running a celeron 333 also, but I went into the BIOS and overclocked it to 416. A computer tech told me any faster and I might encounter problems. After a year running at 416, I've had no problems. You might want to try it.
 
I see a lot of folks that hang out on these boards don't follow the articles at Tom's Hardware...the Intel BX chipset is perfectly capable of 100mhz+ FBS speeds...Intel just doesn't want you to know it...all you need is a motherboard that allows you to push the envelope.
I'm using an ASUS CUBX board...officially this board supports 100mhz FSB coppermine core FC-PGA Pentium IIIs and Celerons, or 66mhz FSB mendocino core PPGA Celerons...unofficially the board will support FSB speeds of up to 150mhz, and will support any speed FC-PPGA Pentium III to date, including the 133 FSB variety...133 FSB is no big deal, for this board...and it does it all with an Intel BX chipset!
 
The long term goal for the manufacturers of RAM is to phase out 100Mhz. 133Mhz chips will work with 100Mhz. On a 100Mhz board, the 133Mhz chip will only run at 100Mhz. Just meaning that you aren't using the chip to the fullest potential.

Crucial Technologies (Micron's name for their own factory distributorship ) sells same-sized PC100 and PC133 DIMMs for the exact same price...their prices are reasonable, considering it is lifetime memory. You can order direct from them at their website: crucial.com
 
reading up lately

ive been reading up a lot lately checking out what im going to do with buying a new computer and i learned that the reason you want the fastest ram is because if you overclock a 100FSB chip and motherboard with 100Mhz ram you can rn into troubles. If you have a 100Mhz board with 133Mhz ram you can have a lot more (since this is a recording bbs) "headroom" for overclocking. but since im getting a P3-733 and PC133 Ram, if i overclock from the start then it would be harder then getting a P3-700 running at 100FSB, with PC133 ram. Since the 700 is locked at a 7x multiplier and the 733 is locked at a 5.5x mulitplier making the 700 more bang for each overclocked Mhz on the bus speed.
