Any idea where I can find 512 KB cache for my i430TX based mobo

My P133 only has 256 KB of pipeline burst cache..and I was thinking it should help my SETI times some if I upgraded to 512 KB cache, and it should help my system speed too.

Are stores even selling this kind of cache anymore?
 
Wow, I just found this for $7. Any idea if it would work?

According to the Dell manual, my motherboard uses 256 KB of asynchronous SRAM, 256 KB of pipeline burst SRAM, or 512 KB of pipleline burst SRAM. Currently I have 256 KB of PB SRAM.

It doesn't list the number of pins or anything like that for the cache. Did all of the pipeline burst cache modules have the same number of pins?
 
Sukhoi- Do you have 256 KB on the board or in a coast slot? If you've already got 256 KB on the board then you'd want to pick up the 256 KB module listed HERE for your coast slot. I think the 512 KB module is for boards that didn't have ANY L2 cache on them to begin with.
 
The 256 KB cache I have now is on a separate card. I assume it's in a coast slot, but I dunno much about this kind of motherboard.

Do you think upgrading from 256 KB to 512 KB would help overall system performance enough that the user would notice it? After thinking about it, with the 3.0 clients out, the SETI times might not be affected much by the increase in cache. So for now, I'm just curious if Word, Excel, AOL, etc. would run any faster. Thanks!
 
From my experience upping the cache from 256KB to 512KB doesn't give a very noticable performance gain, but it usually doesn't hurt either. Is there any way you could o/c that 133? If your mobo supports a 75mhz FSB upping it to that would give you a P150. That would bring your SETI times down more than another 256KB of L2. You'd get a boost from the extra CPU clock speed and FSB speed. But I'd say since the 512KB module is only $7 plus S+H go for it!
 
Heck, if anything SETI would benefit from the added L2 cache. It would be interesting to see how much.

Cache has diminishing returns, and that is one reason why a CeleronA has only 128K of it. This was a significant improvement over the original Celeron with NO cache at all.

I would bet that your board does not have 75 FSB, but certainly would take a 166, 200 or even a 233. TXs support MMX, so I bet a 200 or 233MMX would drop in.
I haven't seen a 133 that would not do 166 at default voltage with a cooling fan though.

Doh, I might of got the board name wrong, but it doesn't really matter anyway. 🙂 After thinking about it, I'm pretty sure I have a i430FX board. I know it's the Triton chipset, and I think that's the 430FX, rather than 430TX. It's a socket 5 board, so I can't drop in anything faster than a classic P166. I can overclock the 133 to 166, but it's my mom's computer and she doesn't want to do that. The max FSB on the board is only 66 MHz, so no 75 x 2. 🙁

pandaflux, that should work, so thanks for the link. If my mom does decide to get the cache, I'll have to decide which of the companies to buy the cache from.

On Reseller Ratings CSO isn't rated to well. They seem to have bad shipping times, and sometimes you get used merchandise even if it's advertised as new. Computer Geeks is rated a little higher, but they also seem to have really slow shipping times, and I know for sure the cache from them is used.

There's a possibility a P200MMX OverDrive processor would work in the computer(I'd have to call Dell about it), but I haven't seen one of those things in years, so I haven't bothered to call yet. Last time I called Dell some idiot there told me I could use a standard ATX power supply in my 4 year old propiatary (sp?) AT case. Yeah right. 🙂
 
The extra cache will definately help SETI. Just out of curiosity, how long does it take you to complete a work unit?

 
Well, I have a socket 5 board which won't normally work with the P200MMX OverDrive, but there are a few socket 5 boards which will work, so I'll have to call Dell about it if I ever find the OverDrive processor anywhere to buy.

I get about 33 hours/WU with the 2.04 GUI on the P133. I'm going to put the 3.0 GUI on there real soon...maybe tonight. 🙂

I'm running the 2.70 GUI beta on this C433, and I get about 9 hours/WU.
