I found an old post where a user was able to manually solder cache onto an OEM Intel NV430VX here: www.oocities.org/sjg/upgrade/cache.html
Besides the chips, he had to add several resistors as he documented here:
- R1E4 (22 ohm) -clock feed, series termination
C1E6 (4.7pf to 22pf) -EMI reducing capacitor
R2D1 (10k ohm) -provides Enable #2 (CE2)
R2F1 (220 ohm) -provides /Enable #3 (/CE3)
R4D4 (0 ohm) -provides /OE for Tag RAM
R4D5 (0 ohm) -provides 5v for Tag RAM (note: R4D1 is used if 3.3v Tag RAM is used)
C4D1 (.1uf) -decoupling/bypass capacitor
R3F2 (10k ohm) -MS to V+.
He said he was able to figure out all of this information by using these two guides:
Intel NV430VX Motherboard Technical Product Specification (August 1996) - www.elhvb.com/mobokive/archive/power_ut ... 182101.pdf
Intel 430VXPCIset Design Guide (June 1997) - ftp://ftp.efe.hu/doc/297469.pdf
I am looking to do the same with an OEM Intel 430TX. Using his post as a guide, what I can't figure out is how from just the two guides linked above, he was able to (A) determine resistor values, and (B) determine resistor location.
Can any of you make sense of this?
