32K*8 12ns cache SRAM for 386, 486, Pentium machines.
Brand new, direct from IDT's factory. Beware of fake SRAM on eBay/Ali.
I have a few other types of SRAM, and can make up a kit for your 486 if needed. See my other products, such as 64Kx8 and 128Kx8.
Check your motherboard manual or TotalHardware99 for the required cache ICs and jumper settings. It is not always obvious what chips and how many you require. Sometimes you need 5 or 9 chips.
This listing is for a single 32K*8 chip.

eBay doesn't allow custom shipping service names.
"Economy" will be tracked airmail to most countries, but untracked to a few more remote ones. 1-2 weeks usually, but can take longer.
"Expedited" will be DHL Express. 3-4 days usually. Exact quotes vary depending on the country. I can refund if you are overcharged.
