Update IOS and requirements

[linuxtik]

I tell you, I have a router 2801 with the following features:
- 64M flash
- 128M DRAM

I want to update to IOS "c2801-spservicesk9-mz.151-4.M10.bin", But according to the download page the following is required:

- 64M flash
- 256M DRAM

Could I upgrade to this IOS version without having to update the DRAM?

what effects will it have on the stability of the system not follow the recommendations?

Regards. Thanks.

It won't work. The router won't be able to load the newer IOS.
