Apple have some of the longest lasting PC’s on the market, the only downside is, after several operating system and program updates, your old Mac may feel slow. It’s also possible, for power users, that the stock RAM install just isn’t enough. Either way, we can get you the upgrades you need and get you up to the level of performance you’re craving.

We can't find products matching the selection.

RAM is specific to each machine, so we’ve helpfully listed just what each upgrade is compatible with which machine, but if you need help or advice, please get in touch with us by phone, email or contact your nearest high street KRCS store.

We offer free shipping and if your order item is in stock and the order is placed before 2pm, we’ll usually ship it the same day. If you need your RAM sooner, or require it fitting you can use our free click and reserve option to contact our friendly local high street KRCS stores.
