-- How much RAM do you have???
Pages (3): « 1 2 [3]

768mb ddr ram on my 2ghz p4 laptop. It's the bus that's slowing me down atm, and maybe the cpu a little. I don't think I'll need more than 768mb, but I'm gonna buy a new pc soon, and I'll prolly going to ask for 1024mb ram.

I was messing with you guys i photoshopped that shizzat and waited for a reply lmao.


its actually 2.61ghz and 1gb of ram

Does it actually matter if you have 1024 mb spread over 2 x 512 mb? Does 2x512 work faster or slower or the same?

actually its better to have a gig in 2x 512's cause if one gets screwed you still have the other 512... but i think its actually faster since they both have seperate processing or whatever

Well let me know how it goes. I simply don't understand how the OS or any of the apps would even realize that it is a dual-core CPU, let alone know be able to make use of it. It uses the same socket and everything, so it seems to me that it would just "look" like a regular single processor at the software level.

If you're using dual-channel memory (and almost all new computers do) then the performance benefit from getting separate sticks is negligible. And it also limits the potential to upgrade because you've got a limited number of slots.

Dual processing sounds so easy on paper that you'd think it'd be so easy in reality but it's impossible for two CPU's or a dual core one to do the same processing task at the same time unless the app is designed for it.... otherwise there could be redundancies etc

Dual cores can't process the same task at the same time so it's only useful in sharing various tasks. ...

It's very tricky.

Yes, we learned all this in electrical & computer engineering. Caching and shared memory are the biggest problems.

It is never possible for two processors to cooperate on a single task, whether the app is designed for it or not. Dual processors are only good for multitasking environments - that is why they're commonly used in servers, which have to do several different tasks for several different clients simultaneously.

This is why I question the dual-core architecture; if the application or OS isn't aware that another "core" is available, how is it able to delegate tasks and threads to one "processor" or the other? Only the OS and the application have any understanding of which tasks can actually be performed at the same time - the hardware has no knowledge of this.

So will there be special motherboards, designed to make these CPUs look like two separate processors, sort of like the Intel boards do for the HyperThreading chips? Or do the CPUs just take a wild guess at how the workload should be divided and potentially hurt performance if they guess wrong?

As you say - it's tricky, and I'm going to wait to see real-world figures before investing in one of these dual core CPUs. AMD has a good track record though - I'm sure there must be some logic behind all this.

512 DDR 266 xD
