Overlocking SATA?

[schoggi555]

this is a question that awnsers itself, but is SATA overklockable? Of all what i know: NO. If yes, then you will need an SSD. But imagine this was possile, what do you think must be done to achieve this? How far could it be overclocked? What would you do with it? Do they need watercooling then :P? I'm just wondering what you tink of it... I got on this idea watching slick's

I'm 99% sure you can't, only so much data goes through the cables right now. With data transfer they would make it as fast as possible without the need to overclock.

The only option right now to get better speeds would be to go for a PCI-E ssd. They get speeds upwards of 1000 MB/s through the PCI interface, as Sata 3 is now a bottleneck for ssd speeds.

Those are expensive as hell! I already saw those... I like them  :D

No you can't oc sata and also the technology isn't maxed out. Look at random read/writes and see how slow they are in terms of ssd speeds. They have another few years before things are maxed. Remember it takes 3 quarters to bring something to market after its invented. With that and also marketing bs, things are going slower then what they have to.

You could always set up RAID to increase bandwidth?

Search the forum for that answer as its here in a million spots and I have answered it myself a few times already

Bandwidth isn't the issue, because sequential performance isn't important.  Random performance is, and it's not using up all the bandwidth yet.  We need faster flash and better controllers to go with it.  SLC would be nice, but it's too expensive and has lower density.

Surely RAID 0 will double sequential r/w?

It does.  Now, name a situation where sequential speeds come into play.

Does everything not double? I was thinking of going RAID 0 for extra snappiness.

Yes it is possible to overclock your SATA ports. No idea why people say you can't. Ever since Sandy Bridge (for Intel), all north bridge tasks are based on a single clock, which is 100MHz at stock. This single clock controls the CPU, PCIe, memory and a few other things. When you increase this frequency, you overclock all of these things (including SATA). That's why it's a horrible idea to increase the base clock on newer Intel platforms by the way, because it will cause things like USB and SATA to fail, and your whole system becomes very unstable.

 

I highly doubt that you would see a storage performance increase by overclocking your SATA ports by the way, since you will most likely be limited by the controller and flash in everyday tasks. You might be able to see a very, very tiny increase (maybe like 1%, which is just margin of error anyway) in sequential read/writes if you got a top of the line SSD and run a synthetic benchmark though.

Arh. So it helps, but it doesn't double.
