I have 3 Intel X25-E 32GB SSDs in RAID0 on the onboard ICH10R controller on my motherboard and the SSDs are fast enough to hit the throughput limit of the ICH10R (667mb/sec). I have tested this with HDTach and ATTO - both top out at roughly 667mb/sec.
Could I get more throughput from the controller by increasing the PCI-E bus frequency? Has anyone tried this on an ICH10R? And as i'm worried about damaging components, is 105MHz a safe starting point or is the bus too sensitive for any tweaking?
The ich10R is not run on on a PCIe lane. For a P45 motherboard, the ich10R is a southbridge chip that has a 10 Gigabit (Max 1.25 Gigabytes) DMI link to the northbridge. Raising any of your PCIe lanes shouldn't increase your controller performance.
Ah, OK thanks for that. Is there a way to perhaps increase the frequency of the DMI link or some other way to increase the throughput?Quote:

every single mb/s is important. trying upping your voltages on the respective controller on your motherboard, and see what that gives ya!
Thanks, will give it a try!Quote:

MOAR MEGAHURTZ AND MOAR VOLTAGES!
just dont get too crazy... considering you've dropped the coin for 3 of those drives in raid im assuming you have a few extra bucks for an add in controller... id just buy a card instead of possibly frying your sb
Well when I originally got into the whole SSD thing I bought an Adaptec 5805 RAID card but it wouldn't initialize the card's BIOS on my PC. I put the SSDs on the ICH10R and to be honest I think it's an underrated controller now - very quick disk initialization time and it seems as solid as they come. A proper RAID controller would probably work now i've changed motherboards, but i'm happy with the ICH10R for now...that is, as long as I don't watch that YouTube vid of the 24 Samsung SSDs in RAID giving 2GB/sec throughput :DQuote:

And what the hell is raising the ICH voltage gonna do for him?Quote:

That's right, nothing at all. :shakes:
If you want MOAR sequential throughput, get a controller (and more disks ^^)
I'd recommend the LSI 9211, as it is VERY affordable, adds almost no latency and can handle 1,5GB/s+ easily.
Thanks for that, it's going to be my next purchase :DQuote:

you must not be very familiar with raid and ich10r mr jcool. maybe if you put a few devices on a ich10r you will see what i am referring to. it is done very commonly, and not only do you get a hotter chip, but you also get a faster system :p: if he isnt cooling his bridge effectively i hope he isnt going to try it, but this is an overclocking forum, and i am sure that he has at least an idea of what he is doing.Quote:
