Pushing the boundaries of the ICH10R

[jhbodle]

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?

[Spoiler]

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?

Why do you care? The extra 70mb/s large file sequential reads will not do anything for you.

Lol I know, but like everyone who visits this forum, if there's any way of getting more performance out of my system I want to try it! This is Xtreme Systems after all :-)

lol dont be offput by one hertz. he is always grumpy. being wrong all the time does that to a guy
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!

If you plan on increasing your SB voltages, you might want to consider getting everything else off there. I.E. your sound card.

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

ICH10R is a great controller - only shortcoming is max seq read/write falls short compared to what the best h/w controllers can do - max is something shy of 700MB/s or so.

And what the hell is raising the ICH voltage gonna do for him?
Except for a hotter SB I mean
That's right, nothing at all.

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

[jcool]

NP, it's gonna be mine too

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 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.
