ich5 vs ich5r

[crispy2010]

I have a p4c8oo deluxe and a abit ai7. The ai7 has the ich5r southbridge, is this a better raid solution compared to the p4c800 deluxe which has the ich5?

I am running 2x 36 raptors in raid 0. On my k8n neo platinum hdtach gave me burst at 199, on the p4c800 in raid0 (on the promis ft 378) I am gettung burst 116. Will the ich5r get me back to burst speeds around 199?

Thanx chris

Will the ich5r get me back to burst speeds around 199?

Most likely it would, since the ICH5R is native southbridge-based and not stuck on your PCI bus (which is where you're running into that 116MB/sec wall).

Bigger picture: do you need that much straight-line burst speed for any actual purpose, or are you just addicted to HDTach for its own sake? one real-world result using ICH5R and dual 74GB, single 74GB and single 36GB Raptors on an ICH5R. Note that the RAID0 array isn't the fastest game-loader in that test, either... single was faster.

Anyway, hope that helps some.

Yes I am just addicted to the benchys, !


I can tell a diff between the ide and the sata raid, plus I need the76 gig os space, two36 just dont cut it!


I thank you for the link, and the opinion!

Yeah, then it is probably going to be worth swapping boards for you If you're not already aware, there's quite a batch of BIOS settings that inter-relate on the Abit to make it do what you want. Or don't want, more likely. So here is something I cut & pasted just to help you be aware of all the places where you may need to make choices in the BIOS:

but where i think the main problem was - was in the bios settings - here are the settings that worked for me (this one is without raid - im waiting on a second disk to set up the raid):

note - these are from memory (and from your other thread) - i dont have the box in front of me atm:

Under Integrated Peripherals -> OnChip IDE Device:
IDE Bus Master - Enabled
OnChip Serial ATA - enhanced
OnChip Serial ATA Mode - ide
SATA RAID ROM - Enabled

Advanced BIOS Features:
Hard Disk Boot Priority - 1. Bootable Add-in Device
Bootable Add-in Device - Onboard sata
Boot Other Device - Enabled

I'm not saying you want all those set this way yourself, since you're doing RAID0 instead of single-drive, but knowing what settings it's looking to have tweaked may be helpful.

raid 0 suxs
dont put them on raid 0 and have to 36gb

Just having them togather as 74 gig is worth raid0, The speed doesnt hurt!

This may be true, although I just noticed, the games install about twice as fast on the raid!
