Hi all,

Basically the last few bits of my new build arrived this morning, first here's a run down of my setup:

mobo: MSI GD-80 P55
cpu: Core I5 760
ram: OCZ Reaper 1600mhz
GFX: Powercolour 4890
PSU: OCZ modxstream 600w
SSD: Crucial C300 128GB
Controller Card: Highpoint rocket620
Sound Card: ASUS Xonar DG

I installed everything, plugged the rocket into my PCI-E x1 slot above my gfx card and installed w7 onto the ssd.

I decided to run Crystal mark to test my ssd's speeds and there was a problem - my reads weren't breaking 200 (don't get me wrong, I know that's a great speed) But seeing as It's running on a sata3 card I was expecting 300+.

Under device manager it's showing "marvell 91xx config ata device" with no drivers installed - nothing on windows update and the drivers from the rocket site don't do anything.

Just out of curiosity I plugged the rocket into my spare PCI-E X16 slot and that seemed to fix it, I'm getting 350 odd read speeds (drivers still not working though)

Is this some chipset limitation that I am unaware of on the P55? If I leave my rocket plugged into my Second x16 slot I'm pretty sure that's going to bump my first one (where my 4890 is) down to x8?

To be honest I'm a bit confused

I guess the driver issue could be because I'm running W7 64-bit...

I've plugged the Drive into my motherboards onboard sata port for the moment untill I can figure this out.

Sorry it's such a long post, any help or idea's would be much appreciated :(

Thanks
 
yeah came with driver CD, they don't work though :(

regarding the x1 slot, I've just read my mobo manual and realised the bottom slot supports x4 -going to swap some bits around and see how it looks.

Think it was just me rushing into 'worst case scenario' mode without going through anything methodically... Will report back.
 
I have the same controller and ssd. From the initial install I did it was running the standard Microsoft drivers as from what I could tell if you install the Marvell ones then TRIM doesn't work. I am not sure how true this is as I haven't used it for long enough yet as I have had to swap out the mobo recently and haven't finished rebuilding the pc yet.
 
Mr Paul may well be right despite the card advertised as a 1x board. There are quite a few people not getting 350Mb/sec unless it's in a 16x slot.

Just saw on Highpoints website that the card is PCI-E x 1 compatible but only supports sata I and II (up to 300mb/s) in a x1 slot.

Great mis marketing if you ask me.

It's not actually Highpoints fault - It's an Intel chipset issue, they only actually support PCI 2.0 (i.e up to 500MB/s over 1 lane) on the graphics ports that connect directly back to the cpu/northbridge. The other PCI-E lanes which are connected to the southbridge claim to support PCI-E 2.0, but are speed limited to the 1.1 spec speeds of 250MB/s per lane. When overhead is factored in this is why you are seeing such disappointing speeds.

AMD's chipsets properly support PCI-E 2.0 on all the lanes they claim to, so you could get full speed there.

This article should tell you everything you need to know - http://www.anandtech.com/show/2973/6gbps-sata-performance-amd-890gx-vs-intel-x58-p55/2

Cheers for the replies guys.

bit of a PITA really, I should have done a bit more research before I jumped in and brought the card.

I might just try and ship the mobo off on mm and grab one with sata3 support onboard.
Trouble is my mobo just looks so damned pretty :rolleyes:

You could try swapping your Highpoint card for one of the Asus ones. The Asus has a x4 connector, and you mentioned a free x4 slot.
Even at PCI 1.1 speeds, a x4 slot provides 1GB/s bandwidth, which should be enough.
