TRIM under XP

[idata]

Hello,

I have bought a X25-V and i'm under XP, how to activate TRIM ?

what is his advantage ? i know TRIM is used by defaut on Windows7....

labtec, I may have found an AMD TRIM-supporting driver for you, I started a new thread in the SSD discussion group about it, but here is the link to that information:

I believe my performance improvement while running through sata III was due more to fact of having to run in ide mode on the sata II ports due to the AMD ahci driver being corrupted or not loading correctly as opposed to the extra bandwidth of sata III.

My drive wouldn't boot on my sata II ports when set to ahci in the bios even though the AMD ahci driver was loaded at f6. When I boot through sata II with ide enabled I can boot and trim but extremely slow. I am able to boot from my sata III ports through the Marvell controller with ahci enabled in bios for ports 6&7, sata III, and it flies but with no trim support.

I had been keeping benchmarks from both ports but I saved them on the boot drive that I secure erased last night. I'm reloading XP for another try and I'll record my results.

As far as the msahci driver is concerned I thought I had read on one of the ssd forums that the msahci driver from Vista 32 would work on XP 32 enabling trim support. I haven't been able to test it because I don't have a copy of Vista on hand and I can't seem to locate this file online.

Thanks for the Marvell link. I havent tried it yet but looking at the driver name "Marvell_SATA3_Win7_64(1.0.0.1051-WHQL).zip" it seems to be a Win 7, 64 bit

driver but I'll try it. The AMD driver is only for Win 7. and can be downloaded separately from the CCC driver package. I'm starting to think the only hope for

XP, AMD and SSD's is some sort of trim capabilitys built into the bios of the controller chip on the ssd. I'm going to keep searching for another way, I can't be the only one using this combination without success. Thanks for your help.

labtec, I see what you mean about the Win 7 thing, I wasn't recalling your setup at the time. Also, I've read that Vista does not have TRIM support even if the driver is "msahci", only WIn 7. So yes, you may be out of luck with all this. I run the Toolbox on Vista just fine, FYI.

I understand your results with your SSD now, thanks. One test I saw, albeit with Intel or MS drivers, did not show a huge difference between IDE and AHCI mode, but I don't doubt what you said. I read that the AMD SB850 chipset supports SATA 3, here is an article about that:

http://www.bit-tech.net/hardware/storage/2010/10/28/are-on-board-sata-6gbps-ports-fast-enough/1 http://www.bit-tech.net/hardware/storage/2010/10/28/are-on-board-sata-6gbps-ports-fast-enough/1

So you'd need to get the Win 7 msahci driver and hope it works in XP, on the AMD chip, who knows if that would work.

Something else, the Intel Toolbox needs .NET Framework 2.0 to function, which is not part of XP (see the Toolbox User Guide.)

You could have a TRIM'd SSD with the Toolbox if you can get it to run on XP. Is the Toolbox on XP impossible?

parsec, I know I won't have automatic trim support no matter what I do, I'm just tring to get the manual trim through the toolbox to work.

I think my next step will be to upgrade to seven or replace my motherboard and AMD cpu with an intel i7 setup and sell the new

AMD/Gigabyte on flebay. This system was new in November and hasen't worked yet. Should have bought Intel !!!
