TRIM/AHCI support on AMD/nVidia chipsets

coolVariable, From the third link in your "let me Google that for you:" http://techreport.com/discussions.x/18653 So Intel's supposed support for TRIM in RAID mode is mainly marketing spin, as there is no real benefit to running a drive in RAID mode unless it's actually part of an...

TRIM/AHCI support on AMD/nVidia chipsets

coolVariable, the AMD SB710, a pretty old chipset, supports true AHCI, TRIM and NCQ while using the MS drivers. Not sure what you mean by "full speed." Obviously not all SATA chipsets will perform identically in all usage patterns. The Intel SATA controllers might slightly outperform the AMD...

TRIM/AHCI support on AMD/nVidia chipsets

Good info, thanks for all the responses. I think I'm going to go with an AMD-based motherboard (probably SB710) because: It supports true AHCI The MS AHCI driver will support TRIM and NCQ and will perform as well as or better than the AMD driver, whereas with the nVidia chipsets you...

TRIM/AHCI support on AMD/nVidia chipsets

Thanks for the info about AMD chipsets! I'm building a budget gaming rig soon based around a Phenom II X2 3.1 GHz and I had been considering an nVidia MCP61P-based board, but after reading some comments, including yours, I am now leaning toward an AMD SB710-based board like this...

TRIM/AHCI support on AMD/nVidia chipsets

Couple questions: 1. Is the consensus that to get proper Windows 7 TRIM support on AMD/nVidia chipset-based motherboards, you need to use the standard Microsoft PCI Standard Dual IDE Controller driver (i.e. either MSAHCI.SYS or PCIIDE.SYS)? These threads seem to indicate, yes...

SSD Controller is aware of OS partitions?

Maybe that explains it. It sounds like they're saying that the Intel controller allows you to manually set the free space through some proprietary API. But it does not say that simply making a smaller partition in Windows accomplishes this. Maybe this special ability of Intel controllers is...

SSD Controller is aware of OS partitions?

Granted, the SSD is aware of its internally-allocated free space. E.g. an SSD with an advertised 80G capacity might have 5~10G internal free space in addition to the 80G of virtual LBA's that it exposes to the ATA host. But if you made a 75G partition, the SSD would have no way of knowing that...

SSD Controller is aware of OS partitions?

Hacp, how exactly would the SSD directly recognize the free space when you partition a drive in Windows to less than its full reported space? An ATA device like an SSD or conventional HD doesn't know what a partition is -- that's just a logical construct, defined by data stored in an LBA...

SSD Controller is aware of OS partitions?

I'm just getting back to this thread. Thanks for your thoughts. It sounds like, as I suspected, the spare space gained by using a smaller partition isn't recognized directly by the SSD. I guess what Anand was saying is that leaving some space unpartitioned just gives the SSD more breathing...

Why do sites not review minimum frame rates? Isn't minimum frame rates the most important? I know they review average.

Cendyne 32x12x40x driver needed!

ashsia's right, you don't need drivers for your OS to recognize a CD, DVD, or CDRW drive. Sometimes the CD recording software will not support a newer or more obscure burner, and in that case you need an update to the recording software. Modus

Modem Drivers for ME, cant find them anywhere

Well it's definitely not a driver issue, because those are the genuine drivers for that card/chipset. Plus, it works when you install it on the Win2K machine. So it's probably an IRQ conflict like you said or, more likely IMO, some kind of Windows Registry/INF glitch. << Weve found out that...

There are essentially only two kinds of PCI modem chipsets made by Conexant in recent years: HSF and HCF. Both are "soft" modems, the difference being the HCF style does has a hardware controller (kind of like the venerable Lucent LT), while the HSF handles both control and signal processing in...

AnandTech's server benchmarks use an actual script taken from a typical "day in the life" of the web, database, and forum servers. This script is replayed against an old database using the hardware in question. Such a method is about as real-world as you can get, and highly relevant. Now why...

Yeah, when you pull on the Sysmark thread, it starts to unravel in a pretty ugly way. Funny that it needed to be "registry patched" to enable SSE support on the Palomino, when the software ought to detect such instructions independent of the CPU make or model. Funny too that Intel chips have...

It's always wise to keep the pool of benchmarks fresh with new tests. Otherwise, manufacturers tend to optimize their hardware for particular tests rather than general usage. And the larger benchmark houses like Bapco and Ziff-Davis can grow arrogant when their tests become the de facto...

Bleep is right. And for old times' sake. . . There are a number of reasons to avoid higher priced "hard modems," especially those made by 3Com/USR, in favor of a common PCI winmodem. 1) Winmodems are dirt cheap. While a good Lucent LT or Rockwell/Conexant HCF winmodem can easily be found...

The choice between RDRAM and DDR only applies to P4 systems; Athlon-based systems don't support RDRAM. On the P4, RDRAM has consistently edged out DDR in performance. But DDR memory controllers are constantly improving, to the point where the DDR333 SiS 645 could challenge the PC800 RDRAM...
