HP Compaq dc5750 Small-FF No. AHCI Option in BIOS
I work for an organization that have a good number (400 +) this PC model in use. We have problems of slow hard disk access. All documentation and the forums I can find online speak AHCI is an option in the CMOS settings and I would like to try this, but all of our dc5750s have no option - they have only Legacy IDE, Native IDE (currently we use) and RAID. The connections to the MoBo are physically SATA.
I am aware that we must provide the operating system with SATA drivers to perform the boot (since using XP), and we did it with success on other models of PC, but this isn't the issue. I'm interested to know why the AHCI option is not available in the BIOS when anyone with this model seems to report here.
I updated the BIOS to the latest v2.35.
Thank you very much.
Hello:
I have provided the link for the BIOS dc5750 configuration guide.
There is no option of DCIS. Default value is Native IDE if you're not in the RAID configuration. The setting of DCIS came out in models that have made this series.
http://bizsupport2.Austin.HP.com/BC/docs/support/SupportManual/c00765938/c00765938.PDF
There is a management setting of SATA power that enables or disables the SATA bus or device power management.
I don't know what the default setting should be for that.
My suggestion is to upgrade the BIOS to its default values.

AHCI option is not available in the bios

Window 7 64 bit
Installed new Samsung SSD 830 128 GB
I tried to install msahci using regedit and reboot - but still no AHCI option in bios setting
I don't think.
The problem is with the BIOS/chipset
Unless the PCI controller has its own BIOS where you can set it to AHCI, so no, it wouldn't make any difference on what you have now.

I have a HP Compaq 6300 Small Form Factor in which I just replaced the motherboad. It works very well. I can start on a USB bootable and (1) start a Windows 8 or a clean installation of Windows 10. I can (2). boot from a USB drive capable of Linux Mint 17.3 Startup and load that OS fine. When I try the installation of any of the aforementioned OSs (Windows 8/10-Linux Mint 17) they all will get an error of memory or hard drive and the installation at the beginning of the installation to fail. I tried this on two SSD drives and two HDs standard. I am at a loss on what to try next. Any help would be great. Thank you. -Matt

Compaq DC5750 series desktopPC: compatible memory question
Will HP P/N 404574-888 1 GB memory in my Compaq DC5750 series desktop PC? I know that the PC has 4 memory slots and I think that the memory must be installed in sets of two. I have 2 GB total now with maps two memory supplied with the PC and there are two empty slots. I was hoping to put in two additional 1 GB memory cards each to spend a total of 4GBs of memory. Running Windows 7, I think that I have a memory bottleneck in the performance of the PC. When I go to the Task Manager, my memory is already 87% used after a fresh reboot. I appreciate comments. Thank you
What is an MT or SSF? Here is a parts reference guidefor the Mt. To the #2 page, the 1 GB is part # 398038-001, and here's a price. The reference you gave 404574-888 is PC2 6400, if your system is PC2 5300 latest 6400 will return to 5300.

Hello
I'm not too familiar with the hardware upgrades, so I wonder if a Nvidia GeForce 8800 GT 512 MB would be compatible with my HP Compaq DC7800 Small Form Factor?
Thanks for any help!
Hello:
Here is the link to the plug for the GeForce 8800GT...
http://www.GeForce.com/hardware/desktop-GPUs/GeForce-8800-GT/specifications
Certainly, this card will not work in your machine for two reasons.
1. he needs a power outlet extra that doesn't have food dc7800.
2. the draw of the power of the card (105W), is too much for the PCIe x 16 slot 25W prorated and 240W power your PC.
These PCs is designed for light desktop for administration.
If you want to add a video card, it must be a down a profile that comes with low profile brackets in the area.
I recommend the AMD HD 6450 or Nvidia GT-610 low profile cards that will work within the limits of the power supply of your PC has.

Hello:
For a video card, I recommend the AMD Radeon HD 6450 half-height card, which works perfectly with the 240W power supply in your PC.
Make sure that you get one that includes low profile brackets in the area.
Memory... you can install a maximum of 4 x 2 GB memory PC2-6400 for your model if you are running a 64-bit operating system.
I have used this brand in my dc7800 CMT. I bought 2 games and maxed out.

Processors... Mine came with the E8300, so I didn't change that.

Where is the option AHCI in the BIOS L350D?
BIOS version is 1.70

Hello
Usually in the BIOS, there is an option called SATA controller mode. You can choose between AHCI and Compatible mode.
But I believe that not all motherboards and BIOS version contain such an option, so probably your computer doesn t offer such an option.

D10 bios, no ahci option?
Not short, I have no ahci option in the bios. Only compatible mode and enhanced mode (non-ahci). I have active test to about 135 MB/s with ahci and Intel matrix installed on the previous system, in that it is an installed drive. Installed in the d10 I get just shy of 90 MB/s, which is about the speed, I'll when this disk was used without ahci & matrix intel installed before. Information on the motherboard are sparse. The brief manual covers only a few options in the bios. Any help, PLEASE.
In fact, I found the solution. AHCI will be visible and available with raid disabled on the controller intel. No ahci option at all on the lsi controller, but I didn't see much variance in performance of single disc between the two.
