so i can use these to boot and they work better then 2.0?

They do run faster, but whether or not you'll actually "feel" the difference with SSDs is debatable. Mostly they're used for mechanical HDDs to help improve performance.

The M.2 card however will give the ability to add M.2 Sata(not NVME) drives to a system without M.2.

Work with and backward compatible - yes. Without an onboard controller chipset, and only using one bus lane, how do they increase speed? Can anyone show me actual benchmarks where such cards approach SATA 3.0 speeds in a 2.0 system?

To be fair I've never actually benchmarked them. I'd imagine there's at least some improvement. They've mostly been used to make more drives available to the system. There are also RAID variations of these cards which are used for obvious purposes.

Hey - I currently have Precision T7500 with a pair of X5680's and 48GB (all 4GB sticks), and am just curious as to how high I can push FSB (or other frequency/clocks) before the onBoard SATA and other components start acting squirrelly. I was reading around when I ran into pages similar to this:

• https://www.overclock.net/forum/5-i...rclocking-dual-xeon-dell-precision-t7500.html

But, since I have no way of obtaining a PCIe SSD or anything of the sort (to free myself from the use of onBoard SATA), I'm forced to use a more tame FSB adjustment, if applicable. What are your suggestions?

well im back with another question....

so right now i have the stock 2x 120mm fans in front but thez make allot of noise..

i was looking around and found this:

soo my question is if i get a 4 pin fan that has a lower DB and cut the wire of the fan and solder them to the 4 wires of the 5pin del connector would that work?

i know the that the normal dell fan is 0.9A so do i need to get a 0.9A fan as well?

A little while back this discussion came up. You can get adapters for normal fans to plug into Dell jacks, and they're inexpensive.

The fan jacks on Dell motherboards are rated from up to 3.0A(IIRC) so you do not have to limit yourself. In one of my systems a pair of these are installed;

o that would save me some time nice tnx

do u know what the db and the cfm is of the stock 120mm dell fans?

 

[lexluthermiester]

No worries, YW.

do u know what the db and the cfm is of the stock 120mm dell fans?

That's a good question. I know that the Cooler Master fans are about the same noise level and they claim to be 19db but they seem to push more air than the stock Dell fans;

The first thing I would be careful about is make sure that the replacement fans offer adequate CFM. While the Dell fans (Foxcon) are noisy, they move a lot of air. I believe they are rated around 150 CFM. A quiet fan is going to be a lot less than that. But there are some relatively quiet high output fans on the market, just avoid the mistake I made, avoid the super quiet 1000 RPM fans. They just won't push enough air.

I am told that replacement fans might also run into a F1 boot error... apparantly some fans do and some fans don't. I am not sure which do and which don't. I am running my Dell headless, so this was a big deal for me (no keyboard attached to hit F1).

You can run a fan that uses less than 0.9 amp, but I would not exceed that value. I would avoid fans, like some Delta fans, that pull 3 amps. They are way to amp humgry. Most fans should be okay though, for example, the new Noctua 3000 RPM fan pulls less than 1 amp.

yea i was looking around and found these: noctua nf-a12x25 pwm it puts around 60 cfm and 20 db max

but i might do a mod that i can fit 2x 140mm like these: noctua nf a14 industrial-ppc the put out 159 cfm and has a 35 db at max so yea there a little bit expensive.

Those are good choices, but I was thinking more along the lines of Noctua NF-F12 iPPC 3000 PWM. The NF-F12 iPPC puts out a little less air than the 140mm one, but you don't have to mod anything, it should fit. I think it pushes about 10 CFM less than the 140mm. The 120mm is slightly more noisy than the 140mm. I guess the bigger they are, the quieter they are.

There are many surplus PCIe SATA controller cards available to move onto the PCIe bus using your existing SATA drives.
SetFSB has not been supported for a very long time. There are other FSB utilities based on RW Everything that don't have the SATA issue (I've beeen told). When you start overclocking locked BIOS Dell 2 CPU workstations you're going to have to do some of your own R&D work. Nobody really knows the answer, and others don't usually post what doesn't work so even that information isn't available. The terminology changed from FSB to BCLK with the move away from LGA775/771 so that may help with your searches.
SoftFSB, CPUFSB, GetFSB, and Clockgen are some of the others.

so right now i have the stock 2x 120mm fans in front but thez make allot of noise..

The other thing about the Dell fans is they are 120x38mm and most aftermarket fans are 120x25mm. The Foxconn fan is 150CFM ( says so right on the fan). Some of the older 2 CPU workstations like the 490 had a much bigger 150x50mm 275CFM fan with a smalller 92mm case fan. It draws 1.8A and would need both pairs of power leads to run it. It's very quiet but you will need to remove the HDD tray to make room for it, and power the cage fan from somehwere else. I show the mod in the TS overclocking thread on page 8. The first photo got moved to last place. If you start the sldeshow from the last photo it will make sense. Post #186

Would you happen to have a P/N on the 275CFM fans?

mm that looks good yea how do u power it do? did u solder the 2 5pin wires to 1 fan?

 

[Retrorockit]

Part numbers are in the page I linked to. You want the whole Precision 490 fan assy. since it drop right into the T3500/5500 case, and the matching 2nd fan also.
I would just pair up the 2x12V. wire, 2 x Grd wires, and 2x rpm wires, and leave the aux. fan PWM wire off. This will give 1.8A. power, and the BIOS will sense a fan on both headers, but the speed will be just CPU temperature based. There is a 3rd fan header for an HDD fan on the MB. I would power the aux. cage fan from there.

mm tnx for the info is it really quiet or is it like the 2x 120mm? and do u know the db?

 

[Retrorockit]

It's a 2000RPM Max. fan. IDK the decibles but it's not obnoxious at full speed, and the rating is usually irrelevant since you're not likely to ever hear it above 1200RPM anyway. It doesn't need to speed up very often. Idles at 900rpm. You will hear a bunch of air moving around if you turn it up.

mm oke yea ill try that instead it mutch cheaper tnx for the help

Okay, I just replaced my front fans with 2 Noctua 120mm iPPC fans. At first I got the F1 boot error, but with no keyboard attached, I just powered down and up again. On the 2nd power-up the F1 error did not re-appear!! So looks like I am okay.

 

[Retrorockit]

FWIW the AFC1512DG 150x50mm Delta fan is what I upgraded to from the 120x50mm 2 motor GFB1212VHG 3.4A fan. More air, less noise and less power required.

 

[Retrorockit]

In my Optiplex 380 with 120W X5470 running Prime 95 small FFT @ 1200RPM I get 52*C.,and @ 2000RPM I get 42*C. I did undervolt this CPU to 1.125V. to research Manguptas situation. I think it was 57*C at stock Voltage and maybe PWM? This is in 76*F A/C environment. This is with an old Opti 745 heatpipe cooler D9729. This would be the stock cooler for a 120W Pentium D Opitiplex. Of course in the old BTX Optis the fan is completely ducted to the cooler. A situation I was trying to duplicate with my fan/ cooler mod on page 8 of the TSOC thread.
