Chaintech VNF3-250 Doesn’t POST and beeps once…

I guess I asked for it, upgraded from a 75GB drive to a 750GB (!!) drive and things were working fine until I actually put the drive into the computer and now nothing happens. I get one beep and then the system just hangs!

“OC Forum”: has a very useful what to do on a failure like this:

# Make sure everything is seated correctly and all the contacts are clean. Disconnect everything else but the minimum stuff, that is the memory, cpu, video card, disk.
# Listen for the “beep codes”: which are dependent on the actual BIOS you have. Naturally, you won’t know what BIOS you have until it fails, but a look at the “Chaintech”: manual will usually tell you. In my case, it uses the Award BIOS that “BIOS Central”: has. In my case, I literally get a single short and that’s it.
# Try a CMOS Reset. Always good for the soul particularly when you’ve overclocked a machine as I have. In the Chaintech case, that is JP1
# Did this last thing and I was back. I guess when I put it all together, I wasn’t careful enough about static and I whacked the CMOS. Pretty wierd. So I would guess that a single beep means the CPU couldn’t start because it was going to fast.

Chaintech VNF3-250 and OCZ PC4000 2GB Platinum

AnandTech – Chaintech VNF3-250 Motherboard Question. Well, I’ve just lost another memory module. Been running 2x512MB PC3700 OCZ Gold Rev 2 for a while now in the Chaintech rig, but I’ve been getting random BSODs. Ran memtest and see intermittent errors on the first stick, so I bought some fancy OCZ PC4000 Platinum’s for the higher end DFI LanParty UT Ultra-D and moved the OCZ PC4000 Gold to this machine.

Essentially, I have to redo the settings of the memory. Running at 2250MHz CPU, 250MHz FSB and the new ram at 1T 2.8V, I only run Prime95 for 3 minutes. This post shows that it can be done, but the timings are different and in fact some report very mild overclocking only to 215MHz at “newegg”:

No nVidia GART in PCIe systems and never nVidia IDE

DFI Forums – NF4 SLI-D – tweaking windows (video for NF4 LanParty) *mirror added*. _OK, this clears up the myths about what to do about when you need the various nVidia drivers, it is confusing because in fact, on modern systems, you don’t want any of it but the video drivers…._

In a PCI-Express system, there is no need for a GART driver since it ONLY affect AGP bus (and there’s no AGP bus in a PCI-E system…)

As for nVidia IDE driver. I’ve not found it necessary at all unless running RAID (and really only RAID-1 for rebuilding an array as RAID-0…if it gets hosed…you’ve lost everything).

The IDE driver also can cause many conflicts, bsod’s, freezes, as well as stop your cd/dvd writer from performing properly.

DiamondMax 10 not recognized fixed with Autodetect NONE

DFI Forums – [Resolved] resolution for disappearing Maxtor drives? (post #12). _The old fix was to update the firmware, but you need to actually buy a vanilla SATA drive card so I just instead spent another $120 and got a later Maxtor, but now I see there is a simpler fix, what is happening is autodetect on empty drives is causing the Maxtor to get lost, so here is the recommended simpler fix._

bq. My Maxtor DiamondMax 10 exhibited most of the symptoms you guys have described:

#Wierd behavior where Windows would insist on checking the disk for consistency upon reboot
# Failure to detect the drive
# If it did detect the drive it would often hang during booting Windows.

It had similar symptoms on my older Epox NF3 board. The fix I used for the Epox worked for my new NF4 Ultra-D as well.

# Go into the BIOS
# For every IDE channel and SATA channel that is enabled but has no drive connected\
# change the detection method from “Auto” to “None”

This bypasses autodetection of drives and seems to be what was causing all my problems… my Diamondmax not being detected or being detected incorrectly. This solved every one of the problems I was having.
