Hello, I have a Intel PDC E6500 2.93,( currently OC'd at 3.05 GHz), and an ASUS P5G41-M LGA 775. Here is the issue. I cannot load the OS. Windows loads and after a 1/2 second of Loading, I get a BSOD. This is a new mobo+CPU. The rest is form a Compaq SR2710NX.

Well the memory calls for 1.5v and the BIOS is set at 1.2v. The NB voltage is currently 1.1v. That neds to be bumpe to 1.3-1.45 depending on amount of OC. Also the RAM is not set up manually (Configure DRAM Timing). Manuslly set CAS LAT to 7. I'm not sure exactly what you are trying to accompolish with an OC of the CPU. From the looks of what you have there, the RAM and NB are badly undervolted. I would think this is the cause of the crash. That Crucial budget RAM is good, but not ideal for overclocking. The RAM calls for 1.5v. You have 1.2v. I would start there and apply 1.5v to the RAM.

You still havn't clearly responded to badge regarding instalation.
From the above statement I gather that you are using the Compaq recovery partition, although the first sentence does not state it, but the second one implies it.
You can't use use the Compaq recovery disk on the new motherboard and cpu.
That being an OEM system is permamently locked to the Compaq hardware and not transferable.
You will need to purchase a new OS.

Exactly Jonmor68. I was going to post these instructions if Dogman 1234 had an appropriate installation DVD.

Note The computer must be configured to start from the DVD drive. For information about how to configure the computer to start from the DVD drive, see the documentation that is included with the computer. Or, contact the computer manufacturer.

To perform a clean installation of Windows Vista by starting the computer from the Windows Vista DVD, follow these steps:

Start the computer.
Insert the Windows Vista DVD into the DVD drive and then close the drive tray.
Restart the computer.
When you receive the "Press any key to boot from CD" message, press a key.
Follow the instructions to install Windows Vista.
If Windows Vista is now running on your computer, you have completed the installation successfully.

If the installation does not finish or you receive an error message, and you are comfortable trying to troubleshoot the problem, go to the "Troubleshooting" section. If you are not comfortable trying to troubleshoot the issue, go to the “Next Steps” section.

With the socket 775, it is likely your RAM is not up to the task. When you overclock the FSB, it takes the RAM with it. In BIOS, set the RAM speed down to a 1:1 ratio and relax the timings also if overclocking. Try 5-5-5-15 on the timings. If using PC2 6400 800MHz., don't set the RAM speed at 800mhz. and expect it clock higher than that when raising the FSB to overclock the processor. Set the RAM speed at 533Mhz. The overclock of the FSB witll take it higher from there and the RAM won't fail. Standard voltage for PC26400 at 800Mhz. is 1.9-2.1v. The CPU is not the likely FAIL. The RAM is.

Well, if the RAM is PC26400 800MHz. and it is running at 832MHz with the overclock of the FSB to get the CPU higher, that is likely beyond the RAM's caspability. That is the likely reason the overclock fails. If you set the RAM at 533MHz. in BIOS then overclock the system BUS to get the CPU higher, the RAM will run well below it's limitation of around 800MHz. This fine. As far as the Vcore at 1.2v that should be fine for a minimull type OC. Only under an extreme OC would you need say 1.4v or higher. 1.2v is fine and not the likey problem. Try setting the RAM speed to 533Mhz. and bump up the RAM voltage a notch or two. Can you list you RAM and MB again. System specs.

The MB should have RAM speed, timing and voltage adjustments in BIOS. And the RAM is rated at 1066MHz. so that would give some upward room from 800Mhz. default. It takes some time and tweaking around the BIOS to get the OC you want. Any excessive Vcore voltage would be required under an extremely high OC.

I had to reset the BIOS. here are the configurations at stable state in the firmware:

Advanced:

AI Overclocking: AUTO(266)
DRAM Frequency: AUTO(800)
Memory Voltage: 1.21000V
NB Voltage: 1.12500V
VTT: 1.200V
CPU OverVolt: AUTO (0.0100V)
SB: AUTO (1.5 V)
AUTO PSI: Enabled

CPU Configs:

2.93 GHz
FSB: 1066MHz
L1: 64 KB
L2: 2048 KB
CMOS Ratio: 6-11 (11 Max)
CUPID: 1067A

North bridge:

Memory Remap Feature: Enabled
Configure DRAM Timing By SPD: Enabled
Graphic Adapter: PEG/PCI
GTT Graphic Memory: No VT made, 2MB
DVMT Memory: 256 MB

I hope this maps out the BIOS pretty good.

RAM is double data rate (DDR) 667 x 2 = 1334Mhz. Your RAM is rated at 1066Mhz. and being Crucial value RAM would likely fail at 1334Mhz. Set the RAM to 533MHz in BIOS. 533 x 2 = 1066Mhz. Also set the RAM voltage to 1.5v. Read the specs on the RAM. The RAM is rated a 1066MHz. at 7 CAS with 1.5v applied, not 1.3v. Note: With the G41 chipset, the NB is located on the MB and houses the RAM controller, not the CPU. Setting the RAM at even 400Mhz. in BILS 400 x 2 = 800MHz. will loose very little in overall performance. The Crucial valuse RAM will work well OC'ed upward whe set at 800MHz to begin with.

Note: It is pretty amazing you Crucial value RAM is rated at 1066MHz. and running at all when pushed to 1334Mhz.

Update:

I have hit 310 FSB @ 3.40 GHz MAX. The RAM Voltage it about 1.89000V and the NB is about 1.25 Volts. I have had to increase the VTT to about 1.25000V to see if it can accommodate the BSOD. I get the BSOD @ 311 FSB rating. Should I increase any of the following:

Memory Voltage
ND Voltage
SB Voltage
VTT

Well, you have a 500MHz. overclock at 3.4. Why 1.8v when the RAM is rated a 1.5v? You risk damage to the RAM. Perhaps 1.6v or so. The NB voltage can easily handle 1.4v. Lower the RAM voltage to 1.6v and increase the NB voltage to 1.4-1.5v. Of course if you want to do an extreme OC the CPU will need a big boost in voltage. 1.3625v is the max Intel suggests. ha, you would have to exceed that to get to 5GHz. LOL.
