Adding caps may help with improving voltage ripple, but they are placed very close to the socket.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

Thanks, any advice on specs?

1.4vcore mod at back side of motherboard socket

Just done 1.5vcore mod to use E5700 @ 4.425MHz 😀

Board can have easier volt mod with a potentiometer than "risky" socket mods. Image is my boards volt mod with 60k ohm pot to ground plane.

Hi there, I have problem with my 4CoreDual-SATA2 mobo. Whenever I try to boot, regardless of whether it's from CD or hard drive, I get the 50AC code in the lower right corner and the whole computer hangs. What could be causing this? Do I need to downgrade the processor or update BIOS as first post said that on newest cpu PC won't boot? (I have two Pentiums on LGA 775 in my collection)

I have Core 2 Duo E8200 installed.

Wind: 8VTAV / GeForce Riva TNT2 Model 64 / AMD Duron 800 / Windows 95
Neptune: 4CoreDual-SATA2 / GeForce 7600 GS / Intel Core 2 Duo E8200
Smol: Amilo Li2727 / Intel Pentium Dual-Core T2370 / Windows Vista & XP

Okay, i don't know how it's boots but it turns out that my processor is unsupported. I'll try downgrade it to some 775 Pentium's from my collection

Your processor is supported as soon as you have the latest bios beta.

Hope someone here can help me. I'm getting desperate at this point and I am about to lose the will to live!

I cannot get the Asrock 775Dual VSTA to output a video signal at all.

I've tried resetting CMOS, new CMOS battery, reseating RAM, reseating GPU, reseating CPU. I've basically tried all the recommended steps when you get no video signal.

Components:

2GB of Kingston 1GB PC2-4200 DDR2-533MHz DIMM (tested on another board as working)

I have tried it with both these chips:

INTEL SLA98 Core 2 Duo E4400 2GHz Socket 775 Processor

INTEL SL9S9 Core 2 Duo 6400 2.13GHz Socket 775 Processor

Both boot fine, no beeps, no warnings, but I cannot get a video signal with either.

I am using this GPU:

Nvidia GeForce 6600 GIGABYTE GV-NX66256DP2 PCB Graphics Card 256MB DDR2 (PCIE)

Tried the VGA output and the DVI output to 2 different monitors.

I have now ordered (out of sheer desperation):

Asus Nvidia GeForce 6200 N6200/TD/128M/A (AGP)

Gigabyte Nvidia GeForce 6200 TC. GV-NX62LTC256T (PCI-E)

Will any of this combination work?

I just need confirmation that what I've put together should work, or if I'm trying to put components together that won't work anyway.

This isn't even the final build, I just need something to boot and give me a way of installing WinXP, so I can make further updates.

Many thanks!

In theory they should both work.
If possible, test your gpu on another system.
And/or test another video output of your gpu.

Thanks for the info. I'll see if I have another board to test the GeForce 6600. And I'll wait at least a couple of minutes to see if there's any video output.

I'm waiting for the GeForce 6200 to turn up, so can't test that one yet. I'm not going to end up using either GPUs, it's just the one I want to use needs drivers installing first.

BIOS version? What POST code do you get?

Use Celeron D (FSB = 533MT/s), or Pentium 4/D (FSB = 800MT/s).
Sometimes Core 2 Duo/Quad are finicky on this board.

Alternatively use DDR1, instead of DDR2 (it may affect things if memory slots are the problem, 2.5 or lower CL memory timing is recommended).

Also, this board is NOT made to support 800MT/s RAM.
Make sure your sticks have 533- or 667MT/s JEDEC profile inside SPD.

If there's a way to get this information without having a video signal, let me know and I'll post it here.

One way is to pull the ROM chip out of socket and dump/flash it with a programmer but if it’s not an option you can indeed use the oldest components available like Pentium 4 and DDR1. There is a version sticker on the ROM chip so you can assume that one is minimal (if never updated) version number and look at cpu compatibility table.
To know the POST code you need a pci POST card.

Actually the first question would be:
Do you ever post with your motherboard with your Core 2 Duo and memory at all?

If yes, it is not an issue related to bios or memory (probably), check gpu.

If not, you should update the bios first and make sure the memory is compatible.
