I think MCP is causing my system instability and prevents me from overclocking further than 25%

Here are temps from everest:

MOBO: 37
CPU: 25
CPU diode: 21
MCP: 58
Aux: 36
GPU: 48
HDD: 40

mcp reached 61 which made orthos stress test find errors.

Where is it located in the board? Near the PCI slots? CPU? ram?
So ill know where to put another case fan

I believe 'MCP' is referring to the northbridge on your mobo. I believe this is your board. The northbridge is circled:



Some things to do; take off the stock heatsink, apply new thermal paste/thermal tape. Or take off the passive heatsink and buy an active one. Here's a good one from Xoxide, on sale:

Northbridge is SPP, Southbridge is MCP. That might be one reason you are confused.

Replace the tim on your MCP (southbridge) and get better temps. Otherwise, lower the voltage on it and try for a smaller OC. I'm not familiar with that board, but I'm sure you could replace the fan with a 80mm or small fan to help aid the temps on the SB heatsink. Also, SPP is your northbridge on the nvidia Nfoce motherboards with that mobo.

My southbridge runs pretty hot too, around 45-55c, but i hAve the voltage up a notch.

Actually his board only has one, considered to be the MCP, but heathmcabee is right, in most cases southbridge is MCP.

1. ECS is a bottom-of-the-bin manufacturer. Their boards are intended for budget applications, not enthusiast-level overclocking. You're already lucky to be getting a +25% overclock on that thing.
2. The Nvidia GeForce 6100/nForce 430 is a low-end IGP chipset. This is not a platform intended for overclocking.

I believe these two factors have much more to do with your OC ability than the MCP temps.

Great advice and info Deviance. Built in controller for both the AGP (maybe raid in supported *forgot to look* and the northbridge prcocesing all in one area. Strange, I know, but I dont think this board was meant for setting world records with the low end layout it has on the motherboard. The best I can recommend is my post above to maximize his cooling and replace the TIM.

That is your north bridge and on your board it is also a graphics card.

Thanks man, I was pretty surprised myself. I had never heard of such a thing. Well, until now that is.

Please show all voltage changes.

I didnt change the voltage of board and cpu, all i did was increase bus speed to 250, and lower memory timings a bit to avoid instability.

Could I use a fan and heatsink taken from an old Geforce 4? or maybe drill a hole in the side of the casing and put an 80mm fan that will directly hit the MCP heatsink
