Chipset Voltage?

[OVerLoRDI]

I've been playing with overclocking my x2 3800 on an a8n-Sli Premium and been using this article as sort of a guide line. http://anandtech.com/cpuchipsets/showdoc.aspx?i=2650&p=4
I noticed that they increased the chipset voltage and I'm curious, personally I haven't read anything on these forums about increasing chipset voltage when overclocking, but what do you guys think? Also the vcore they used seemed very high. Just kind of getting my feet in the door of overclocking so playing around with voltages is kind of new for me.

You never play with voltages specially the chipset voltage. I don't think you need to increase the chipset voltage to OC your 3800. You will only need to increase the Vcore, not by much, just a little bit. To show you how bad it can be, do the following..

1. Note down idle temperature of your CPU on stock voltage.
2. Restart, increase Vcore to 1.5V, restart and then note idle CPU and load Temp. in Windows.

You should see a considerable increase in CPU idle temperatures and about 5-10 deg C in load temperatures. This implies that when you increase the voltage of any chipset, you forcefully make it to consume more watts and in return it outputs more watts to loose excessive energy. The more you volt, the more will be the output wattage and i won't be increasing cipset voltage for no reason.

I believe you can only get a very slight FSB overclocking headroom even if you up the chipset voltage. Perhaps the resident OCers here can provide us with more details.

From what I've seen its a bit of a mixed bag. Some people claim no difference in maximum HTT and other claim theirs went up with an increase in chipset voltage. IOW YMMV

Not everyone is telling the truth. Im sure an AMD @ 2 GHz can hit 2.8 GHz without the need to increase chipset voltage.

I'm running 260 x 10 with all default voltages, except a vcore (CPU) bump to 1.375v.

I don't think you would have to raise it until you start hitting really high HTT frequencies.

Agreed..

On my Neo2 platty I was able to go from about 311 HTT to only 315..

Chipset voltage had to be increased over 10% for that.. Not worth it in the long run..

Thanks Guys I really appreciate the help. I found my stability issues were rooted else where. This motherboard's not very good at detecting my memory latencys and set some of them 1 notch too low.

I had to increase my chipset voltage to get my current overclock stable.

Edit: good to see your issue is resolved.
