View Full Version : Morgan voltage mod strange little discovery!

I have overclocked a morgan 1G to 1260(9x140) using drilling and defogger kit, because my mobo(gigabyte 7vtxe) doesn't allow mult. change. There I noticed something VERY STRANGE during moding the voltage through L11 bridges(though don't need more than 1.9 yet, but who knows...)the voltages displayed in various sites, such as those mentioned by nick_cw in earlier thread, are correct, but only if counting from 5 to 1 bridge, (instead of 1 to 5)!!!! At least, that's what happens to MY cpu. I firstly started counting from the L11 bridge which is next to "L11" mark, but got strange results. I firstly thought it was something wrong with the drilling(those dam bridges are REALLY deep, have to look very carefully and also put water on them to see if copper stop shining), but after some efforts I noticed that if I count upside-down, all mods were successful!!!!
I suspect that this may occur only in some cpu's, such as Morgan 1G or 1.1G, but not sure.
I wrote those in case someone has problem raising the voltage in such cpu.
If anyone else has similar experience, please post! Also be glad to discuss any other overclocking and stability issue.
Thanks a lot,

Hi Nick from Greece- Quick question: what is the default voltage on the Morgan? All I have to go on is this chart and it's not 100% accurate.

It's 1.75, though the 1G one works fine at 1.7V non-overclocked. I guess it has to do with production cost, otherwise we would expect higher models have increased default voltages, 1.8 maybe, but they don't.

Then you are starting with the factory cpu looking like this:

That's right but this picture doesn't help at all to determine which L11 bridge is which as for 1.75 volts L11 bridges are connected symmetrically. Bridge no. 1 should be that next to "L11" mark on the left right? But in my CPU I must count from right to left in order to achieve any voltage mod.
