The Extreme Pin Modding Guide - Page 6

So none of the voltages that I have given you have yet to be stable? In this case I would ground VID 3 only and use an undervolting program to test for stable voltages. While this will do nothing for your stock 1.340v, you can use an undervolting program (CHC, RMClock, etc.) to select voltages between 1.324v and 1.212v, and, because of the pin mod, these will actually be voltages between 1.452v and 1.340v. So, selecting 1.324v will give you an actual 1.452v, 1.306v will give you an actual 1.436v, etc etc. Start off high and keep bringing it lower until you find what's the lowest you can go while being stable. Afterwards, you can then permanently voltage mod your CPU via pin mods so that it will always be stable and not dependent on an undervolting program.

91C is still within the thermal specification of the chip, but it will eventually kill it much sooner than cooler temps will. The CPU core should look like a silvery, shiny rectangular shaped block in the center of the green ceramic. It should be about 1cmx2cm (roughly). Any "beeswax" on the top of it is the left over crap from that thermal sticker/pad. In either case, NEVER use any kind of metal object to clean it, as it can scrape and damage the heatsink and the CPU core. Rather, use a lint free cloth or q-tip soaked in isoprophly alcohol (any kind will do, but 91%+ is best) to clean away the black sticky TIM. After both surfaces are cleaned, apply as you have stated and you should be good to go .

Your CPU temps are WAY too high, that's what's causing your problems. Look into getting some Arctic Silver 5 or similar high quality thermal paste and removing that stock thermal sticker that Dell uses, you should see a dramatic difference in temps and performance. Also, was that 3DMark05 score on battery or A/C? 3336 for a 7800GTX is insanely low .
Good thing there was no anniversary attack , any idea of what year it was?

Glad it's working

In that case, everything is spot on, but do make sure you get some good thermal paste on that CPU, otherwise you'll run into problems down the road. Thanks for the article, funny how times have changed

whooaaa, grounding pins sequentially has nothing to do with adding more voltage. Read the charts in the first post of the thread. The six VID switches (VID0-VID5) give you voltage according to their up down positions, much like tumblers in a lock. What position you put them is what determines voltage. Have you tried just booting without any vid mods? If you can, find out what your stock voltage is and get back to me and I'll help you out from there .

Try booting with it without the pin-mod (so that it's at 1.8GHz) just so that it's stable so that you can make sure that your Windows install wasn't corrupted by a bad bootup.

Ok, and you said that grounding VID0 and VID1 (E2 - E3 and F1 - F2), which would give you 1.388v, and it still wouldn't boot? Crap, that might mean you have a shitty chip. Try grounding VID0, VID1 and VID2 (to give you 1.452v) and see if you can boot. Lemme know how it goes .
