My name is Angelo I've fixed about 4-5 xboxs with the simple xclamp fix but now i have just recently purchased an xbox off craigslist for about $50 and upon opening her up i noticed the penny fix

now I'm going to do the electric oven reflow tutorial but i need to know instead of using some pennies wrapped in electric tape (just doesnt seem rite to use them)
where can i find the things that were on the ram blocks before and what were they called?
