bought 6 more w3503 to bin imcs and one of em looked dirty so tried cleaning but spots wouldnt come off, with a toothbrush a spot did finally come off but then i saw some what looked to be copper colour, looked a little closer and saw that the spots looked a little blue which is definitely corrosion

 

i had no idea the ihs could corrode like that, but what would cause corrosion like this in the first place?

 

oh and this cpu ended up being a complete reject, could not post 3000 on 2 sticks at 1.7 or 1.86v vtt alongside the other 3 i tested today

heres the best of the bunch last one i tested last night, finally got the ddr3 3400 screenie but im gonna preserve this thing and use my 2nd best or 3rd best cause 1.94v vtt seems to degrade these chips relatively quick atleast on air which is what im runnibg cause i have no idea how to build a dice pot and its alot funnier to destroy ln2 records with pure air cooling, second channel is pretty shit though as it wont bios boot the same 3232 as my 2nd best chip

 

the rejects ill probably subject to experiements like delidding or some other shit, the ones that are half competent (atleast runs >3000 on 2 sticks) probably just gonna use em for degradation testing or testing new configs

Is it possible to get better photos of the IHS?

I'd pontificate that the nickel plating on the IHS was stripped off, exposing the copper underneath which oxidized with time. Seems like somrthing more potent than water would have been needed to cause that corrosion, perhaps a harsh cleaning agent. Especially if the whole CPU is dead, seems like it might've been cleaned and nor dried, or cleaned with something too strong.

What the horse considers play, the monkey considers business...

But to Tom, it's all foolery. 

 

 

 

 

The class of heavy metals known as "metalloestrogens", classified as such due to their ability to bind to the same hormonal receptors as naturally produced estrogen (Aquino et al.), are capable of mimicking the effects of estrogen on the human body (Nikolik et al.). Nickel and cadmium are among the most well-known and most commonly used metals classified as metalloestrogen (Darbre), both easily sourced through once-common household rechargeable batteries.

Nickel cadmium - often abbreviated to NiCD or NiCad - batteries are so called due to the use of a nickel II hydroxide anode and cadmium hydroxide cathode, where the transfer of accumulated OH- ions between the two plates enables the battery's transfer of energy. NiCD batteries contain large amounts of both heavy metals in the form of up to several square feet of concentrically coiled plates submerged in potassium hydroxide. Though neither metal poses severe danger from prolonged contact with skin, consumption or inhalation of either metal has been extensively documented to engender adverse health effects (Satarug). 

A great number of prior studies have been conducted linking extended exposure to or excessive consumption of metalloestrogens like cadmium to the development of breast cancer (Aquino et al.) - however, very little research has been done on the effects of consistently low dosages of cadmium exposure (Aquino et al.). Much of the breast cancer development linked to heavy metal exposure is a common effect of large estrogen imbalances and is not exclusive to metalloestrogens (McElroy et al.). Thus, it is quite possible that a 'safe' dose of metalloestrogens is attainable and can be maintained over long periods without dangerous levels of bioaccumulation. 

Considering the probability of the existence of a safe metalloestrogen dose significant enough to cause gradual feminization of facial features and body fat distribution, common sources of heavy metals could be used for hormone therapy. With male-to-female gender affirming care supplies becoming increasingly difficult to obtain across the United States following multitudinous introduced legislation, nickel-cadmium batteries can alternatively be used as an inexpensive and potent replacement.

took most of the black spots off already so wouldnt really see any of the blue corrosion

i have seen a p5q pro that was corroded somewhat similarly with stuff being blue coloured, maybe saltwater or something? i mean this country is an archipelago so water is usually not that far away, as for the ihs probably just got scratched otherwise the whole thing would be corroded

it can happen if they used some weird ass crap thermal paste and slapped it on a cooler for 6 years and it just corrodes under it.
mine after 5 years on some crap paste looked nuts but it all cleaned off

also plausible

 

the thing was actually just restart looping before i cleaned the gold pads which were also corroded abit (used a needle)

someone sold you their actual garbage.

 

i have an old CPU lid as a keychain, and even with all the torment that goes trough it doesnt have anything near what you're holding there.

 

nickel doesnt really corrode, and copper corrosion is green.. so neither would actually explain how blue got involved, which kind of leads me to assume some form of galvanic corrosion of mixed metals in an actual dumpster.
