<< there's a rumor that some oem chips are almost "used"..as in, the company tests them, keep the ones that are good for overclocking, and then sells you the cheaper ones. >>
That is exactly what this is...a rumor...perpuated by ppl!! If that was the case how come many users here by oem chips and clock the livin hell out of them. Many will agree the taisol is good but not ocers choice for heavy ocing. So the hsf is a waste of money if they are already looking at buying a new more powerful 80mm hsf combo...Total nonsense...
I have heard (not confirmed) that a lot of the chips are tested to see their yields and often may be downgraded to lower mhz or ghz rating if they do underperform.
Many oem builders out there...you think someone would have made a stink about it if it was subpar junk we were getting...
<< anyway, i built a system for my buddy using an oem tbird a couple months ago and it was horrible..when it arrived, the chip was just flopping around in a plastic case that was holding it, and it turned out to be bad so we had to RMA it..anyway, his system still isn't stable, and i blame the chip. >>
oem plastic cases I have been shipped have been quite secure in holding the chip with limited or no movement...overall you just had a bad experience.
My take on the retail and 3 year warranty has always been the fact that amd nows when you are buying it you are buying a cooling solution they know and recommend as being effective, and if used within operating specs should run just fine for 3 years. I have always bought oem fior myself, my clients, and my family...and I can 100 percent that all those processors are running today...even a 6 year old p75, 5 year old cyrix 166, 4-1/2 year old p-pro 200, many 2 to 2-1/2 year old amd k62's and on and on...
