unityofsaints Posted March 19, 2019 Share Posted March 19, 2019 Hi, I have about 20 Bloomfield chips to bin through and have tried one on LN2 but the results were not promising: Windows boot only around -65 or warmer, best stability around -80 and complete CB around -105. Is this typical? Gulftown is easier, there are many more resources online about CB/CBB behaviour and my 980X chip followed those descriptions pretty well. Bloomfield on the other hand has much less stuff online. Is there a CB killer minor voltage or is binning for a chip with the coldest CB most important? I tried on the UD9 but also own a RIIIF and RIIIE. 1 Quote Link to comment Share on other sites More sharing options...
SoF Posted April 14, 2019 Share Posted April 14, 2019 Yes this is very typicall for Bloomfield. They almost all only scale up to around -80 to -100°C and are not working beyond this point. Also you will face a pretty low voltage range (mostly up to a max of 1.6, maybe 1.65Vcore) where they will scale. I think I have never seen a Bloomfield which really scaled past 1.7V. Bloomfield was a pretty boring CPU generation except for that one Gem 975X stummerwinter had...could outperform anything by 500 MHZ and was the only CPU back then doing 6 GHZ. But this was a huge exception, usually it was 5400-5500 MHZ even for really good chips. 1 Quote Link to comment Share on other sites More sharing options...
