    What are 'Encrypted Instruction Sets' ?

    That trusted computing stuff makes for an interesting read. Those fast random number generators should significantly speed up some of the encryption operations. Seems they started integrating trusted computing modules in AM2 onward and Core 2 onward. I've read some reports of Pentium Ds...

    What are 'Encrypted Instruction Sets' ?

    Did this ever happen with any consumer of industry CPUs? If not, were there official plans to implement this? Just wondering where a 'leading U.S. cryptographer' got this idea from. Maybe it was implemented without public documentation?

    What are 'Encrypted Instruction Sets' ?

    Source: http://cryptome.org/jya/msnsa.htm - 1999 Hi all, I'm just wondering what 'Encrypted Instruction Sets' are and what these 'next-generation CPUs' being referenced in 1999 were? Pentium 4/Athlon XP? AES-NI? SSE2? Via's Padlock Engine? Thanks :)

    Fastest CPU without a heatsink/fan/cooler?

    Thanks for the links and references guys. I checked them all out, including the XS article. I've got a fair idea of heatsinkless cpu operation now. Might come up with my own little project to try. If i do - I'll post my results :)

    Fastest CPU without a heatsink/fan/cooler?

    I was referencing the E8000 series. I was going to say Penryn as that's how Intel liked to reference 45nm but meh. I stand corrected though :)

    Fastest CPU without a heatsink/fan/cooler?

    Have you actually done this with a wolfdale chip? I imagine a celeron would be better for this being one core and having less cache.

    Fastest CPU without a heatsink/fan/cooler?

    After a previous thread I started I learned that after about the 486SX CPUs started including heatsinks, and later fans on those heatsinks. From what I can tell, it seems the TDP limit for these heatsinkless processors is 3-4 watts. I'm not sure whether you can dissipate much more heat than...

    Which was Intel's first CPU to require a cooler?

    The C3 chips say they need a heatsink on the heatspreader. However, I've read numerous reports about these chips being able to run without a heatsink - one report saying 800mhz and lower without a heatsink works fine. There's some low TDPs listed for the 150nm and 130nm C3 chips. I know...

    Which was Intel's first CPU to require a cooler?

    Hi guys, Just wondering here.. what was Intel's first CPU to actually require a cooler? It seems some of the earlier ones it was an optional thing. 386 didn't seem to need them, nor 486 in some photos I've seen. What about Pentiums (P5) and Pentium Pros (P6) ? Pentium 2 obviously had it...

    Pentium 4 3.2@4.5 Stable. If I get the 3.6 do you think I'll get 5GHz stable?

    Nah, Cedar Mill (particularly the 65W D0 stepping) runs cool. I'll put it through super PI 1M next time I play with it, which will be whenever the 3.6 chip arrives. Then i'll have a better cooler and ram installed also.

    Pentium 4 3.2@4.5 Stable. If I get the 3.6 do you think I'll get 5GHz stable?

    Didn't realise the Super PI benchmark would take so long lol. Stopped it after Loop 2 finished. 45s initial value finished 2m 59s loop 1 finished 5m 33s loop 2 finished perhaps this gives you some indication, I don't know. Strangely, I just got 168.6 seconds in wprime 32m. Last time I ran...

    Pentium 4 3.2@4.5 Stable. If I get the 3.6 do you think I'll get 5GHz stable?

    You're likely correct. Larry: I'm not familiar with superpi, i am however with wprime. Is it multithreaded? I haven't optimized the memory in this yet. I'll post a superpi number shortly for you. EDIT: It appears it's not. There's some HyperPi front end for it to run multiple instances...

    Pentium 4 3.2@4.5 Stable. If I get the 3.6 do you think I'll get 5GHz stable?

    Haha yeah. Northwood was quite a while ago! Ok so I found out my memory divider was set to high (5:4) so I lowered that to 3:2 and 4.6Ghz was fine in prime95 for 30 minutes, moved on to 4.7Ghz and got bored after 10 minutes so now I'm trying for 4.8GHz with 2:1 and had do give the northbridge...

    Pentium 4 3.2@4.5 Stable. If I get the 3.6 do you think I'll get 5GHz stable?

    @Magic Carpet: Have got one on the way :biggrin: @Tuna-Fish: Idling in the 30s and Prime95 in the 80s - Not a great heatsink though. Will install the Noctua NH-D14 when I install the 3.6GHz chip. It's being posted next week to me. @YBS1: A 4.6GHz Northwood would be godlike. People were...
