First time going sub zero...advice???? - Page 2

post #11 of 15
I didn't read all the posts in this thread admittedly, but I agree with the first reply telling you to consider 775 over AM3.

The reason for that, is you're on DICE. If you're looking to seriously compete with other extreme overclockers or on hwbot, then you'll find that LN2 coolers run all over you with AM3 hardware (and there's alot of them). AM3 just scales too well with cold temperatures, and LN2 is alot colder than DICE is.

With a 775 system, DICE will still be competetive due to the platform not scaling as well with the cold and being coldbugged so that the full potential of LN2 can never be used. You'll still find LN2 coolers beat you, but not by as much (and not in as many numbers) as you'll find with an AM3 system.

775 is alot of fun (I've played with a few 775 chips on LN2) and chips can be found for dirt cheap prices if you look hard enough. Grab an EP45-UD3 or variant of that (EP45C (ddr3+ddr2) or EP45T (ddr3) ), a couple of cheap C2D chips and you'll be well on your way to having alot of subzero fun.

Just my 2c.

I have the 990FXA-UD3 in my main rig, haven't used it yet though still waiting on FX-8150, but I ain't gonna use it for this, at least not now. I was going to get the 965 cuz it was on sale for the same price as a 955 but if a 955 will yield more points, just cuz of its label, than I guess I'll get one of those, same chip anyway. I was going to pick up a 555 as well. I figure I can push it a lil bit farther since I'll only be cooling 2 cores instead of 4 so I'll get more from my DICE. Y'all are the experts though.

grab a 955, 965 (C3) and a 555... maybe a sempron 140.
learn on dice and when you get funds for ln2... have some fun.
That $70.00 board will run 965 C3's and everything else that will bring in nice points.

But, then again, on dice 775 should yield better scores and points.
I did 6.7GHz on a Commando with a Celeron on dice.
Just remember, if you get a chance to go with LN2, on intel you will have cold boot bugs and have issues booting at extreme cold temps.... with AMD, 99% don't have this issue.

Just go and search HWBot and look at processors and scores and speeds attained on Dice. from there gauge what would yield the best investment to learn on

Back when I got started on this "extreme cooling" addiction; I went with AMD to do my learning simply because overclocking AMD Black Edition chips is so easy; and because they scale so well with the cold stuff.
I picked up a used Gigabyte GA-790FXT-UD5P for something like $80 and threw some Phenoms at it (555 and 720 so far... I still have the 955 waiting to be frozen)...

I did a couple sessions on Dry Ice and then discovered Intel S775 stuff. Let me tell you one thing; freezing S775 stuff is the most fun I've had with benching since I got started. It is cheap as dirt; I bought a few C2D chips ~E6300, E6400, etc~ for about $30/$40 each, I bought an Asus P5QE motherboard for $50, I got some nice OCZ RAM (1150 @ 5-5-5) for $30 and I was off to the races. The only bad experience I have had with sub-zero benching was that it took me no more than five minutes to kill my recently acquired Rampage Extreme board and I never had a chance to bench my chips on that beast... And that "bad" experience was all due to my noobishness so I can't blame anyone but me on that one.
