Cheapest ship to hit 2.5ghz?

[DeathONator]

I'm thinking about upgrading now, and would like to know what's the cheapest chip I can be pretty sure will hit 2.5ghz or close? And who has 'em guranteed (or almost sure I will get the right stepping).

I have pretty good watercooling. Check sig for temps and stuff.

Lol, I don't mean ship, chip of course...

[Brunt]

the 1700+ I had 2.4ghz Stable with air..I am sure ya could get 2.5 with water..and I think I was limited to 2.4 due to my pc2700 RAM.

[DeathONator]

Where did you get your's and what stepping?

[treepop]

go hit up a FRYS and get the 1800+! awsome and cheap and fo sho gunna hit 2.4...well not fo sho.....but preaty good chance and hey if not 15 unconditional return ;)

[cherryp00t]

the excalibur 1700+ are still doing quite well you might wanna chekc out those out too

[Aihyah]

if you consider the included m/b, the 1800 retail cpu frys deal for sure.

Sorry no fry's here. :(

Luck of the draw plays a major part in 2.5 GHz, it's a myth that 2.5 GHz is "guaranteed" with anything.

2.3x is what they do on average. (My 2100+ is 2280)
2.4x is cause for celebration.
2.5x is a small miracle.

[dreammmatt]

indeed - - my 1700+ (on air) is 100% stable at 2.3GHz (1.8vCore), 75% stable at 2.4 (1.825vCore) and doesnt even boot at 2.5GHz - - i know for a fact that it would if i volt mod the mobo.

[c627627]

Heh, what does 75% stable mean?

Actually C... It's mainly voltage, not luck. Even bad chips will do decently with enough voltage.
I've got a JIUHB 1700+ around 2300mhz cause I like my voltage low (1.7v) I push it to 2.0v and I break 2500 without much effort (More effort than it took in winter though.) I'd wager around 2.3v I could hit 2650ish.

If you're willing to put 2.0v through it, I'd say a 2100+ or 2500+ is almost a sure thing for 2500mhz. 1700+ DLT3C's dont like high volts from what I remember hearing, so that'll be more luck-dependant.

Anyone remember what the amperage difference is on DUT3C and DLT3C 1700+'s?

The DL's are 1.5v stock, and the DU's are 1.6v stock.

those are voltages, not amps...

[Dr. Possum]

Oops, misread the question...sorry.

I've got to stop thinking 1.8x V is what we're talking about by default.

Does anyone have any info what estimated life expectancy is when you approach 2.x V and keep it permanently?

[gamer004]

i think you lose about 2 years on the 10 life excpentancy

[Illah]

2v on a 1.5v chip is a 33% overvolt, that's more than 2 years off.

The general rule of thumb that I go by is this:

10% is essentially harmless (1.65v)
20% is pushing it (1.8v)
30% is crazy (1.95v)

Once you get to that zone you can, depending on your luck (or should I say anti-luck?), experience overclock deterioration. In other words, it might stay stable for a month, then it starts acting up, then you need more vCore, etc... It's the sign of a sinking ship (pun intended).

Then again if it's a 1700+ you're talking about, that IS only $50. If all goes well it'll last 6-12 months and you'll upgrade before it burns out. Then again, if you're fifteen $50 might be a bit harder to come by :)

yeah I can reach 2.1vcore....that doesn't mean I will......I normally like to keep mine at at most at 1.8vcore in bios.....which as we almost all know on the abit mobos undervolts to 1.74 or so.....so I think I am in the realm of a ok :D

[altec]

I managed to hit 2.64Ghz with my 1700 at 2.1v, 45C, and then I killed my Abit by accident.....:(

With all that's been said, bear in mind that although you're pretty much guaranteed to hit 2.5ghz with any of the better T-Breds these days, you're not going to be able to run it with stability for prolonged periods of time. Mine is easily stable at 2.5ghz+ with 1.95v but I sure wouldn't run it like this for any longer than a few hours. There have been plenty of reports of pretty quick decreasing of overclockability after about a month of overvolting by over 30%.
