OMFG!!!! UPDATE!!!! I'm running P4 2.0GHz @ 3.2GHz, 1.6V on AIR!!! Have a better chip now!!!

:Q I can't believe this!!! I got my hands on six P4 2.0GHz OEM chips with the new C1 stepping and after popping the first one in my computer, I am running at 3.2GHz, 1.6V, 160MHz FSB!!!

*EDIT* Considering I don't have a motherboard with a PCI/AGP lock my hard drive got screwed up in the process, so I had to back down to 3GHz, 1.6V, 150MHz FSB *EDIT*

I ran the latest Prime95 Torture Test for 25 hours with NO PROBLEM!!! Wow, I had high expectations for this chip, but I had no clue that they would be really that great! I just with I had a different motherboard, so I could push it even further. And remember, this is ON AIR!!! And this is not some crazy-ass Delta fan running at 6000rpm, I have a Vantec Stealth fan at 2000rpm with Thermalright AX-478 heatsink. Temperature is hovering around 44C. What water-cooling could do, I cannot imagine. WOW, WOW, WOW!!! :Q 50% overclocking is back with a vengence! 😀

UPDATE!!! I have a chip that boots at 166MHz FSB at 3.32GHz, 1.525V!!! Even my chip that I am talking about in this post cannot do that :Q I'll update this thread with my endeavors :Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q Too bad I don't have a better motherboard to find out its limit as my ASUS P4S533 maxes out at 166MHz FSB, but I have an AOpen motherboard with SIS648 chipset with higher FSB, so I will try that. However, my 1.6GHz chip didn't overclock too well in this motherboard, so I don't hold my hopes high...
 
Rig was JUST updated...

I CAN'T increase the voltage. I mean I can, but as I said in my post, my HD got screwed up while running at 160MHz FSB. I don't want to risk loss of data, so I'll be running at 150MHz FSB until I get a motherboard with a PCI/AGP lock. BUT - the CPU was running FINE at 1.6V and 3.2GHz, God, I can't imagine what its limit is...
 
I have to admit... this is beyond a shadow of any doubt, the single most 'impressive' OC I have ever seen..... considering I have my C1 stepping 2.5 @ 3.0 @ 1.725 volts in a wind tunnel and can't go too much further... 😕

Why do you say this? When the 1.6A's were out it was not all that uncommon to get 2.4 out of them and that's 50% increase.

Just considering...:

1) the cooling Luk is using
2) the voltage (1.6v is crazy power...shit thats less power than Intel is going to used for Intel's factory 3.06 parts and I think the 2.8 parts
)
3) and it is a 1 GHZ OC impresses me greatly...

Great OC, but it depends on how you look at it.

My Celeron 533A had been running at 880 for just about forever (800 for the last month now, just to keep the PCI bus speed in spec). It has been on 24/7, running OGR in the background - 100% CPU utilization whenever it's on. Also, I've run it stably for several weeks at 920. It runs stably at 960 (on a different mobo, at least for about 4 hours stressed to the hilt).

533 @ 800 = 50% overclock
533 @ 880 = 65% overclock
533 @ 920 = 73% overclock
533 @ 960 = 80% overclock

All on air.

Hmmm, here is how I look @ it...: ITS A ONE FREAKIN' GHZ OC ON LESS THAN DEFAULT VOLTAGE WITH MARGINAL COOLING AND ROCK SOLID STABLILITY!!!!! .... /that is how I look @ it...
 
Not trying to argue, but don't you think it's a little early to deem it "rock solid stable"? It sounds like it got setup today, and that's hardly enough time to deem a system "rock solid stable" IMO. I guess everyone has different ideas of rock stable... 🙂


BTW - 1ghz overclocks were very common with the 1.6A's, I had one that would do 2.56ghz, 1.65v with a Alpha and a 21CFM Panaflo. I needed 1.7v to hit 2.6ghz and that was too high for me. 🙂
 
I bet you get 166fsb with 1.65-1.7v and that would very nice in a GB DCDDR mobo.....Going to sell any of them???😉

1.6@2.74ghz = 71% increase...not bad....

2.0@3.32ghz = 66% increase....


I need some c1 stepping chips!!!! I wonder if the 2.26ghz chip can get to that 3.2ghz at 1.6v for 189fsb or 378mhz ddr in a GB DCDDR mobo...Can you say 4500's in sandra!!!😉
 
Ok....I guess this just needs to be cleared up.....

1) A 1.6a to 2.6a OC with modest air cooling and low voltage is an EXOTIC and FABULOUS OC.....period.
2) A 2.0a to 3.0a OC with modest air cooling and low voltage is an EXOTIC and FABULOUS OC.....period.







IMHO 🙂

You and me both! I see three things in my near future...an Epox GB board, HT, and 3Ghz+ with a high FSB.


You know what would be really nice...a low multiplier C1 @ 200mhz FSB! From what I'm hearing, GB will only run a 1:1 FSB/Mem ratio. That will make the lower speed C1 chips very popular with us overclockers. 🙂
