WooHoo! cB0 C2-600@1008

[Newbie_Doo]

Finally!! I get to change my sig!

I rebuilt the watercooling system reservoir, adjusted the voltage and FSB and voila! I finally broke the 1Ghz Barrier!!

[Mr B]

Awesome, Newbie Doo!!!

Psyched for ya....Yet another C600 climbs to the top of Mount Gigahertz!! And a cB0, too. Good job!!

[Newbie_Doo]

I am starting to get that itch again...

Just how far WILL this chip go?? LOL

Alas, prudence dictates that I wait until the backup box is online before I start pushing any further. Also, I want to make sure that 1008 is 24/7 stable first. If so, this is a major leap for a chip that wouldn't go more than 810 under aircooling.

Now if only my replacement mobo would show up for box #2...

Mine is still on waiting list :( , but as soon as I learn more about vidpinging, and do it to my chip, I'll be there! :)

hey Newbie_Doo, what CV are you using?

[Newbie_Doo]

Hmmm...when playing Half-Life, I get lockups and then on reboot am getting registry errors. I am at 1.90 Volts, whaddyathink Brian...should I go to 1.95V or won't that solve it. Temp is at 26C core / 22C ambient. Is the registry error due to out of spec PCI (35 or 36Mhz), or chip instability?

[Super]

I've read an article once, and the guy had to set the CV to 1.95 in order to make his Celeron 2 600 cB0 stable at 1 gig.

[LutaWicasa]

Congrats! With the great cooling ya got going, don't be afraid to bump up the voltage. My 566 @ 1054 needs 2.0v and never over 38c. Have had it here for about a month or more and no probs. No reason at all to be leary of 1.90 or 1.95 :)

[Sempei]

WTG Newbie Doo! What MB are you using in that setup? Is it slot or socket? If it is slot, what sloket are you using? I ask this because I had a similar situation with my setup using an Abit sloket. It was stable at 927 but no amount of voltage (up to 2.1v) would make it completly stable at 1008. Prime95 would always fail. Switched to an MSI 6905 Master sloket and everything was stable including Prime95 and the voltage dropped to 1.9v. Just an idea.

[FrankMasterFlash]

Great job, thats faster than mine will go, and its a cC0. I'm jealous. I am having problems at 945@2v. I will probably go with a P3 next.

[Mr B]

Newbie Doo,

Man, ya gotta at least try....I understand that's a cB0 chip there (1.65v default), but like Luta said, those temps are nice and low....I really don't see 1.95v briefly being any problem.

IF it flies, burn it there (1.95v) and see if you can then get it stable at 1.9v...just watch them temps at 1.95v.

I'm rootin' for ya. 100% stability....good luck!!

Mr B

*update....missed the Q: about the PCI bus possibly causing the Reg errors....doubt it. I ran at the same FSB setting (112) for quite a while, and never encountered any problems like that. I think I was even FURTHER out of whack at 117 FSB, and didn't have those problems....*

[batboy]

Mr. B, actually C566 and C-600 cB0 chips have a default of 1.5v, however, they still will handle 1.9v no problem with good cooling. I say with watercooling, Newbie should have no problems even up to 2.0v. Bump that voltage up, Newbie. Stabilize and sweet talk that baby with more voltage. Caress it with cooling mods. She'll put out.

Wow, that's sort of making me get the itch again too. What about a new cD0 1 gig chip and watercooling... a super nice gaming rig if you slide in a new Hercules GF3 vid card. :)

[Mr B]

MAXIMUM PC had a review of the new GF3 in the Apr 01 issue...

My drool-stained keyboard now wants me to read future issues of this magazine in the bathroom, over a tile floor....=)

Can't wait for prices on these to come down!! Looks like a killer vid card.

This chip is absolutely rock-stable at 945Mhz, and has been for a while. I finally get it to run at 1008 and I get registry errors. I think that as long as the temps are OK, I can run higher voltage but I am leery of the 2.0V mark. I've got to try to get stability though...having tasted the 1Gig sweetness.

I think I may have found the registry error problem. Voltage made no difference to stability, but I was running my memory (256MB Crucial PC133 CAS2) at HCLK+33MHz and CAS2. This meant that I was running at 145MHz memory clock CAS2. I think this memory stick doesn't like that speed. Running it CAS3 didn't help, but dropping back to HCLK/CAS2 it seems to run OK.

I am going to abuse the system for a while and see if it remains stable at these settings.

Way to go Newbie_Doo! I'm jealous too. I'm stuck at 972Mhz and 2v. (need to update sig) I need to upgrade my HSF or go to water cooling. My CPU temps are are 7C above ambient (usually 24C room temp)at idle and average CPU full load temp is 43C but spikes sometimes to 48C. I tried burning in at 66Mhz FSB @2v but cannot wean the cpu from 2v @FSB 108 or above. Not stable above 108 FSB. You made your own water block eh? That is so neat. Have you posted pictures or a write up of how you did it?

I posted a pic a while back of the block, the write-up is a work in progress. Joe C tested the block for me and it performs equally to the new BeCooling block, which is slightly better than the DanderDen Maze block. Anyway, here is the block again:

[Phil]

I don't really think it's worth water cooling a celeron, at 1.01ghz you get about the same performance as a 800-850mhz p3, so for instance if you bought a 700mhz p3 and overclocked that to 933mhz and no more then that would likely cost less than a water cooling system and perform better

[Newbie_Doo]

...and if you climb the local mountain you haven't gotten very far from home either. It's the challenge of the journey as much as the destination, Phil, I thought you knew that. Yes, I could have done better with a P3-700, 750, 800, 850 etc. I happened to have HAD a C2-600 to work with. Frankly, for most of what I do, 945Mhz was just fine. Getting to 1008 was nice, that's all.

[LutaWicasa]

Hey Newbie_Doo, right on ma' man! Its like asking why peeps oc at all. BECAUSE I CAN :):):)

[Slake]

Thanks for re-posting the pic Newbie_Doo, That is one sweet piece of work. Your post inspired me to try for a little more FSB. I am looking forward to reading your article.

[Newbie_Doo]

Good news-Bad news:

Although changing the memory timing allowed the computer to run normally for most things including Folding and surfing and Photoshop simultaneously, I still get lockups during Half-Life which is both memory and CPU intensive. Ditto at 981. 945 is still rock solid during game play though, so all is not lost.

I am at 1.95V and am hesitating to go to 2.0V. I am not sure it will make a difference. Any suggestions Mr. B?

and if it's just pure clock speed you are after then a P4 wins everytime if you see what I'm getting at, I am just saying that I wouldn't go the expense of water cooling on a celeron, maybe on a tbird or a plamino (when it's out) as you will be getting a valuable return for your work

[Newbie_Doo]

Fair enough.

I built the watercooler as an intellectual excercise, not for the purpose of pushing a C2-600 to its limits. I had an idea for a waterblock design, and didn't have a watercooling system to try it out in. The watercooling system was a sidebar to the process of refining a waterblock design.

In fact, my system is louder now than aircooling ever was, more hassle to maintain, and causes me to worry at night when it is unattended. I have already had a cooling system failure (reservoir leak) that was not catastrophic, but I think the basic premise is truly the future of CPU cooling. As we push CPUs to ever greater heights, aircooling will become more limited in its ability to keep up with the leading edge of technology.

The nice thing about the system that I built is that it will work just fine on an Athlon system too. The poor overworked Celly will move down the chain to one of my kids, and the watercooling rig will sport a faster, meaner, hotter chip in the near future.

Anthony

[Phil]

In your situation I understand perfectly why you did it, it probabally didn't cost you that much money and you did it to see if you could, but the thing I guess I was getting at is when people peltier and water cool celerons using expensive comercial kits just for the mhz when they are only performing as well as an overclocked pentium 3 running with air cooling and costing much less, it's just that the mhz isn't as high (celerons being about as fast as p3's clocked 150-200mhz slower)

[Newbie_Doo]

I'm with you, Phil. For the cost of the watercooling rig and prototyping of the block (which was NOT cheap), I could have a very nice pair of Plextor 16x CD-RWs, a 5.1 surround setup w/spks, 60GB of storage and a DigitalDoc5!

Try it. If it works, burn it in at 2.0v for a bit, and see if you can back off to 1.95v at the same speed.

Either it will or it won't...only one way to find out....try.

Mr B

*update...thought I'd throw in an example....I've pretty well documented the bump in speed I got out of my C600 (1008 to 1053), but I attribute that mostly to a far superior hsf, and motherboard swap. It might have had something to do with running for a month at 112 FSB at a high vcore (burning in).

I have seen something with the P/// recently. I really needed higher vcores to get anywhere over 800 MHz. (1.95v @ 954 MHz now). I did some tinkering the other day...and had the chip out of the rig for one reason or another. I put everything back together, fired it up, set the FSB to 133 (800 for my 600E) and proceeded to re-instal WinME on a fresh hdd. No sweat.

Started having problems shortly after installing, though, and couldn't figure it out for a couple of hours. Turned out when I reset my cpu configuration in the BIOS, I had forgotten to reset the vcore above default !! I had never gotten this chip to do anything at 800 MHz at default before (1.65v).

I'd have to say there is something to be said for burning a chip in....might help you too...

Mr B

[Newbie_Doo]

I suppose since temperature isn't an issue, that upping the Vcore to 2.0V won't kill it.

I was discussing this issue with a friend and he thought that the vid card memory timings might be giving me trouble since the problems only show up when playing intense 3-D games. I have a Creative GeForce2-MX (I know, I bought it before I knew better) and I have the memory timings maxed. He suggested backing the vid card memory off to default and trying it. I'm going to give it a whirl tomorrow-had a long day at work and don't want to mess anything up tonight.
