My WC Mobile Barton results. Disapointed

[mycotopian]

This is what I have been able to get out of my Mobile barton on my new water cooling setup. NEedless to say I am not doing cartwheels. My setup is a WW/MCP600/2-342/1.5" ID everything.

its actually hovering more around 20C above ambient lately

[graycat]

Not bad at all, you can almost match the performance of a stock FX-53 at this speed.

[Dragonprince]

Looks to me like your OC is excellent. The performance at those speeds is very very good for a 100 dollar chip. One thing I would tell you is your WC setup seems to have issues as im only @ 37-39c under full load on air cooling. You are 200 Mhz higher than me but we are both at 1.8v core so your WC should be doing better....which might get you more from the chip.

[spazzmattah]

With that voltage at that speed, that's very good. I'd say you got an above average chip. You see some 2.8-2.9 Ghz OC for the mobiles, but usually with really high voltages. Your chip probably could do higher with more voltage. But your temp is an issue right now.

[mycotopian]

should I add a second 2-342 heater core or maybe a dual pass one? Since the cpu is the only block in the loop I dont think I'll have flow issues. The HC has no fans and is not shrouded by the way. I am trying to keep this system as silent as possible.

[rivercom9]

For a water setup with a fanless core the temps are actually not that bad. Now if you were to put a quiet 120mm fan on that thing and with a shroud, you can look at maybe reducing the temps about 2-3C which can make a world of difference because some of the Mobiles really do not like a lot of heat specially when being OCed heavily and with a lot of voltage. Nice OC nonetheless. As far as adding another HC, it shouldnt affect the flow too much and I think it would benefit your setup. However I cannot give you an estimate on how much. Happy OCing dood. :D

2630mhz at 1.8v? With a silent system, and not alot of airflow over the core? I think that's kick arse. When I get my 2500-M (which was used), my goal is 2700mhz or more based on what the other guy got w/ air.

[Posidon42]

this is great seeing as my 2500+ mobile can't get more than 2.5ghz on water @ 1.95v and I had to cool the mosfets to get it stable that high. And this was using a 200cfm fan on the chevette heatercore. Granted my temps were a little better, but clock speeds aren't. Looks like you are doing ok to me.

He would beat a fx-53 at that speed. At 2500 Mhz http://bit-tech.net/review/309/3 the barton "almost match"

[mycotopian]

Update

I got some sweet NMC fans from Beerhunter and now my temps are way down. I dropped my fsb a little until I get the fans properly shrouded but still not bad at all for 1.775v and dead silent.

i had troubles with 2480 mhz, 2.0 volts and a bad WC set up. My temps loaded at 51 C(too hot for me). I coud lower my voltage, and lower the temps, but then I lost stability. Im going to try for 2.1 and 2600mhz when Im done with my WC setup. In other words, thats not bad at all

Good luck

[Hydr0 Styles]

Don't feel so bad, my mobile isn't stable at anything over 2.6, reguardless of voltage. It's like a wall. Pop in my friend's mobile, and I get to 2.8 no sweat.

I'd RMA my chip, but there's no reason to. It's not defective or anything, and it's not worth the trouble. 250x10 will suffice for a long time.

EDIT: About that bit-tech review... would a barton running 2.5, but a 250Mhz FSB x 10 multiplier perform higher?
I mean, probably not with the CPU only tests, since they are both at 2.5Ghz, but the overall system performance would be higher, right?

[mycotopian]

I never pushed it over 1.85 volts. You guys think I should step it up to 225 or so and keeping pushing the VCORE up until its stable? What VCORE should I stop at?

[Captain Newbie]

Awesome overclock.

Always keep in mind: There is such a thing as fast enough...

...but I'll let you know when I find it. :attn:

There is a formula somewhere for the % shortening of CPU lifespan for a corresponding % increase in Vcore. I would keep Bartons under 1.9 volts core, especially mobiles which are designed for lower voltages. Mind, since you're on water, you might be able to deal with 1.9-.95, but this is up to you. It's your computer.

Do run Prime95 frequently. This will tell you of any signs of impending trouble.

Hydro:

A higher front side bus will almost always increase performance more than a higher multiplier when the system RAM is run in sync. This is because your memory bandwidth will go up, rather than just the internal operational frequency of your CPU (as with multiplier). Higher FSB = Higher memory performance = Faster, to a point.

Cheers!

[mycotopian]

right now I am having trouble breaking 210 even with a 10x multiplier. any suggestions?

[Captain Newbie]

Seems that you have found the limit. :(

Time to start upping the multiplier...slowly.

If my case had good airflow (I need to add a fan) and the temps were good I would push 2.1v maybe more and wouldn't mind pushing 2.3v for a burn in.

:drool: :drool:

Disappointed???

Those results are spectacular! 2.6GHz at only 1.825v is amazing.

I didn't back down until 2.1v with my T-Bred, and I still made it only exactly as far as you.

Definitely agree. You're gonna want to try to break 230 ideally; should be no problem for your system.

[asdasd]

wow 1.5" ID tubing is freakin huge, i sure huge you meant 0.5". and i have to say whats there to be disappointed about? looks like a splended overclock to me

[mycotopian]

so what do I have to do to take it to the next level here? better northbridge/southbridge cooling ? heatsinks on my mosfets? I am willing to do slightly intrusive mods but I really dont want to risk my board.If it matters I am running the abits Bios 6a61BA1BC-18 from 7-24-03

[Quailane]

Makes me proud of my $36 (now) duron. ($41 new). It uses an aluminum sink with copper core with an 80mm fan modded to it with electrical tape and a styrafoam cup. It boots 2400Mhz with 1.7 volts, but the board needs to be more stable for me to go further.

A 2.6Ghz barton is better than most can get, but it is nothing spectacular. (That 5.2Ghz PIV at Tom's was).

[BeerHunter]

Durons are the best. I have no idea why more people don't buy them. If I were paying for my system I would.

yeah, but liquid nitrogen, im sure we could get a lot out of a mobile with some nitrogen

What about those Bios recomendations boys

Only reason I got it was that I couldn't afford anything else. :p
It would have been a stretch for me to afford the 1.6Ghz. :D

The bios shouldn't be affecting your overclock. You should just be happy with what you have at 2600Mhz. I've read about others on this forum who haven't been nearly as lucky.

[mata2974]

good overclock, dont worry be happy.........what else do you want!!!!

[makaka]

as i know abit read temp from socket(correct me if i am wrong)that s mean that diode temp should ~+10c (60 c is too high)
for the first picture
between nice overclock :)
