Also ive allways been able to Super PI 32MB at 3Ghz with 1.5v. But it fails Primes after a few mins.

Bizarrely, mine at 2.7GHz won't do SuperPi 32M but seems happy running Prime95!

lower ** ram speed abit or relax the timing

Is that 2 sets of 2x512 TCCD you are running? What speed and 1T or 2T please?

oh no, just 2x512 running 1t command rate. I can see now my sig is a little confusing. :rolleyes:

Ok, i have just received my Opty 146 (CACJE 0546BPMW), i'm upgrading from my SktA setup and have negligible experience of o/clocking, as a first step i need a skt939 mobo plus a suitable method of cooling (air), i currently have an AGP graphics card (9800pro) but am willing to upgrade to PCI-E, i also have 1gig of PC3200 DDR (Non-dual channel).

Any recommendation would be appreciated.

CABYE 0540 (BurnIN working)

Well ive just stopped the burnin as i need to use the rig and it now boots into windows at 3Ghz at 1.39v (windows Reading)

I know for a fact before burnin it would have crashed at 1.4.25v into windows as i tried a few times.

Im still gona burnin at 1.4v tonight at 3Ghz as its certainly making a difference.

Ill keep the reults coming.

Ace! I really didnt think it was your ram! seen as it overclocks pretty well.
Glad you found out what your weak link was!!
Thats pretty much identical to what im getting! Its just windows is driving me mad! it will prime at 3ghz stock volts with both the blend memory intensive test and fft cpu test and it will sit there happy priming away hour after hour. Then the next time I run my pc windows will tell me the system recovered from a serious error (which it never had) or I get that blue screen. All this intensive stress testing it futile, it seems to me you have fully succeeded in overclocking your system only when windows finally becomes happy lol.

oh yeah, clint what are you using for board drivers?? I'm still running the drivers that came with the dfi board, ran a few bench marks like 3dmark2005 and I noticed my cpu score was only a little better than my 2gig winnie
In contrast its aquamark3 score completely and utterly obliterate my previous winnie and x800xtpe score. didnt think 90k was possible with a stock clocked 850xtpe

Yeah, turns out that the Infineon is holding me down @ 2.95 no matter what I do...I give it up to 1.55 volts and not a single mhz gained. (did turn out NOT Primestable @ 3ghz)
It is very obvious that this combo of CPU and MB is a very high performer but also very picky about RAM...

As for my drivers I use the drivers that came with the board:

Audio driver version 4.57 (WHQL)
Audio utility version 4.50
Ethernet NRM driver version 4.66 (WHQL)
Network management tools version 4.66
SMBus driver version 4.45 (WHQL) with updated uninstaller files
Installer version 4.60
Win2K IDE 2.7 driver version 4.79 (WHQL)
WinXP IDE 2.7 driver version 4.79 (WHQL)

Now I MUST order me some good sticks...

yeah, definity a flaky combo with the "wrong ram" and even with the cpu aside these dfi boards aint to keen on tccd chips(my ultra d was only happy running at low vdimm when flashed to 623) but then again when ppl get the sweet spot with a good set of tccd ram ddr600 is no probs! go figure lol

gskill even have an idiots guide to ddr600 for there pc4800 tccd sticks on dfi board sets...

what ram have you got your eye on then??

I'm looking at kits in the price and performance range similar to this ones:

OCZ GOLD GX XTC, DDR PC3200 2048MB Kit

Mushkin High Performance DDR 400 2048MB Kit

Living in Sweden so I have to grab it from Germany and get hitted by some 30 euro extra costs...

I'd edit out those competitor links as you may get a holiday when the dons get back from christmas dinner!

Have been reasoning back and forth about this "burning in" of the CPU..

After some reading about I decided to make use of my common sense and do the "burning in" in short cycles.
I run CPU Burn-in for 30m min (43 degrees C), turn the comp off and let it cool down (1 hour) and has repeted the procedure a few times and already I have gained 30mhz stable.

Using AS5 so I guess it is sinking in nicely

I think I've finally hit the limit of my chip and/or board.

I've been continuing to test over the past few days and it seems to be maxing out at 3.4Ghz. I'm not sure if this is down the the motherboard though, as I can't test on lower multis as it won't boot for some reason.

In any case, the chip is not scaling with volts over 1.75v, with 1.75v and 1.8v both giving the same clocks.

Like I say though, this may be down to the motherboard hitting its HTT limit.

Heh, not bad..3.4Ghz..

Maybe time to grab one of those DFI boards...mine hits 400Mhz easily

This is using an Ultra-D. I suppose it's only a possiblity I'm hitting the HTT limit, as it's much more likely that it's the CPU. Generally they don't scale too well past 1.75v anyway.

Just waiting on my new graphics card to get some 3d benching done with it.

Heh, well...1.75 volts..

Gonna be nice to see what you get scorewise

After some fiddling finally I managed to hit 3.1Ghz

Will not stay there though, to much voltage for me...but fun anyway!

Good Clock mate.
I have exactly the same cpu, whats your msn addy?

Thanks, Sam

4Qman · 26 Dec 2005 at 00:08

Clint,

So you have it stable at 3.1Ghz, i take it this is as you changed the ram. Im sure
the burnin has helped a lot. Im running my CABYE 0540 at 2.95Ghz Prime Stable 8Hrs+ at 1.525v.

It must be my ram failing prime as i can hit 1.7v and it will fail at 3Ghz,.

2.95Ghz is fine as im idle at 25oC and dont go above 34oC on load.

Cracking clock, you've got an amazing chip there.

Crank up the voltage I say, you've still got plenty of headroom.

Actually I have the Kingston suckers back in, did try a "burn-in" theory that did pay off...problem is it reverted as soon as the cpu got cold.
I will repeat it today and se what it gets me.

@ hyper7racer..sorry, no have...but feel free to ask here

@ Kesnel..hehe, up to the 1.7-ish huh? (I'm to much of a chicken for that)
