Does more but ime limited by memory isues atm, has been upto 2.9Ghz, and ime positive it can do 3Ghz on the stock

"CAB2E 0548 EPAW"

[iMAX]

Update CAB2E 146 0540

vcore 1,4V 3G stable SP2004 4h with water



vcore 1,5V 3,06G stable SP2004 6h with ninja

my max 1M on stock cooler, this is in a pretty warm room (40C idle you can see)

[Pt1t]

146 0540 FPBW under watercooling (1.63v not needed , it was to test
optimisation with gto² @ stock voltage)

nice result i bought a opty 146 0540 FPBW today too , seams like overclok like my 148 0543 FPMW , tomorow i already have the 146 then i post results.

[RafaDel]

anyone in here have a msi neo4 platinum w/ a opty 148? cause i need some help. my opty can do 2.8ghz on stock volts using clockgen stable in windows. but when i set anything over 238 mhz it results in no posting. i can only manage 237 mhz for an overclock of 2.6 ghz. i know its not my rams either. my ocz gold edition can do 260 mhz fine.

I had this board a long time a go, remember this problem was related with initial bios versions.

Hi guys,

Well I got my OEM Opteron 146 the other day, worried as hell because I didnt know stepping but it was dirt cheap (like £105 instead of £150 retail) so im not too bothered.

Stepping
Cacje 0546 BPMW

Anyways im impressed so far, doing 2.9ghz 290x10, 1.54v (according to CPU-z/MBM).

Anyone know why CPU-z/MBM voltage so much lower than selected voltage in bios? (even bios shows it as being lower than what I select). It says 1.54 but I think its more like 1.5+

Dude, what is limiting me?? I have a cab2e 0540 FPMW. I had it stable 2.87gHz w/ 1.39 volts load temp 39*C(air) for 9 hours 10minutes on prime95(i stopped it myself).


Things that I have not touched since, are:
LDT: 1.30volts
chipset: 1.60volts
LDT/FSB freq. ratio: X 4.0
Dram: 2.8 volts
.....

Dram isn't really the limiting factor I would imagine...

But I can't get this stable above 2.90Ghz(10X multipliers). The highest I cranked the volts in the bios was 1.50volts, putting it at 2.93gHz, and it will fail prime after 20minutes or less even.

This is ridiculous because @ 2.87gHz, I was running stable w/1.39 on smartguardian and 1.425volts in the bios... I guess I can't judge it by that, but still, am I not stable because I need to crank up even more voltages on my cpu vid control????

help please!

[MrSlacker]

hey dudes, i am looking to get 148 to replace my 3700 sandy, can you recomend me some good steppings so i can see if my local shops have them before ordering online.

Change your HTT multiplier to 3x. Also, what are the load temps?

[turbox997]

Change your HTT multiplier to 3x. Also, what are the load temps?

Load temps are 39*C for 2.9Ghz and below... although it did get up to 41*C when it was at 2.94Ghz. Generally, load temps are looking ok.

HTT multiplier to 3x?!?!!?!!? you mean from (I'm currently on)10X=> 3X?? Or did you mean the ldt/fsb ratio(I'm currently on 4X)?

I'm assuming the second one of course, but I'll wait for response.

[Absolute_0]

2nd one.

[turbox997]

gotcha', gonna try for it now, thanks for the tip I'll let you know how it goes by posting here.


edit: I tried it, still no luck, maybe it's just my chip? I was able to boot and load fine up to 3020mhz's(could have taken it higher but just didn't), obviously though, I couldn't prime it at those speeds.

I wish I could prime this baby past 2.9ghz. Any other suggestions(as far as mobo settings go)?

[fraggy]

Im getting same sort of probs with my opty...

running at 2.87 1.52 vlts but cant seem to give it anymore... !!!

And my temps are odd... damn they can get hot... sitting at 38 @ moment BUT any sort of work and cpu is about 48 - 50

Nice avatar Absolute m8

You said load temps were 39C, now they are 49C? That's quite a difference. You are running proper dividers right.

[turbox997]

I'm the one who had 39*C load temps, fraggy gets up to 48-50 with any kind of work on the cpu.
Incase you got us mixed up, haha, both of us have plain sigs, i'll try and get an avatar that stands out more.


My highest temps ever were 43*C. And even then, it just blinked at that temp for a sec. Is it common for the cpu voltage to fluctuate during idle? Mine goes from 1.39voltage to 1.40 back and forth while idling, kind of troubles me.

Oh, sorry, you can revoke my license to post at 7:30 AM... just trying to get a few posts in before going to class lol.

Well your temps are good, don't look at what it jumps to, just the overall average. CPU voltage almost always flucuates, so don't worry too much abou t that. I get stuff like 1.392 - 1.408 all the time, just minor fluctuations aren't a big deal.

What is bad are big fluctuations (like i used to get on my MSI K8N Neo2 Plati). It would jump around by almost .3 volts... not good for an OC.

I don't feel like reading 178 pages... so can somebody tell me what a 165 CCBWE 0546 can do?

its a shame these beautys costs so much here in Portugal... about 365€...

so can somebody help a doubtful boy?

thank you!!

Fist of all you might want to look in the dual core opty thread---
http://www.xtremesystems.org/forums/...ad.php?t=77857

Just a quick search in that thread gave these results

It wont hurt the use the search function....

This is the single core Opty thread, there is a Dual Core opty thread right by this.

There are some good week 46s, i think people were saying good things about 0546 XPMW? I know i've also heard good things about 0547 TPMW and 0550 UPMW if you can find those.

And 365 E for a 165 is a terrible price, maybe you should have a friend in the states buy one and ship it to you.

[sway]

oh I'm sorry... I really thougt I was in the dual core thread...

thank you very much!!

[fraggy]

Hey Absolute,

Im running on a 166 divider..... my temps inside case case rise quite alot NOW the odd thing is i can idle at 38-39 BUT as soon as prime comes on and i mean with in a split second the cpu temp goes to 50..... ive had 54 sometimes....

As soon as i stop prime the temp drops just as quick as it went up !!!!

YET i can still touch the bottom of my waterblock ( its a round base block ) and i cant feel any heat really.......

Damn last water system i had on my old system would NEVER go above 37 even playing games ALL DAY
