Well havnt posted for a while, been real busy, but ive had a little time to play with the 165 VPMW tht Absolute_0 sent me and i can say it is looking good

:)

After some initial teething problems (it was crapping out at the same place as my 170 UPMW) i think i may have a chance of getting prime95 stable at 3Ghz. Ive got the CPU naked and using 1.55v (CPU-Z, real vCore probably closer to 1.6v) and have been priming for 20 minutes. Load temps are hitting 42-44C, this is with my watercooling, fans always running at 5v (for burning in process i think im going to increase fanspeed, just to bring temps down a little).

I dont think i will be able to hold this overclock in the summer though, as the volts seem to be a little too high for when the ambient temps get into the 40's. Hopefully a new mthbrd will give me some headroom with regards to vCore, im keeping my fingers crossed tht the RX520 will provide this. Will update with pics when i get some prime completed.

Thanks to Absolute_0 for hooking me up with a great chip, looks like its time for my 0550UPMW to meet eBay, heheehhee

:p:

Hehe, well...that depends on how you do it;)

Done right it's still safer mounting the XP-120 in my opinion.:slap:

For best performance, you DO want to compensate for the torquing by compensating w/ support from above or below, whichever is easier.

Only thing about going IHSless is fact that core is slightly convex, so final mounting adjustments need to be done while looking @ temps in bios (or you can lap your core to flatten it like I do :eek: :D )

Lastly, you should lap whichever sink you use (If you haven't already) since I've had both and they were BOTH notably concave, bad match for bare or IHS. In fact if you haven't done that, try it first, since you can usually drive a truck though the machine marks on the bases... (Gain back a degree or 2 there :D)

Hmm, what do you think I can use to give support from below? Electrical tape on the chip?

I think I'll probably do this today, with results tonight or tomorrow. A guy on EOCF showed me his X2 4400 and FX57 running naked, vertically with a big typhoon and NO support at all, but I'd rather be safe.

edit: OK, I searched some of your posts and I will definetly use your idea of epoxying the h thing. I'm still looking for something to protect it though :slapass: I'm so damn impatient with this stuff though, I'll probably end up not using anything.

I doubt my reported temps will even get lowered at all, considering they're reported WAY wrong.. it's pretty much always between 38-42C, no matter what. It's 38 at 1.300 and 1.350, it's 40 right now at 1.400 and it goes to 42 at 1.45.. yeah right.

You can go much further than that! Try 2.9, if it fails back down to 2.8

Repo - Think leverage

After you mount it, push straight UP SLOWLY / GENTLY on the fan while watching bios temps, you may notice that the temps go down by a degree or 2.

Then you just have to figure out how to do the same thing WITHOUT THE FINGER :grr: :D Either from above (lifting) or below (like a jack).

Based on the 2 I have, 2.7-2.75Ghz on Default (Check w/ DMM, since most boards overvolt ) 2.8-2.85 w/ .025 more, then it starts climbing. I'm @ 2.9 on both machines w/ 1.4 - 1.425 vcore (real/dmm) :D

Are you talking about mounting it while in a vertical position? Because that's just crazy :eek: I just cut the IHS off, took 1 minute and everything went well. (besides a bent pin, nothing a small flat screwdriver couldn't fix :) ) Now I'm waiting for the epoxy on the BT to set (thanks for the tip!) I hope I don't crack the core
03-08-2006, 02:22 PM
mad mikee

After You Mount It :doh:

Mount w/ board/case horizontal.
Then get best temp like that, per my methods.
THEN put back in final position and gently nudge whole assembly up @ the fan while watching the temps.

You are then supporting the HSF @ TWO points, the board mounting and the fan.
Show me a pic of your setup, then I can describe in more relevent terms :fact:

I know what you mean. I'd get a pic anyway but I don't have a digital camera

I will be running the whole thing horizontal for a while anyway, I'm too damn lazy to stand it up. Plus I change out RAM a lot these days, so I don't even use a side panel. Thanks for your help, I will update once this damn epoxy sets :slapass:

edit: :mad: First mount, temps were the same, I let prime run for a minute and remounted. Second mount, temps were ~1C better, but core 0 failed in 2 minutes where it usually lasts ~1 hour.. remounted again, this time core 1 fails in a few seconds where it's usually 100% stable. :( About to do my 4th mount, I'm hoping the issue is because part of the die didn't have any thermal paste on it when I removed the HSF.. I will be pissed if I ruin this CPU

edit2: remounted again, this time spreading the AS5 evenly to make sure there were no gaps, and I also put electrical tape over the SMD packs. Not so much to prevent the cooler from touching them, but to make mounting easier (with just the naked core, the cooler would shake all over the place when trying to screw it down). Temps seem to have gone down a degree or two vs. previous method (Actually they still hit 40 supposedly but it jumps down to 39 more often. IMO the range from 38-40 is actually like an 8-10 degree C range of temps, as this sensor sucks). Well both prime's are on test 3 in prime now, and I'm just glad I haven't fuxxored my chip completely :woot: for me!

So if you take off your IHS, you MUST 100% spread the thermal paste evenly, or you could have gaps causing just certain part of the core to overheat!

edit3: before, core 0 failed on test 3 in prime.. went to remount again, knocked the chipset cooler off so I had to redo that.. now temps on it are ~1C worse :mad: BUT I finally got a perfect mount, temps are 38C and go down to 37 every once in a while. And prime is now on the 7th test on both cores :woot: These things are uber picky on how you mount them.. :stick: more hassle then it's worth IMO.

where have goood water cooling stepping 170's come out of recently. i always hear good steppings of all cpu's come from monarch, id get from them just need clarification
03-08-2006, 08:21 PM

I finally got my PWM IC temps down by mounting a PCI slot dual fan cooling card perpindicular to the motherboard on the side closest to my harddrives. (looks a little ghetto but so what) Max PWM IC temp is now 44C instead of 59-60C.

However I am having the strangest problem... I can dual core prime stable for all night long at 2.8Ghz, 1.35V BIOS, max CPU temp 40C.

But to boot into windows at 3.0Ghz stable I need 1.45V BIOS. Everything is fine until I try to dual prime then temps shoot up very very fast on CPU to 49-50C then core 1 always quits :stick:

So do you think it will work if I get watercooling?? I would hate to buy a watercooling setup and then it just does the same thing. 1.45V is not that extreme is it? Seems like other people here are doing like 1.55V on these
CCB1E 0550VPMWs no problem. Don't know why mine is so picky :(
03-08-2006, 08:37 PM

watercooling would definitely help, air doesn't hold the load down well enough on these thhings. They get too hot and fail, and your only option is more volts, which exacerbates the problem. These VPMWs want water.

Definetly, lowering my CPU temp 1 degree looks like it's gonna give me at least an extra 18-27MHz

Any info on 165s 0551 WPMW? Or anyone has a 06 DC Opteron? I've seen 146, 144, etc but can't remember seeing a single 165/170/175 etc...

I'm looking for a 165, maybe 170 that makes 2700 on stock, as the summer is coming really fast here! :D

I just picked up 2 165's with a DFI motherboard.
I am a bit perplexed on the memory settings.

I hit a wall around 290 with my mushkin, not sure it its my cpu or my mem thats carpping out. I was still at 1:1. Are there any settings/timing that needs to be adjusted to reach the 2.8 range, or is it really up the quality of the ram?
03-09-2006, 12:49 PM

put it at 166 or 180 divider and see if it will push

Okay I tried running at X3 and lowering my dividers to see if I could establish my ram limits. I was at 325 and I decided that was enough.

I swapped chips to test and see if I could find a higher default voltage while I was at it, the second chip (0546) let me in windows at 2.52 with default while the (0550) crapped out at around 2.4.

However on either of these chips, I cannot seen past 2.7Ghz at any rate. But I'm not convinced that its the chips though, I'm thinking more of some settings to accomodate the opterons running at higher HTT's or something.

Not very sure on these motherboard settings though. I was pretty confident with memory timings etc. until I loaded this up. :slobber:

I will try the 166/180 dividers in a bit and post my results

Alight, I tried the lower dividers and looser timings and no go. at around 2.7 both chips crap out no matter how much voltage I feed 'em. I quit trying at 1.5v

Any other ideas?
03-09-2006, 04:02 PM

Okay, I don't mean to spam the thread but...
I figured out that the main cause of my poor clocks is heat.

First off the DFI thermal sensor is complete crap.
Secondly the stock HSF with the 165 is okay but since its running off the DFI thermal controller it was not removing much heat.

I'l now dual priming at 2.5 on stock volts.
I guess a water cooling setup would be a good investement.

Is that on air or h20?

This is where I'm at right now with air cooling by BT.

At 2.75 with the same voltage core 0 fails instantly. I'm afraid this chips overclock may suffer because of one weak core. :(

2.7 on stock volts still ain't bad. We all have high expectations for VPMWs because some of them are so insane. I have tested out another after my first one in the sig, and it just can't compare.

MeatFrog, you are quite welcome, i hope it gets up higher! Remember these things are very temp sensitive, but you're getting good temps on your BT.

I need to wait till at least tomorrow as I hope to remove my DFI chipset HSF and use an evercool copper HSF...just not happy with temps even with AS ceramique I used on the DFI HSF fan

BTW..another very nice OC..I would be very happy at 1.4v(although I assume this is likely 1.43v) and 2850

MY HSF is a SI 120/Nexus fan..so I know 3.0 ghz will be out of the question but I sure hope for 2800 at lower vcore than my current 170 as FL are pain in the ass

Says 1.42 in bios, i go by windows. 2.85 with 1.4v isn't bad. Keep in mind it's loading at 41c. Apparently i get some of the hottest chips.

03-09-2006, 05:16 PM

Loading at 41C..I assume under water is great..I load 48/49C under air with 1.5v

I prefer the bios value since the DFI overvolts under load and I prefer to stay at 1.5v idle or about 1.53v under load

still a great chip I hope I do as well

watercooling in my sig, don't do air anymore :P
I spent a month F*CKING around with nothing more than a stock heatsink. I've had enough air.

My watercooling isn't that great, an old pump and an old waterblock lol.
I get the following load temps
1.31v 38c
1.4v 40c
1.45v 43c
1.488v 44c

Although some people are matching my temps on air, or in some cases i've seen loading at 40c with 1.488v. So apparently my watercooling isn't very good. I've remounted 5 times and this is as good as it's gonna get ;).

neal, 49c load with 1.5v is pretty good for air i think. I load past 45c with 1.5v on water.
03-09-2006, 05:44 PM

This on a 170 0546 xpmw which by some reports has lower temps???
03-09-2006, 05:48 PM
Absolute_0

Makes sense. This is gonna seem counter intuitive... but from my experience, the best clocking chips run the hottest. I think it's because the best clocking chips are all the new memory controllers, and although the new memory controllers are all coldbugged, they do seem to clock better on air/water even if they run a degree hotter.
03-09-2006, 05:55 PM

Well here are my results.

165 0550 XPMW @ 2.4 stock volts
165 0550 XPMW @ 2.5 1.4v
165 0550 XPMW @ 2.52 1.45v
165 0550 XPMW @ 2.58 1.5v
165 0550 XPMW @ 2.6... NFG

165 0546 SPMW @ 2.42 stock volts
165 0546 SPMW @ 2.5 1.425 volts
165 0546 SPMW @ 2.6 1.475 volts - Dual priming
165 0546 SPMW @ 2.7 1.5 volts... Core 1 failed 6 mins, dual prime

I honestly thought the 0550 XPMW would be a better chip! it is much more recent and the 0546 SPMW is not very common. However despite its modest clocks, it does seem stable and perhaps with a little water I can get 2.7 out of it.

Im using a DFI Ultra-D with 2GB of Mushkin XS4000 ram. I am satisfied with 2.6 stable since its in the FX60 range which is way more than I bargained for :)

Very interesting point

I really believe my 170 0546 xpmw does not have a good memory controller

My Crucial Valueram(5G chips not binned ballistix) ran @250mhz @2.8v 3-3-3-7-1t-8/2 drive/data strength on a Venice 3200@2750
but the opty 170 can only do 225 3-3-3-10-1t-6/1

I think it's more that better clocking chips draw more power.. thus run hotter. Also LDBHE isn't a very new mem controller, and alot of the new 06 X2's are doing pretty good with the LDBHE steppings
03-09-2006, 06:21 PM
Absolute_0

How do better clocking chips draw more power? I'm saying that at the same speeds/volts/cooling, the better clocking chips run a degree or two hotter than the others. From my experience anyway. The best are always hotter.

LDBHE is an exception, that's why the new X2s are getting a lot of attention.

Why does that not make sense? They draw more amperage, so they clock better, and run hotter. That is just a guess, but you can't write it off as wrong :confused: But that could be the reason

If 1.46volt on air (in win I presume) dual load I would say you have some 10C
higher temp in reality...44C is just not possible.

You have to restart the program, it reads speed on load. It's not like CPUZ, WCPUID or Crystal.

I'm much happier with this CPU now that I've removed the IHS.. it got me absolutely nothing but a few more hours of prime stable at all speeds with 1.4v, but nothing over my old speeds are 100%. It did help at higher voltages though, I've now got 3 1/2hours prime stable at 2799 with 1.425 in BIOS. And that's good enough for me.. until I get my water setup

Yes, I think the stock HSF is pretty decent as well. The clip system is a bit on the flimsy side but it has potential. I am thinking of throwing on a 120mm fan with a shroud on it to see if I can raise the efficiency and lower the noise rates.

I also found out that the DFI was not running in dual channel mode. Turns out the yellow and orange mem slots are color coded for a reason (mem timings).

I've been experimenting with vcores and different settings since last night, I wanted to ask if anyone had any suggestions for whats acceptable for vcore?
I'm at 1.5. but CPUZ says 1.472 though :cool:

Well just got my Opteron 170 CCBWE 0550 UPMW and I am currently running 3000Mhz x 2 @ 1.48v. Only primed for a little over an hour, because I am off to try some BF2 and run a couple of benches at this speed. I hope to get 3100x2 stable as my Opty 148 can run 3240Mhz rock solid 24/7.

FlyBoyGeo- I can't see your temps, what are you seeing idle/under load? PWMIC?

Look in the lower right hand corner, mbm5 i think, is showing +7c load.
03-10-2006, 02:42 PM
FlyBoyGeo

For some reason when I took a picture with Snagit, it would not show the temps. The PWMIC around 38-42C and chipset temps were around 46-49C. The idle cpu temp is about -18C and loaded +7-9C.

>>> These Optys run hot. <<<

I have been testing all day since my last post at 2x 3100Mhz 1.53v. Both cores were prime stable over an hour, 3DMark05, 06 and 01 benched fine. I played BF2 for an hour with no problems, burn a couple DVDs, winRAR'd a ton, with no hickups yet....

Ill keep you posted :)

Just arrived- testing on stock cooling until I put it under water (storm) over the weekend.

CCB1E 0550VPMW Seems good for 2.8 @ 1.4v- haven't tried higher clocks. Primed for 1 hour.

I'm surprised at the high load temps! :mad: Maybe a bad IHS. I'm not sure I want to remove it.

EDIT: My Chipset temps have been that high since the day my board arrived. I'm guessing bad mount. I'll reseat it with AS5 soon.

Very nice :) And your temps look about right for this CPU. I used to run 2772@1.4v in BIOS (until I cranked up the volts a bit). Temps were 40C with the best aircooling there is, and now they're 38C with a naked chip and the best air cooling there is. I just bought a nice water setup, we'll see how it does under that :D

PS I don't know why everyone goes by the sensor readings for their voltages, if you have a regular nF4 DfI board, volts are exactly what you set in the BIOS, +.03v under load. With 1.4v, it reports 1.372, actual is 1.401 idle and 1.431 load.
03-10-2006, 07:43 PM

The highest I can get it 2.6 @ 1.525v on my 165.
If I lower the core volts, it cannot dual prime. at 1.525 it is okay for several hours. I wanted to ask if anyone had some tips on possiblyt lowering the voltages or on how I can find out exacly what could be holding me back?

U be better off starting a new thread in the appropriate part of the forum. The reason i say this is because your question is not a simple one to answer. After starting the thread i suggest you simply edit your post here, adding a link to the thread you started in the correct section.

Some of the things u need to consider are, budget? ready made kit? DIY WC? Design?

Here is where I am at with the CPU absolute sent me

http://img84.imageshack.us/img84/233...3000mhz1yq.gif

This is (as all my systems are run) a closed case setup, exactly as things are in my sig (i.e. fans at 5v). I dont think tht this ovrclk will stand the test of the summer which is coming. The voltage reads 1.58v in windows, but is actually 1.65 under load when reading with my DMM. For the voltage i am using i think the temps are pretty good. This is IHS-less and slightly lapped core. Im hoping i can get the temps to drop a degree or 2 after the AS5 has had time to settle. Whilst priming i have been working in illustrator and photoshop as i find it better to be running other apps when priming as this is guranteed to bring down prime95 alot faster ;)

I will edit post when it fails, and im sure it will fail, hehehee

-EDIT-

Oh ambient temps are arnd 23C, in the case is probabaly in the 30's

- EDIT x 2 -

Well core0 failed at 2hrs (its always core0, LOL)

Think im going to leave core0 loaded with CPU- Burn-in, hopefully i can break her in, hehehee

I got a question i would like some opinions on, at the settings im running i had to drop the HTT multi to 2x, raising the LDT voltgae does not help stabalise at higher HTT speeds, so my HTT bus speed is 668mhz. Is this a deficiency in the CPU or mthbrd? Id like to think its the mobo which is having problems handling the HTT bus speed....

With that CPU i couldn't get past 2.93-ish Ghz at all, even with clockgen, without using 2x LDT multiplier. I am pretty sure that i mentioned it to you, because it had me stumped for a few minutes myself.

Anyway man, 165 @ 3Ghz stable on water is pretty sick :toast:
i wouldn't even worry about only 2 hours prime, i rarely test for that long anyway. I'll bet if ambient temps go down 1 degree it will run many hours more.

And 23c ambients, damn. It is record cold here in Santa Cruz, like 3c outside, got some snow-ish hail. Closest thing to snow i've ever seen in Santa Cruz in my life, record cold levels.

New Member with an DFi Expert MB/Opteron 170 and Questions

I want to thank everyone for the wealth of info that has been posted on this site, and hope to continue learning from you. This is my first serious attempt at building an overclocked system.

I have been building up an AMD Opteron dual core system based on an Opteron 170 processor, and have found some of my results to be quite different than expected.

I am getting better overclocks with low voltages than with what voltages are often used here. But if I up Vcore to the 1.4-1.45 V level, I am only stable to 2550 MHz range, and CPU temps rapidly hit 49-50 C (using Smart Guardian). I suspected a poorly seated CPU or a bad job of applying the AS5 was to blame, but redoing it (with a very thin layer) made no difference.

My Opteron 170 seems to really hate higher temps, with anything above a 46 C reading in Smart Guardian causing errors. It wasn't until I moved everything into my new Silverstone Temjin T07S case (much better cooling than my old Antec Sonata) and dropped my Vcore that my OC attempts met any real success.

I ran AMD MaxTcase yesterday, and it told me my max Tcase temp is 53 C.
I have been able to run dual Prime 95 at 18 hr + stability (I stopped it then, no failure) with CPU and PMW temps of 41-42 C. My chipset temp is only 38 C, perhaps due to my running a Zalman chipset heatsink. (all temps off of Smart Guardian).

My opteron 170 seems quite efficient, giving me 2700 MHz for only 1.350 Vcore, but I was hoping to reach a stable 2800 MHz so I could maximize my Mushkin XP4000 Redline RAM (set on an 11 divider). This RAM is stable to 257 MHz with current settings.

I noticed my Vantec Stealth's 470 W PSU's voltages were starting to fluctuate (consistent undervoltage) at my 2700 MHz overclock, so I am replacing it this week with a OCZ Powerstream 600W PSU before going further. I hope the extra power and stability of this PSU will allow further OC improvements on air.

I have several questions:

1)Is my particular version of the Opteron 170 (CCBWE 550 UPMW) more suitable for a water cooled system because of its apparent temperature sensitivity?

2) Should I "pop the lid" off of my processor, and if so, what are the likely benefits/potential risks? Keep in mine I am using a Zalman CNPS9500LED heatsink, and it is not particullarly light.

3)If I eventually go with a water cooled setup, do you think my Opteron 170processor will handle more volts and provide better overclocks, or am I better off going with an Opteron 175?

Any input or suggestions on how to proceed will be greatly appreciated.
03-11-2006, 12:42 PM
Clint

Stick with your 170'er, the 175'er will not perform much or any better.
The OCZ will definately be an factor when chasing higher clocks.
Opteron 170 seems to have a "magic" temp limit of 44-45C to stay under, it's more a matter of keeping the temps down than feeding voltage.
It sounds like money is not a major concern for you, grab a better watercooling kit and you will most definately hit 3GHz on not too high volts.:)

Looks like the chip has a LOT of potential

A note though, with dual cores you aren't really stressing it unless you run 2 super pis simultaneously.

Take the SP folder, make a copy of it, open up both SP executables, go into task manager and assign each one to a specific core, and then run them simultaneously for the full dual core effect.

I have alsost just received my 0550VPMW from flickerdown (thanks), and I must say I am quite satisfied so far. Fired it up to 2.8GHz at once with vcore at auto.
I have run some test, SuperPI, 3dmark01/03/05/06 and seems stable at 2.8GHz.

Have too say these 0550's are quite hot chips, I have 38C as idle temp on CPU, with "low-end" WC. And it reaches about 47-48 on 100% load.
The 3GHz SS is not stable at all couldn't even dual superpi 1MB, hope to tweak it stable..

Yeah dudes, if you've got 3 Ghz dual core power, you should really be contributing it to Rosetta. Unless you literally game ALL day long.. those 3 Ghz cores are gonna go to waste without keeping them loaded!

What he said about burnin and testing

I could prime for hours, and then D2oL would hang the machine after a few hours.

The same settings for D2oL stable would hang the machine again after a few hours of R@H. So R@H is a great stability test as well as burnin tool. Work your Integer and FPU units and your memctlr all @ once!
I started MikeEpc chip @ 2.85 Ghz -> now 2.95 Ghz. Next week 3.0 Ghz, the OC gods willing :D.

Oh yes both chips sit @ 38-39c under load:
WC - PA160, mcp655, storms (G4 in the basement, G5 up here). MikeEpc (V2000) is in the WC gallery. Oppo(sition)Cruncher (V1000) will get some pics up soon.

Yes, u did mention it to me, but i didnt remember that when i dropped the HTT multi, LOL. Core0 has now passed prime95 Custom 8-4096 FFT's for over 14hrs @ 3Ghz, but running byitself. Ive just got out of bed and have fired core1 up to see when i will get a failure. If i can get passed a few hours with no failure than I am calling quite on the priming action and will be moving onto some gaming before finally saying if i have a 3Ghz duallie

:p:

I wonder if the CPU will clock further if i drop it to 1 x HTT multi, heheehee, maybe I should try it ;) all in all I am very happy with this chip, still not totally satisfied as I am greedy and wish a had one of those golden 170VPMW's

:D

Again i am seeing peeps post here how core0 is weaker than core1, this is how i have strengthened my core0. I have been running core0 by itself under load with CPU-Burn in for over 10hrs, then running prime95 straight after. When prime95 fails. I turn off the computer for a few hours, then start it up again, and then repeat the procedure. Once i get core0 stable for at least a few hours with prime95, I fire up core1 with prime95, but run core0 with CPU-Burn in, again for a number of hours. After that i try to run both cores together with dual prime.

I am this stage right now, yesterday when i posted i was doing my first real dual prime attempts, and core0 failed after 2hrs 45 min. So i fired up core0 by itself again, and it failed after 3hrs, I agian fired it up again, and it has been priming till this morning. I now have both core running in tandem.

Hope this helps

The date was wrong on my computer when I started SP2004, so i adjusted it while SP2004 was running, this made the duation jump!
This is actually a really nice way of cheating the SP2004! :banana:
