*** Official Opteron 170 Ocing Thread ***

Sry to bring my noobness to your uber clocks fighting match :) but im trying to get mine up to a reasonable speed but it doesnt seem to like it. Currently I've got my 170 (CCBWE 0551UPMW) set at 220Mhz and 1.35 CPU Voltage (On my Asus A8N-Sli) temps are about 43c load with stock cooling. My RAM (Geil 1GB DC Value) is currently set to 1:1 but that seems fine since I allowed 2 passes of memtest and nothing came up but im doing some prime tests and im getting some errors, see pic below.



I thought of rasing my vcore more but I've read a lot of you have got your 170s up to 2.7Ghz on stock vcore so voltage shouldn't be my problem should it? I've done the normal fixed PCI to 33Mhz and PCIE to 100Mhz, CPU multipler is on 10x and the HT Multiplier is on 4x. I wondered if anyone could give me suggestions as I'm rather stumped.

ignore memtest, it's not a patch on prime95.

set your memory to run slower (not 1:1).
 
No not really - When If your aiming of a HTT for about 250 you will get an FSB of 750, a good speed tbh. The A8N-SLi's probably aren't super stable with 1000mhz FSBs.

That aside, you are going to want to slap a divider on that RAM. Because its value RAM it probably doesn't want to budge above 210mhz really. So put the 333 divider in the BIOS and that should get you running.

Give that a shot and don't worry about your vCore just yet. I think your problem will lie with you RAM.

Hope this helps.

Not sure it needed that voltage, it may have gone higher than 2.8Ghz, it seems that yours doesnt or you havent tried yet ?

well i have done stability tests up to 2.8 ghz and just upped the vcore a few notches to get it 2.8ghz prime stable.

I haven't tried for higher but I think i need some active cooling over the PWMIC as smart gaurdian shows it getting a bit hot.

Tbh I'm mega happy with 2.8ghz on the vcore its on but I imagine itwill need a lot more for just a 100mhz gain so it might not be worth it.

but I will try for 2.9ghz to see if this is the case.

If i find that 2.9 ghz does not need that much volts I might opt for a water rig as I would not be happy running 2.9ghz or even 3ghz 24/7 on air.
 
Hey guys, sorry to ask here as I have an X2 not an opti but anyway, I'll fire away seeing as it applies to both sets of people and this thread is quite active... I can get 2.6ghz 1.36v dual prime loaded 39C. Now to get 2.8ghz, I need roughly 1.51v which dual primes at 49-50C. Worth it or not? My water system probably needs a rebuild and that may be why the temp is so high....or perhaps it is just pumping out that much heat, either way....your thoughts please.

I think 1.5 v core on an x2 for 2.8ghz is fine IMO
and your temps even though on water are fine..

I ran an x2 3800 @ 2.6ghz which need 1.5 v fine for 6 months on air so water you will be fine.

keeping the chip below 60 c is the goal in most circumsatnces.


go for it. :)

Yeah, temps I'm fine with, as I know these dual cores really pump out heat when you up the vcore. Temps should be better with a new waterblock (need an overhaul anyway - end of the month). So I'll get an Apogee (so long as it actually is better than the G4 Storm) and redo my cooling.

So you reckon it's worth it? I'm scared!!! Had a very hairy moment when i couldn't boot with my previously stable 2.6ghz until I realised that was done with a previous BIOS and trying to reload the settings was crapping out the memory. I know what I'm doing, hell I even have a guide on o/c'ing but is the extra heat/volts worth it for dual FX57? Never before have I ever had a chip that would do 2.8ghz (3200+winnie - 2.6ghz, 3700+ SD - 2750mhz, X2 4400+ old one, 2500mhz, this new one 2800mhz). I think it's all down to my waterblock not coping with the heat output which is causing the high temps but anyway... I'll get this done at the weekend - other views are welcome too...

Yeah 1.5 v is fine.

TBH i know how you feel this is my first time at 2.8ghz with a dual core chip at such low volts.

my last opty 170 would only go 2.6 on 1.5 volts

I'm at 2.8ghz on 1.36 vcore and temps are fine(on air zalman 9500) but I have a feeling if I take it higher its gonna need more volts and the small 100mhz gain or dare I say it 200 mhz gain making dual 3ghz! will not be worth the extra cooling and stress.

but as you have water then keep the clock.As you say temps are fine so go for it.

EDIT: I updated my bios 2 days ago made a raptor raid 0 array of an image and low and behold corupt windows! :eek:

I dont save any data to system drive anyway but now after a bios flash and new reinstall i'm, 12 hrs prime stable at 2.8ghz.

should have just reinstalled windows on thenew raid 0 array rathher than trying to be clever bringing an imgae over but you live an learn :D

The Swiftech Apogee is not better than the Storm.....just cheaper for 'close to' Storm performance.

Swiftech claim it is...oh well, I'll get the Storm then...I always wanted that in the first place. So the Apogee is more like an MCW6000 series...

Anyway, sorry for bringing the thread off topic

/resume Opteron clocking.

One question, King_Boru in another thread said the opti's use their L2 cache differently to an X2, is this true? I think it may be for the socket 940's but not for the 939 version. If so, is an overclocked opteron at the same speed as an overclocked X2 actually faster I wonder?
 
Just started with a new 170 CCBWE 0546XPMW. Gets to 2700 @ 1.45v without errors. Cycled s&m for a couple of hours, idles at 27C maxed at 41.7C. I keep thinking to get another cooler, but this Hyper 6 seems to do ok. Now to see how stable it is in some 3d benchies.

I'm starting to think that my motherboard is holdng me back (DFI NF4 Ultra-D)
With both my current opty 170 and my old Winnie I couldn't get past much past 270HTT. That was with two different memory, some TCCD @ 1:1 and a 2GB kit using dividers.

The thing that really makes me believe this now is that I can run my Opty at 270x10 but not 300x9
Click to expand...

My ultra D is exactly the opposite - it hates x10 multi but loves x9 (even past 300HTT) currently on 3/4 divider though for my 2Gb set


Now that my 1mb bb is working (finally) in my new flat I will d/l Prime and do some screenies for Big Wayne -and everyone else - to prove stability on my Opty 170 at 2.75Ghz with stock cooling and 1.39v (well bios is set to 1.42v but all software is telling me 1.39v)
 
Why do X2's need more voltage than the Opti's? Mines completely stable at 2.75Ghz but needs 1.6+ to keep it happy (1 core being weaker than the other). My temps are fine, it never goes over 42c@load and idles@32c (and that's with 2x6800GT's in the loop also)

Any ideas?

Yes you where right it was definatly my ram i set all the ram stuff back to default including the timings, ive got the cpu running at 240Mhz and so far everything is stable. :) Will try 250Mhz after prime has had a few hours to run :D
