Overclocking 6164HE Opteron's?

Hello all,

I'm new to [H] atm, but have browsed around a few Overclocking communities and i've heard tell you guys are the foremost experts on the G34 socket and folding, so i was wondering if you guys could help me...

I've been offered 4x 6164HE (1.7ghz/12c), and i was curious as to how these guys might overclock in a Supermicro Gi 4p mobo using the new Bios?

Does the lower voltage affect the OC potential compared to say the 6174's for instance?

Any help would be greatly appreciated!

Sincerely,

Ishi
 
Dear Ishinomori-san,

HE chips have slight advantage over others due having some voltage
headroom. That said, chips-wise they should OC better as one can
bump the voltage shall stock voltage turn out to be insufficient.

As far as board/BIOS limits go, 230 refclock should be safe bet. YMMV
with speeds above 230 (few folks have run into issues >230 and we're
actively looking into them; others report no issues >230 on the other hand).

Also, note that at 230 you'd end up w/1.95GHz clock. This is still a bit below
stock 6172s (2.1 GHz). So I would say it all depends on procurement cost :)
In any way, 4p 6164s will perform better and more efficient than any 4p
octo setup seen to date.

Plus, usual OC caveat applies -- need good cooling.

Cheers,
tear
 
Thank you for the reply Tear :)

The cost is shapping up to be $350 a piece, i'd had a look for 6174's but the cheapest i could find worked out to be about $550 each at this time...

When you mention cooling, will 4x Hyper 212+'s suffice for the OC you suggest, also, what ambients would that situation work in as i live in Australia...

Sincerely,

Ishi

Edit: Also, what wattage would this system pull, assuming i just use 1 hdd?

Do you happen to mean "Dodeca to date" perhaps?

There aren't any cheap 6172 or 6174 CPUs on ebay right now. If you have time to wait, you can pick up 6172's in the $350-400 range. 6174's in the $400-450 range. At least that is the case for the US. I'm not sure the going prices for CPU's in Australia.

cheers mate...

The best i have found was 6174's at 490 each ($60 shipping though)
 
4 x 212+s modded to fit that board will work fine

Wattage estimate - 450-500W - my 6166HEs when I had them pulled around 460W, so you will probably be on the low side of that estimate.

No, he means octos. 6164HEs are the lowest end dodecas, and they are still going to be better than any octo chips out there.
 
Hey Musky, cheers for the reply :)

Do you estimate this configuration to pull 450-500k ppd on a 6903?
 
Probably a bit under that - 400K to 425K would be my guess.
 
My 6166he @ 1.98Ghz pulls 434w to 445w giving 439K ppd to 444K ppd depending on which 6903 WU it gets. PS type makes difference also, So does upload speeds.

I tend to be in the 450-475k range on 4x 6172's on 6903's, so, musky's estimation seems about right
 
My stock 4x6174 with 1333 CL6 ram averaged between 500-510k ppd. Dropping that from 2.2ghz to 1.97ghz, it looks like you'd be in the 440k range. Just my estimate.
 
Thanks all for the replys, muchly appreciated!

what strap are you using on your 6166's?
Also, what PSU are you using?

Cheers,

Ishi
 
I was gonna give you my numbers at 1.9 but rascal seems to have as close as a guess to the real thing as you can get. O yea, welcome to the forums lol, feel free to stick around, there's plenty more knowledge base here

Kinda cool that other forums send 4P questions this way, guess we really do have the most 4 P builds lol
 
I am still using the original OC bios running at 220, but still should be very close to the newest bios settings.
Have OCZ 1250w gold series psu.
 
IMHO gold series is the way to go, will pay for itself over time.
I went with 1250w gold as plans are for 4 more 6180s and they pull 750w stock:(
 
A good 1000 watt should sustain you if you plan on upgrades if you don't wanna go for that 1250 (although I bet that rig keeps in the sweet spot on that unit lol)

Hell, I've ran mine on a 750 lol, but he makes a point about the gold standard, with rigs like these on 24/7, a high efficency PSU is important, saves money in the long run, and they are usually longer lasting due to high build quality

But yea, you should be a tad over 400k at those speeds, my 1.9 ghz with slow ram (haven't adjusted the timings yet) is reported at like 395k, but I get a tad higher usually just due to getting odd units in-between bigadv's. Maybe 420+ with nice ram speeds?
 
Not seeing anything close to the numbers reported here with 6166he overclocked at 10%....
 
Which bios the newer one?

My TPF for 10% o/c is 15:30 average on 6903s

EDIT: I'm using original one still

Wow, so right around 1000 PPD/W. Nice! That's got to be about the best ratio so far.
 
Shit I just realized that, now I wanna test my rigs lol

I remember when we tried to break 100ppd/w lol
 
If you are in Australia then I would make friends with someone in the US who can ship everything to you for cheap.
I picked up four 6174's for $450 a piece and hardly any shipping.
It's a lot cheaper to buy hardware from newegg and have it shipped to a friend and then to Aus via USPS or whoever than buy in Australia (PCCG etc.)
Also if you are buying say 4 chips then you can ask for a deal (I paid $450 per chip although they were advertised at $550 or something).
Ambient in Aus isn't too bad as long as you don't have evaporative.

Good Luck

does that mean the 6164/66's would be right up there in PPD/w ratio?

Definitely. I still think that one of the 6166HE machines we have around here will end up being the champ for ppd/W. I have not seen anything beat rascal's numbers yet.

Cheers bud, i have someone offering the 6164's for something like 38-78 shipping total, at 350 a piece...

Thinking of the total cost for the chips, it would be $1350 (6164's) or $1750 (6174's) if, and i stress IF, i can find them for that price...

I found some 6174's on the US Ebay for 490ea, but he wouldn't do me a multibuy discount (for 4) and he also wouldn't combine shipping ($60ea) so yeah, for the gain i would get in PPD (roughly 100k/30%) i dont see the advantage by going with the 6174's...

This could all be me justifying it to myself, and willing myself to burn holes in my pockets... who knows, lol

Those are highly OC'd ES samples though aren't they?

NO they are standard chips. I am running the original overclock bios @220, generic memory that has been flashed, And using a 1250w gold PS that is 92% efficient in the 450w power range .

I'm even considering replacing my 6180s (with 6166s) since they draw ~750w stock and get just 80k more ppd. 300w for 80k is something I cant justify now.. That is reason I shut down my i7 2600k w/ 2x 460s, draws 450w+ for less than 50k.

At least until someone shells out the big bucks for a Dual Xeon E5 rig.

My 6180SEs pull ~770w with a 12% OC. They get ~680k ppd. That looks like it would be over a 200k ppd increase, right? At stock, they were ~590k ppd. I want to say they were <720w.

still, that is a 50% increase in PPD for a >50% increase in power usage, i'm guessing the 6180's cost a bit more then 6166he's as well.
 
I'll take them 6180s off your hands, rascal, just say the word :D
