Probably this chip can do a lot more,the only problem is how to keep temps low.
When i get the watercooling i will give it a try with ice water.

Nice OC! What's your load temp? And what vcore did you set in BIOS?

Thanks.
Load temps?No way,i don't even try to stress it with air temp at 32-35ºC,i am on air cooling.

That was only a test i was trying to hit 3.0Ghz with the less voltage i could,for every day use i run it at 2948mhz and my load temps goes up to 65ºC so is not worth to stress it at 3.0Ghz.

VCore voltage in BIOS 1.1125v.

What FSB and what multi the CPU tab shows on CPU-Z?

The everest gives CPU/9 and CPU-Z CPU/10.

Can you give us a validated CPU-Z?

cpuz shows something wrong...it should be 1:1 and i dont know why it shows cpu/10

I just swapped out my Opty 165 for a Opty 170 LCB9E 0651 RPMW.
I'm 10 hours in running dual prime on Linux at 10 x 300 1.4V.
I'm hopefully on my way to the 3GHz club for the first time.
This one is running cool at 40c under prime on water.

My opty 165 took me to 2800MHz but lost stability over time.
Was last running it at 2.5 GHz.
That chip ran hot and needed 1.6V to achevie 2.8GHz.

My 170 was bought it at Newegg and it arrived two days ago.
Running DFI Lanparty UT NF4 SLI Expert.
1GB Crucial Balistic Tracer.

I'll post more once I'm sure it's prime stable.

Almost the same stepping I have, LCB9E 0651 MPMW, but it seems my memory don't want me to clock it to 3 ghz, may also be temperature, can boot at 3 ghz, but not stable for prime or orthos (the same basicly), and since my memory only wants to go to 260mhz and the only way to do that at the present is to clock cpu:ram -> 1:1 .. I gain alot from having my memory up there although I would really love get my 170 up to 3 ghz, that would be really sweet It clocks from stock 2.0 ghz @ 1.35V to 2.6 ghz @ 1.375V but I am suspicious that it is the memory controller that needs more voltage when I "OC" that ridicoulus 10mhz... my memory sticks are 250mhz, but when I say "oc'ing" really ANYTHING above 200mhz for memory is an oc

I don't know why this happen,CPU-Z shows that your divider is 11/12 and not 1/1.

Both everest and CPU-Z work fine on my board and they give same results,a conflict maybe.

Holy load temps! WOW..Thats with 1.1 core volts? I was loading @ 38/32 when I was running with the HS installed @ 1.568 volts! Once I removed the HS everything dropped to well below stock setup @ 1.35volts. I would remove the HS on that sucker and let the OC'ing begin personally! Want to sell that processor

That is with 1.1125v.

I will think about removing the HS,what difference will make in temps?

No,not before i push it well over 3.2Ghz

1.1125v (?) is insane lol. Do you have CPU overvoltage enabled?

[stealth]

Yes,1.1125v in BIOS plus 0.205v that Overvoltage CPU vCore and mobo adds 1.3175v in windows.

I see your HT-LINK is at 1365mhz, did you have to enable overvoltage SB and/or NB to make this stable? Any physical mods to the board? I removed the cooling-tape on PWM-mosfets (there's a long aluminium-cooler over the PWM area, I simply took it off, removed the tape and put on som artic cooler ceramique paste instead).

No,nothing is overvoltage on the mobo,the only things i have enabled is OverVoltage CPU vCore and DDR VCore.

I can push the HT Link up to 1600 without any problems.

No mods on the board,still as i got it one and a half years ago.

Once I OC'd my 165 I was having temp issues like you are. My idles where 42/38 and under orthose they immediately went to 60 and would slowly creep up. I went with a water system instead thinking air just wasnt good enough, on h20 idle was 42/38 and load was exactly the same. I really didnt want to remove the HS, but I wanted to maintain the OC I had it was required. Was easy following the instructions here, and now on water the idle temps are 32/22....under load after 24hours of orthose the average temp for cores was 37.3

It made a huge difference imo, but I dont think I had good contact on my processor w/ the HS.

Those are some interesting results you have as well...Very nice.

And blah....my A8R32-MVP doesnt like anything above 1500 for HTT

[stealth]

Thanks gromet,

Very interesting...........i think i will follow the same steps,see how is going with the watercooling first and if temps still high then i can remove the HS.

Well,at the moment there are other priorities,so i have to be patient it will take a few months to get the watercooling.

[biohead]

Mine doesn't either, above 1400 will corrupt my drive if I don't watch it. Doesn't matter though, 283x4 still gives me ~1133 which is good enough. Remember not to push your HTT too much, because first of all it doesn't improve anything, and second, too high may lower performance because of errors in the HT link. Though I've also found HT speeds (too much) below 1000 to cause instability as well. RD580 likes it above 1000, just don't push it.

Hello all. I have an opty 165 CCBBE 0615EPMW. I have had it very stable at 2.9 / 3.0 . expect for Super Pi . So I think it was the memory. Sorry don't remember the specs.

My DFI LP NF4 SLI-D died and I have sold off everthing expect the chip. I wanted to go Nforce 8500 anyway and replace the memory. I had some OZC pc4200 (ddr500) Gold EL stuff.

I broght a OCZ powerstream 600W. I have a Hyper 48 cooler.

I have a board that I will be selling but wanted to test the chip.

If this chip is good should I stay with 939 or go AM2? What board and memory should I get? I have tried reading thur all this tread but more confused than anything.

Thanks so much.

There are guys in here that they know more than me and they can tell you what this stepping can do.

What i can tell you is that is not a good time to upgrade,not before Quad core is out.

As you said you have the board and you have the chip so you don't need much to make it run.

If you upgrade now to AM2 in a few months when Quad core come out AM2 will be past.

Look what happen to 939 socket,i slept the night and i had a high end machine and i woke up with a dead socket.

CCBBE are some of the best Optys around imo. I have a CCBBE 0617 that runs 3.0ghz stable (I need 5+ hours before I say stable). Now I do question your "stable at 2.9/3.0 but cannot run Super Pi".....I can run superpi all day long, but fail at real stress test (orthos or prime95 in less then 10mins). I've run PI @ 3153 but have failed orthos in 10secs...So what is stable? I dont think PI is a very good example (depending on the size I guess), and I really question you failing PI but being stable. I think the system was unstable, but you ran it @ that speed. As long as your not having issues, whats the issue right? I just perfer being completely stable as can be in my OC.

The processor is good...will fetch a decent price on Ebay or somewheres even though 165 prices are under a 100.00 now. As for your question? Are you asking weather to rebuild or go AM2? Personally I would go AM2 w/ a 6000+. With a good stepping you can get 3.5ghz which is impressive, plus the increase from DDR to DDR2. I remember reading that when the AM3's come out, they will be backwards compatable, meaning you can run a AM3 in a socket AM2 setup as AMD feels the price of DDR3 is too expensive. I would do some research on this to make sure, but I remember reading something along those lines, but maybe that is AM2+ setups. If I was going to build a new setup, thats what I would do, especially if later down the road I can upgrade to a AM3. S939 is taking a slow death...but its coming.

[bernardmem]

I am thinking on the same lines. If I have to pay for all new stuff (not counting the chip) I may as well go AM2. Pricing is about the same for either.

Sure AM3 is due out soon but who is to run out and do it for several months until most of the issues are addressed and price are a little more inline.

If I going to have "old" stuff , it may as well be "new old stuff".

I have an old celeron (a what?) 2.8ghz socket 487 I am thinking about getting a board and some memory for and using that awhile until I can everthing else together. A little over clock to 3.0 and say a gig of memory should be able to do what I want.

Anything is better than this PII 500 thing I am trying to on now.

Thanks for the input

Yea...I plan on going AM2 towards the end of the year getting ready for AM3. I dont think DDR3 is coming down soon in price. I'm just waiting for more boards that are AM2+ to come out, specifically one that supports Crossfire (I like my 2 x1950's right now). Soon as I find one that I like...the 6000+ is under 200! Thats great performance for so little, and the new steppings are getting great results.

Just so you know I have the same stepping 165 and I can't get it 2.9ghz orthos stable no matter what voltage I put on it. Right now I'm sitting on 306x9 on stock volts, 12hrs orthos stable. I just got this cpu a few weeks ago so I still have some experimenting to do, but I think I've reached my limit on stock volts.
I'm surprised that you can even boot up windows with 3.0ghz. I'm just saying that that cpu may not be that good.

[Heikit]

gromet, ot, how much voltage to you put your crucials?

Im running 2.85v in the bios on the cruicals...

Right now Ive been playing with timings lately seeing which is best, but its coming out more mhz seems better then tighter timings for me atleast.

I put in a larger divider and I'm currently at 214mhz with 2.0-2-2-5, was seeing if it increased any performance, but I actually seem to have lost slight performance from 272mhz w/ 2.5-3-3-8

[bernardmem]

Well folks, my problem , at least as to which platform to go with. has been solved. My 165 is toast!! I got the Infinity R482 in and tested it with the buyer's 148 and it posted fine. My 165 did not. Not even a beep or keyboard flash.

Oh well, it must have been what caused the board to fail as well. Everthing else (memory, video, other cards) are still good.

Great chip while it was running.

I am going with a Biostar 7050-m2 and a Brie X2 3600 or higher and some good memory that I can use later. This is enought for me right now and something I afford. I can add a 8500 or higher later if I want to.

Stealth thats a nice oc with such a low vcore. I just recently got into OC'ing but never really would a forum with such a wide database for OPTY's

I have a opty 185 @ 3029 (13*233) on air but the vcore is too high for comfort.. which equals to too much heat. If there any other settings i can change to i can boot with lower vcore?
