Phenom II 920 goodness thread

**zif33rs** · 01-04-2009, 12:17 AM

Well...after realizing I was problay crapping all over the "official" Phenom II OC thread I started my own so I can post up on what seems to be a pretty good chip. I'm sure the 940 is going to be great but having this 920 for just a few hours now I can say its performance easily surpasses the 9950 that I have. Running smoothly at 3.22GHz on default vcore is nice.

I will start filling some more benches later. Just passed a nice 3d06 at 18k, This is about 500 points less than my 9950 ran with crossfireX at 3.5Ghz(4870x2+4870). This is a single card run(4870x2). It "feels" faster...

well...20 minutes plus of Prime95....its running in the back while I post this...snapped a screenie..opened paint...downloaded to my host...and posting here. Im impressed.

Do you really think that this results are amazing? The oc potential of deneb core is much higher, try to reach 3.5GHz and more

.

**zif33rs** · 01-04-2009, 01:18 AM

Not amazing...impressive...two different things. For just having the chip for a few hours I can say that this compares well to what ive seen from the 940. Some are running 1.45v+ to reach near 3.7ghz. I have a feeling that is within this chips reach. Im sure if my MB can reach close to 300 HT multi then it will be amazing.

I guess whats really doing it for me is the fact that I still have Prime running and Im able to still use the computer as if nothing was going on. Over 1 hour now, my 9950 would be having fits.

i think that that looks awesome considering that its a locked multi chip, i may have to go p2 when the full am3 ddr3 chips are out

**informal** · 01-04-2009, 01:26 AM

I think the OP is referring to temps at those clocks and voltage needed(stock).It's a nice score for a locked chip,gaining over 400Mhz on stock vcore and staying very cool is pretty impressive.No doubt phenom II 920s will go a lot higher(think 3.6-3.8Ghz on good air cooling),but for a fist "quickie" run ,this is a very good result!

Compared to 9950 it uses around 2x less power and is substantially cooler at the stock and OCed frequency while running around 10%(average) faster per clock than Agena.

Now this...this is really amazing...

still at default on all voltages. and Justapost im on water

What ram you using, You should be able to tighten the timings a lil, and I believe you can extrack a better score then that aswell

Edit, I was going to say get that NB up and well You post fast lol...nice job

**rockfella** · 01-04-2009, 08:01 PM

Water does the deed

still very impressive!

He He what cooling do you use?

**zanzabar** · 01-04-2009, 01:28 AM

i dont see the point of the 920 for acing the 940 black should retail for $75-100 more ($300-330 or so or less) and it looks like it will be worth every penny

if u can oc like that then use a higher multi it would be 2x amazeing

**Macadamia** · 01-04-2009, 02:13 AM

Actually, 4.0 is doable on water regardless of chip I think. :P

**zif33rs** · 01-04-2009, 02:21 AM

ok..4.0 it is.. :P I need to sleep though..been fun for now...leave you with 3dmark 06 at 3.5ghz. Needed to add alittle vcore though. Crashed the first time at default...added .5v to vcore and .2v to memory and got this. Have alot of tweaking to do. I havent messed with memory timings or anything at this point. 20k+ should be a snap. On a side note..ORB isnt letting me make these public...imagine that.

gnight all.

**bedlamite** · 01-04-2009, 05:05 AM

Uh niice

Go for more

**duploxxx** · 01-04-2009, 05:23 AM

nice that would also be possible on decent air, we already see in europe some 200eur range for this 920, will replace my 9850be real soon.... just a few more days.

**TL1000S** · 01-04-2009, 05:41 AM

Very nice zif33rs!
Thanks for sharing.

**leoy** · 01-04-2009, 07:50 AM

I'm pretty sure the 920 model will be at least @ 3.7-8 Ghz for 24/7 with good voltages(<1.5v). The 940 will be around 4 easily....

**zif33rs** · 01-04-2009, 09:22 AM

at 3.65ghz, 2600mhz NB

1.45vcore, 1.4v NB

looks like BE is not needed at all for normal air cooling configs.... tempting to buy one next week and not waiting for am3 procs.

**Caveman787** · 01-04-2009, 01:35 PM

I think he just hasn't dialed in the voltage yet since he's been doing steps so far slowly increasing the clocks.

Isn't 1.4v nb really high? specially when I thought it was like 1.12 or something stock.

Makes me fear for the mosfets and northbridge.

Temps from what I can tell havent peaked above 27c on the cpu die..for some reason im not getting any core temp readings.

Does the HT Ref clock seem to go higher using the PhII? I pushed mine to the limit on the Asus 79-T and could only get 250 with stability (was just testing for limits). If anything is keeping you from going higher that may be it.

Personally I only up the HTRef to tweak the memory and use multis for everything else, but those are some pretty impressive results for a locked chip!!

Can't wait for the 940's...

Seems The HT is bound to the MB maybe getting alittle higher with the Phenom II but as of now I'm having a hard time getting over 270

P.S. @zif33rs, that are good clocks now, good job

Thanks Stuen4y

Also I dont have any problem with high voltages Im running 3.3ghz at 1.48v but the thing Im saying is if we want to hit 4ghz what voltage will it take....the lower the better......my goal is 3.8ghz for 24/7 and a high benching speed of 4ghz.

Yea..its taking me abit to dial this in..right now I'm at 3.7ghz at 1.475v. Seems to be pretty stable..havent primed yet...running some vantage and cinebench now.

Havent found max NB speed yet...tuned NB speed down to 2400mhz to match HT link speeds for now.

Thanks villa1n, the board is staying VERY cool compared to my 9950. Max system temps are 34c

My mother board has two setting for NB voltages. One seems to be direct to the NB(set at 1.4v...up from 1.3v default) and the other is NB VID. This is default at 1.175v. I have added up to .05v here but it is VERY sensitive. I think this is the voltage causing people to blow MB's

Thanks every one for your interest..Post any Benches you would like me to try out and I'll see what I can do.

p.s. First Vantage run at 3.64ghz

Yes, this was my concern as well, as I am considering grabbing and building one of these in the next couple weeks.. but not sure on what mobo's will be able to support high htt clocking.

Edit: zif33rs, you just posted as i posted this... 34C sounds great, doesn't sound like much chance of burned mosfets or northbridges with those temps

**Demo** · 01-04-2009, 09:57 AM

Looks like at 3.6Ghz is almost able to catch up with the Q6600 @ 3.2Ghz, good one for AMD

Sigh... http://www.xtremesystems.org/forums/...&postcount=269

Clearly the Q6600@3,2GHz is not beating the Phenom II@3,6GHz when the Phenom II is equal or better than Kentsfield both at 3,7GHz.

**Caveman787** · 01-04-2009, 10:12 AM

I'm assuming he meant in super pi.

What type is the G. Skill if it's pi black you should be able to get pretty tight timings.
