How does it overclock compared to the 940BE.
I've seen some pics showing it overclocking to 4.0 under 1.55 volts.
Yet some show it needing 1.5 volt for 3.6 and that being around the maximum.
Also how does it perform for gaming is it better worse or on par with an overclocked q6600?
Some reviews show it slower at all resolutions compared to essentially all intel processors. Yet other's show it winning in minimum framerates and faster at higher resolutions.
I have been impressed with my 920, with 1 multi lower on the NB than whats in the picture It is game stable.
EDIT: oops no NB in pic but it is at 2560.

Only game I have installed right now is cod4 and it RIPS! 3.7ghz Phenom 2 is noticable faster/smoother than my 4ghz E8400. Guru3d noticed the same thing. 790FX/phenom 2 simply flys in this game. I'm re-downloading all my steam games right now so I'll be able to comment on CSS, TF2, and L4D performance when I get home tonight.
That's what most Phenom(I,II) users noticed,but yet they are ridiculed when they say this... The reasons could be many,but the fact is that Phenoms are excellent gaming CPUs,apart from being overall very good.Quote:

This is leaning to 920 it seems. How hot do your mosfets get with that htt / nb?Quote:

Unless your wanting to do allot of extreme overclocking/benching and need the flexability of the BE, the 920 will clock to the same avarage 24/7 OC that the 940 will. Its a good alternative.
Also the AsRock board is 1 of the only 2 board that I know of that has working ACC with PhII and it helps with lower volts.
So it overclocks just as good as 940 with similar voltage.
Guess it must not take much power if you can stress test it with only ramsinks on the mosfets...Matter in fact that's one of my worries blowing mosfets or the northbridge since most amd motherboards don't have good board cooling yet.
you can see here from the IES utility that when clocked to around the average useres OC with high volts it drawes less than 80w on the 4 cpu phases when loaded %100.Quote:

Copper Ramsinks on Fets.

What did you have the northbridge and hypertransport at for that?
I would think a 2,200-2,400 hypertransport with 2,400-2,800 northbridge would put more stress on the Nb and mosfet heatsinks. Not sure if it'd draw alot more power bumping the nb volts up some.
NB@ 2560 and HT@ 2000. I dont have anyway to measure the 5th NB phase but surely it would not be as much as the 4 cpu phases. The mosfets realy do stay rather cool to the touch.
So given that the Asrock does so well , do you think the GA-MA790GP-DS4H would handle those HTT clocks just as easily as it comes with cooling on the the mosfets etc? what was the other board that works well with ACC for phII ? Cant seem to find your board on the egg (canadian anyways :P )Quote:

What temps are you getting on your 24/7? and how much voltage did you have to push through to get 3.8?Quote:

Scythe ninja with 2 fans on it. In a CM690 case.
My 920 will hit 3.7 on my cheapo scythe katana ii but its not stable due to how hot it gets. At 3.5 with 1.51v, the katana ii can barely keep it cool when idle. As soon as its taxed it spikes to 55-58 c and after 5 minutes its above 60c. For now, I have it running at 3.2 on all stock volts. It idles at 35-38c and full load is around 50c. Once I get my water setup in a couple months I'm planning to run 3.6-3.7 24/7. The thought of using a $60 heatsink with a loud high RPM 120mm fan(s) is not something I'm willing to do. I kinda built my rig for quietness (see rig in sig). Water FTW. I think the 920 is a huge bargain and people are overlooking it simply because it doesn't have an unlocked multiplier. I absolutely have no regrets about going with the 920.
Here is a 3.2GHz (all stock volts) run with my GTX at 720mhz.

Seems like you guys are getting pretty decent clocks, but being out of the AMD loop since my FX-57 I m wondering will there be a higher chance of board failure pushing the htt to 260-265 for 24/7. Seems like phenom II's sweet spot is about 3.7ghz ish Temp Wise for Good aircooling, so would a black edition be a better choice for longevity of the mobo? My goal is 3.7ghz, 2400nb with 8gb of 1066 5-5-5-12. realistic on a 920? I know its chip dependant, but i m looking to cool it with a ocz vendetta 2, and going to have an antec 900 with 2 104cfm fans on the heatsink.. :P
realy I dont see any diffrence. I havent raised the voltage on anything at all other then the CPU itself so I dont think the high HT is a issue. Everything stays cool on the board tho I did add heatsinks as you see.Quote:

I only chose the 920 as there is more tweaking involved than just upping the multi's and not very many people were going with the 920.
Awesome info :D So the NB speed seems to be the heel, of the 920, it should do 2400 though.. that isn't really pushing it to bad is it.. although i don't want to cook it out and fry it either hehe, what would you say would be a reasonable voltage for 2400mhz.. or rather, what does it take on your 920 safely?Quote:

Anyway I also bought the 920 when they launched to see how well the PII's performed and so far my mind is beyond blown! The max I've clocked my chip to so far is 3.78Ghz looking through my screenshots, but I know I've broken 3.8Ghz if I could just find the shot. I did a quick test using the processor in dual core mode and cracked 3.93Ghz using 1.552v which is the max voltage I can select. I imagine I wouldn't have to use the voltage so high but once you get over a certain point with my board it starts to fluctuate a bit.
Either way I use 3.5Ghz as my max clock which I've already done the work to make sure it's 100% stable (all night stress test) though I haven't gone through and knocked the voltages down to their minimum states just yet. That run was at 3.5Ghz @ 1.456v which to me is extremely impressive for a locked multiplier cpu.
Even more impressive is that I don't even know what my max HT Bus speed is because I finally quick testing once I'd reached a ridiculous 372Mhz (not a typo) with all four cores running. That's just ridiculous for an AMD Quadcore processor and I have no doubts that it would go even higher, but I'm already at the point where I'm running out of low multipliers to use so I gave up before reaching the end. Wild enough I left the multiplier at 10x all the way up to 350Mhz (giving me 3.5Ghz) when I finally knocked it down to 9x so the processor speed wouldn't be up too high. I didn't want to mess with the voltages much so I just set the processor at 1.472v and started clocking then like I said I gave up before it did.
Stock HSF yielded 3.71Ghz for me before I put my Xigmatek/Scythe combo back on and continued. Temps at full load for the 3.5Ghz @ 1.456v test were 55C max with the fan on extremely low 658rpm (out of 2000rpm 110cfm fan). With the fan at max speed the temperature reached only 49C on the same setting. Idle temps are 27C for the same clock and roughly 22-24C for stock speed on 1.20v.
The highest Northbridge clock I've clocked to so far is 2.7Ghz and I believe it will go higher still as I haven't put in too much testing time just yet on that.
Kei
great results kei! and :welcome:
:welcome:
Sounds like a good chip. What board are you using???
Hiya Kei! Nice info, awesome results so far. :) My D-Tek block came in on Monday! Just waiting for the other parts.
Oops, sorry guys I forgot to list my system details.
ASUS M3A32 MVP-Deluxe (1406 Bios)
4Gb ram (Patriot Extreme and GeIL Evo One)
ATi 4850
2 Hard drives (non raid config 160 main 250 storage)
Xigmatek HDT S-1283 with Scythe 110cfm fan (run only at ~600 rpm out of 2000 rpm for 100% silence)
650W Cooler Master power supply
Thanks for the warm welcome, I've been watching/reading this forum for a 1-2 years now but only recently realized I never joined so I couldn't post. I like to find the processors flexibility which is something I don't hear much about, but I imagine that 'epeen' has something to do with that haha. I'm running right now on 3 cores instead of 4 to see what the power savings is like and overall performance.
For the longest time I ran my 9850BE in dual core mode with a reduced clock speed for daily usage and surfing duties. I don't mind turning the speed down when I'm not using it instead of wasting power. It's honestly even more amazing to me the ability a quad has when you add in the fact that you can run it with 4, 3, or 2 cores depending on what you need at the time.
batmang, I saw that pretty picture you took of the D-Tek. :D
