good job:up:, what voltage did you have to use?

WOW the new PhenomII 940 just did a price drop here. then they came out price was 375.00(CAD), now on Newegg.ca there 310.00.....920 are 265.00

WOW....Check this out. I found out about the 15 dollar Phenom II 940 discount late so I contacted Newegg and they are giving me 15 bucks back(Promo Code). Thus, getting my 940 for 215 due to buying a cheap 16GB flash drive. (15 Dollar combo discount).....Plus a 10 dollar rebate for the flash drive.(LOL)

SO what are you buying me?

So, you are finally getting one?....:yepp: Have fun man:up:

I forgot it doesn't show that. I had to use 1.5v.

Funny part is at these settings my CPU gets to 72C and my chipset up to 75. :( It's never been that hot before. I calculated repositioning my heatsink knocked off a couple degrees from the CPU, but didn't do much of anything for the chipset.

Daveburt714, yes, at stock my system is fine.

Had to. I couldn't resist. I have spent almost 500 bucks at newegg with in the last 5 days.:up:

That sucks man... I hate to say it, but it sounds like you may have gotten a turd. I'd be too honest to RMA it if it did what it was supposed to do, reguardless I feel for ya... :yepp:

On the bright side, Phenoms are tricky chips keep working at it you may very well be able to get better clocks. :up:

I'm hoping for a magic BIOS sometime in the future. :p: At the very least I'll probably sell off this chip and buy an AM3 one later on. By then AMD's 45nm will have matured some more.

Well, it's not real impressive, and I seriously doubt it's 100% stable, but it was good enough for a CPU-Z validation, and it's still holding it's own while I post this message.... :p:

Personally, anything under 10secs on WPrime makes me feel good... :up:

I'm still working on my tweak abilities, It might actually do better, and let me get an hour OCCT verification.. :D

Heres the CPU-Z Validation link:

I love this PhII, and in the end, it's just your average retail chip, SWEET... :D

Probably the best thing of all is the ~2.7 NB speed! My 9950 would have never even come close to those clocks... :up:

:rolleyes:Dave, mine is similar to yours clock wise, but require 1.52V for that clock. I've did some 4 core Cinema stuff on previous page, but OCCTP 1H failed after 6 minutes when temp reached 57C. Better cooling or more volts and 3.9GHz in 64bit stable!

I'm now going to fire up my main ring and figure it out :cool:

I see you are using the same motherboard as i do. Can you go past 265mhz bus speed? Mine just won't boot. :(

Some more benching at 3.95gig on WATER trying for decent ram and NB clocks atm , rather than outright clk, which seems to be difficult on wat over 4gig. :)


3000kb/s+ WinRAr @ >4ghz DONE.

cpu99 score aint bad :)

sandra mem bandwidth... nipping at the heals of TRI channel corre i7 ;)

and last but not least.. PHenom II has to win something :)

Could you please run the Everest's cache & memory benchamrak with the above settings?

Thanks for posting your results on water, nice clocks, but from what I have gathered 4Ghz prime95 stable seems to be out of range with the current stepping of Phenom II.

Thats what I was hoping to see, Im sorta holding off on getting one now, as it looks that 3.8Ghz is more realistic for prime95 stability using water and moderate voltage increases.

Also waiting for the prices to drop in the UK, such a shame that US retailers dont ship to Europe, so we can benefit in better pricing........

mAJORD, your Crypto bandwidth should be higher than mine, but it isn't - I'm running at DDR2-960 memory 4x2gb, and FSB 240 x15 = 3.6GHz CPU, NB at 2.4GHz (10x) and HT at 2.4GHz. That's kind of weird. Your HT multiplier is different from your NB, that must have something to do with the motherboard you are using.

Crypto
Bandwidth 542 MB/s (you got 441 MB/s) - big discrepancy
Hashing 660 MB/s (you got 687 MB/s)

CPU at 1.4V, NB at 1.3V right now. I've tried 1.6V on the CPU and 1.5V on the NB but I can't increase the speed of either without crashing the system. Not quite where I expected water cooling to get me. I'm guessing it is due to using all 4 memory slots.

His should be better than this test I did...

I went for it. I picked up 8GB of G.Skill DDR2-1066 just now. It's supposed to clock well, but I'm wondering about the PII IMC. Has anyone had luck in doing 1066 with 4 DIMMs yet?

I like your memory scores :)
Good work mAJORD:up:

Has anyone seen Phenom II with 0901xxxx batch?

you can do 3.8 stable on air too

Toppc did 1120 on a MSI DKA790GX-Platinum here: http://www.xtremesystems.org/forums/...5&postcount=26

Best I can do stable with 4x2gb is FSB 240, DDR2-960 5-5-5-12-20. Sandra scores are very good [improvement over 9850BE, 3GHz, same memory settings and NB speed]. I was able to post at DDR2-1066 speed 6-6-6-18-25but the memory was not stable, and I could not boot at all at DDR2-1100. I have also tried FSB 250, NB at x9 (2250MHz), DDR2-1000 also not stable at 5-5-5-15-24.

Memory
Int 12.08 GB/s [ 6.5%]
Float 12.06 GB/s [ 6.5%]
Latency 77 ns [ 6.1%]

Curiously the Multi-core efficiency is way up in Phenom II, but way behind Core i7. It's probably not a very good test. Up 45% for a 20% increase in clock speed.

Multi-core efficiency
Bandwidth 5.45 GB/s [45.3%]
Latency 78 ns [44.3%]

That is suspicious, since multicore efficiency went way down in Cinebench. Instead of a speedup of like 3.8-3.9 we're seeing 3.6ish on Phenom II for whatever reason.
