I would think you would be better off in a forum where folks are breakin' in similar rigs.

And thank for beta testing for all of us. That DFI mobo looks pretty cool. Is this the first sb700 mobo ???

i signed up for the xtreme system's forum but it wont let me post because "the administrator has not activated ur account"... it's been 2+ weeks

edit: still has sb600 on it... dont think amd has released the 700 yet

u'll absolutely love this mobo... as soon as u set ur eyes on it out of the package, everything about it says "quality"... the biggest things are the SCREWS+NUTS they used instead of damn plastic tabs with springs to hold the chipset heatsink assembly... and the board feels like it weighs a full 5lbs lol

236 is no-go... im happy with 234 being stable at stock voltages aside from slight cpu bump... i'll just wait on AT's 790fx overclocking guide on the 14th, been playing with this system for 3 weeks now, time to be productive again

230 HT is about the limit of Phenom ocing. If you want more Mhz you need an un-locked cpu - like the Black Edition Phenom.

Phenoms dont have the overclock bus that X2's did

went ahead and tweaked memory at 234ht just to get the last bit of performance i could... seems to be a lot of interest with phenom and whether or not to upgrade ur athlon64 so here is my setup and some benches... these specs are my maximum stable settings, meaning the system can be fully multitasked as though u were running stock settings with 100% peace of mind

234ht

phenom 9500 @ 2574mhz 1.3v <-probably headroom here with the voltage, didnt bother lowering

Go over to HardOCP and look at their Phenom reveiws. They claim that Phenom is not tolerant of overclocked FSB and must be Multiplier OC'd only. You need a Black Box Phenom which is multiplier unlocked. I think they said 218MHz was about as high as Phenom would go for them with any stability.

thx gigabyte employee

I am NOT a gigabyte employee, and I swear by the DQ6 series. ASUS used to be the best, but I have 2 now that are crap, P5B and P5K, and horrible vdroop. The DQ6 boards have NONE.

vdroop is a good thing and is purposely implemented

What ??? Are you trying to convince me that a $100 motherboard is better than a $260 motherboard, since its power supply system is inferior ? I would like to see that proved, or any good reason for it to not supply the correct stable voltage to the processor.

Benchmarks mean jackshite if your system ain't stable.

BTW, get a real aftermarket heatsink, like a Thermalright Ultra 120 Extreme, I mean you can afford a Phenom and 790FX DFI board, sheesh.

Vdroop is an Intel only spec, someone correct me if I am wrong.

NXIL, did you buy a Phenom? Your replies in this post lead me to believe you did. If so, how do you like it so far? And Iketh, DFI motherboards are meant more for "gods-of-overclocking" than for people who are building their first system/are fairly new to the game. I had been overclocking since I built my 25 Mhz 486SX system, and had owned computers for more than a decade before the 486SX, yet I was still stumped when I bought my first DFI board, and took a gander inside the BIOS. They're just meant for tweakers, who will do anything for an extra 75 points in 3dMark types.

*Hugs DFI nF4 SLI-DR*

Thats the motherboard I have. Except its the Expert edition ^_^ Best motherboard ever!

Ugh, shut up. Wondering how long it would take for some dufus to bring this up.

I honestly don't see it as a stupid question. The Phenom has a bug that could cause a crash at any moment, it doesn't just have to be virtualization, so why is it stupid to ask? What if he applied the patch and it went away?

who said it isnt stable????

You did... A lock-up is not stable, and you have said it does it all the time. And you haven't answered why you think a bad vdroop is a good thing.

For the power supply and motherboard to NOT be able to supply a constant voltage to the CPU is bad, and causes the possibility of instability, so don't try and tell me its a good thing, and by design, unless you can back that up with some facts. I have plenty to support to support my side, including virtually ever web site out there.

And Thor, vdroop is not an intel spec, its just slang for the voltage drop to the cvore voltage on a motherboard, usually only high on high draw cpu's, like quad cores.

And last, I wish somebody would tell me why they would buy an AMD quad core with the prices, overclockability and stability of the Intel quad cores available today. (unless you already had am AM2+ motherboard and memory)

 

[Duvie]

hard locks of any kind is a sign of "system instability"....

You vdroop comment is lame....


What is your HTT multiplier set at?

 

[imported_Iketh]

those are my benchmarks at my HIGHEST STABLE 234 HT.... i swear i think only 2 people have actually read this post

 

[Duvie]

READ!!!!!

M-U-L-T-I-P-L-I-E-R

not the same thing as HTT. I can read and know that is 234....Is YOur multiplier set at 4x,5x, or whatever?

and i said it does it all the time 235+, come on people

go right ahead and call that article "lame" mr. duvie

 

[NXIL]

And last, I wish somebody would tell me why they would buy an AMD quad core with the prices, overclockability and stability of the Intel quad cores available today.

Maximum PC Magazine, Feb 2008, page 49: benchmarks 2.6 and 2.3 Ghz Phenoms--suffice it to say that the stock Q6600 at 2.4Ghz beats the 2.6 Phenom in essentially every benchmark--some are close, but overall the Q6600 "owns" the 2.6 Phenom.

So, a Phenom overclocked to 2.574 Ghz is not as fast as a Q6600 @ 2.4, but at least it's "stable".....

actually I should have meant a lot of your general commments....

What he said makes some sense, however.

Since I have been a n AMD user for years I can tell you this is just not a phenomenom on INtel systems. So I balk a bit at that statement. I also as a serious overclocker for years can tell you most enthusiasts get better results on boards with lower vdroop. Trust me MarkFW900 did not turn off this "protection feature".

I also think he fails to go into the fact that while some vdroop is quite natural and expected. Systems with huge vdroop seem to be more prone to stability issues. Also notice my asus p5b-deluxe had a lower number of phase power modulation and had a huge vdroop. My DFI has less vdroop (about half) but larger phase power modulation.

Also I notice in some boards like the Asus the vdroop grew much larger as my speed iincreased again leading to difficulty achieving stability.

That being said I will take a quality board with lower vdroop anyday. My experience tells me I will get more out of my overclocking.


PS: calling out members for a new member....pretty ballsy. I have some thoughts about you already but I will keep them to myself so I dont get busted by the polite police. I am sure I will hear your mouth around here some more.

 

[Duvie]

so 234 fine! and at 235 you hit the wall?

I am not familiar with that board but how is the cooling on the northbridge? active or passive?

lol who cares???

spreading false information should never be tolerated, and trying to turn this thread into a "who's bigger than who" topic should also not be tolerated...

 

[imported_Iketh]

1872 / 234 = 8

NB and HT are at 8x

this dfi lists the nb 8x multi as hexidecimal 04 and the ht 8x multi as "1.6ghz"

Yeah I dont care either....I just think you could have a bit more tact when you are trying to ask for help.


Bottom line is you bought a system and platform not ready for primetime....I guess be happy with 234....maybe a few bios tweaks that come down the pipeline can buy you some more HTT. Seems like quite a wall though.

I am glad to see some ppl venture to phenom setups. Reassures me I wont be changing platforms for awhile. New Core 2 Duos and my first quad was pain free. Next to my p4c northwood easiest overclocks in my life
