I tried both the white and blue dimm slots, same result. By increased V-core to 1.5500V (in BIOS), it seem to be stable Prime95 (1 hour so far), may be not about memory stability issue. That's not really good, my old P5K Deluxe can do it with 1.5V!! This board seem to be a v-core eater!

/Even if can not pass Prime for a minute, I can work and play game with those settings day by day without having any problem (system crash, dumping physical memory, etc...). I have used some boards before, such as 965P-DS3, P5B Deluxe, P5K Deluxe and I had an experience that if the system fails Prime test in a few minutes, it can not run any heavy task like game and 3DMax render! So can you give me an advice?

Problem is probably low NB volts at 1.31v try raising it to 1.45-1.55v and manually setting subtimings. You might need to bump FSB volts from 1.3v to say 1.35v or something

guess you guys already know about this:

Edit: Just noticed it finally hit USA today

Clubit is a very large (and fast) vendor.

Had a try! Rise NB Voltage to 1.55, FSBT Voltage to 1.35, but it still fails Orthos after a few minutes (BSoD), the only way to solve this problem that I found is to rise v-core to 1.53725V in BIOS / 1.5200 Idle / 1.5120 load. A bit disappointment to me, this mobo need more v-core than the P5k Dlx to make my E6750 stable at 3.6Ghz (450x8). Hope it'll overclock Penryn well!

I was seriously think to buy the Formula before my E6700 was dead, Now i know i need it for my E6850, any advice should i wait the X38 before take a decision?

We know the bios will certainly need some version for be mature, anyway i have work a lot with newer board, and little bug are not really a problem

I have build my Vapo today with my E6850, but i will be limited on FSB and more by some divider give no boot ( example 460x9 11xxmhz on DDR)..

" Nothing to do with this, but i was testing CPU with the last version of SandraSys, and they have add the result of FX76,( for recall, it's 2x FX76 dual core on a dual socket motherboard..) and i m really suprise of the result compared to a QX6800:
FX76: 38'855 Mflops
QX6800: 36'883 Mflops

did you enable loadline calibration to prevent vcore droop ?

might as well wait for X38 if you're on the fence right now

Yes! This option look like "CPU V-core Damper" in P5K series, and I always remember to use this!

Lane · 08-09-2007, 10:16 PM

Yes, but i don't know exactly from where it comes.. anyway you remember sometimes ago i have kill my P5W64 and replace it.. same rev ( there's no revision change for P5W64) and with the E6700, i have not really try max FSB with the new .. , i have switch for last , so the max 470mhz ( boot and SPI) a long time ago on my older P5W64 is perhaps no more valid with this board, or again bios can be a problem, i need try see if 402 and 502 bios give me better result. ( last is 903, and it what i use right now.)..

Will see, but there's not a lot of luck the result will be impressive on this board with a multi locked at 9 max..

I know me well, and if a morning, i m tired of a bad OC, i will send a phone to a friend shop and order a Blitz...
