What was your CPU VDD voltage set to in the BIOS here in your screenshot?

auto... what does that setting do?

[jonspd]

should be 1.35 AFAIK stock I think...

[SNiiPE_DoGG]

yeah, but I raised vcore to 1.44 I think there, anywho its at stock now as it had some issue.... I need my watercooling or a good aircooler before I can really test this thing, the stock cooler sucks...

I might rip apart permafrost and steal one of the MCR 320's tonight...

MSI mislabeled their voltages in every bios release. CPU VDD is actually the core voltage, and the CPU voltage is actually an offset for minor bumps in voltage.

[SNiiPE_DoGG]

well that explains my issues... LOL

[TiTON]

Bingo have you tested quadfire for bugs? If not I will tackle that this week......I need it to work 100%

Waiting for the 13C7 bios
C = cold very very cold

Chew - which quadfire bugs are you talking about? I have played quad fires both ways with this mobo

It's the same with the CPU NB and NB VDD, they too are backwards.

It was more of asking than anything......Not sure if HT clocking is an issue with 4 slots used......or if any other issues arise with 4 slots full as of yet.

[SNiiPE_DoGG]

Guess who has Animals in the mail???

[chew*]

Those do nice on this board.....I found my sticks did well at 1.69 which is still within spec for warranty.

Definitely going to grab another set for my everyday rig when and if its ever up and running......

Hardcore benching though is high stakes so I'm going to have to jump on the elpida train for benching ram.

Still kicked my 2x1g high volt D9 GTR corsairs sticks ass with the animals though in 3d

o rly? Nice to know that before I start clocking!

LOL, I just do not see a cold BIOS coming anytime soon but they may surprise us. I have not tested all four slots with anything over a 4870 yet, but two 4870x2s work well on the board. My favorite setup though is four 4770s, light loads, killer performance for the money but not anything that is going to win benchmarks.

[TiTON]

Chew - does the board have colb bug issues? I haven't seen or noticed any.. are we talking like LN2 -196c cold bugs.. are like LHe cold bugs?

PS - one of my MSI board is alive So going back to it for playing. I noticed MSI also have drive strenghts

[chew*]

Nah Titon I haven't put it under cold yet but a 1 off bios tuned for cold would not hurt a bit and would feed the need for us guys with a few screws loose.

As far as drives use the force

[TiTON]

Ahh.. well.. i will keep my fingers crossed for one of those cold bios editions Tonight going to put the processor on phase, so i can dial in the cards and vGPU, as well as a different set of ram. Will probably go simple water on the GPU to see any increase in performance before putting these bad boys on LN2. Hopefully by the time the LN2 for the GPU comes around, i woudl have figure out how to get a 6Ghz 3D06 run

I will keep everyone posted.

For kicks I used chew's settings a few pages back, booted right into vista x64 at 3.8GHz Instant BSOD when I started prime though I was able to POST at 4GHz as well, that was too cool.

Currently running prime at stock speed but with NB and HT both at 2400. So far, so good. Not sure if I should play with the memory speed or not, I'm at 1333 7-7-7-18 1T. Just playing around right now.

My 955 has a VID of 1.35V. If I adjust CPU VDD voltage in the bios the VID changes in coretemp to whatever I set that at. Interesting.

Which RAM are you using? I'm running the OCZ in my sig and I had no problems last night setting them to 6-6-6-18 1T running 234 on the bus and at 3:8. CPUZ shows 624Mhz on the memory. Haven't touched the voltage yet on it so I'm confident there's good headroom left in these Reaper CL6 sticks.

[Sparky]

I wanted a set of OCZ reapers 1333, like 65 bucks from Newegg. Maybe that's what you got? They were OOS so I grabbed some G.Skill PI that were similar in specs and price. F3-10666CL7D-4GBPI 4GB 7-7-7-18 1.5-1.6V. I may play with the memory, but I get lost in the sea of timings and I'm afraid to touch them

*edit* I tried 1.65V at DDR3-1600 with stock timings. No POST. So now I'm at 1.6V at stock speed with 6-6-6-18 1T running prime. I think that PhII prefers tighter timings over higher ram clocks, so I'll aim for the timings.

Forgive me if I missed it, but is there much benefit to playing with the bus speed or should I just leave that at 200?

The tighter timings are crucial to get the most out of your CPU OC for sure. For now since I'm still on the wimpy stock HSF, my goal is highest OC on least amount of voltage possible keeping temps under control. So far with just a small bump in voltage my 720 BE is consistently idling at ~4C over ambient room temperatures, and loading about ~8C over when under full load in SuperPi. Obviously that's just one core under load so I imagine it will get a bit warmer with all 3 going at it.

As far as bus speed goes, my experience has always shown the most performance from a higher bus speed and smaller bumps in the multiplier rather than just cranking the multi up. Clearly you have more factors that affect stability, but increasing the bus speed has a noticeable positive impact on your overall bandwidth.

I've been messing around with the drive strengths, be it not that long, but didn't gain that much in terms of stability or overclockability.

Let me know how things go with your board :-)

[TurboDiv]

Im getting my mobo in a day or two. Do any of you have the official 1.3 bios that is on the website ? Also any of you using MSI LIve Update Utility to update the bios ? Thanks.

[SNiiPE_DoGG]

just use a USB stick and the utility in the BIOS menu, its the easiest BIOS update system I've ever used.

[TurboDiv]

So i put the bios file on my USB stick and than reset the computer and go to BIOS and to the M-flash USB stick utility ? Do i need to make it like fake 1.44 disk first or M-flash does it all by itself...? Tanks again.


PS: I see that some people have problems with USB keyboards, well i have Logitech G15. Will I have problems logging in the BIOS or I will have to go get a PS/2 keyboard ?

[FlawleZ]

So far so good on toying around with this 720 BE + GD70 combo on air. Minor voltage bumps to get some SP1M runs at 3.5Ghz with better timings and temps were still good on the stock cooler.




Although, doing some 32M runs and other stability tests tonight proved things were a bit flaky for sure. The stability problems were a bit strange and it got me thinking, I'm still on the v1.0 BIOS.

SO, my question is, is it safe to assume the v1.3 is the recommended BIOS currently?

[Tony]

1.3 is awesome, 1.37 is a little better still

You need to flash asap
