nForce 790i SLI/Ultra chipset mobos - Reviews/OC/Guides

[GAR]

lets just hope its a good bios, i will be home in 3 hours, i will test it then and report back.

[3oh6]

oh its good...it is basically the same as P03R2 from what i have checked thus far. clocking appears to be the same as P03R2 for FSB and Memory and performance with P1/P2 enabled at high FSB is nearly identical. i am fully confident everything else will be the same as well. but don't expect any miracles as far as the corruption issues goes guys...just enjoy the performance and clocking

i just started stability testing the FSB but this is exactly what was 12 hr OCCT stable on P03R2, i even turned down FSB voltage a notch. this is on P04 thus far...

try using those settings with GTL values in positive figures (instead of -30 use 30)

assuming you are limited by FSB

otherwise what is the issue with your setup again

I actually haven't tried negative values (Although I have considered them).

What I did try were values ranging from +10 up to +35mv. I have a bit of experience with GTL values working with the DFi boards, so I know it's about finding that sweet spot.

However to be honest I started to feel like I was p*ssing in the wind with the 790i.lol. Which is why I swapped to the P5E Deluxe. Quad up to 3.82ghz @ 1.5v stable.

My memory which i paid what 90 pounds for OCZ 8500 golds DDR 3(1066) 7-7-7-21-1T, I managed to memtest at 1700mhz 7-7-7-21-2N @ 1.94v. So components seem to be just fine. As mentioned previously the P5E has been a breeze to work with.

Now P4 bios is out however, it's time to swap back and have another blast. Fingers crossed

Let me help ya there.
You meant to say "I started to feel like I was p*ssing against the wind".
Now LOL properly

P04 is a GOD!!!!!!!!!!!!

got 3000+ bandwidth and latency is now at 49ns, passed prime blend for a bit as well..............so far so good......this board will finally shine like it was meant to be.

im running 450x8 memory at 1800mhz sync with fsb at 1800mhz as well.

Nice to hear that Gar

I search to boot with QX9650 on XFX NF790i board but i can't with 01 and 03 rom.
Have you ever to pass YOrkfield CPU on this board?

[bellinghamwa]

I am running stable with the voltages below, but someone mentioned my VCORE (Auto - 1.32v) should be manually set to 1.20v or lower since my E8400 OC is rather mild.

Can I get some more opinions on this?


CPU Core - 1.32v (Auto)
CPU FSB - 1.35v (Manual)
SPP - 1.40v (Manual)
MCP - 1.50v (Manual)

CPU temps are 36C idle and 49C Load.

I stand corrected.

Well swapped in the 790i with a stinking hangover, and have to say much happier. Don't want to temp fate, but I think the clever chappies have cracked it with P04.

Passed memtest. Volts on ram @ 1.85v p1 p2 enabled



The P5E Deluxe was a great board, however even with the q6600 cranked to 4ghz I could barely make 19,000.

It seems where this board excels is in the HDR tests, especially Canyon Flight.

Cpu volts droop to 1.5v under load, which is really what I want permanently. Have to set 1.6v in bios. Not sure whether to enable c1e. If they could introduce voltage calibration into the next release that would be top.

Now a question. Is it possible to install Raid using a USB floppy Drive?

Cheers

don't use auto vcore

always set it manually

and you should be able to be stable at 4GHz with that much vcore so drop it a bit i'd say

[eternal_fantasy]

Has anyone been able to set FSB over 425 stably with both P1 and P2 enabled with a quad processor? I managed to boot once at 445 and got around 12200MB/s read, but then it never happened again...

Above 425 till about 430 is possible but if I restart the system reset to default settings..... and above that if I get it to post (with 1.4V VTT) it would say some OS file corrupt, and I had to reduce the FSB to start windows again.

[RLM]

My 9800 isn't the best overclocker. In fact pretty poor compared. Even so having a bit of fun



Certainly happy with these sticks so far

Does that setting stick after restart from Windows? if so what is your memory and voltage settings?

[evildimitris]

Memory is the CellShock 1800 - 2.0 volt

i do restart always and never have any problems! never i lose the fsb or ghz on cpu

This bios is amazing, rock solid at 450fsb, and 900mhz mem 7-7-7-24-2t 2.0v, loving it

did you ever rock the P03R2 BIOS? if so, has P04 improved on it?

with an E8400, i am finding absolutely no difference in P03R2 and P04, performance or overclockability wise. P03R2 was really solid and clocked better than could have been expected and P04 is just as good thus far.

[Benji Tshi]

Yes, it seems that the p04 is better than the P03, we are experiencing it with Dami1stm. The board works with the QX9650.

But we have another problem. We have installed the 174.74 for Quad SLI 9800GX2 but it appears that there is only one card which is detected (same problem with SLI 8800GTS). The performances are the same as a single GTS, Rivatuner don't recognize more than one gpu.

We are using a Win XP 32bits, which OS is required to bench correctly this board?

Thanks a lot

You know i never tried P03R2 so i couldnt tell you, i can tell you P04 is amazing so far.

[jugeen]

i am waiting for xfx p04. if anyone has it pls share it.

Quad SLI does not work on xp
