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

Reading through the ASUS forum S2E thread:

Looks like the data corruption when the FSB is raised from stock 333Mhz is very widespread on the ASUS Striker II Extreme... and I'm not seeing ghosts and tooth fairies benching/tweaking early into the morning!!

did they try ide drives?
im pretty sure its a sata issue, nvidia always had sata issues since nf3 iirc, with nf4 they were quite bad, especially with raid, with nf5 and nf6 they seemed fixed and only minor problems appeared, not with 7 it seems to be broken again... lets hope it can be fixed with a new bios...

And Saaya, I see it important (vcore, vdroop) mostly for us that do OC their cpus. I own an striker extreme 680i and sometimes you just hate that your CPU is stable at 1.36v but because it goes down to 1.34, you cannot keep it stable and that means by the time you get it stable, it will be getting a lot more energy than the neccesary when idle.

afaik it doesnt, it gets a slightly higher voltage, but the amps are very low in idle. its really just a psychological thing... afaik running a cpu under load with 1.4v is WAY WAY more stressfull for the cpu than running idle at 1.5v and low temps...

100% sure
i benched high FSB on both SATA and IDE drive
no difference
only difference is higher PCI Express frequency on IDE hence why i like using it more

so then pciE is still linked to SATA hmmmm
well its strange people are getting this much coruption.
yes, its normal to corrupt an os when running unstable mem speeds, but mind you, ive been booting and ocing in windows with setfsb to unstable speeds runnng orthos for weeks, and had the system freeze or reboot at least 200 times a day, and orthos or setfsb corrupted every 2 days or so, but i didnt have a corrupt windows xp install even after all this for 3 weeks or so...
so there is definately a higher corruption rate here than usual, even if you push the speeds too high and mem isnt stable.

i corrupted the drives on really tight timings past 2GHz on ref board and i know that it is RAM related 100%

the people that have coruption issues here are running in the 1600s to 1800s with cas7... from what ive seen they know what speed their mem is stable at in other boards, and id be surprised if its stable at lower speeds in 790...
i dont think its a mem problem, remember for fubarswe , afaik, the system was rockstable and passed stability tests for hours, but then eventually the system would slow down and then get corrupted. and the corruption vanished when he switched to an ide drive...
im pretty sure its a chipset thing...
it might be memory too, but... that wouldnt explain why that many people in this short time are having so severe corruption issues. if the memory is that unstable it causes corruption your usually way unstable and cant run any 3dmarks or other serious benchmarks besides superpi and everest.
if you push your system clocks up only benching everest or superpi, and then you blow your install, you wouldnt even post about it here would you?
its to be expected if you do that...
to me all those corruption issues happened unexpected, people thougth the system was stable but then suddenly the install went belly up...

i have the same problem now.
i only change the cpu today:
old: E6600, max FSB on STRIIEX = 490 FSB, 400 FSB rockstable all the time
new: E8500, more than 375 = no post
i don´t understand

hmmmm ask OBR for his settings, he got 45nm quads to 490fsb
what bios are you using and what settings?

Early reviews over the web show the 790i on par with X48, in some cases ahead, others just behind.

well, and x48 = x38, and x38 = p35 minus some pciE lanes so...
790 = roughly as fast as p35/x38/x48
from what ive seen 790 can reach slightly higher mem clocks with cas8 (~10%) and slightly higher fsb speeds (~10%) has slightly better mem performance at 1600 and 1800 memory speeds (~10%) but in all real world benchmarks and apps ive seen it surprisingly doesnt stick out compared to p35/x38/x48. for SLI 790 is the way to go, if you run singlecard or xfire it doesnt really matter if you go 790 or intel, the performance will be about the same.

to sum it up:
790 is interesting for people who want to see huge ddr3 clocks with cas8, people who want to run sli, people who want to get higher fsbs, and people who like nvidia chipsets/boards overall and prefer them over intel based boards.
now keep in mind this is all based on stuff i read and feedback i saw from a few dozen people and webistes, i havent actually played with a 790 board myself yet. i merely summed up what other people told me or posted on forums or reviews and websites about 790

Asus bios 507 really works, lol.
Viper Patriot 4 x 1GB Sticks, PVS32G1600LLK
Stock settings 1600MHz 7-7-7-18 @ 2T 1.8 VDimm Don't even think about running it there.
OverClock to 1800MHz 7-6-5-18 @ 1T 2.2 VDimm & wow, there is alot more.

very nice! i see you managed to get the bandwidth up!
