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

[GAR]

I just tried setting the GTL to +25 and FSB from 1.3-1.45 all failed with no success, im about to give up, even tho i dont want to, im really dissapointed at this.

Chill GAR,

You and many others are having the same problem, I did have it but I solved it with some methodical GTL + VTT(FSBV) adjustments. Go dig around the EVGA Forums and check the last page of the 790i corruption thread here for starters. Takes some patience but its the only way to beat the issue.

Since when has PRIME/OCCT/Orthos been the sole measure of a systems stability... I know it's how most people test but not me, I have to engineer 24/7 commercially warrantiable OCs and I ALWAYS do testing with Video decoding and other things to stress FSB under smaller loads aswell.

Can you give me your settings for 450fsb......lemme give it another shot before i go to frys tommorow.......if i cant get this thing stable, im going to frys tommorow and this thing is going on ebay for 250 bucks free shipping.

Every chip is different, yours is quite different being 45nm n all.

I use 1.20VTT & +25mv for all GTL lanes @ 444FSB, no "hangs" in over a week or ever at these settings.

I saw some others had success w/45nm using +15mv for their GTLs so I would start there. +15 - +25mv for all your lanes w/ VTT set as low as it'll go for you, 1.1V i think right?.. if it hangs goto 1.15VTT and 1.20VTT.

You can test stability with any 1080P H264 content you may have or HD-DVD/Blu-Ray Rips.

Just relax though m8, the problem is fixable with just abit of tweaking and patience.

What is the best TEMP readings monitor out there for the S2E? I have been using Core Temps 0.98 and Real Temp 2.41. But both are off huge is degrees?

Thanks...

Bump on the question above


MMmm where to start? For starters when I had my Q6600 GO chip in the S2E I had no problems pushing a FSB @ 1800 @ a 2:1 ratio with my memory. Or even a 1700FSB, 2:1 as well using BIOS 0511. Now I throw in my QX9650 and I am getting freaking memory dumps like crazy. I can not even stay stable at any settings? I am back stock for now.. Just wondering why is this happening to a 1K CPU and not my $200.00 CPU? I have a idea for ASUS why don't they PAY US to work out all of there kinks on the S2E and give us our boards for FREE. Note to self never ever buy a new mobo with a new chipset, if so plan on being the ginnie pig with many headaches..

it doesn't help the 790i chipset plagued by untuned GTLREFs that the C0 stepping 45nm quads have a GTL related errata which hampers OC'ability in the first place.

I feel your paind, im going to stick with this board for one more bios release, if nothing stable is produced im going to swicth to intel, no other choice, everytime we get a new nvidia chipset, a million problems come out, and not small ones, HUGE ones.

Hmm, everything looks absolutely stable here, I am satisfied completely.

I had the same issues with OCZ memory (DDR-3 12800 Platinum, not EB) before, couldn't even run it at the stock settings and was about to give up, like you do.
Everything became to be much better with the memory replacement and now it is fine with 04 BIOS.
In your case it also can be a memory hole - I am getting such things at 400 MHz and 450MHz exact numbers somehow ...

hi,
i search a pencil mod for evga 790i,
the vdrop is 0.7 0.9 v
HELP

[MateoTTR]

Hi there,
I have drastically improved stability of my s2e. I installed Vista 64bit SP1 a week ago, and no corruption so far (I test every day).
I use the following bios settings:
fsb qdr ddr at 1800 linked & synched
CPU multi x8 (3.6 GHz)
RAM timings 8-7-6-20 2T P1/P2: enabled
Voltages:
Vcore 1.325V in bios
LLC enabled
PLL auto
VTT 1.44V
VDimm 2.0V
NB 1.66V
SB 1.6V
the rest is on auto.

Prime95 & memtest86+ are stable for 10+ hours.
I had very frequent lockups in vista while playing games or just idling on the desktop after 1-2 hours of up time.
I changed my RAM from 1T to 2T, and it really helped a whole lot.

Now I still get lockups, but it's very rare and hard to reproduce... Usually I get it when there is a joint stressed activity of HDD, CPU & RAM.
It can happen sometimes when loading a level in a game, for instance crysis or company of heroes, in the middle of the progress bar when all textures and stuff are loaded.

Do you guys have any clue what I could test?
I have the feeling the freeze can only occur if there is a lot of disk activity. It does not happen during video playback or within a game like it is the case for others.
What would you suggest:
- increase SB voltage: 1.65 or 1.7
- increase frequency for PCI-e and MCP<->SPP
- loosen the ram timing further
- play with VTT volts and GTL REF

Please help !

GAR, are you having those issues at stock speed? or oced?

[slim142]

I think GAR is having those issues when OC @ 450mhz FSB, and I also think he should keep his settings at stock for the time being.

Wow, is almost end of april and I gotta decide what board Im gonna end up getting... I dont want to deal with corruptions, BSoDs and lock ups.

450FSB, but this to me is more related to the memory controller on the NB, its got some weird holes........also high fsb around 463, with mem at 925 corrupted my steam, i had to reinstall everything.....the corruption is still there and i dont feel safe doing anything on this board knowing that it may give out at anytime.......one day my settings were good, and next day they were bad so im confused with this board at this time.

[Broly]

I love my S2E. It tunes all your settings.
Running bios 0601 I can hit 4000 MHZ no problem on all auto, just 10 multi and 400 fsb and it's behaving well!

[Big Myke]

0601.bin got removed from Asus' ftp. Interesting.

[QuadSLI]

I just Ordered the Striker2 Extreme with 4gig of OCZ 1600EB RAM

hope I didnt just make a mistake

Im about to place order on the RAM FOr SIIE. Is that true only the black Slot support 1800+. So i need to order 2x2G instead of 4 sticks?

Option
1) OCZ - 4GB OCZ DDR3 PC3-12800 Platinum EB XTC (7-6-6)
2) G.Skill - 4GB G.Skill HZ Series DDR3 CL7-7-7-18
3) Patriot - Viper 4GB PVS34G1600LLK CL7-7-7-20
4) Corsair - XMS3 DHX 4GB DDR3 1600 TWIN3X4096-1600C7DHX

0601.bin got removed from Asus' ftp. Interesting.

0601.bin works 50/50 when you flash the bios, worked good on 2nd Striker but almost failed 3rd, goodthing it rebooted into bios with half the stuff missing but loaded again & all was good...
I'm sure its causing problems flashing...

[X2beach]

Starting to think I should have order this board.. maybe I need to cancel my order, and get Asus X48 mobo

Don't get me wrong Hardcase, I'm running stable with 0601.bin since day one that I flashed it. I just was observing Asus' FTP and the 0601 bios was removed today.

0601 overclocks badly.

[TheHardCase]

Don't get me wrong Hardcase, I'm running stable with 0601.bin since day one that I flashed it. I just was observing Asus' FTP and the 0601 bios was removed today.

Don't forget I lost my first 0601 bios, it failed install & I had to RMA board.
I'm not the only one that failed loading 0601, I almost lost the 3rd board to it again, got lucky on that one...
I'm still testing 0601 but I'm not sure if it's as good as 0507.
I will keep it updated for sure...

I hope by the time I have my money ready, all this problems are solved.
BTW, I have the same question as QuadSLI, are the black slots the only ones that can run higher than 1600mhz FSB???
Because I just got 2Gbs RAM kit and I would like to go to 4 gigs one day...

The Black Slots do 1801 and up.

On the eVGA and XFX (reference boards) use the black slots, on the SIIE use the blue slots for 1800+.

[RealTelstar]

Anybody knows when the DFI and Foxconn will release their 790i boards?

[Broly]

I am pretty sure the S2E has 4 high bandwidth slots, not just 2.
