Anyone here with a vmodded GTS or better two on a 790i board? I have some strange things going on here..

I'm 100% sure that both GTS are set to 1.333V idle before i put them on to the XFX board(tested on P35 and AMD 790FX), but now i measure just 1.118V in idle on both cards.. When i disable the mods then i measure just 0.996V in idle, thats less then the default specification for the GTS.

Hope someone can help me here!

Edit: Problem was a empty battery on my one DMM..

Many problems with your XFX 790i card? Thinking about bying the same one my self you see.

Someone who knows how the Striker II 790i bord works? More stable than the 780i version?

What about the temperatures?

Is your problem resolved then??

What online stores are selling this board in the usa?

I have maped FSB holes on nF680/780 Asus Striker, Striker II Formula but on this nf790 there are not usual holes like before (400mhz for example) , i can set any FSB without problem ..... my OC is 550MHz without holes, but i am testing only 45nm cpus ... 65nm Kensfield cannot to be overclocked, in BIOS is some problem ...

Anyone else have this problem with Kentsfield? Has this been fixed? Thanks.

Is your problem resolved then??

Yeah. Thanks a lot for your responce anyway! My one GTS just suck.. Does only 848MHz..

Hi

Is anyone running 4Gb DDR3 1800Mhz on this board. Have 2Gb OCZ 1800 with asus 790i ultra, but thought read somewhere is problem with 4X1Gb modules @1800??!!

The 790i only supports 1801+ in the two black slots. IOW only two sticks of any speed over 1800 are supported.

I'm currently having a lot of trouble getting the Striker II Extreme to run with any FSB overclock over 350... the system passes all the torture tests with flying colours, 7+ hours ORTHOS blend, 2 hours OCCT Mix. But then the system randomly shuts down, BSOD, programs randomly terminates, and especially likely when running 3DMark06, PCMark Vantage and shutting down the PC. Latest BIOS and relaxing the memory timing don't help, raising all voltages made it even worse... Very disappointed.

I have since ordered a EVGA 790i Ultra as replacement until better BIOS fix the Asus Mobo..

Question,
My online store have got a few evga 790i in stock tonite! They also have the Asus 790i in stock soon. Can't make up my mind about the two, same price on the boards. Need some help making a decision.
Thanks

evga 790i all the way!!!!

But check out this blog post from FCG over at anandtech: 500 fsb stable on yorkfield, Asus 790i (plus 2000 mhz with 8gb of ram).

what the heck
are you sure it updated properly >> try clearing cmos and battery for a few hours

OBR was ing all the way to eternity until he flashed to the latest bios and then everything improved enormously

Just had a read through... The results seem mighty impressive. However until they post their BIOS settings and I'm able to duplicate their results, I remain skeptical to the Asus S2E.

OBR was ing all the way to eternity until he flashed to the latest bios and then everything improved enormously

I am using the latest BIOS I could find, version 0507, and at stock setting it is 100% stable. I am reluctant to reset the CMOS, as every time I do that I have to disassemble my watercooling, replace my QX9650 with a Core2Duo, take out a stick of ram just for the system to POST and increase the ram voltage. And trust me, I have done it enough times to streamline the whole process.

The problem I find is that everywhere people are reporting that their reference 790i are overclocking demons, and very little voltage has to be raised to achieve 450-500Mhz FSB, where most are set to AUTO.

That is VERY far from what the Asus S2E is doing... after you run hours of torture tests, are are happy with its stability, it BSOD on you launching a web browser, a game, or restarting the PC.

I am currently running the system with 333FSB, 12x Multi, and 909 Mem. 100% stable.

[dinos22]

that's shocking (are you sure you are not over tightening your waterblock) >> talking about your bios clearing issues aside from other stuff eek

i don't think you'll have those issues with reference boards to be honest unless you are overtightening or something

you also don't need to be too clever when OCing as nvidia engineers have some some good ground work to improve OCing and make it very easy .> leave volts at auto (only set vcore/vdimm) and let it rip

Thats what I hope with the EVGA I've ordered, and the waterblock is spring pressured and with back plate so not much stress on the Mobo.

On auto was the first thing I did on the Asus board reading all those posts on how its ability to control the volts is awsome, but no go on the Asus. The pinnicle of its stability was with upped Core/vdimm and VTT, with the rest on auto. Hope the EVGA will be much better in that reguard.

@ Eternal, are you sure it's not your RAM. I kinda vividly remember seeing some post about 790i and cellshocks not working well together here @ XS.

even after cmos clear though

Don't take it the wrong way me quoting myself, but here it is;

I am using the latest BIOS I could find, version 0507, and at stock setting it is 100% stable...

....I am currently running the system with 333FSB, 12x Multi, and 909 Mem. 100% stable.

Also if CellShock don't work with 790i... it will cause havoc here in Xtremesys, as from what I can see almost 1 in 3 DDR3 memory here are CellShock branded.


edit: Also note that the board is absolutely flawless. At its default settings, that is. It is another story once overclocked.

[canislupy]

The problem is that it will not post the cellshock at all, the workaround (this was for the EVGA 790i anyway, dunno about the Asus) is to use crap DDR3 RAM, POST, set RAM volts up to cellshock supported, then swap in cellshock. I get my crucial crap kit tomorrow to try for myself. Sonofander was the one who is running the cellshock withe the EVGA, and IIRC he is running it at 500MHz FSB.

[dinos22]

must be something in cellshock SPD cause i have no issues with corsairs

Oh yeah I also have that problem after a CMOS reset, as mentioned previously. However once the voltage is set the memory runs flawlessly.

[eternal_fantasy]

Exactly. In the CellShock the SPD is set to 1800Mhz 8-7-6-21, 1.5V...

edit typo

well that makes sense now heheheh

does SPD tool work with DDR3?
you could edit the timings to 9-9-9-24

[canislupy]

Those wacky Germans....

[jcniest5]

Does anybody know if PC3-8500 (1066) memory work on the 790i board or do I really have to get PC3-1333 or better?

[eternal_fantasy]

well that makes sense now heheheh

Don't know, as it wont run under Vista 64-bit
