790 corruption issues?

[5010]

I have a theory that the data corruption is caused by bad FSB Voltage, usually too much combined with possibly bad GTLREF's, with increased traffic on the memory controller/NB from higher FSB and tighter RAM timings. 0 & 1's are getting back to the NB from the CPU a little confused and some of those are being written to the HDD.....

Got my reasons to theorize this

[slim142]

So I guess is a bad time to buy a 790i?

Unless you're a hardware maniac, I'd say stay away for now until further info is released, and hopefully a fix or cause is found.

My Striker II Extreme should be here tomorrow they told me earlier on the phone

you hardware maniac you

[slim142]

Hopefully by the end of the month everything might be solved.

Is not that Im a hardware maniac, but I have hardware to BURN BABY BURN!!!

Well if anybody knows what setup was kinping using on his 790i and could please tell me, I would really appreciate.

[DaMulta]

EVGA I belive.

OCZ 2x1 GB DDR3-1600 7-7-7-20, working well in eVga 790i¿?
which memory you recommend with good value ?
I not found memories List supported for this mobo.....Someone knows?

Thankss bros!

I am extremely close to ordering one of these, but the RAM I want is impossible to find so I havent yet.
Maybe its not meant to be?!!??!

pretty much, at least not for the next 4 months.

Just get a cheap D9GTR 2GB kit to play with in the mean time.

hmmm i emailed gary from anandtech but didnt get a reply yet...
ask xt0m, he had 2 hdds die on him, he should be able to give you some details.
if he tells you interesting details please post them here

I guess I need to check the spam folder.

"We have two 74GB Raptors that are basically dead, they will power up but cannot be low-level formatted. The WD 250GB drive basically had the same problem. The two 500GB Samsungs will power up and repeat a click-clack pattern. The Samsungs have been returned for analysis as will the 74GB Raptors.

I am getting ready to do the same for a pair of 150GB Raptors that I wrote off in December. However, those drives failed (no longer accessible) during RAID testing on the 780i board (usually I yell at myself when that happens as I have had far too many RAID 0 arrays drop a drive over the years). I did not think much of it until we started having these data corruption problems over the past six weeks.

Between Kris, Raja, and I there have probably been around 14~16 image reloads the past six weeks after overclocking. We fully except to trash the OS when exploring the boundaries of memory/fsb rates, but it might happen once or twice a month at best and is not limited to NVIDIA chipsets. However, all of these failures have been on the 780i/790i boards and we were not really pushing the systems except for two times when the drives failed or the images were corrupted.

The frustrating/perplexing problem is that the 790i testing with Kris resulted in some of the best overclocks we have ever experienced and they were 100% stable. We changed the settings to a normal overclock at 400FSB/1600 DDR3 and the images are corrupted or the drives went south. It is not repeatable at a given setting. We have seen results like ours in various forums so there is something amiss here, just trying to find it right now.

In all cases, we have had the memory settings set at something other than stock/default. I am still working with Derek as he has experienced several data corruption problems during SLI testing the past couple of weeks. I did not mention that until we figure out if his problems are related to ours."

data corrupted on IDE HDD on reference board, but after many days of playing ... worst is very bad ocing possibilities of this mobo ...

[Blacklash]

Has anyone approached nVidia so they can start a proper investigation into this?

In any case, I alerted a focus group member about this thread. Hopefully, it will get reviewed as well as the Anand article.

[saaya]

could you guys PLEASE stop posting links to that anandtech article?
there must be 5 people who already posted a link there

slim142, yeah sure you can get good ariflow in a big case too, but you need more fans and itll prolly end up noisier. i prefer a small case... its easier to create propper airlfow in there. but then again, i dont use any case whatsoever for... 6 years?

[slim142]

Oh well, I just decided to go for the Armor because of the space but I would also consider the P182 as a nice 2nd option

[Lu(ky]

Hey slim142 did you get the Asus S2E yet? Newgg is having a -$40.00 off coupon plus free shipping a $50.00 savings for a 24-hour sale...

so its not just the wd drives suffering from problems, thanks, thats good to hear. well, NOT, but you get what i mean

so you had 2 raptors and two samsung drives fail? or even more?

yeah i remember raja having a good time with crysis
i recommended him to use ghost since i think he didnt use it by then cause he didnt have that many corruption issues before.
it def makes your life THAT much easier
well yes, thats the weird thing, isnt it? on intel and amd chipsets i blow a partition after 300-3000 boots at unstable speeds id say, and even then most of the time you can repair the install with the console or by replacing some files. i wonder if amd and intel and other chipset makers use some special ECC like technique to prevent corruption at unstable speeds or whether nvidia is maybe using bigger cashes/buffers which then dont get flushed if something goes wrong and bigger chunks of data are missing or corrupt.

The frustrating/perplexing problem is that the 790i testing with Kris resulted in some of the best overclocks we have ever experienced and they were 100% stable. We changed the settings to a normal overclock at 400FSB/1600 DDR3 and the images are corrupted or the drives went south. It is not repeatable at a given setting.

well thats the thing with nvidia chipsets... everybody who spent enough time with one or a few boards knows about this... from what i heard this inconsistency in something working once and then not working and suddenly working fine again is typical for nvidia chipsets ever since the 5 series. i really wonder what it could be, i can only imagine that some plls or some dividers lock every time the chipset is configured and initialized and for some reason it doesnt always happen the same way every time the chipset is reset.

but the bizarre thing really is that those problems happen at 1600, which is exactly where you would expect everything to work fine, as thats what you want everybody to run. if it would corrupt or give you a hard time at 1700, well, thats above the spec, too bad, we are working on it but for the moment only 1600 is stable. that would be fair enough. but the memory failing at 1600 while much higher speeds work fine is... odd...

i first thought maybe nvidia tuned the performance so at 1600 its tweaked really tight to win reviews and be fast at stock speeds, but if that would be the case with all those problems people are having id have expected them to release a relaxed stable bios by now. so it seems to be something else, or nvidia is really stubborn and doesnt want to losen timings to give up some extra performance

In all cases, we have had the memory settings set at something other than stock/default. I am still working with Derek as he has experienced several data corruption problems during SLI testing the past couple of weeks. I did not mention that until we figure out if his problems are related to ours."

well overall it seems quality control is falling apart industry wise... at least thats the impression i got over the past 5-10 years :/

which is really too bad... there are so many power users who are actually willing to BE abused as beta testers from manufacturers, and most users are more than happy to work with the manufacturers on a solution, but 95% of the feedback seems to be ignored or takes a month to reach the right people.

This is exactly what happened to the S2E that I RMAed. Memtest was hanging (3 consecutive times)RAM@1600 unlinked with 1333 QDR(default). Guess what, same RAM, same settings, I tried the same thing again after some time playing around with the board, it worked fine . It was also randomly rebooting for some reason, while windows was idle with no to moderate OC and one time it rebooted when I was in the BIOS. I also eliminated the possibilty of a bad PSU.Hope my replacement board which should be here tomorrow is much better.

[TheHardCase]

Ehh Saaya, I still can't get anything to happen like it did the first time.
I'm starting to wonder about 1600MHz, I changed out the ram to 1800Mhz & no problems at all, I'm definitely going to say there is a problem at 1600MHz corruption issue.

[BenchZowner]

Currently installing Windows at 400MHz FSB and the RAM @ DDR3-1800.
I'll do some testing later on, don't know how many tests...as I'm finishing a review simultaneously

[Delirious.]

I don't know if any of you know this but the Q6600 doesn't run over 1630 on the 790i. No posts whatsoever at any settings. Check out the EVGA forums for more info if you are having problems. It might be a definate QDR 1600 problem.

[GAR]

we need the P03R2 bios, if anyone has it please share.
