790i Ultra NVIDIA chipset - Still rockin' in 2015 / 2016 / 2017.. will it ever die? - Page 60

post #591 of 633
I bought the 2000mhz set of memory that was on fleebay today...

Time to break out ye-old 790ftw board:o


Looking back through some really old articles, the gtx280 was the single fastest card you could buy, but not worth the $$$ over the 4870. Everyone complained of how expensive the 280 was.

The gtx280 was $350 thumbsdownsmileyanim.gif

$350 doesn't even buy a 1070 these days...

Does anyone know where to find a reasonable priced qx9770?rolleyes.gif

I'm also interested in tracking down the waterblocks for the board.

Honestly I would just get an X5470 but yes it does require a board MOD, CPU mod and BIOS mod.

I had a QX9770 and it didn't overclock nearly as well as the X5470. YMMV but the 10x multiplier is high enough and runs well above 1600Mhz bus just fine wink.gif

You may have caught your 280 for $350.00, but that wasn't the norm. Here's a couple of screenshots with comparison info for the gtx260&260 a couple weeks after release, and also for the 1070,1070ti,&1080.(add about $50.00 onto the 1000 series for seller mark-up to be fairly accurate.) Not TOO bad for a 9 years difference. Look @ price differences in everything else over the last 9 years.

Hi everybody,

I'm trying to keep my 9-year old nvidia 790i Digital PWM 'competitive' for the next 5 years or so by going from 8GB ram to 16GB. Read of plenty of people successfully doing this via XFX p09 bios, cross-flashing w/ eVGA 790i's. However, I have yet to see anybody with the digital version pull this off.

Am currently using 2x4GB gSkill Sniper 1866 DDR3 @ 1667mhz @ 1.5v (When I add the other pair of the exact same 2x4GB ram, the system will boot up and then boot-loop, doesn't give me a chance to get into bios). Tried resetting CMOS, unlinking, setting to 1.65v & 1066mhz but still get the boot-looping issue. I also get a "4E" error according to the LED on the mobo itself. I've read from someone here that the digital version is not a reference board like the other 790i's, so now I'm thinking a cross-flash of the XFX P09 bios won't work (Did buy a backup BIOS chip in case I decided to try and something goes wrong though). I also could have sworn I've read of one person who has pulled this off w/ the digital board saying he had to "basterdize his 790i digital w/ an XFX bios..."

nVidia 790i digital pwm board
Intel x5470 @ 4.17ghz @ 1.28v
nVidia 1060 6GB

This is my first ever build and never thought I'd still be perfectly happy w/ it a decade later as it still runs the newest games like a champ. I don't want to build a new computer as I just spent $400 on a sexy custom 'Power Mac to PC' case for this machine.

Has anybody here heard of any 16GB success stories regarding the 790i Digital PWM mobo?

Thanks in advance.

Good question and very nice board you have there sir! drool.gif

Hope some of our friends here can help as far as 16GB. wink.gif


The memory controller on the chipset is really not very good.. adding 4 sticks (even slow ram) stresses the memory controller quite a bit. It usually means the chipset and/or memory will need some extra voltage.

DDR3 for this chipset is rated from 1.7v-2.0v.. it uses the very first DDR3 (1st gen) higher voltage memory. I would try setting your ram to 1.7v and bump your chipset voltage up a few notches. Place an additional fan blowing on your chipset, they tend to run very hot at times.

Also, be sure to run your memory in UNLINKED mode. Manually set it to 1066Mhz/1333Mhz (even if it is fast ram) as the memory controller becomes very picky with 4 dimms smile.gif

Good luck!

Thank you kindly sir, I appreciate your time and others here as well.

At one point I did have DDR3 1333 4x2GB (mismatched pairs) running unlinked at 1667mhz @ 1.5v for a few weeks on the machine (just putting that out there). There were occasional issues causing GPU driver crashes, probably due to mismatched ram so I went to 2x4GB and everything is okay again no more nvidia driver crashes.

Studying my MCP temps over the years I always stressed about the "high temps" that are indicated by the system itself, normally "reported" around 72c idle, then up to 92c under load which is where I get nervous because that's hot as hell if it's celcius (but my system NEVER gets that hot as I'm feeling around the system for the source of this "near boiling" heat). So I was concerned when you speak of raising voltages further, HOWEVER...

I literally just read up on MCP (Southbridge) temps and someone said that there's a "glitch" to temp sensors in many cases when it comes specifically to MCP temp readings, where it's "locked" to providing readings in fahrenheit but will falsely say celcius. So in my motherboard's case that it reports 72c, it actually means 72 fahrenheit or 22.2 celsius!!!!! Now this makes more perfect sense to me and I can finally rest easy after 9-years of stressing about the high MCP temps hahaha. Not only that, but the MCP temp reading scare has kept me from pursuing overclocks beyond 25% all these years.

With that said, the x5470 idles at 47c and full loads at 82c which seems pretty hot so I don't really want to push for a further overclock on air.

Also seen your bios settings for GTLref being "default" vs. "auto". I do not have 'default' as an option so you see mine's all set to +00 instead of 'auto' wink.gif

So when you say "bump your chipset voltage up few notches" which one of these options in the picture I've enclosed controls the 'chipset voltage'?

Nforce SPP wink.gif

Very nice! thumb.gif
post #600 of 633
Thank you again sir.

I just tried upping the voltage notch by notch on the nForce SPP but still bootlooping issue w/ no ability to get into bios.

There isn't a whole lot of headroom here for adding voltage to the SPP (see below).

Ram is unlinked, 1067mhz @ 1.7v

Nforce SPP was bumped up to max one step up at a time, everything else left to auto.


Perhaps something else needs more voltage...
