Oh that sux indeed... well you shouldn't have any problem RMA'ing it :)
Good luck with the next one :thumbsup:

Does it do the same when running at stock speeds ?
Yes it's pretty much as audible (maybe SLIGHTLY less) even if I underclock it, got extra cooling over the card too but it doesn't appear to be a heat issue. It's just the typical noise of faulty caps when enough power running tru them, in some games and types of renderings the certain caps become more stressed so I'm sure it's just a faulty cap(s) on the card and been there from start. Wouldn't wanna replace it just cuz of that tho but yea I dunno what else to do that could garantuee I'd get that noise away.Quote:

I bought this card as a quick replacement for my rocksolid 6800GT since I needed something faster quickly since I'm going to the army in january so I want to use this new card as long as possible b4 but of course I always have this bad luck, now I just hope that next 100 card shipment arrives very soon to the site where I bought this one from or I could try and demand the money back and buy elsewhere in that case it takes more than a few days...
Sorry to hear that.
If you knew where the sound is coming from you could change the caps, but it's very hard to determine unfortunately.
I have a msi 7900GTO in order.. will it work @ 100% with a amd 3000+ clocked @ 2.7ghz and Gskill pc4400le @ 300mhz? i,m affraid if the cpu will bottleneck the videocard...
Subscribed :)
Subscribed.
I've tried penciling that left resistor (1k ohm standard)
Brought it down to 849 ohm and got 1.95vdimm instead of my default 1.81v
So YES people you can pencil the mem voltage :thumbsup:
I'm not going higher than 2.00v because I'm afraid the mem may be 'second rated' or behave 'strange' when you feed it "GTX voltage"... as in 2.12v... ;)
Thanks Garrett for the clear pics and results. :clap:
Don't you have 1.1ns on your GTO? Isn't the stock 2.0v and max 2.1v?
Are you going to change the mem timings too to match the tighter timings on the GTX?
The GTX does not have tighter timmings, it's the opposite, the GTO has the tighter setting for the RAM but the lower frequency.
Doh! :brick:Quote:

Hahahahaaaa.... YES! 12k single card... DONE!
With the core unmodded (1.4v) @ 715 and the memory @ 1.95v @ 1810Mhz :eek:
And by the way, I saw NO artifacts :) :thumbsup:
I haven't changed the timings of the memory :)

No it's not an approved driver, but I don't care much for that
What was mem OC before pencil actios (artefact free) ??Quote:

However in 3dmark I have yet to see 1 artifact :)
Mine start artefacting @ 840 (837 exactly)Quote:

My 1.1ns runs quite nice apparently, definitely NOT disappointed with this card... I don't know if 'real' GTX mem runs that much better ;) :)
Apparently OC works quite well with standard GTO BIOS and timmings.
In some cases, GTX clock are achieved with no modding at all, no extra voltage, nothing. Maybe if you're aiming for over 850MHz on the RAM, timmings could use a little adjustment.
Good going Garrett, really nice OC from a 250$ card ;)
What did you use for the pencil mod by the way ?
I assume you mean what pencil, right? It's the 8B versionQuote:

Yeah I really dig the price of this card, 242 euros :)
I remember last year November when a 7800GTX 512 was still 749 euros :eek:
Look what you get for 1/3 of that price now :D
Garret, I have exactly the same issue - running the artifact scan in ati tool shows a few little yellow dots (3 or 4). However, they are not detected as artifacts and i've not had any problems in any other benchmarks. If I drop my core clock down to sub 350mhz they don't appear, the higher over 350 I go the sooner they appear (it takes an hour at 600mhz for the dots to appear). Then again my GTO has a very poor core - I can only do 665mhz without it eventually overheating and artifacting / crashing. Messed about with the delta in bios and its not that - infact i've changed my delta to 75 for 650/650/725. Core temp gets to 67c after 30 mins and stays there. I think Im getting poor core contact, but can't risk taking the heatsink off incase I rip those memory pads..have nothing to replace them with. Memory is happy at 851mhz, so I've lucked out there though. From what I saw of the core oc increase in scores though I'd much rather have the ram clock well than the core. Course, both would be nice :).
Matt.
johnnyliu3377, have you benched the gtx vs the gto @ same clocks?
Would be interesting.
I don't understand why nvidia has released a 240€ card that is so similar to a +-450€ card. I can only think that it is to make way for their dx10 flagship 8800GTX?
Anyone gone from a 7900GT 700/900ish to 7900GTO?
must I pencil both resistors or just one of them???Quote:

I have had the same issue....
Remove and install again. Use 92.91 And not the 92.4 that is WHQL.. I had problems when tabbing in and out of source :)
