Factory OC'ed 7800GTs artifacts

[Nobuo]

Just got my Leadtek 7800gt yesterday. Artifacts like crazy with out of the box settings. As far as I know, there is no updated BIOS from Leadtek to fix this (yet). I'm annoyed, and I'm probably gonna have to RMA the card :|

Thanks Rahzel. yeah, weve discussed this before. i was still worried, since ive read a few people who flashed to new bios and still had problems. however, i suppose those may just be a bad card.

you had artifacting with your evga that the new bios fixed right?? still no trouble?

any idea if the 7800gtx had artifacting/bios issues as well. ive mostly heard of it with the GT.

yes. still no trouble.

i thought i answered you already.

thanks... i know, just checkin if it was still runnin good, never know. good to hear.

that sucks... and its not an evga. is it overclocked? i wonder if the leadtek bios has a delta. hmmm.

I don't like it when OEMs take it upon themselves to factory overclock the cards. As far as I'm concerned those cards are running out of spec and I flash the BIOS with nVidia's reference version to get things back to normal.

That makes no sense whatsoever.

In the fact that it makes your card slower and voids your warranty, I am of the mind that it doesn't make much sense.

Thank you.

And you enjoy your 50 MHz overclock which adds a glorious 17 extra points to 3DMark scores.

An overclocked 7800 GT is almost as fast as a 7800 GTX. You can see this in any 7800 GT CO review. So basically you're arguing that there's a 17 point difference in performance in 3DMark between a stock 7800 GT and a stock 7800 GTX. You're wrong, and as blckgrffn stated, your moral victory is voiding your warranty at the same time.

The EVGA 7800GT comes slightly overclocked at 445MHz (core) and 1070MHz (RAM) which may explain why so many EVGA 7800GTs seem to have artifact issues.

I just want a working 7800GT. I only paid ~$272 (taking into account a $40 MIR, a "free" EVGA mobo, and shipping cost 1 way to RMA the first card) for a 7800GT, so I'll still be very content PROVIDED the second RMA'd replacement works okay.

I'm starting to think that I may be one of the lucky ones. I got an EVGA 7800GT from the first shipment in August (with the old bios with the geometric clock up 40) and have never had any artifacting problems. Also, I have the stock cooler on and my case is relatively quiet. Even with the old bios, Coolbits auto-detects it at 488 Core, so does anybody here think that i can get 500~520ish if I updated the bios to remove the geometric clock? Most guys on the evga forums have gained 40 or so mhz from the update. I'm thinking that I got really lucky and got an exceptional core.

curious.. why would you do that? wouldn't it be easier to just purchase one that had factory specs? certainly seems there are more avail @ stock speeds than factory overclocked ones...

no, i already explained why EVGA 7800 GT's get artifacts; many times...

if you get artifacts, go to the EVGA message boards. Go to the Geforce 7 series boards and theres a sticky with a BIOS update.

AGAIN, the reason EVGA 7800 GT's get artifacts is because ONLY EVGA have a geometric delta clock of 40mhz. It adds 40mhz to the core running 3D apps. All the other 7800 GT's have it set to 0. The people who were getting artifacts with EVGA cards were the people who couldnt handle their core at 485mhz. If your card can handle 485mhz+, then you wont get artifacts with the Rev.1 BIOS.

then again, EVGA is probably shipping their cards with the Rev.2 BIOS now, so you might get a card without the geo delta clock.

EVGA made a major blunder with their oc'ed 7800GTs.
Since the newer bios reduced the geometric delta (wth is that) clock, it means that the entire model is defective at factory overclocked speeds and testing was subpar.

The nVidia 7 series cards have key overclocking points that give you noticable boosts.

They can do if they overclock.

In the fact that it makes your card slower

Which is often not noticeable but it's more likely to be more stable.

and voids your warranty,

And overclocking doesn't? Granted an OEM OC might not but most people don't stop there.

An overclocked 7800 GT is almost as fast as a 7800 GTX.

Just because an OEM overclocks the card out of the factory it doesn't mean it's stable.

your moral victory is voiding your warranty at the same time.

And overclocking isn't?

curious.. why would you do that?

Because vendors like MSI like to ship OC'ed cards which unfortunately leaves them unstable right out of the box. I mean in this thread there's another example of EVGA having the same problem.

certainly seems there are more avail @ stock speeds than factory overclocked ones.

Actually most of them are overclocked and hence nVidia's reference BIOS is your only guarantee that things are running exactly like they should be.

All of this is moot if you get a factory oc'd card, get 5-10% better performance in some cases (Doom3, for example loves the oc'd cards, check the anandtech review of the chaintech card clocked at just 450/something I can't remember) and have the warranty to back it. And I have zero stability problems, thank you, and everyone who oc's their EVGA's does NOT void their warranty, but then again you are also free to use whatever bios you like

I got my new card back from the RMA and it works nicely.

Leadtek 7800GT Extreme.

I still would have gotten a regular version.

Factory overclocking is great...faster of course is better.... BUT NOT IF IT SACRIFICES STABILITY OR CAUSES CORRUPTION. This should be carefully tested at the factory before releasing. It seems that quality control was sacrificed to sell more cards faster simply because of higher clock speed numbers. sounds like a marketing ploy and a rush to market before extensive stability testing.

most of the artifact trouble has seemed to come from the evga cards because of the added delta, like rahzel has stated. removing the delta from the bios has seemed to solve evga problems. however, its looking like not only evga is having trouble with corruption/artifacts. Factory overclocked cards from other makers are popping up with artifacts as well. Some cards just seem to be able to handle the higher clocks better than others. In my opinion, only the cards that have been tested to be able to handle the oc and still be stable, should be sold as oc cards. then, of course they would be considerably more expensive...there is the problem. so, they kick up the oc numbers, to sell more cards, keep prices low and hope they sell alot more than they get returned. either that or the makers are clueless, didnt test the cards properly or have pitiful quality control.

If your gonna sell a factory overclocked card....make sure it can run stable overclocked! If not, sell em at stock speed and let the people who want to risk overclocking do it themselves. Just makes sense to me.
