Hello,

Just bought ASUS 7900GS (non-TOP) 256/256 clocked at 450/1320 MHz.

Pulled out my older 5950_Ultra 128mb/256bit from the AGP slot, uninstalled the drivers and then pulled in the 7900GS into the PCI-X slot, installed the ASUS drivers and utilities.

When i launched the 3dmark03 benchmarks, the pixel-shader scenes got very very very highly artifacted. Collected 10K+ points...

Downloaded and updated the newest system bios 1.70, via chipset pack 510a, and then the newest ASUS drivers 94.42(or kinda that), and the artifatcs are STILL highly visible... Tried with stock CPU, and again with OC'ed..

System specs:

*Asrock (cheaper division of ASUS) 4CoreDual-VSTA Mobo, based on VIA PT880PRO/Ultra
*E4300 @ 2.40 (1066)
*1GB PQI DDR2-667 CL5
*Creative SB Live! 24bit 7.1
*Leadtek Winfast 2000xp TV-tuner
*Samsung T166 250Gb SATA2 HDD
*Win XP SP2

Please share your ideas :)

Yes yes, PCI-E. It had a dual adaptor from 2 standard molex to 1 pci-e power connection. I used 2 different rails from the PSU to connect it. And the power is sufficient = 550W.

have installed VISTA and it ran flawlessly, not a single glitch ! Collected 16500+ points with CD-Supplied drivers 100.xx

then had an idea of installing xp again, and even a fresh install gave the stupid artifacts.. then decided it's the asus enchanced drivers, but no - uninstalled all asus stuff, and it still gives shit with nvidia drivers 93.xx

guess I'll have to stick with Vista... probably the time has come.. :/

Done more testing with Vista and newest 158.xx drivers, collected 16655 points.. Although 3dmark03 gives 0 artifacts, the screen frequently flickers and returns error "video driver recovered successfully".. so I guess it's DOA...

I'll probably have to bring it to the retailer and request a RMA...

Thanx ouch1, but these are expensive, and i think it has enough ampers..

I had my VGA replaced by the retailer - no result...

The main idea, as I have read across the web, is the world-famous VIA->NVIDIA issue, where PT880 Ultra does not work with 7800/7900 cards...

I'll have to ask my retailer to replace the mobo with one of the similar-priced...

As of cheap ones, I like ASUS P5PL2-E:
it has 5.1 HD audio, PCI-X x16 support, FSB 1066 (good for OC'ing my CPU) and is inexpensive.

Suggestions?

That is probably a dodgy psu btw. I am trying to get a pic of the label, but I havent found one yet. Maybe you could take a photo of it and post it here...?

EDIT: q-tech are tier 5 on the xtremesystems rankings, which gives me the impression that your psu is low quality.

Of course these rankings are not based on heaps of testing, but are good for a general idea as to how good or bad a psu brand (or model) is.

Well IMHO I recommend getting a refund on the Q-tec one and getting a good Tier-3 or better PSU with at least 2 12V rails with 22A each. This will make you system much more stable, and it will supply the proper power to your video card.

I am running my rig ( X2 4600+, 8800GTS 640MB, BFG nForce 590 SLI mobo, 2GB DDR2 800MHz, and lots of other goodies ) on this:
Thermaltake Purepower 500W
And have not had a single problem. But it also has 29A combines from both 12V rails. And I paid $75 for it 1.5 years ago.

If you look around a lil bit you can find good deals like these:
Antec NeoPower NeoHE 550 ATX12V 550W Power Supply - Retail $69 ($109 -$40 mail in rebate)
ENERMAX EG565AX-VEFMA2.0-SLI ATX12V Ver.2.0 535W Power Supply - Retail $89.99
ENERMAX Whisper II EG565P-VE FMA(24P) ATX12V Ver 2.0 535W Power Supply - Retail $79
All 3 of the above support both 110V and 220V AC current so they should work outside of the US without a problem.

And just remember when it comes to power supplies good quality means higher prices. 5 years ago I paid $100 for a 300W enermax power supply. So prices do also come down eventually.

Well in Lithuania, outside US a refund is not an easy option - you have to bring an _accidentally_ failed PSU, with no warranty void to get a refund... I bought it about 3 months ago, so the warranty exists, but..
it is virtually impossible to get a refund as the warranty is void as soon as it gets damaged..

This is Lithuania: EU, but still half a 3rd world, so they don't import these brands from your list..

The only worth attention, but much more expensive than I can afford ~ $70 in ur money would be this one:


ZM460B-APS ZALMAN 460W ATX PSU, ULTRA SILENT

The Zalman should work well for you. It has a combined 34A on the 12V rails. If I were you I would give that a shot and see if it takes care of your problem.

Well... I can't afford just buying another PSU, which is even more expensive...

If my corrent Q-tec "suddenly" died, that would be an option to request a model change to a better one with additional payment, which I could try to affrod..

But that's probably not that easy...

Well you could always contact the retailer you purchased the system through and demand that they replace it since it is obviously defective. They should replace it just to make you happy. And especially since you have already delt with them about this issue I doubt they will have a problem swapping it out.

When my nvidia drivers get corrupt it artifacts everywhere, also happened on my old board if i installed ntune, removing old drivers completely using the removal info @ http://www.tweakguides.com in the nvidia guide and installing the new ones solves it for me every time.

It may not be your problem but it happens to me regularly when i update drivers

Custom PC (UK) did a review with test equipment a while ago, and the Q-TEC was terrible! If you read the label on yours, you will see it say "PEAK Power" 20A. It DOESN'T say what max continuous is. I suspect the artifacts are when the graphics card is pulling max power. If that PSU fails, it may well take other components with it. f you are prepared to pay big money for a top CPU and graphics card, please DON'T skimp on the PSU!! You DO get what you pay for.

Mike.
