well I've called the retail and told them about i get random freezes, at stock and white pixels (only sometimes). they said once they receive it they'll test it and if they see it doing the same thing they'll replace it, if not they won't replace it. the person was trying to blame my PSU. i know 100% it's nothing to do with that. has my 6990 works on it perfectly

i fear now when they receive it and test it, they'll make some stupid reason up and say it's working and blame my pc.

one other thing why does the 200 series have vdrop?

The PSU is a frequent early fob off, that won't be the issue with your PSU.
 
well after playing around with it, I've got it stable at stock so far.....

and max stable OC i can get is 1110/1450 with +100 mv, which is pretty poor?

it seems the vdroop on this card is around 100 - 120 mv has the stock voltage is 1.250v but droops to about 1.125 - 1.158v under full load. why has amd gone with using this voltage system?

Is it not stable at stock clocks with stock volts?
If it's not then send it back. Don't settle for less.

it seems to be stable at stock clocks with stock volts now with driver 14.7 :confused:.

but I've contacted the retail again today and told them that it seems stable a stock now, and they said if the issue comes back or becomes worse then just to contact them again to get it sent back even after the 14 days. he also said i'm doing the right thing because if they get the card back and they test it but couldn't find a issue, they would charged me.

i know this card is poor but i guess i'll have to wait till it degrades more.

i think I've sorted it.

i have downgraded the vbios and the voltage seems a lot more stable and lower temps.

now i can get the core to 1100 with only +30mv.

i'll do more testing.
 
this is when playing crysis 2 for 10min~

well the retail confirms the card was fault even tho looking at the above link it suggests the vrm temp sensors are wrong.

anyway i'll be receiving a replacement tomorrow.
 
I don't get how / why AIB's have to mess about with the PCB's and get it so wrong????

This is not the first Asus problem and they are not the only AIB to have ##### up their deign.

The reference PCB design seems fine, no issues with it and it seems to be the one that's best for overclocking, some people say its better than any AIB PCB.

So what are AIB's doing? is it just incompetence or are some just not bothering with a Reference PCB as a penny pinching exercise? IE because they are higher quality.

I seem to remember reading somewhere about Asus removing AMD's own choice in top quality reference Voltage management chip, only to replace it with an inferior one.

what gets me is i will have no way of really knowing what the vrm temps are really at. and also these Asus 290X DirectCU II OC cards are meant for overclocking has they have full unlocked voltage, and no throttling.

so how can people OC them safety if they don't know the real vrm temps

I guess they just go off the temps they can read, and the fact that if they get artifacting they know they've gone too far :(

but i thought overheating vrm's wouldn't do artifacting, only throttle the speed... to high core and memory or overheating core/memory would do artifacting.

If your looking at a 290 I would go with the Power Colour PCS+ anyday.

i have a Asus 290X DirectCU II OC now...

it very weird because my last Asus 290X DirectCU II OC card was asic 71.5% and my replacement card is 75.1% but still it won't clock to say 1100mhz on stock voltage. it's either on these cards the vdroop is to much because it's like 100mv+ drop or these cards are poorly maded.

grrrr looks like i will have to rma this card, im getting artifacting at stock. if i up the voltage slightly the artifacting goes.....

im getting fed up with this now.
