Is the Sapphire 4890 Vaporx for sale yet. Where

Keep in mind other aspects of your computer can contribute to overclocking. Case cooling, adequate/clean power supply, Quality Motherboard, Clean driver installs.

-VD

I had my fan cranked up to get that high of a core..

Pics and benchies pls!!

[Cool Mike]

Getting my Toxic tomorrow (Friday). Ready to pump it up!!!!

it's goin' back tomorrow DOA! hopefully i get a replacement quickly

i will post pix when my new build is complete (need the replacement card and a new HTPC case) and benchies you will need to get from someone else

That's balls man....I'd be pissed if I was in your shoes!!!

[intel igent]

what can ya do?

i can only cuz it's better than at least my supplier is willing to go to bat for me and help with my RMA

LOVE the peep's/service i get @ pcvillage

i'll get a pik up later tonight of the broken piece.....

Whats with all these random overclocking results - they are all the same cards ><

http://www.techpowerup.com/reviews/S...apor-X/31.html

The overclocks of our card are 970 MHz core (1% overclock) and 1100 MHz Memory (5% overclock). Both overclocks are very disappointing but were to be expected since the default clocks are already quite high.

No doubt different batches have different quality binned chips, the bottom line is that the VapourX are likely to be lower binned GPU's generally across the board (although I am sure there will be exceptions)purely because they only stock at 870mhz as opposed to 960 or 1000mhz, there are plenty of cases of Toxics hitting 1030+mhz out of the box.

I ordered the Toxic in the end, purely because I found an even better deal that the Atomic (£180), if it dont give me over 1000mhz then it's a rivatuner voltage tweak for me!

[ShogoXT]

Im guessing my atomic OCs arnt that great because of me sandwiching them together?

[Tatty_One]

Got the Toxic today, 1050mhz out of the box, OCCT GPU stable (have not tried a 2006 or vantage run yet though), going to try the Rivatuner voltage mod tomorrow if I get time.

What you getting with them?

[ShogoXT]

I have to turn the fans to 80% to get 1025.

Are you sure it's not 1.4V? I thought all Toxic versions use 1.4V. If you are getting 1050mhz out of 1.3V you have a very special card, in which case I'm insanely jealous.

*Oh, you have a link or advice on using the RivaTuner voltage mod?

[intel igent]

gotta love crackberry pix

[Cool Mike]

Recieved my Toxic Yesterday. Running 1050/1200 65% fan. Idle temp 40C. Passes vantage graphics test 2. Will not pass both 1 and 2. Ran Hawx (max settings, DX10.1) for one hour with no issues. Warm in my computer room/office could be a factor. (78 degrees F)
I am sure if we had a solid solution to bump up the core to say 1.415-1.435 we could hit at least 1075 core.
A reference 4890 core voltage is 1.312 I believe. I am sure the Toxic is 1.4
Excellent card!!

No it's definatly 1.3, well 1.3 and a bit, check the RBE screenie, and here is a guide for rivatuner..... always a pleasure for a friend!

Edit: Although it's showing 1.3V in BIOS, in Rivatuner and GPU-Z it is showing 1.4V..... strange.

Thats very nice, I tried a CCC auto tune for the card, it gave me 1070 on the GPU!!! Not sure how stable that is (probably not) but it's worth a 2006 run to at least try. Check the link to the guide I have posted above, it is apparently proven with the HD4890..... Good thing about this mod is that I assume that if you dont open rivatuner you continue to get stock volts, only when you open rivatuner should you get the added voltage.... I am assuming thats how it must work once it's done.

it's hard to make out in the pik but that lil' resistor thingy beside the power connector is broken from factory

[Tatty_One]

That Rivatuner voltage tweak is easy! You can even turn off OVP/OVC which is a good thing because whenever I went for high 3D Clocks I got BSOD at 1.425V which I worked out is what I need for 1100mhz which I am happy with, eventually I realised that you can set OVP/OVC upper limits to "0" which is un-active, then she worked fine, dont want to go any higher, simply because although this VapourX cooler is very nice, i dont wanna push those VRM temps too high and risk the card frying, I think high 80's low 90's for VRM's at 1.425V on OCCT GPU stress for 5 minutes are OK temps, here is a screenie of 1100mhz goodness after a few minutes of OCCT GPU stress test without artifacts, forgive the quality, I had to downsize considerably....... not tried Vantage/2006 though which will be the big test.

I am on cat 9.5's, CCC goes a bit strange when the cards overvolted and was flickering whilst i was doing the stress tests, the readings went all over the place also, GPU-Z also reports different temps on the VRM's to Rivatuner also. Would be interested to know if anyone else tries this on a different Cat if they get the same issues.

Edit: I see the link for instructions above.
Tatty, I would like to give this a shot. I am an electronic test engineer by trade but havent tried this using riva tuner. Could you give me step by step instructions on how to implement this safely? By the way, I have the 4890 Toxic. Thank you...

Edit: has anyone tried flashing atomic bios to a Toxic?

No point, in flashing, I have checked the BIOS to compare entry for entry with the Toxic, it's identical except for the stock clock speeds which you can set in overdrive anyways for the toxic, even the CCC upper O/C limit remains the same at 1100mhz

As for the guide, the link is in my post 343, just follow that, it's what I did.

Edit:

The one thing the guide does not mention is OVP and OCP, with mine, if I set the voltage above 1.425V then it would crash as the OVP sets in and reduces the card to 2D clocks which of course wont power the overclock, if you look in setup (you will know what I mean when you get to changing the voltage) you will see an entry for OCP and OVP, you need to change the upper limit from 1 to 0 on each which will disable it, then your good to go.

On top of that, once it is set, whether rivatuner is open or not you will ALWAYS get the higher voltage when in 3D mode but it is easy to reverse it and then just go into rivatuner and raise it again whenever you want to, once you become familiar with it.

That's ballz. Are you going ti RMA it?

[Tatty_One]

One other thing I should have mentioned on the rivatuner voltage tweak, you probably dont need me to tell you this but please dont go too mad with the voltages, even with the VapourX coolers you may want to keep it under 1.45V even for just benching as those VRM's still get warm, I reset mine to stock unless I am benching as the card at 1050mhz handles anything in any case and just tweak it when I bench which once you get the hang of it takes about 30 seconds only.
