OC3D Review: Sapphire 4890 Vapor-X PCIe Graphics Card

"Can Sapphire's vapor X cooler keep this maniacal overclocker of a card in check or is it just a lot of media hype and hot wind? Find out in our latest GPU review..."

Sweet review man, massive props to Sapphire for final sticking a non reference cooled card on the market. Any idea when these will be available?

Nice review as always my good man!

I wasn't sure that these coolers would make much odds over other after market coolers but those temps are pretty damn good.

Well actually I am not quite convinced. You see almost solely based on this review I went merrily our and promptly bought 2 of these cards only to find that .

1) They run a lot hotter than stated. 67 Celcius at idle and run so hot when gaming that my PC crashes. I haven't managed to record the temp just before crash-poin but I have seen it at upto a blistering 93 Celcius!

2) I don't get anywhere near the FPS stated in the article. Infact I get exactly the same when playing CoD World at War online with 2 of these cards in crossfire as I did with one 9800GTX+. Namely 91 FPS.

I have plenty of ventilation in my rig and the fans on the HD4890s are certainly working.

At +4000rpm (confirmed by ATIs own CCC program and CPUIDs Hardware Monitor) they are audible let me tell you.

I don't believe my system is to blame despite it not being cutting edge.

Sapphire recommend a bigger PSU. 650W-750W and monitoring my temps with rivatuner.

I have a 620W PSU and run Vista ultimate 64 bit, which doesn't allow rivatuner to work since I downloaded the latest update if you can call it that.

Sys Specs:- [email protected] with Thermalright Ultra-120 eXtreme cooler and Noctua NF-P12 fan. ASUS Maximus Formula Republic of Gamers motherboard with X38 chipset and 4 GHZ of Kingston HyperX PC9600 RAM @ 1207MHz being cooled with a Corsair Dominator Airflow Fan.

CoolerMaster Real Power M620 Modular PSU.

Vista Ultimate 64 bit OS.

Samsung SpinPoint T166 HD501LJ 500 GB.

All incased in a Aerocool Hi-Tech 7 cabinette with a 40cm fan on the side and 2 x 12cm fans, one infront and one at the back.

Any good advice would be appriciated.

Bilko out.

Hey Bilko, believe it or not your system is a quite a lot inferior than our test system.

You CPU is not only slower than our i7 CPU but it is also clocked a lot slower. CPU bottlenecking, which you will almost certainly have with 2 4890's at your current CPU & clockspeed, is the most likely culprit in why you are not seeing good FPS. You are also running with 4GB of DDR2 at a much slower speed than the test systems 6GB of DDR3 which is running 400MHz faster than yours. I don't wish to put your system down as it sounds like a sweet setup but our test setup is specifically designed not to bottleneck any product we throw at it and as such any product we review is done so under optimum conditions.

Rivatuner works fine with Vista 64bit. I use it to overclock NVidia cards.

Your PC is most likely resetting due to power requirements I'm afraid. You would most likely begin to have corruption on the screen or a BSOD if GPU temperatures were an issue. Because your PC is shutting itself down with no warning this points to an overloaded PSU. Comparing your temps to the ones I recieved while writing the review is not conducive to solving your problem. The temps I recorded were taken in an open system in an air conditioned room held at 23c ambient apx. With the recent temps it really is no surprise you are getting high GPU temps. Take a look on any enthusiast forum and everyone is moaning about high CPU and GPU temps at present.

If you do manage to sort your power issue out, I really wouldn't worry about 90c under load conditions on a GPU, running cards close together in crossfire (especially on a maximus X38) will inevitably increase temps but they can take 90c+ all day long.

@bilko, i bet that the fps in cod waw are capped at 90fps which shows 91fps. You need to raise the maxfps to 125 or 250 for example.

in the command line, type: /com maxfps 250

WOW, what is wrong with the hd4770 and gts250 idle power consumption in your graph! They are bothe 40watts more that the gtx285!! And consume more power than the hd4890

Looking at his goods (oh my), I don't think this is his problem.

Whilst using a superior cpu is always the better choice to put the emphasis on the gpu in real games, the cpu does however slant results from artificial benches, with the better exception being vantage (it doesn't seem to benefit as-much). But what can u do, u have to stick with a platform best for longevity of testing, and stay current.

I'd personally expect no bottleneck from the stuff he has due to the cpu. Imo he has something else going on.
