4890 crossfire issues, 4890 and future graphics card crossfire issues

I haven't heard of such a firefight.,4 months of "Micro Computer" has a detailed review of HD 4890.,It's still available now.,It's recommended you buy it and take a look.。 According to the article, the dual-SIM crossfire efficiency of the HD 4890 is amazing, and the performance is generally improved by more than 80% in the anti-aliasing environment with anti-aliasing, and even 97% is close to the dual-SIM interconnection limit. Of course, the performance is far beyond HD4870X2,But what this brings is extremely high power consumption and heat,The temperature of the original fan main card reaches 94 degrees in a short period of time,And it is only a double HD 4890 firefight,It is recommended to use a power supply of more than 700W,If it is a 3-way firefight,Then a power supply of more than 1000W is a must。

In fact, this is unlikely.

Even if your power supply is allowed.

Besides, it's impossible to mix three different graphics cards.

Hybrid crossfire refers to integrated graphics working with discrete graphics cards.

The 4890 is better with the 4890.

Some game applications and running scores are more than 70% higher than those of a single card

Are you okay. HD4890 Crossfire.

Let's not talk about practicality. The electricity bill is enough to choke, and secondly, when that time comes, the single-chip graphics card can kill HD4890X2 in seconds, and the power consumption is low.

Secondly, there should be a limit to fever, what games are used to HD4890X2?

I now have a piece of sapphire HD4870X2 in my hand, but I regret it after I bought it, the first power consumption is amazing, and the second is completely uproar and can't be used, that is, the brother search makes it possible to use HD4890X2, and it is estimated that there have long been higher performance varieties instead. So, there is no need to think about the firefight.

By the way, a score of my i7 920 with GTX285. (At present, machines are used to write documents, and the performance is completely wasted in .......)）

No, ......It must be the same chip to be ......For example, you can take two HD4980 pieces for firefighting.

This kind of firefight lacks safety, and it will burn out if you don't get it right.

HD4860 and HD4890 can crossfire if they are not in harmony, and the device ID is different.

2 x HD4860 crossfire, need a power supply rated at 450W to be high potato shed bright.

You don't need any third-party software at all, you can see it in the ATI driver control panel (the catalyst driver interface has been revised, I will use the previous driver panel to explain it to you). If it is not enabled, select "enable" in it. (Don't tell me you don't know where the driver panel is).

As shown below:

Yes, no problem at all, as long as your motherboard supports it, the power supply of 600 watts is enough.

The HD5770 and HD4890 cannot form a crossfire.

If you want to build the HD5770 Dual SIM, the multi-core F1 is completely sufficient. But HD4890 is different, although its RV790 core is 55nm process, but because the working frequency is very high, the power consumption is impossible to be low, HD4890 single card plus i5 750 need to be rated 400W level power supply, if you plan to build HD4890 dual card system, then the rated 700W level power supply can be competent.

The HD5770 can only be exchanged with another HD5770.

No, the same cards are required to form a firefight. The power consumption of the 4890 is too high, the dual card is estimated to be very hanging, and the new 5770 has no problem.

Experiments have been successful under VISTA, but have not been confirmed under XP.

Can't、Only cards of the same model can be crossfired、Buy 4890 at this time.It's better to buy the power consumption is too high, two pieces....If you don't want to become an electric stove, buy 5770, buy a piece first, wait for 5770 to come down and then buy a piece, group firefight, performance is no worse than 5870, as for the power supply, on i5 and 5770 firefire without overclocking 400w is enough, but i5 is not super is waste, 955 can be seconds, so overclocking has to be 500w

No firefights. Two ATI high-end graphics cards can't go crossfire.

Only the high-end + low-end can be crossfired.

It seems that the highest firefight seems to be 3850, and the high-end is not capped.

4890 and 4890 could not exchange fire.

In other words, the 4890 can only be exchanged with graphics cards below 3850. It also depends on whether the motherboard supports it.

If the power supply is stable, it will be 500W

If LZ is the emperor of the picture, then use the DX11 graphics card.,It's better to get two 5850 to crossfire.,The performance must be better than 5870.,It's estimated that it can be close to 5970.。。。

Or else wait for NV's DX11 card? Finally, wait for the crack patch to come out and make a mix.。。。

Totally possible, as long as your motherboard has an interface available and the power supply is sufficient...

But you have to distinguish whether it is an independent physical acceleration card or use NVIDIA's DX10 card as a physical acceleration card, independent physical acceleration cards are generally PCI slots, and you are not picky about graphics cards, you can match any graphics card, but unfortunately because the manufacturer that developed and produced PhysX independent physical acceleration cards earlier - AEGIA has been acquired by NVIDIA, NVIDIA doesn't seem to have any plans to develop Windows 7 drivers for the outcast of independent physical accelerators, and if you need to use Windows 7, then using independent physical accelerators may not work. If you use a DX10 N card as a physical acceleration card, it should be noted that NVIDIA's new driver shields this collocation, and you need to crack the driver, or use an earlier driver to turn on physical acceleration. Sorry I don't remember which driver started the blocking.,Please check it on the Internet yourself.。

It depends on whether your motherboard supports it

It is not recommended to eat power very much.

Yes, but it's more troublesome.
