ASK A GURU : Technical trouble with your PC ? ASK HERE

1. if it stays at auto then will the speed be increased automatically while gaming??

It should be increased as the workload on the GPU and hence the temperature increases ! You can check by leaving the Rivatuner monitoring graphs ON and playing the game, after quitting, you can take your mouse pointer on the graph to show the speed or duty (in percent) at which the fan was running during gaming.

2. If i increase fan speed to 100% then will it shorten the life of fan or damage it??

No damage will be done for sure, although life expectancy may be reduced, better to just stay a little off the 100 mark, say 80 >?

3. What are the safe temps of this card? specially during summer.

As answered earlier by A.Rafay, 80 degrees !

the problem im getting is i get exatcly 90 fps on cod4 when all settings r high 1440x900 and it remains the same if the settings are low

This means that there is a bottleneck. The GPU is still capable of more but the Processing is not fast enough, thus the GPU is being limited ..

Although no need to worry much, this is normal for multi-GPU setups. You can overclock your processor and the FPS should increase, or you can inrease resolutions and AA, AF, to get much better graphics...

further more the catalyst softwars says my one gpu is disabaled ...
i need help as how to turn the other one on

Did you try another driver version ? And did you check with other utilities, like RivaTuner or GPU-Z ...

so don't worry, run some benchmarks such as 3dmark vantage to check if both of ur cards are being utilized or not.

^ As ragingflares said, you should definitely try 3dmark and then compare with the scores of other 4870X2 users, this will tell whether the two GPUs are enabled and active or not...

plus if i open a few things at once my pc restarts

Right Click My Computer > Properties > Advanced > Startup and Recovery > Uncheck Automatically Restart

Then if you get a Blue Screen next time, check which file is causing problem..

If the computer restarts without showing any Blue Screen after unchecking this option, then it is indeed a power issue.

And according to this review done by Xbitlabs the 4870 X2 doesnt utilize more than 280 Watts ..

And according to this review, the whole system took 426 Watts when the GPU was fully loaded !

So my bet is, its not the PSU, or the PSU is faulty ....

The 650W Corsair PSU should easily be able to handle your system specs ...

edit, apologies to the mods, in the condition that if only the official hardware guru's here are allowed to respond on this particular thread, if that's the case please delete my post

I dont know if that's the case or not, but I personally think everyone should be allowed to participate, plus we will find more potential gurus this way

^ yaar i know the difference between two 4870s and one 4870x2, the single 4870x2 is basically two 4870s with 1GB memory each giving a total of 2Gb video memory on a single external cover, but it still works and gives performance almost same as two individual 4870s connected in cross fire.
about one card being disabled, i surely think its bcz of not enough power being supplied to it, maybe some sort of safety precaution in the software, cause not enough power damages any device, do give ur findings after u get the 1000W psu, i hope INSHALLAH ur problem will be solved, best of luck

run some synthetic benchmarks just to be sure..

i Got a Problem with my 80Gb HDD....I m hearing some wierd Kind of Sound from it and my Computer is Running Really Slow.....Can u fix it on my own?? do i have to get it repaired or do i need to get a new one? Please someone help me

[Ateq]

^ That sound means your hard drive is damaged and is also the cause of low performance. You can try to have it repaired from some 'respected people' or if they ask too much, and if you feel like you shouldnt risk it, then get a new one.

Wats the Approx Price of a new 80Gb one?

[fajoo24]

well this is not actually a question, just wanted to share with u guys....

i thought that to run rams in dual channel, they need to be of equal size and speed.....well guess what i had 2x1gb kingston ddr2 667 running in dual channel and yesterday i boughth another kingston ddr2 2 gb stick 800 mhz.....

even my 1 gb + 2 gb are running in dual channel .....i have now put all 4 together and they are running in dual channel too on the oclocked system......

Check galaxy.pk for prices...

I would say better just go to a shop that deals in used stuff, sell him your current HD and buy a used 80GB HD off him.....

I am not getting this completely, you say 2 sticks of 1 GB (667) and another of 2GB (800), so that makes 3 RAM modules in total right ?

In theory, only identical modules can work in Dual Channel mode for every dual channel configuration, that means, in a motherboard that supports Dual Channel and has 4 slots, you can have 2 identical RAMs in one dual channel config. e.g 2*512MB and another identical pair in the other two slots, e.g 2*1GB, that would make a total of 3GB memory running in dual channel mode......

So either I am not correct with above statement, or I am not clear on this.....

yes u understood it right, 2 sticks of 1 gb each both 667 mhz and another 2 gb ddr2 800 mhz stick....

yes i also knew the same but even if i run 2gb + 1gb together in same coloured slots, they are still working in dual channel

[Ateq]

^ That's new ...

[Sire Ahsan]

yes i also knew the same but even if i run 2gb + 1gb together in same coloured slots, they are still working in dual channel

All three are not working in dual-channel. Only the two sticks in the same coloured slots are.

Simple reason ... its DUAL channel ... TWO channel.

Take it from personal experience, get another hard disk as soon as possible.
