I bought my pc one year ago and here is my specs:

Processor: Intel core i5-3470 3.2 ghz
GPU: AMd 7870 gigabyte oc edition 2 gb
RAM: 8 GB ram
Hard disk: 500 gb hdd 7200 rpm
OS: Windows 7 64 bit
Resolution: 1600x900

Anyway my pc ran games perfectly when I bought it but now I have been experiencing more lag in games than before which really worries me so I decided to download the 3dmark demo from steam and when I ran the fire strike test ( the most demanding test of all) my score was incridebly low (4162), I have seen others with amd 7850 and they scored higher than that in the same test. Can someone please help me because I paid a lot of money on this pc and I don't want my gpu to die. Any help would be appreciated.

when did you buy it if from 2014 they cheated you bro but seriously it doesnt look like a bottleneck. Is overclocked maybe its damaged. is hardware acceleration enabled. In bios did you change anything. Are there any actions that led up to this messing with things,etc

what are you talking about? If you mean that my card is faulty then it would have performed like that from the beginning since I bought my pc which is not the case and no I didn't change any settings and I didn't overclock anything as well.

What power supply are you using right now?

The power supply is the most important part of your PC. This particular card needs at least 35A on the 12v, and under full load it has been observed to draw upwards of 300W

If you're running a low tier power supply, it could be one reason why your gpu is underperforming.

Another reason could be that you're running low on ram when running applications which can also affect performance.

Heat can also be a factor, if you're system is overheating, then your system will throttle to cope with the heat.

There's also a chance that you have something in your system like malaware or something. Scan your system.

Well I am using the same power supply which I bought my pc with. It is 650 watt but I still don't remember its manufacturer. But guys before any of you reply, does anybody know what score a card like mine should have gotten in the fire strike test, I know it is a stupid question but it is okay if there is no answer, I just want somebody to help me with my pc problem.

It should be scoring around 5200. Most likely, your power supply is starving the card of amps. I would recommend getting something with at least 40A on the 12v.

It will work well for a while, until the power supply begins to take damage because the card requires more electrical force than the PSU can supply. There is really no reason not to upgrade it anyway.

huh didnt know that. I hear people saying that so wait if i had a 350w with a 650w system would it work for like a year then die or what(not planning on doing this)

Well probably not, here's a scenario. Lets say you have a system that needs 500W and 30A to work. Your PSU is a run-of-the-mill 600W, with a 12v 27A. It will work for a while but the wires and circuitry are flowing more than they are designed to handle and sooner or later it will destroy itself. If it can't even get enough power to start up it just wouldn't work. You would probably get some awesome warning messages before BIOS.

I don't really think it is my power supply because I have done some research before I bought my pc and 650 watt seemed enough to handle my pc specs and if my power supply was really damaged my computer would have randomly shutted down which never really happened to me before even when I leave my pc turned on all day, the reason why I am so sure is because I had a very old pc with a damaged power supply and it kept on shutting down by itself. There might be some viruses on my computer since my antivirus is outdated so I am going to update it, scan my computer then re run the fire strike test and see if it will make a difference but for the record I don't really think 5200 is an accurate score range for my gpu in the fire strike test because the guy who got that score had a better processor than mine. I have done some research and some people had my gpu along with a core i7 processer and they got over 7200 so I guess the processor can heavily affect the 3d mark score as well.

There are a lot of things that could be causing this.

Rather than tearing your hair out .. sell the uker on ebay and buy a better second hand card

You want to see what brand power supply you have. If you bought an off the shelf pc there is a good chance your power supply is a pile of cow poo that, as said above , might work for a bit but is pants and is likely to have poor performance and lifespan. The W rating is not indicative of quality. So you cant be sure .....especially if you buy your pcs ready made !!

if you didnt run any graphics tests when your card was working well you dont have anything especially relevant to compare its current performance to. IME results vary a lot and stuff like your RAM and motherboard have a lot to do with results people get.

Yes like I said though Hoda, it may provide enough watts but not amps. I seriously recommend getting something from antec, seasonic, corsair or one of the other high quality MFG's of PSUs. Your entire investment can go to crap if your power supply fails. Not trying to be a salesman here, but i really really recommend you shop around and find a quality PSU that fits your budget.

Wait there is a misunderstanding, my pc is not ready made, I built it. When I said that I bought it in my first post I meant the hardware, sorry for the mistake.

Yes Steve1989 I get your point but what if it is not my psu, what if it is something else?

Oh okay. Well regardless, your PSU will have a label on the side of it with a table that shows various power ratings. What is in the table for the 12v+?

I'm trying to help you eliminate the PSU from causes of underperformance. The only other thing I can see is viruses or registry errors, also have you tried re installing your AMD driver?

July 8, 2014 6:27:51 PM

No I haven't tried re-installing the amd driver, I just scanned my computer using emisoft anti malware and there is no suspecious files in my computer so I guess that would take us back to the power supply, just give me some time to check my psu and I will post back as soon as possible and let you know about what you need to know.

Give us the exact make and model of your psu and it might just clear up this whole psu headache. This psu talk is getting a bit long and unnecessary.

Cheated? How? A 7870 is a 270X you know and they are still being sold.

And to the guy that said the 7870 requires 32amps has no idea what he's talking about.

Simple math for Pitcairn (not Tahiti LE) 75w * 75w * 75w = 225w / 12v = 18.75amps MAX.

300w? Impossible... perhaps full system load.

OP,

When it comes to 3Dmark you have to compare graphics scores and not total. If the score is low then I'd suggest re-installing drivers.

No, it most probably has been damaged as time has gone. A computer works kinda like an engine, parts gets worned out and you replace them

How could you make that assumption if the OP never even posted the age of the card? Besides, computer parts either work or they don't. 99% of the time hardware issues are driver related or a bad overclock.

i think your right about the other stuff. But the r9 270x is 7950. the r9 280 is 7970, r9 280x is 7970ghz just wanted to point that out

Wrong... Don't you research before you post and look foolish?

Quote:
The Radeon R9 270X based on the Pitcairn GPU is the refresh of the Radeon HD 7870. Like for the R9 280x, it’s a new name for an old GPU!


http://www.geeks3d.com/20131008/amd-radeon-r9-270x-laun...

R9 280 = 7950
R9 280X = 7970

Thank you guys for all of your replies and thank you RussK1 for your answer. You just made my day. There was never anything wrong with my power supply, it was the driver version. My driver version of my graphic card was 8.955 and all I did was that I upgraded my graphic card driver to the latest version which is 12.6 as I recall and voila I finally got 5288 as an overall score in firestrike test instead of the crappy 4165. Thanks for your driver re-installation suggestion, it did work out for me.
