Hi guys, i have increased my budget and now currently lookin towards hd7850, the problem is i have only a pci-e express x16 1.0, will the hd7850 be able to support? I dont really care about less efficiency jus wanna know will it support, here are my specs
Intel core 2 duo E8600 3.0ghz
Socket L55 motherboard
I m currently usin a nvidia 8400gs...
Power supply 550 watts
I did a little Googling to try to find the answer. Apparently PCI-E 3.0 is backwards compatible with 1.0. You do apparently get some performance drop-off though. I don't personally know how much. Here's the source of the information.
Fugggitaboudit -- You are moving to a near-useless-for-gaming nVidia 8400gs to an HD7850. For the record, PCIe Gen1 x16 transfer rate is 2GB/s. Without knowing your resolution it's hard to say, but it just does not matter. You should be more concerned with the age of your power supply, though the HD7850 is highly efficient and a great over-clocker.
Bro, i usin 550 watts... So will support? I m choosin between hd7770 and hd7850... Hope can support... Its okay abt the performance.. Becos i shld be chgin a motherboard early nxt yr.. Jus wanna see can it support my current useless com
the power requirements for a 7850 state 500W, and so is techinically your current ps is fine for the new card. However, as wisecracker eluded to, chances are your psu (judging by the the slightly older tech)is quite old, and maybe not as efficient as before. the psu may not be good enough to supply the power needed. if you can give the name and model number of psu, we can bette advise if it's sufficient.
Ohhh, but the hd7850 is supported in pci e 1.0 right? I am currently decidin on either hd7770 or hd7850...? I do not know which would be better for long term usage...wad type of power supply would u recommend too?
When the test ends, a folder will open which contains a series of charts. These charts show system behavior under **full load**
This will establish a baseline of your *clean power* - what you are looking for in the charts is the voltage line and *Ripple* (or drops in voltage). I think it's the light blue line. OCCT will test across all volt lines of your computer including your CPU and GPU in the various charts.
At the top of each chart, it will also state the level of ripple. And yes, 98.9% of the time you will have no issues with PCIe Gen1.
OCCT will also report your motherboard model --- you may check that model number across the internets for any past issues (if any) on the PCIe slot.
edit: I fergit ...
After you install your new video card, you may run another OCCT test to compare to the first test. Hopefully, you will pass with flying colors.
Or, not Don't run the specific GPU test (it's called *Furmark*). It tests well beyond any typical gaming load.
i know your feeling... i had 8400gs and i decided to sell it to my brother and bought HD 7790... my specs are:
Dual Core E5700 3.0Ghz
500w psu applegreen(cheap psu)
i had 8400gs but now i had 7790
the 7790 is pci-e 3.0. my motherboard only have pci-e x16 1.0.
it works and i cant see the difference using 3.0 or 1.0 version on this card... but my cpu and ram is bottlenecking in most game.... it has sudden lag sometime because of the cpu
game tried so far:
Dirt 3 ultra = 36fps avg
gta iv low = 28fps min avg 34fps
now downloading more game
im planning to buy quad core 775lga
hope this help... i suggest if you buy 7850 you need to overclock your cpu..
