i bought HD6670 1GB DDR3 last week, and when i'm using it i can feel that there's something bottleneck the card
as i have 300W PSU
MSI K9AGM2 motherboard with PCIe x16 1.0
RAM 2GB DDR2
so, is the 300W PSU the problem that i can't get the maximum quality of the card and the best performance of it
and can i upgrade my RAM with my motherboard , and will it differ alot from DDR2 to DDR3 ??!
thank u in advance guys..
I think that the PCIe Slot is bottlenecking your card, as the card is compatible with PCIe 2.1 which is not backwards-compatible with a PCIe 1.0. The RAM and PSU are enough to hold the card, even though the card recommends 400W's of power supply, 300W or even 250W is enough to keep it good and strong.
That is true, some pcie 2.1 cards don't play nice with 1.0 motherboards. In some cases a BIOS update of your motherboard could help, so I recommend you try flashing the latest BIOS for your motherboard.
Thanks guys for your answer
sorry i forget processor its AMD Athlon 64 X2 5600+ 2.9GHz
i want to upgrade my RAM i feel it could make a difference someway but what i'm asking that can my motherboard handle 4GB of DDR3 or DDR2 only ?!
BTW i could play some of new games with 720P with no problem.
Unfortunately, your system is not very powerful, so your performance is normal, also note that you have 32bit windows, so going over 4gb of ram won't help as it won't be recognized in windows. However it won't make much of a difference, as your system in general is not very new. However if you bring back the settings a bit, and update all the drivers, etc. you should be able to squeeze out some more performance. With a 300watt psu overclocking isn't really recommended.
even though that cpu is outdated his system can still handle a radeon 7750 without being bottlenecked
its twice as powerful as 6670 ddr3 and consumes lesser power. so i suggest you upgrade to a 7750 gddr5
