Solve : Graphics Card Performance Tip?

1.	Solve : Graphics Card Performance Tip?
Answer» Remain apprised of your motherboards limitations and fiobles . I have a GTX 1070 and on a lark I ran GPU-Z a few days ago. I noticed that it was showing the card as using PCI-E X8, rather than PCI-E 16x. I suddenly remembered that my Motherboard Manual specifically mentioned that populating both x16 slots would reduce both to 8x; I had a sound card in the second PCI-E 16x slot. I "knew" about this limitation but I suppose it never occurred to me until I actually checked GPU-Z and pieced it together. I didn't think this affected performance very much. I wanted to remove my Wireless card anyway (no longer needed, as I'm using Wired Ethernet) and decided I may as well rearrange the sound card to use the x1 slot that the wireless car was using while I was in there. Afterwards I decided to see if it was worth it and use 3DMark to test it again. Maybe a 10% difference at best. Boy was I wrong- The scores were a little over double what they were before! Everything was already running smooth as silk sheets, but now it was like doubling the thread count.The GPU-Z and CPU-Z utilities are a must after building a system or upgrades. I found out with GPU-Z that my card wasnt what i thought it was. I thought my GPU's clock was 902Mhz and it was only 700Mhz Quote Significantly higher effective memory clock speed 5,012 MHz vs 1,600 MHz = Around 3.2x higher effective memory clock speed Higher clock speed 902 MHz vs 700 MHz = Around 30% higher clock speed Significantly higher memory clock speed 1,253 MHz vs 800 MHz = More than 55% higher memory clock speed More shading UNITS 384 vs 96 = 288 more shading units What i found out is that i got these 730 GT cards backwards when buying the card, and the 2GB card is only 700Mhz and 1GB card is the 902Mhz. To me when I clicked buy I was THINKING faster clock and more memory, but nope. CPU-Z pointed out a lack of Dual-Channel memory support for my 25 watt Sempron 3850 Quadcore 1.3Ghz AM1 KABINI. I bought 2 X 2GB sticks thinking have 2 sticks for dual channel 4GB, but Kabini processors only support single-channel. So I might as well have bought a single 4GB stick. http://cpuboss.com/cpu/AMD-Sempron-3850 Additionally I was working with an older system a few weeks ago thatw as given to me from prior owner who said it was too slow and it seemed unusually slow. Come to find out CPU-Z pointed out mismatched RAM. A slower memory stick in the system was bringing the FSB speed lower with 667 and 800Mhz DDR2. Checking on the RAM sure enough Slot 0 had a 667Mhz stick and the other slot has the 800Mhz stick. I found a good 800Mhz DDR2 stick and replaced the 667Mhz stick and slight performance gain. Memtest86 also run after this to make sure the mixed brand RAM played well together.

I have a GTX 1070 and on a lark I ran GPU-Z a few days ago. I noticed that it was showing the card as using PCI-E X8, rather than PCI-E 16x. I suddenly remembered that my Motherboard Manual specifically mentioned that populating both x16 slots would reduce both to 8x; I had a sound card in the second PCI-E 16x slot. I "knew" about this limitation but I suppose it never occurred to me until I actually checked GPU-Z and pieced it together.

I didn't think this affected performance very much. I wanted to remove my Wireless card anyway (no longer needed, as I'm using Wired Ethernet) and decided I may as well rearrange the sound card to use the x1 slot that the wireless car was using while I was in there.

I found out with GPU-Z that my card wasnt what i thought it was. I thought my GPU's clock was 902Mhz and it was only 700Mhz

Significantly higher effective memory clock speed    5,012 MHz    vs    1,600 MHz = Around 3.2x higher effective memory clock speed

Higher clock speed    902 MHz    vs    700 MHz    = Around 30% higher clock speed

Significantly higher memory clock speed    1,253 MHz    vs    800 MHz    = More than 55% higher memory clock speed

More shading UNITS    384    vs    96    = 288 more shading units

What i found out is that i got these 730 GT cards backwards when buying the card, and the 2GB card is only 700Mhz and 1GB card is the 902Mhz. To me when I clicked buy I was THINKING faster clock and more memory, but nope.
