Low frame rates on i7?

i finnaly got G.R.I.D to work on my core i7 setup but i get really low frames rates while playing at 1600x1050 res. so i decided to play at 1280x1024 and still the same. my cpu is running 48c and load and my hd4870 is also running mid 60's at load. anyone know why? i ran the same game on my core 2 quad and it ran alot faster with the same video card(got about 85fpss with everything max) could my PSU be the problem? it a raidmax 650 watt.

my specs
core i7 920 (stock)
6gb G.skill (1800Mhz)
HD 4870 512MB
500GB drive
650 watt psu.

  1. You know what's funny. I had the same exact problem with Need For Speed Pro Street at the time. It was running nice and smooth on Xp. As soon as i install Windows Vista. Forget it :o . choppey and ugly stupid even at 800x600. so i went back to Xp and that did it. you're specs aren't the problem I myself am running Core i7 920 and it's sweet don't feel like you wasted your time.

    Power supply is fine, i've never heard of the brand though. As long as you have the right amperage on the +12v rail you're good.

    But seriously. Get Need For Speed Shift.
  2. Turn off the HT and try again! HT is the biggest hindrance in gaming. In addition, install the most recent stable driver for your video card! Good luck!
  3. Wrong, I actually had the latest drivers installed at the time. Like i said it only did it in that particular game, all other games worked fine which I found strange

    ht is off and i still get LOW FR in any game that i play. i tried vista, xp and 7 all the same. i just don't get why its so slow when my brother is able to play the same games with a much slower system and get way better performance.

    its not a OS problem i tried XP, vista and 7 all the same. the only think that i an think of is the PSU not supplying enough power to my video card and cpu.
  6. what operating system are you currently running. I assume you have latest drivers of video. try getting an older version of the drivers(might work). Properly clean your drivers. with Driver Sweeper. (install the program, uninstall display drivers, reboot in safe mode. Run driver sweeper clean the rest of the Ati files that are left, reboot. try re-installing the display drivers. What is your Amperage on your +12V rail of your PSU
  7. Consider checking your CPU/memory voltages and settings. I had some performance issues that were resolved after I found a good balance between memory speed (didn't try to run at max 1600 Mhz, running smooth at 1333Mhz) and voltage (increased QPI/VTT to1.3v and DRAM to 1.60v). I had to make these adjustments because I have all memory slots populated. Just something to check out in case you are overclocking or your MB does not do a good job of setting things when set to auto. Good luck and let us know if you're able to resolve your problem.

    i am using windows XP (64 bit) and yes i have the latest drivers from a clean install of windows. the +12v rail is reading a 11.98 never goes lower than that.

    running everything stock for now. 1.3v on cpu 1.5v on memory all other voltages are at auto.
  10. No what i meant was check the amperage on your power supply( from the sticker) verify the +12v rail. maybe your PSU has more than one rail. how much amp does it have on that particular rail(s)? And afterwards check the required Amperage for your video card should say something like required 450 Watt power supply with a minimum of 24 Amps(example)...
  11. yup 2 +12V rails one at 20A and the other at 18. its weird to have 2 12v rails at differrent amps/ oh well.
