Ok so, i keep things short and streight to the point:
I have an xfx hd 5670 of 1gb gddr5. I removed the decorative plastic:
And from having 50 and 90 on full load.. pass to have 33 to 55 in full load (of course also cleaned it all)
(if to lazy to read, pls, just check my 4 questions at the bottom)
So decided to start overclocking my 1 year old vid card.. i always had this program "msi afterburner" but this one don't let me touch the voltage, even wen i mark the boxes still don't show the voltage controls~ SO i downloaded "atitry tools" and with this one i was able to finally change the voltage from 0.99 to 1.1 and the temperature went streight from 38 to 50~52 in normal.. and got a full load of 66...67
Well, i started to overclock with atitrytools, but i don't know if this normal or not, but wen i set the overclock lets just say.. 800 (from 775) the core clocks stays there, i mean theres no minimum like it used to be before overclocked it, only stayed the max all the time.
Anyway, i tried to boost it to 840 and was ok.. i manage to boost to 860 and having a max load temps of 70~72 max. Tried the game "batman arkham city" and before oc had 30fps on full grafics, and after the oc i got to 40+ Also tested "Battlefield 3" with all ultra had 26~30fps before oc, and after oc got 30~38. If i go further then 860+ i get error, freezes, and graffics errors.
cpu: Intel core 2 duo E8400 3ghz
ram: ocz 2gb ddr2
os: windows 7 32bits
mother: asus p5kc
My native resolution is of 1024x768 and max of 1280x1024 i use max res all the time for everything (and yeh, my screen is far to old.. )
My main questions are:
°It is ok if the core clocks stay ALL the time on the overclocked settings? (again, before used to had a minimum of 157 i believe and went to 775 automatically wen needed to)
°Do i have to overclock as well the video memory? i have 1gb and never goes higher then 500 of use so i never really overclocked it.. but don't know if HAVE to oc for stability things? (if can explain this to me i would be really happy!)
°Theres any other/better program then atitry tools for overclock?
°For last question, long ago wen i overclocked the cpu.. a dude told me to set the "pci-ex frequency" from auto to 100 on the bios... can't really recall what was it for~ does this may affect the overclocking of the videocard in any way?
Thats all, thanks very much for read! and sorry my english sux lil bit to much..
