So, for some reason the only program I can use to fully overclock my GPU without hitting a preset limit is AMD gpu clock tool. Every other software has capped my overclocks like so: Core max: 712MHz, Memory max: 550MHz. With AMD Gpu clock tool, I can push my card as hard as I want without the software limiting me. Why is this so? Also, NO software allows me to ajust voltage. Thats no fun!
My card: MSI Radeon HD 4650 MD1G 1GB GDDR2, default core: 600MHz, default memory: 500MHz.
(I know its dated, I got a new one and Its on the way. Should be here on the 7th. Gigabyte 6770 1GB (GV-R677D5-1GD))
