Overclock Radeon 4850 via ATT vCore limit

[Venator]

This morning I tried to push the overclock my radeon 4850 with Ati Tray Tool to 750/1150 with a vCore of 1158 but the problem that is not stable> _ <And I can not push the vCore above, I have more choice after 1158. If anyone knows a way to exceed the 1158, it well help me
PS: I did not want my vmode graphics card, if that is the only way, So if it is the only medium, I give former 700/1100 overclock.

The VF1000 cools not only the memory it seems to me. Maybe your GPU is cool but your memory must suffer at this frequency.
And then Me the GPU at 750 MHz or 100 MHz is a bit too poor for a HD4850.I would say 70 Mhz max greater after it becomes dangerous. especially if the vCore is already increased.

Finally I say that mine takes hard 690/1125 then...

Worry not for memory, with my VF 1000 was provided ZM-RHS1, so everything is properly cooled is well XD (The gpu at rest increased from 67 ° C to 27 XD and full of 105 (yes, yes full of dust the old ventirad ) at 40 ° C and the memory is a 32 ° idle and 43 in full)

Otherwise I also bought a box ZM-RHS1 in addition to cool completely floor of the food. I touch the floor in full of power supply is warm.

Finally, I read, I know where the guys had managed to achieve 775 MHz in a stable voltage but what there is the issue, besides it is stuck at 1158 on ATT!

PS: I managed to create a profile 2D frequency ultra low lol Finally, the core 100 MHz with 0930 volt. But the ram, below 487 Mhz, it displays artifacts something strange lol

Hey, I suggest you to a test of your Overclock Radeon 4850 with ati tool, you do scan for aterfact and you see the result it gives.

Good, the 100 Mhz, it was a bad idea lol, enchainement screen black , so boot safe mode and reinstall the Catalyst, Besides, if I could use the 8.12, I would be happy , the 9.1 gave me something a little bug.

P.S- 500 MHz for the ram, ATT is an artifact XD to 505 Mhz, nickel any artifacts. Strangeness,Otherwise, the Core is a 150 Mhz, and it seems stable


I noticed in Crysis, with OSD ATT, I could watch the CPU usage for 15 minutes and I see that it never exceeds 80% XD So much evidence that the multi-threading is not to the point lol, strongly catalyst 9.2.

[.:MUNDITO:.]

It's not because your 2 cores are not used a 100% that your processor is not whether it can do no more he will do nothing more.

ATT OSD and if he displays his works has 2 cores 80% max is that the average general Proco work logically 80% max. why you think it will work 100%?

Remission is a yes ati drivers there are too many and it is optimized and ATT OSD which distorted the results .
