    AMD Llano A6-3650: Problems above 120MHz FSB when using iGPU

    in Llano OC

    Posted

    I knew it was the VGA port because I literally tested everything else! I'll buy a VGA to DVI-D adapter and I hope that everything turns out fine. Thanks for the quick input guys :)

     

    @Iron: Dont worry, I already knew that 120-125 is not the limit when iGPU is used. If I thought so, I wouldnt post this thread after all ;) Thanks to HWBOT database as well, because I saw all these people doing crazy FSB with iGPU and I told my self: You fail again, you are doing something terribly wrong :D

     

    As soon as I finish my review, I'll test the A6-3650 on SS @ -40*C, and then LN2 who knows :D;)

    AMD Llano A6-3650: Problems above 120MHz FSB when using iGPU

    Hello everybody! I jumped on the Llano wagon as well and I'm quite surprised to say the least :D I'm currently testing an A6-3650 on a Gigabyte A75M-UD2H for a review. Everything's perfect, I've learned the system and its "tricky" spots, I've already hit 2500MHz RAM with air-cooled CPU/RAM and I was about to move to SingleStage testing @ -40*C. What's my problem?

     

    Using an 8800GT I can hit around 145MHz FSB on air-cooling, maybe a little bit more. Using the 6530D though (iGPU on A6-3650), the last stable FSB frequency is 120MHz FSB sharp, which means that GPU tops at 444MHz (stock) *+ 20% = 532MHz core clock. I've seen others on hwbot benching on air with > 140MHz FSB while still using the intergrated GPU. How is this possible? I've tried everything, from voltages and CPU/RAM multipliers to VGA RAM size, EHCI Async Data Cahce and stuff - whatever I could find @ BIOS I already tried. Can you help me out a bit? Maybe it's something I missed, I dont know... Maybe it's the fact that I use the VGA output of the UD2H and not the DVI one? I've tried PCI-Express up to 120MHz but still I can't manage to get more than 120MHz FSB using the iGPU :(

     

    How are these guys for example manage to hit such FSB on air-cooling with the iGPU:

    3) http://hwbot.org/submission/2198114_rebelion_3dmark11___performance_radeon_hd_6530d_1066_marks

     

    Just to clarify, I'm not questioning the above-mentioned scores. There must be some trick though for such high FSB. I find it hard that my chip's iGPU craps out at 120MHz FSB.
