    Default GA-EX58-UD3R 1.6 BCLK wall

    Hi guys, my x58-UD3R rev 1.6 has a BCLK wall at 215MHz, I can do everything 3D, memtest, linx, prime, occt ecc...fully stable but with 216MHz doesn't boot up or freeze immediately
    Do you have any advice?

    I guess that the bclk wall is from ur processor. Not ur motherboard.
    U could increase the bclk multiplier to achieve higher clock speed.

    unfortunately I am sure, I have tested another cpu ( 965 ) with the same bclk wall and my 920 on Asus reach 232MHz

    There is a commonly refered to 222 BCLK wall on some Gigabyte boards, maybe your specific one has the same but at a lower BCLK?

    A hard mod of the PCIE bus is required to get past this wall. I know some boards are shipping with this change implemented at the factory, but not sure which ones. The X58A's will definitely be done, and I think the current ons are the latest revision of some UD series.

    UD3R rev 1.6 has this change implemented at the factory, I am so surprise of this low bclk

    Not all motherboards can achieve such a high BLCK. Some might do better, others not so well. Yours probably caps at about 215.

    Luck of the draw unfortunately.

    Do you also have to rise the PCIE frequency after the hard mod is done? Don't know if this applies to the factory revised ones too. I think this is why I've seen people running 230+ BCLK and having PCIE at ~125MHz.

    Whether that's a good idea or not I don't know. SATA, Sound etc is all locked at 100MHz any way, only thing effected should be the full length slots.

    Yes, rev 1.6 is already modified. To get above 215 you should not need to raise PCIE but you may. Much above 222 you will though for sure, 103-108 seems to work best in my testing. I have reached 240 Bclk with only 103 PCIE freq, nut do normally use 105-108 when benching or pushing for max Bclk.

    Are you using enough Vcore and Vtt, how about IOH? I just ask because I have used many modified and unmodified boards with several CPU's and none of them had any issues getting 220-225 without pushing PCIE. Meaning all unmodified boards even could do 220-223 without additional PCIE freq, you just have to raise the voltages to the proper amounts

    Mine hits the wall right around 200mhz.

    But I did a little testing, and it's not the bclk for me, it's the QPI link, when it goes above 7200 (3600mhz) bad things happen.

    Try testing that. So instead of using 36x, use 44x and 175mhz, that'll be roughly the same, then try 176(7,8,9) if those lock it's not actually the BCLK but the QPI link.

    I don't know a solution, just how to verify the problem.

    Thanks for confirming this Lsd. I had a feeling PCIe frequency was involved somewhere along the line.
