Overclocking the 1055t

It's seems I've hit a wall and I'm unable to overcome it; At 3.8Ghz prime95 fails the test (worker stops) after ~3 minutes.

I can overclock at a fully stable 3.7Ghz @ 1.44v as listed by cpu-z (Voltage set in bios is 1.4v) with FSB 265, CPU-NB 2119Mhz @ Stock Voltage, RAM 1412Mhz @ 1.5v.

I've spent hours trying voltages for the core, CPU-NB and RAM but 3.8Ghz just wont pass prime.. Is it possible that some 1055t's that just can't hit 3.8Ghz? It seems like no matter how much vCore I give it (didnt go past 1.525v), it just wont do it - even with everything else under settings which run impeccably at 3.7Ghz.

Much appreciated.

  1. every cpu is different, there are probably some that can hit 4ghz. also maybe its your motherboard, a phenom x6 draws a LOT of power running all cores at max in prime. a 4 phase power motherboard wont cut it, you would need a good 8 phase board with cooling on the VRM's and other major IC's on the board.
  2. I'm running my 1055t on a gigabyte 990fxa ud3 with 8 GB (2x4) of corsair XMS3 1333Mhz RAM, if that helps at all. I know the mobo has 8+2 power phases. I can live without 4Ghz, but I would like to hit 3.8Ghz. Is there anyone else that's having the same problem? -(ending up with a lemon of a 1055t)
  3. 3.8ghz. - fsb at 271 vcore at 1.45v , cpu nb raise 0.025v,
    Ram corsair xms 1333 does not strong for oc fsb, that's need drop ratio ram to 1066 (very storng is 1600 ) , you must do small increase ram voltage +0.015v - 0.065 (max at 1.65v). If you had LLC set extreme/high or maximum.
  4. I'm using a M4A79XTD EVO with a 1055T and I'm stable at 3.75ghz. I have a 4 pin power connector for mobo though :'( I've been messing with settings and voltages but can't get the system stable enough to play Black OPs over 3.8ghz. I've managed to run at 3.9ghz but when running prime95 core 5 fails an the other 5 cores seem to be doing ok. I managed to boot windows at 4ghz but only had enough time to take a screen shot before windows crashed lol. For now I think I'm going to stick with 3.752ghz under full load i'm at 40 degrees Celsius. When I built this system I was hoping for 3.6-3.8ghz so I guess I got what I wanted.

    While my multiplier is x14 I can't pass 270 FSB. When I dropped the multiplier I got FSB up to 290 and booting into windows. I may try dropping multiplier to x13 or x13.5 and see if I can crank it up a bit.

    How important is NB fq and HT fq.. I have NB at 2400+ and HT at 2144 right now.
