X58 gigabyte extreme cant go over 200blk HELP

i7 920 D0@4.2ghz
quad gtx295
aptevia 1150w power supply
2000mhz ddr3 ram 3x2gig Gskill Trident
Cooling:liquid

i have a gigabyte x58 extreme motherboard cannot overclock cpu past 200blk no matter wht voltages i use or no matter how low i put ram speeds....am i getting limited by motherboard or the cpu???

Most definitely the CPU, most 920s can't go over without massive voltage.

What voltages are you using? My i7 920 takes 1.48v for 200BCLK, I haven't tried anything higher because Intel says anything over 1.4v is already unsafe.

I recently got a i7 930 that can do 200BCLK with 1.3v but I have yet to push it any further.

I'm no expert on your question but 200 bclk is not too bad from what i've read.
Here's Gigabyte own guide for oc'ing your mobo

200 base clock is pretty high... Also depends on what multiplier you're using. Hyper threading. Turbo. Turn off HT and turbo... those are going to require significantly more voltage to run. Still not working, either keep giving it juice or lower the multiplier. It'll take lots of Vcore AND Vtt. From my experience OCing 15 750, Vtt/IMC is needed for higher base clock/speed while Vcore is needed for higher multipliers/having turbo and HT will also need more vcore.

i am using 1.44 v\core
1.515 Qpi/vtt any lower wont run my 2000mhz ram
and a 21x multiplier
