I am determined to hit 3 Ghz!

post #1 of 20
Thread Starter 
Well, I found out last weekend what my highest possible overclock is on my 3700, 2.95 with 1.65 vcore. Specs to follow:
2-2-2-5 Timings, I can do CAS 1.5, but apparently there's a performance hit associated with 1.5?
Vcore 1.65, Vdimm 3.5, Vchipset 1.6, LDT 1.2.

I'm able to do 3.0 ghz, 300*10, but it's not stable. I started to bump up the vcore, and in OCCT, I noticed that as vcore increased, the test failed closer to finishing, so I concluded that as I juiced it up more, stability did increase, but I was running 1.75 vcore before I backed off at 295*10 at 1.65 vcore, where I'm comfortable. Is there another route I should take besides trying to juice it up, or is this the limit of the chip?

Loosen those timings for higher O/C I can reach DDR600 levels with my tccd on 2.8v and 3,4,4,8 1t remember to lower the LDT x3 recommended also I can go higher than DDR600 if I change my 1t to 2t and use a divider...

Still a nice O/C though for those tight of timings....

I'm certain that it's my CPU because my RAM will run up to 260 mhz at 1.5-2-2-5, and I'm on a divider which slows it down to 245.

I dunno what the problem is, but I hit 3 GHz pretty easily with my 3700. I set vcore to 1.6, ran a huge RAM divider (because I have cheap RAM), and had CPU at like 273 x 11.

I dunno, there are different steppings that might overclock better than others, yours was a good one probably.

2.95 is hardly a poor stepping. but that is so close to 3.0 it must be possible somehow. i cant get mine to 2.7 stable so i dont really have any pointers but good luck.

Give it a few weeks to burn-in. That might help it out. Or have you had it for a while?

I've had it for a little while, 3 months, but not at 1.65 vcore.
