My best attempt so far--1055t, 4.0ghz

That's the best I've done in the year or so I've had this processor, and it was an unstable suicide run =[

I basically nerfed the crap out of everything but the CPU frequency and raised the voltages to uncomfortable levels and I couldn't get it to post at 286 no matter what I tried. 282 would post, but wouldn't actually get to the login screen.

Any thoughts?

that is a lot of vcore on that beast. hmmm try loosening up the ram timings and keep the NB as close to stack as possible to rule it out. Question what are your temps with that voltage.

not sure what im doing wrong or right but i literally just raised the multi and went straight to 3.9 with no issue.

the smallest increment on voltage and another few multi`s i went to 4.0 no probs?

my problem is im not sure how to properly overclock? I have my idle temps always at room level (although i seem to go no lower than 15deg on idle even with room a bit cooler) my max temps 47deg

my board is an 890gx gigabyte and i use a Alpenföhn rev B cooler which is fairly amazing for air

Raise the multi to17x, set the FSB to 245, loosen the RAM timings. See if that gets you a little further.

Good attempt otherwise thumb.gif

The HT link needs to be close to stock, not the CPU/NB. On the contrary, the NB frequency should be @ 2500-2800Mhz to ensure higher stability and boost performance. Be careful with that board though, it's a bare 4+1 phase setup. Ensure proper cooling on the VRMs.

Drop multiplier to 13.5 and raise FSB a bit higher. Sometimes you have to fool around with these to get it just right. Don't forget about your NB frequency and keep your HT Link as close to 2000MHz as possible smile.gif

For anyone saying I should raise the multiplier, please keep in mind that this isn't a black edition processor. (Also, I maxed out the timings. No difference.)

For reference:

I have a (my second) 1055T that is running 3860Mhz @ 1.3875v (BIOS) which drops (vdroop) 1.35v under load. So I'm guessing you should shoot for some much much much lower voltage. The CPU/NB is running 2574Mhz @ 1.25v (BIOS).

The chip/board are 13.5x286 w/ DDR3 1600 & Xigmatek S1284 (CPU cooler) with temps maxing (cores with +13 degree offset w/ CoreTemp) at 49c (which may not be any more accurate than the socket temp - maxing 45c~).

If you have LLC on your board I would maybe suggest checking out it's options and trying to narrow down a more moderate voltage. You can also do something else:

You can install AMD Overdrive with the BIOS returned to stock (or whatever AMD Overdrive requires the BIOS to be set to for initial functionality to overclock via Overdrive in Windows) and read the AMD Overdrive Phenom II Overclock guide (I'll find the link in a few here and edit) to overclock. So basically you can manipulate the clocks in Windows and see what you can get going, then once you've found out how far the chip/board can go you can then stop using AMD Overdrive and pop the stable settings manually into your BIOS. redface.gif

You can't raise it, but you can lower it in .5 increments. Lowering to x13.5 and raising the FSB can help achieve a higher overclock.
