AMD Phenom II X3 700 Series OC Club - Page 544

post #5431 of 6432
I hate having to run the chip over 1.5v

I settled on my 3.5ghz @ 1.39v because I like the low voltage.

I haven't been able to hit 3.7 stable using multi @ 1.5v and I don't want to rack voltage into it just to get another 200mhz.

I haven't had time to massage everything else to see if I can get above 3.6 without going over say 1.45. I'd like to get to 3.8 or above, but I just don't want to keep the voltage that high.= and probably have inadequate cooling for that much voltage. Although I don't ever really top out above 50c.

i started a new oc from scratch and something is really odd, i just overclocked via the multiplier and everything goes as expected till i hit 3.4ghz (17x200), every now and then i have to increase the vcore a bit to get the higher multi stable but everything above 3.4ghz seems to have no vcore relevance, even if i go all the way up to 1.55v@3.5ghz it wont be stable. so my guess is that either the ram or the nb is the problem.

i have my ram all the way down to 9-9-9-30-42@1.65v (also tried 1.7v) and CPU-NB VID is increased by 0.1 (1.3v). the ram timings/voltage did nothing at all when it comes to stability, the CPU-NB voltage gave a bit stability, now prime95 doesnt bsod anymore on blend test but gives rounding errors after a while.
EDIT: did a 10 hour memtest today without errors.

someone ever encountered a behavior like that and can help me with this problem?
what could cause this oc wall @3.4ghz? im happy for every suggestion/idea how to break the wall...

here is what i tried so far.. (the newer tests are on th left side)

Using multi...

I hit 3.2 without increasing voltage.

I can get 3.5 with 1.39v

I can't get 3.7 with 1.55v

do you need to change anything else than that to reach 3.5ghz "stable" or can you just increase the multi and vcore do get there?

edit: is that with 3 or 4 cores?

Hey, I got some quick questions:

On my mobo, I set the vcore to 1.375 in the bios, but in HWMonitor, it shows up as 1.41. Which one is correct?

Also which is better:

Quad @ 2.9 GHz or Tri @ 3.5GHz? (I use the PC for Gaming only.)

Unfortunately, my 4th core isn't very good, so I can't OC much with it enabled.

You can't really compare the two like that.

In gaming, unless the game is specifically written to utilize 4 cores, the tri core will perform better at higher clocks (generally). However, the quad core will probably perform better at encoding MP3s because it will have another core to dedicate to an encoding operation.

It depends on more than just cores and ghz, but generally speaking a tri and quad core are going to be about the same depending on the title. More and more, games are being written to utilize more cores.

Clock speeds shouldn't be negated though. On a budget, a 3ghz dual can get a lot done.

Keep 4th core at 2.9, OC the other 3 cores to 3.5

Hey add me to the list.

http://valid.canardpc.com/show_oc.php?id=950229

HTrefClk: 200
Multi:18x
CPU-NB:2600 MHz
RAM: 1600 7-7-7-21-28-1T

Don't know why it wouldn't validate, quite possibly that I have mix matched GPUs' in that one (9600 GSO for PhysX).
