M3A overclocking

[Methious]

I hear ya I tend to stay close to stock vcore on Amd, higher volts on the X2 series doesn't yield that dramatic an increase in speed for the price you have to pay in heat. I might push a little more volts now that I have the new Swiftech triple 120 radiator installed an leak testing. Only for testing though 24/7 stock volts and what I can get from there.

Asus has never responded to me!

I am going to ditch this board. I will put it and the Phenom on Ebay this weekend. I need the money from one of my boards/cpu, and:

It is good with the x2, but I have to run 3.25@1.525v to equal the same benchmark scores I can get with 3.15@1.45 on the old board. My old board won't run a Phenom and most Phenom boards are not worth the money...at the price I could nearly buy a Blood Iron and q6600.

So I don't have much choice, keeping the M3A seems to be a gamble. My x2 will live longer with the old board and that is that.

So you contacted their developers directly and never got a response? May I ask what you old mobo is?
Yep it really is a gamble, first I had to wait around five weeks till the board got delivered and now I have to wait till the bios matures.
I wonder if this voltage thing is a general limitation of the 770 chipset. The phenom 9500 itself has a upward locked CPU VID at 1,25V. VCore settings rely on the CPU-VID settings (atleast on the MSI Premium mobo) so an upward lock on cpu-vid should cause an upward lock for cpu-vid also.
But it seems the 1,25V upward cpu vid lock is no issue on the 790FX chipsets, they can apply higher vcores there.
Can understand you decision to sell the phenom I have no use beside exploring specs for him too. Damn I don't like to say but an wolfdale at 3GHz for an similar price would do a better job here, 4GHz at ~1,35V are not bad.

For me (and I think it's a personal choice) running my 5000+ BE
on stock volts @ 3.00G was/is better then running it @ 3.2/3.3 with 1.55+ volts.But hey it is xtream systems after all

Yep, glad to see this thread did not get closed due to bad oc results.

Must say I liked the feature on the m2a-vm which allowed two nios profiles to be saved. Id like to have two profiles, one for normal work (may be even underclocked for lower power consumption) and one for heavy workloads.

Here is a comparison of bandwidth in ganged vs. unganged mode.




Memory timings are identical with KTE's, the only difference is the cpu multi 11 (9500) vs 11,5 (9600BE).

Everything but the chipset/board are identical with KTE's testing on the MSI K9A2 Platinum.

Fixed!

Exactly!
If you place 000 or 1.550VID on the CPU with very good cooling and it only gets X MHz, you won't get more because it's a chip limit and that's 1.536VCore you're feeding it.

I was afraid you would say that.
I'll call of the hit on Asus Bios team after all 1.7v for cpu and cpuNB is plenty.
Guess we were hoping that there was some "mysteries" core logic (as AMD calls it) setting that was missing from the m3a bios. I haven't given it that much yet,(1.7v)
trying to "break it in" sort of speak -like a new car or a virgin- lick it before you stick approach.
We could use a voltage control for theCPU HT setting, as Justapost can get it in the 270 range.
