Phenom II x6 1090T: Won't hit 2.6GHz CPU/NB - Page 2

post #11 of 19
Thread Starter 
If you mean the P-States: Every P-State has its own CPU/NB VID, yes. But they are all set to the same value per default.

you get better mem bandwidth and reduced latency if you just tweak you rams instead. much easier and much better gains.
I can't tighten the timings, CL7 is the best these chips can do, even at 1.5V and 1066MHz (pure nonsense, I know that, but I just tried it for the sake of trying it out). I might try going for 1600MHz instead, but.. is that really easier to achieve? Haven't done that before, but people claim the phenoms don't do that so easily.

you can go for 1.65v , stock vdimm for amd memory controllers. wink.gif

If those states are using less than needed voltage for your wanted 2.6GHz, could you change them? As far as I know, the speed does not change, so using the default(s) might be unstable.

I'm already overvolting it via the offset voltage, otherwise I wouldn't even be able to boot at 2.6. The offset is actually added to the states' VIDs, and since they are all the same (1.15V.. plus the offset specified in bios). Raising them would only result in even more voltage.

Jayflores: Nah. My memory's stock voltage is 1.35V, I don't think pushing it by another 0.3 would be any good.

Why use offset? I use manual. I have M5A97 PRO. Offset just messes things up as it overvolts it from P-states

ddr3's can handle and will not fry @ 1.65v hehehe

There's a few things that you could try, but it seems a strange thing that I have not come across before, leading me to think that its not the CPU/NB that's causing you're problems! Anyhow... I found it best to try and keep the HT as near to or just below 2000 (seems like you are doing this ok) and you should be able to get at least one bump or two on the CPU/NB at stock voltage as the thuban CPU has a much stouter NB than the Deneb phenoms and can regularly make ~3000 CPU/NB, I would say roughly 1.3v is where I would like to be for 24/7 running. The CPU/NB will help with your memory performance and thubans imc should be able to cope with anything that your ram can do and more, you can change the ram speed from within the bios using the ram ratio/divider and that should give you a indication if the speed you are setting it at before you save and exit, if you look at the spd tab on CPUz that will tell you the timings and voltage needed for a specific speed, as you have a LV set of ram you may need to bump the voltage to run it faster. The NB (motherboard) should be left alone and only needs adjusting if you are using the reference clock (fsb) to overclock and are reaching a high fsb where extra voltage to the NB chipset on the board is needed to stabilise the overclock. As I said earlier I'm not sure this is a CPU/NB issue as you say it will prime and game ok and then randomly shutdown, seems like it may be a OS problem, but it is strange that's for sure.

Hey, thanks for the reply.

I played around again, now I've set it to 2600MHz again, voltage to 1.325, HT frequency to 1800MHz and NB/HT voltage to 1.25V - no crashes so far (Valley + Prime still running). Maybe, maybe this will finally work. RAM is still at stock clocks and timings (well, almost... 1T instead of 2T, but if that were a problem I'd already have noticed).

I'm going to keep this setup for a few days, in case it's stable (e.g. it doesn't freeze any longer), I'll try lowering the voltages a bit. Thanks for your help wink.gif

Hi everyone!

@ VikingGe:
Maybe a bit off-topic, but as far as my experience with AMD goes, not too surprising:
I had to get my FX-8350 stable via adjusting NB HT voltage too. It just would keep on having errors with prime95 FFT otherwise...
Seems like this is rather common... Many OC guides mention, and rightly so, CPU/NB, maybe also VDDA, but not too many recommend adjusting NB HT voltage. In my case, and it seems hopefully in your case too, it did solve the issue of not being stable at high clocks.
It took me a while to figure this out oO just because I didn't really think it was the issue biggrin.gif

Hope this helps someone like me going forward! smile.gif
