I did some NB clocking and its at 2424 Mhz. I got a set of nice Corsair XMS 1600 ram from sigma, its at 9-9-9-24 @ 1600 clock.

Tighter timings or relax and push more NB? Which is better?

You'll get more from NB versus ram. I would try to get the NB as high as you can and then play with the ram afterwards.
As for the ram if it's 1.5v you can probably just up it to 1800-1866 at stock timings and more voltage.

Check Sigma's post, I think he sent me the later version of the ram.

Had I known that ram can clock like mad I would have got both the sets lol. But I didn't have the ECS + 4130 when I bought from sigma.

Ok I will see how far I can go on the ram.

Is NB clocking still effective on Bulldozers? I heard PII gets the most kick from NB clocking.

 

[Johan45]

NB clocking will improve ram performane and cache latency. Here's an example of my CPU with a high NB clock. Aida 64 is a good tool to check Ram and cache performance you can use it free in a trial version.

I was told yes, up to about 2600-2800 depending on what your chip can do. This was before I knew my board was a turd and wasn't happy playing with NB frequencies, lol.

Damn that rev3 !!
It does scale even higher if your CPU is capable and you can keep it cool. The voltage get a bit high for faint at heart.

My gigabyte board does not tolerate even the slightest HTT or NB clocking. It will work but after couple of sleep and wake up sessions it goes into coma! So far this ECS has behaved well. Tempted to try the 8320 on this board.

Dumb thing this ECS does is to over volt both CPU and Memory, if it happens the same to the 8320 then managing the heat will be a problem. ECS retards need to fix this issue (on both their 970 and 990fx boards).

BTW what is the default volt for a FX 4130?

 

[Johan45]

Don't know all FX have different vids set from factory. CPU-z will tell you in a txt log. Set CPU to default in bios and use the about tab on cpuz save as a txt file and you can find it in there.

 

[suraswami]

can't clock to 2.6 Ghz on both HT and NB, board freaked out. I will have to work on Ram speed now.

The cpu sensor on my M5A99X Evo R2 reports 72c, while Core Temp with an offset of 10 reports 60. Running an 8350@4,5, which do i trust? D:

Download and install HWMonitor free will onlt take a minute then while you have it open run P95 or whatever stress test you're using. You'll see a CPUTIN near the top that will be the socket temp of the board and lower down you'll see a package temp which is the CPU cores. I think you may be seeing both with different software. Just make sure you don't have any other Monitoring software running.

Got it stressin', will u/l screenshot in a bit.

And here's the result:

Edit: it ramped up to 74c CPU/52c Package before i took the side panel off just to be sure

 

[Johan45]

OK you CPU / socket temp is 72 and the core temps are 51. The 20 difference can be reduced to give you some haedroom. Because of the FX 8XXX power draw it will really heat the VRM section. Now your board is on a 6 phase board so it has to work just that much harder to feed the CPU which in turn causes more heat. Some things we have found that can really help that and bring the CPU temp down to around the 60 mark is fans on the VRM Heatsink like this


And a fan on the back of the motherboard behind the CPU like this

Bollocks, i'll have to find myself some little fans then.

 

[Johan45]

You're probably fine the way you are unless you want more of an OC from that thing. 4.5 is a decent clock for air cooling and you're not likely to get a whole lot further.

Thing is after Priming for a while, one random core drops out, with an illegal sumout error. Also, removing my side panel intake took it d0wn to 72/73 cpu instead of the 73/74 it maxed at first, but more dropouts. I think that's the VRM issue you were talking about.

Edit: Speaking of dropouts, it just happened.

Edit2: On two cores, even.

 

[Johan45]

Well it could be part of the issue but it's heat that's the problem and probably a bit low on core voltage. You probably should see if you can scrounge up some fans. I know there's one on the original heat sink for the CPU that you can strap on the back of the board. I just used double sided tape for that. See as the CPU gets warmer it needs more voltage which causes it to get warmer which .... see whaere I'm going with this. At this point you need to cool it since you don't really have the headroom for additional voltage to stop the cores from dropping.

I already upped the voltage a few times but that left me where i am now: stranded. I did find a 50mm i'll try to glue to the VRM sink(which is connected to what seems to be the NB via a heatpipe, so that might help both actually)

Edit: Nevermind, it seems i'll need better glue first since after a minute or two i found my fan breakdancing on the GPU

Double-sided tape. Doubles as a vibration dampener
BTW, yeah, having your VRMs attached to the NB via a heatpipe, definitely need some extra cooling there.

 

[Johan45]

Ya it can be tricky at times. Double sided tape works. It may not necessarily be the CPU Core voltage that's at fault here. Have you set any other voltages or any LLC settings at all. What is your ram and NB speed. Could you post up some CPU-Z shots of the memory and spd tabs?

I'll have to buy some when i feel like getting off my ass for once

I don't remember touching anything(i accidentally OC'd FSB instead of CPU once, but i did a CMOS clear after that.) Anyway here are your screenies:

Dude you really need some new RAM or atleast try OCing it

 

[Johan45]

Well I have a few suggestions for some settings in the DIGI section of your bios. The CPU and CPUNB LLC set to high from auto. Now you may need to bump the CPU voltage a bit after this to get back to the almost 1.4v under load. Also your ram timings seem to be a bit high but that really shouldn't cause instability. I would also set the ram voltage to 1.55v though. I've been helping a few lately with kingston ram and having some amout of difficulty to be honest.

JEDEC 4: 1333 9-9-9-24-33 @1.5V
Running at: 1336 11-11-11-28-33
WTF? Were you having issues running stock speeds? That chip should be able to run 1866 CAS 9 or 10 with very little work, more if you put the effort in.

 

[ypoora1]

I don't think this stuff will OC at all without heatspreaders and being 8GB per strip. I would repalce it, if i had funds of any kind.

I remember changing those, but i'll look into it.
