***official amd 83x0 overclocking thread***

On a slightly separate note, I searched and couldn't find a definitive answer to this. At what point do these chips start to degrade with voltage. I don't seem to be totally thermally limited at 5 GHz but I would need more than 1.51V to get more. What is the safest max people have tried? Any fried chips that we know of?

I've pushed my chip to 1.59 :eek: in an attempt to get stable 5Ghz, chip is fine. and currenly have my NB @1.45 v as set by my mother board for extreme OC. My NB is @2600 though.

Here is a guide to AMD FX overclocking, is a good guidline to what these chips will take.

Shes all settled at 4.8 24/7 now at 1.51v Rock solid stable. :D
 
Just ordered an XSPC RayStorm 750 EX240 kit for my CPU. Be good to see how far this will let it be pushed and see if it's much better than high end air.

Nice one, be interested in what temps you get with that raystorm, I'm using a chavy EK lite from 2010 and I like the look of the raystorm.

Ordered a full cover block for my 7970 matrix too to add to my loop, although I will be adding another rad and pump into it.

This is what I have on my 8350 m8 @ 4.8 with 1.44v it idles at 27 socket and under prime its maxed at 56 socket, 45 core I have gentle typhoons in push pull on rad and all case fans are also typhoons gaming it hits 37 core I also have the vario d5 pump @ setting 4 out of 5

What are you using to monitor temps with?

I have inline temp sensors for coolant temps and I use a fan controller wiith temp sensors and speedfan hw mmonitor there all within a degree of each other

Edit I also have a 120 fan mounted in side panel blowing on rear of mobo socket and fans over nb and vrms and my dining room is also cool

This has taken me all day!!!

18 month old baby girl taken up segments of time, I have a sheet wifi connection, robbed the PSU out of old system which took ages to unclip, unwrap, de-dust etc.

No cd drive so things I forgot have to be downloaded to laptop transfer USB yadda yadda haha!!

Anyway almost there now so will update some pics for ya! :)
 
Hi all

This thread was awesome so I upgraded from my cheapo 4+1 970 board to a Sabertooth as well as a noctua nh-u14s. Hugely impressed with both! The noctua is a huge improvement over my old titan fenrir.

I am currently at 4.5ghz @ 1.404 VCore - stable after 3 hours of AIDA64. Playing BF3 this is about as fast as my (dead) 2500k at around 4ghz. Even the pathetically single threaded NS2 feels pretty good.

Until I got to this level, I was running p95, but my temps quickly ramped up to the point I think I am at the at-risk point in terms on temps while running prime. I was getting 60/61 on the cores, even at 1.392 vcore (which crashed after 1 hour of prime), so I have switched to AIDA64 as I pump in a few more volts. Is that normal?

In contrast, AIDA64 CPU stability test maxed out at around 48C @ 1.404 VCore.

Are the volts typical for these chips? They feel low to me as I keep seeing people saying 1.45 and above?

I had great difficulty attaining any form of stability at 4.6ghz, I went up a good few notches of vcore (to about 1.42) and crashed after a few minutes of AIDA. What should I be expecting?

The main issue is thinking of AIDA vs prime. I am concerned that the lower temps in AIDA are suspicious and it is not putting enough stress on the chip. A few hours of gaming and I reached temps not far off AIDA. Does that mean I may still be unstable after doing ok in AIDA?

I have so far kept the CPU/NB voltage at 1.200V. Does this need to be increased as I increase the bus freq?

Any tips for getting up to maybe 4.8ghz without setting the house on fire?

For reference, my current settings are:

- Usual power savings disabled.
- 20x CPU mult.
- 225 bus.
- DDR running at 1499mhz effective (I can't POST at the next notch up with default timings).
- Very high CPU LLP.
- High CPU/NB LLP.

Some stats on my OC results below:

Thanks everybody!

Got ya new bits then m8 working away atm only pop on now and then on phone. The joyous task of building new rig lol what cpu did you get after?

First welcome to the nut house ;)
Prime will always push the cpu hard these temps are normal especially for air m8 small fft are a killer

Lower volts are good all chips are different lower gives you more head room to clock dont complain lol

Aida doesnt push cpu as hard as prime unless u just run ftu or fut alone which will toast your chip.

Yes up the cpu/nb as you up fsb a lot of people have found a mixture of multi vs fsb are good for these chips for example I have 21.5 multi and 215 fsb at 1.44v

To go for 4.8 high end air is able even at 5 but for good temps h100 or custom water loop is recommended

Aida temps are more real world temps I.e what your gonna see gaming so there fine also up the vdda voltage which I found helped with stability a lot think im running 2.65v its 2.5 standard
 
Yeah the AIOs tend to work better than air coolers. I think I know why, too. The contact plate on a Noctua NHD-14 is smaller than the surface of the 83x0 and the die itself is loaded with a dual core module in each corner.

Even the H60 couldn't hold a 4.2ghz overclock Prime stable for me.
