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

Very nice. Hope she enjoys :cool:



Nice going Thont mate. Looks like a nice 1866MHz with decent clocks.

As an experiment, I put 2 sticks of my X79 G-skill Trident X 2666MHz (CAS 11) memory in my 8320 system and thought I'd run it at 2400MHz at the same timings I use on my 3930k (10-12-11-30).

Here are the Cinebench results at 5.15 GHz. Score of 829. As we can see, the memory bump does have a small role to play in increasing the score as my score with the exact same OC but with 2133MHz G-skill Ripjaws Z at 10-11-10-30 was 816. Haswell IMC is much stronger and would allow DIMMs to reach 2800+MHz.

I'm no whiz at tuning memory but I don't think a score of around 850ish on cinebench R15 at 5 GHz on the 8320 is beyond possibility if one can be bothered to tune the memory with FSB to reach 2666MHz +. Not too shabby.

Here's a pic:

Might be able to score a little higher with W8 too.

That's a crazy score though.
I think it's the highest AMD score I've ever seen under conventional cooling.

8.1's out tomorrow if you can find a cheap 8 code.

Thanks. Yes I have W8 on some systems at home but it is only the "upgrade" version. On my main systems I have only used win7 ultimate but thinking of just buying 8.1 to do some fresh installs.

How do I do this?

There is a button on top of the block/pump. Push it so that all 3 lights are lit. That should give you "performance" mode.

Lets hope it has gone to the Cinebench thread to ruffle a few intel feathers! :p

I haven't actually posted it there. Will do!
 
I ran the Corsair's fans at full speed once. I had to check my nuts to see if I could still have babies after.

IE - the noise will make you want to cry. They're soooo loud at 100%.

Isn't there a button on it physically?

You can also connect the fans to motherboard headers.

Already got three case fans using mobo.

As with Martin above, surely that's stupid as I have the case side on... :confused:

OK not too much of an issue as I only reach 50c with it on current half speed setting. Now I know I got 10c to play with I will press a bit more.
 
The fan header from the H100i can be used to control the fan speeds can't it (Assuming you've connected it) but I'm guessing, as otherwise I see no point for it (Maybe pump speed)

Just whip off the side case and push the button, then go "Yeah, that's too loud" and put it back to normal ;p

It shouldn't make a massive difference. I dropped mine to 7v in the end (I don't have them connected to the block as it looked untidy).

But yeah, all that noise made hardly any difference once the loop had warmed up and settled in.
 
When I had an H100, I swapped the standard Corsair fans to Akasa Vipers and even on 100% duty, they were quiet but shifted huge amounts of air. Hence I kept it to performance mode all the time. I imagine it also controls pump speed. The H100i has some sort of software control does it not? Thont you don't have the "i" version do you?
 
Latest bench:


Going higher starts to show instability. No BSOD or anything but apps don't like it so this is where more tweaking is in order to go higher. I put 1.49 vcore, so probably showing the 8320 ceiling for stability around 4.8 but there's plenty more tinkering to mess about with.
 
Stage 1 prep. Just had a spare standard AMD backplate drilled out to take the EK CPU block fixing bolts. I don't know why EK omit this plate, well I suppose I do, cost. I would not like to clamp it up without a backplate.
I may be up and running this weekend, but it is more likely to be next
 
I'm still jealous of not having an 83xx set up, it's getting worse.

As to Cinebench, it's obviously a rounded benchmark, but it's not the be all and end all of multi-threaded benchmarks. Povray is a good second one, but it doesn't have any fancy results screen like this.

e.g. this one shows the 4770K and 8350 at stock being dead equal:

yeh I swapped my H80 fans to Noctua NF-P12s and now run it full speed 24/7 with the same noise as the standard fans on low. Knocked 8 or 9° off temps.
