Post your AMD FX-8350 Overclock

[Greenlepricon]

Ooh, look what came in the mail today

And my Crossfire V Formula-Z is a Rev 1.01? I don't know if that is good, bad, or meaningless. Downloading the latest BIOS and win7 drivers now.

Looking forward to this! Hope your magic works for AMD as well

 

[inf64]

There are minor differences between revisions,you are set. I think your shipping BIOS already supported FX83xx but it's best to have the latest version.

Good luck with overclocking .

Yeah ASUS doesn't mention the different rev's on their website, which is sorta odd, but oh well it works for me

Downloading drivers...and...WTH!? The AMD chipset driver is 923MB?

I'm on cable DSL and my estimated download time remaining is 1hr 17min (asus download servers are not exactly lightning fast, which isn't usually a problem because chipset drivers are usually 10-15MB, not 100x that D

Why is a chipset driver package nearly 1GB? Is it loaded with a bunch of APU stuff that doesn't relate to AM3+ mobos or FX processors?

Yeah it's beyond obscene that they have rolled all of that crap together. I love the AMD GPUs I've used, but the mainboard chipsets are still suffering from poor SATA/USB performance compared to Intel, and the driver structure is atrocious. They could really use some new programmers to do a better job de-crapifying the chipset drivers. You can manually get a set made of just the raw drivers, it's what I've ended up doing in the past, avoiding AMD install manager or whatever that was, CCC, and all the other garbage I don't want on my system.

Get this :

http://www2.ati.com/drivers/12-10_vista_win7_win8_32-64_sb.exe <--- katest 9xx AMD chipset drivers

then get whatever special drivers apply only to your particular mobo (gbit lan, 7.1 audio, 3rd party USB3, whatever)

If want raid drivers for 9xx : http://www2.ati.com/drivers/12-10_vista_win7_win8_32-64_raid.exe

Oh that is MUCH better, 20MB download FTW :thumbsup: Thank you

 

[sequoia464]

Interested in how well that ceramique2 works for you - all I had when my 8320 arrived was an old tube of the original ceramique that I used until I got some PK-1. I had about a 2-3 degree diferrence for the better with the PK-1.

Of course part of that difference could have been application technique - I struggle a bit with the ceramique - usually have more of it on me than the CPU.

 

[skipsneeky2]

IDK,looking forward to your results.:thumbsup:

Been lusting for a while for a processor to overclock and tinker with,my i5 2500 non k is dreadfully boring housed in a h61 mobo and the 8350 actually has crossed my mind a few times.

Might almost sound stupid switching over but damn the idea of a highly overclocked 8350 does sound pretty fun.

I have read that you should avoid using the AMD chipset driver. I am running the default MS drivers and everything is A-OK. I also tested my SSD just to be sure that for example SATA speeds are fine with the MS driver and everything was good.

Only the AMD Sata Driver. Keep the MS driver. Otherwise I install all other AMD drivers. There is some issue as to whether or not the AMD sata driver supported trim.

What is pk-3?

This SATA driver is controversial, I have used the AMD drivers for the last 18 months or so. Not that I would notice in real life, but the last time I benched a SSD the results were better with AMD's drivers. It's been a while now so I don't really remember the margin. Not huge as I recall though.

I know that they are supposed to be trim friendly (since the 10.9 drivers) but hadn't heard that there might still be issues. I have been running everything in raid0 until I switched over to W8 so I hadn't really paid any attention to trim. I'll have to check it out.

Not directed towards me but I also appreciate the heads up on the SATA drivers.

Doh I already installed the AMD SATA driver.

I'll have to keep an eye on my crystaldiskmark scores to make sure trim is working for me.

 

[SnooSnoo]

I have an old 790FX mobo with an SSD as boot and some other 5 drives for storage in RAID. Obviosuly I had to use AMD's drivers in that configuration. To check if TRIM was working I tried this: "fsutil behavior query DisableDeleteNotify". If the result is '0' TRIM is enabled. The result was 0 for what it's worth.

I've got my FX8350 up and running, everything is just stock right now, but I've got some questions.

What are the official AMD specs for max voltage and max temperature for this thing? I've searched high and low on the web but all I can find are generalized specifications that are nothing official.

I've looked on AMD's website and if they have technical electrical specs then they elude me.

 

[AtenRa]

IDC,

I will suggest up to 1.5V or 1.55V and max temp bellow 60-70c. Usually you will not need more than 1.5V with air/water. AMD CPUs are very resilient with Voltage but they have lower TJ max than Intel CPUs.

I havent installed my 8350 yet but i will help you with tuning/settings in a few days

ps: for a bench session you can go higher

Short answer: http://products.amd.com/en-us/DesktopCPUResult.aspx

The real answer is that both Bulldozer and Vishera do not specify max voltages, and Vishera does not even specify max temps. Thuban, however, specifies both (as well as all other generations behind it).

Thuban - operating voltages and max temps.

Bulldozer - max temps, no operating voltages

Vishera - no useful info at all

During the Deneb era (and it was updated for X6, but only very few pages were affected), AMD published a "Dragon Platform" overclocking guide, wherein they specified 1.5 - 1.55V as max voltages for on-air overclocking. This is the figure that overclockers quote, I am not really sure how to interpret it because it comes with hefty disclaimers and no warranty from AMD (despite publishing such a manual). For reference, Deneb and Thuban only specify operating voltages of 1.4V (Thuban and C3 Deneb) to 1.425V (C2 Deneb, the 140W Phenom II X4)

lol I think it is funny that at the top it says AMD FX 8-Core Black Edition and at the bottom it lists black edition - No.

Also L3 isn't listed I wonder if amd without thinking fired the people who write the documentation so they went to the zoo and adopted some monkeys for office workers.

That's probably not too far off the truth. In all likelihood, their doc team is pretty much a skeleton crew now, and with other (probably more important) responsibilities than updating such docs, with these types of public-facing docs more of a bullet-point/checklist type of task that does not really get reviewed or affects their annual performance eval.

Their last add-on to the Deneb X4 line (980 BE) suffers the same problem in documentation as BD / Vishera, even though this chip has absolutely no difference from the 965 C3 other than binning. It just shows you that by that time, updating these docs have become a much much lower priority in the "things to do right" department.

Idontcare: Here are my AIDA 64 sensor specs for my 8350 running at 4.53Ghz (21 x 215). I set the LLC to ultra high, vcore to 1.4437 and tweeked some other settings.

My overclock is not radical. I had my vcore to 1.513 and could boot into win8 and run programs fine but when stress testing the temps were too high for me.

I have a Asus Sabertooth 990FX rev1 mb with the latest BIOS and it is a very good mb BUT you bought the top Asus mb so I expect you will be able to tweek higher.

I found 4.5 Ghz to be a happy medium. Solid chip for the $$.

Hi guskline,

That does seem like a very reasonable everyday OC. What's the load temp on that under IBT Max or whatever your hottest stress test is?

 

[guskline]

jvroig:Sorry for the delay. I just ran IBT Max for 14 x to get the peak temps and averages.

Peak overall CPU was 57C while most of the run it was at 52C. Peak core temp 51C while most of the run was 44C.

Peak NB was 62C.

As I said above my voltages and settings might be a wee bit high but I want to assure 100% stability so I had this setup run 1 Hr of the AMD OD stability test (all components stressed) without fail, 1 hr of OCCT without fail and a 20X run of IBT without fail.

Also the temps NEVER exceeded IBT temps above for the AMD OD run or the OCCT run and frankly were somewhat lower.

For me it's a good setup. Are there others running higher? Sure, but I notice that most of the real high clock speeds are using a custom water cooling system. I have a Corsair H100 with 4 fans which is a decent cooler. My reading of forums gives me a sense that the true high end custom water cooling rigs ( including the cpu and vrm cooling) result in the highest STABLE ocs. Hope this helps.

 

[jvroig]

57C peak at a test that simulates a load you wont encounter in real life is great :thumbsup: Thanks!

By the way, just curious: does the BIOS still allow you to disable cores at will, for example to have only two cores enabled or such? It's been a staple for most boards since Deneb, just want to know if BD/Vishera still has that capability.

 

[AtenRa]

With ASUS Crosshair V Formula you can disable cores but only in pairs. 1 and 2 or 3 and 4 etc.

Edit: You can disable Modules not Cores individually.
I had a beta bios last year that i could disable individual each core within the Modules but it had some problems with certain applications.

 

[jvroig]

Really? That's still fine, although that does limit your ability to try to give an entire module's resources to one core only.

I thought I read somewhere sometime that AMD recommended reviewers to also try to disable odd-numbered cores in the bios while testing OC stuff, my interpretation being allowing modules and cores to become more or less the same thing (1 module=1core).

Anyhoo, thanks for the info, Aten :thumbsup:
