Post your AMD FX-8350 Overclock

[guskline]

Got mine cranked back to 4.536 Ghz (21 x 216) with some increased vcore 1.44v and other tweeks. Still runs very cool and ran 1 hr OCCT and a 10x IBT without a problem. Max overall CPU temp 54C overall and the core temps never exceeded 49C.

I monitor temps with mu licensed version of Aida64 which appears very accurate. I could go higher but the power usage and heat start to creep up to levels that are not worth the extra clock rate.

I'm finding that the PileDriver takes some tweeking to really get it to pop.

What tweaks would that be? Do you mind posting your exact relevant settings? (vcore, HT/FSB, CPU-NB multi and V, etc) Thanks.

Be glad to do it later today. Was just summoned by my wife to go Xmas shopping. When the Supreme Allied Commander calls I jump!()

 

[Durvelle27]

What water CPU cooler are you going to get and what TIM do you use at present?

i use Arctic Cooling MX-2 and i'm looking at getting a Corsair H70 or H80 as a H100 won't fit my case

 

[Durvelle27]

Hopefully u get reimbursed for that garbage.

No worries I was a 990 owner, like two years ago .... then I asked myself why I'd buy a board capable of sli on CPU's that bottleneck even a single GPU. Two years later and the same question is still valid. Who cares about OC there's a million and one reviews on the matter, lets see some dual GPU results. Can't wait for IDC to engage the thermal shutdown on that thing as im sure some of you already have but neglect to mention.

Why did you link that set of benchmarks? What were you trying to prove? They clearly show how well the FX83XX series do for performance considering their respective costs compared to SB and IB processors.

I was referencing performance, not power consumption.

What difference does a few pence make each month anyway. At least AMD is providing Intel with some form of competition.

When you take into consideration intels conservative clocks they're really not. I'll leave this thread be.

Do you see the purple line(FX8350) ?? do you see when it finishes the job at 900 secs and gets idle??
Now, do you see the 3570K needing 200 secs more to finish the same job.??? that is 22,22% more time to finish the same job.
Your 2500K needs even more time to finish the job[/B] (close to 25%)

Lets assume that FX8350 needs 120minutes to finish the job, that means that your 2500K will need an additional ~30 minutes more.
I could shut down my PC (ZERO power) and you would still consume power for ~30 minutes more.

Suddenly it seams that your 2500K is not that much more efficient than you thought it was

Let's stop all the threadcrap and off-topic bickering.

This is not an Intel vs AMD. This is not even a review thread. Let's have some OC results, OC settings, OC discussions. No more threadcrapping.

BD231: yes, please leave this thread, let it be, you should not have entered it in the first place, that much is clear.

Gusk, Durvelle: those OC settings, if and when you can provide them, would be appreciated. Thanks.

Okay jvroig, just got back from the shopping trip and went into the BIOS of rig 3 in sig below to copy all of the pertinent Info.

Here goes.

The Mb is an Asus Sabertooth FX990 Revision 1 with the latest BIOS -1604 -dated 10-16-2012.

Under the tab AI Tweaker the following settings:

AI OC Tuner -manual
OC Tuner - Cancel
CPU Ratio - 21
AMD Turbo Core Technology - disabled
CPU Bus Frequency (Fq) - 215
PCIe Fq - 100
Mem Fq - DDR3 - 1720 Mhz
CPU/NB Fq - Auto
Ht Link Spread - Auto
CPU Spread Spectrum - disabled
PCIe Spread Spectrum Auto
EPU Power Saving - Disabled
Dram driving & timing control - Auto
CPU Load Line Calibration - Ultra High
CPU/NB Load Line Calibration - High
CPU Current capability - 130%
CPU/NB Current Capability - 130%
CPU Power Phase control - Extreme (full)
CPU Voltage Fq - manual
CPU power duty control - T. Probe Thermal
CPU & NB voltage - manual
CPU Voltage - 1.44375
CPU/NB Voltage - auto
CPU VDDA Voltage - 2.55625
Dram Voltage - 1.525
NB Voltage - 1.125
ALL other settings in this subsection are set to auto

Under Advanced / CPU Configuration Cool& Quiet, C1E, SVM,Core C6 state and APMmaster cell are all disabled.

CPU core on/off unlocker is enabled

Active cores is enabled.

Under a memory setting I disabled ECC memory.

Sorry for the long list but hope it helps.

In Aida 64 the bus reads 216. I think these mbs slightly OC from the setting. I mentioned that at MAX CPU stress my overall CPU temp never exceeds 54C and the individual cores never exceed 49C. As I am typing this the overall cpu is 31C and the individual cores fall to 12C

won't be able to tell you yet as i don't remember and my pc doesn't have a video card right now so i can't look an see as the AMD 9 series chipset doesn't have onboard graphics

Ht Link Spread - Auto

Would you mind checking what the HT link actually got set to for you, I tried the auto OC, checked it in overdrive, and the HT was set around 2380.

This is with a sabertooth also but using a 8320.

 

[guskline]

Yes, my HT is set at 2373

 

[guskline]

Changed back to 4500 (22.5 x 200) to keep the fsb at the 200 level. Had to bump the vcore up a wee bit but all runs solid. I'll fool with this a little. BTW, if I upped the vcore to over 1.51 I can easily boot into Win8 at 5 Ghz but heat too high when running stress tests such as OCCT. I have my H100 set for middle performance. If I crank the fans to way high I might drop a few degrees but the sound!

I think to get extreme OCs with this chip you need a custom water cooling system that includes the cpu, vrm etc. to run at those speed STABLE. I kind of chuckle at new 8350 owners who say they can boot at 5 Ghz etc with normal air cooling and when I ask if they can run stress tests there is a deafening silence.

I'm more conservative. I want to know that the speed I'm OCing to will hold up at the outer limit stress testing or after an hour of hard gaming, not just booting into Windows and "validating"

@ guskline

You are right,~5Ghz OCs need more extreme cooling and power draw jump is prety large. The sweetspot for Vishera owners seems to be 4.6-4.7Ghz on good air/WC with medium Vcore bump. Performance is noticeably higher vs stock and power draw jump/temp. jump is acceptable.

In my case the "sweet" spot apears closer to 4.5Ghz. I had it at 4.6 Ghz but the vcore and power draw was too high for only a 100Mhz jump.

Request,

Change the Topic to "Post your AMD Vishera Overclock".

 

[Greenlepricon]

Got my 8320 up and running now. I haven't messed with it too much so it's just sitting at 3.8GHZ on a low voltage right now. When I have time I'll crank it up and see if I can make it sing

 

[jvroig]

Thanks for the OC specs and for identifying the sweet spot.

Question: Since all FX chips are unlocked, and if the sweet spot is a relatively moderate OC of ~4.5Ghz, would you agree that, in general, it means the 8320 is a better deal than the 8350 for overclockers?

I am making lots of assumptions here, most noteworthy of which is that ALL 8320 and 8350 chips easily hit 4.5Ghz, and also that ALL of them share the same sweet spot of ~4.5Ghz. Since I am not an FX owner, I have no point of reference, so I ask instead.

Have there been reports that 8320's OC much lower than 8350's?

I'm just trying to figure out here what the appeal of an 8350 would be over the 8320 for an overclocker. (The appeal is obvious for a non-overclocker - better overall performance out of the box). If an overclocker can push both chips to roughly the same level, I do not see the appeal of the 8350. Might as well get an 8320 and use the money saved towards buying a high-end CPU HSF.

Please do, and don't forget to share with us your settings and other relevant details of your quest to make it sing when you succeed.

Also, if you can identify the "sweet spot" as guskline did, that would be very interesting and helpful. Thanks in advance.

Yes, that is my impression as well. Looking at the TDP ratings, my estimation was that basically 8320 cpus are underclocked 8350 cpus, they just bin them to whatever supply/demand exists for the two price points.

But remember, unlike Intel processors for which you can buy that performance tuning plan warranty and OC/OV to your hearts content without undoing the warranty, with AMD processors you do invalidate your warranty the moment you OC.

So from that perspective too you can see why the higher stock speed bin exists. (for resellers who need two tiers of AMD octo-cores without involving warranty-busting OC'ing)

Hopefully u get reimbursed for that garbage.

I hope your parents do.
