How fast can you get an FX-8350?

[rtpb5642]

My rig:

CPU: 8350 @5.2Ghz
GPU: XFX HD5450
Motherboard: Sabertooth R2.0 990FX
PSU: Corsair RM 850w
Storage: 1 120GB SSD and 2 WD Black 1TB in RAID 0
Cooling: Corsair H100
RAM: 8GB 2x4gb GIEL @2133

So i have everything running well at 5.2ghz, i can get it to 5.3 but not stable, like it boots but can't do anything stressful. At 5.2 my CPU is at 1.62(or 1.61 I'm out so can't see now) so running well at 5.2, and id like to get it faster
This is not a gaming rig, just something i build to overlock the *** out of, how fast have you gotten an 8350? if so what specs like voltage etc. i want to go to Ghz.. lol I'm building a temporary cooling system that will run on live tap water just to see if i can get to 6Ghz... so far the H100 is holding up. At 5.2Ghz idle is 34C and i don't put much load on it other than prime 95 that got it to 60C so i stopped it, intel burn test works well until 5.2

Thanks

temp's are my issue. I can get 5.5 at 1.675(was really bored and had $200 set aside just in case) but that made it all of 2 minutes into prime before I was hitting my temp ceiling haha.

Ok thanks, did u change NB at all?

 

[RyanCouch]

I had to bump it up a little bit if I remember correctly, but this was when I first got it. so I can't remember. I certainly don't recommend it unless you want to buy a new cpu haha.

Others have now gone faster but they make no real claims to stability. I think "johan45" has cpu validated his 8350 or 9370 at 5997Mhz in one of his posts in the "putzen" thread.

Done in Jan of 2013 some later stuff added not sure when I last posted in that thread.

Testing does FX-83xx seem to flat line after 4.3GHz

I was prime stable @5.5, 2 hours with a lot more cooling than you, 5.0 is a very good clock with an h100i.
go dig very deeply into the just putzen around thread, that should take no more than a few months to dig through, and Rgones link will make great reading.

 

[Johan45]

As Rgone says I've had the 9370 to 6.0 but and this is a big one you really need exceptional cooling and I had water at the time that was in the -20c range.. Like C_D says for the cooler you're using if you want good stability 5.0 is a good mark depending on the voltage needed to run that clock stable. What are you using to test stability and temps??

 

[ShrimpBrime]

5.2ghz is a good number for these chips. Mine was pretty darn stable at 5.2ghz, nice cool temps. Not -20c like Johan's, but cool enough to get'er over 5ghz!

Good show OP!

 

[caddi daddi]

shrimps, that's my kind of vcore!!!!

 

[RyanCouch]

that's what I was saying haha, I'm pretty sure I damaged my chip by pumping the 1.67 that I put through it. but those temps are like...I need cooling haha

 

[caddi daddi]

also, a little over 1.6v a lot of these fx can get a little unstable.

 

[RyanCouch]

I was stable for like....30 seconds...maybe haha

 

[caddi daddi]

you gotta find one that will do 5.0 at around 1.5 and then cool the crudd out of it.

 

[RyanCouch]

I need to find out what mine takes to do 1.5

This is as far as I can go with my cooler. I've gone out to 5.4 at 1.600 volts but needed cold weather to get there.

I want to add another rad to my setup but I may not now that I have a DICE pot.

Man you guys are ballsy with that vcore haha.

 

[ShrimpBrime]

It's funny you say that but.....

Running a Prime95 on a 90nm Windsor as we speak at only 3.423Mhz and is using 1.5250 + 3% LLC to get there.

Now that same voltage nets 5ghz ++ on 32nm FX. It's kind of neat to watch it all go down, talking 1600mhz clock increase between the two chips.

The last time I went ballsy was pushing 2v at 7ghz

 

[Priller]

Man you guys are ballsy with that vcore haha.

I would have gone further but ran out of thermal head room with a single 360 rad and needed very low ambient temps for 1.600 volts. I can do 1.5-1.520 volts but anything higher and it throttles hard.

I don't think you can damage these chips at ~1.6V. More likely it will be damaged because of too long work at too high temps. I actually checked that when you turn off every protection and power saving feature then FX can run at ~99*C and they're shutting down above 105*C.
Depends from cooling, when you see them in idle ~0*C then internal temp under load can still jump to 80*C+ but software not always registers it due to too long delay between read points. Then it randomly crashes.
My FX8120 was overheating above ~1.55V on SS ( -20*C idle ) and I simply couldn't set higher voltage for any longer test even though 1.55V was enough for ~5.5GHz. Valid was max 6.08GHz ~1.62V or something near ( long time ago ). FX8320 was much worse. My A8 6600K hates anything above 1.7V on SS so I guess I need LN2 as dice won't help much. One board already died when I was trying 1.8V+.

Overheating point can be lower than declared max temp. For instance it can be also ~30-40*C when you run at already high clock and high voltage. Also remember that temperature reading points are not showing all CPU temp and core temps are always lower than some other parts of CPU. When you are using sub 0 cooling then you are freezing all socket. When you use air or water then you are only cooling IHS so parts that are touching directly IHS.

Actually one funny thing is that good watercooling set is as good if not better than ss for these chips. They're simply overloading most ss units. You can see nice temps in idle but under load it spikes to the values your CPU is losing stability.

How about 5.3 and stable at 1.5V?

I've long suspected that I lucked out on a nice chip and seeing the vitamin V everyone is using to get past 5.0 confirms it I think. Still having trouble with stability past 5.3 though although I've got rock-solid configs for 5.25. Any suggestions? It's -30 here in Manitoba and I wanna use it!
