AMD FX OC'ers Club

[dumo]

Hey Dumo, I'm getting BSOD's at stock. Are there any bios settings that need to be on or off that you can think of? Everything in my system is tested and stable, this is definitely CPU or bios related.

*Bah, this CPU is junk. It's going back for a replacement.

What ram and bios you use Erocker?
Bios 9911 has special settings for PSC based ram.

Heres with SS that barely keep up with load and BBSE Gskill rams

For some reason I can't boot up to windows with 5Ghz from bios...have to use AI suite II in windows for multiplier up

I'm surprised that more TPUer's arent running FX cpus? I was hoping to get some temps and voltages for 5ghz on air and water. I might just jump on the FX (8120 though) wagon and give it a go myself. My SB setup is fast and does everything I want, but its boring to overclock and bulldozer seems fun to play with.

If I still had a job I'd of been posting bench mark results and cool stuff here.

Hell even though I've got no income I'm still tempted by it.

I'm a very heavy multi tasker so the extra cores should come in handy for me.

With the 0813 bios. This isn't RAM related, I've tried Elpida Hypers (Dominator GT's), Mushkin Ridgeback's, G.Skill Snipers, Corsair Vengence. Three different O/S installs, stock or overclocked, I get random BSOD's and when gaming, things just freeze up and my GPU drivers crash. Video card is fine, all of the other hardware works when the FX CPU isn't used.

@Johnny5

I know I am looking into an FX8120 myself.

It's not a performance issue in that respect.

This should have it's own thread. Quite interesting indead. In regards to the bios, ASUS and Gigabye will have to issue updates to fix any related issues. Erocker, this may also be an issue with your unstable PC, you never know. I would contact ASUS directly and even get another board if you may. Or just get your AMF FX replaced via Warrenty.

 

[xkche]

I just say, maybe "other bug" (another more) cause RAM problems...

 

[pantherx12]

Someones agreed to buy my 1055, I'll be joining to guys soon

 

[Volkszorn88]

I'm not sure if I should just make the jump in purchasing the 8150. I already have a 990FX board. Or should I just keep my 1090t?

From what I can tell, BD excells when it comes to complete CPU stress over the i7.

I only game, I don't do any video editing/coding...etc So any honest opinions?

Keep the 1090t. I stand by this advice 100%.

So has anyone been able to find evidence of 5GHz stable on air or water with a FX 8xxx? I haven't. Despite FX 8xxx being sold out everywhere, no one has them running at 5GHz stable. I've checked every major overclocking forum, and on one has these running at 4.8+GHz STABLE on water or air. Now if I reflect back to the 2500K and 2600K release, when those were sold out, there were tons of threads with prime95/linx/whatever 4.8-5.3ghz stable on both air and water. Was the launch supply really that sparse, or are these FX chips simply not clocking like people expected?

I know erocker is having issues and dumo is having BIOS settings issues, but no one else on here has one and has some results to share or any kind? I'm interested in getting a 81xx but if no one is showing me some screenies with temps and oc stability I may just stick with my boring 2500k and wait for Ivy. Come on TPU!

How many did NewEgg have in stock 3 of each? lol

My 5ghz run was stable. Look back a couple pages. Here: http://www.techpowerup.com/forums/showpost.php?p=2424770&postcount=52 I found out what is causing instability with my system... wait for it.. AMD drivers! The built in AMD overdrive in the latest Catalyst drivers are screwing with my CPU. I'm running just the drivers right now and am having no issues. Amazing. :shadedshu

 

[johnnyfiive]

Ah, sweet erocker. So three runs of IBT, did you try prime95 blend at all?

 

[Chicken Patty]

I've just been reading through this and I think BD has got some good potential but it just needs to mature more.

 

[erocker]

Ah, sweet erocker. So three runs of IBT, did you try prime95 blend at all?

No, but I did do 30 runs of IBT with high ram setting. I'm using a triple radiator for my cooling and at 5ghz with the voltage it needs it's on the safe side, but just. It reallly sucks the electricity too.

 

[bucketface]

@erocker
What is the lowest stable voltage you can get at 4 to 4.5ghz, is 1.3v or lower possible at or near those clocks?

@erocker

I'm currently running at 4ghz 1.28v

Nice, 30 runs of IBT definitely heats CPUs up, much more than P95 or even LinX. So what is the 'safe' voltage and CPU temps for water? Also, how many watts was it pulling at 5GHz? 500+?

506 watts under load with IBT normal setting.

Sorry, I missed which model graphics card you're using. Regardless, that seems like high wattage.

 

[erocker]

Single HD 6950. At idle it uses .9v ~ 28 watts.

I think it's 2 x XFX HD 6950 CrossFire (unlocked), but I can be wrong.

I stand corrected

1gb card too.. Don't know if that makes a real difference though I doubt it.

Okay.. so it's been a few hours and no more warnings or errors in the event log, I'm finally downloading some games. Dirt 3, MLB 2k11, NBA 2k11 and Street Fighter 4 so far. I'll get some Fraps running with those. Hopefully AODDriver problems won't occur. I'm just going to be running at 4ghz due to the cooler I'm using and this way people can compare it to their Phenom II's at around that speed.
