Well, I've got a 8150 up and running. However, this Biostar 990FXE board is not playing nice with overclocking. It has an unusual dual method for clocking, including a pstates option, which changes default clocks for multiplier and NB, along with voltages. Thing is, it gets fruity when you set defaults over 20x, and then is really touchy when adding BCLK. However, it does clock memory well, taking my Geil EVO II 1866 8GB kit to well over 2000. I think I need to grab another board to play with. Suggestions under $150?
GIGABYTE 990FX-UD3 might be $150 or less.

P.S. Have they corrected the issue with some older games like Valve Titles and Deus Ex BSOD when using the updated BIOS with a Bulldozer?

My buddy just got that board but he's running a 1090T on it though. However, for 4GHz, it does it effortlessly.

As far as your question, what about this Gigabyte? Has good reviews on the egg, seems like a popular choice. Looks great too!

I've got that board, it's the worst board I've used in years. (990fxa ud3)

Bios is useless, latest bios causes massive v-droop issues and even if you set the voltage higher to compensate you'll still require more volts just to get things stable ( but you need the latest bios for APM features)

Also their support is awful.


*edit*

New beta f6f fixes v-droop issues but only if the voltage is set to normal.

If you increase voltage v-droop is enormous still.

Setting + 100mv results in stock voltages give or take.

Just took a look at that board on Newegg, looks really good! Not badly priced either I would say.

Well going by specs all the boards In in my price range ( £130 max) were similar so it came down to layout and aesthetics ( since none had bulldozer reviews yet I didn't know how they would do with it, all had similar x6 over-clocking capabilities)

And with an all black/grey design and good layout for crossfire the ud3 won out.

Unfortunately when it came to bulldozer support well, gigabyte didn't do so well :laugh:

A shame really because the ud5 and 7 get frequent updates.


Damn it's nice clean layout swaying my buying decisions

New potential 24/7 overclock.

Let me know if you guys think it's safe ( not used to pushing far with voltage)

4.6 ghz @ 1.42v

General usage temps don't go over 50c ( HWMonitor)

Intel-burn in test temps don't go over 60c (default settings until it passes also HW monitor )

I'm running 4.7Ghz with ~1.425v load "crunching" 24/7.

On my Intel rig I'm running 4.7Ghz with ~1.31/1.32v load "crunching" 24/7. I usually prefer to run with lower vcore for daily o.c.'s but I decided to go with 1.4v(+) so I could scale MHz as much as possible to make up for BD's lackluster ipc performance.

Woohoo....water went in today....have never played with any the features on the M/B and CPU so I started off light.

Turbo got me up to 4GHz and all I had to do was make myself a coffee, good times.
Temps on Intel burn didn't go over 36c...
Going to tidy up my living room (parts everywhere for looking out my cooling gear) then spend the next 3-4 hours trying to break 5GHz...I have a water chiller that needs some TLC for the coming months but right now:
Me.
Some water.
Some fun.

EDIT: 30 min later 4.6GHz

Hmm well, 5GHz....
used alot of volts to push it through right enough...just spend a few hours polishing and run it @4.5GHz for the rest of its days.

IF I find bench stable I dont mind running benches with 5GHz at those volts but only a madman would run that 24/7...Still finding my way round this board and AMD overclocking last OC I had with results was a Q6600 @ 4.25GHz on a P5K so much simpler than all the options I have now.

5ghz.jpg


Intel burn was giving me max 63c....forgot to SS, ach well, no doubt I will post again tonight.

EDIT:

Ach, found 5GHz under 1.5v but cant find 5.5Ghz yet...getting it to boot but just no where near stable.

Would love to try my chip underwater, seems like it could be a goodun :D

I'm going to try 4.7 with air now lol


*edit*

I failed : [

Nothing can make it work, cept extra voltage and well, then I go past 62 degrees and that just isn't fun.

Going round in circles here....what is happening with the temp readings.... only clock I have on it right now is 10MHz above base so its running 3.26GHz

IDLE
temp.jpg


LOAD
temp.jpg


BIOS is reading the same as ASUS system info, cant be right can it?

AMBIENT TEMP 21c

For cooling I'm using:

Black ice GT 360 rad

MCP655 Laing D5 Vario pump

OCZ Hydro block

The fans on the rad are generic, lost my loons in a house move. Would that cause my temps.

I have re-seated, and I'm using MX-2 tim.

Last processor I had under this water was a Q6600, @ 1.46Vcore 3.8GHz and I still have screens of the temps hitting 45@ load (with loons though)

Is this processor that hot?
Is the generic fans ruining a good loop?
Do I need a new waterblock?

that's nothing for temps @ that frequency. I dont wanna say but yes these fuckers run hot and draw alot of power for what they do. my 8150 was yanking 799W from the wall and water cooling was not working very well under extreme cpu burnin... 82c :cool:

Repost the correct picture and I'll try to help :p


Idle temps on these chips always seems to be way off by the way, currently reckons I'm running at 13c but under-load I go to 60c so load temps are generally correct. ( or seem to be anyway)

Load temps are more correct then idle. Wanna see how your cooling is up to the task? Run linX max mem and you'll see how hot these chips run.
