Is that on water?

Is that on water?

Swiftech Apogee GT Block and custom water cooling

[Baulten]

Very nice. Wish I could afford water

Ive some sort of weird thing going on guys. Maybe it's a hardware failure of my motherboard but not sure yet.

I tried to OC my system in all sorts of ways and I had a lot of issues. I had hard times getting things stable, tried both other multipliers and HTT.

However, Ive always set Vdimm straight upto 2.16, since that's the max Vdimm to run its specs, so to be safe I just set it that way to rule out the RAM.

Now I set my Vdimm to 1.80 and only used multipliers to OC and got 3.8Ghz 2h OCCT stable.

Does this mean that PhII's dont like much higher than 1.8Vdimm's? There's however another eventual explanation;

This board and a 9950BE had at some point an issue because I accidentally inserted on DIMM incorrectly (one side wasnt 'locked'). Since then all 4 DIMMs (other then Ive now) gave a C1 error, or one wouldnt be read (all 4 inserted but only 3GB read) etc. I thought the IMC was damaged and RMA'd it. However, I just got a mail from the shop saying they couldnt find anything after a week of testing. This could mean two things, either I didnt check correctly and one/two DIMMs are indeed damaged or the motherboard has somewhere an issue

Before my move to WC I used another board where I couldnt get much more than 3.7Ghz stable, used high 2.16Vdimm back then. However 3.7Ghz was stable and it was on air. I couldnt get 3.7Ghz stable in above situations but now I lowered Vdimm Ive even 3.8Ghz stable. Hard thing to tell whether I couldnt get much more than 3.7Ghz on the previous board + air due to the Vdimm or just because it was on air and was almost hitting the 50's.

Did anyone experience any lower OCíng with 2.15-ish Vdimm? Or does this really sound like my motherboard is borked, although would the only ~3.7Ghz on air cause of the air? This is confusing, with a lot more testing I could most likely get it figured out, but I'd like to get some feedback running to prevent eventual useless time wasting on testing.

I have some trouble to... i think you are on something there, i have done 3.9ghz before in 3dmark but now i cant.... If i remember right i was on 1.95v before.(now 2.1v), i will try later for you.

Thx for info

[Rammsteiner]

And it isnt stable anymore after 3h of OCCT.

Man, Im starting to suspect this board/BIOS big time.

As soon as Gigabyte's 790FX-UD5P is available it's going to be mine.

arre you getting this bsod :the Irq_not_equal_or_less when is bsod's ?

I'm getting this too. I just stressed each core at 3.8ghz and they're all fine and the when I run them all I get bsod it's not heat related either temp was 53C.

Perhaps the thermal situation is different when all cores are loaded simultaneously.

[richierich]

Well in my overclocking adventure I've noticed that my system doesn't like increased voltage to the NB. I am overclocking my RAM quite a bit though, from stock 400MHz to 540MHz.

[demonkevy666]

no 53c is with all four cores loaded. 1 core load I only get 3-4C rise from 40C.

I get almost no BSOD's, the screen goes just black and the mouse and keyboard seem to lose power (Ive a G15, LCD goes off and the mouse speed indication LED is off as well). The feww times I got a BSOD on XP it was always a Machine Check Exception.

But mainly I seem to lose power or so, Ive almost no BSOD's. Im awaiting for the 790FX-UD5P. I checked the BIOS's of the AM3 ones to compare with the actual availability, think this board will be in 2~4 weeks. Whether Ive a batch or not, at least this board seem to pack a whole lot more than any of those retarded DFI boards did thus far. Combined with the pleasant results I got with the DQ6 a year ago, cant wait to get this.

I took a look at the BIOS manual, and it comes with loads of Voltage settings Scroll down to the BIOS page;

Hello from Barcelona i need help for to reach 3700 mhz in my 940BE
My PC:
MB Asus M4A79 ( Bios 903 )
Phenom 940BE
2x2GB Team Xtreem 1066 5,5,5,15
CPU Cooling : Water whit nice temps.
Vista Ultimate SP1 64 Bits.

I do not know how to do it because I do not see much with the oc amd, please can help with this, values that would have to put in the bios.

What are you stable at right now? I don't think your HT voltage should be that high. Try lowering it to 1.3.

[SilentOption_YG]

here my overclock speed for my Phenom II 940. I'm disappointed with the Coolit A.L.C. it only push me to 3.5ghz at default core voltage at 1.35.

I tried using 1.50v and 1.55v at 3.8 and 3.7but I end up getting a BSOD when I run the 3DMark or and Prime95. Plus the idle load at those speeds put me at 46 C and 59 C on 100%

Before i had it on a GA-MA790GP-ds4 and was stable at 3600 with 1.48, now it is impossible to achieve whit this asus.

Try vcore closer to 1.45v-1.47v

until then..

ya get an RMA on the FXB. we hope you get sent a good one, so you can enjoy your 940 instead of having to mess with it so much (like we were both doing on p1).

aside from that, how's the water treating you? getting accustomed to it?

[SilentOption_YG]

it work but my temp full load was uncomfortably high 59-61 C no bsod though. I need a better watercooling setup

[chew*]

Massman I took the time to do this is for you, best I can get out these $40 sticks of ram I know i'm a slacker.....I forgot to optimize.....

[richierich]

What OCZ Ram did you use Chew?

[chew*]

What OCZ Ram did you use Chew?

Golds? Almost dead so I crammed them with voltage, they won't do 5-5-5-15 anymore so I figured i'd find out how high they could go at rated timings and lots of voltage.

I can probably get a bandwidth shot of them if you want.

[richierich]

Are those golds stock 1066?

[cdawall]

i got another rev 1 phenom 945ES week 0825 like the last any guesses what my max clock will be

oh some gskill 2x2GB PC8000's to
