I can get game stable 3.85, but it will crash after a few minutes of occt, the temps remain identical to my stable clock, but it restarts, I havent messed with NB clocks or voltages yet, but I may try it soon.

same with me let me be more specific maybe some one will help. I'm still a noob.

Ok I can get only to 3.7 stable using OCCT, intelburn, prime95 here are my OC specs

v core 1.4
cpu/nb 1.3
NB freq 2600

memory have not messed with it

My temps at 3.7 are around 37-38C idle and 48-50 load

Stock they are 32c and 41 load.

at 3.8 my temps are good I guess right around 58c load but it still crashes. Is it my memory? I really need some help.

So here are my questions.

1. Do I need to re-seat my mega shadow. I used the card spread method?

2. Do I need better memory I have 2GB of this Crucial Balistix and I'm running windows 7 64bit?

3. My bios is 1.3 there is not a bios update for windows 7 yet. Well I don't think. could it be that?

4. my case is in my sig a k62 and my house temp is 75 degrees. Is my ambient temp bad?

Thanks

The GD70 has 1.5 and GD70 Winki Edition has 2.0.

I would possibly update the bios to see if you can get any better o/c's on it.

Just make sure you follow the bios flash instructions very carefully!

Have to add one more to the list btw.

Info that was on the cpu

HDZ940XCJ4DGI
CACZC AC 0922EPMW
9289162F90234

I've managed to get 3.9ghz with 1h OCCT and passed (load temps were 53C)

I can get superpi 1m @ 4.0ghz occt dies after 10 mins (Load temps were 54C)

NB Runs at 2.4ghz for both all runs, but i've managed to get 2.720 ghz, any higher and it just won't boot.

System is as follows:
Phenom II X4 940BE
DFI Lanparty DK-790FXB-M2RSH
Corsair Dominator 2x2gb 8500C5D (running at 1066 although will post at 1180)
Powercolor 4890 1gb (890/990)
Corsair TX-750
Custom W/C Loop with XSPC 3.120mm Rad, Apogee GTZ, MCP-650, MCW60-4870, 1/2" Tubing and MCRES-2 (runs gigabyte coolant atm haven't had a chance to get Feser one Coolant just yet.)

Temps are probably your problem. Thats a nice cooler, and with the voltages your running 58c seems a little high to me. You might want to try and reseat it. I always use the spread method myself, just don't use too much...

On most boards I've used the PHII's seem to get a little squirely when temps get ~54c.

A couple things you can try:

1) Lower NBvid, you may not need 1.3v to achieve 2600. This should help temps.

2) Lower NB clocks and voltage to stock until you find max stable on the cores.

3) 1.4v on the cores seems a little low to get clocks above 3.7. If you can keep your temps under control (<54c under load), you should be able to slowly raise that voltage to settle things down. Anything up to 1.5v should be safe on air.

Hope this helps..... Dave

Sorry for my English again

Hi guys, I was wrote a letters to some of you for my probelm with overclocking. My CPU is overclock FULL STABLE оn 3,997MhZ 1,536~1,550 with stupid MB DFI DK 790FXM2RSH. But with my new MB Crosshair III i overclock only 3,940Mhz. Any other clock over 3,940Mhz fail with any other voltage

Here is what made with many nervous

**FlanK3r** · 09-27-2009, 01:42 AM

whau, nice chip!

**BiGSpender** · 10-02-2009, 05:15 PM

can some one help me with setting up the right timings on this ram on my msi 790fx-gd70

G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)

I am a super noob and need some help. Trying to get 3.8 stable. I no longer get bsod or random reboots after new memory, but I do fail prime 95 and occt after 45 min or so with a cpu error. my temps never get above 52c full load

**LS3_Airdale** · 10-02-2009, 11:42 PM

Hi guys, im new here, just showing my max stable overclock on stock vcore.

the temp 38C (after a hour goes at 41C, never more) on a 17C room, let me explain the past of my rig, i had a NZXT Apollo with stock fans and a Sunbeam Core Contact Freezer with stock fan i hit 49C in still a 17C room, then i tried with the Scythe splitstream fan on the sunbeam then it was 45C but it vibrates on the sunbeam but not with the stock fan, then i changed to a TRUE with the scythe splitstream fan, hit 43C no vibration, but i needed to remove the door fan because i couldn’t close it with the TRUE, so i changed the case with a Gigabyte iSolo, replace the stock fan with 2 Scythe S-Flex 1600rpm, now i hit 38-41C.

Primed95 "ed"

24/7 settings,the DDR2 RAM is at the (practical usage) limit,the cpu can still go higher to about 3600 with the
same voltage.

with winter maybe 4.4 GHz

**desnudopenguino** · 10-16-2009, 11:34 AM

Here's my highest OC so far. with 2x2GB of Mushkin 996601. I had to bump the memory voltage up to 1.85v to boot into windows. I'm running win7 32bit. And I did this on air... cold Rochester, air last night. Essentially all I did was reset the defaults in the BIOS, pumped up the cpu voltage & the ram voltage & set the cpu multiplier to x20.0.

Just got it today from Houston, set it to 20 x 200, played with the vcore a bit....very easy and smooth so far with my el cheapo AsRock board....this is what the 940's should have been from the start....

laterzzzzz..............

**I.nfraR.ed** · 10-23-2009, 02:50 AM

Here's mine 940, which is pretty old now, but i haven't posted at this forum

3993MHz The batch is 0852BPAW. Voltage - 1.575V, not 1.475 that cpu-z shows. I can't say it's very stable at that frequency, but not so bad chip at all.

**Dansh0** · 10-23-2009, 02:57 AM

I can confirm an unlock on 0922MPMW.

Mobo is a GA-MA785GM-US2H AM3/AM2+
memory is G.SKILL 4GB (2 x 2GB

The board was put in a Lian Li HTPC case I had sitting unused with a good power supply. Total cost of the build was under 330 bucks, which also included a 1TB 7200.12.
I had been leaning towards the propus until I stumbled across this thread and boy am I ever glad I did. It was a gamble not knowing if I was going to be able to unlock or not and I was kind of regretting not going for the "sure thing" until I got the board installed, did the hybrid setting change and posted successfully. I installed Windows XP onto a old raptor 74GB I had laying around and so far this thing is rock solid. The only other setting change I've made from AUTO in the bios is DTC to enable dual channel, which is still running at 800.

I feel like this is the best bang for the buck build I've ever done. I need to validate with stress testing tomorrow that everything is stable, but so far its up and running like a champ in XP, without any signs of instability. Kudos to AMD for leaving the heat sink layout unchanged for so long too. I had an old opteron heat pipe cooler that dropped right in place so I could avoid using that crap stock cooler. That's going to have to be replaced before any overclocking but I was happy I was able to use it.

My other rig right now is an E8650 OCd to 4.0 and this thing feels just as quick jumping around in windows. I can't know for sure which will be faster until I OC and benchmark, but for the 330 bucks this entire thing cost me it's a no brainer performance \ price wise. I can't be happier.
