overclocking the phenom II 940

Super XP · Feb 8, 2009

How the hell did you get the Phenom II 940 @ 4387 MHz stable with only 1.375v ? And that NB speed is a killer lol

1Kurgan1 · Feb 8, 2009

I have a feeling that it isn't stable, with Overdrive its really easy to see a high clock real quick.

Chicken Patty · Feb 8, 2009

I want to know what board he is using. Thast a good clock on the FSB!

dumo:

what board are you using.....? Cooling - Liquid Nitrogen?? - that cant be right....

dumo · Feb 8, 2009

@ Super XP... Vcore actually is 1.68V with single stage cooling

@ Vulkan... Mobo is Asus M4A79 Del. with Crucial Tracer 2X1GB ver. 1.1

Heres some 3ds..

GPU softmoded on GTX 295 increase GPUV from 1.04V idle to 1.24V idle and load...

Phenom II chips have ACC built into the processor so you don't need ACC on the board in order to use it. Also it will not work if you try to enable it in the bios because of that.

Can anyone confirm this? ACC is the only feature that makes me choose the Asus M3A79-T Deluxe above the Asus M3N-HT Deluxe/HDMI for my upcoming Phenom II build. I don't have a preference for SLI or Crossfire, because I can get both ATi and nvidia cards cheap.

Yes it's confirmed. Do not enable ACC with Phenom II's or your systme will crash or do funny unstable things. Phenom II's already have it built in. One of the TECH guys at the ASUS help forums confirmed this to me.

Thank you for your reply. Do you also know if ACC will work fine on nvidia chipsets as well?

I think so, but not 100% sure.
All I know is the first Phenom's did not have ACC built into them, this is why it was on the mobo's South Bridge. But the new Phenom II's have it built in. It may be so but I've seen some nice Phenom II OC's with Nvidia based motherboards.

and to answer your question, never bothered believe or do not believe. It's up to you.

and they say MSI cannot overclock.Also to be fair this is a 945

dumo · Feb 9, 2009

Thanks Spearman

AM3 chip should be more in term of oc scaling based on this Asus AM3 board performance.

Added up orb links on 3Ds post.

Super XP · Feb 9, 2009

Nice OC, what cooling are you using? My problem is everytime I go to 4GHz my temps go right up and the system crashes.

Hi all...

Not much in the sphere of OCing, but simply question, does that Phenom II 940BE will run on me GB MA78G-DS3H...bought it not too long ago for HTPC and would like to strenghten its capability...plz... :cry:

p.s.
according to the GB site F6 BIOS allow this CPU to be nested in there, but, seriously would power block have enough juice for these...

Thats nice X4 945 ES :toast:

Crank up HT and NB freq, ddr3 platform will make it easy to play at >300 HT and >3000 NB.

With DDR2 and X4 940 kinda hard to reach that, eventough AM3 mobo have all the capabilities needed to run ddr3

Heres with Asus M4A79 Deluxe AM2/AM3 and Win7 in ddr3 teritory...

NICE OC Dumo :respect:

I have both the OCZ Vendetta I & II. The one fits just fine but the II does not fit good. It blocks one of my primary (Yellow) DIMM slot. I just wish there was an attachment for AMD mobo's so that we can install heatsink/fans like Intel mobo's which do not block any memory DIMM slots because it sits horizontally where as the AMD sits vertically.

How about this SUPER FAN lol

The heatsink I have allows you to mount the fan in push pull formation front to back wiithout blocking the ram slots on AMD boards, as long as they don't have reaper heatpipe heatsinks the first one fits under it. Also once installed it you don't have to remove your motherboard to install a new chip. Unlike my old TRUE that only let you install the heatsink facing up and down on a AM2 system

Hey Trt740,
I was thinking of getting that fan but you mentioned something about the reaper heat pipe. I have all the slots filled with ocz reaper 1066 (8gb), so my understanding is that i would have to leave the first slot empty? I have a biostar ta790gx mobo by the way.
Thanks

I too have 8GB of DDR2-1066 OCZ Reaper in all my 4 slots.

can someone please answer this for me, the PII 940 BE with the Asus M3A79-T..... should CPU PREFETCHING be on or off?

no with regular ram, that doesn't have the large fins or heatpipe they fit under that heatsink.

CPU Pre-Fetching should be enabled with all Phenom based CPU's for better performance.
