Phenom 2 940

[colflo101]

i dont think so when i set mine to default it 1.38 so i dont think so

mine is set at 1.42 v on default for some reason i just dont trust setting the voltage to high mine is overclocked to 3.30ghz at 1.38v
i might just leave it at that or i might increase it a bit more its ok as it is the moment amd are bringing new phenoms out stocked at 3.50ghz

The MoBo makers BIOS is going to dictate what the default voltage is set at. According to AMD's web site voltage can be anywhere from 0.8v to 1.5v to stay within spec. My default voltage is 1.34v But I'm currently running 1.475v @3830.
I've seen a lot of posts with people getting to @3.6 at default voltages. For clocks higher than that it's going to take an increase of the Vcore volts and a raise in memory volts a well. 1.8v is the default in most all boards and if you look at the specs on almost all DDR2 memory the JDEC or EPP setting is going to be 1.9v to 2.1v
So to push the PII's to higher OCs you'll need to see what the voltage needs to be set at for you memory. If your only getting @3.3 to @3.4 chances are your memory is set below spec.

so you think my memory volts could be to low when i look in everest it states this for my memoryModule Voltage SSTL 1.8
is that the memory volts do you think and do youthink it should be higher than that thank you for your advice

 

[unclefester]

The SSTL 1.8v your seeing in Everest is the industry standard number and will not change. The only program I have that will show what the memory voltage is running at is AMD OverDrive. If it is set to auto in the BIOS you won't be able to see it there either.

I found your memory at NewEgg and it is rated 1.8v with EVP (extra volt protection) of 1.9v So you may have a little headroom to play with. But you may have to go to OCZ's site to make sure you void the warranty by upping any voltages.

i installed AMD overdrive but it wouldnt work iit just says not recognising something cant remember what it was would that be a better and safer way of overclocking the cpu i cant figure out when you suppose to know when to increase things when overclock i just thought as soon as you increse the multiplier and it goes to blue screen you must increase the cpu voltage so when do i know it might be the ram volt .what would you say is a safe voltage increase for the phenom i just dont trust raising it to high becouse of cpu temps i had the volts at 1.45 before with 28c idle and 44c full load with multiplier at x17.5

i appreciate your time and advice thank you

 

[unclefester]

Can I get you to run a quick bench test in Everest and let me know what your memory timings are?

OK, I went to OCZ's site and you can run your memory to 1.9v without damaging it or voiding the warranty. Setting the Vcore to 1.45v shouldn't be a problem either. With those ajustments you should be able to up the multiplier to 18 or maybe even 18.5 with a little luck.

Be sure and keep an eye on the temps.

i just copyed these from everest
Memory Timings
@ 400 MHz 6-6-6-18 (CL-RCD-RP-RAS) / 24-45-3-6-3-3 (RC-RFC-RRD-WR-WTR-RTP)
@ 333 MHz 5-5-5-15 (CL-RCD-RP-RAS) / 20-38-3-5-3-3 (RC-RFC-RRD-WR-WTR-RTP)
@ 266 MHz 4-4-4-12 (CL-RCD-RP-RAS) / 16-30-2-4-2-2 (RC-RFC-RRD-WR-WTR-RTP)

i dont know if this is whAT YOU NEED if not let me know what info you need please i dont if you mean run some sort of test or not
but this is what it says about the timimgs on the memory page thank you for your help

 

[unclefester]

Those are the JDEC reference settings. Here I will show you what I'm talking about:

This is the Latency test in the Everest Bench section, my timings 4-5-5-15 CR2 (this is what the numbers represent CL-RCD-RP-RAS)

the version iam using is 5.00.1650 it doesnt seem to have anything looking like your test on this one unless am not looking properly is they any other way of showing you it thanx

i found this as well ( ganged dual channel ddr2-800 sdram (6-6-6-18 CR2 @ 400 MHz (CL-RCD-RP-RAS) /
hope this helps thank you

Let's try this an easier way. Open Everest and in the top left-hand corner click on to Tools. In the drop down menu you will see Cache And Memory Benchmark, click on it. At the bottom click Start Benchmark.
This is what it will look like.

 

[wildgene789]

did you just increse the multiplier and voltage to get that overclock and leave all other settings at stock

yea everything else at stock but u need a good cooler soo u been warned

ok is this it

From what I'm seeing your memory is definitely going to hold you back. With timings that loose and not being able to up the voltage, it will cut down your options.
I also noticed you drop your clock speed to @ 3300 ?

these are some images of my bios pages i took them from a web page i found they are the same as mine could i make any decent
changes with this bois <center>

these bios setting are the same as mine but the cpu and memory is diffrent ok

 

[unclefester]

Meh... about the only thing I can say to do, is raise the Vcore somewhere close to @1.40 Keep a close eye on temps and try different combinations with miltiplier/FSB until you find a decent combination. Then see if you can bring down the numbers on your memory timings.

i had another go last night raised the multiplier to x18 and the cpu voltage to 1.45 v it still got blue screen i also raised memory volts to 2.1 i got a feeling the power supply could be the problem as well its a 850watt but is was a very cheap one it cost about £30 so you can imagine how crap it is i got cpu volts now set on 1.38v and multiplier set to x16.5 and its ok at that but when i raise the multiplier any more it seems i have to raise the cpu volts to much . and on my bios i have cpu voltage and vcore voltage whats the diffrence in them i know one reads higher than the other

thank you for your time and advice
