How to i OC my Ram?

[kensvin]

Can any one teach me how to OC my Ram?
Currently using Corsair pc1066 2048 5-5-5-15 X2 4096MB Dominator with Fan.

1st How can i OC my Ram? any software for ram clocking? (I tried in Bios, but it shown max already), My ram was 1066, is that board probblem?\
Teach me are simple yah thaks




Vista 64bit sp1
8.4CCC (< try to update to 8.5 but can't achieve (during update :Inf file not found, I think can remove previous version, any good driver cleaner tool for vista 64?)
Gigabyte 790FX bios ver F4

lets leave the graphics troubleshooting in the other thread.

as for your RAM

Can you give us a screen shot of CPU-z (if you dont have it: http://www.cpuid.com/download/cpuz_145.zip ), the main screen and the RAM screen.

unless someone here knows the BIOS layout of that board.. could you use a camera and give us some screenshots of the BIOS screens, most importantly the one(s) for overclocking.

Woo Tark is you again, I'm appreciate you always helpfull.
I thought don't want bother you this matter.
who know is you again, really thanks.
I bought WIFI USB Adapter, so i will upload detail to you tomorrow, now go back to hometown.

BTW where you from?

You'll need to use the ctrl+F1 combo to get the bios to show the additional OCing options. There you will find where you can adjust the timings.

[kensvin]

ic so what is your recommendation for my spec?

[JumpingJack]

Ok.... so there are two ways to OC your ram. However, let's make a quick point... percentage wise, RAM does not OC as much as CPUs ... RAM makers spec out the stock conditions much closer to the fail point for the RAM than the the CPU makers do....

A quick word on RAM.... I am not sure how knowledgable you so I will make a few basic points. As you already probably know, the 1066 RAM is actually clocked at 533 MHz, and is achieved through setting dividers in the memory controller. The voltage rating and latency settings are fixed by the factory in a special nonvolatile chip called the SPD. Now, not all BIOS recognize the advertised speed settings -- they only recognize the SPD specific spec values set by the JDEC. In fact, DDR2-1067 is not officially sanctioned by the JDEC (the memory standards board). It is often the case that users must manually set the ram settings even to achieve stock conditions.

Now, OCing your ram is actually quite easy to do... making stable is not.

You have four knobs basically for overclocking ram... clock speed (that is a given), timings, memdividers, and voltage. You have a locked CPU and the Phenom only has dividers to support up to DDR-1067 max, so your only clock knob is the system clock (sometimes referred to as the HTT clock or FSB clock). Nominal this is 200, your CPU IMC will divide this by 3:8 or multiply it up by 2.66 to get 533 Mhz (for 1067 ram). The only way to increase the RAM speed above 1067 would be to bump up the system clock from 200, start with small increments because this will also OC your CPU.

This makes it difficult for you becuase if you are unstable it could be your RAM or your CPU. When you hit a point of instability you have 3 items to try more or less... feed the CPU just a tad bit more voltage, feed the memory just a tad more voltage and/or lower your memory timings.

All of this is selectable in the BIOS, since you have a gigabyte board, use CNTL-F1 to reach the advanced options.

As with OCIng anything, know your limits first... your RAM can probably take 2.2 or 2.3 Volts safely, but I would not go any higher than that... your CPU can probably take up to 1.5-1.6 V, but I would again not go any higher than that. Also, move slowly, approach your best OC from beneath, don't ever shoot straight for the top.

Clear clear and very clear....some more question heh.

1st My CPU currently using factory Fan, It safe to reach 1.6v?, approximate how much C'?, normal my 9500 is 44c'.

2nd Is that my M700 psu afford to OC CPU GPU & RAM according my spec?

3rd what happen cause to shoot straight to the top? hang/break down or terrible damage?

thank you.

I can't answer #1, I dont know enough about phenoms and their voltages.
#2 - that should be ok, you wont be able to OC the CPU very far anyways.
#3 - dont shoot straight for the top - ever, if you go to high right off the mark, well, you can ask SF what it smells like
increasing slowly is always safe and is far far less likely to make your hardware go up in a cloud of smoke.

always doing the voltages last, increase the system clock and run tests like prime 95 multi-core until you are unstable, then increase the CPU voltage a bit and repeat until you are satisfied or you start noticing a substantial increase in voltage is required to be stable.
I would just set the RAM to 2.1V(or whatever they are rated for) from the get go.
it wont hurt it.

Isn't the stock voltage on those about 1.4V or 1.35V. You really don't want to go past 1.5V. Also more voltage isn't always going to be the answer to achieving a higher and stable OC. At some point you will max out the chip and no amount of voltage will let you go further. As a matter of fact you could easily damage the CPU with higher voltage. OCing should be a slow and careful prosses and voltage should be the last thing to be tweaked. If you reach a point where the OC is unstable then bump the voltage up by 0.02V to 0.05V. If that doesn't help then go up again but if you increase the voltage by 0.15V over the stock voltage you may damage the CPU. Not to mention the massive amount of added heat the CPU will be generating. If your clocking on the stock cooler don't exspect to get far before heat becomes a problem. You should have a much better cooler before you consider Ocing much past 500MHz over the stock clock.

how to know or monitor My pc stable or not, got any Software? to monitor of tester?

[MagicLess]

3DMarks should be good. With 20+ minutes run time that should assure stability to a degree.

This is my Bios OC setting, i totally no idea with this OC, don't know how to set... Can anyone teach me?

[JumpingJack]

Ok, shot by shot...

First shot... the HTR voltage control involves the hypertransport reciever, the HT has two point to point links, each 'agent' on the link has a transmitter and a reciever such that the links together can communicated bidirectionally between the agents. This setting has nothing to do with memory overclocking.

Second shot.. memory controller frequency, this is a bit of a misnomer by Gigaybyte. This is the not frequency that it will control your ram, but the north bridge frequency. The multplier is the option, so setting a multiplier of 9 will run the northbridge at 1800 MHz, this also is timing the L3 cache, so you can help an overclock by increasing this number -- but too high will become unstable.

Third shot -- the PCIe clock has nothing to do with either CPU or memory, it is the clock that times your PCIe link used by most commonly the graphics card, this is a 'touchy' clock in that it is easy to destablize your system, leave this alone.

Fourth shot, the HTT voltage is the common voltage for the hypertransport link. If an overclock on your CPU becomes unstable (by using the system clock, i.e. raising it from 200 to 210 or 215 Mhz) sometimes increasing this voltage can help stablize the system. Do not go much more than 1 or 2 notches above normal, it can damage the CPU.

Fifth shot. Chipset voltage is not worth monkeying around with just yet, but notice the CPU frequency option just above the box, currently 200 Mhz, this is the option you want to slowly increase to over clcok, try 205 Mhz, boot and test, then 210, boot and test. This is the OC knob on your CPU.

Sixth shot. This is the memory timing page, set this to auto for now, if you are unstable at a particular overclock, you can loosen the timings (i.e. make the numbers larger) -- the top 4 numbers, leave everything else alone.

7th Shot. DCT mode ... set this to ganged. You will get better memory performance that way... Unganged is a special feature of the memory controller that is going to be utilized when AMD sandwiches two die together to increase core count. AMD is going to embrace the 'cheesburger' approach that Intel currently uses... for now, unganged has no practical benefit.

8th shot - see memory controller stuff above.

9th shot -HT link width... leave at auto, default is 16 bit.

10th shot -- this is the HT frequency, as you increase that 200 Mhz number for the CPU above... setting this at something below 1800 helps if stability is a problem.

Very clear , but i'll try and raise my after tried. thanks

[zig2man]

Hi there...my pc was working ok untill it said that I have to check a signal cable or no signal..

[Tark]

hey zig, welcome to XCPU's, Could you please start your own thread? Include details about your PC as much as you can tell us so we can start helping you

thanks
