Exactly. even at stock speeds, my 1055t doesnt bottleneck my single 6850. although it does when i have two 6850s. thats what OCing is for. anyways,why do you have an nVidia card on an AMD mobo?

It's a BE processor, the only thing the op needs to be mucking about with is the CPU multi and the CPU voltage.

AMD Phenom II X6 1100T Black Edition

When using that ram plays no part in the process of overclocking, unless you want it to.


If it's the 1055T or the 1075T then you overclock at the HTT/CPU Clock level, for that you can't just up the HTT/CPU-Clock without adding to the NB voltage hence the instabilities.

OP you need to do it like this:

Use the HTT/CPU-Clock to up the CPU MHz/GHz since you are locked at a 14x multiplier.

To do this you need to apply extra voltage to the CPU but now you also have to take into consideration the NB voltage also.

Whilst doing this you need to keep RAM,HT and the CPU-NB at stock due to them also being linked to the CPU Clock/HTT/FSB, So the FSB goes up the RAM/HT/CPU-NB multipliers come down to keep them at stock whilst trying to stabilize the CPU.

The OP's problems sound similar to when I unlock my 4th core and the CPU won't overclock an inch no matter what I do. I'd just take all the voltages up a few notches, try a high FSB-normal multiplier vs low fsb-high multiplier and see if anything sticks. It is possible that he just has a CPU that doesn't want to OC?

hmm mybads, turns out i have a 1055T instead, mustve put the wrong model number into my sig D:

sorry if this caused any confusion

@smashmouth, Thanks for the info

hmm patawic, have you checked that your voltages are set to auto?

rep +1

This is precisely how to go about it.

Decrease ram multiplier, NB frequency and HT. Then increase the cpu clock.

I like to keep my system at stock voltage for longevity sake. You should be able to get a decent OC out of that chip, even at stock voltage, as long as you keep your other system components at stock.

its wierd, as soon as a hit a frequency of 250mhz it stops booting, but even when its set to a low 230mhz it boots, but refuses to go above 2.8ghz, it just automatically changes the multiplier to x12 so it stays at 2.8ghz, i have no idea why D:

UPDATE: turns out AMD overdrive is retarded, CPU-Z is showing slightly more accurate results with a clock speed of approx 3.4ghz

UPDATE2: it appears to be running fine with a frequency of 240mhz, dont know what it is about the 250mhz mark that makes it stop posting D:

UPDATE3: i started bluescreening at 245mhz, is that indicating that i am lacking voltage or what?

patawic, do you have the newest BIOS on that mobo? My cpu chucked a ***** fit any time I changed RAM dividers until I changed the BIOS.

But might I add it wasn't a strait forward FLASH.

I flash in increments, the first one I flashed to caused my comp to keep rebooting, I had to yank the 3v cell and short the board to reset the CMOS.

Then I could get in to the bios to take down that horrid graphic on boot. I took me 8 times of resetting the CMOS before I go the latest BIOS on.

So just to let you know, it might happen to you also since you're running a GIGABYTE boards also. But I may be wrong also.

Bluescreen, I put down to ram and timings. Another thing I had found to be of interest is that if there isn't enough voltage to the NB which controls the CPU REF/FSB clock it will not be able to communicate to the HDD's.

its a pain, as i never actually get to see the first POST screen as my monitor takes a couple of seconds to display an image, and by that time it is already detecting my hard drives :/

CPU-Z will tell you the version of your bios in the motherboard tab.

When you increase your FSB, make sure you are dropping your HT Link and NB multipliers. HT Link keep as close to 2000mhz as possible, the NB you can run a little higher if you want to. As you go higher, you may need to add more CPU voltage and/or CPU-NB voltage.
