Freak Occurance NEED HELP!!

[AMDxx165xxfx60]

ok, got this opty 165 on a DFI ultra-D lan party mobo that won't go above 2.2 ghz .
Weird thing is I can push my FSB high around 240s , but the multiplier is stuck on x9 even when i use a memory divider. I have it set on the 5/06 divider but instead of the x11 multi i'm getting x9 results. What's even stranger is that everything shows up on CPU-Z as it should only thing is my clock speed shows up as if it's x9. The memory divider even shows up as x11 in the memory section. Any ideas?

the 165 isa 9x200Mhz design it can only go up to 9x multiplier.

A memory divider is not a multiplier

You should read the forums, and search for a64 overclocking by Zebo i think his name is.

You can also look at my sig to get an idea maybe...

for example my set up
HT set to 3x
FSB/HTT set to 289
multiplier set to 9
VCore set to 1.475V

Memory, it depends on what kind you got i have DDR500 so normal range is 250Mhz
So i set my divider to 183MHz, so it is the FSB/HTT(289) * (183/200) = which is 263Mhz.

So if you use DDR400 and say you used my HTT setting (289)
you would want a divider around 133-150MHz. So if it was (133/200) * 289= 192.

Hope this helps some

Opty 165's are 9x, you can't get 11x out of them, only 9x or lower. That said 2.2G is a bad OC for the 165, 2.6 G and higher is almost always quaranteed if you know what you are doing!!

what i'm saying is that, in effect, it creates an 11x mutliplier, after you're done doing the math . .... and i do know what im' doing, i have my rig set up to 2.8ghz right now , mumbo jumbo aside , what would cause cpu-z to read the divider correctly , but still allow only an overclock of 2.2 when it should be 2.6 229FSB on a 5/6(166 mhz) dram frequency divider

237 FSB *

how is it letting you do 237x11, if the Apty 165 ONLY goes to x9!!?? if you set it to 11, it will just run on that x9 multi... follow Zebo's instructions plz

237x9= 2133mhz :roll::laugh: sorry bud, you do NOT have an x11 multiplier on your Opty 165

read Zebo's guide...you are confused


question:why only ~240x9?

answer: RAM

People more knowledgeable on this subject than you are telling you that you are flat out wrong. For one thing, and the most important part of this is that the Opteron 165 is locked so that it can go no higher than 9x though you can go lower. That means that without some serious insider knowledge and know how to physically modify the Opteron 165 (if even possible), you can't go higher than a 9x LDT multiplier on an Opteron 165. The LDT multiplier being the equivalent of the older FSB multiplier though it also controls the speed of the hypertransport bus. So in case you missed that, you can't go higher than a 9x multiplier on an Opteron 165 no matter what you do.

this man speaks the truth!! we only tell you this because we want to see sick clocks out of that chip :beer:

sorry for the mix up i'll let you know what it pulls tommorow . thanks for the clarification

clapclapclap

best of luck man, please keep us updated

Good luck with the OCing




And as for how to calculate RAM dividers:

(CPU multi x 200) / RAM divider (i.e. 166) = ___(always round this up if not whole number)

CPU multi x HTT / result of initial calculation = actual RAM speed

e.g.
OCed CPU clockspeed / result of the first calculation = actual RAM speed

one full example:

12 x 200 / 166.66 = 14.4 rounded up -> 15

12 x 220 / 15 = 176 aka DDR352

Make sure your hypertransport speed does not go over about 1100mhz, most boards get wonky when you go past that though boards have been known to hit 1400mhz without a problem. There is no noticeable performance gain going that high, nor performance loss by going a bit below 800mhz. So I'd keep it lower, between the 800mhz to 1100mhz range for maximum stability.
