phenom 9500 won't overclock - Page 2

post #11 of 27
Mmm I think that before raising the FSB a bit.. i'll buy a new cooler, because according to EVEREST my CPU temp is 59º
Perhaps a Typhoon ...

And.. one question: HT multi one stop down is.... (normal value and new value?) and the same for RAM Speed (i have PC6400)

you always want to keep your HTT link below 1000mhz

That's not true. I've seen motherboards, mine for instance, able to run HTT at close to 1200MHz if you're lucky. It's good to keep it below, but speed is speed

Raising the FSB isn't necessarily going to increase your temps, that's the vcore's job, but it *may*, don't hold me to that. Definitely set the HT lower, if it goes to high, just like any other setting, your computer won't boot properly, most likely won't POST. I find the HT one of my most easily forgotten settings to change, because I barely ever have to, and I only remember when my computer won't boot

If it's running at 59c stock, get a new cooler, like you said

I have a BE-2350 on an MSI K9N Plat. And it cannot go over 1050mhz HTT, the 570SLI chipset does not like really high FSBs.

And.. one question: HT multi one stop down is.... (normal value and new value?) and the same for RAM Speed (i have PC6400)
Normally for Phenom 95xx, 96xx and 97xx the HT link is 1800 mhz and 98xx is 2000mhz. Normal value of HT multi for 9500 is 9x which is multiplied by 200 (default reference clock or fsb) to obtain the real HT link speed. So for 9500 it is 9*200=1800mhz. For ur pc6400 800mhz RAM set it to pc5300 667mhz in the bios and raise reference clock. If u reach the max HT link or RAM speed (though good quality ram are ovrclockable to a good extent) then bring the necessary multi further one step down and continue.
Hope it helps.

MY bad. It varries. It however is always smarter to keep it around or under 1000. My opteron went to 1080 and thats all. Im an AMD Pro.

ok guys i got to it this morning and this is what i changed in my bios

FSB - 226
HT - X3
memory - 667

i'm clocked at 2.486 ghz and my processor is idleing around 40 degrees celcius right now on stock cooling. i have an arctic freezer 64 pro on the way so i should be able to push it further i hope. if i bump up my fsb to 228 i get a blue screen of death upon startup. also if my HT is set at X4 instead of X3 i can't get my FSB up past 216. now that my FSB won't go past 226 do i need to start cranking the voltages up a little? which ones? should i wait until my new heatsink gets here on wednesday before attempting that? i'm also confused on how to change memory timings.

i have a tool called OCCT, is it safe to use that tool or will my processor get to hot and fry itself?

sorry for all the questions, i'm just new to this and even though i've read up on overclocking i feel safer with the information you all provide. thanks for the help so far

Is your motherboard AM2+? AM2+ mobo support HT link upto 2.6 ghz but phenom9500 uses 1.8ghz. What CPU multi are u using? Could u post a bit more info?

i've 4200+ EE on 570SLi and i can up to 1333Mhz HT without any problem

Unfortunately, you're not gonna get the best results from an older Nforce chipset.

OC'ing phenoms is a fickle business. The multipliers are worked out from a complex formula that the Nforce 500 series doesnt really cater for. Also there is the point that you have no control over the speed of the L3 cache and mem controller on the chip. That will be another limiting factor.

The best pointers I could give would be turn down the Multi to about 8 and see if you can max out your Base frequency, adjusting your RAM speed if neccessary.

After you've found the max there, try and go for the best combination of base frequency and multiplier for your system. Higher base frequencies and lower multi's are better for maxing out Ram speed and HTT speed.

Voltage wise, no more than 1.45v on the vcore would be advisable for heat and lifespan, and adjust your RAM voltages accordingly.

I dont know about chipset voltages on 570 boards enough to really give you any hints, but if you can find out what the auto's are and then slightly raise them as you reach higher frequencies you'll find a touch more stability. The southbridge especially will get volt-hungry at higher speeds.

But, like I said, you really cant expect a Massive overclock if you pair a Phenom with a Nforce 500 chipset. Your best bets are the cheaper 790FX boards like the DFI M2RS, or a 780a nforce board like the Asus Crosshair II.
