Problems Oc Phenom9850be

[beowulfhuntr]

Hi, with all of the other posts that are out there of everyone saying that they have their 9850's posting 3.0GHZ stable w/ benchmark runs i was kind of wondering why mine wont even load into windows vista past 2.8GHZ.

It's currently running at 32*C in windows as im typing this.

 

I have tried changing the FSB speed, CPU Multiplier to 15x, and even upping the voltage on the CPU.

It will let me see the CPU running at 3.0GHZ in bios, with temps not over 43*C even at 1.542Volts.

But It will get right where it's going to let me log in then just BSOD.

IRQL_NOT_LESS_OR_EQUAL and the CPU not being able to contact the second processor or something along the lines of that.

 

Do i need to upgrade to PC8500 in order for it to go any higher? Im currently running pc6400 Ballistix at 4-4-4-12-24 timings,a

MSI k9a2 platinum board, HD3870, and a zalman 9500A on the CPU(made sure thermal grease and everything are installed right).

 

Any and all help is appreciated as i am new to overclocking.

I've been having problems with my computer BSODing in the past too, except it has been ATIKMDAG.SYS errors.

So it might be the ram being bad or something... You guys tell me

 

but anyways heres an info screenshot off my overdrive stuff.

That IRQ error is usually due to a RAM instability Are those your rams rated timings? That chip, being the new revision without the TLB error, should do around 3ghz stable. It also may just be vista being picky...can you OC through vista using overdrive and then test for stability at those speeds, or will it lockup when those settings are applied from windows as well?

I believe most ppl who get higher overclocks with that cpu are running PC8500.

i believe they are, thats what the manufacturer tells me and what CPUZ tells me. The only thing is that the ram will not touch 2.2GHZ (what cpuz says) and is kind of iffy around 2.1, so i keep it at 2.0

and no when i try to up my voltage or my multiplier in AMDoverdrive while vista is running it will immediately freeze and reboot.

 

Have any suggestions on good pc8500 ram i can buy, i want at least 4gb cuz im running vista. I was looking at some gskill on newegg, 4gb of pc8500 for 144$ (2x2gb)

is what I've narrowed it down to..

I'm kind of iffy on the ballistix ram again just because the pc6400 has given me a lot of problems.

 

Any suggestions or comments on those three choices?

I would get the G.skill kit. It's a good kit and their chips are really dependable. Can't comment on OC potential.

There is no need to get PC8500! You just need to lower the divider on your mainboard!

What he said. You're about to throw money at an imaginary "problem."

[Guest ajmatson]

As king said you do not need to get faster speeds RAM. AMD chips are not as easy and as tolerant to overclocking like an Intel chip. You have to use your dividers and multipliers religiously. What is your HT multiplier set at? Have you dropped it down at all when you upped you CPU speed?

[ccokeman]

The latest AMD chips are not that great at overclocking. The socket 939 A64's did so quite nicely .
