Help with my OC and another quick question 245e

post #1 of 7
Thread Starter 
When I run everything on stock clocks,CPU-Z shows me:
HT link @ 2000mhz
NB @ 2000mhz

but I can never get these kinds of numbers when I overclock..
I know my motherboard supports it since I get these numbers on stock settings..

Here are my overclock settings for 3.5ghz
HT link @ 1000mhz
NB @ 1000mhz


HTT : 250
CPU Multiplier: 14x
HT Link: 800mhz
NB multi : 4x

Voltage:
CPU : stock 1.32v now @1.4v
DRAM: 2.2v
VCC SB: 1.36
HTT+1.2v : 1.26

RAM:
Memory Setting: DDR2 667 (778)
Memory Timings: 6-6-6-18-2T

If I set my NB link to equal 2000mhz (250*8), I can't even post boot.

Am I missing something here that I'm not understanding?

Another weird thing is when I'm overclock like my example... CPU-z freezes my PC 1 out of 3 times when it's loading "SPD"

What am I doing wrong?

Thanks

I am not to familiar with the AMD 245E. But what I have just seen is that it is 45 watt athlon processor. I don't think this chip sounds like it is meant to be a good overclocker. I could be wrong though.

Is your computer one of those all in one touch screen computers?

Also you should try starting with a lower overclock. Try like 3.2 GHZ first before 3.5.

Also isn't 2.2v for ram really high?

I just recently started overclocking. So I am really way more familiar with phenom II overclocking then athlons. I am sure someone who knows Athlons will tell you whats up.

I would try going for a higher voltage for your CPU 1.32v is ridiculously low for 3.5 GHZ. Try raising that and boost your HT and NB back too 2000MHZ.

You should really probably just go back to your default settings. Then slowly boost your speed. Don't just jump from 2.9 to 3.5 all at once. You need to go slowly probably .1 ghz at a time tops. And slowly adjust your settings trying to find stability. And there is no reason to ever drop your HT Link and NB down way below 2000 MHZ.

Oh and you said:

Memory Setting: DDR2 667 (778)

If your at 778 MHZ you need to lower your ram multiplier as well your ram is not rated for that speed.

Honestly it looks like your doing all kinds of things wrong. You are not taking the proper approach to overclocking from the looks of your settings. You must learn before you jump into overclocking.

No, this is the CPU that's in my specs on the bottom of my post.

Actually this 245e CPU is supposedly a pretty good overclocker as to what I have been reading. Easily reaches 3.5ghz and can get higher with good tweaks.


And 2.2v is actually the default voltage for my Patriot Viper Extreme

Hmm ok wait a sec.
I'm posting and stable at 3.5ghz with this voltage so are many people online.

My ram is DDR-2 800.. I have to lower it to 667 since I'm raising my HTT to 250
which with a CPU multiplier of 14 gives me 778! so I'm still within specs of my memory right? I'm not over my RAM speeds..
I don't have regular ram dividers in my BIOS.. it's a DFI MB and ram dividers are not in the bios now.. its all done with the HTT and cpu multi.
I referred myself to tutorials here and DDR2 Ram divider guide here : Link

Oh my mistakes. I should of read your cpu specs better. Yeah your ram should be fine if the default is 2.2v and 800 rated speed.

Hmm, well I guess if the only problem is you can't get your HT and NB stable at 2000 MHZ things are a bit more complicated. I would try backing off from 3.5 GHZ for now and try to see how high you can go while still having 2000 HT and 2000+ NB. Because at 3.5 GHZ for your cpu your NB should be 2500 MHZ and HT 2000 MHZ.

Once you encounter instability at 2000 MHZ for HT or NB you probably need to boost your cpu or NB voltage very slightly until it is stable. I don't think being 2000 MHZ for HT or NB would be the problem though since it already is that on stock. Which leads me to believe maybe your cpu is just not getting enough voltage.

But once again I don't know Athlons as well as Phenoms. So if what I am saying sounds wrong to you hopefully someone more knowledgeable will come help you out soon.

Thanks for your help

I went over to read the 245e overclock thread here
Here is what I did.. I raised the voltage to 1.4
Max cpu voltage is 1.55v.on these chips
I didn't change the CPU/NB voltage yet

you example says
Quote:
at 3.5 GHZ for your cpu your NB should be 2500 MHZ and HT 2000 MHZ.
Why would it be 2500 ?
At default clocks, 200x14.5 its 2000 NB and HT
