having trouble pushing x2 4400 to 2.4ghz

Jono8 · 23 May 2007 at 23:13

As the title says im having trouble pushing my x2 4400 past 2.3ghz.

As soo as i set the fsb past 210, it hangs on start up and i have to press delete at the start to reset.

Im fairly new to overclocking so i might be doing something wrong

My settings are as follows and my motherboard is a k8n-sli-pro

fsb:220
cpu multiplier:x11
vcore:1.400(althoughcpuzis showing 1.370. :confused:

)
ht multiplier x4 (so my ht link is 880)

I have set my ram speed down to 166mhz so that the fsb increase doesnt thwomp it over 200mhz.

Any ideas why it wont work?

If you where to set the cpu multiplier down to say 10x that would probably help...

When you say vcore? Is that the cpu voltage =|....i hope not!!!

wo sorry, yeh it is the cpu voltage, but i meant 1.400 and 1.370.lol sorry

Also what difference would bringing *** multiplier down do? Surely that would mean i would have to up the fsb to like 250 making more unstable no?

Delvis · 23 May 2007 at 23:29

It's hard to explain...bringing the cpu multi down to x10 makes the ht frequencey lower...which is good cause you need to keep that to 'around' 1000mhz...

Have you read the overclocking guide sticky on these forums?

They will help a lot more.

I had a gigabite board before that wouldn't go past 215 without lowering the HT to x2.
Try a lower divider on the ram to make sure.
You should also read the sticky on overclocking.

surely that would mean the ht spead would be like 500? isnt that too slow?

Katoom · 23 May 2007 at 23:44

I didn't notice much difference tbh, but it did then allow my opti 144 to go past 280.
Try to lower the HT to see if your chip will clock higher, you can then go back and fine tune to find your best settings.

Resolution: Dont overclock an X2.

I have one and I don't clock it. Isn't worth the extra heat to get another 200MHz.

but its only gone up about 2 degrees with a 100mhz clock. At the moment its 35 idle and 45 load. On top of that i plan to get sycthe cooler next week to cool it even more.

What motherboard and cooling have you got?

The overclocking sticky has everything you need to know.

ok here is an interesting one. In easytune(which i know is known as a pile of crap but still) it has overclocked it to 2.4ghz,no worries with cpu-z recognising all the right changes/speeds. Everytime i try and do it in the bios the system hangs on on posting. Any ideas?

Same thing on my gigabite board!

Really? Yeh beacuse when i try to go over 210fsb it simply doesnt boot. However using easytune and having it load last save at boot, it overclocks fine and doesnt hang. I mean i still need to fiddle around with voltages (some fails in orthus which i assume are vcore related) and temps e.t.c.(getting near 55-60 load so im thinking a good aftermarket cooler may be needed).

No problem 2.7ghz on mine, never goes above 50 degrees both cores at load. 245mhz CPU FSB, 11mhz CPU multi, +200mv vcore. 2.75v memory voltage. CAS 2, 1T command rate. Overvoltage for chipset (automatically increases it, guess must be intelligent setting)

980mhz HTT, 195mhz memory reported by CPU-Z. Probably 800mhz HTT and 186mhz bios settings

Jono8 · 24 May 2007 at 01:28

I just simply don't know why the bios won't let me go over 210? ive tried raisng the voltage, changing the multipliers and fsb combinations. ive put my ddr400 ram down to 166mhz because i don't want to bring my memory into this. One thing i wanted to know is what is a ram divider?

The Halk · 24 May 2007 at 01:51

Ram divider is, for example, where you run your FSB at 200, and your memory at 166. Your motherboard will implement a divider.

Where a processor has a locked multiplier, a divider is the way to get a higher CPU speed without a higher memory speed.

From what you've said though, you are already running a divider.

Ok sweet. Thanks for all your help guys but i think i have it sorted.

I updated to the latest bios (f9) and it seems gigabyte have added some options and fixed whatever the problem was. Running at 2.4ghz from the bios now with a 250fsb x 9.5 at a vcore of 1.420. memory was at 166 but back to 200mhz due to the fsb. One last bit of advice:my ht link is 750mhz, does it need to be bigger?

Just going to do some stability tests tomorrow and then get a top of the line cpu cooler and try and push it to 2.6ghz.

I have to say i'm getting into this overclocking lark!

Thanks again
