Hi guys.

I have an X2 4400+, DFI Lanparty UT NF4 SLI-DR motherboard and 2gb Corsair XMS DDR500 and am in need of help to overclock this setup.

I have tried raising the FSB to 225mhz which gives me about 2.48ghz cpu speed but it will not go any higher, Am i really unlucky and it is one of the cores bumming out, It actually posts at much higher fsb but will not boot into windows and comes up with things like NTLDR is missing, I am assuming this is actually to do with the SATA bus so is there anyway of locking it?

Please help
 
You need to make sure the PCI-E frequency is locked at 100MHZ, this will stop you from overclocking the PCI bus and from getting your HD corrupted! Your RAM is rated to run at 2x 250MHz so that shouldn't be the problem, can you check if the timings are at their default 3-4-4-8? CPUZ will tell you, otherwise you can see what it says in the bios.

Make sure your htt multiplier isnt set to 5x as this would put the htt bus way over the 1000MHz most CPUs/boards can run at stable.....try lowering it to 4x.

If that doesnt work try upping the Vcore to between 1.5 and 1.55v but not 1.6 or over.

your getting confused,

pci-e @ 100-105
pci @ 33.33


op: drop your htt multi to 4x
set stock vcore and set correct cpu multi (11), push htt from 200 to 210, test with orthos for 1 hr, push up another 10 and test again for 1hr, keep doing this till you get errors, tell us where you get up too. :)
 
doesnt the pci bus run on a 1/3 divider from the pci-e bus? i.e. 33.3 x 3 = 100 ish ?

What cooling you got? With the same cpu and Lan Party ut ultra-d I can get 11x246= 2700Mhz @1.41V using a scythe ninja. My ram is the corsair 3200C2PT stuff on the 166 divider so it is running at 193Mhz 2-3-3-6 1T, you should be able to run yours 1:1 at 246 if you got decent cooling.
 
on my A8N i get 235mhz stable (2820mhz) with 4x HT and 1.45v cooled by modded thermaltake blue orb II, what cooling you using?
 
started to have a play with mine last night. easiest way is to drop the ram down on a large divider 1/2, lower the HTT to x3 and start clocking the cpu from there.

up 10mhz at a time, use super PI (32mb) test on both cores (not just one core) and keep increasing till Super PI fails and dsrop it 2/3 mhz till you find the maximum of your CPU. Becuase you ram is on a hugh divider you can rule out any ram issues at this stage.

The do the same with the ram, find the maximum. drop the multi on your cpu to x7 or x8 and start clocking the ram. Put it back to 1/1, need to read up on this more before starting but use the memcheck86 (should be an option in your bios on the DFI board) and run 10 passes of test 5 on memcheck and keep upping the speed by 10mhz each time. if it passes up again if not back off a little and test again.

This way you can find the maximum of your cpu and ram. Also increase the voltages a little if either fail. However be very careful with temps. I would say max 50 degrees on the cpu (personally).

I take no responsiliby for anything!!!

Will have some more testing tonight and over the weekend to find the max for my set up.

currently tested @ 220mhz and cleared, failed to get into windows on stock volts @ 230mhz on the cpu. (initially not looking like a good clocker! :( )
 
lol! cause im an idiot and it put the wrong processor in signiture, it has 12 multiplier so it'll be 4600+ right? :rolleyes:
 
im using an Arctic cooler 64 with a 120mm exhaust fan and a 120mm inlet fan, I have tried a few differant clocks and although the computer posts at high clocks the highest speec i got to with the processor was about 2.58ghz but the HTT was running at someting stupid like 600mhz, At the moment i have it running at 2486Mhz with a fsb of 226mhz and the HTT is showing as 1130Mhz

I just can help but thinking the only thing stopping me with higher clocks is the 2 Raptors in RAID 0 on SATA.

ill give it a few more goes.
 
the raptors should have nothing to do with your overclocks as far as i know.

Drop the htt to x 3 - this is probably causing you the instablility.

The HTT doesn't really make that much performance difference - keep it under 1000 so at present x 3 or x4 would be ideal.

anything over 1000 causes instabiulity issues

best advice really is to head over dfi street.com and they have a brilliant guide on ocing amd's with dfi mobo's :)
 
I think i might know the problem, My motherboard apparently has another 2 connectors, one next to the PCI-Express port and a floppy style on near that, These are used for stability but the problem is i have a modular power supply and silly me i can't find the cable that has the floppy connector on, i do have an old power supply though, Could i bodge a connector?
 
I made my own molex/floppy power cable from an old 250W psu I had kicking about, cut to the right length it is just the job. Just get a Y splitter and do some splicing.
 
with DFI boards you need to make sure all 4 power connections to the board are in place.

Testing last night and got cpu to pass 32Mb super pi on both cores @ 235Mhz. It needed 1.35v * 113% = 1.47v approx. Temps got a bit high 47 on cpu and 63 on PWMIC so need to get some more fans hooked up and keep going.

Only testing cpu max at the moment - ram is next and the put it all together.

Defo check out the dfi-street.com overclocking guide it's superb for DFI board owners.
 
O.k. i have just yanked my voltage up to 1.525 which is actually running at 1.48volts according to smartguardian, I ran Orthos which has just failed after 4 mins 20 seconds and the temps of the cpu were up to 63degrees and the PWMIC went up to 50 with the chipset only staying at abou 49 degrees.

The temps are pretty low when idling as the cpu is currently at 38 degrees, #i have a horrible feeling my cpu will not go over 2.6ghz esspecially not with much more voltage, Anyone got any more idea's?
 
I've no experience of the cooler you have but 63'C is crap tbh. It is not considered safe to go much above 50'C for amd processors afaik. You gonna have to get beef up your cooling options to get anything safe above stock it seems to me.
