Confused i am... AMD 4000+ question

[c0dec]

Hi,
Been trying to overclock my AMD 4000 to the 2.7 mark for the past hour and a half! I think ive tried everything but it just wont boot!! It sits at the XP loading screen but wont go any further. Ive managed to get my CPU at 2.7 within windows with Systool. Normally at this point i always thought it was a case of lack of voltage on something but ive tried upping all one click in turns with no luc

I was trying to my base my overclock on:

This guys hardware is very simular to my own apart from the CPU itself.

My 4000 has a Clawhammer core if this makes any difference.

Im half considering giving up and getting an Opty 170!!

Elp?

Regards
Dan

We need some settings. FSB, multi, HT multi, RAM setting including divider, t setting and timings, cpu vcore and any other things of interest to you and that you think might help us help you.

This is what im trying to boot with but its sitting on the XP loading screen:

FSB : 250
Multi : x11
HTT/LDT : x4
RAM Timings : 2-3-3-10 1T
Cpu vcore : 1.55v
Ram volts : 2.9v
Chipset volts : 1.73v

I have also tried the HTT/LDT at x3.

Everything else is in my sig.

Im abit confused with the 1:1 ratio settings and how to set them. Under my memory settings i set my memory to stick to 200mhz it still moves with my FSB. Although if i set it to 166mhz it will stay at that. Not that this should be a problem as my ram should be fine for anything up to 300mhz with the right voltage as far as i know.

Loosen your timings.

Try 2.5-4-4-10

Well... the Memory Mhz settings are divider settings. So your memory speed should scale when you change your HTT speed. I would recommend trying to change your CAS latency to 2.5 or maybe even 3 and see if you can push it further. I have trouble running 2 CAS latency on my setup. I usually can't go over maybe 2.0 Ghz with a CAS of 2. I usually run 2.5 for everyday use and 3 when I really want to see how hight the chip can go.

Ill try that shortly, cheers.

Also off topic but will an Opty 170 run on my motherboard? Its not shown as a working CPU on the DFI site but i assume it wasnt around when the board was made.

 

[c0dec]

Right, loosing the timings didnt work but i did in my second post type something wrong. Where i wrote "HTT/LDT : x4" the settings labed in my bios is infact called LDT/FSB Ratio which is currently set at x4. I dont know where to set the HTT or what else it would be called.

I am currently booted up at 2.7 but with a x12 multi with a 225 FSB. I would much rather have a lower multi with a higher FSB so push my ram alot further.

Sooo... what else can i try and where abouts would my HTT setting be? I have a popular older mobo, a DFI Lanparty NF3 Ultra-D which the latest bios version, someone must know where this setting is and also what i need to set it to to gain my extra FSB's!

Cheers again

You should be able to run a 170 with the newest BIOs. That is generally all that is required to run the newest chips. I bought this ASUS before Opterons came out and just had to update to the newest BIOs to get it to work, but who knows? DFI may be different.

If the system can run 225x12 try 245x11 and see if that'll go - virtually the same CPU clock but faster FSB. 250x11 may be over the limit for your CPU with that voltage.

The LDT is another name for the HT bus, different manufacturers different labels. 4x should be fine up to FSB 250 ...

 

[c0dec]

Tried 245x11 with no luck, it just sits on the XP booting screen. The things i tried to get it to boot where:

Loosen ram timings to 3.0-4-4-10 from 2.5-3-3-10
Change chipset voltage to 1.74v from 1.73v
Change core voltage to 1.56v from 1.55v
Change LDT to x3 from x4


What am i missing!?!

 

[Immortal_Hero]

Set a lower RAM divider and try it out. Like 133...

 

[Memphis69]

maybe your just at its limit... if you lowerd your HT from 5 to 4 and also 3 also try settin your ram at like 133 or maybe 166 see if that works and if you still can not get past that number sounds like your at its limit maybe mobo or cpu.. not sure, some cpu can clock like mad... and other are just " ok " idk tho im not expert

 

[c0dec]

Tried 133 with the same results

I always thought my motherboard was very good for clocking?! Maybe it is my CPU!? Its a 4000+ with a Clawhammer core.

Its wierd tho as i can get my CPU to 2.7 with a 12 multi but just not with the higher FSB and lower multi. Plus my PC boots up fine just will not go into XP.

 

[c0dec]

I have just been reading some old 4000+ reviews and the reviewers seem to have more luck getting the FSB higher on the San Diego rather than the Clawhammer that im running.

 

[Memphis69]

maybe your just at its limit from what i rember a high muilti is normaly easyer for the cpu to run.. but is not as " fast " so maybe thats it.. idk tho have you tryed to give it any extra juice?

 

[c0dec]

Yeah gave it 1.56v i was using 1.55v before.

I know this is a stupid question but in CPU-Z under my memory tab the FSBRAM is set to CPU/12. What sets this command? Im guessings its the HTT/LDT?

 

[Memphis69]

i think thats the devider that your ram is at...

 

[c0dec]

I think i may have found the problem found from google searching:

"Another thing to watch out for is if you are using sata drives that they are connected to 3&4 NOT 1&2. This is because when o’clocking channels 1&2 don’t like high HTT and will crap out over 240."

 

[c0dec]

OMG the above is correct, just unplugged my SATA drive and i can now magicly run 11 x 245 !!!!

Dont belive that
