Help with Overclock

[Xeon3D]

Hi.

I've got a DFI LanParty NFII Ultra Rev. B flashed with Evilous 4-29 Bios w/ 1-21 Romsip, a Barton 2500+ AQXEA [non mobile but unlocked week 31-03] (which I've read that is a good overclocker) and 2 Elixir DDR400 256 Mb DIMMS. The cpu is cooled by a TT Volcano 12.

 

I've got them running @ 11x180 @ 1.75v Vcore and the mems are 1:1 @ 2.8v.

 

I've tried (with 8rdavcore) to push it to 2.2Ghz 11x200 @ 1.85 and the system runs well for a few hours, computes 1M Super Pi, but then it reboots from nothing (not sure If I made my idea clear since English is not my first language).

 

I've seen reports from people with the same CPU's with astonishing OC reports (ok, they were watercooled), but why can't I even reach something like 2.3 Ghz with this?

 

Any help on this is appreciated, or if you have the same setup as I do please tell me your settings on the mem's, voltages and FSB.

 

Regards

:confused: Possible causes?

 

1. Too little memory voltage.

 

2. Too little cpu voltage.

 

3. Mis-set memory timings as in all left on auto or too tight

 

4. See above as the memory may be marginal.

 

5. Unfamiliar with that brand of memory and if you plan on getting any serious help in the early stages like this you need to list the memory spec's advised by the manufacturer and also the version of bios you are currently using.

 

Also if you have not made up a signature with an accurate detail of the pieces in your case>then you need to do so.

 

Sincerely, RGone...

I see you are running evilous's modded 4/29 bios, which I'm not too familiar with other than the trouble it caused in its stock incarnation with the 4 LEDS of death due to improper flashing procedures. Does your ram have heatspreaders on them? If not then please tell us what the actual chips have written on them and maybe we can help you more.

Elixir brand has it's own chips... I don't think they are relabled.

 

But I strongly recomned to check the mem timings as RGone said and check if you have CPC enabled. Try to disable it and if it's more stable then...

 

Also try to use either slots1+3 or 2+3 according to what you're using now. Don't play with mem settings like drv strength/slew rate if you did. It renders your system unstable most of the time.

 

Then try to use the 1-21 or 6-19 bioses. The 4-29 is not as stable, but perhaps... there was of course the possibility your hw loves it

All the settings that are memory related are default in the Bios, as I don't know what most of them mean. :confused:

I'm gonna try to up the mem's and cpu voltage and test 210x11

 

Probably I going to get a reboot

 

Update: Seems that it'll work @ 210x11 @1.9v Vcore and 2.9 Vdimm.

 

Gonna try and run Super PI and Prime (which I doubt it'll pass).

 

Super PI 1 Mb = 45 seg. (1 less than 11x200)

 

Prime Next

[Xeon3D]

Prime Didn't pass

 

And Meanwhile I've acquired a XP-M 2500+ (Thorton)

 

Can I please get reports from people with the same setup, and air cooling? (Mem timings, mem brand, fsb, vdimm, vcore, vchipset(?), etc...)

 

Thanks.

Elixir is notoriously bad memory with NF7 (cheap Nanya :mad: )

A thornton is a super locked Barton core. Mobiles are a totally different animal all together and are totally unlocked.

[thefortyfour]

my setup,

 

AMD Athlon T-Bred NIUHB 247*8 (1976Mhz)

VCore 1.6v

VDimm 2.8v

VDD Auto ( i don't know how high can i set it)

Temp idle 37 (CPU)

40 (System) ...i don't have fan on the SB hs

Temp load 43 (CPU)

46 (System)

 

i also use TT fan but only TT 11+ ( i know i will change it... )

 

p/s : elts_drac is right , thornton is a super locked barton core n

not a good overclocker

[thefortyfour]

and also...cpc off and timing is 2.5-3-3-11 with 1/21 bios.

my ram chipset is Hynix Bt-D43
